Embodiment Construction

[0079] The following is attached Figure 1-3 The application is described in further detail.

[0080] The embodiment of the present application discloses a pipe gallery construction process, and the process steps of the pipe gallery construction process are as follows:

[0081] S1, measurement and setting out;

[0082] S2. Trench excavation: For positions where the excavation depth is not greater than 8m, use slopes and soil nail walls to support the slope; for positions where the excavation depth is greater than 8m and the slope distance is limited, use Larsen steel plates piles or bored piles for support;

[0083] S21. Measure the centerline of the setting-out and fixed-pipe gallery;

[0084] S22, foundation pit precipitation and support;

[0085] S23. According to the center line of the pipe gallery and the requirements of the grading coefficient, set out the sideline of the trench excavation of the pipe gallery;

[0086] S24, foundation pit excavation;

[0087] S25. ...

Abstract

The invention relates to the field of building construction, and particularly relates to a pipe gallery construction process. The pipe gallery construction process comprises the following process steps of S1, surveying and setting out; S2, groove excavation; S3, cushion layer construction and bottom plate waterproof construction, specifically, S31, concrete cushion layer pouring; S32, base waterproof treatment; S4, pipe gallery steel bar and concrete pouring; S5, formwork engineering; S6, concrete pouring, specifically, S61, layered pouring; S62, concrete pouring; S63, concrete curing; S7, deformation joint and construction joint treatment; S8, wall body and top plate waterproof treatment; and S9, groove backfilling. According to the pipe gallery construction process, through a concrete cushion layer, a cement mortar leveling layer, a waterproof coiled material and a waterproof coiled material, base waterproof treatment is achieved, the influence of underground water seepage on pipe gallery construction is reduced, the waterproof performance of a base is enhanced, subsequent construction of a pipe gallery is facilitated, and the overall efficiency of pipe gallery construction is improved; and meanwhile, through a concrete pouring process, holes in the concrete pouring process are reduced, and the overall strength of the pipe gallery is improved.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a construction technique of a pipe gallery. Background technique [0002] The pipe gallery is a comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports and hoisting ports Municipal public facilities and monitoring systems; the pipe gallery is mainly composed of columns, beams and trusses of steel structure or reinforced concrete structure, which can be divided into single-layer or multi-layer according to the type, passable or impassable, etc. [0003] The Chinese patent with the application number 201710179208.8 discloses a construction process for the loess layer pipe gallery, which is constructed according to the following steps: excavate the loess coating to f...
