The pipe gallery The ground on both sides of the main body is provided with sewage wells outside the corridor, and the sewage wells on the top of the corridor and the sewage wells outside the corridor are connected by the main sewage main pipe at the bottom of the corridor installed at the bottom of the main body of the pipe gallery.

Wherein, the main sewage main pipe at the bottom of the corridor is arranged in the sewage pipe laying box culvert, and the sewage pipe laying box culvert is arranged at the bottom of the main body of the pipe gallery, and the width and height of the inner cavity cross section of the sewage pipe laying box culvert are larger than the diameter of the main sewage pipe at the bottom of the gallery, and the gap between the inner cavity of the sewage pipe-laying box culvert and the main sewage main pipe at the bottom of the gallery is filled with coarse sand;

The main sewage main pipe at the bottom of the corridor is located on the pipe body of the main body of the pipe gallery. The vertical main pipe in the corridor is connected with the sewage well on the top of the corridor. The vertical main pipe in the corridor is provided with a four-way connection. The vertical main pipe in the gallery is connected with the sewage branch pipe in the gallery by the cross.

Preferably, the main body of the pipe gallery includes a gas cabin, a comprehensive cabin, and an electric cabin; the corridor top sewage well is arranged on the ground above the comprehensive cabin.

Preferably, the elevation of the main sewage pipe at the bottom of the gallery is lower than the elevation of the outer roof of the main body of the utility gallery.

The beneficial effects of the utility model:

The utility model realizes the flexible contact between the main sewage pipe at the bottom of the gallery and the structure of the pipe gallery by arranging the existing main sewage main pipe at the bottom of the gallery in a sewage pipe-laying box culvert filled with coarse sand, which can reduce the bending of the main sewage main pipe at the bottom of the gallery even the risk of breaking.

Moreover, it is more convenient for the exhaust of the sewage pipes in the corridor to be connected to the sewage branch pipes in the corridor through the four-way connection.

The conception, specific structure and technical effects of the present utility model will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, characteristics and effects of the present utility model.
