Embodiment Construction

[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , figure 2 As shown, when the rain and sewage pipes (canals) 1 enter the corridor and are located below the integrated pipe corridor 4, the drainage inspection well 2 of the present invention is arranged on one side of the pipe corridor, and the lower part of the drainage inspection well 2 extends to the lower part of the pipe corridor. The flow-through part below the drainage inspection well 2 is connected to the upstream and downstream rainwater and sewage pipes (canals) 1 in a straight line, but the level of the inlet and outlet of the drainage inspection well 2 deviates from the rainwater and sewage pipes (canals) 1. 1. On one side of the side wall of the sewage pipe (canal) 1, the inlet and outlet of the drainage inspection well 2 and the overflow part are connected at the bottom of the drainage inspection well...

Abstract

The invention discloses an arrangement method for drainage inspection wells applied to a comprehensive pipe rack. The lower portion of the comprehensive pipe rack is provided with a rain and sewage channel. The arrangement method is characterized by comprising the following steps that the drainage inspection wells leading to the ground are arranged along the comprehensive pipe rack at equal intervals and are arranged on one side of the comprehensive pipe rack; the lower portion of each drainage inspection well is provided with a flow passing part which stretches into the lower portion of the comprehensive pipe rack; the flow passing parts of the drainage inspection wells and the upstream and downstream rain and sewage channel are located on the same straight line; inlet and outlet openings of the inspection wells are horizontally moved to one side of the pipe rack; and the inlet and outlet openings of the inspection wells upwards lead to the ground. The arrangement method has the following beneficial effects that the arrangement of pipelines above cannot be affected by the inspection wells, and the arrangement of pipelines above is simple and smooth; the arrangement of the pipelines above cannot be affected by the inspection wells, and the pipelines above the same side can be gravity pipe channels; and the flow passing parts of the inspection wells are smoothly jointed with the upstream and downstream rain and sewage pipe (channel), so that blockage is not likely to happen.

Description

technical field [0001] The present invention relates to a setting method of a drainage inspection well applied to a comprehensive utility gallery, in particular to an inspection well used for rain and sewage pipes (canals) under an urban comprehensive utility gallery without affecting the layout of pipelines above the comprehensive utility gallery craft. Background technique [0002] The "Technical Specifications for Urban Comprehensive Pipe Gallery Engineering" (GB50838) clarifies that urban engineering pipelines such as rainwater can be included in the comprehensive pipe gallery, and the sewage pipe entry gallery should be located under other pipelines. However, there are some difficulties when the rain and sewage inlet corridors are arranged under the pipe corridors: rain and sewage pipes (canals) need to be equipped with inspection wells at certain distances for access to rainwater or sewage, and for clearing and maintenance. In order to facilitate maintenance, the insp...
