Description
Technical Field
The invention relates to a drainage well, in particular to a drainage well for rain and sewage, and belongs to the technical field of urban underground drainage.
Background
Along with the continuous development of urbanization, the scale of cities becomes larger gradually, the population of living is increased year by year, the original infrastructure construction of cities can not meet the normal living demands of urban residents, wherein in recent years, the urban drainage is difficult, the waterlogging phenomenon is particularly serious, and the benign development of cities is influenced, so that the urban drainage system is urgently required to be subjected to rain and sewage separation and reconstruction. In the past, because the urban infrastructure construction is relatively lagged behind, drainage pipelines are not separately arranged according to water sources, and a form that rainwater and sewage share one drainage pipeline, namely a combined drainage system, is adopted. If the fully prefabricated rainwater and sewage combined sewer well adopting the design is adopted in urban rainwater and sewage diversion engineering, not only can the original pipeline be utilized, but also the excavation amount of the engineering can be reduced. The design can also improve urban waterlogging phenomenon of cities due to rainstorm, and rainwater which is not discharged in time can be discharged by the sewage pipe through the sewage draining well during rainstorm.
Underground cable is a cable which is buried underground compared with common overhead lines, and is also called underground cable. Cables are made of one or more mutually insulated conductors surrounded by an insulating layer and a protective layer for transmitting power or information from one location to another. After entering modern society, due to the reasons of shortage of urban land, high traffic pressure, urban construction and the like, underground cable power transmission is commonly adopted in large cities. Compared with an overhead line, the cable has the advantages of small occupied area, reliable power transmission, strong anti-interference capability and the like.
Disclosure of Invention
In order to solve the defects of the prior art, the invention aims to provide the rainwater and sewage sharing sewer well which is compatible with rainwater and sewage distribution and can effectively solve the problem of difficult drainage of the existing city.
In order to achieve the above object, the present invention adopts the following technical solutions:
a rainwater and sewage combined sewer well has a well cavity divided into a rainwater cavity and a sewage cavity by a partition wall;
the bottom sides of the rainwater cavity and the sewage cavity are respectively provided with a preformed hole for connecting a rainwater pipe and a sewage pipe;
the upper end of the partition wall is provided with an overflow hole,
and a one-way valve which flows from the rainwater cavity to the sewage cavity is arranged in the overflow hole.
The top in above-mentioned rainwater chamber and sewage chamber is equipped with the well lid mounting groove respectively.
Further, the well lid mounting groove at the top in above-mentioned rainwater chamber and sewage chamber, an organic whole sets up.
The side wall of the rainwater cavity and/or the sewage cavity is provided with a group of cable holes.
And a cable platform corresponding to the cable hole is arranged in the rainwater cavity and/or the sewage cavity.
The rainwater and sewage combined sewer well is of an integrated prefabricated structure.
The invention has the advantages that:
the invention discloses a rainwater and sewage combined sewer well, which has the following advantages:
(1) the rainwater pipe and the sewage pipe are integrated, so that the rainwater pipe and the sewage pipe can be buried according to the original ditch line, and the project amount of rainwater and sewage distribution is reduced;
(2) the overflow hole is arranged on the partition wall and the one-way valve is arranged, when a city rainstorm occurs, the flow rate of rainwater in the city which is gathered into the rainwater cavity is larger than the flow rate discharged by the rainwater pipe, and the water level of the rainwater cavity rises to the state that the overflow hole flows into the sewage well through the one-way valve and flows out through the sewage well; not only urban inland inundation can be avoided, but also the sewage pipe can be flushed to prevent the sewage pipe from being blocked;
(3) low voltage cables can also be laid from there without the need to dig channels to bury the cables.
The rainwater and sewage combined sewer well has the advantages of simple structure, capability of being prefabricated in a large quantity, capability of being integrally buried when the sewer well is applied, three-in-one arrangement of the rainwater cavity, the sewage cavity and the cable laying, capability of reducing the engineering quantity and accelerating the construction progress, small influence on city reconstruction, capability of effectively solving the problems of difficult drainage and the like of the existing city while being compatible with rainwater and sewage distribution, and strong practicability and wide applicability.

FIG. 1 is a schematic view of a rainwater and sewage drainage well according to the present invention.
The designations in the drawings have the following meanings: 1. rainwater chamber, 2, sewage chamber, 3, downspout preformed hole, 4, sewer preformed hole, 5, cable hole, 6, cable platform, 7, overflow hole, 8, check valve.
Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
According to the rainwater and sewage combined drainage well, the well cavity is divided into a rainwater cavity and a sewage cavity by the partition wall; the upper end of partition wall is equipped with the overflow hole, and, is equipped with the check valve from rainwater chamber flow direction sewage chamber in the overflow hole.
A group of rainwater pipe preformed holes are formed in the bottom side of the rainwater cavity and used for connecting rainwater pipes;
the bottom side of the sewage cavity is provided with a group of sewage pipe preformed holes for connecting a sewage pipe.
As shown in fig. 1, a set of cable holes is formed in the sidewall of the upper end of the sewage chamber for cable to run, and a cable table is formed in the sewage chamber for holding the cable tube, preventing the cable tube from sagging for a long time, and isolating sewage.
The top in rainwater chamber and sewage chamber is equipped with the well lid mounting groove respectively, and is further, and two well lid mounting grooves also can be connected as an organic whole.
In the rain and sewage diversion project, the whole body can be prefabricated firstly and is placed at the installation position. The two rainwater pipe preformed holes are connected with a rainwater pipe in an underground drainage system; the two sewage pipe preformed holes are connected with a sewage pipe in an underground drainage system; the cable hole is connected with the cable pipe, the cable is laid through manual laying and mechanical traction laying, and if the cable does not need to be passed through, the cable preformed hole can be temporarily blocked and opened when needed.
Rainwater on the urban street is converged into the rainwater cavity and then is discharged to a sewage treatment plant through a rainwater pipe; the domestic sewage in the city is discharged into the sewage cavity through a water pipe in the house and then is discharged into a sewage treatment plant through a sewage pipe. At ordinary times, the sewage in the sewage cavity is less, and when rainstorm occurs, if the drainage flow of the rainwater pipe is insufficient, the water level in the rainwater cavity rises to the position of the overflow hole, and then the sewage cavity can be discharged through the check valve and is discharged through the sewage pipe. The one-way valve can effectively prevent sewage in the sewage cavity from entering the rainwater cavity, and the rainwater can play a role in flushing the sewage cavity and the sewage pipe, so that the one-way valve has an important role in preventing the plugging of the sewage pipe.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
