Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an", and/or "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof;

for convenience of description, the words "up", "down", "left" and "right" in this disclosure, if any, merely indicate correspondence with up, down, left and right directions of the drawings themselves, and do not limit the structure, but merely facilitate description of the disclosure and simplify description, rather than indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the disclosure.

As introduced in the background art, the utility tunnel needs to be provided with two water collecting pits for drainage at the vertical low point and the position close to the firewall, and although the drainage requirement can be met, the construction difficulty and the investment of civil engineering and equipment are increased, and the cost performance and the practicability are lower; in order to solve the technical problem, the application provides a drainage structure for reducing the number of water collecting pits of a comprehensive pipe gallery.

The application provides a drainage structure for reducing the number of water collecting pits of a comprehensive pipe gallery, which comprises a drainage pipe, wherein the drainage pipe is of a U-shaped structure, and drainage ports are formed in the top surfaces of two protruding parts of the U-shaped structure along the direction of a pipeline; two longitudinal slopes are symmetrically arranged at the bottom of the U-shaped drain pipe structure along the central line.

Example 1

The drainage structure disclosed in the present embodiment will be further described with reference to fig. 1 to 2;

referring to fig. 1, a reduce drainage structure of utility tunnel sump pit quantity, including drain pipe 1, drain pipe 1 is U type structure, outlet 6 is seted up along the pipeline direction to two convex parts's of U type structure top surface, drain pipe 1 sets up in preventing hot wall 2 below, two convex parts of drain pipe 1U type structure are corresponding to respectively preventing hot wall 2 both sides and set up, its two rows of mouths of a river are corresponding to respectively preventing hot wall both sides, this drain pipe can stride across the fire prevention subregion, and the water that is detained at the drain pipe bottom plays the effect of separating adjacent fire prevention subregion, do not influence the subregion's of preventing fires independence.
