Description
Technical Field
The utility model belongs to the drainage pipe field, concretely relates to distribution of rain and sewage pipeline.
Background
To the great enterprise in outdoor operation place, for reducing sewage treatment pressure, all can carry out the distribution of rain and sewage, be about to the rainwater arrange to urban rainwater pipeline in, separately collect with enterprise sewage to reduce sewage treatment capacity.
In general, in the early stage of rainfall, rainwater washes the ground to wash away pollutants on the ground, so that the rainwater in the early stage carries a large amount of pollutants and needs to be collected into a sewage tank for treatment; after the rain falls for a period of time, the rain reaches the urban discharge standard and can be directly discharged into a rain pool or an urban rainwater pipeline.
However, in the existing rain and sewage diversion pipeline, only two branch pipes leading to a sewage pool and a rainwater pool are provided with intercepting valves, and after rainfall, the sewage intercepting valve is opened and the rainwater intercepting valve is closed, so that initial rainwater flows to the sewage pool; after the rain falls for a period of time, the sewage interception valve is closed, and the rainwater interception valve is opened, so that the rainwater flows to the rainwater tank. However, the rainwater carries impurities such as gravel and the like, and when the impurities enter the rainwater basin along with the rainwater, firstly, the valve is scaled, and the service life of the valve is influenced; secondly, sundries such as gravel and stones are accumulated at the valve, so that the sealing effect of the valve is influenced; thirdly, in some metallurgical enterprises' rain sewage reposition of redundant personnel pipelines, probably contain heavy metal in the gravel that the rainwater carried, can pollute the rainwater in the rainwater pond and even pollute city rainwater pipeline. There is therefore a need for a method or apparatus to address these problems that ensures reliable distribution of rain and sewage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a distribution of rain and sewage pipeline can avoid the debris that carries in the rainwater to influence the life and the leakproofness of valve.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a distribution of rain and sewage pipeline, includes the trunk line with the switch-on of dirty collection system outlet of rain, trunk line low reaches includes two branch pipes of sewer pipe and downspout, two branch pipes access to sewage pond and rainwater pond respectively, and are equipped with respectively on two branch pipes and hold back the valve, the upstream intracavity that the valve was held back to the rainwater was gone up to the rainwater pipe is provided with the baffle, the vertical setting of baffle is at one section of downspout and is put the pipe intracavity, and the baffle links firmly with downspout lower part pipe wall, gapped with downspout upper portion pipe.
By adopting the scheme, the sewage interception valve is opened and the rainwater interception valve is closed during rainfall, so that initial rainwater is discharged to the sewage tank; after rainfall for a period of time, the sewage interception valve is closed, the rainwater interception valve is opened, rainwater flows to the rainwater pool, impurities carried in the rainwater move along with the water flow at the lower part of the pipe cavity, the impurities can be intercepted by the baffle, and the rainwater on the upper part of the pipe cavity flows through the baffle from the baffle to enter the rainwater pool. Therefore, the utility model discloses a debris that the scheme carried in can avoiding the rainwater get into the rainwater pond, have also avoided going out the scale deposit at the rainwater trapping valve, influence the life or the leakproofness of rainwater trapping valve.

In the figure: 10-sewer, 11-sewage trap, 20-sewer, 21-rainwater trap, 30-flap, 40-sewer flap, 50-trash hole or trash connector, a-rainwater collection system, B-sewage tank, C-rainwater tank
Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings.
The utility model provides a distribution of rain and sewage pipeline, includes the trunk line of putting through with rain and sewage collection system A outlet, the low reaches include two branch pipes of sewer 10 and sewer 20, two branch pipes 10, 20 lead to respectively in effluent water sump B and rainwater pond C, and are equipped with the valve that intercepts, its characterized in that on two branch pipes 10, 20 respectively: a baffle 30 is arranged in an upstream pipe cavity of the rainwater interception valve 21 on the rainwater pipe 20, the baffle 30 is vertically arranged in a section of horizontally arranged pipe cavity of the rainwater pipe 20, and the edge of the baffle 30 is fixedly connected with the lower pipe wall of the rainwater pipe 20 and has a gap with the upper pipe wall of the rainwater pipe 20.
Preferably, the connection position of the baffle 30 and the inner pipe wall of the rain pipe 20 is welded. Other reliable connection modes can be arranged to bear the long-time impact of water flow.
After the pipeline is used for a certain time, cleaning operation is needed, namely sundries intercepted by the baffle are cleaned out, so that the effect of the baffle is prevented from being influenced by the excessive sundries. The rainwater pipe 20 where the baffle 30 is located is provided with a impurity removing hole or an impurity removing joint 50. Namely, a through hole with a plug is arranged on the upstream pipe wall close to the baffle 30, and sundries can be cleaned out from the through hole after the hole plug is taken off during cleaning; the pipeline can be connected by flanges, and the flange connection is directly opened for cleaning when sundries are cleaned.
Such a baffle may also be designed in the sewer pipe 10 to extend the service life of the trap. Namely: a sewage pipe baffle 40 is arranged at the upstream of the sewage interception valve 11 on the sewage pipe 10, the sewage pipe baffle 40 is vertically arranged in a section of horizontally-arranged pipe cavity of the sewage pipe 40, the edge of the sewage pipe baffle 40 is fixedly connected with the lower pipe wall of the sewage pipe 10, and a gap is reserved between the edge of the sewage pipe baffle 40 and the upper pipe wall of the sewage pipe 10; the sewage pipe 10 where the sewage pipe baffle 40 is located is provided with a impurity cleaning hole or an impurity cleaning joint 50.
