Embodiment 1

[0043] Such as figure 1 , figure 2 As shown, a construction method for shallow foundation reinforcement of the present invention specifically includes the following steps:

[0044] Step 1: Construction preparation, determine construction related parameters

[0045] (1) Before the excavation of the built shallow foundation 3 (a number of fixed piles 4 are installed under the shallow foundation 3 for support), measure and position the line on the natural floor according to the uppermost edge of the earthwork excavation, and spread out the foundation earthwork with lime Dig the upper edge.

[0046] (2) Determine the bottom elevation of the built shallow foundation for mechanical earthwork excavation. Since there is a deep foundation floor around the built shallow foundation 3, the excavation is carried out on the basis of the deep foundation floor around the built shallow foundation 3 to the shallow foundation At the bottom elevation, carry out vertical section steel hoop 2 p...

Abstract

The invention discloses a construction method for shallow foundation reinforcement, and belongs to the technical field of building construction. The construction method specifically includes the following steps that (1) construction preparation is conducted, and construction related parameters are determined; (2) earth around a shallow foundation is excavated to a designed elevation; (3) layered construction of section steel hoops is conducted; (4) deep foundation earthwork layered excavation is constructed; (5) concrete support layered is conducted; and (6) deep foundation structure construction is conducted and deep and shallow foundation earthwork backfill construction is conducted. By the adoption of the technical scheme, the problems that when construction is conducted according to the sequence from shallow to deep in the prior art, the operation of reinforcing and supporting a built shallow foundation building is complex, the construction period is delayed, and the cost is wasted can be effectively solved. Meanwhile, the construction method for shallow foundation reinforcement is simple, high in safety and relatively low in construction cost.

Description

technical field [0001] The invention belongs to the technical field of building construction, and more specifically relates to a construction method for shallow foundation reinforcement. Background technique [0002] In the process of building construction, the traditional foundation construction sequence is usually "deep first, then shallow", which can effectively ensure the safety and stability of the foundation pit and surrounding structures. However, in actual construction, especially in the metallurgical construction process, due to various reasons such as the limited plane space of the construction site and construction organization arrangements, many construction processes adopt the construction sequence of "shallow first and then deep". If the shallow foundation is not strengthened and protected in the early stage, subsequent forced large-scale excavation will most likely cause displacement of the shallow foundation and its superstructure, resulting in greater econom...
