Description

Technical Field

[0001] This utility model relates to a steel sheet pile water-tight device for coastal areas. Background Technology

[0002] Foundation construction in coastal areas requires dewatering. In specific environments, traditional dewatering techniques cannot meet environmental requirements. Using sheet piles for support, especially at the corners, can easily lead to poor sealing at the joints. Under long-term erosion by groundwater, leakage can easily occur at the joints, rendering the dewatering ineffective. Utility Model Content

[0003] This invention provides a steel sheet pile water-tight device for coastal areas, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A coastal area steel sheet pile water-tight device, comprising

[0006] Walls;

[0007] Multiple sheet pile bodies are arranged at intervals along the circumference of the wall, and each sheet pile body is provided with an arc-shaped groove and a locking groove.

[0008] Connecting plate;

[0009] An angle assembly for connecting two adjacent sheet pile bodies at an angle, including a main board and a locking part, a curved part and a fitting part integrally formed on the main board;

[0010] The locking part is engaged and fixed with the locking groove, the curved part is fitted with the arc groove, and the fitting part abuts against the end face of the adjacent steel sheet pile body and seals the arc groove.

[0011] The junction of the arc-shaped groove, the locking groove, and the corner assembly forms a sealed, watertight structure.

[0012] The beneficial effects of this utility model are:

[0013] (1) The coastal area steel sheet pile water-tight device is constructed by arranging multiple steel sheet pile bodies at intervals along the circumference of the wall and connecting adjacent steel sheet pile bodies with an integrally formed corner assembly. The locking part of the corner assembly is fixedly engaged with the locking groove of the steel sheet pile body, the curved part is tightly fitted with the arc groove, and the fitting part abuts against the end face of the adjacent steel sheet pile body and seals the arc groove, forming a triple sealing structure. At the same time, the spring steel sheet and nickel-titanium alloy sheet set in the arc groove provide temperature-adaptive elastic clamping force. The expansion waterstop strip embedded in the locking groove and the quick-setting waterproof slurry filled in the reserved channel further enhance the sealing effect. Combined with the drainage pipe embedded in the graded crushed stone layer between the connecting plate and the wall, it not only achieves excellent water-tight performance and can effectively resist tidal changes and water pressure impact to prevent leakage, but also has the advantages of convenient construction, simple maintenance, and strong durability, which can significantly extend the service life of the structure and reduce maintenance costs.

[0025] Reference Figure 1-3 As shown, a steel sheet pile water-tightening device for coastal areas includes...

[0026] Wall 10; connecting plate 30; a graded crushed stone layer is filled between wall 10 and the sheet pile body 20, and a drainage pipe is pre-embedded in the graded crushed stone layer.

[0027] Multiple sheet pile bodies 20 are arranged at intervals along the circumference of the wall 10. The sheet pile body 20 is provided with an arc groove 200 and a locking groove 202.

[0028] The corner assembly 40 is used to connect two adjacent sheet pile bodies 20 at a corner. It includes a main board 400 and a locking part 404, a curved part 406, and a fitting part 408 integrally formed on the main board 400. The locking part 404 is engaged and fixed with the locking groove 202. The curved part 406 is fitted with the arc groove 200. The fitting part 408 abuts against the end face of the adjacent sheet pile body 20 and seals the arc groove 200. A rubber sealing gasket is sandwiched between the fitting part 408 and the end face of the sheet pile body 20. The rubber sealing gasket is fixed by pre-tightening bolts. The mating points of the arc groove 200, the locking groove 202, and the corner assembly 40 form a sealed watertight structure.

[0029] A spring steel sheet 2002 is provided on the arc-shaped groove 200; the free end of the spring steel sheet 2002 is inclined toward the groove opening of the arc-shaped groove 200 to form an elastic pressing structure.

[0030] Furthermore, a nickel-titanium alloy sheet is embedded in the arc-shaped groove 200. Its initial shape is flat, but it bends and presses the curved part 406 when exposed to seawater temperature, thus achieving temperature-adaptive sealing.

[0031] An expansion stop strip 2020 is pre-embedded on the inner side of the lock groove 202, forming a reserved channel 2022 inside the lock groove 202. The reserved channel 2022 is filled with quick-setting waterproof slurry.

[0032] A reserved opening 402 is formed at the top of the main board 400. The reserved opening 402 is connected to the reserved channel 2022 to facilitate subsequent grouting. The reserved opening 402 is funnel-shaped and has a sealing cap connected by threads.

[0033] Furthermore, a pressure sensor is pre-embedded in the reserved channel 2022. During grouting, polyurethane foam is injected through the reserved port 402. The sensor monitors the internal pressure in real time to ensure that the filling is dense.

[0034] The thickness of the main board 400 is greater than the thickness of the sheet pile body 20, and the backwater surface of the main board 400 is provided with reinforcing ribs.

[0035] The surface of the sheet pile body 20 is coated with an epoxy coal tar anticorrosive layer, and the corner component 40 is a one-piece stainless steel casting.

[0036] Working principle: Multiple sheet pile bodies 20 with epoxy coal tar anticorrosive coating are arranged circumferentially along the wall 10 and connected by stainless steel integral cast corner components 40 to form a closed loop structure. The curved part 406 of the corner component 40 is elastically engaged with the arc groove 200 of the sheet pile body 20 through inclined spring steel plates 2002. The locking part 404 is fixedly engaged with the locking groove 202 of the pre-embedded expansion waterstop 2020. At the same time, the fitting part 408 achieves end face sealing by tightening the rubber sealing gasket with bolts. The triple sealing structure, together with the quick-setting waterproof slurry injected into the reserved channel 2022, forms a continuous water-tight barrier. The graded crushed stone layer 30 and the pre-embedded drainage pipe 302 filling the space between the wall 10 and the sheet pile body 20 take into account the drainage needs, while the reinforcing rib design and thickened structure of the main board 400 ensure the compressive stability of the corner part.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
