Embodiment 2

[0029] Example 2, see image 3 , The prestressed purlin 3 is placed obliquely downward, and the rest are the same as in Example 1.

[0030] The foundation pit support structure with oblique supports and prestressed purlins described in this embodiment can greatly reduce the length and quantity of supports, and has large support rigidity, large span, small deformation, convenient construction, and the steel support part It can be recycled, and the safety factor of the foundation pit is high, which achieves the purpose of shortening the construction period and reducing the construction cost.

Abstract

The invention provides a foundation pit supporting structure with an oblique support and a pre-stress surrounding purlin. An enclosure wall and an oblique steel support are arranged inside the foundation pit supporting structure; the enclosure wall is connected with the pre-stress surrounding purlin which is connected with one end of the oblique steel support; and the other end of the oblique steel support is connected with a base plate of a foundation pit. The foundation pit supporting structure with the oblique support and the pre-stress surrounding purlin has the advantages of substantially reducing the length and number of supports, saving materials and construction costs and being short in construction period and large in construction space.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a foundation pit support structure with oblique supports and prestressed purlins. Background technique [0002] Foundation pit engineering in soft soil areas generally adopts the support type of horizontal inner support, but for large-scale foundation pit engineering, a huge support system is set up, the project cost is high, and dense inner supports affect the construction, and inner supports, supporting columns and column piles All three are expensive. Therefore, it is necessary to design a simple and feasible support type to meet the requirements of economical, safe and convenient construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing problems in the existing foundation pit support and provide a foundation pit support structure with oblique support beams. [0004] In order to solve ...
