Novel steel plate pile even wall

Abstract

The invention discloses a novel steel plate pile even wall and relates to the technical field of building engineering devices, in particular to a pile body and a fixing rack. An operation opening is formed in the top of the pile body, a bayonet groove is formed in the inner side of the operation opening, and a cover plate is installed in the middle of the bayonet groove; the cover plate is embedded in the bayonet groove, a rope penetration hole is formed in the upper surface of the cover plate, and vent holes are formed in the left and right sides of the rope penetration hole; a connection hole is formed in the lower portion of the operation opening, a fixing hole is formed in the outer side of the fixing rack, and the fixing rack is located at the outer side of the connection hole. According to the novel steel plate pile even wall, through a sealing structure formed by the cover plate and the bayonet groove, the operation opening of the top of the pile body is sealed, the cover plateis embedded in the bayonet groove, and the situation can be prevented that soil or other impurities fall in a center cylinder of the inner side of the pile body; through normal application of an interference device, the wall is damaged, and the reliability and safety of the wall are conveniently improved.

Description

Technical field [0001] The invention relates to the technical field of construction engineering devices, in particular to a new type of steel sheet pile ground connecting wall. Background technique [0002] The steel sheet pile is a kind of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and compact steel structure with a retaining wall or a water retaining wall. The general steel sheet pile is a type of steel with a lock , Its cross-sections are straight, trough, Z-shaped, etc., and there are various sizes and interlocking forms. The common ones are Larsen, Lacvanner, etc. The steel sheet pile has high strength and is easy to drive into hard soil. It can be constructed in deep water. If necessary, diagonal support is added to form a cage. It has good waterproof performance and can be formed into cofferdams of various shapes as required and can be reused many times. Therefore, it has a wide range of uses. [00...

AI Technical Summary

Problems solved by technology

[0003] Existing steel sheet piles are usually a piece of flat section steel, and its connection structures are generally arranged on the left and right sides. When used, they can only be connected in a straight line. In non-linear areas and right-angle turns, it is difficult to completely connect, and the bonding strength and sealing performance are relatively poor. In addition, the steel sheet pile needs to be buried in the soil when it is used. The weight of the steel sheet pile is limited and the center of gravity cannot be changed. The resistance is relatively large when buried. At the same time, the general steel sheet pile can only be buried by external pile drivers and other auxiliary devices, which is flexible lower sex

[0004] A new type of steel sheet pile is disclosed in CN207452881U, a Chinese utility model patent application publication. Although the new type of steel sheet pile is equipped with a cylindrical main steel sheet pile assembly, it has good cross-sectional properties and bending resistance, and it is different from the linear auxiliary steel sheet pile. The combination improves the bending resistance and impact resistance of the formed steel sheet pile wall. However, the new steel sheet pile still only has a pair of symmetrically arranged connecting components, which has the disadvantage of being difficult to connect completely with non-linear areas and right-angle turns.
