AI Technical Summary
The gap between Larsen steel sheet piles is likely to cause water leakage and seepage. Existing methods such as using butter for sealing have high costs and high environmental pollution.
A steel support structure is designed, in which the sides of the steel sheet pile are curled to form hook grooves, and the sides of the adjacent steel sheet piles are interlocked in the opposite hook groove, and sealing grooves are provided on the inner wall of the hook groove to fill the seal to enhance sealing.
The steel sheet pile connection gap is sealed through sealing parts, which significantly enhances the sealing property, solves the problem of water leakage, and avoids environmental pollution from traditional methods.

Technical Field
[0001] The utility model relates to the technical field of support, in particular to a steel support structure with high use safety. Background Technique
[0002] The Larssen steel sheet pile is an important building material and is widely used in various engineering fields, especially in temporary or permanent building supports, retaining soil, retaining water, and retaining sand.
[0003] Adjacent two Larssen steel sheet piles are interlocked with each other, but there are often gaps at the interlocking parts, which will cause water leakage. Therefore, it is necessary to seal the gaps. The traditional method is to fill butter inside. However, butter not only has a high price cost but also can only be used once, and it also causes relatively large environmental pollution. Content of the Utility Model
[0004] The purpose of the utility model is to provide a steel support structure with high use safety to solve the problem of water seepage at the gaps between Larssen steel sheet piles as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A steel support structure with high use safety, including a plurality of steel sheet piles. The two side edges of the steel sheet piles are curled to form hook grooves. The side edges of adjacent two steel sheet piles are respectively engaged in the hook grooves of each other. A sealing groove is arranged on the inner wall surface of the hook groove, and the openings of the two mutually engaged sealing grooves coincide with each other and are jointly filled with a sealing member.
[0006] Preferably, the sealing member includes a T-shaped plate. The large head of the T-shaped plate is arranged downward. The side wall of the large head is attached to the inner walls of the two sealing grooves, and a sealing strip is filled between the side of the sealing groove in contact and the T-shaped plate. The sealing strip is fixed on the T-shaped plate. Through-type sludge discharge grooves are arranged at the upper and lower ends of the T-shaped plate. Two symmetrical sludge pressing heads are arranged at the large head end of the T-shaped plate, and the sludge pressing heads are in the shape of a right-angled triangular prism. The side wall of the right-angled surface is attached to the contact surface of the sealing groove, and the tip of the sludge pressing head is downward.
[0007] Preferably, the sealing strip is made of rubber material.
[0008] Preferably, the steel sheet pile is in a U shape.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] The steel support structure with high use safety of the utility model seals the connection gap between two steel sheet piles through the sealing member, enhances the sealing performance, and solves the problem of water leakage. Brief Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-4 , a steel support structure with high use safety, including a plurality of steel sheet piles 1. The two sides of the steel sheet pile 1 are curled to form a hook groove 2. The sides of two adjacent steel sheet piles 1 are respectively engaged in the hook groove 2 of the other. The steel sheet pile 1 is driven into the soil by a vibratory hammer for cofferdam construction. Preferably, the steel sheet pile 1 is in a U shape, and this shape can enhance the structural strength of the steel sheet pile 1.
[0018] The inner wall surface of the hook groove 2 is provided with a sealing groove 3, and the openings of two mutually engaged sealing grooves 3 coincide with each other and are jointly filled with a seal 4. The seal 4 is used to block the connection gap between the two steel sheet piles 1, enhance the sealing performance, and solve the water leakage problem.
[0019] Specifically, the seal 4 includes a T-shaped plate 41. The large head of the T-shaped plate 41 is arranged downward, and the side wall of the large head is attached to the inner wall of the two sealing grooves 3. A sealing strip 42 is filled between the fitting side of the sealing groove 3 and the T-shaped plate 41. Preferably, the sealing strip 42 is made of rubber material, and the rubber material can achieve good sealing and fitting.
[0020] The sealing strip 42 is fixed on the T-shaped plate 41. The upper and lower ends of the T-shaped plate 41 are provided with a through mud discharge groove 43. Two symmetric mud pressing heads 44 are arranged at the large head end of the T-shaped plate 41, and the mud pressing head 44 is in the shape of a right-angled triangular prism. The side wall of the right-angled surface is attached to the fitting surface of the sealing groove 3, and the tip of the mud pressing head 44 faces downward. When the mud pressing head 44 is inserted downward, the soil is squeezed into the mud discharge groove 42 to prevent the soil from hindering the sealing of the sealing strip 42.
[0021] Working principle: The utility model is a steel support structure with high safety. When in use, the steel sheet piles 1 are hammered into the soil by a vibrating hammer to form a cofferdam. Two adjacent steel sheet piles 1 are interlocked with each other, and a seal 4 is inserted into the sealing groove 3 at the interlocking position for sealing. The seal 4 is used to block the connection gap between the two steel sheet piles 1, enhance the sealing performance, and solve the leakage problem.
