The utility model belongs to the field of municipal
pipe gallery construction, and particularly relates to a UHPC board form-removal-free cast-in-place concrete municipal
pipe gallery
system which comprises an outer mold and an inner mold, a steel reinforcement framework is arranged between the outer mold and the inner mold, the outer mold and the inner mold are made of ultra-
high performance concrete in a prefabricated mode, and the outer surface of the inner mold is coated with a waterproof
coating layer. A back
shore is arranged on the top face of the inner mold, a hole is formed in the bottom face of the inner mold, a nut is downwards fixed through the hole, and the nut is downwards in threaded connection with a
set screw. By introducing the outer formwork and the inner formwork which are free of formwork removal, the advantages of factory
prefabrication and cast-in-place are combined, the on-site wet construction amount and the formwork
removal procedure are reduced, the construction period is remarkably shortened, compared with an existing prefabricated
assembly structure, splicing seams are reduced, and the leakage problem is reduced through cooperation with a waterproof
coating layer which is integrally prefabricated and painted.
