Prefabricated type reinforced concrete underground comprehensive pipe gallery and production mold thereof

Abstract

The invention mainly discloses a prefabricated type reinforced concrete underground comprehensive pipe gallery. The prefabricated type reinforced concrete underground comprehensive pipe gallery is formed by sequentially arranging a plurality of integral type unit joints. The integral type unit joints comprise trough type prefabricated reinforced concrete plates and / or I-shaped, L-shaped and T-shaped prefabricated reinforced concrete plates and prefabricated reinforced concrete flat plates. All the plates are solid prefabricated plates, and upward-stretching connecting reinforcements are arranged on the top faces of the plates. The two trough type prefabricated reinforced concrete plates of each integral type unit joint are symmetrically spliced, or the trough type prefabricated reinforced concrete plates are combined with other prefabricated reinforced concrete plates or combined in a matched manner to form an integral type unit joint framework with a single channel or a left-and-right channel or an upper-and-lower channel or four upper-and-lower channels. Reinforced concrete overlapping layers are poured on the top face and the bottom face of the framework respectively to form the corresponding integral type unit joints. All the plates are prefabricated, then transported to the site and spliced according to process requirements, then reinforced concrete overlapping layers are poured, and therefore the integral type unit joints are manufactured and mounted. The manufacturing cost can be greatly lowered through workshop batch prefabrication, and the site construction period is greatly shortened through the treatment process of pouring the integral overlapping layers after site framework assembling and cooperation.

Description

technical field [0001] The invention relates to a reinforced concrete underground comprehensive pipe gallery, in particular to a prefabricated assembled reinforced concrete underground comprehensive pipe gallery and a production mold thereof. Background technique [0002] With the development of urban construction, the construction of underground comprehensive pipe gallery is about to enter the climax of large-scale construction. At present, the design of the underground comprehensive pipe gallery generally adopts the reinforced concrete cast-in-place structure, and only a small part of the small diameter adopts the structural form of prefabrication and then assembly. The connection between each section forms a rigid whole through the pre-embedded steel structural parts and the concrete cast-in-place belts at the corresponding steel structural parts. The advantages of the cast-in-place reinforced concrete integrated pipe gallery structure are structural safety, good waterpr...
