Description

Technical Field

[0001] The present application relates to the technical field of waterproof structures for steel sheet pile construction, and specifically to a waterproof structure for steel sheet pile construction. Background Art

[0002] Steel sheet piles are a type of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and tight retaining wall or water retaining wall. When steel sheet piles are used for water retaining, the connection between two adjacent groups of steel sheet piles is prone to leakage and seepage. Therefore, a waterproof structure for steel sheet pile construction is needed to seal and waterproof the connection between the two steel sheet piles.

[0003] For example, a Chinese patent (publication number: CN214783816U) discloses a waterproof and airtight structure for steel sheet pile construction, including a steel sheet pile body, a reinforcement rod and a main sealing strip. A fixed clamp is arranged on the surface of the steel sheet pile body, and the reinforcement rod is fixedly connected by a fixed pin, so that the position stability of the steel sheet pile body can be enhanced; a main sealing strip and a secondary sealing strip are arranged at the connection of the steel sheet pile body, and the secondary sealing strip is connected with the sealing groove in an embedded manner, wherein a clamping groove is provided on the inner side wall of the sealing groove, and the clamping groove is fixedly connected with the clamping block by snapping, and a clamping spring is installed on the inner wall of the sealing groove, and the clamping spring is tightly fitted with the top end of the secondary sealing strip, and the clamping block is wedge-shaped and made of rubber, so that the main sealing strip and the secondary sealing strip are tightly fitted with the steel sheet pile body to form a two-layer waterproof structure, which effectively improves the waterproof effect.

[0004] However, the above search patent still has some shortcomings. Its sealing strip is fixed by a wedge-shaped rubber clamping block that is engaged with the clamping groove. If the hardness of the clamping block is high, it is not convenient to deform it and insert it into the clamping groove for installation and fixation, and it is not convenient for subsequent disassembly and recovery. If the hardness of the clamping block is low, the fixing effect is not firm enough, which is inconvenient to use. Therefore, a waterproof structure for steel sheet pile construction is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a waterproof structure for steel sheet pile construction, which has the advantages of easy installation and good fixing effect, and solves the problem that the device disclosed in the above-mentioned search patent is somewhat inconvenient to use.

[0015] Furthermore, a rectangular hole is provided on the back of the rectangular bin for the sliding plate to slide forward and backward, the extrusion plate is arranged inside the rectangular bin, and the sealing plate is located just in front of the connection between the two steel sheet pile bodies.

[0016] By adopting the above technical solution, it is convenient to seal by pushing the sealing plate backwards in cooperation with the steel sheet pile body to squeeze the sealing pad.

[0017] Furthermore, the bottom end of the screw extends to the inside of the rectangular bin and is rotatably connected to the inner bottom wall thereof, the plurality of extrusion blocks are equidistantly distributed up and down and are front-to-back opposite to the plurality of threaded blocks, and a round handle is fixed to the top end of the screw.

[0018] By adopting the above technical solution, it is convenient to complete the installation or disassembly of the device by rotating the screw rod through the provided round handle.

[0019] Furthermore, a slot for inserting a reinforcing rod is provided on the top surface of the reinforcing bin, the guide rod is a square rod, and a square hole for the guide rod to penetrate and be slidably connected to the connecting plate is provided on the front surface of the connecting plate.

[0024] 1. When using the waterproof structure for steel sheet pile construction, the rectangular bin and the back plate form a U-shaped structure and slide downward from the top of the two steel sheet pile bodies, so that the steel sheet pile body is clamped between the rectangular bin and the back plate, and then the extrusion assembly is controlled to push the extrusion plate backward to extrude the sealing plate and the sealing gasket tightly against the front of the steel sheet pile body to seal the connection. The installation operation is simple and convenient and the fixation is reliable, which ensures the waterproofness of the connection of the steel sheet pile body.

When in use, the rectangular bin 2 and the back plate 3 form a U-shaped structure and slide downward from the top of the two steel sheet pile bodies 1, so that the steel sheet pile body 1 is clamped between the rectangular bin 2 and the back plate 3, so that the waterproof mechanism can seal the connection between the two steel sheet pile bodies 1. The installation operation is simple and convenient, and the fixation is reliable, which ensures the waterproofness of the connection of the steel sheet pile body 1. At the same time, the extrusion component can be reversed, so that the device can be disassembled and recycled conveniently, which is more practical and more convenient to promote and use.

[0033] The opposite sides of the two steel sheet pile bodies 1 are bent backwards into an L shape, and a slot is provided on the back of the back plate 3 for the bent part of the steel sheet pile body 1 to pass through. The back plate 3 is an L-shaped plate, and the steel sheet pile body 1 is located between the rectangular bin 2 and the back plate 3. Such a structure makes it easy to form a U-shaped structure between the rectangular bin 2 and the back plate 3 to be stuck on the front and rear sides of the steel sheet pile body 1, thereby facilitating the installation of the waterproof mechanism.

[0034] See also Figure 1-3 The waterproof mechanism includes a sliding plate 401 slidably connected to the back of the rectangular bin 2, an extrusion plate 402 fixed on the front of the sliding plate 401, a sealing plate 403 fixed on the back of the sliding plate 401, a sealing gasket 404 fixed on the back of the sealing plate 403 and an extrusion component arranged inside the rectangular bin 2 for driving the sealing plate 403 to move forward and backward. When in use, the rectangular bin 2 and the back plate 3 form a U-shaped structure and slide downward from the top of the two steel sheet pile bodies 1, so that the steel sheet pile body 1 is clamped between the rectangular bin 2 and the back plate 3, and then the extrusion component is controlled to push the extrusion plate 402 to move backward, and the extrusion plate 402 pushes the sliding plate 401 to drive the sealing plate 403 to move backward, and then cooperates with the steel sheet pile body 1 to extrude the sealing gasket 404 to achieve a sealing effect.

A guide groove 409 for the guide block 408 to slide and connect is provided on the inner wall of the front side of the rectangular bin 2. When sealing is required, the screw 405 is rotated, and the screw 405 drives the plurality of threaded blocks 406 to cooperate with the guide block 408 and the guide groove 409 to slide in the up and down directions. When the threaded block 406 slides to be front-to-back relative to the extrusion block 407, it will push the extrusion block 407 to extrude backward, so that the extrusion block 407 pushes the extrusion plate 402 to move backward for sealing. When the device needs to be disassembled, the screw 405 is reversed so that the extrusion block 407 and the threaded block 406 are no longer front-to-back relative to each other, so that the sealing plate 403 loses the extrusion force and is convenient for disassembly.

[0037] In this embodiment, the bottom end of the screw rod 405 extends to the interior of the rectangular bin 2 and is rotatably connected to the inner bottom wall thereof. A plurality of extrusion blocks 407 are evenly distributed up and down and are opposite to a plurality of threaded blocks 406 front and back. A round handle is fixed to the top end of the screw rod 405.

[0038] See also Figure 1-4In this embodiment, the reinforcement mechanism includes a reinforcement bin 501 fixed on the front of the rectangular bin 2, a reinforcement rod 502 inserted on the left and right sides of the reinforcement bin 501, a guide rod 503 fixed between the front and rear inner walls of the reinforcement bin 501, a connecting plate 504 slidably connected to the outer peripheral wall of the guide rod 503, two limit rods 505 fixed on the front of the connecting plate 504, a limit plate 509 fixed to the top of the two limit rods 505 and a tension spring 506 fixed on the front of the connecting plate 504, two limit grooves 507 are provided on the back of the reinforcement rod 502, a sliding hole 508 is provided on the top surface of the reinforcement bin 501 for the limit rod 505 to slide back and forth, a slot is provided on the top surface of the reinforcement bin 501 for the reinforcement rod 502 to be inserted, the guide rod 503 is a square rod, and a square hole is provided on the front of the connecting plate 504 for the guide rod 503 to penetrate and be slidably connected thereto, and the sliding hole 508 is used for limiting The rod 505 slides back and forth inside it, and the tension spring 506 is sleeved on the outer peripheral wall of the guide rod 503. The front end of the tension spring 506 is fixed to the inner wall of the front side of the reinforcement bin 501. After the rectangular bin 2 is fixed to the front side of the steel sheet pile body 1, the limit plate 509 is slid backward, so that it drives the two limit rods 505 to move backward. The limit rod 505 drives the connecting plate 504 to slide backward along the guide rod 503 and stretch the tension spring 506. At this time, the reinforcement rod 502 is inserted into the slot at the top of the reinforcement bin 501, so that the left and right ends of the reinforcement rod 502 are respectively inserted into the two adjacent reinforcement bins 501, and then the limit plate 509 is released. The tension spring 506 pulls the connecting plate 504 to move forward, thereby driving the limit rod 505 to get stuck in the limit slot 507 to limit the left and right movement of the reinforcement rod 502. At the same time, the limit plate 509 moves forward to cover the slot to limit the up and down movement of the reinforcement rod 502 to achieve the limit fixing effect.

[0039] The working principle of the above embodiment is:

[0040] (1) When in use, the rectangular bin 2 and the back plate 3 are formed into a U-shaped structure and slid downward from the top of the two steel sheet pile bodies 1, and then the screw 405 is rotated. The screw 405 drives the multiple threaded blocks 406 to cooperate with the guide block 408 and the guide groove 409 to slide in the up and down direction.

[0041] (2) After the rectangular bin 2 is fixed on the front side of the steel sheet pile body 1, the limit plate 509 is slid backwards, so that it drives the two limit rods 505 to move backwards. The limit rods 505 drive the connecting plate 504 to slide backwards along the guide rods 503 and stretch the tension spring 506. At this time, the reinforcement rod 502 is inserted into the slot at the top of the reinforcement bin 501, so that the left and right ends of the reinforcement rod 502 are respectively inserted into the two adjacent reinforcement bins 501. Then the limit plate 509 is released, and the tension spring 506 pulls the connecting plate 504 to move forward, thereby driving the limit rod 505 to be stuck in the limit slot 507 to limit the left and right movement of the reinforcement rod 502. At the same time, the limit plate 509 moves forward to cover the slot to limit the up and down movement of the reinforcement rod 502 to achieve the limiting and fixing effect.
