Description

Technical Field

[0001] The present invention relates to the technical field of underwater construction, and in particular to an underwater working platform for a waterstop and an underwater installation method. Background Art

[0002] Prefabricated box culverts are standardized box-shaped components prefabricated by manufacturers. After installation, welding, assembly and other processes, they can be flexibly combined into culvert structures of different sizes, lengths and cross-sectional shapes. They can be widely used in drainage systems in water conservancy projects and transportation projects. In the prior art, waterstops are arranged between adjacent prefabricated box culverts. The waterstops can fit well with the inner wall of the prefabricated box culvert, thereby effectively preventing water seepage and improving the sealing of the culvert.

[0003] In underwater projects, the installation of waterstops on prefabricated box culverts must be carried out underwater, that is, the installation of waterstops requires professional divers to operate. Divers first need to spread the waterstops underwater and use pressure plates to press the waterstops against the inner wall of the box culvert. Then, due to the large length of the waterstops, the smooth spreading underwater requires the coordinated operation of multiple divers, which not only increases the difficulty of construction, but also increases the construction cost. In addition, the pressure plate is made of metal throughout the entire length and is heavy. It is difficult for divers to stably lift the pressure plate underwater and accurately align the bolts through the pressure plate to the reserved holes on the box culvert. At the same time, the internal space of the culvert is large, and divers lack a suitable fulcrum when working underwater, which further increases the difficulty of the operation and limits the feasibility of divers working for a long time.

[0054] Embodiment 1

[0055] like Figures 1 to 9 As shown, this embodiment provides an underwater working platform for the waterstop 300, which reduces the difficulty of underwater installation of the waterstop 300, improves the efficiency of underwater installation of the waterstop 300, and ensures the safety of divers' underwater operations.

[0056] See also Figure 1 , Figure 2 and Figure 3, a plurality of pressure plates 100 are arranged at intervals along the circumference of the box culvert 200, and the pressure plates 100 are used to press the water stop 300 against the inner wall of the box culvert 200. The underwater working platform for the water stop 300 includes a bracket 1, a plurality of first supporting seats 2 and a plurality of second supporting seats 3. The bracket 1 can be installed in the culvert 201 of the box culvert 200; the plurality of first supporting seats 2 are movably arranged on the bracket 1 along the pressing direction, and the plurality of first supporting seats 2 are arranged at intervals along the circumference of the bracket 1, and the water stop 300 can be laid on the plurality of first supporting seats along the circumference of the bracket 1 2, driving the first support seat 2 to move, the first support seat 2 can drive the water stop 300 to fit with the inner wall of the culvert 200; multiple second support seats 3 are movably arranged on the bracket 1 along the pressing direction, and multiple second support seats 3 are arranged at intervals along the circumference of the bracket 1, and the pressure plate 100 can be detachably installed on several second support seats 3, driving the second support seat 3 to move, the second support seat 3 can drive the corresponding pressure plate 100 to contact with the water stop 300 and push the corresponding pressure plate 100 to press the water stop 300 against the inner wall of the culvert 200. Among them, the pressing direction is the thickness direction of the water stop 300, so that part of the first support seat 2 is moved along the vertical direction ( Figure 2 The first support seat 2 moves along the horizontal direction ( Figure 2 The second supporting seats 3 move in the same direction as the first supporting seats 2, and some of the first supporting seats 2 move obliquely. The directions in which the second supporting seats 3 move are the same as those of the first supporting seats 2, which will not be described in detail here.

[0057] The underwater working platform for the waterstop 300 provided in the present embodiment, before entering the water, first lays the waterstop 300 on multiple first supporting seats 2, and installs multiple pressure plates 100 on multiple second supporting seats 3, so that the waterstop 300 is already in an unfolded state before entering the water, and there is no need for divers to unfold the waterstop 300 underwater, which reduces the difficulty of underwater installation of the waterstop 300 and improves the efficiency of underwater installation of the waterstop 300; moreover, the first supporting seat 2 and the second supporting seat 3 can also limit the movement of the waterstop 300 and the pressure plate 100 during the process of the bracket 1 entering the water, ensuring the smooth underwater installation of the waterstop 300. After the bracket 1 is installed in the culvert 201, multiple first supporting seats 2 are moved, and the multiple first supporting seats 2 drive the waterstop 300 to move, so that the waterstop 300 can be in contact with the inner wall of the culvert 200 along the circumference of the culvert 200; then, multiple second supporting seats 3 are moved, and the second supporting seats 3 can drive the pressure plate 100 installed thereon to move, so that the waterstop 300 is pressed against the inner wall of the culvert 200 along the circumference of the culvert 200; in the process of the pressure plate 100 gradually pressing the waterstop 300 and connecting the pressure plate 100 and the culvert 200, the divers no longer need to lift the pressure plate 100, and can easily pass the bolts through the pressure plate 100 and accurately align them with the reserved holes of the culvert 200, which reduces the workload of the divers in underwater operations, reduces the difficulty of underwater installation of the waterstop 300, significantly improves the efficiency of underwater installation of the waterstop 300, and ensures the safety of the divers' underwater operations. In the process of moving the first supporting seat 2 and the second supporting seat 3, the bracket 1 can provide multiple fulcrums for the diver's operation, so that the diver can perform long-term operations underwater, further reducing the difficulty of underwater operations.

[0058] In this embodiment, refer to Figure 1 and Figure 4 The support 1 includes a plurality of plane frames 11 and a plurality of connecting beams 12. The plurality of plane frames 11 extend along the direction of the box culvert 200 ( Figure 4 The Y direction in the middle) is arranged at intervals, and any two adjacent plane frames 11 are separated by multiple vertical directions ( Figure 4 The support 1 is connected by connecting beams 12 arranged at intervals (in the Z direction) to form a support 1 with a structure in the form of a space frame structure. The space frame structure has greater rigidity and better stability, so that the support 1 can withstand a greater load, ensuring the stability of the support 1 during underwater operation.

[0059] Specifically, see Figure 1 and Figure 4 The plane frame 11 includes a plurality of columns 111, and the plurality of columns 111 are arranged along the width direction of the box culvert 200 ( Figure 4Any two adjacent columns 111 are connected by a plurality of beams 112 which are arranged at intervals along the vertical direction.

[0060] For example, the support 1 is made of steel, which has high rigidity and is not easily deformed. It can withstand external forces such as water pressure and water flow impact, thus ensuring the stability and safety of the support 1 during underwater operation. Figure 1 and Figure 4 The cross-sectional shape of the box culvert 200 is rectangular, and the cross-sectional shape of the bracket 1 is also rectangular, so that the waterstop 300 can be more conveniently moved to fit the inner wall of the box culvert 200, and it also helps to ensure the accuracy of the installation position of the waterstop 300 in the box culvert 200; and the cross-sectional size of the bracket 1 is smaller than the size of the culvert 201, so that the bracket 1 can smoothly enter the culvert 201.

[0061] Optionally, see Figure 3 and Figure 5 The first supporting seat 2 includes a plurality of first supporting plates 21 and a plurality of first supporting rods 22. The plurality of first supporting plates 21 correspond to the plurality of first supporting rods 22 one by one. The first supporting plates 21 can be used to support the water stop belt 300. One end of the first supporting rod 22 is detachably connected to the corresponding first supporting plate 21, and the other end is passed through the bracket 1 along the pressing direction and is threadedly connected to the bracket 1. Figure 3 and Figure 6 The second supporting seat 3 includes a plurality of second supporting plates 31 and a plurality of second supporting rods 32, and the plurality of second supporting plates 31 correspond to the plurality of second supporting rods 32 one by one. The second supporting plates 31 can be detachably connected to the corresponding pressing plate 100, and one end of the second supporting rod 32 is detachably connected to the corresponding second supporting plate 31, and the other end is passed through the bracket 1 along the clamping direction and is threadedly connected to the bracket 1. The first supporting rod 22 is detachably connected to the corresponding first supporting plate 21, so that when installing waterstops 300 with different cross-sectional shapes, such as Ω waterstops 300 and flat waterstops 300, the first supporting plate 21 can be removed from the first supporting rod 22, and the first supporting plate 21 adapted to the shape of the waterstop 300 to be installed can be replaced, so that the first supporting plate 21 can support the waterstop 300 more stably. The first supporting rod 22 is threadedly connected to the bracket 1. By screwing the first supporting rod 22, the first supporting rod 22 can move along its extension direction and drive the first supporting plate 21 to move, so that the water stop 300 can gradually move to fit with the inner wall of the box culvert 200. The function of the second supporting plate 31 is the same as that of the first supporting plate 21, and the function of the second supporting rod 32 is the same as that of the first supporting rod 22, which will not be repeated here.

[0062] Specifically, a slot is provided on one side of the first supporting plate 21 facing the first supporting rod 22, and an insert plate is provided at the end of the first supporting rod 22, and the insert plate can be inserted into or disengaged from the slot through the side notch of the slot to achieve the connection or separation of the first supporting plate 21 and the first supporting rod 22. The connection method of the second supporting plate 31 and the second supporting rod 32 is the same as the connection method of the first supporting plate 21 and the first supporting rod 22, which will not be repeated here.

[0063] For example, see Figure 3 , Figure 5 and Figure 6 The water stop 300 adopts an Ω water stop 300, which includes a curved portion and two planar portions, and the two planar portions are arranged on both sides of the curved portion. The cross-sectional shape of the first supporting plate 21 is semicircular, and is used to support the curved portion of the Ω water stop 300. Two second supporting plates 31 are arranged on the second supporting seat 3, and the two second supporting plates 31 respectively support the two planar portions. The bracket 1 is provided with multiple first brackets 13 and multiple second brackets 14, each first supporting seat 2 is only provided with one first supporting rod 22, multiple first brackets 13 correspond one-to-one with the first supporting rods 22 of multiple first supporting seats 2, the cross-sectional shape of the first bracket 13 is L-shaped, and the first supporting rod 22 is threadedly connected with the short side of the corresponding L-shaped first bracket 13; each second supporting seat 3 is provided with two second supporting rods 32, multiple second brackets 14 correspond one-to-one with the multiple second supporting seats 3, the cross-sectional shape of the second bracket 14 is T-shaped, and the two second supporting rods 32 of each second supporting seat 3 are threadedly connected with the head of the corresponding T-shaped second bracket 14, and are symmetrically arranged on the corresponding T-shaped second bracket 14.

[0064] Further, see Figure 5 and Figure 6 The end of the first supporting rod 22 away from the first supporting plate 21 and the end of the second supporting rod 32 away from the second supporting plate 31 are both provided with an operating disk 23, and the first supporting rod 22 or the second supporting rod 32 can be driven to rotate by rotating the operating disk 23. The provision of the operating disk 23 increases the convenience for the diver to screw the first supporting rod 22 and the second supporting rod 32 underwater, and is more convenient for the diver to use underwater.

[0065] In this embodiment, the underwater working platform for the waterstop 300 also includes multiple binding parts, and the multiple binding parts correspond one by one to the multiple first supporting seats 2. The binding parts are used to bind the waterstop 300 to the corresponding first supporting seats 2 to avoid the waterstop 300 from being separated from the first supporting seats 2 during the underwater working platform entering the water, thereby reducing the difficulty of underwater operations and facilitating the smooth installation of the subsequent waterstop 300 on the culvert 200.

[0066] Exemplarily, the binding member is a binding rope.

[0067] In other embodiments, see Figure 1 , Figure 3 and Figure 6 An adsorption member 33 is provided on the second supporting plate 31, and the pressure plate 100 can be adsorbed on the corresponding second supporting plate 31 by the adsorption member 33 to avoid the separation of the pressure plate 100 and the second supporting seat 3 during the entry of the underwater working platform into the water, thereby reducing the difficulty of underwater operations and ensuring the smooth installation of the subsequent water stop belt 300 on the culvert 200.

[0068] Exemplarily, the pressing plate 100 is made of metal, and the adsorbing member 33 is a magnet.

[0069] In other embodiments, the underwater working platform for the waterstop 300 includes both a binding part and an adsorption part 33, so that the waterstop 300 will not be separated from the first supporting seat 2 and the pressure plate 100 will not be separated from the corresponding second supporting seat 3 during the underwater working platform entering the water.

[0070] Optionally, see Figure 1 , Figure 7 and Figure 8 The bracket 1 is provided with a plurality of support members 4 arranged at intervals along the circumference thereof. The extension length of the support members 4 is adjustable and can abut against or separate from the inner wall of the culvert 200. The support members 4 can abut against or separate from the inner wall of the culvert 200 by adjusting the length of the support members 4. When the support members 4 abut against the inner wall of the culvert 200, the plurality of support members 4 can provide support for the bracket 1 in different directions, thereby preventing the bracket 1 from moving or tipping over during the installation of the water stop 300, ensuring the stability of the bracket 1 installed in the culvert 201, and ensuring the safety of the diver's underwater operation.

[0071] Further, see Figure 1 and Figure 2 , the bracket 1 extends along the direction of the box culvert 200 ( Figure 2 A plurality of support members 4 are provided on both sides of the culvert 200 in the Y direction, and the plurality of support members 4 are provided in the width direction ( Figure 2 The brackets 1 are symmetrically arranged in the X direction (in the X direction) so that the bracket 1 can be subjected to symmetrical supporting forces, further ensuring the stability of the bracket 1 when installed in the culvert 201.

[0072] Specifically, see Figure 1 , Figure 7 and Figure 8 The bracket 1 is provided with connecting plates 15 corresponding to the plurality of supporting members 4 one by one, and the supporting members 4 are fixedly connected to the corresponding connecting plates 15. The cross-sectional shape of the connecting plates 15 is preferably a bull leg shape, so that the supporting force can be transmitted to the bracket 1 along the axial direction of the supporting member 4, thereby ensuring the stability of the connection between the connecting plates 15 and the supporting member 4. Figure 1 , Figure 7 and Figure 8The support member 4 is arranged at an angle to the plane where the bracket 1 is located, so that when the support member 4 abuts against the inner wall of the box culvert 200, the support member 4, the bracket 1 and the inner wall of the box culvert 200 are arranged in a triangle to ensure the firmness of the support of the support member 4.

[0073] Further, see Figure 1 and Figure 8 An abutment portion 41 is provided at one end of the support member 4 away from the bracket 1, and an abutment slope 411 is provided on the abutment portion 41, which is arranged at an angle to the axial direction of the support member 4, so that when the support member 4 abuts against the inner wall of the box culvert 200, the abutment slope 411 can fit with the inner wall of the box culvert 200, thereby ensuring the stability of the support member 4 when contacting the inner wall of the box culvert 200, and effectively limiting the displacement of the support member 4 on the inner wall of the box culvert 200.

[0074] Exemplarily, twelve support members 4 are provided, six support members 4 are provided on each side along the extension direction of the box culvert 200 , and the six support members 4 are respectively located at the upper part, the middle part and the lower part of the bracket 1 .

[0075] In an alternative embodiment, see Figure 8 The support member 4 includes a first connecting rod 42, a second connecting rod 43 and a connecting pipe 44. One end of the first connecting rod 42 is connected to the bracket 1, and the other end extends into the first end of the connecting pipe 44. One end of the second connecting rod 43 extends into the second end of the connecting pipe 44, and the other end can abut against the inner wall of the culvert 200. The first connecting rod 42 and the first end of the connecting pipe 44, and the second connecting rod 43 and the second end of the connecting pipe 44 are both threadedly connected, and the threading directions of the first connecting rod 42 and the second connecting rod 43 are opposite. By screwing the connecting pipe 44, the length of the first connecting rod 42 and the second connecting rod 43 extending into the connecting pipe 44 changes, that is, the extension length of the support member 4 changes, so as to achieve the abutment or separation of the support member 4 and the inner wall of the culvert 200. Moreover, the threaded connection operation is simple, and the first connecting rod 42 and the second connecting rod 43 can move stably in the connecting pipe 44. The threads of the first connecting rod 42 and the second connecting rod 43 are rotated in opposite directions, so that when the first connecting rod 42 and the connecting tube 44 are tightened, the second connecting rod 43 and the connecting tube 44 that have been tightened will not be loosened, or when the second connecting rod 43 and the connecting tube 44 are tightened, the first connecting rod 42 and the connecting tube 44 that have been tightened will not be loosened. The length of the first connecting rod 42 extending into the connecting tube 44 and the length of the second connecting rod 43 extending into the connecting tube 44 can be adjusted separately, making the adjustment range of the length of the support member 4 more flexible and convenient.

[0076] In this embodiment, refer to Figure 8A first nut 441 is provided at the first end of the connecting tube 44, and a second nut 442 is provided at the second end of the connecting tube 44. The first connecting rod 42 and the second connecting rod 43 are both screw rods. The first connecting rod 42 is threadedly connected to the first nut 441, and the second connecting rod 43 is threadedly connected to the second nut 442.

[0077] Exemplarily, the connecting pipe 44 is a hollow round steel pipe, and the connecting pipe 44 is welded to the first nut 441 and the second nut 442 to limit the displacement of the first nut 441 and the second nut 442 on the connecting pipe 44 .

[0078] In other embodiments, an internal thread is provided on the inner hole wall of the connecting tube 44, and the internal thread is provided along the extension direction of the connecting tube 44, and the internal thread is preferably provided along the entire length of the connecting tube 44 to increase the movable length of the first connecting rod 42 and the second connecting rod 43, and expand the adjustment range of the length of the support member 4.

[0079] Furthermore, a driving hole is provided on the connecting tube 44, and the driving hole is configured to be inserted with a driving rod, and the connecting tube 44 can be driven to rotate by applying force of the driving rod, so as to facilitate the adjustment of the length of the supporting member 4. The driving rod is preferably an Allen wrench or a steel bar. When adjusting the length of the supporting member 4, one end of the Allen wrench or the steel bar is inserted into the driving hole, and the Allen wrench or the steel bar is driven to rotate around the center line of the supporting member 4 to adjust the distance between the first connecting rod 42 and the second connecting rod 43, thereby achieving the adjustment of the length of the supporting member 4.

[0080] In another optional embodiment, the first connecting rod 42 and the first end of the connecting tube 44 , and the second connecting rod 43 and the second end of the connecting tube 44 are slidably connected to achieve adjustment of the extension length of the support member 4 .

[0081] Specifically, the support member 4 also includes a bolt and a third nut, a first connecting hole is provided at one end of the first connecting rod 42 located in the connecting tube 44, a second connecting hole is provided at one end of the second connecting rod 43 located in the connecting tube 44, and a plurality of first fixing holes and a plurality of second fixing holes are arranged at intervals on the connecting tube 44 along its extension direction, and the first fixing holes and the second fixing holes are symmetrically arranged along the axis of the extension direction of the connecting tube 44. When the first connecting rod 42 slides to the designated position in the connecting tube 44, the screw of the bolt passes through the first fixing hole, the first connecting hole and the second fixing hole in sequence, the head of the bolt abuts against the outer wall of the connecting tube 44 around the first fixing hole, the third nut abuts against the outer wall of the connecting tube 44 around the second fixing hole and is tightened with the bolt to fix the sliding position of the first connecting rod 42 in the connecting tube 44; when the second connecting rod 43 slides to the designated position in the connecting tube 44, the screw of the bolt passes through the first fixing hole, the second connecting hole and the second fixing hole in sequence, the head of the bolt abuts against the outer wall of the connecting tube 44 around the first fixing hole, the third nut abuts against the outer wall of the connecting tube 44 around the second fixing hole and is tightened with the bolt to fix the sliding position of the second connecting rod 43 in the connecting tube 44, thereby completing the adjustment of the length of the support member 4. The designated position where the first connecting rod 42 and the second connecting rod 43 slide in the connecting tube 44 refers to the position where the second connecting rod 43 can abut or separate from the inner wall of the box culvert 200. Such arrangement allows the lengths of the first connecting rod 42 and the second connecting rod 43 extending into the connecting tube 44 to be adjusted simultaneously, and the lengths of the first connecting rod 42 and the second connecting rod 43 extending into the connecting tube 44 to be adjusted individually, making the adjustment range of the length of the support member 4 more flexible and convenient.

[0082] In an alternative embodiment, see Figure 3 The underwater working platform for the water stop 300 also includes a plurality of first working platforms 51, which are fixedly arranged on the bracket 1.

[0085] In this embodiment, refer to Figure 3 and Fig. 9 The underwater working platform for the waterstop 300 also includes a connecting rope 521, one end of the connecting rope 521 is connected to the second working platform 52, and the other end is connected to the bracket 1. When in the construction state, the connecting rope 521 is tightened to limit the second working platform 52 to the construction state, thereby ensuring the safety of divers when working on the second working platform 52.

[0086] Exemplarily, the connecting rope 521 is made of a steel chain, and the second working platform 52 is made of a steel plate.

[0087] Furthermore, a rotatable limit member is provided on the bracket 1. When in the recovery state, the limit member rotates to the side of the second working platform 52 away from the bracket 1 and contacts the second working platform 52. At this time, the second working platform 52 is clamped between the limit member and the bracket 1, that is, it is limited to the recovery state; rotate the limit member, and when the limit member is rotated to separate from the second working platform 52, the second working platform 52 can rotate.

[0088] In this embodiment, refer to Fig. 9 A rotating shaft 522 is provided on the second working platform 52, and a connecting ear plate 16 is provided on the bracket 1. The rotating shaft 522 passes through the connecting ear plate 16 and rotatably cooperates with the connecting ear plate 16 to realize the rotational connection between the second working platform 52 and the bracket 1.

[0089] In another alternative embodiment, see Figure 4 Both a first working platform 51 and a second working platform 52 are provided to provide multiple fulcrums for divers to work, thereby improving the convenience of divers working underwater.

[0090] In this embodiment, refer to Figure 1 and Figure 4 There are two first working platforms 51, and the two first working platforms 51 are arranged along the extension direction of the box culvert 200 ( Figure 4The two first working platforms 51 are symmetrically arranged along the Y direction of the culvert 200, and the two first working platforms 51 are both arranged on the upper part of the bracket 1. The diver can sit on the first working platform 51 to adjust the multiple first supporting seats 2 and the multiple second supporting seats 3 located on the top of the bracket 1; the second working platforms 52 are provided with eight, and the eight second working platforms 52 are arranged along the extension direction of the box culvert 200 ( Figure 4 The support 1 and the support 1 are symmetrically arranged in the Y direction, wherein the upper part of the support 1 and the lower part of the support 1 are each provided with four second working platforms 52, and the diver can stand and adjust the multiple first supporting seats 2 and the multiple second supporting seats 3 located in the upper part of the support 1 on the four second working platforms 52 located in the upper part of the support 1, and the diver can stand and adjust the multiple first supporting seats 2 and the multiple second supporting seats 3 located in the lower part of the support 1 on the four second working platforms 52 located in the lower part of the support 1.

[0091] Optionally, see Figure 2 and Figure 3 The underwater working platform for the water stop 300 also includes a plurality of suspension members 6, which are detachably arranged on the bracket 1 and are used to adjust the buoyancy value of the bracket 1. The buoyancy value of the bracket 1 is related to the volume of water displaced by the bracket 1. The arrangement of the suspension members 6 can increase the volume of water displaced by the bracket 1, thereby increasing the buoyancy value of the bracket 1; when the buoyancy value of the bracket 1 needs to be reduced under other working conditions, the suspension members 6 can be removed from the bracket 1, which is convenient and quick to operate.

[0092] Exemplarily, the suspension member 6 is a steel buoyancy box, and is detachably connected to the bracket 1 by bolts. Compared with the hollow structure, the volume of water that can be displaced by the box is larger, and it is more convenient to adjust the buoyancy value of the bracket 1.

[0093] Furthermore, the buoyancy value of the bracket 1 can be adjusted by using suspension members 6 of different volumes, thereby increasing the adjustable range of the buoyancy value of the bracket 1 .

[0094] Optionally, see Figure 4 and Figure 7 The underwater working platform for the water stop 300 also includes a walking assembly 7, which is arranged at the bottom of the bracket 1 and is configured to drive the bracket 1 to move so that divers can move the underwater working platform underwater.

[0095] In this embodiment, the walking assembly 7 includes a plurality of universal wheels, which are arranged at the bottom of the columns 111 located at the four corners of the bracket 1, so as to facilitate the movement of the bracket 1 in any direction.

[0096] Furthermore, the walking assembly 7 also includes a brake component. When the bracket 1 is moved to a suitable position, the universal wheel can be braked by the brake component, so that the bracket 1 remains stationary at the current position; when the bracket 1 needs to be moved, it is only necessary to release the brake component to restore the universal wheel to a rotatable state.

[0097] Optionally, the underwater operation platform for the water stop 300 further includes a lighting component, which is disposed on the bracket 1 and is configured to provide a light source. The lighting component can provide light for the underwater operation of the workers, improve the visibility of the underwater operation, and improve the convenience of the underwater operation of the workers.

[0098] Exemplarily, the lighting element is a waterproof lamp.
