Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet pile technology, and in particular to a sheet pile for foundation pit support with a control mechanism. Background Technology
[0002] Steel sheet piles are a type of high-strength, high-rigidity steel structural material commonly used in soil support and cofferdam construction. They possess excellent load-bearing capacity and ease of construction, playing a crucial role in foundation pit support.
[0003] Sheet piles are interconnected by interlocking edges to achieve continuous laying. When laying sheet piles, impact driving, vibratory driving, or vibratory impact driving are generally used. In order to ensure accurate pile positioning and reliable connection between piles, the pile support worker needs to manually adjust the pile position. However, the pile support worker usually does not have special pile support tools, which makes it difficult to control the bottom of the sheet piles. Furthermore, the interlocking points of the interconnected sheet piles need to be caulked to prevent water seepage, but caulking is very difficult in a confined space. Utility Model Content
[0004] This utility model addresses the deficiencies in the existing technology by providing a steel sheet pile for foundation pit support with a control mechanism.
[0005] This utility model is achieved through the following technical solution: A sheet pile for foundation pit support with a control mechanism includes a sheet pile body, filler material, and a control mechanism. The filler material is disposed inside the locking edge of the sheet pile body. The control mechanism is engaged at the bottom of the sheet pile body. The control mechanism includes a backing plate, a locking shaft, clamping claws, a pull plate, a telescopic rod, a handle, a grip, and a reference bar. The locking shaft is engaged inside the backing plate. The clamping claws are fixedly disposed at one end of the locking shaft. The pull plate is fixedly disposed at the other end of the locking shaft. The handle is fixedly disposed on the outside of the backing plate. The telescopic rod is disposed between the pull plate and the handle. The handle is disposed on the outside of the pull plate. The reference bar is fixedly disposed at the bottom of the backing plate.
[0006] In a preferred embodiment of this utility model, the filler is a water-swellable waterstop strip, the internal material of which is rubber and high-molecular inorganic water-absorbing and swelling material; The filler material is mainly used after the sheet piles are used. When water seepage occurs, the water will cause the water-absorbing and expanding material to react and fill the interlocking connection of the sheet piles, thereby effectively stopping the water. No subsequent caulking is required, reducing the amount of construction work and lowering the construction difficulty.
[0007] In a preferred embodiment of the present invention, one end of the clamping shaft passes through and extends to the outside of one side of the backing plate, and the clamping claw is disposed on the outside of one side of the backing plate, with its top end being inclined.
[0008] In a preferred embodiment of this utility model, the telescopic rod is a pneumatic telescopic rod, which is disposed at both ends of the pull plate and does not interfere with the handle; After the handle is loosened, the locking shaft can automatically reset, allowing the backplate and clamping claw to automatically separate.
[0009] In a preferred embodiment of this utility model, the compression between the handle and the gripper is greater than the length of the clamping shaft extending out of the backing plate, so that the backing plate and the clamping claw can clamp the bottom of the sheet pile body. This ensures that when pressure is applied to the handle, the backing plate and clamping claws can clamp the bottom of the sheet pile, thereby facilitating effective control of the sheet pile laying position.
[0010] In a preferred embodiment of this utility model, the reference strip is disposed on the bottom outer side of the backing plate, and its inner side is in contact with the outer surface of the steel sheet pile body.
[0011] The beneficial effects of this utility model are: The sheet piles used for foundation pit support are filled with water-swellable filler material. The filler material is placed inside the interlocking rings at the edge of the sheet piles. When water seepage occurs, the filler material will expand upon contact with water, thereby sealing the gaps and eliminating the need for workers to perform caulking. The control mechanism is mainly located at the bottom of the sheet piles, which facilitates workers to adjust the position of the sheet piles, thereby interlocking the sheet piles and laying them more straight.

[0014] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0015] like Figures 1-4 The sheet pile for foundation pit support shown includes a sheet pile body 1, filler material 2, and control mechanism 3. The filler material 2 is disposed inside the edge locking of the sheet pile body 1. The control mechanism 3 is locked at the bottom of the sheet pile body 1. The control mechanism 3 includes a backing plate 31, a locking shaft 32, a clamping claw 33, a pull plate 34, a telescopic rod 35, a handle 36, a grip 37, and a reference bar 38. The locking shaft 32 is locked inside the backing plate 31. The clamping claw 33 is fixedly disposed at one end of the locking shaft 32. The pull plate 34 is fixedly disposed at the other end of the locking shaft 32. The handle 37 is fixedly disposed on the outside of the backing plate 31. The telescopic rod 35 is disposed between the pull plate 34 and the handle 37. The handle 36 is disposed on the outside of the pull plate 34. The reference bar 38 is fixedly disposed at the bottom of the backing plate 31.
[0016] Specifically, the filler 2 is a water-swellable waterstop strip, the internal material of which is rubber and high-molecular inorganic water-absorbing and swelling material. One end of the clamping shaft 32 passes through and extends to the outside of one side of the backing plate 31. The clamping claw 33 is set on the outside of one side of the backing plate 31, and its top end is inclined. The telescopic rod 35 is a pneumatic telescopic rod, which is set at both ends of the pull plate 34 and does not interfere with the handle 36. The compression between the handle 36 and the handle 37 is greater than the length of the clamping shaft 32 extending out of the backing plate 31, so that the backing plate 31 and the clamping claw 33 can clamp the bottom of the sheet pile body 1. The reference strip 38 is set on the outside of the bottom of the backing plate 31, and its inner side is in contact with the outer surface of the sheet pile body 1.
[0017] In this embodiment, the edge of the sheet pile body 1 is a locking buckle, and a groove is provided inside the locking buckle. The groove is filled with a filler material 2, which is rubber and a polymer inorganic water-absorbing and expanding material. When water seepage occurs at the connection of the sheet pile body 1, the filler material 2 absorbs water and expands automatically, thereby automatically filling the gap at the locking buckle connection position, effectively sealing the gap and reducing water seepage. This eliminates the need for workers to perform grouting and filling work, reducing labor intensity and enabling effective waterproofing and seepage prevention in the first instance.
[0018] Furthermore, when laying the sheet pile body 1, the pile driver lifts the top of the sheet pile body 1. The worker needs to control the movement of the bottom of the sheet pile body 1 to ensure that the sheet pile body 1 is laid straight and the locking connection is reliable. At this time, the worker only needs to hold the handle 37 and hook his fingers on the handle 36 to lock the bottom of the sheet pile body 1 between the backing plate 31 and the clamping claw 33, and apply pressure to the handle 36 to compress the telescopic rod 35. The clamping claw 33 and the backing plate 31 clamp the bottom of the sheet pile body 1, which can control the adjustment of the bottom of the sheet pile body 1. The reference strip 38 is placed against the outside of the already erected sheet pile body 1 to make it fit against the outside of the sheet pile body 1, thereby effectively ensuring that the erected sheet pile body 1 is straight and ensuring the connection effect and laying reliability of the sheet pile body 1.
