Principle of intercepting tank method: in the sewage drainage system, the intercepting tank is used to block the substances that are easy to deposit in the sewage, so as to prevent pipe blockage caused by the reduction of pipe slope and flow rate, so as to reduce the value of smaller planned flow rate and smaller planned slope of the cement pipe as appropriate, so as to reduce the buried depth of the cement pipe. During detailed planning, ordinary septic tank can be used as interception tank. Since the intercepting tank mainly blocks the easy sediment in the sewage and does not need anaerobic fermentation to purify the sewage, the volume of the sewage part can be taken as 1/3 of the normal septic tank, while the volume of the whole intercepting tank is about 1/2 of the normal septic tank.

When it comes to cement pipes, I believe you are no stranger. All kinds of cement pipes are widely used in daily life. However, although the cement pipe is very convenient to use, it also has a certain service life. 1. It is important to choose the type of cement. Only by selecting the type of cement that meets the requirements can the service life be increased. Therefore, the selection of raw material cement is also very critical. The selected cement type must meet the requirements in strength and fineness. Ordinary Portland cement is the best choice, and the setting time should not be too long. 2. Control the water cement ratio and cement consumption.

Reinforced concrete cement pipes are very common in our daily life. The common places are urban underground sewage pipes and farmland irrigation pipes, which have gradually become indispensable products for urban development. However, the price of reinforced concrete cement pipes is not always the same. Many factors have a certain impact on the price of cement pipes, so why does the price fluctuate, What are the specific factors? Next, the manufacturer of Pinghu Huafeng cement pipe will explain the factors that affect the price fluctuation of reinforced concrete cement pipe.

In the existing market, cast-in-place pipe sinking piles, precast concrete piles, bored cast-in-place piles and prestressed concrete pipe piles are widely used. Among the above pile types, prestressed concrete pipe piles are widely used due to the advantages of factory prefabrication, high concrete strength, convenient construction, and fast cycle, while cast-in-place pipe sinking piles are difficult to ensure their quality due to the need for on-site production, Due to serious environmental pollution, it is not suitable for geological conditions with thick soft soil layer, which is prone to necking, and the construction period is very long, so it has gradually been eliminated by the market. For example, the Guangdong Provincial Construction Commission has clearly stipulated that the use of immersed cast-in-place piles is not allowed, and the Zhejiang Provincial Department of Construction has also restricted the use of immersed cast-in-place piles.

1. Centerline setting of pipeline: before construction, the starting point, end point, plane break point, longitudinal break point and straight line control center pile of the centerline can be measured on the site according to the center line control point given in the design, and the direction control pile can be set at the appropriate position outside the groove of the starting point and end plane break point, and the pile number can be determined through measurement. 2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly conducted by excavator, supplemented by manual bottom cleaning, and the connection pipe and branch pipe of rainwater hopper are excavated manually. During excavation, pay attention to the change of soil quality, and support the sections with signs of collapse.
