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 cement pipe is very convenient to use, it also has a certain service life, so how to extend the life of cement pipe in daily production and life is a problem. Next, we will explore how to prolong the service life of cement pipe?
1. It is important to choose the cement type
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 water cement ratio and cement consumption
Main purpose of cement pipe
1. It is generally used for drainage pipes of rainwater and sewage in cities and towns.
2. It can be used as the outer sleeve for laying pipelines underground, such as tap water, electric power and telecommunications, and gas forces.
3. Vertical and horizontal drainage and seepage of expressway.
Installation and construction steps
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 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.
5. On both sides of the trench and 1m above the bottom of the trench, elevation piles shall be set symmetrically, and elevation nails of equal height shall be nailed on them. The center line of the pipe channel and the elevation of the elevation pile shall be re measured before the bottom of the trench is reached and the pouring is leveled.
6. The height of soil piling on one side of the trench shall not be more than 2 meters, and the distance from the trench edge shall not be less than 1 meter. The protection of underground pipelines for trench construction shall be disclosed to the relevant departments first to clarify the basic location of underground facilities. If necessary, sample holes shall be excavated first to find out the exact location, facilitate construction, and ensure the safety of various embedded pipelines, Support protection measures shall be taken for exposed pipelines.
Precautions during construction
1. Before putting the cement pipe into use, check whether the cement pipe is intact. If there are cracks, repair them in time. If they cannot be repaired, replace them. Do not use damaged or inferior cement pipes, which will affect the safety of the project.
2. The workers of cement pipe laying must have professional experience, the relevant departments should do a good job in supervision, and each procedure should be well controlled, otherwise the unqualified foundation in the early stage will lead to more problems in the later construction, and the problem should not be buried underground, because maintenance will consume a lot of human and financial resources.
3. When laying pipelines, the established construction scheme shall be strictly followed, and do not make decisions or cut corners, otherwise the project quality will not be guaranteed.
4. After the cement pipe is laid, the special quality inspection department shall further review it to ensure the project quality.
