Embodiment Construction

[0060] Such as figure 1 and figure 2 As shown, the construction method of the pipe row and pipe curtain of the present invention takes the pipe row 1 as the construction unit, and simultaneously jacks up to carry out the construction of the pipe curtain structure, wherein the pipe row 1 is composed of a group of steel pipes arranged side by side, and the adjacent steel pipes are connected by The components are connected by 3, and the number of steel pipes in each group is not less than 2.

[0061] The connecting member 3 connected between adjacent steel pipes is selected from the existing male lock and female lock connecting members used in conjunction with each other. The male connecting member includes two back-facing and parallel angle steels, which are respectively welded and fixed on the outer wall of the steel pipe. , parallel and non-overlapping settings; the female lock includes two buckle-oriented and parallel angle steels, which are respectively welded and fixed on...

Abstract

The invention relates to the technical field of underground space construction, and discloses a pipe curtain construction method based on pipe banks. According to the pipe curtain construction method based on the pipe banks, the pipe banks are used as the construction unit and jacked at the same time for constructing a pipe curtain structure, each pipe bank is formed by arranging a set of steel pipes side by side, every two adjacent steel pipes are connected through a connecting component, and the number of the steel pipes in each set is not smaller than two. By adoption of the pipe curtain construction method based on the pipe banks, the construction efficiency is high, the jacking tendency can be controlled highly, jacking deviation can be rectified easily, and the construction precision is high.

Description

technical field [0001] The invention relates to the technical field of underground space construction, in particular to a construction method for a pipe row and pipe curtain. Background technique [0002] At present, there are more and more developments and utilizations of underground space in our country. General large-scale underground spaces, such as subways, stations and other facilities, adopt trenchless construction technology. The pipe curtain construction method adopts the small-diameter pipe curtain construction method to push the pipe curtain steel pipes around or in the arch of the proposed underground space, and the steel pipes are connected by locks to form a closed or semi-closed curtain structure. Constructing large-span section underground excavation projects has many advantages such as small ground disturbance, low engineering cost, short construction period, and good water-stop performance. It is suitable for dense urban buildings, heavy ground traffic, oth...
