The utility model discloses drawing forth branch mouth under the pipeline that will dodge the barrier, need not to reduce the piping lane elevation because of dodging the pipeline, need not to increase and fall the rainbow section and link up the elevation change, only need carry out local treatment to pipeline branch mouth, move towards complete nothing to the whole elevation of piping lane, can realize branch mouth function and save engineering cost again, be one kind and dodge the reasonable pipeline of barrier and draw forth the form down.

Description

Lower leading-out pipeline branch port for avoiding obstacles

Technical Field

The utility model relates to a technical field of utility tunnel node design, it improves on for the basis of drawing forth mouthful at conventional pipeline to the realization can dodge the piping lane obstacle pipeline along the line, satisfies the design of pipeline business turn over piping lane function simultaneously, specifically is a lower drawing forth pipeline branch mouth of dodging the barrier.

Background

The comprehensive pipe gallery engineering is that a municipal shared tunnel is built under urban roads, various municipal pipelines such as electric power, communication, water supply, reclaimed water, cold and hot water pipes, fuel gas and the like are integrated, and unified planning, unified construction and unified management are carried out, so that comprehensive utilization of underground space and resource sharing are achieved, and the intensive management target of the pipelines is achieved.

The pipeline branch port has undertaken the basic function that all kinds of pipelines outside the pipe gallery get into business turn over pipe gallery. The outside business turn over pipeline of piping lane is generally crossed with the piping lane plane, and the piping lane roof is raised to business turn over piping lane, generally adopts the part, and the mode that supplies the pipeline discrepancy realizes branch mouthful basic function. If there is barrier pipeline in the elevation scope of drawing forth on the piping lane along the line, then can't realize and draw forth the function.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lower outlet line branch mouth of dodging barrier through the local processing of line branch mouth, need not adjustment piping lane elevation, easily solves because of barrier thing piping line elevation problem, can't utilize the pipeline business turn over problem that the space realized leading out above the piping lane roof, and simple structure is reasonable, practices thrift the cost.

In order to realize the purpose, the technical scheme of the utility model is that:

the utility model provides a dodge lower outlet pipe line branch mouth of barrier, its characterized in that pipeline cabin discrepancy pipeline position bottom plate is local deep, and the local increase of pipeline cabin discrepancy pipeline position piping lane clear width forms a pipeline poling layer, and the pre-buried sleeve pipe of pipeline poling layer wallboard to make the pipeline pass in and out the piping lane from the space below the bottom plate.

The pre-buried waterproof sleeve pipe of pipeline poling layer business turn over pipeline department wallboard and the special waterproof assembly of cable communication cable, the pipe gallery outside line adopts the concrete package calandria.

Pipeline cabin discrepancy pipeline position bottom plate local position depths set up glass steel guidance tape and cat ladder to satisfy the normal basic function of laying of corridor interior pipeline and normally overhauing in the personnel's piping lane.

The local depths that fall of business turn over pipeline set up sump pit and drain pump, utilize drain line to insert the outside drainage collecting system of piping lane.

The regional space can't utilize above the piping lane roof, and still will satisfy under the condition of the function of being connected of lateral line and main line, the utility model discloses space below the make full use of piping lane bottom plate, the local bottom plate of drawing forth the pipeline cabin that falls deeply, lateral line utilize this space business turn over piping lane. The utility model discloses drawing forth branch mouth under the pipeline that will dodge the barrier, need not to reduce the piping lane elevation because of dodging the pipeline, need not to increase and fall the rainbow section and link up the elevation change, only need carry out local treatment to pipeline branch mouth, move towards complete nothing to the whole elevation of piping lane, can realize branch mouth function and save engineering cost again, be one kind and dodge the reasonable pipeline of barrier and draw forth the form down.

Detailed Description

The invention is further described with reference to the following figures and examples.

The utility model discloses mainly include:

the utility model provides a dodge lower outlet pipe line branch mouth of barrier, has the condition of barrier on the pipeline above pipe gallery standard section roof in the space of drawing forth, is adjusted the pipeline discrepancy pipe gallery form into from the space below the bottom plate and gets into business turn over pipe gallery.

For realizing the function that the pipeline gets into the pipe gallery from the space below the pipe gallery bottom plate elevation, pipeline cabin bottom plate department should local fall deeply 1, and the depth of fall should be confirmed according to pipeline kind and size to guarantee pipeline business turn over function.

For reducing the pipeline and being connected required extra space with the person in charge when drawing forth, do not influence the operation function of main pipeline in the piping lane, guarantee simultaneously that the staff has sufficient maintenance operating space, the clean width of extraction position piping lane should local expansion. The width increment value is determined by the pipeline type and size.

For satisfying the local depths that fall of piping lane cabin bottom plate, the staff sets up glass steel walkway plate 3 and overhauls cat ladder 4 along the current continuity of access way 8 maintenance in the piping lane and the function that gets into the maintenance that the deep position goes on, sets up current requirement at the local depths that fall of bottom plate, and glass steel walkway plate 3 satisfies current requirement, and the space supplies business turn over pipeline conversion to utilize outside the walkway plate.

Original cabin remains the former state, and original cabin bottom plate is local to fall deeply, forms a pipeline poling layer, and the pre-buried waterproof sleeve pipe of poling layer wallboard does not establish the baffle between pipeline poling layer and the original cabin, and the pipeline bends from this layer and can get into the original cabin space scope of piping lane, only sets up the glass steel pavement board at piping lane pedestrian passageway department and supplies the people to pass.

Business turn over pipeline department wallboard is as good as with ordinary pipeline branch mouth wallboard, adopts pre-buried waterproof jacket 2 and the special waterproof assembly of cable communication cable, and the pipe gallery outer pipeline adopts concrete package calandria 6, realizes the function of cominging in and going out according to actual elevation demand.

For solving the local deep drainage problem that falls, should set up sump pit 5 and drain pump according to drainage professional requirement, set up the outside drainage collection system of drain line access piping lane.

In the past, when the pipeline can not be led out at the branch port of the upper leading-out pipeline, a processing method of reducing the overall height of the branch port of the pipeline corridor is adopted for avoiding the pipeline, and meanwhile, for the change of the height of the connection pipeline corridor, inverted siphon sections are required to be arranged at the two ends of the branch port, the larger the local reduction height difference of the branch port is, the longer the inverted siphon section length is, and the longer the buried depth increasing section is, so that the engineering cost is directly increased. And the branch port is led out from the lower part of the pipeline avoiding the obstacle, only the local treatment is needed to be carried out on the branch port of the pipeline, the whole elevation trend of the corridor is not influenced completely, and the method is a good method which can realize the function of the branch port and save the construction cost.
