Description

Technical Field

[0001] The present invention relates to the field of bridge construction, and particularly relates to a device for preparing a bridge pile foundation well enclosure and isolation. Background Art

[0002] The bridge foundation is the lowest part of the bridge structure that directly contacts the foundation, and is an important part of the bridge substructure. The part of the stratum that bears the load transmitted from the foundation is called the foundation soil. According to different structures and construction methods, the types of bridge foundations can be divided into: open excavation foundation, pile foundation, caisson foundation, caisson foundation and pipe column foundation.

[0003] Most bridge foundations are placed in water. In the prior art, usually the steel casing is first driven into the water. In this process, the steel casing needs to pass through the sediment covering layer at the bottom of the water, and the steel casing is driven into the geological rock layer at the bottom. At this time, there is mud in the steel casing. Therefore, it is necessary to carry out drilling construction by a rotary drilling rig. After that, the muddy water in the steel casing needs to be pumped out, then a steel bar framework is placed into the steel casing, and finally cement is poured into the steel casing. When the cement and the steel bar framework in the steel casing solidify together, the steel casing is removed to complete the construction of the bridge pile foundation.

[0004] However, there are still some problems in the actual construction process of this method. Therefore, technicians in related fields have also carried out a lot of optimizations. For more accurate comparison, for example, Chinese Patent No. CN110644483B discloses a bridge underwater pile foundation construction device. When in use, when rotary drilling and the drill bit is lifted to remove slag, since the transfer mud tank continuously supplies mud to the steel casing, the hole wall is sealed, and the mud liquid level will not fluctuate greatly. In addition, the drilling mechanism adopts an impact reverse circulation drilling device. The setting of the drilling mechanism can discharge the drilled slag while drilling, effectively avoiding the problem of difficult demoulding.

[0005] Furthermore, when it is necessary to build a bridge pile foundation on some small rivers, due to the fact that the above construction process requires the use of large-scale construction machinery, considering the construction cost, the above construction method is difficult to apply. And when large-scale construction machinery is difficult to enter the construction site, the above construction method is also difficult to apply. In the case of needing to reduce the construction cost and facilitate the transportation of construction materials, it is particularly important to isolate an area in the water for artificial construction of the bridge pile foundation. Therefore, under the above-mentioned viewpoints, the bridge pile foundation enclosure and isolation technology of the prior art still has room for improvement. Summary of the Invention

Detailed implementation manners

[0035] The following will Figures 1 to 10 describe the embodiments of the present invention in detail. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0036] The embodiments of the present application disclose a preparation device for isolating and enclosing a bridge pile foundation well. It should be noted that this preparation device for isolating and enclosing a bridge pile foundation well is mainly applied in the process of building a bridge pile foundation. In terms of technical effects, it can isolate water in different areas for the base well enclosure for building the bridge pile foundation in water, and then drain the water in the base well enclosure to facilitate the construction of the bridge pile foundation in the base well enclosure; further, this preparation device for isolating and enclosing a bridge pile foundation well is also convenient for disassembly and transportation, so as to be applicable to small rivers with low construction costs and environments where large mechanical equipment is difficult to enter.

[0037] Example 1:

[0038] Referring to Figure 1 and Figure 2 As shown, a preparation device for surrounding and isolating a bridge pile foundation well includes a surrounding plate 10, a plugging rod 11, a well surrounding 1 for the bridge pile foundation, a parallel connecting member 12, a vertical connecting plate 100, a vertical connecting member 13, a support mechanism 2 and a drainage mechanism 3. Both ends of the surrounding plate 10 are hook-shaped structures, and the hook-shaped structures on both sides face in opposite directions. The hook-shaped structures facilitate the connection of the surrounding plates 10 to each other. A plugging rod 11 is provided in the middle of the lower end of the surrounding plate 10. The plugging rod 11 is used to insert the surrounding plate 10 into the bottom of the river channel, thereby improving the stability of the installation of the surrounding plate 10.

[0039] A plurality of surrounding plates 10 are assembled into a well surrounding 1 with a rectangular frame structure. The well surrounding 1 for the bridge pile foundation is used to separate an area in the river channel, so as to facilitate the construction of the bridge pile foundation inside the well surrounding 1 from which the river water has been drained. In order to improve the connection stability and sealing performance between the surrounding plates 10, a parallel connecting member 12 is provided between the parallel and adjacent surrounding plates 10. The mutually perpendicular and adjacent surrounding plates 10 are called vertical connecting plates 100 to facilitate the subsequent description of the surrounding plates 10 in special positions. Corresponding vertical connecting members 13 and support mechanisms 2 are provided between the vertical connecting plates 100. The vertical connecting members 13 can also improve the connection stability and sealing performance between the vertical connecting plates 100.

[0040] Moreover, the surrounding plate 10, the parallel connecting member 12 and the vertical connecting member 13 are easy to disassemble, assemble and transport. By using the surrounding plate 10, the parallel connecting member 12 and the vertical connecting member 13 to surround the well surrounding 1 in the river channel, it is possible to isolate the river water during the construction of the bridge pile foundation of a small river when large construction machinery is difficult to enter. Further, the surrounding plate 10 can also isolate different areas in the river channel according to the construction requirements, thereby improving the applicability of the present invention. A drainage mechanism 3 is provided on the support mechanism 2. The drainage mechanism 3 is used to continuously drain the water inside the well surrounding 1 for the bridge pile foundation to the outside, thereby avoiding the problem that the construction of the bridge pile foundation is affected by excessive seepage of river water from the bottom of the well surrounding 1 upwards.

[0041] Referring to Figure 3 As shown, which is the parallel connecting member 12 in the present application. Specifically, the parallel connecting member 12 includes a first sealing connecting strip 120, a limiting arc strip 121 and a connecting sleeve 122. The first sealing connecting strip 120 for sealing and waterproofing is arranged between the ends of the surrounding plate 10, so as to prevent the water outside the well surrounding 1 from entering the well surrounding 1 through the connection part of the surrounding plate 10. The first sealing connecting strip 120 is an S-shaped structure, so as to better adapt to the end shape between the parallel-connected surrounding plates 10.

[0042] At both ends of the first sealing connecting strip 120, there are provided limiting arc strips 121 that fit with the hook parts of the surrounding plates 10. The limiting arc strips 121 are made of a non-deformable material, enabling the limiting arc strips 121 to limit the ends of the surrounding plates 10 on both sides of them, thereby improving the stability of the parallel connection of the surrounding plates 10; a connecting sleeve 122 integrally formed with the corresponding first sealing connecting strip 120 is coated on the outer side of the limiting arc strip 121, and the connecting sleeve 122 can improve the connection stability between the limiting arc strip 121 and the first sealing connecting strip 120.

[0043] Continue to refer to Figure 4 As shown, that is, the vertical connecting member 13 in the present application; specifically, the vertical connecting member 13 includes a second sealing connecting strip 130, a limiting inner strip 131, and a limiting hook strip 132. The C-shaped second sealing connecting strip 130 is arranged between the end of one vertical connecting plate 100 and the inner side of the hook part of another vertical connecting plate 100. The shape of the second sealing connecting strip 130 can fit well with the connection part of the vertical connecting plates 100, and the second sealing connecting strip 130 can prevent the water outside the basic well enclosure 1 from entering the basic well enclosure 1 through the connection part of the vertical connecting plates 100.

[0044] Both the second sealing connecting strip 130 and the first sealing connecting strip 120 are made of elastic rubber material. When the water inside the basic well enclosure 1 is discharged outward, the water pressure outside the basic well enclosure 1 will squeeze the surrounding plates 10. At this time, the materials of the second sealing connecting strip 130 and the first sealing connecting strip 120 can further improve the sealing effect of the first sealing connecting strip 120 and the second sealing connecting strip 130; an approximately triangular-structured limiting inner strip 131 is arranged at one end of the second sealing connecting strip 130 located inside the basic well enclosure 1.

[0045] The limiting inner strip 131 is made of a non-deformable material, so the limiting inner strip 131 can limit the inside of the vertical connecting plates 100; at one end of the second sealing chain located outside the basic well enclosure 1, there is provided a limiting hook strip 132 for limiting the connection part of the vertical connecting plates 100 and having a hook-shaped structure. The outer sides of the limiting hook strip 132 and the limiting inner strip 131 are also coated with a connecting sleeve 122 integrally formed with the corresponding second sealing connecting strip 130 to improve the connection stability between the limiting hook strip 132 and the limiting inner strip 131 and the corresponding second sealing connecting strip 130.

[0046] The lower ends of the limiting arc strip 121, the limiting inner strip 131 and the limiting hook strip 132 are also provided with insertion rods 11, and the lower ends of the insertion rods 11 are of a conical structure. The conical structure facilitates the insertion of the insertion rods 11 into the bottom of the river channel, and the insertion rods 11 can improve the stability of the limiting arc strip 121, the limiting inner strip 131 and the limiting hook strip 132 in the river channel. Further, the insertion rods 11 are detachably connected to the limiting arc strip 121, the limiting inner strip 131, the limiting hook strip 132 and the surrounding plate 10. When the present invention is not needed, the insertion rods 11 can be removed, so as to facilitate the transportation and storage of the limiting arc strip 121, the limiting inner strip 131, the limiting hook strip 132 and the surrounding plate 10 after the insertion rods 11 are removed.

[0047] Embodiment 2:

[0048] Referring to Figure 5 As shown in the figure, on the basis of Embodiment 1, in order to improve the stability of the well base enclosure 1, a support mechanism 2 for reinforcement is further provided between the vertical connecting plates 100. Specifically, the support mechanism 2 includes mounting blocks 20, pin shafts 21, support plates 22, connecting insertion rods 23, connecting plates 24 and support connecting plates 25. Multiple groups of mounting blocks 20 are uniformly arranged on the vertical connecting plates 100 and located inside the well base enclosure 1. One group of mounting blocks 20 consists of two arranged vertically. A pin shaft 21 is arranged between the vertically corresponding mounting blocks 20, and a support plate 22 is rotatably arranged between the pin shafts 21. The opposite sides of the horizontally adjacent support plates 22 are in concave-convex fit. Connecting the concave-convex fit parts of the horizontally adjacent support plates 22 can improve the stability of the vertical connecting plates 100 when installed.

[0049] Therefore, insertion through grooves are opened at the concave-convex fit parts of the support plates 22, and connecting insertion rods 23 are inserted into the insertion through grooves in a detachable manner. A connecting plate 24 is arranged between one ends of the vertically corresponding connecting insertion rods 23. The connecting plate 24 facilitates the insertion of the vertically corresponding connecting insertion rods 23 into the corresponding connecting through grooves, thereby improving the efficiency of fixing the horizontally adjacent support plates 22.

[0050] A support connecting plate 25 with a U-shaped structure is slidably arranged outside the connecting plate 24. The support connecting plate 25 and the connecting plate 24 are connected to the drainage mechanism 3. Insertion grooves corresponding to the connecting insertion rods 23 are opened on the support connecting plate 25, and one ends of the connecting insertion rods 23 close to the support connecting plate 25 are all located in the corresponding insertion grooves, so as to support and fix one ends of the connecting insertion rods 23 far from the connecting plate 24, thereby further improving the stability degree of the connecting insertion rods 23 in fixing the support plates 22.

[0051] When it is necessary to remove the support mechanism 2, slide the support connecting plate 25 to the side away from the corresponding connecting plate 24 to disengage it from the connecting insertion rod 23, and then drive the connecting insertion rod 23 to disengage from the insertion through slot through the connecting plate 24. Then, the support plate 22 can be rotated and folded towards the side of the corresponding vertical connecting plate 100, and the folded support plate 22 is convenient for subsequent transportation and storage of the vertical connecting plate 100.

[0052] Referring to Figure 6 As shown, it can be seen from the above-disclosed technical solution that although the support connecting plate 25 can be installed outside the connecting plate 24, the connecting plate 24 and the support connecting plate 25 cannot be fixed. Therefore, the support connecting plate 25 is still likely to fall off from the connecting plate 24 and the connecting insertion rod 23. Thus, in order to improve the connection stability between the connecting plate 24 and the support connecting plate 25, a connecting unit 26 for fixing the connecting plate 24 and the support connecting plate 25 is provided; specifically, the connecting unit 26 includes an extension plate 260, an installation groove 261, a pin shaft connecting rod 262, a locking plate 263, and a magnetic block 264.

[0053] The H-shaped extension plate 260 is arranged at the upper and lower ends of the connecting plate 24 and inside the support connecting plate 25. Installation grooves 261 corresponding to the concave portions on the extension plate 260 are symmetrically formed on the opposite sides of the horizontal folded edges on the upper and lower sides of the support connecting plate 25. A pin shaft connecting rod 262 is arranged in the installation groove 261, and a locking plate 263 for limiting the extension plate 260 is rotatably arranged on the outer side surface of the pin shaft connecting rod 262; the locking plate 263 is made of a metal material that can be magnetically adsorbed, and the lower end of the upper locking plate 263 will rotate to the concave portion on the extension plate 260 under the action of gravity, so as to fix the upper extension plate 260.

[0054] A magnetic block 264 for magnetically adsorbing the lower locking plate 263 is arranged at the upper end of the lower extension plate 260, and the lower locking plate 263 will rotate to the concave portion on the lower extension plate 260 under the magnetic force of the magnetic block, so as to fix the lower extension plate 260, thereby playing a role in fixing the connecting plate 24 and the support connecting plate 25; when it is necessary to remove the support connecting plate 25 and the connecting plate 24, rotate the lock to disengage it from the corresponding extension plate 260, so that the support connecting plate 25 and the connecting plate 24 are no longer locked, and then the connecting plate 24 and the support connecting plate 25 can be removed.

[0055] Embodiment 3:

[0056] Referring to Figure 7As shown, on the basis of the second embodiment, in order to avoid a large impact force on the well base enclosure 1 caused by the water flow in the river channel, a buffer structure 4 for reducing the water flow impact can also be provided on one side of the well base enclosure 1; specifically, the buffer structure 4 is an L-shaped structure formed by an enclosure plate 10, parallel connectors 12, vertical connectors 13, insertion rods 11, and a support mechanism 2. When it is necessary to reduce the impact force of the water flow on the well base enclosure 1, the buffer structure 4 is inserted into the river channel through the insertion rods 11, and the buffer structure 4 is located on the water inlet side of the well base enclosure 1. It is also necessary to make the opening of the buffer structure 4 abut against the well base enclosure 1. At this time, the well base enclosure 1 can provide some supporting force for the buffer structure 4, thereby preventing the buffer structure 4 from being washed down by the water flow, and the buffer structure 4 can reduce the impact force of the water flow on the well base enclosure 1, thereby improving the stability of the installation of the well base enclosure 1.

[0057] Embodiment Four:

[0058] Referring to Figure 8 and Figure 9 As shown, on the basis of the third embodiment, since water continuously seeps upward from the bottom inside the well base enclosure 1, in order to avoid affecting the construction of the bridge pile foundation due to too much water seepage inside the well base enclosure 1, it is necessary to continuously drain the water inside the well base enclosure 1, and the drainage process cannot affect the construction of the bridge pile foundation. Therefore, a drainage mechanism 3 for drainage is provided on the support mechanism 2; specifically, the drainage mechanism 3 includes a mounting frame 30, a driving roller 31, a driving motor 32, a belt pulley 33, a transmission belt 34, and a drainage unit 35.

[0059] The mounting frames 30 are symmetrically arranged at both ends of the horizontal folded edge of the support connecting plate 25. A driving roller 31 is rotatably arranged between two mounting frames 30 at the same height and corresponding to each other. One end of the driving roller 31 passes through the corresponding mounting frame 30 and is provided with a driving motor 32. The driving motor 32 is fixed to the corresponding mounting frame 30 through a motor base. A belt pulley 33 is arranged on the outer side surface of the driving roller 31. A transmission belt 34 is arranged between the upper and lower corresponding belt pulleys 33. A drainage unit 35 is arranged on the outer side of the transmission belt 34; the driving motor 32 can drive the belt pulley 33 and the transmission belt 34 to rotate through the driving roller 31, and the transmission belt 34 can drive the drainage unit 35 to perform drainage operations.

[0060] Referring to Figure 8As shown, since the drive belt 34 will bear the pressure of water when driving the drainage unit 35 to perform drainage operations, in order to prevent the drive belt 34 from disengaging from the pulley 33 due to the pressure, and also to improve the stability of the operation of the drive belt 34, a limiting component 37 for limiting the drive belt 34 is provided; specifically, the limiting component 37 includes limiting side plates 370 and U-shaped side plates 371. The limiting side plates 370 are symmetrically arranged on both sides of the connecting plate 24, and U-shaped side plates 371 corresponding to the limiting side plates 370 are symmetrically arranged on the outer side of the supporting connecting plate 25; the cooperation of the U-shaped side plates 371 and the limiting side plates 370 can effectively limit the drive belt 34, thereby preventing the drive belt 34 from disengaging from the pulley 33 due to the pressure of water, and further improving the stability of the drive belt 34 during operation.

[0061] Referring to Figure 9 and Figure 10 As shown, that is, the drainage unit 35 driven by the drive belt 34 in this application for drainage; specifically, the drainage unit 35 includes a mounting rod 350, a connecting round block 351, a water scooping box 352, a reset spring 353, an L-shaped connecting plate 354, and a push box assembly 36. The mounting rods 350 are uniformly arranged on the outer side surface of the drive belt 34, and the margin of the drive belt 34 with respect to the pulley 33 is sufficient for the mounting rods 350 to pass through the pulley 33; a connecting round block 351 is rotatably arranged at one end of the mounting rod 350 away from the drive belt 34, and a water scooping box 352 for scooping water from the inside of the foundation well enclosure 1 is arranged at one end of the connecting round block 351 away from the mounting block 20.

[0062] The water scooping box 352 is a box-shaped structure with a hollow interior and an open end. The end of the water scooping box 352 opposite to the open end is the bottom of the box, and the connecting round blocks 351 are all located on the side close to the open end of the water scooping box 352, so that the open end of the water scooping box 352 on the side close to the corresponding vertical connecting piece 13 faces upward; a reset spring 353 for maintaining its balance is arranged on one side of the bottom of the box of the water scooping box 352. The end of the reset spring 353 away from the corresponding water scooping box 352 is provided with an L-shaped connecting plate 354. The vertical side of the L-shaped connecting plate 354 is fixed to the corresponding mounting rod 350, so that the bottom of the box of the water scooping box 352 can be limited by the reset spring 353 and the L-shaped connecting plate 354, thereby preventing the water scooping box 352 from rotating around the connecting round block 351, and further making the open end of the water scooping box 352 on the side away from the vertical connecting piece 13 face downward.

[0063] When the drive belt 34 drives the water scooping box 352 with the opening facing downward to move toward the side close to the water scooping box 352 with the opening facing upward, the water scooping box 352 can pick up water and sediment at the bottom of the river from the bottom of the drive belt 34. And then, with the opening facing upward, the water scooping box 352 will drive the water inside it to move upward; both the end of the water scooping box 352 far from the corresponding mounting block 20 and the bottom of the water scooping box 352 are arc-shaped structures. On the mounting frame 30 on the side of the upper end of the support connecting plate 25 far from the reset spring 353, there is a push box assembly 36 for overturning the water scooping box 352.

[0064] When the water scooping box 352 with water or sediment moves upward to the push box assembly 36, the push box assembly 36 will overturn the water scooping box 352, so that the water or sediment in the water scooping box 352 can be discharged along the push box assembly 36 to the outside of the well foundation enclosure 1, and then the function of discharging the water in the well foundation enclosure 1 to the outside can be realized; after the water and sediment in the water scooping box 352 are discharged outward, it will be reset under the pulling force of the reset spring 353, so that when the empty water scooping box 352 rotates with the drive belt 34 to the side far from the corresponding vertical connecting piece 13, it can keep the opening facing downward, so that the water scooping box 352 with the opening facing downward can take water again when it moves to the bottom of the drive belt 34, thus forming a cyclic continuous drainage.

[0065] Both the end of the water scooping box 352 far from the corresponding mounting block 20 and the bottom of the water scooping box 352 are arc-shaped structures. The arc-shaped structure at the end of the water scooping box 352 far from the corresponding mounting block 20 is convenient for the water scooping box 352 to pick up water from the bottom of the river, and the arc-shaped structure at the bottom of the water scooping box 352 can avoid interference between the water scooping box 352 and the vertical connecting plate 100 during rotation, thereby improving the use effect of the water scooping box 352.

[0066] Continue to refer to Figure 9 and Figure 10 shown, that is, the push box assembly 36 in the present application for overturning the water scooping box 352 with the opening facing upward and discharging the water and sediment inside it to the outside of the well foundation enclosure 1; specifically, the push box assembly 36 includes a limit stop rod 360, a drainage through groove 361, a drainage frame plate 362, a bolt 363, a reset compression spring rod 364 and an extension baffle 365. The limit stop rod 360 for blocking the water scooping box 352 with the opening facing upward is inserted into the mounting frame 30 on the side of the upper end of the support connecting plate 25 far from the reset spring 353 in a detachable manner. The limit stop rod 360 is located on the side close to the corresponding vertical connecting piece 13, and the limit stop rod 360 will not block the connecting round block 351; when the water scooping box 352 moves upward to the limit stop rod 360, it will tilt and rotate along the connecting round block 351 under the block of the limit stop rod 360, and at this time, the water and sediment in the water scooping box 352 can be discharged outward.

[0067] In order to guide the water discharged from the water ladling box 352 to the outside of the foundation well enclosure 1, a drainage through groove 361 is opened at the upper end of the vertical connecting plate 100 corresponding to the limit stop rod 360. A drainage frame plate 362 which is located below the limit stop rod 360 and has a U-shaped structure is inclinedly arranged in the drainage through groove 361. The drainage frame plate 362 is fixed to the corresponding vertical connecting plate 100 through bolts 363. A reset compression spring rod 364 is arranged in the middle of the upper end of the drainage frame plate 362, and the elasticity of the reset compression spring rod 364 is less than the pulling force of the reset tension spring 353. An extension baffle 365 for receiving water and sediment is arranged at the telescopic end of the reset compression spring rod 364 on the side close to the corresponding limit stop rod 360.

[0068] When the water ladling box 352 moves upward to the extension baffle 365, it will squeeze the extension baffle 365 towards one end close to the corresponding reset compression spring rod 364. At this time, since the elasticity of the reset compression spring rod 364 is less than the pulling force of the reset tension spring 353, the water ladling box 352 will not tilt. When the water ladling box 352 tilts under the action of the limit stop rod 360, the water ladling box 352 will not exert pressure on the extension baffle 365, and at this time, the extension baffle 365 will move towards the side close to the corresponding water ladling box 352 under the action of the reset compression spring rod 364, so that the water and sediment poured out from the water ladling box 352 can fall onto the upper end of the extension baffle 365. Then, the water and sediment will move from the upper end of the extension baffle 365 to the upper end of the corresponding drainage frame plate 362, so that the water and sediment can be discharged to the outside of the foundation well enclosure 1.

[0069] During this process, the vertical folding edge of the drainage frame plate 362 can limit and guide the water and sediment. The inclined angles of the drainage frame plate 362 and the extension baffle 365 facilitate the outward flow of the water and sediment. When it is necessary to remove the enclosure plate 10, the bolt 363 can be rotated so that it no longer fixedly connects the drainage frame plate 362 and the enclosure plate 10. Then, the drainage frame plate 362 can be removed outward, making the enclosure plate 10 without the drainage frame plate 362 more convenient for transportation and storage. Further, the limit stop rod 360 also needs to be removed from the corresponding mounting bracket 30, so that the mounting bracket 30 without the limit stop rod 360 is more convenient for transportation and storage together with the support connecting plate 25.

[0070] During operation: First step, according to the specifications of the bridge pile foundation to be built, an appropriate number of enclosure plates 10, vertical connectors 13 and parallel connectors 12 are adopted. Then, the enclosure plates 10, vertical connectors 13 and parallel connectors 12 are assembled into a rectangular foundation well enclosure 1. Then, the support plate 22 on the vertical connecting plate 100 is unfolded outward, and the support plate 22 is fixed through the connecting plug rod 23, the connecting plate 24 and the support connecting plate 25, so as to play a role in supporting the corners of the foundation well enclosure 1. Then, the connecting unit 26 is used to lock and fix the connecting plate 24 and the corresponding support connecting plate 25.

[0071] Step 2: Set the conveyor belt 34 with the nesting mechanism on the outer sides of the pulleys 33 at the upper and lower ends of the support connecting plate 25, and enable the limit assembly 37 to limit the corresponding conveyor belt 34. Then insert the limit stop rod 360 into the corresponding mounting bracket 30, and install the drainage frame plate 362 with the return compression spring rod 364 and the extension baffle 365 in the corresponding drainage through groove 361 through the bolt 363. After that, install the insertion rod 11 at the lower ends of the surrounding plate 10, the limit arc strip 121, the limit inner strip 131, and the limit hook strip 132, and then install the assembled device in the river channel.

[0072] Step 3: Decide whether to assemble the buffer structure 4 according to the water flow velocity. If the buffer structure 4 is needed, assemble it. After that, set the assembled buffer structure 4 on the side of the base well enclosure 1 close to the water flow direction, and make the opening of the buffer structure 4 tightly abut against the base well enclosure 1, so as to complete the installation of the buffer structure 4. If the buffer structure 4 is not needed, this step can be omitted.

[0073] Step 4: Continuously drain the water inside the base well enclosure 1 through the drainage mechanism 3, so that the bridge pile foundation can be constructed inside the base well enclosure 1; when the present invention is no longer needed, operate the above steps in reverse and disassemble and transport away the present invention.
