Material saving device and method for supporting transverse stress pile

Abstract

The invention relates to the field of foundation pit supporting or slope supporting engineering, in particular to a material saving device and a method for supporting a transverse stress pile. The material saving device comprises more than one pile body, wherein the pile bodies are distributed side by side and are connected with a bidirectional support; the bidirectional support is connected with a steel strand system; the steel strand system comprises more than one son steel strand; each son steel strand comprises a multi-strand branch steel strand; the branch steel strand is divided from the son steel strand part and is fixedly connected with the bidirectional support. The material saving device has the beneficial effects that the construction time and the construction space can be greatly saved and the base slot excavation and the backfill earthwork volume are reduced compared with the conventional construction technology, the using amount of a material in the construction process is reduced, special reinforcing frameworks such as channel beam are not required, the material is saved by 95 percent, but the reinforcing effect is better, the stress is uniform and the steel strand is used for reinforcing the entire body of the more than one pile bodies in a separate mode, so that the problem of non-uniform stress of the steel strand in the conventional construction process is avoided.

Description

technical field [0001] The invention relates to the field of foundation pit support or slope support engineering, in particular to a material-saving device and method for supporting transversely stressed piles. Background technique [0002] In the construction of foundation pit support and slope treatment engineering, anchor-stayed pile support system has been widely used. The traditional anchor-pile system is a process in which the anchor cable transmits force to the anchorage, the anchorage transmits force to the waist beam, and the waist beam transmits force to the supporting pile, so as to achieve the purpose of strengthening the soil and ensuring the stability of the slope. The disadvantage of this method is that it is necessary to manufacture and install the waist beam, which leads to a large waste of materials, high construction difficulty, and high work intensity, which increases the construction risk and construction cost. Up to now, the waist beam is still indispen...

Problems solved by technology

The disadvantage of this method is that it is necessary to manufacture and install the waist beam, which leads to a large waste of materials, high construction difficulty, and high work intensity, which increases the construction risk and construction cost. Up to now, the waist beam is still indispensable as a force transmission component in the anchor-stayed pile support system. a part of

The traditional method of anchor-stayed pile support system results in a large construction area and a large amount of excavation and backfilling. In addition to increasing the cost of the project, the increase in the amount of spoil engineering also causes greater pollution to the environment
