Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a Larsen steel sheet pile permanent enclosure structure system. Background Art

[0002] Larsen sheet piles, also known as U-shaped steel sheet piles, are commonly used in the construction industry for cofferdams or temporary retaining structures in construction projects such as ditches. After trench construction is completed, the Larsen sheet piles are removed. Because Larsen sheet piles are composed of a number of interlocking, positively and negatively spaced Larsen steel sheets, their surfaces are concave and convex, with no flat surfaces, making them difficult to use as permanent retaining structures. For example, in construction environments where the clear spacing between piles is only approximately 650mm, using Larsen sheet piles as a permanent retaining structure would result in contact between the Larsen sheet piles and the basement slab. Foundation pit waterproofing requirements necessitate waterproofing of both the basement slab and the inner surfaces of the Larsen sheet piles. However, due to its thickness and weight, the 4mm thick pre-paved waterproofing membrane with a polymer-modified asphalt polyester base cannot be laid and adhered to the uneven surface of the Larsen sheet piles to achieve waterproofing, thus hindering their use as a permanent retaining structure. Utility Model Content

[0003] The purpose of the utility model is to provide a Larsen steel sheet pile permanent enclosure structure system to solve the problem of how to use Larsen steel sheet piles as a permanent enclosure structure system in a construction environment where the net spacing between engineering piles is small.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a Larsen steel sheet pile permanent enclosure structure system, comprising:

[0005] Steel bars are arranged horizontally and welded at intervals vertically on each concave surface of the inner surface of the Larsen steel sheet pile;

[0006] Wooden squares are vertically arranged inside the steel bars in each concave surface of the inner surface of the Larsen steel sheet pile, and the intersection nodes of the wooden squares and the steel bars are tied and fixedly connected;

[0007] A wooden formwork is laid on the outside of the steel bars in each concave surface of the inner surface of the Larsen steel sheet pile, and the wooden formwork is fixed to the wooden square by nails, so that the wooden formwork blocks each concave surface of the inner surface of the Larsen steel sheet pile, so that each concave surface forms a hollow cavity through the formwork, and the outer surface of the wooden formwork and each convex surface of the inner surface of the Larsen steel sheet pile are in the same plane, so that the inner surface of the Larsen steel sheet pile forms a planar structure;

[0008] Waterproof membrane, laid on the inner surface of Larsen steel sheet pile;

[0009] Quicksand is densely filled in the cavities of each concave surface on the inner surface of the Larsen steel sheet pile.

[0010] Furthermore, in the Larsen steel sheet pile permanent enclosure structure system provided by the present invention, the wooden squares vertically arranged inside the steel bars in each concave surface of the inner surface of the Larsen steel sheet pile are two spaced-apart wooden squares.

[0011] Furthermore, in the Larsen steel sheet pile permanent enclosure structure system provided by the present invention, the steel bars and the timber are fixedly connected by binding with straps or steel wires.

[0012] Furthermore, in the Larsen steel sheet pile permanent enclosure structure system provided by the present invention, the waterproof membrane is a polymer-modified asphalt polyester-based waterproof membrane.

[0013] Furthermore, in the Larsen steel sheet pile permanent enclosure structure system provided by the present invention, the vertical spacing distance between the steel bars on each concave surface of the inner surface of the Larsen steel sheet pile is 1000 mm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model provides a Larsen steel sheet pile permanent enclosure structure system, which forms a planar structure from the concave surface of the inner surface of the Larsen steel sheet pile by welding steel bars, installing wooden planks, and laying templates, so that the inner surface of the Larsen steel sheet pile is formed from a concave and convex shape, so that waterproof membranes can be smoothly laid on the inner surface of the Larsen steel sheet pile with the planar structure to achieve waterproofing of the inner side of the pit, thereby realizing the use of the Larsen steel sheet pile as a permanent enclosure structure.

[0016] The Larsen steel sheet pile permanent enclosure structure system provided by the utility model densely fills the cavities of the concave surfaces on the inner surface of the Larsen steel sheet pile with quicksand, thereby improving the strength of the concave surfaces on the inner surface of the Larsen steel sheet pile. The Larsen steel sheet pile can improve the structural strength, bearing capacity and anti-deformation ability of the permanent enclosure structure system, and prevent the waterproof membrane from being damaged after being subjected to force, thereby preventing the Larsen steel sheet pile from leaking when used as a permanent enclosure structure system.

[0017] The Larsen steel sheet pile permanent enclosure structure system provided by the utility model is suitable for construction environments with narrow spaces such as small net spacing between engineering piles. Larsen steel sheet piles are used as permanent enclosure structures to facilitate the construction, layout and adjustment of the enclosure structure.

[0018] The Larsen steel sheet pile permanent retaining structure system provided by the utility model densely fills the cavities of each concave surface of the inner surface of the Larsen steel sheet pile with quicksand instead of pouring concrete.
