Problems solved by technology

However, when the subway station is in the suburbs, the surrounding environment of the foundation pit is relatively simple, and relatively large deformation of the enclosure structure is allowed without increasing the thickness of the enclosure structure. The current design widely applies the inertia of urban subway stations to strictly control deformation, and it is lack of determining different supports according to different environments. The action of implementing the new development concept in order to implement the new development concept, resulting in waste of materials and high carbon emissions

Embodiment 1

[0034] This embodiment provides a full recovery support system for the temporary components of the foundation pit of the subway station, especially suitable for suburban subway stations, such as figure 1 , figure 2 and Figure 4 As shown, including the purlin 3 and the composite pile 4, the purlin 3 and the composite pile 4 are arranged on the outside of the end well 2 at both ends of the subway station 1, wherein the purlin 3 is arranged on the inside of the composite pile 4, and the composite pile 4 is arranged on the retaining The inner side of the earth wall 5 is in contact with the earth retaining wall 5 to share the earth pressure, which can reduce the thickness of the earth retaining wall 5 and save resources.

[0035] Further, such as figure 2 As shown, the composite pile 4 includes a steel pipe pile 4.1, a steel sheet pile 4.2 and a connecting member 4.3, wherein the steel pipe pile 4.1 and the steel sheet pile 4.2 are arranged alternately, and the two sides of th...

Embodiment 2

[0044] This embodiment provides a construction method for the full recovery support system of the temporary components of the foundation pit of the subway station. The full recovery support system of the temporary components of the foundation pit of the subway station adopts the structure described in Embodiment 1, including the following steps:

[0045] Step 1: According to the soil conditions around the foundation pit of the end well of the subway station, the numerical simulation method is used to establish the composite pile model; and the deformation of the composite pile is calculated in combination with deformation compensation to obtain the inclination angle of the composite pile. According to the construction conditions of the foundation pit, determine the model of the composite pile, the length of the pile, the number and distribution scheme of the steel purlins and steel supports.

[0046] Since the construction envelope of the subway station is usually designed as a...

Abstract

The invention discloses a subway station foundation pit temporary component full-recovery supporting system and a construction method, and belongs to the technical field of subway station foundation pit construction.The technical scheme is that the subway station foundation pit temporary component full-recovery supporting system comprises surrounding purlins and combined piles, the combined piles comprise steel pipe piles and steel sheet piles which are arranged in a staggered mode, and the steel sheet piles make contact with one side of a connecting component; and the other side of the connecting component is detachably connected with the enclosing purlin. The combined pile structure convenient to disassemble is adopted, and full recovery of temporary components can be achieved; and on the basis of the idea of deformation compensation, excavation deformation is predicted, combined pile small-angle construction is conducted, excavation deformation is compensated, investment is reduced, the construction period is shortened, and construction safety is improved.

Description

technical field [0001] The invention relates to the technical field of subway station foundation pit construction, in particular to a fully recovered support system and construction method for temporary components of a subway station foundation pit. Background technique [0002] The concept of temporary is generally followed in the design of subway stations. For example, vertical components such as ground connection walls and support piles are used as enclosure structures. After the completion of the station, the vertical components are left underground, which wastes materials. The support members generally use concrete supports or steel pipe supports, and the concrete supports need to be demolished by blasting, which pollutes the environment; the steel pipe supports generally have a high density and the construction space is limited. At present, subway stations built according to the temporary concept have problems such as wasting materials and polluting the environment. ...
