Description

Technical Field

[0001] The utility model relates to the technical field of pile trusses, in particular to a pile truss for blocking dam breaches. Background Art

[0002] Pile truss is a relatively special structural form in engineering structures. The truss structure can enhance the lateral stability of the pile foundation, resist the scouring of water flow and lateral forces (such as wind loads, ship impact forces, etc.), and help to effectively seal the breached dam.

[0003] Most of the current pile trusses used to seal dam breaches have relatively simple structures, which are difficult to assemble and install, and often require a long working time. When put into use, the pile trusses have poor flexibility, which may affect the progress of the project and make it impossible to seal the breached dam in time.

[0004] Therefore, in view of the fact that the installation of the existing dam breach sealing pile truss combination is difficult, time-consuming and labor-intensive, a dam breach sealing pile truss can be designed. By combining and splicing, the splicing operation of each group of pile trusses can be optimized, the installation speed of the pile truss combination can be accelerated, the operation time can be saved, the progress of the dam breach sealing project can be shortened, and at the same time, the stability of the pile truss can be effectively guaranteed, thereby enhancing the practical value of the pile truss.
