Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Example. A deep pit construction method, such as figure 1 shown. The method is to set a bottom beam at the bottom of the pit, and cast a buttress column 3 connected with the bottom beam at both ends of the bottom beam; . During casting, the bottom beam and the buttress column 3 are casted in one shot.

[0017] The pit structure formed by the above-mentioned deep pit construction method includes a cushion layer 6, on which a bottom beam is arranged, and buttress columns 3 are symmetrically arranged on the bottom beam; A wall panel 1 is arranged on the inner side of the pilaster 3 . The bottom beam includes a set of cross beams 4 and a set of longitudinal beams 5 , and the longitudinal beams 5 are connected with the most lateral beams 4 . The beams 4, longitudinal beams 5, buttress columns 3, bottom plate 2 and wall plate 1 are all ...

Abstract

The invention discloses a method for constructing a deep pit, and a pit structure. The method comprises the following steps of: arranging a bottom beam at the bottom of the pit, and casting wall-supporting columns which are integrally connected with the bottom beam at the two ends of the bottom beam; and casting a bottom plate and wall plates on the upper part of the bottom beam and the inner sides of the wall-supporting columns. The structure comprises a cushion layer (6) which is provided with the bottom beam, wherein the bottom beam is symmetrically provided with the wall-supporting columns (3); and the bottom plate (2) is arranged above the bottom beam, and the wall plates (1) are arranged on the inner sides of the wall-supporting columns (3). The bottom plate and the wall plates are not required to be thick compared with those in the prior art, so materials can be saved; the wall-supporting columns and the two ends of the bottom beam are integrally cast at one time, so the base of the wall-supporting columns is not required to be large and can have sufficient extrusion resistance; and the invention has the characteristics that: the pit structure is easy to design and calculate, and convenient to construct, and has a short construction period and high lateral soil pressure resistance.

Description

technical field [0001] The invention relates to a building structure, in particular to a deep pit construction method and a pit structure. Background technique [0002] In common pit design, generally only reinforced concrete is used to cast the bottom plate of the pit and the surrounding wall panels. This structure generally has no problem for shallow pits. However, for deeper pits, because the lateral soil pressure on the wall panels of the pits is relatively large, it is easy to squeeze the wall panels of the pits. In order to strengthen the anti-extrusion ability of the surrounding wall panels, buttress columns are usually arranged on the outside of the surrounding wall panels. The foundation of the current buttress columns is integrally cast with the bottom plate of the pit. Since the side soil pressure borne by the wall panels of the pit is all transmitted to the buttress columns, the bending moment at the bottom of the buttress columns is relatively large, which dire...
