Problems solved by technology
[0004] The purpose of the present invention is to provide a branch port of the lower lead-out pipeline that avoids obstacles. Through the local treatment of the branch port of the pipeline, there is no need to adjust the elevation of the pipe gallery, and it is easy to solve the problem of the elevation of the pipeline due to obstacles, which cannot be realized by using the space above the roof of the pipe gallery. The problem of the in and out of the pipeline drawn from above, the structure is simple and reasonable, and the cost is saved

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] The present invention mainly comprises:
[0018] The utility model relates to a branch port of a lower lead-out pipeline that avoids obstacles. When there is an obstacle in the lead-out space of the pipeline above the roof of the standard section of the pipe gallery, the form of the pipeline entering and exiting the pipe gallery is adjusted to enter and exit the pipe gallery from the space below the bottom plate.
[0019] In order to realize the function of pipelines entering the pipe gallery from the space below the floor level of the pipe gallery, the floor of the pipeline cabin should have a local fall depth of 1, and the depth of fall should be determined according to the type and size of the pipeline to ensure the function of pipeline entry and exit.
[0020] In order to reduce the extra space required to connect the branch pipe and the main...

The invention discloses a downward led-out pipeline branch port for avoiding obstacles. The downward led-out pipeline branch port is characterized in that a bottom plate at a pipeline entering and exiting part of a pipeline cabin is deeply embedded, the net width of a pipeline corridor at the pipeline entering and exiting part of the pipeline cabin is locally increased to form a pipeline penetrating layer, and a sleeve is embedded into a wall plate of the pipeline penetrating layer, so that the pipeline enters and exits the pipeline corridor from the space below the bottom plate. According tothe downward led-out pipeline branch port for avoiding the obstacles, the elevation of the pipeline corridor is not required to be reduced due to avoiding the pipeline, the increase of the connectingelevation of an inverted siphon section is not required, only local treatment on the pipeline branch port is needed, no influence is exerted on the overall elevation direction of the pipeline corridor, the function of the branch port is can realized, the engineering cost is reduced, and the downward led-out pipeline branch port is a reasonable pipeline downward led-out mode for avoiding the obstacles.
Description
technical field [0001] The invention relates to the technical field of node design of comprehensive pipe gallery, which is improved on the basis of conventional pipeline outlets, so as to realize the design of avoiding obstacles along the pipe gallery and satisfying the function of pipelines entering and leaving the pipe gallery, specifically a design for avoiding The branch outlet of the lower outlet pipeline of the obstacle. Background technique [0002] The comprehensive pipe corridor project refers to the construction of a municipal shared tunnel under the urban road, which gathers various municipal pipelines such as electricity, communication, water supply, reclaimed water, hot and cold water pipes, and gas, and implements "unified planning, unified construction, and unified management" ", in order to achieve the comprehensive utilization of underground space and the sharing of resources, and at the same time achieve the goal of intensive management of pipelines.
