How much is the Zhangjiakou cement tank

Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Cement pipes have the following characteristics: 1. Generally speaking, they have rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe. 3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years.

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.

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.

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 carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.
