Abstract

The utility model discloses a cross structure of pipes in the water supply and drainage systems. Other pipe (2) passes directly through an inspection well (1), the gravity pipes in the inspection well include a inflowing gravity pipeline (3) and an outgoing gravity pipe (4), which are opposite to each other in the inspection well, the inflowing gravity pipe (3) is higher than or equal to the outgoing gravity pipe (4), a water chute (5) is arranged at the bottom of the inspection well (1), the bottom of the water chute (5) connects the lower part of the inflowing gravity pipe (3) to the lower part of the outgoing gravity pipe (4). The utility model solves the problem that for the pipes in the drainage pipe system the water in the gravity pipe cannot flow into the discharge point of preset elevation normally due to the elevation of the gravity pipe decreases considerably.

Description

Pipeline chi structure in a kind of water supply and sewerage pipeline

Technical field

The utility model relates to the pipeline chi structure in a kind of water supply and sewerage pipeline.

Background technology

When laying water supply and sewerage pipeline, the various pipelines that run into more than two or two through regular meeting differ the place intersection of very little (being less than or equal to 100mm) in the same depth or the degree of depth, but do not need to connect, and so just must get out of the way mutually.The mode of generally dodging is to utilize pipe fitting that the absolute altitude of pressure conduit is reduced, and walks around pipe gravity flow pipeline or other pipeline, according to code requirement, the pipeline of caliber 〉=300mm, when both intersected, the spacing between two pipelines must be greater than 500mm, the actual very difficulty that implements.It is very dark that the pipeline that descends may fall, and can influence the construction costs of whole water supply and sewerage pipeline like this.If particularly the pipeline of two intersections all is the pipe gravity flow pipeline that does not have pressure, if reduced absolute altitude, water just can not normally flow into the drainage point of predetermined absolute altitude.Therefore the intersection that needs the to solve pipeline problem of colliding makes the absolute altitude of pipe gravity flow pipeline reduce less as far as possible, or does not reduce, and makes sewage can normally be discharged into the drainage point of being scheduled to absolute altitude.

Summary of the invention

The purpose of this utility model is: the chi structure of the pipeline in a kind of water supply and sewerage pipeline is provided, solve when pipeline intersects in the water supply and sewerage pipeline, because free-draining pipeline absolute altitude reduces too many, the problem that makes the ducted water of free-draining can not normal drainage go into to be scheduled to the absolute altitude drainage point.

The utility model is to constitute like this: it comprises manhole 1, in manhole 1, there is other pipeline 2 directly from manhole 1, to pass, pipe gravity flow pipeline in the manhole comprises inflow direction pipe gravity flow pipeline 3 and water outlet direction pipe gravity flow pipeline 4, inflow direction pipe gravity flow pipeline 3 and water outlet direction pipe gravity flow pipeline 4 are located in the manhole two sides vertical with other pipeline 2 respectively, inflow direction pipe gravity flow pipeline 3 is greater than or equal to water outlet direction pipe gravity flow pipeline 4, be provided with slide tank 5 in the bottom of manhole 1, the bottom of slide tank 5 is connected the bottom of inflow direction pipe gravity flow pipeline 3 with the bottom of water outlet direction pipe gravity flow pipeline 4.

Owing to adopted technique scheme, the pipe gravity flow pipeline that the utility model should intersect with other pipeline 2, blocking in manhole is two sections, one section is inflow direction pipe gravity flow pipeline 3, another section is a water outlet direction pipe gravity flow pipeline 4, and its two sections mouths of pipe after blocking are concordant with the sidewall of manhole.Therefore, compared with prior art, when the utility model has solved pipeline in the water supply and sewerage pipeline and has intersected because free-draining pipeline absolute altitude reduces too many, the ducted water of free-draining can not normally flow into the problem of predetermined absolute altitude drainage point, and the height that the utility model can make the free-draining pipeline reduce reduces greatly even can not reduce height.
