As the sewage pipe in the urban planning and construction foundation, the cement pipe can be used for sewage treatment, flood control and drainage pipes, as well as the water inlet pipes and field wells used in some unique factories and mining enterprises. When the cement pipe is delivered, the pipe socket leaks, resulting in the outflow of the covered soil layer, resulting in foundation settlement, pipeline rupture and other conditions. What is the cause of cement pipe fracture? How should we deal with it?
1、 Analysis on the causes of cement pipe fracture
(1) When arranging the concrete bearing butt joint, the mortar at the socket is not round. The mortar mix proportion of cement mortar does not meet the requirements, and the compressive strength is insufficient, but the service time has exceeded 45min.
(2) The pipe socket is not sufficiently wet for maintenance. The quality of concrete pipe fittings is poor.
(3) Because the management method of the construction enterprise is not tight, and the inspection of the project supervisor is not tight, all or some of the spare pipes are not plugged.
2、 Preventive measures to prevent cement pipeline from cracking
(1) All pipe fittings must be strictly tested. Especially after unloading, it is necessary to check whether there is any damage, gap or defect in the branch pipe. If the problem is found, it should be removed.
(2) Where rigid sockets are selected, the branch pipes shall be cleaned with cold water and kept moist. Those with rough holes shall be chiseled clean, and the mortar mix ratio of common cement mortar or pea gravel concrete shall meet the requirements of the design scheme.
(3) In case of cracks, peeling, falling and other conditions, the construction shall be strictly followed again after chiseling.
(4) Quality inspection personnel and project acceptance personnel shall pay attention to inspection and fill in system loopholes.
