Standard requirements and precautions when installing cement pipes in installations
Cement drainage pipes are often used in municipal engineering in our cities. It is often used as drainage pipes for rainwater and domestic sewage in cities. Cement pipes have been used in various industries because of their unique characteristics. Need to pay attention to safety, need to install the device according to the construction steps, pay attention to the construction requirements, and avoid unnecessary work. When installing the cement pipe, we must carefully construct according to the specific process and plan. The Henan cement pipe manufacturers will guide you to understand the standard requirements of cement pipes in the construction of the equipment. What problems should be paid attention to when the cement pipes are installed?
Standard requirements and precautions for cement pipes during device construction
I. Standard requirements for cement pipes during device construction
1. Set the centerline of the pipeline: Before construction, the starting point, end, plane vertices, vertical vertices, and straight line control center piles of the centerline can be measured at the site according to the given centerline control points. The appropriate position outside the groove is set to control the pile, and the pile number is confirmed by measurement.
2. Establish a temporary level point: Pipeline projects often need to add a temporary level point, which should be set at a place that is stable and difficult to be bumped, and its spacing is not more than 30 meters. Temporary level closure should meet the required standards.
3. The trench excavation is mainly excavated by excavators, supplemented by manual bottom cleaning, and the rainwater bucket connecting pipes and branch pipes are excavated manually. During the excavation process, pay attention to observe the changes in soil quality, and support and protect the road sections with landslide marks.
4. The excavator digs to the bottom of the tank at a height of about 10cm. The soil at the bottom of the tank is not to be dug, and it will be manually removed to repair the bottom of the tank. Manually clean the trough, carefully check the soil at the bottom of the trough for any disturbance, and if there is disturbance, special treatment should be done.
