Description
Technical Field
[0001] The present invention relates to the technical field of navigation and power hub construction, and in particular to a navigation and power hub ship lock and channel structure and a construction method thereof. Background Art
[0002] With the rapid development of my country's economy, the importance of inland waterway shipping in the field of cargo transportation has become increasingly prominent, and the construction of a large number of inland waterway navigation and power hub projects is also in full swing. During the construction of navigation and power hub projects, the ship lock is the most important component structure. It is mainly used to ensure the smooth passage of ships in the channel. It is a box-shaped hydraulic structure that concentrates the water level difference on the channel. The ship lock consists of an upstream pilot channel, a downstream pilot channel and a lock chamber. During the design and construction of the ship lock, it is necessary to consider the following factors:
[0003] 1. The lock channel structure is located at the bottom of the inland river. Its foundation structure is related to the safety of the entire lock structure. Therefore, the lock foundation structure is a factor that needs to be considered;
[0004] Second, the structure of the lock channel is not only related to the structural stability and safety, but also needs to adapt to the changes and activities of the water flow, which plays a very important role in ensuring the life of the lock;
[0005] 3. The ship lock channel structure is large in size. How to ensure the construction efficiency and quality during the construction process is also an aspect that needs to be considered during the ship lock construction process;
[0006] 4. The lock and channel structure needs to ensure sufficient navigation capacity for ships and navigation safety when ships pass through the channel.
[0007] Therefore, what structural form of the lock and channel structure to adopt and how to construct it are major technical issues faced during the design and construction of the navigation and power hub project. Summary of the Invention
[0008] At least one of the purposes of the present invention is to provide a navigation and power hub lock structure, which can ensure the stability and reliability of the channel piers and will not be affected by the water flow, and has strong navigation capacity, so as to address the problems that the existing lock and channel structures have unreasonable structural designs during the construction of existing navigation and power hubs, cannot effectively ensure structural safety, and have poor navigation capacity.
[0009] In order to achieve the above objectives, the technical solutions adopted by the present invention include the following aspects.
[0010] A navigation and power hub ship lock channel structure includes a left pier and a right pier, wherein the left pier is arranged on the side close to the center of the river, and the right pier is arranged on the side close to the shore. The left pier and the right pier are arranged side by side to form a channel in the middle. The left pier consists of a left pier foundation, a left pier base and a left pier wall of an integral structure from the bottom to the top, and the right pier consists of a right pier foundation, a right pier base and a right pier wall of an integral structure from the bottom to the top. The width gradually decreases from the bottom upwards, and the bottoms of the left pier foundation and the right pier foundation are both provided with anchor rods anchored in the river channel strata. The left pier wall includes a left wall portion of the channel located on the side of the right pier, and the right pier wall includes a right wall portion of the channel located on the side of the left pier. Both the left wall portion and the right wall portion of the channel are vertical structures, and the height of the left wall portion of the channel is 65% to 80% of the overall height of the left pier, and the height of the right wall portion of the channel is 65% to 80% of the overall height of the right pier.
[0011] This scheme adopts the method of setting anchor rods at the bottom of the left pier foundation and the right pier foundation, and anchoring the anchor rods in the river stratum, so that the piers on both sides of the channel structure form a more closely connected integral structure with the river stratum, ensuring the safety of the lock channel foundation structure. In addition, the piers on both sides adopt an integral structure with a width gradually decreasing from the bottom to the top. While ensuring the safety of the channel structure, the amount of concrete used in the piers is reduced and the construction cost is reduced. At the same time, the structural size of the upper part of the pier is smaller, which can reduce the water flow resistance and increase the service life of the ship lock. In addition, the height of the left wall part and the right wall part of the channel respectively account for 65% to 80% of the overall height of the left pier and the overall height of the right pier, which can improve the navigation capacity of ships, ensure the safe navigation and lifting of ships in the channel, and avoid structural problems such as "reefs" that are easy to scratch the navigation of ships.
[0012] Preferably, the left pier base is connected to the left pier foundation, the bottom surface size of the left pier base corresponds to the top surface size of the left pier foundation, the left pier base shrinks from bottom to top, the left pier base includes a channel left base slope portion, a river channel side base slope portion and a channel left base vertical portion, the slope of the channel left base slope portion is smaller than the slope of the river channel side base slope portion, the channel left base vertical portion is arranged above the channel left base slope portion, and the two are smoothly connected to form an integral structure, the height of the left base slope portion is 1 / 2 to 2 / 3 of the height of the river channel side base slope portion, and the remaining height is the channel left base vertical portion, the height of the left pier base is between 4 and 7 meters, and the slope of the river channel side base slope portion is between 40% and 60%.
[0013] By adopting this structural form of the left pier base, the larger left pier foundation is transitioned to the smaller left pier wall, avoiding the left pier base occupying the bottom space of the channel, further ensuring the safety of the channel, and at the same time forming a wider channel between the left pier wall and the right pier wall.
[0014] Preferably, the left pier wall includes a left channel wall portion and a river channel wall slope portion. The left channel wall portion is flush with the surface of the vertical portion of the left channel base, and both are vertical structures. The river channel side wall slope portion is smoothly connected to the river channel side base slope portion, and the slope of the river channel side wall slope portion is between 60% and 80%.
[0015] The left pier wall adopts this structural form. On the one hand, it can ensure structural stability. The structural form of the left pier wall gradually reduces in size from bottom to top, which can adapt to changes in water flow and reduce water resistance. On the other hand, it can prevent ships from touching the lock channel structure and causing damage when they have a large draft.
[0016] Preferably, the right side pier base includes a channel right side base slope portion and a shore side base slope portion, the slope of the channel right side base slope portion is smaller than the slope of the shore side base slope portion, and a shore side base horizontal section is further provided at the bottom of the shore side base slope portion, the shore side base slope portion is connected to the left side of the shore side base horizontal section, and the right side of the shore side base horizontal section is vertically arranged as an integral part of the right side pier foundation, the height of the channel right side base slope portion is between 3 and 5 meters, and the slope is between 35% and 50%.
[0017] The right pier base adopts this structural form, and the larger right pier foundation is transitioned to the smaller right pier wall, so as to avoid the right pier base occupying the bottom space of the waterway channel, and further ensure the safety of the waterway channel; the setting of the horizontal section of the shore side base can increase the vertical gravity load of the shore side soil and rocks on the pier foundation, further improve the structural stability of the right pier, and ensure the safety of the right pier.
[0018] Preferably, the right pier wall includes a channel right wall portion and a bank side wall slope portion, the channel right wall portion is smoothly connected to the channel right base slope portion, the channel right wall portion is a vertical structure, and the bank side wall slope portion is a continuation of the bank side base slope portion, the two have the same slope and are an integrated continuous structure with a slope of between 40% and 60%. The right pier wall with this structural form, on the one hand, forms a wider channel between the right pier wall and the left pier wall, ensuring the safety of ships passing through the lock, and on the other hand, the bank side wall slope portion is an integrated continuous structure with the bank side base slope portion, which can improve the stability of the right pier structure, thereby withstanding the greater soil pressure on the shore, further ensuring the safety of the right pier structure.
[0019] Preferably, the navigation and power hub ship lock channel structure also includes a left pier top arranged on the top of the left pier wall, and a right pier top arranged on the top of the right pier wall, the left pier top and the right pier top are both rectangular structures, and the left pier top and the right pier top are located on one side of the channel and are flush with the left wall portion and the right wall portion of the channel respectively, and the left pier foundation and the right pier foundation are embedded below the bottom surface of the river channel.
[0020] By embedding the foundations of the left and right piers below the bottom surface of the river channel, the pier foundations are covered with pebbles or river soil and gravel, thereby preventing the pier foundations from being eroded by water flow, further ensuring the safety of the pier structure, and setting a rectangular pier top on the top of the pier wall, including the left pier top and the right pier top, and the left pier top and the right pier top are located on one side of the channel and are flush with the left wall part and the right wall part of the channel respectively, which can further increase the height of the channel.
[0021] Correspondingly, the present application also provides a template system for constructing the lock and channel structure of the navigation and power hub. Since the structures of the left pier and the right pier are similar, the same template system is used for construction of both. The structure of the lock and channel template system of the navigation and power hub is explained by taking the casting construction of the right pier as an example. Since the right pier is high and long, it is necessary to cast the right pier from the bottom up in sequence, including the right pier foundation, the right pier base and the right pier wall. According to the height of each component in the right pier foundation, the right pier base and the right pier wall, the right pier foundation, the right pier base and the right pier wall are cast in rounds as needed, and the casting is carried out in layers during each round of casting.
[0022] The navigation and power hub ship lock channel template system mainly includes a template subsystem, a triangular support subsystem, an embedded part subsystem and a top working platform. The template subsystem is used to be installed at the location where concrete is to be poured. The embedded subsystem is used to install and fix the triangular support subsystem and the template subsystem. The triangular support subsystem is used to support and fix the template subsystem, so that the template subsystem can resist the lateral pressure of pouring concrete under the support of the embedded subsystem and the triangular support subsystem. Among them, the template subsystem includes a pouring panel, a back rib and a support skeleton. The back rib is connected to the back of the pouring panel, including a transverse back rib and a longitudinal back rib.

The sliding beams slide on the supporting beams. On the side close to the formwork subsystem, positioning pin holes are provided on the sliding beams and the supporting beams. After adjusting the formwork subsystem into place through the sliding beams, the pins are inserted to fix the sliding beams and the supporting beams. When the supporting frame and the diagonal braces are directly connected to the supporting beams, the supporting frame and the diagonal braces can also be connected to the supporting beams through sliding supports and sliders respectively. On the supporting beam, the embedded part subsystem includes a plurality of connecting embedded parts for being embedded in each round of concrete pouring, the connecting embedded parts are used to be embedded in the concrete, and are used to install and fix the formwork subsystem and the triangular support subsystem, the connecting embedded parts include a fixing part embedded in the concrete, the fixing part is a conical structure with a flange, and also includes a connecting part connected to the fixing part, the connecting part and the fixing part are connected by a screw, the connecting part is also a conical structure, the screw can extend out of the connecting part for fixing to the supporting frame, and can also be connected to the end of the connecting part, and then an internal thread is arranged on the connecting part near one end of the formwork subsystem, and the screw is fixed to the supporting frame by installing the screw on the internal thread. When fixing the supporting frame and the supporting beam, The embedded part subsystem is connected to the internal thread of the connecting part by a screw or bolt. The embedded part subsystem also includes a supporting clamp installed on the connecting embedded part. The supporting beam is also connected to the supporting frame at one end with a mounting ear seat. The supporting clamp is provided with a slot for engaging the mounting ear seat. A screw hole is provided in the middle of the supporting clamp, which is fixed to the screw through the screw hole. The mounting ear seat includes an end plate and a reinforcing connecting plate. A U-shaped groove is provided on one end plate of the supporting clamp for engaging with the supporting clamp. After the supporting clamp is installed on the screw connecting the embedded part, the slot on the outside of the supporting clamp is used to support the mounting ear seat. The mounting ear seat is engaged with the supporting clamp by hoisting the overall structure including the template subsystem and the triangular support subsystem, thereby realizing the installation of the triangular support subsystem.
[0023] The support rail is fixedly mounted on the support rail, and the support rail is fixedly mounted on the support rail, wherein the support rail comprises a first support rail, a second support rail and a second support rail, wherein the first support rail and the second support rail are connected at one end to the support rail and the other end to the support rail, forming a triangular support structure for supporting the support rail. The top platform is provided with an anti-slip pad, and the setting of a hanging platform can solve the problem of construction workers' rest during the pouring process at high altitudes; the ship lock channel formwork system also includes a top working platform, which is used as a pouring construction platform for each layer of concrete, and the top working platform is installed on the upper side of the supporting frame near the part to be poured concrete, and the top working platform includes an upper platform vertically connected to the supporting frame, and a panel is set on the upper platform to form a pouring work platform. The top working platform also includes a top supporting frame for supporting the upper platform and a guardrail arranged on the outside of the upper platform.

[0024] The lock channel formwork system of this solution can be disassembled and loosened as a whole and hoisted to the upper layer of concrete to be poured during the pouring of each right-side pier. It does not need to be erected separately, which greatly improves construction efficiency.
[0025] This technical solution also provides a construction method for a navigation and power hub lock and channel structure. When the above-mentioned template system is used to construct the navigation and power hub lock and channel structure, the method includes pouring concrete on the left and right gate piers. When constructing the right gate pier, the main construction steps include:
[0026] Step A: Excavate the right gate pier construction area, install anchor rods after excavation is completed, and anchor the anchor rods into the riverbed stratum;
[0027] Step B: Arrange the formwork subsystem outside the right pier foundation. The formwork subsystem is first assembled on the assembly platform, including assembling the casting panel, back ribs and support frame. The casting panel is intermittently welded to the back ribs. The support frame is welded to the back ribs. A sling is fixed to the formwork subsystem. At the same time, a top working platform is installed on the support frame. The top working platform is connected to the support frame near the sling;
[0028] Step C: Tie the structural steel bars of the right gate pier foundation and embed connecting embedded parts in the structural steel bars. The connecting embedded parts are set in two rows on the upper part of the right gate pier foundation, and the upper row is about 500 to 800 mm away from the first round of concrete pouring on the right gate pier base;
[0029] Step D: Adjust and position the formwork subsystem, and set up a bottom support bracket supporting the formwork subsystem outside the formwork subsystem, and connect and fix the support frame to the connecting embedded parts. The bottom support bracket adopts a bent support structure or a diagonal brace combined with a reinforcement. One end of the reinforcement is fixedly connected to the upper end of the anchor rod at the part to be poured, and the other end passes through the pouring panel and is fixed to the support frame;
[0030] Step E: Use layered pouring to complete the pouring of the right gate pier foundation, with each layer pouring thickness between 400 and 600 mm;
[0031] Step F: After the poured right gate pier foundation reaches the designed strength, remove the bottom support bracket and hoist the pouring formwork subsystem together with the top working platform as a whole to the concrete part of the right gate pier base to be poured. Pour the concrete in multiple rounds according to the thickness of the right gate pier base, and pour the concrete in layers in each round. Before pouring, install the formwork subsystem and triangular support subsystem on the connecting embedded parts. At the same time, adjust and position the formwork subsystem, and install and fix the triangular support subsystem so that the triangular support subsystem supports the formwork subsystem. Then, carry out the first round of concrete pouring for the right gate pier base.
[0032] Step G: After the first round of concrete reaches the required strength, the connection between the formwork subsystem and the embedded parts is dismantled and loosened, as well as the connection between the triangular support subsystem and the embedded parts. The formwork subsystem and the triangular support subsystem are hoisted to the location where the subsequent round of concrete is to be poured.
[0033] Step H: After the concrete poured in the subsequent rounds in the gate pier base reaches the design strength, the connection between the formwork subsystem and the connecting embedded parts is dismantled and loosened, as well as the connection between the triangular support subsystem and the connecting embedded parts. The formwork system including the formwork subsystem, the triangular support subsystem and the top working platform is hoisted as a whole to the position of the right gate pier wall to be poured with concrete. The right gate pier wall is poured in multiple rounds. In the first round of pouring, the formwork subsystem and the triangular support subsystem are respectively installed and fixed on the connecting embedded parts embedded in the last round of poured concrete in the right gate pier base, and a lifting platform is installed on the triangular support frame. Then, the first round of concrete for the right gate pier wall is poured. Before pouring, the steel bars are tied and the connecting embedded parts are buried.
[0034] Step I: After the first round of concrete pouring on the right pier wall reaches the designed strength, dismantle and loosen the formwork system, lift the entire structure to the location where the second round of concrete pouring on the right pier wall is to be placed, position and secure the formwork system, bury the connecting embedded parts, and pour concrete. Repeat this process until all rounds of concrete pouring on the right pier wall are completed. Finally, pour the top of the right pier in the same way.
[0035] The construction method of the navigation and power hub ship lock channel structure also includes constructing the left gate pier. The left gate pier has a similar structure to the right gate pier. The casting construction of the left gate pier is carried out with reference to the above steps A to I.
[0036] The construction method of the navigation and power hub lock channel structure using this technical solution ensures that during the pouring of the left and right pier concrete, the formwork subsystem can provide stable support without problems such as displacement and mold expansion, ensuring that the formwork subsystem can resist the lateral pressure of the concrete and guaranteeing the pouring quality of the pier concrete.
[0037] In addition, the formwork system is used for the left and right gate piers. After pouring each part or each round of concrete, it is only necessary to loosen the formwork subsystem to achieve the overall upward movement of the formwork system, and it can be quickly installed through the embedded subsystem and triangular support subsystem, which greatly improves the construction efficiency of the formwork installation.
[0038] Preferably, the formwork subsystem is also provided with two layers of inclined rods. When pouring the right pier foundation, one end of the first layer of inclined rods is connected to the upper end of the anchor rod, and the other end is connected to the top end of the support frame. The bottom end of the second layer of inclined rods is also connected to the upper end of the anchor rod, and the other end passes through the pouring panel and is connected to the middle section of the support frame.
[0039] Furthermore, when pouring the base slope on the right side of the construction channel, the base slope on the shore side and the wall slope on the shore side, a support rod is also set on the template subsystem. The support rod is supported on the poured concrete and the other end is supported on the support frame or the pouring panel.
[0040] Preferably, when pouring the right side gate pier base in step F, the formwork subsystem is installed and removed for pouring in three rounds. The first round is to pour the bottom part of the slope of the right side base of the waterway and the horizontal section of the bank side base. The second round is to pour the middle part of the slope of the right side base of the waterway and the bottom part of the slope of the bank side base. The third round is to pour the remaining height of the gate pier base. After the first round of pouring is completed, the formwork system is moved to be installed and the second and third rounds are poured. Before pouring the first round, the connecting embedded parts are first installed in the first round of concrete to be poured. The connecting embedded parts are provided in two rows. The formwork subsystem is preliminarily connected to the upper row of connecting embedded parts embedded in the next layer of the right side gate pier foundation concrete that has been poured through the support frame. Then the triangular support subsystem is installed, and the supporting crossbeams of the triangular support subsystem are installed on the connecting embedded parts in the middle and lower rows of the gate pier foundation. During installation, the connecting embedded parts are first installed in the connecting embedded parts Install the support clamp ring on it, and then fix it with the mounting ear seat at the end of the supporting beam, connect the formwork subsystem with the supporting beam through the sliding beam, put the casting panel in place by adjusting the sliding beam, and finally fix the formwork subsystem on the upper row of connecting embedded parts in the right gate pier foundation through the supporting frame, insert the pins of the sliding beam and the supporting beam, fix the sliding beam and the supporting beam, and pour the bottom part of the slope of the right side base of the channel and the horizontal section of the shore side base concrete of the first round, and install the diagonal brace at the same time, and install a triangular support frame at the bottom of the supporting beam, the triangular support frame includes a vertical pole, an oblique rod and a column, one end of the vertical pole and the oblique rod is connected to the column, and the other end is respectively connected to the two ends of the supporting beam to form a triangular support structure, one end of the column is connected to the oblique rod, and the other end is provided with a support plate, and the column is supported on the concrete surface of the right gate pier foundation through the support plate;
[0041] Furthermore, when the formwork subsystem and the triangular support subsystem are hoisted to the location where the concrete is to be poured in the subsequent rounds in step G, the support frame and the support beam are installed and fixed on the pre-embedded connection parts embedded in the first round of concrete pouring of the right pier base, and the second and third rounds of concrete pouring of the pier base are carried out;
[0042] Furthermore, in step H, before pouring the first round of the right pier wall, the support frame and the support beam are respectively fixed to the pre-embedded connection parts in the third round of poured concrete in the right pier base.
[0043] In summary, due to the adoption of the above technical solution, the present invention has at least the following beneficial effects:
[0044] 1. The ship lock and channel structure of the navigation and power hub adopts this scheme. By setting anchor rods at the bottom of the left and right pier foundations and anchoring the anchor rods in the river stratum, the piers on both sides of the channel structure form an integral structure with a closer connection with the river stratum, thereby ensuring the safety of the ship lock and channel foundation structure. In addition, the piers on both sides adopt an integral structure with a width gradually decreasing from the bottom to the top. While ensuring the safety of the channel structure, the amount of pier concrete used is reduced, and the construction cost is reduced. At the same time, the structural size of the upper part of the pier is smaller, which can reduce water flow resistance and increase the service life of the ship lock. In addition, the height of the left wall part of the channel and the height of the right wall part of the channel are respectively 65% to 80% of the overall height of the left pier and the overall height of the right pier, which can improve the navigation capacity of ships, ensure the safe navigation and lifting of ships in the channel, and avoid structural problems such as "reefs" that are easy to scratch the navigation of ships.
[0045] 2. The formwork system of this technical solution is installed and fixed through the embedded subsystem. The embedded subsystem is installed when the formwork subsystem is pouring the previous layer of concrete. After the concrete pouring is completed and reaches the design strength, the triangular support subsystem and the connection between the formwork subsystem and the embedded subsystem are removed. By lifting the formwork subsystem and the triangular support subsystem, and installing the triangular support subsystem on the embedded subsystem of the previous layer, and fixing the formwork subsystem, the top working platform moves upward with the formwork subsystem, and the top working platform is used as a construction platform to pour the previous layer of concrete. This structural formwork system solves the problems of difficult erection and low construction efficiency of existing formwork structures, and greatly improves the efficiency of formwork installation and disassembly;
[0046] 3. The construction method of the ship lock and channel structure of the navigation and power hub adopting this scheme can solve the problems of long time and low efficiency in setting up formwork during the pouring of pier concrete in the ship lock and channel structure. After disassembly, the whole is hoisted to the upper layer and directly installed and fixed through support clamps. After adjusting the formwork subsystem into place, the formwork subsystem is fixed to the poured concrete structure through the support frame to ensure that the formwork is positioned and fixed, which greatly simplifies the installation method and improves the installation efficiency. At the same time, after the formwork subsystem and the triangular support subsystem are connected and fixed with the connecting embedded parts, the triangular support subsystem is supported by adjusting the position of the pouring panel to ensure accurate positioning of the formwork and the pouring quality.

When pouring the right side gate pier foundation 61, the connecting embedded parts 301 are installed on the upper part of the right side gate pier foundation 61. The connecting embedded parts 301 are pre-buried and fixed. After installing the formwork subsystem 1 and the triangular support subsystem 2, the support skeleton 103 is fixed on the connecting embedded parts 301. The connecting embedded parts 301 are arranged in two rows, upper and lower. After pouring the right side gate pier foundation 61, the right side gate pier base 62 is poured. The right side gate pier base 62 is poured in three rounds. The first round pours the bottom part of the slope part 621 of the right side base of the waterway and the horizontal section 623 of the shore side base.

Figure 6 and 7 As shown, a screw hole 3022 is provided in the middle of the support clamp 302, which is fixed to the screw rod 3013 through the screw hole 3022. The mounting ear seat 204 includes an end plate 2041 and a reinforcing connecting plate 2042. A U-shaped groove 2043 is provided on the end plate 2041 on one side for engaging with the support clamp 302. After the support clamp 302 is installed on the screw rod 3013 connected to the embedded part 301, the groove 3021 on the outside of the support clamp 302 is used to support the mounting ear seat 204. When pouring the second and third rounds of concrete for the right pier base 62, the mounting ear seat 204 is engaged with the support clamp 302 by hoisting the overall structure including the formwork subsystem 1 and the triangular support subsystem 2, thereby realizing the installation of the triangular support subsystem.
[0067] The triangular support subsystem 2 can either engage the mounting ear seat 204 on the slot 3021 of the support clamping ring 302, or directly engage it on the internal threaded screw 3013 of the connecting part 3012, and fix it by tightening the nut that cooperates with the screw 3013. Another embodiment also includes opening mounting holes on the end plates on both sides of the mounting ear seat 204, and fixing the screw 3013 on the embedded part 301 through the mounting holes.
[0068] As one of the preferred embodiments, the triangular support subsystem 2 also includes a triangular support frame 205 installed under the supporting beam 201, and a hanging platform 207 fixedly connected to the triangular support frame 205, the triangular support frame 205 includes a vertical pole 2051, an inclined rod 2052 and a column 2053, one end of the vertical pole 2051 and the inclined rod 2052 are connected to the column 2053, and the other end is respectively connected to the two ends of the supporting beam 201 to form a triangular support structure, one end of the column 2053 is connected to the vertical pole 2051 and the inclined rod 2052, and the other end is used to support the poured concrete 10 on the right side gate pier 6. The provision of the triangular support frame 205 can improve the supporting stability of the supporting beam 201, thereby ensuring that the template subsystem 1 is positioned stably and reliably, and the column 2053 is used to support the poured concrete. A support plate 2054 is provided at one end of the column 2053. By providing the support plate 2054, the triangular support frame 205 is stably supported on the poured concrete. When pouring the right gate pier foundation 61, the supporting crossbeam 201 is horizontally set on the foundation, and there is no need to set up a triangular support frame 205. When pouring the right gate pier base 62, the right gate pier wall 63 and the right gate pier top 64, the triangular support frame 205 is set. When pouring the second round of concrete of the right gate pier base 62 and the above parts, a hanging platform 207 is also set. The hanging platform 207 includes a first vertical rod 2071 and a second vertical rod 2072. The first vertical rod 2071 is connected to the vertical rod 2051, and the second vertical rod 2072 is connected to the diagonal rod 2052. The other ends of the first vertical rod 2071 and the second vertical rod 2072 are flush and connected by a cross rod 2073. An anti-slip pad 2074 is set on the cross rod 2073. By setting up the hanging platform, the problem of construction workers taking a rest during the high-altitude pouring process can be solved.
[0069] Since the concrete volume of the right gate pier 6 is large, during the pouring process, the formwork subsystem 1 is subjected to a large lateral force from the poured concrete. In order to improve the lateral pressure resistance of the formwork subsystem 1, two layers (rows) of diagonal rods 104 are also provided on the formwork subsystem 1. One end of the first layer (row) of diagonal rods 1041 is connected to the steel bar segment embedded in the concrete, and the other end is connected to the top end of the support skeleton 103. The bottom end of the second layer (row) of diagonal rods 1042 is also connected to the steel bar segment embedded in the concrete, and the other end passes through the pouring panel 101 and is connected to the middle section of the support skeleton 103. The provision of double layers (rows) of diagonal rods 104 can further improve the positioning accuracy of the pouring panel 101 and avoid affecting its positioning position during the pouring process.
[0070] Since the right side channel base slope 621, the bank side base slope 622 and the bank side wall slope 632 of the right side gate pier 6 are all inclined toward the side of the gate pier main body, the casting panel 101 of the template subsystem 1 is arranged inclined toward the side where the concrete is to be poured. As one of the preferred embodiments, Figure 8 and 9 As shown, the formwork subsystem 1 is further provided with a support rod 105 supported on the poured concrete 10, and the other end of the support rod 105 is supported on the support frame 103 or the pouring panel 101. The provision of the support rod 105 can improve the stability of the formwork subsystem. Before pouring 1 / 2 thickness of concrete in each round, the support rod 105 assists in supporting the pouring panel 101. After pouring half thickness of each layer of concrete, the support rod 105 can be removed or left permanently in the concrete. The pouring panel 101 is positioned by the poured thickness of concrete and other auxiliary methods. When the support rod 105 is supported on the pouring panel 101, it is necessary to set concrete pads or other embedded pads at the support position for later repair.
[0071] The lock channel formwork system of this scheme also includes a top-level working platform 4, which is used as a pouring construction platform for each layer of concrete. The top-level working platform 4 is installed on the upper side of the support frame 103 close to the part to be poured with concrete. The top-level working platform 4 includes an upper platform 401 vertically connected to the support frame 103. The upper platform adopts I-beams or channel steels. Panels are set up on the upper platform 401 to form a pouring work platform.

The top crossbeam 4021 and the top inclined beam 4022 are arranged at an angle. One end of the beam 4022 is connected, and the other end is connected to the back rib 102 respectively. The middle part of the top cross beam 4021 and the top oblique beam 4022 is also connected with a top vertical beam 4023. The top cross beam 4021, the top oblique beam 4022 and the top vertical beam 4023 are all made of angle steel.

When pouring the right pier foundation 61, one end of the first layer (row) of inclined rods 1041 is connected to the upper end of the anchor rod 8, and the other end is connected to the top end of the support frame 103. The bottom end of the second layer (row) of inclined rods 1042 is also connected to the upper end of the anchor rod 8, and the other end passes through the pouring panel 101 and is connected to the middle section of the support frame 103. A double layer (row) of inclined rods is provided. 104 can further improve the positioning accuracy of the casting panel 101, and avoid affecting its positioning position during the casting of the right gate pier 6; when constructing the right gate pier base 62 and the right gate pier wall 63, when pouring each round of concrete, a diagonal rod is also set to anchor the formwork subsystem. At this time, one end of the diagonal rod 104 is connected to the poured concrete, and the other end is directly or through the casting panel 101 and then fixed to the support frame 103. The way to connect to the poured concrete is to pre-embed a steel bar segment in the next layer of concrete to be poured, and connect the diagonal rod to the embedded steel bar segment, or connect the diagonal rod 104 to the structural steel bar.

The support rod 105 is supported on the poured concrete 10, and the other end is supported on the support skeleton 103 or the pouring panel 101. The support rod 105 can improve the stability of the template subsystem, and the two wheels of concrete mortar 10 are used to pour the right side gate pier foundation 61 and the right side gate pier base 62. When pouring five rounds of concrete on the soil and the right pier wall 63, before pouring 1 / 2 thickness of the concrete, the support rod 105 can assist in supporting the pouring panel 101. After pouring half thickness of the concrete, the support rod 105 can be removed or left permanently in the concrete, and the pouring panel 101 can be positioned by the poured thickness of concrete and other auxiliary methods. When the support rod 105 is supported on the pouring panel 101, concrete pads or other embedded pads need to be set at the supporting position for later repair.
