Tangshan Fengrun Tianlian Cement Products Factory reminds you of the construction precautions for tunnel body cement pipes:
(1) Water is introduced into the middle concrete pipe through horizontal supply pipes. The installation of the concrete pipes is done prior to the backfilling construction of the arch. During installation, a layer of mortar is first applied at the arch's center position to serve as the foundation for the pipe sections. The overlap length of the pipe sections is 20 cm.
(2) Horizontal drain pipes are installed every 10 meters, so attention should be paid to pre-reserving the connection holes for the horizontal drain pipes and the concrete pipes during the prefabrication of the concrete pipe sections. Concrete pipes are prefabricated at the prefabrication site, with each section being prefabricated in 2-meter lengths, using standardized molds for the prefabrication templates.
Ensure that there is no blockage during the construction of cement pipes, and guarantee the smooth drainage of the blind ditches.
