Description

Technical Field

[0001] The present invention relates to the technical field of gate slot construction of arc gates, in particular to a gate slot construction device and a construction method for arc gates. Background Technique

[0002] With the development of the water conservancy and hydropower industry, in gate slot construction, straight gate slots or inclined gate slots mostly adopt one-stage direct embedding construction, which greatly advances the installation period of the straight (inclined) gate slots. However, the installation of the gate slot track (arc gate track) of the arc gate often consumes a large amount of time in the whole gate slot installation. Therefore, the one-stage installation of the gate slot of the arc gate can advance the progress of the whole gate slot installation project and improve the installation quality of the gate slot. The arc-shaped working gate realizes water sealing by relying on the seal between the arc-shaped gate and the track, and has higher requirements for the manufacturing, installation accuracy and quality of the arc-shaped gate and the track. The gate slot track of the arc gate is arc-shaped in the upstream and downstream directions, while the tracks of the straight gate slot or the inclined gate slot are all straight surfaces. At present, the existing gate slot construction devices can only be used for the straight-surface gate slot tracks. For the arc gate track, the projected length of its upstream and downstream directions on the horizontal plane is mostly more than 6m. The existing gate slot construction devices cannot play a complete supporting and adjusting role for the arc gate track and cannot construct the arc gate track. At present, the construction of the gate slot of the existing arc gate still adopts the traditional two-stage installation, which has a greater impact on the whole construction period, safety and quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a gate slot construction device and a construction method for arc gates in view of the problem that the existing gate slot construction devices cannot be used for the construction of arc gate tracks.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A gate slot construction device for arc gates includes a support adjustment system and a mobile platform. The support adjustment system includes three situations.

[0006] Situation a: The support adjustment system includes columns on both sides in the X direction. The X direction is the width direction of the arc gate. The columns are arranged vertically. The two columns on both sides are connected by a cross beam. The cross beam can ensure that the distance between the two columns remains unchanged. The columns are arranged in the corresponding gate slot to be constructed.

[0007] Situation b: The support adjustment system includes columns on both sides in the X direction. The X direction is the width direction of the arc gate. The columns are arranged vertically. The tops of the two columns on both sides are connected by a cross beam. The cross beam can ensure that the distance between the tops of the two columns remains unchanged. There is a pouring space for the pier in the middle in the X direction between the two columns on both sides and below the cross beam. The two columns on both sides are respectively arranged in the gate slots to be constructed of the arc gates on both sides of the same pier.

[0008] Case c: The support adjustment system includes a column in the X direction, the X direction is the width direction of the arc door, the column is arranged in the vertical direction, and the column corresponds to the door slot to be constructed on the side pier;

[0009] The support adjustment system also includes a plurality of support positioning mechanisms for supporting the arc door track along the X direction, wherein the support positioning mechanisms are arranged corresponding to the upright posts, and the support positioning mechanisms can adjust their support lengths in the X direction;

[0010] The mobile platform is arranged on the support adjustment system, and the mobile platform is arranged along the Y direction, which is the upstream and downstream direction of the arc gate. The mobile platform and the support adjustment system restrict each other in the vertical direction. The support adjustment system can move in the Y direction along the mobile platform. The distance that the support adjustment system can move in the Y direction is adapted to the length of the arc gate track in the Y direction. The support adjustment system can be fixed to the mobile platform in the Y direction.

[0011] In this scheme, when the support adjustment system is in case a, the two columns correspond to the gate slots on both sides of the arc gate, and the columns on both sides are arranged vertically, connected by the middle crossbeam to form a support, so as to ensure that the spacing between the columns on both sides remains unchanged, thereby ensuring the verticality of the columns. The arc gate track is located on the outer side of the column in the X direction and on the opposite side of the columns on both sides. The arc gate track is supported and positioned along the X direction by the support positioning mechanism, so that when pouring concrete, the arc gate track will not tilt under the lateral stress in the X direction, thereby ensuring the pouring quality of the arc gate track. The support positioning mechanism can adjust its support length in the X direction, firstly, it can facilitate the positioning of the arc gate track, and secondly, when the column needs to be lifted, the support length of the support positioning mechanism needs to be shortened to avoid damage to the arc gate track that has been poured with concrete when the column needs to be lifted. When the support adjustment system is in case b, it can be used to cast gate piers; when the support adjustment system is in case c, it can be used to cast side piers. In cases a, b and c, the functions of the columns and the support positioning mechanism are the same.

[0012] The mobile platform is arranged along the upstream and downstream directions of the radial gate. The mobile platform and the support adjustment system are mutually restricted vertically, that is, the mobile platform and the support adjustment system need to be raised together vertically to avoid affecting their vertical position relationship after elevation, thereby ensuring their position accuracy and reducing the impact on the gate slot construction of the elevated radial gate. The support adjustment system can move in the Y direction along the mobile platform, that is, move along the upstream and downstream directions, so that the support adjustment system can support different upstream and downstream positions at different heights. Moreover, the distance that the support adjustment system can move in the Y direction is adapted to the length of the radial gate track in the Y direction, so that it can support different heights and different upstream and downstream position parts of the radial gate track. Before support, the support adjustment system can be fixed to the mobile platform to ensure the stability of the support, so as to ensure the accuracy of the radial gate track during the concrete pouring process.

[0013] The gate slot construction device of the radial gate adopting this solution can support and position different heights and different upstream and downstream position parts of the radial gate track, so that the gate slot installation of the radial gate and the corresponding concrete pouring can be directly completed in the first stage. Compared with the second-stage construction, its construction period is shorter, the construction quality is better, and the safety is higher.

[0014] Preferably, a corresponding mobile platform is provided on each column. The mobile platform and the corresponding column are mutually restricted vertically. All the columns can synchronously move in the Y direction along the corresponding mobile platform, and the column can be fixed to the corresponding mobile platform in the Y direction.

[0015] The support positioning mechanism is arranged on the column. The column is the main force-bearing support part. By respectively arranging mobile platforms on the two side columns, the column moves along its respective mobile platform, and the columns move synchronously when moving on the corresponding mobile platform, making the movement of the entire support adjustment system in the upstream and downstream directions more stable.

[0016] Preferably, the mobile platform includes a frame, a slide rail, a moving device and a rolling frame. The slide rail is fixed to the frame in the Y direction. The rolling frame is arranged on the slide rail. The column is fixedly arranged with the rolling frame. The moving device is used to control the rolling frame to drive the column to move in the Y direction along the slide rail.

[0017] Adopting the above mobile platform makes the movement of the column in the upstream and downstream directions on the mobile platform more stable, more accurate and safer.

[0018] Preferably, it further includes a lifting system, and the lifting system is used to raise the support adjustment system and the mobile platform as a whole.

[0019] Preferably, the lifting system includes a lifting track and a hydraulic cylinder. The lifting track is vertically arranged and is disposed between the column and the cast-in-place concrete on the corresponding side of the arc gate. The lifting track can be fixed to the cast-in-place concrete. The hydraulic cylinder is vertically arranged on the lifting track, and the hydraulic cylinder can jack up the support adjustment system and the mobile platform integrally along the lifting track.

[0020] With the above-mentioned lifting system, the lifting track is disposed between the column and the cast-in-place concrete on the corresponding side of the arc gate, which can avoid interfering with the support adjustment system and enable the lifting track to be fixed to the cast-in-place concrete, ensuring the stability after the vertical arrangement of the lifting track. Moreover, the hydraulic cylinder is vertically arranged on the lifting track, that is, it can ensure the installation accuracy of the lifting track based on the cast-in-place concrete, ensure the installation accuracy of the hydraulic cylinder based on the installation accuracy of the lifting track, and with the lifting track as the guide, the hydraulic cylinder can vertically jack up the support adjustment system and the mobile platform integrally, ensuring the position accuracy of the support adjustment system and the mobile platform integrally after rising, and further avoiding affecting the construction of the subsequent gate slot. With the above-mentioned lifting system, the jacking accuracy is higher, which can further reduce the influence on the construction accuracy of the subsequent gate slot, and it is convenient to install and safe to use.

[0021] Preferably, the lifting system further includes a base, a lifting seat and a connecting seat. The base is disposed on the side of the lifting track close to the corresponding cast-in-place concrete, and the base is connected to the side surface of the corresponding cast-in-place concrete. The lifting seat, the hydraulic cylinder and the connecting seat are all disposed on the side of the lifting track close to the column. The upper end of the hydraulic cylinder is connected to the connecting seat and the lower end is connected to the lifting seat. The base, the lifting seat and the connecting seat can all slide along the lifting track, and the base, the lifting seat and the connecting seat can all be fixed to the lifting track. The connecting seat is detachably connected to the corresponding base, and the connecting seat is used to connect the frame.

[0022] Before the hydraulic cylinder jacks up, both the lifting seat and the base are fixed to the lifting track, the connecting seat can slide upward along the lifting track, the hydraulic cylinder jacks up the connecting seat, the connecting seat slides upward along the lifting track, drives the frame to move upward, and the frame drives the column to move upward, so that the support adjustment system and the moving platform as a whole rise by one stroke; fix the connecting seat to the lifting track or the base, release the fixation of the lifting seat to the lifting track so that the lifting seat can slide along the lifting track, and then it is possible to take the connecting seat as a fixed point and lift the lifting seat upward by one stroke through the retraction of the hydraulic cylinder; then fix the lifting seat to the lifting track and make the connecting seat able to slide upward along the lifting track, and then the subsequent jacking can be continued. By adopting this cyclic method, the support adjustment system and the moving platform as a whole can be continuously lifted, and it is not restricted by the jacking stroke of the hydraulic cylinder. The jacking height is the height of the lifting track, and the connecting seat cannot exceed the top of the lifting track.

[0023] When the lifting seat is at the top of the lifting track, the moving platform cannot be jacked up continuously. Therefore, the lifting track can be lifted. Before lifting the lifting track, fix the lifting seat to the lifting track and fix the connecting seat to the corresponding base. The lifting track can slide upward, and the lifting track is lifted upward by one stroke through the retraction of the hydraulic cylinder; then fix the lifting track to the base or the connecting seat, release the fixation of the lifting seat to the lifting track, and jack up the lifting seat through the hydraulic cylinder to move it downward by one stroke along the lifting track; then fix the lifting seat to the lifting track again and release the fixation of the lifting track to the base or the connecting seat, and the lifting track can be lifted by one stroke again. By adopting this cyclic method, the lifting track can be continuously lifted, and this lifting method is not restricted by the jacking stroke of the hydraulic cylinder. The lifting height is the height of the lifting track.

[0024] By adopting the above cyclic jacking and lifting methods, the lifting of the support adjustment system and the moving platform as a whole can be unrestricted by the jacking stroke of the hydraulic cylinder and the length of the lifting track, with higher applicability, convenient operation and safe use.

[0025] Preferably, the lifting systems are respectively arranged at both ends of the moving platform in the Y direction. The frame is of a rectangular structure. Through grooves are respectively arranged at two corners of the side of the frame adjacent to the cast-in-place concrete. The through grooves open towards the cast-in-place concrete, and the lifting track passes through the through grooves.

[0026] Setting the lifting systems in the through grooves at the corners at both ends of the moving platform in the Y direction can make the lifting process more stable and safe, and will not affect the upstream and downstream movement of the support adjustment system on the moving platform. And the through grooves can guide the upward movement of the lifting track.

[0027] Preferably, it further includes a gate slot formwork, which is arranged between the column and the corresponding radial gate track. The gate slot formwork is provided with through holes in the X direction, and the support and positioning mechanism passes through the through holes to support the corresponding radial gate track.

[0028] The gate slot formwork is the side formwork on the side of the gate chamber of the radial gate. It is arranged between the column and the corresponding radial gate track to support the concrete pouring on both sides in the upstream and downstream directions of the radial gate track. The support and positioning mechanism passes through the through holes on the gate slot formwork to support the corresponding radial gate track, enabling the support and positioning mechanism on the support adjustment system to support and position the radial gate track to resist the lateral stress of the concrete pouring at the radial gate track and ensure the accuracy of the radial gate track after concrete pouring. Moreover, the gate slot formwork can adopt a whole plate and be lifted as a whole, without the need for continuous disassembly and reassembly like the assembled formwork. It avoids a large amount of assembly of the formwork at or around the radial gate track and greatly improves the construction efficiency.

[0029] Preferably, a plurality of rows of the through holes are vertically distributed on the gate slot formwork, and the trend of all the rows of the through holes is adapted to the radian of the radial gate track;

[0030] and / or,

[0031] A plurality of adjusting rods are arranged on the side of the gate slot formwork close to the column. The adjusting rods are inclined. One end of the adjusting rod is connected to the moving platform, and the other end is fixed to the gate slot formwork. The adjusting rod can adjust its support length;

[0032] and / or,

[0033] A plurality of tie bars are arranged on the side of the gate slot formwork close to the radial gate track. The tie bars are misaligned with the radial gate track. One end of the tie bar is connected to the gate slot formwork, and the other end is connected to the top surface of the poured concrete or the bottom sill.

[0034] When a plurality of rows of the through holes are vertically distributed on the gate slot formwork, the trend of all the rows of the through holes is adapted to the radian of the radial gate track. In this way, without raising the gate slot formwork, it can adapt to the concrete pouring of a higher radial gate track, or the construction of the radial gate track can be carried out in multiple times vertically.

[0035] Before pouring concrete, the gate slot formwork is supported on the moving platform through the adjusting rods, which can ensure the verticality of the gate slot formwork. After the poured concrete is formed, by shortening the support length of the adjusting rods, the gate slot formwork can be separated from the concrete.

[0036] The tie bars on the side of the gate slot formwork close to the radial gate track connect the gate slot formwork to the top surface of the poured concrete or the bottom sill, which can offset the lateral stress on the gate slot formwork during concrete pouring.

[0037] Preferably, part of the support and positioning mechanism is adapted to be arranged according to the curve trend of the corresponding radial gate track, so as to better support and position the radial gate track.

[0038] A method for constructing the gate slot of a radial gate, which uses the above-mentioned gate slot construction device for the radial gate to construct the gate slot of the radial gate, including the construction of the gate slot of the radial gate before the support adjustment system of the gate slot construction device for the radial gate is raised and the construction of the gate slot of the radial gate when the support adjustment system needs to be raised;

[0039] The construction of the gate slot of the radial gate before the support adjustment system is raised includes steps S01 - S07:

[0040] S01. Install the bottom sill of the gate slot of the radial gate and pour the concrete of the gate slot to the elevation of the bottom sill;

[0041] S02. Measure and set out the installation positions of the radial gate track, the support adjustment system and the gate slot formwork. According to the measurement and setting out, install the support adjustment system, the gate slot formwork and the first layer of the radial gate track to be constructed, so that the gate slot formwork is located between the columns of the support adjustment system and the corresponding radial gate track to be constructed, and then support and position the radial gate track through the struts of the support and positioning mechanism;

[0042] S03. Connect formworks on the basis of the gate slot formwork to form the pouring space of the first layer of pier or side pier, and then pour the first layer of concrete;

[0043] S04. After the concrete of the upper layer reaches the design strength, if the height of the poured concrete is less than H (H is the maximum height after the lifting system and the mobile platform are installed), retract the struts of the support and positioning mechanism, release the fixation of the support adjustment system, move the support adjustment system along the Y direction to the predetermined position adapted to the radial gate track of the next layer to be constructed and fix it, and then enter step S05; if the height of the poured concrete is greater than or equal to H, enter the construction stage of the gate slot of the radial gate when the support adjustment system needs to be raised;

[0044] S05. Install the gate slot formwork and the radial gate track to be constructed in the current layer, so that the gate slot formwork is located between the columns of the support adjustment system and the corresponding radial gate track to be constructed, and then support and position the radial gate track through the struts of the support and positioning mechanism;

[0045] S06. Connect formworks on the basis of the gate slot formwork to form the pouring space of the pier or side pier in the current layer, and then pour the concrete in the current layer;

[0046] S07. Repeat step S04;

[0047] The construction steps of the gate slot of the radial gate when the support adjustment system needs to be raised include S1 - S6:

[0048] S1. Release the fixed support of the support adjustment system for the upper-layer already constructed radial gate track;

[0049] S2. Install the mobile platform and the lifting system so that, under the condition that the fixed support of the support adjustment system is released, the support adjustment system can move upstream along the mobile platform, and the lifting system can lift the mobile platform and the support adjustment system as a whole;

[0050] S3. Release the fixation of the support adjustment system so that there is no interference during the upward movement of the support adjustment system, and then use the lifting system to lift the support adjustment system and the mobile platform as a whole to the corresponding support height of the lower-layer unconstructed radial gate track; and release the fixation of the support adjustment system so that there is no interference during the Y-direction movement of the support adjustment system, and move the support adjustment system along the Y-direction to the corresponding support Y-direction position of the lower-layer unconstructed radial gate track through the mobile platform;

[0051] S4. Fix the support adjustment system and the mobile platform, install the gate slot formwork and the radial gate track to be constructed in the current layer, so that the gate slot formwork is located between the columns of the support adjustment system and the corresponding radial gate track to be constructed, and then support and position the radial gate track through the struts of the support positioning mechanism;

[0052] S5. Connect formworks on the basis of the gate slot formwork to form the pouring space for the pier or side pier in the current layer, and then pour the concrete in the current layer;

[0053] S6. After the concrete in the upper layer reaches the design strength, repeat steps S3 - S5 until the construction of the gate slot of the radial gate is completed.

[0054] Adopting the above construction method for the gate slot of the radial gate can directly construct the gate slot of the radial gate and the corresponding concrete in the first stage, with a shorter construction period, better construction quality, and higher safety.

[0055] Preferably, step S6 is replaced with S6': After the concrete in the upper layer reaches the design strength,

[0056] If the support height of the to-be-constructed radial gate track in the next layer is still within the height range of the support adjustment system: Release the fixation of the support adjustment system to make the Y-direction movement of the support adjustment system unobstructed; then move the support adjustment system along the Y-direction to the corresponding support Y-direction position of the to-be-constructed radial gate track in the next layer through the mobile platform; then fix the support adjustment system; then install the gate slot formwork and the to-be-constructed radial gate track in the current layer, so that the gate slot formwork is located between the columns of the support adjustment system and the corresponding to-be-constructed radial gate track; then support and position the radial gate track through the struts of the support positioning mechanism; then connect formworks on the basis of the gate slot formwork to form the pouring space of the pier or side pier in the current layer, and then pour the concrete in the current layer; then repeat step S6', until the construction of the gate slot of the radial gate is completed;

[0057] If the support height of the to-be-constructed radial gate track in the next layer is above the height range of the support adjustment system: Repeat steps S3 - S6' until the construction of the gate slot of the radial gate is completed.

[0058] In the above solution, the single-time elevation of the support adjustment system can adapt to the construction of the to-be-constructed radial gate tracks of multiple layers.

[0059] Preferably, the gate slot formwork is a whole plate, the gate slot formwork is arranged between the columns and the corresponding radial gate track, the gate slot formwork is provided with through holes in the X-direction, and the struts of the support positioning mechanism need to pass through the through holes on the gate slot formwork to support and position the corresponding radial gate track. In this way, the use of assembled formworks is avoided, and the gate slot formwork can be lifted as a whole, which avoids a large number of assemblies of formworks at or around the radial gate track, and greatly improves the construction efficiency.

[0060] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0061] 1. The gate slot construction device of the radial gate described in the present invention includes a support adjustment system and a mobile platform. Under the action of a lifting device, the mobile platform and the support adjustment system can be lifted together vertically, and the support adjustment system can move in the upstream and downstream directions along the mobile platform, so that the support adjustment system can support different upstream and downstream positions at different heights, and the distance that the support adjustment system can move in the Y-direction is adapted to the length of the radial gate track in the Y-direction, so that it can support and position different height and different upstream and downstream position parts of the radial gate track, and the support adjustment system and the mobile platform can be fixed before support to ensure the stability of the support, so as to ensure the accuracy of the radial gate track during the concrete pouring process. It can directly complete the installation of the gate slot of the radial gate and the pouring of the corresponding concrete in one stage. Compared with the two-stage construction, its construction period is shorter, the construction quality is better, and the safety is higher.

[0062] 2. The door slot construction device of the arc door described in the present invention also includes a lifting system, which can ensure the installation accuracy of the lifting track based on the poured concrete, and the installation accuracy of the hydraulic cylinder based on the installation accuracy of the lifting track. Guided by the lifting track, the hydraulic cylinder can vertically lift the support adjustment system and the mobile platform as a whole, ensuring the position accuracy of the support adjustment system and the mobile platform as a whole after lifting, thereby avoiding affecting the subsequent door slot construction. The lifting system can also adopt a cyclic lifting and lifting method, so that the lifting of the support adjustment system and the mobile platform as a whole can be free from the limitation of the lifting stroke of the hydraulic cylinder and the length of the lifting track, which has higher applicability, is easy to operate, and is safe to use.

[0063] 3. The door slot construction device of the arc door of the present invention also includes a door slot template, which can cover the entire arc door track to realize the pouring support of concrete on both sides of the arc door track in the upstream and downstream directions; and the door slot template is provided with a through hole, and the support positioning mechanism passes through the through hole on the door slot template to support the corresponding arc door track, so that the arc door track can be supported and positioned by the support positioning mechanism on the support adjustment system to resist the lateral stress of the pouring of concrete at the arc door track, and ensure the accuracy of the arc door track after the concrete is poured. Before pouring concrete, the door slot template is supported on the mobile platform by the adjusting rod to ensure the verticality of the door slot template. After the poured concrete is formed, the door slot template can be separated from the concrete by shortening the support length of the adjusting rod. The tension bar on the side of the door slot template close to the arc door track connects the door slot template to the top surface or bottom sill of the poured concrete, which can offset the lateral stress on the door slot template when pouring concrete. The adjusting rod and the tension bar have different functions and do not interfere with each other, so as to avoid the influence of the lateral stress of the concrete on the mobile platform and the support adjustment system.

[0064] 4. The door slot construction method of the arc door described in the present invention can directly construct the door slot of the arc door and the corresponding concrete in the first phase, which shortens the construction period, improves the construction quality, and increases safety.

[0102] This embodiment provides a gate slot construction device for an arch gate. Refer to Figures 1 - 5 , which includes a support adjustment system 1 and a mobile platform 2. The support adjustment system 1 includes columns 11 on both sides in the X direction. The X direction is the width direction of the arch gate. The columns 11 are arranged vertically. The two columns 11 on both sides are connected by a cross beam 12. The cross beam 12 can ensure that the distance between the two columns 11 remains unchanged. The support adjustment system 1 further includes a plurality of support positioning mechanisms 14 for supporting the arch gate track 5 in the X direction. The support positioning mechanisms 14 are arranged corresponding to the columns 11, and the support positioning mechanisms 14 can adjust their support length in the X direction;

[0103] The mobile platform 2 is arranged on the support adjustment system 1. The mobile platform 2 is arranged in the Y direction. The Y direction is the upstream and downstream direction of the arch gate. The mobile platform 2 and the support adjustment system 1 are mutually restricted in the vertical direction. The support adjustment system 1 can move in the Y direction along the mobile platform 2. The distance that the support adjustment system 1 can move in the Y direction is adapted to the length of the arch gate track 5 in the Y direction. The support adjustment system 1 can be fixed with the mobile platform 2 in the Y direction.

[0104] In this solution, the arch gate track refers to the gate slot track of the arch gate, and the gate slot refers to structural members including the bottom sill, arch gate track, etc. The two columns 11 correspond to the gate slots on both sides of the arch gate, such as Figure 20As shown, the vertical columns 11 on both sides are vertically arranged and connected by the middle cross beam 12 to form a support, ensuring that the distance between the two vertical columns 11 remains unchanged, and further ensuring the perpendicularity of the vertical columns 11. Moreover, the arc gate track 5 of the arc gate is located outside the vertical columns 11 in the X direction, that is, on the side where the two vertical columns 11 face away from each other. The arc gate track 5 is supported and positioned along the X direction by the support positioning mechanism 14, which can ensure that the arc gate track 5 will not tilt under the lateral stress in the X direction during concrete pouring, thereby ensuring the pouring quality of the arc gate track 5. The support positioning mechanism 14 can adjust its support length in the X direction. Firstly, it can facilitate the positioning and support of the arc gate track 5, adjust the size and accuracy of the arc gate track 5, and at the same time form a support for the arc gate track 5. Secondly, when the vertical column 11 needs to be lifted, the support length of the support positioning mechanism 14 needs to be shortened to avoid damaging the arc gate track 5 where the concrete has been poured during the lifting of the vertical column 11.

[0105] As Figures 6 - 7 shown, a connecting platform 13 is also connected between the two vertical columns 11. The connecting platform 13 is used for the connection between the left and right vertical columns 11. Construction workers can reach the right vertical column 11 from the left vertical column 11 through the connecting platform 13 to form a working platform. The upper and lower cross beams 12 also have railings, and the lower cross beam 12 also has a ladder. The ladder is connected to the upper connecting platform 13 to form a safety passage for all platforms. And the support positioning mechanism 14 is arranged on the side of the vertical column 11 facing away. Specifically, as Figure 8 shown, the vertical column 11 is a rectangular frame structure, which includes several cross bars 112 and four vertical bars 111. The several cross bars 112 connect the four vertical bars 111 together to form a rectangular frame structure. Among them, the support positioning mechanism 14 can be arranged on the cross bar 112 or the vertical bar 111. In this embodiment, the support positioning mechanism 14 can be arranged on the cross bar 112 and can slide in the upstream and downstream directions along the cross bar 112. However, the support positioning mechanism 14 can also be fixedly arranged on the cross bar 112, but part of the support positioning mechanism 14 needs to be adapted to the curve trend of the corresponding arc gate track 5, as Figure 8 shown, at the upper part of the vertical column 11, the support positioning mechanism 14 is adapted to the curve trend of the corresponding arc gate track 5, which can better support and position the arc gate track 5.

[0106] As Figure 2 and Figure 5As shown, the mobile platform 2 is arranged along the upstream and downstream directions of the radial gate. The mobile platform 2 and the support adjustment system 1 are vertically restricted from each other, that is, the mobile platform 2 and the support adjustment system 1 need to be raised together vertically to avoid affecting their positional relationship after vertical elevation, thereby ensuring their positional accuracy and reducing the impact on the gate slot construction of the elevated radial gate. The support adjustment system 1 can move in the Y direction along the mobile platform 2, that is, move along the upstream and downstream directions, so that the support adjustment system 1 can support different upstream and downstream positions at different heights. Moreover, the distance that the support adjustment system 1 can move in the Y direction is adapted to the length of the radial gate track 5 in the Y direction, so that it can support different height and different upstream and downstream position parts of the radial gate track 5. Before support, the support adjustment system 1 can be fixed to the mobile platform 2 to ensure the stability of the support, so as to ensure the accuracy of the radial gate track 5 during the concrete pouring process.

[0107] In this solution, it is only necessary for the support adjustment system 1 to be able to move in the upstream and downstream directions along the mobile platform 2. However, the support positioning mechanism 14 is arranged on the column 11, and the column 11 is the main force-bearing support part. By arranging the mobile platforms 2 on both sides of the column 11 respectively, the column 11 moves along its respective mobile platform 2, and the column 11 moves synchronously corresponding to the mobile platform 2, making the movement of the entire support adjustment system 1 in the upstream and downstream directions more stable. Specifically, as Figure 3 shown, each column 11 is provided with a corresponding mobile platform 2. The mobile platform 2 and the corresponding column 11 are vertically restricted from each other. The two columns 11 can synchronously move in the Y direction along the corresponding mobile platform 2, and the column 11 can be fixed to the corresponding mobile platform 2 in the Y direction. In this embodiment, the mobile platform 2 is also a rectangular frame structure. It adopts the method of partially embedding the middle part of the column 11 to share the space with the middle part of the column 11, and at the same time, it is convenient for the formation of vertical restrictions between the members to ensure that the support adjustment system 1 and the mobile platform 2 are integrated vertically; of course, the restrictions between the support adjustment system 1 and the mobile platform 2 can be separated by disassembly. The part of the mobile platform 2 that is not embedded in the column 11 is located outside the opposite sides of the two columns 11, which is convenient for connecting with the lifting equipment or the lifting system 3, avoiding the direct vertical restriction of the lifting equipment or the lifting system 3 on the column 11, and thus avoiding affecting the function of the support adjustment system 1 moving on the mobile platform 2.

[0108] In this embodiment, as Figures 9 - 12As shown in the figure, the mobile platform 2 includes a frame 21, a slide rail 22, a mobile device 23, and a rolling frame 24. The slide rail 22 is fixed to the frame 21 along the Y direction. The rolling frame 24 is arranged on the slide rail 22. The column 11 is fixedly arranged with the rolling frame 24. The mobile device 23 is used to control the rolling frame 24 to drive the column 11 to move along the slide rail 22 in the Y direction, and the mobile device 23 can provide power. The frame 21 is the support core of the entire mobile platform 2 and is used to bear the weight of the entire support adjustment system 1. With the above mobile platform 2, the column 11 has high moving stability, higher precision, and greater safety in the upstream and downstream directions of the mobile platform 2. In this embodiment, an operation platform 25 can also be arranged on the top of the frame 21 for convenient construction. And the operation platform 25 is arranged on the top of one side of the mobile platform 2 in the middle of the X direction close to the support adjustment system 1, which is convenient for installation, maintenance, and safety protection. The frame 21, the slide rail 22, the mobile device 23, and the rolling frame 24 are arranged on the other side of the mobile platform 2 to avoid mutual interference. As Figure 3 shown, the operation platform 25 and the connection platform 13 are set at the same height to facilitate the connection of the operation platforms 25 on both sides.

[0109] In this solution, the overall lifting of the support adjustment system 1 and the mobile platform 2 can adopt a lifting system 3, and the lifting system 3 can adopt existing lifting equipment, etc. The lifting system 3 can be installed on the cast-in-place concrete 7 in the gate slot orifice of the arc gate to lift the entire support adjustment system 1 and the mobile platform 2 of the arc gate upward.

[0110] As a preferred implementation manner, as Figure 13As shown, the lifting system 3 includes a lifting rail 33 and a hydraulic cylinder 35. The lifting rail 33 is vertically arranged. The lifting rail 33 is arranged between the poured concrete 7 on the corresponding side of the column 11 and the arc gate. The lifting rail 33 can be fixed to the poured concrete 7. The hydraulic cylinder 35 is vertically arranged on the lifting rail 33. The hydraulic cylinder 35 can lift the support adjustment system 1 and the mobile platform 2 as a whole upward along the lifting rail 33. By adopting the above-mentioned lifting system 3, the lifting track 33 is arranged between the cast concrete 7 on the corresponding side of the column 11 and the arc door, which can avoid interference with the support adjustment system 1, and enable the lifting track 33 to be fixed to the cast concrete 7, ensuring the stability of the lifting track 33 after the vertical setting, and the hydraulic cylinder 35 is vertically arranged on the lifting track 33, that is, the installation accuracy of the lifting track 33 can be guaranteed based on the cast concrete 7, and the installation accuracy of the hydraulic cylinder 35 can be guaranteed by the installation accuracy of the lifting track 33. Guided by the lifting track 33, the hydraulic cylinder 35 can vertically lift the support adjustment system 1 and the mobile platform 2 as a whole, ensuring the position accuracy of the support adjustment system 1 and the mobile platform 2 as a whole after lifting, thereby avoiding affecting the subsequent construction of the door slot. By adopting the above-mentioned lifting system 3, the lifting accuracy is higher, which can further reduce the impact on the accuracy of the subsequent construction of the door slot, and it is easy to install and safe to use.

[0111] Furthermore, due to the limitation of the lifting stroke of the hydraulic cylinder 35 or the limitation of the vertical length of the lifting track 33, the height of the support adjustment system 1 and the mobile platform 2 as a whole may be limited. When the height of the arc door track 5 is high, the above lifting system 3 may not be implemented. Figures 13 - 16As shown in the figure, the provided lifting system 3 further includes a base 32, a lifting seat 34, and a connecting seat 36. The base 32 is disposed on the side of the elevated track 33 close to the corresponding cast-in-place concrete 7, and the base 32 is connected to the side surface of the corresponding cast-in-place concrete 7. Specifically, it is connected to the embedded part 31 within the cast-in-place concrete 7. The lifting seat 34, the hydraulic cylinder 35, and the connecting seat 36 are all disposed on the side of the elevated track 33 close to the column 11. The upper end of the hydraulic cylinder 35 is connected to the connecting seat 36, and the lower end is connected to the lifting seat 34. The base 32, the lifting seat 34, and the connecting seat 36 can all slide along the elevated track 33. In this embodiment, the elevated track 33 includes two vertically arranged and spaced-apart channel steels 331. The openings of the channel steels 331 face the upstream and downstream directions. A connection is formed between the two channel steels 331 by a horizontal first connecting plate 332. The first connecting plates 332 are arranged at intervals in the vertical direction. The base 32, the lifting seat 34, and the connecting seat 36 all have ear structures and can be slidably sleeved on the corresponding sides of the two channel steels 331 to achieve the sliding function. Moreover, the base 32, the lifting seat 34, and the connecting seat 36 can all be fixed to the elevated track 33. When the base 32 is fixed to the elevated track 33, the base 32 provides a fixed platform for it and prevents the elevated track 33 from falling downward. The connecting seat 36 is detachably connected to the corresponding base 32, and can be fixed by connecting a pin to a corresponding hole, such as Figure 16 As shown in the figure, on the upstream and downstream sides of the left side of the connecting seat 36 away from the column 11, there is respectively a second connecting plate 361. The two second connecting plates 361 on the upstream and downstream sides can be clamped on the outside of the base 32 and the elevated arc gate track 33. A fixed connection can be formed by sequentially passing a first pin 334 through the corresponding holes of the second connecting plate 361, the elevated track 33, and the second connecting plate 361 in the upstream and downstream directions. A fixed connection can be formed by sequentially passing a second pin 335 through the corresponding holes of the second connecting plate 361, the base 32, and the second connecting plate 361 in the upstream and downstream directions. The right side of the connecting seat 36 is used to connect the frame 21.

[0112] Before the hydraulic cylinder 35 jacks up, the lifting seat 34 and the base 32 are both fixed to the elevation track 33. The connecting seat 36 can slide upward on the elevation track 33. The hydraulic cylinder 35 jacks up the connecting seat 36, and the connecting seat 36 slides upward on the elevation track 33, driving the frame 21 to move upward. The frame 21 drives the column 11 to move upward, causing the support adjustment system 1 and the moving platform 2 to rise as a whole by one stroke. Fix the connecting seat 36 to the elevation track 33 or the base 32, release the fixation of the lifting seat 34 to the elevation track 33 so that the lifting seat 34 can slide along the elevation track 33, and then the lifting seat 34 can be lifted upward by one stroke with the connecting seat 36 as the fixed point and by retracting the hydraulic cylinder 35. Then fix the lifting seat 34 to the elevation track 33 again and make the connecting seat 36 able to slide upward on the elevation track 33, and the subsequent jacking can be continued. By adopting this cyclic method, the support adjustment system 1 and the moving platform 2 can be continuously lifted as a whole, and it is not limited by the jacking stroke of the hydraulic cylinder 35. The jacking height is the height of the elevation track 33, and the connecting seat 36 cannot exceed the top of the elevation track 33.

[0113] When the lifting seat 34 is at the top of the elevation track 33, the moving platform 2 cannot be jacked up continuously. Therefore, the elevation track 33 can be lifted. Before lifting the elevation track 33, fix the lifting seat 34 to the elevation track 33 and fix the connecting seat 36 to the corresponding base 32. The elevation track 33 can slide upward, and the elevation track 33 is lifted upward by one stroke by retracting the hydraulic cylinder 35. Then fix the elevation track 33 to the base 32 or the connecting seat 36, release the fixation of the lifting seat 34 to the elevation track 33, and the lifting seat 34 is jacked up by the hydraulic cylinder 35 to move downward along the elevation track 33 by one stroke. Then fix the lifting seat 34 to the elevation track 33 again, release the fixation of the elevation track 33 to the base 32 or the connecting seat 36, and the elevation track 33 can be lifted by one stroke again. By adopting this cyclic method, the elevation track 33 can be continuously lifted, and this lifting method is not limited by the jacking stroke of the hydraulic cylinder 35. The lifting height is the height of the elevation track 33.

[0114] By adopting the above cyclic jacking and lifting methods, the overall elevation of the support adjustment system 1 and the moving platform 2 is not limited by the jacking stroke of the hydraulic cylinder 35 and the length of the elevation track 33, with higher applicability, convenient operation and safe use. In this embodiment, as Figure 14As shown in the figure, on the side of the bottom of the channel steel 331 away from the base 32, strip holes 333 are provided at intervals in the vertical direction. When a pin is inserted into the strip holes 333, it can play a secondary safety protection role for the lifting seat 34 and the connecting seat 36 in case of failure when the support adjustment system 1 and the moving platform 2 are lifted. When the lifting track 33 climbs, it can prevent the lifting seat 34 from failing and the track from falling (secondary protection). That is, double protection for the entire lifting system 3. As Figure 9 As shown in the figure, the above-mentioned lifting systems 3 are respectively provided at both ends of the moving platform 2 in the Y direction. The frame 21 is of a rectangular structure. At two corners of the side of the frame 21 close to the cast-in-place concrete 7, through grooves 26 are respectively provided. The through grooves 26 are open towards the cast-in-place concrete 7. The lifting track 33 passes through the through grooves 26. Arranging the lifting system 3 at the through grooves 26 at the corners at both ends of the moving platform 2 in the Y direction can make the lifting process more stable and safe, and will not affect the upstream and downstream movement of the support adjustment system 1 on the moving platform 2. And the through grooves 26 can guide the upward movement of the lifting track 33.

[0115] In this embodiment, as Figure 2 As shown in the figure, a gate groove formwork 4 can also be provided on the column 11. One side of the gate groove formwork 4 is close to one side of the column 11, and the side of the gate groove formwork 4 close to the concrete side is the arc gate track 5. That is, as Figure 5 As shown in the figure, the gate groove formwork 4 is arranged between the column 11 and the corresponding arc gate track 5. The gate groove formwork 4 is provided with through holes 45 in the X direction. The support positioning mechanism 14 passes through the through holes 45 to support the corresponding arc gate track 5. The gate groove formwork 4 is the side formwork of the gate chamber on the side of the arc gate. It is arranged between the column 11 and the corresponding arc gate track 5 to realize the pouring support for the concrete on both sides of the arc gate track 5 in the upstream and downstream directions. The support positioning mechanism 14 passes through the through holes 45 on the gate groove formwork 4 to support the corresponding arc gate track 5, so that the arc gate track 5 can be supported and positioned by the support positioning mechanism 14 on the support adjustment system 1 to resist the lateral stress of the concrete pouring at the arc gate track 5 and ensure the accuracy of the arc gate track 5 after the concrete is poured. The length of the gate groove formwork 4 in the Y direction can be greater than or equal to the length of the arc gate track 5 in the Y direction, so that its length in the upstream and downstream directions is greater than or equal to the length of the arc gate track 5 in the upstream and downstream directions, which can cover the entire arc gate track 5 and reduce the deployment of the gate groove formwork 4.

[0116] When a number of rows of the through holes 45 are vertically distributed on the gate groove formwork 4, the directions of all rows of the through holes 45 are adapted to the radian of the arc gate track 5. In this way, without raising the gate groove formwork 4, it can adapt to the concrete pouring of a higher arc gate track 5, or the construction of the arc gate track 5 can be carried out in multiple times vertically. As Figure 17As shown, there are three rows of through holes 45 vertically distributed on the gate slot formwork 4, and the directions of the three rows of all the through holes 45 are adapted to the radian of the radial gate track 5, and the height can be constructed in three times.

[0117] Before pouring the concrete, the gate slot formwork 4 can also be supported on the mobile platform 2 through the adjusting rod 44, which can ensure the verticality of the gate slot formwork 4. After the poured concrete is formed, by shortening the supporting length of the adjusting rod 44, the gate slot formwork 4 can be separated from the concrete. As Figure 17 shown, several adjusting rods 44 are provided on the side of the gate slot formwork 4 close to the column 11. The adjusting rods 44 are distributed along the length direction of the gate slot formwork 4. The adjusting rods 44 are inclined. One end of the adjusting rod 44 is connected to the mobile platform 2 and the other end is fixed to the gate slot formwork 4. The adjusting rod 44 can adjust its supporting length, that is, the gate slot formwork 4 is higher than the mobile platform 2.

[0118] On the side of the gate slot formwork 4 close to the radial gate track 5, the gate slot formwork 4 can be connected to the top surface or the bottom sill 6 of the already poured concrete 7 through the tie bars 42, which can offset the lateral stress on the gate slot formwork 4 when pouring the concrete. As Figures 18 - 19 shown, several tie bars 42 are provided on the side of the gate slot formwork 4 close to the radial gate track 5. The tie bars 42 are misaligned with the radial gate track 5. One end of the tie bar 42 is connected to the gate slot formwork 4 and the other end is connected to the top surface or the bottom sill 6 of the already poured concrete 7, as Figure 20 shown.

[0119] In this embodiment, the adjusting rods 44 and the tie bars 42 are located on both sides of the gate slot formwork 4, but the functions of the adjusting rods 44 and the tie bars 42 are different. The tie bars 42 are connected to the top surface or the bottom sill 6 of the already poured concrete 7 to offset the lateral stress on the gate slot formwork 4 when pouring the concrete, and support the concrete when pouring the concrete to ensure the gate size; the adjusting rods 44 are used to ensure the verticality of the gate slot formwork 4 during installation and subsequent demoulding, and make the formwork surface quickly separate from the concrete during demoulding; the two do not interfere with each other, avoiding the influence of the concrete lateral stress on the mobile platform 2 and the support adjustment system 1. And a fixing seat 43 is provided at the bottom of the gate slot formwork 4. The fixing seat 43 can fix the gate slot formwork 4 on the mobile platform 2, can adjust the size of the bottom of the gate slot formwork 4, and can also demould quickly. When the mobile platform 2 and the support adjustment system 1 need to rise as a whole, the gate slot formwork 4 can also rise together after demoulding.

[0120] The gate slot construction device of the radial gate adopting this solution, the support and adjustment system 1 installs and adjusts and supports the radial gate track 5 to ensure the installation accuracy of the radial gate track 5. The mobile platform 2 is installed on the lifting system 3, the support and adjustment system 1 is installed on the mobile platform 2, the lifting system 3 raises the mobile platform 2 and then raises the support and adjustment system 1. The support and adjustment system 1 can move in the upstream and downstream directions on the mobile platform 2, so as to adapt to the trend of the radial gate track 5. The gate slot formwork 4 is installed on the mobile platform 2 and is used to support the orifice concrete during pouring. It can support and position different heights and different upstream and downstream position parts of the radial gate track 5, and can ensure the installation and post-construction accuracy of the radial gate track 5, so that the gate slot of the radial gate and the corresponding concrete pouring can be directly constructed in one stage. Compared with the second-stage construction, its construction period is shorter, the construction quality is better, and the safety is higher. And a control system can also be set in the support and adjustment system 1 to control the upstream and downstream movement, vertical lifting, other electrical appliances, etc. of the entire gate slot construction device of the radial gate.

[0121] Embodiment 2

[0122] This embodiment provides a gate slot construction device for a radial gate, which is different from the gate slot construction device for a radial gate in Embodiment 1 in that, see Figures 26 - 30 , the support and adjustment system 1 includes columns 11 on both sides in the X direction, the X direction is the width direction of the radial gate, the columns 11 are arranged vertically, and the tops of the two columns 11 on both sides are connected by a cross beam 12. The cross beam 12 can ensure that the top spacing of the two columns 11 on both sides remains unchanged. There is a pouring space for the pier located in the middle in the X direction between the two columns 11 on both sides and below the cross beam 12. The two columns 11 on both sides are respectively arranged in the to-be-constructed gate slots of the radial gates on both sides of the same pier.

[0123] The gate slot construction device of the radial gate in this embodiment is mainly used for the construction of the pier with gate slots of radial gates on both opposite sides in the X direction. During construction, it straddles the already poured concrete 7, as Figure 30 shown. Therefore, the radial gate tracks 5 on both sides in the X direction are located between the two columns 11. Correspondingly, the support and positioning mechanism 14 is also arranged on the opposite surfaces of the two columns 11. The other components such as the mobile platform 2, the lifting track 3, and the gate slot formwork 4 are the same as those in Embodiment 1.

[0124] Embodiment 3

[0125] This embodiment provides a gate slot construction device for a radial gate, which is different from the gate slot construction device for a radial gate in Embodiment 1 or Embodiment 2 in that, see Figures 31 - 32 , the support and adjustment system 1 includes a column 11 in the X direction, the X direction is the width direction of the radial gate, the column 11 is arranged vertically, and the column 11 is correspondingly arranged in the to-be-constructed gate slot of the side pier.

[0126] The gate slot construction device of the radial gate in this embodiment is mainly used for the construction of the side piers. Since there is only one gate slot on one side in the X direction of the side piers, there is only one column 11 and only one moving platform 2, as Figure 31 shown. The other components such as the moving platform 2, the lifting track 3, and the gate slot formwork 4 are the same as those in Embodiment 1.

[0127] Embodiment 4

[0128] This embodiment provides a method for constructing the gate slot of a radial gate. The gate slot of the radial gate is constructed by using the gate slot construction device of the radial gate described in any one of Embodiments 1, 2, and 3. Refer to Figure 33 , including the construction of the gate slot of the radial gate before the support adjustment system 1 is raised and the construction of the gate slot of the radial gate when the support adjustment system 1 needs to be raised; as Figure 20 shown, it is the construction state before the support adjustment system 1 is raised (for reference, while constructing the gate slots on both sides in the X direction, each gate slot corresponds to a pier or a side pier), as Figure 23 shown, it is the construction state of the gate slot of the radial gate when the support adjustment system 1 needs to be raised. The lifting system 3 and the moving platform 2 have been installed before the support adjustment system 1 is raised.

[0129] The construction of the gate slot of the radial gate before the support adjustment system 1 is raised includes steps S01 - S07: S01. Install the bottom sill 6 of the gate slot of the radial gate and pour the concrete of the gate slot to the elevation of the bottom sill 6, which can refer to Figure 20 the horizontal part of the bottom sill 6.

[0130] S02. Measure and set out the positions for installing the radial gate track 5, the support adjustment system 1, and the gate slot formwork 4. Install the support adjustment system 1, the gate slot formwork 4, and the first layer of the radial gate track 5 to be constructed according to the measurement and setting out, so that the gate slot formwork 4 is located between the column 11 of the support adjustment system 1 and the corresponding radial gate track 5 to be constructed. Then, support and position the radial gate track 5 by passing the strut of the support positioning mechanism 14 through the through - hole 45 on the gate slot formwork 4; the position of the support adjustment system 1 is determined according to the position of the radial gate track 5. The function of the support adjustment system 1 is to ensure the accuracy of the radial gate track 5. The gate slot formwork 4 is the concrete formwork for the part corresponding to the radial gate track 5 and is used for closing the formwork and pouring concrete, and its size can be selected. In this embodiment, the radial gate track 5 is supported and positioned by passing the strut of the support positioning mechanism 14 through the through - hole 45 on the gate slot formwork 4, and the gate slot formwork 4 used is a whole plate and can be lifted as a whole. Of course, it is also possible to use assembled formwork such as assembled wooden formwork at or around the radial gate track 5, leaving the position at the radial gate track 5, but this makes the assembly of the formwork difficult and reduces the overall construction efficiency.

[0131] S03. Connect templates on the basis of the gate slot formwork 4 to form the pouring space for the first layer of pier or abutment, and then pour the first layer of concrete;

[0132] S04. After the concrete of the upper layer reaches the design strength, if the height of the poured concrete 7 is less than H, where H is the maximum height after the installation of the lifting system 3 and the mobile platform 2, retract the struts of the support positioning mechanism 14, release the fixation of the support adjustment system 1, move the support adjustment system 1 along the Y direction to a predetermined position suitable for the next layer of the arc gate track 5 to be constructed and fix it, and then proceed to step S05; if the height of the poured concrete 7 is greater than or equal to H, enter the construction stage of the gate slot of the arc gate when the support adjustment system 1 needs to be raised; H can refer to Figure 23 the overall height of the lifting system 3 and the mobile platform 2, with the support adjustment system 1 on the bottom sill 6 as the reference, aiming to enable the space below the support adjustment system 1 corresponding to the next layer of the gate slot formwork 4 to install the lifting system 3 and the mobile platform 2;

[0133] S05. Install the gate slot formwork 4 and the arc gate track 5 to be constructed in the current layer, so that the gate slot formwork 4 is located between the columns 11 of the support adjustment system 1 and the arc gate track 5 to be constructed, and then support and position the arc gate track 5 by passing the struts of the support positioning mechanism 14 through the through holes 45 on the gate slot formwork 4; for the subsequent installation of the gate slot formwork 4, generally after the concrete of the upper layer reaches the design strength, after the formwork of the gate slot formwork 4 poured in the upper layer is demolded, move it to the corresponding position of the arc gate track 5 to be constructed in the current layer through lifting, lateral movement and other moving methods.

[0134] S06. Connect templates on the basis of the gate slot formwork 4 to form the pouring space for the pier or abutment in the current layer, and then pour the concrete in the current layer;

[0135] S07. Repeat step S04;

[0136] The construction steps of the gate slot of the arc gate when the support adjustment system 1 needs to be raised include S1 - S6:

[0137] S1. Release the fixed support of the support adjustment system 1 for the arc gate track 5 constructed in the upper layer;

[0138] S2. Install the mobile platform 2 and the lifting system 3, so that under the condition that the support adjustment system 1 is released from fixation, the support adjustment system 1 can move upstream along the mobile platform 2, and the lifting system 3 can raise the mobile platform 2 and the support adjustment system 1 as a whole;

[0139] S3. Release the fixation of the support adjustment system 1 to ensure that there is no interference when the support adjustment system 1 moves upward. Then, use the lifting system 3 to move the support adjustment system 1 and the mobile platform 2 upward as a whole to the corresponding support height of the unconstructed arc gate track 5 on the next lower layer. And release the fixation of the support adjustment system 1 to ensure that there is no interference when the support adjustment system 1 moves in the Y direction. Through the mobile platform 2, move the support adjustment system 1 in the Y direction to the corresponding support Y-direction position of the unconstructed arc gate track 5 on the next lower layer;

[0140] S4.

[0143] In the above solution, the single - lift of the support adjustment system can be adapted to the construction of the arc gate tracks to be constructed on multiple layers. Specifically, replace step S6 with S6': After the concrete on the upper layer reaches the design strength,

[0144] If the support height of the arc gate track 5 to be constructed on the next lower layer is still within the height range of the support adjustment system 1: Then release the fixation of the support adjustment system 1 to ensure that there is no interference when the support adjustment system 1 moves in the Y direction; Then, through the mobile platform 2, move the support adjustment system 1 in the Y direction to the corresponding support Y - direction position of the unconstructed arc gate track 5 on the next lower layer; Then fix the support adjustment system 1; Then install the gate slot formwork 4 and the arc gate track 5 to be constructed on the current layer, so that the gate slot formwork 4 is located between the columns 11 of the support adjustment system 1 and the corresponding arc gate track 5 to be constructed; Then, pass the strut of the support positioning mechanism 14 through the through hole 45 on the gate slot formwork 4 to support and position the arc gate track 5; Then, on the basis of the gate slot formwork 4, connect formworks to form the pouring space for the pier or side pier on the current layer, and then pour the concrete on the current layer; Then repeat step S6' until the construction of the gate slot of the arc gate is completed;

[0145] If the support height of the arc gate track 5 to be constructed on the next lower layer is above the height range of the support adjustment system 1: Then repeat steps S3 - S6' until the construction of the gate slot of the arc gate is completed.

[0146] In this embodiment, step S2 can also be carried out between steps S05 and S06 in the construction of the already constructed arc gate track 5 of the previous layer that the support adjustment system 1 needs to be raised.

[0147] Specifically, taking the method of constructing the gate slot of the arc gate by the gate slot construction device of the arc gate in Embodiment 1 as an example, when constructing the gate slot of the arc gate, it is divided into the construction before lifting and the cyclic construction that needs to be lifted subsequently:

[0148] See Figures 20 - 22 , the construction before lifting is as follows:

[0149] (1) Install the bottom sill 6 of the gate slot of the arc gate and pour concrete.

[0150] (2) When the concrete is just poured, install the inserted bars 71 on the side of the orifice according to the regulations.

[0151] (3) After measuring and setting out the lines to determine the installation positions of the arc gate track 5, the support adjustment system 1, and the gate slot formwork 4, hoist the support adjustment system 1 into the installation position, and use a steel wire to check the verticality or inclination of the columns 11 on both sides (X direction) of the support adjustment system 1, which meets the requirements of the design and specifications. Fix the support adjustment system 1 stably and reliably on the bottom sill 6.

[0152] (4) Hoist the first section of the arc gate track 5, accurately adjust the bottom position of the arc gate track 5 according to the measurement and setting out of the lines, accurately adjust the verticality and flatness of the arc gate track 5 by using the support positioning mechanism 14 on the support adjustment system 1, measure the position accuracy by using a theodolite, and weld it to the bottom sill 6 after adjustment. The distance between the left and right arc gate tracks 5 is the designed width of the gate slot. Tighten the remaining support adjustment system 1 against the arc gate track 5 to limit the negative deviation during concrete pouring, and weld and reinforce the steel bars on the non-working surface.

[0153] (5) Hoist the gate slot formwork 4. During the hoisting process, avoid colliding with the already installed arc gate track 5, and adjust the bottom according to the measurement and setting out of the lines. Then use the tie bars 42 to adjust the verticality of the gate slot formwork 4 and weld it to the inserted bars 71 to completely fix the gate slot formwork 4.

[0154] (6) Install the embedded parts 31 on the gate slot formwork 4. The installation position of the embedded parts 31 should correspond to the position of the subsequent elevated track 33.

[0158] (10) After the concrete reaches the strength requirement, the formwork 4 of the gate slot shall be removed from the form.

[0159] (11) When the following condition A is met (A. the pouring height of the poured concrete 7 is less than 6 m, and the support adjustment system 1 cannot support the arc gate track 5 within the pouring elevation range at the existing position), the support adjustment system 1 needs to be moved upstream. At this time, the support positioning mechanism 14 on the support adjustment system 1 shall be loosened, and the connection between the support adjustment system 1 and the already installed arc gate track 5 shall be released. And it shall be moved upstream to an appropriate position on the ground in the flow channel, and the arc gate track 5 to be poured shall be adjusted and fixed.

[0160] (12) Install the formwork 4 of the gate slot and adjust and fix it.

[0168] 3) Use the embedded parts 31 installed during the pouring of the previous bay to install the lifting system 3, the moving platform 2, and the fixing seats 43 and adjusting rods 44 on the formwork 4 of the gate slot.

[0169] 4) Debug the moving parts of the moving platform 2 and the lifting system 3; the moving parts of the moving platform 2, such as the moving device 23, the rolling frame 24, etc.; the moving parts of the lifting system 3, such as the hydraulic cylinder 35, etc.

[0170] 5) After the debugging is completed, connect the support adjustment system 1 to the mobile platform 2, and adjust the verticality of the support adjustment system 1 in the upstream-downstream direction and the left-right bank direction to meet the design requirements.

[0175] (3) Overall lifting of the support adjustment system 1 and the mobile platform 2

[0176] 1) When the poured concrete reaches the strength requirement, use the fixed seat 43 and the adjusting rod 44 on the gate slot formwork 4 for demoulding, so that it is separated from the concrete and maintains a gap of 10 - 20 mm, and release the connection between them (except for the first lift, because in the first time (the first bin), the gate slot formwork 4 uses the traditional demoulding method, and the fixed seat 43 and the adjusting rod 44 are not installed on the formwork yet. The fixed seat 43 and the adjusting rod 44 are only installed together after the mobile platform 2 is installed.).

[0177] 2) Release the fixation of the support adjustment system 1 with the radial gate track 5 and other components of the gate slot, and the support adjustment system 1 and the mobile platform 2 still remain in a fixed state.
