Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] see Figure 1 to Figure 11 , a two-wall-in-one underground pipe gallery construction method is characterized in that it comprises the following steps:

[0034] S1. Production of prefabricated parts: making reinforced concrete prefabricated sheet piles and reinforced concrete prefabricated roof 1;

[0035]S2. Fabrication of the outer wall of the underground pipe gallery: two grooves are formed on the foundation to accommodate the walls on both sides of the pipe gallery, and waterproof and solidified soil slurry is injected into the trench. The trench is filled with waterproof and solidified soil paddle while digging. The composition of the waterproof and solidified soil slurry is water and solids mixed in the water. The solids are the soil and soil hardener at the construction site. The mass of the soil hardener is 15%-30% of the mass of the soil...

Abstract

The invention relates to a construction method of a two-wall-in-one underground pipe gallery, comprising the following steps: S1, making prefabricated parts; S2, making the outer wall of the underground pipe gallery; S4, making the floor of the underground pipe gallery; S5: inside the underground pipe gallery construction. The invention provides a two-wall-in-one construction method for an underground pipe gallery, which solves the problem of waste of resources caused by not realizing the two-wall integration in the construction process of the existing underground pipe gallery.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method of a two-wall-in-one underground pipe gallery and a two-wall-in-one underground pipe gallery structure. Background technique [0002] Before the excavation of the foundation pit in the underground space, it is generally necessary to design and construct the enclosure structure (underground diaphragm wall) around the foundation pit. The underground diaphragm wall has a cast-in-place structure and an assembled underground diaphragm wall. The existing underground The continuous cavity can only be used as a water and earth retaining wall during the excavation of the foundation pit. After the excavation of the foundation pit is completed, it is necessary to cast a weighing wall in the foundation pit to support the building on the ground, that is, the existing building Objects such as the wall part of the pipe gallery need to construct two walls, and the tw...
