Assembly type power transmission line anchor rod static pressure miniature pile foundation and construction method thereof

Abstract

The invention relates to an assembly type power transmission line anchor rod static pressure miniature pile foundation. The foundation comprises a first connecting main body and second connecting mainbodies, wherein the first connecting main body and the second connecting main bodies form a square bearing table, the first connecting main body is in a cross shape, and is formed by splicing the same four parts in a mutual embedding mode, the number of the second connecting main bodies is four, the four second connecting main bodies are distributed in a crossed grid of the first connecting mainbody and are spliced with the first connecting main body in a mutual embedding mode, each second connecting main body is in a concentric square shape and is formed by splicing two parts in a mutual embedding mode, and the two sides of each splicing joint between the side wall of the first connecting main body and the side wall of the corresponding second connecting main body are connected and fixed through a connecting steel plate, a pre-buried screw rod and a nut. All components of the assembly type power transmission line anchor rod static pressure miniature pile foundation with the design are prefabricated in factories and assembled on site, the construction is simple, convenient and fast, the influence on the environment is small, manpower and material resources are saved, and full-mechanical construction of the power transmission line foundation is realized.

Description

technical field [0001] The invention relates to the technical field of foundation engineering construction, in particular to an assembled power transmission line bolt static pressure miniature pile foundation and a construction method thereof. Background technique [0002] my country has a vast territory, and the transmission line construction project is huge. The traditional transmission line pile foundation is mainly formed by on-site pouring. When the pile foundation is poured on site, the construction machinery will drill holes on site, the steel bars will be bound on site, and the concrete will be mixed on site, which has the disadvantages of large manpower consumption, large noise pollution, long construction period, and high cost. Excessive thickness of sediment, collapse of holes, and rapid pile extraction lead to problems such as necking of the pile body, making it difficult to guarantee the quality of the pile body. At the same time, a large amount of mud garbage w...

AI Technical Summary

Problems solved by technology

At present, anchor static pressure micro piles are widely used in the field of housing construction, especially suitable for small and medium-sized industrial and civil buildings with small and scattered loads. It is not only used for foundation reinforcement of new projects, but also for the foundation of existing projects. It is also widely used in foundation pit and slope reinforcement engineering, but the anchor static pressure micro pile is less used in transmission line engineering
