Underground engineering consequent construction method and structure

Abstract

The invention discloses an underground engineering consequent construction method and structure. When an upper layer wale of a to-be-built building is casted, connectors used for connecting vertical large diameter rebar are pre-embedded at the bottom of the building, soft layers are arranged on the outer parts of the connectors, and when the upper layer wale is casted to reach the designed strength of the to-be-built building, the soft layer is chiseled away; earthwork is excavated to the horizontal surface of the bottom of a lower layer wale; the vertical large diameter rebar is well prepared, the connectors are mounted at the bottom of the vertical large diameter rebar, and the top end of the vertical large diameter rebar is mounted in the connectors located at the bottom of the upper layer wale; and the connectors mounted at the bottom end of the vertical large diameter rebar is pre-embedded in the inner bottom of the building, the soft layers are arranged at the edges of the side surfaces of the connectors, and mounting of the vertical large diameter rebar between the upper layer wale and the lower layer wale is completed. According to the underground engineering consequent construction method and structure, the vertical large diameter rebar and the rebar connectors are pre-embedded when the wales are casted, the problem that the vertical large diameter rebar of the main body structural side wall is difficult to mount is solved, and the construction difficulty is lowered.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of underground engineering construction, and in particular relates to an underground engineering sequential construction method and structure. [0003] 【Background technique】 [0004] With the rapid development of urban construction and the increase of population density, various types of underground projects and large-scale deep foundation pit projects are also increasing. In order to ensure the rapid and safe construction of deep foundation pits, excavate to the bottom of deep foundation pits as soon as possible and quickly seal the bottom , it is more suitable to adopt the straight method of construction. [0005] The straight method is an unconventional construction method, which is generally adopted in special circumstances such as deep foundations, complex geology, and high groundwater levels. Construction of underground continuous wall or other supporting structures along the axis of the base...

Problems solved by technology

[0009] The purpose of the present invention is to provide a construction method and structure of the underground engineering in accordance with the construction method. By pre-burying the vertical large-diameter steel bar and the steel bar connector when the waist beam is poured, it solves the problem of difficult installation of the vertical large-diameter steel bar on the side wall of the main structure. problem, reduce construction difficulty
