生产厂家浅谈混凝土水泥管使用方法。 Guangzhou cement pipe manufacturer talks about the use of concrete cement pipe. Cement pipe Wang Wenshengyi is a pipe made of cement. It is widely used in our lives, and has a wide range of uses. It is powerful and the market is gradually expanding. Concrete cement pipe is a type of cement pipe. The Guangzhou cement pipe manufacturer will talk about it below. How to use concrete cement pipes.
1. Set up a retention pond method
Principle: In this method, a retention pond is used in the sewage discharge system to block the simple sedimentary substances in the sewage to prevent pipeline blockage caused by the decrease of the slope of the pipeline and the decrease of the flow rate. In order to reduce the buried depth of the cement pipeline, the value of degree should be used. In specific planning, a general septic tank can be used as a retention pond. Because the trapping pond mainly blocks the easy sediment in the sewage and does not require anaerobic fermentation to purify the sewage, the volume of the sewage part can be 1/3 of the normal septic tank when the capacity is calculated, and the volume of the entire trapping tank is about normalized Septic tank. When planning a cement pipeline, the slope of the pipeline in front of the retention pond cannot be reduced. For cement pipelines treated with anti-fouling treatment in the retention pond, the values of small planned flow rate and small planned slope can be reduced by a hundred percent compared to the minimum value specified in the specification. Points. The method is suitable for a residential area or a factory area where the terrain is flat and the starting point (control point) of the pipeline is far from the access point of the municipal cement pipe network.

2. Overflow well discharge method

Principle: The sewage is discharged into the municipal cement pipe through the overflow well first, and the pump is used as an auxiliary to remove the accumulated water in the overflow well and the upstream cement pipeline. The flow rate should be determined according to all the accumulated water discharged inside. In order to reduce operating costs, a sewage booster pump can be started before daily peak water usage to drain the water in overflow wells and upstream pipelines. In this way, the sewage can be prevented from staying in the pipeline for a long time and siltation can be formed, and the water accumulation pipe section is often washed away, which is beneficial to the ventilation of the pipeline and the elimination of harmful gases in the pipeline. When planning a cement pipeline system, the slope of the cement pipeline above the overflow water level should be minimized to reduce the length of the water accumulation pipe section and the amount of water in the drainage system, and the slope of the cement pipeline below the overflow water level should not be too large. Small, it should be ensured that the water flow has a certain scouring strength to the pipeline when the pipeline is pumping. This method is suitable for the control points of cement pipelines that are close to the access points of the municipal cement pipeline network.The selected method still does not allow the residential cement pipelines to connect to the municipal pipeline network, and small-scale residential districts or plant areas are also suitable for rainwater. Emission system. When used in rainwater drainage systems, rainwater is discharged through overflow wells, and the rainwater raising pump is turned on only after each rain and when the pipeline needs to be dredged and protected to remove the accumulated water in the pipeline.

3. Pipeline penetration method
Principle: When the cement pipeline is buried when it encounters the current pipeline or the rain cement pipeline is interspersed, the pipeline penetration method is used, which can reduce the buried depth of the pipeline and is not easy to block. Set up an inspection well at the pipeline crossing to allow another pipeline to pass through the well.The key is to ensure that the water passing area in the well (the area shaded in the figure) is greater than or equal to the cross-sectional area of the pipe being penetrated and the size of the water passing area in the well It can be controlled by the size of the through-hole inspection well. The principle of pipe running is that small pipes run through large pipes, and current pipes run through planned pipes.
The above three methods of reducing the buried depth of cement pipelines can use existing conditions to deal with the problem of insufficient buried depth of municipal cement pipeline networks on the basis of not violating the regulations, and have obtained certain economic benefits, and have been checked by actual engineering.
Guangzhou cement pipe manufacturers have specialized in making cement pipe products for many years. Good after-sales service reputation has spread throughout the country, and the service is thoughtful and caring. It is the first choice brand for domestic cement pipes. Buying Guangzhou cement pipes is just buying with confidence. This concludes the introduction of concrete cement pipes.
