Description
Technical field
The present invention relates to a kind of assembled pipe gallery, specifically a kind of jigsaw assembled pipe gallery and construction method.
Background technique
With greatly developing for pipe gallery construction, the construction of pipe gallery is also increasing, currently used integrated pipe
Corridor is cast-in-place concrete piping lane, and this all wet constructions of piping lane, live formwork, cast in situs, construction precision is low, construction period
It is long, it causes serious pollution to the environment, is unfavorable for industrialization, industrialization production, is disagreed with the developing direction of building industry, in view of current
Pipe gallery status is badly in need of a kind of production technology that can be consistent with architectural industrialization developing direction.
In addition traditional cast-in-place concrete piping lane, needs a large amount of construction worker, and recruitment difficulty is increasingly prominent at present, cast-in-place
Construction can be increasingly difficult to, jigsaw assembled pipe gallery, and prefabricated ratio is high, component whole industrialized production, reduce manually at
This, adapts to the direction of architectural industrialization development.
The patent of Publication No. CN108797637 A discloses a kind of prefabricated board combined cast-in-situ concrete and considers structure and ground
Underground pipe gallery construction method, this method is needed since road surface it can be seen from its process, and piling, open cut are cast-in-place to bottom plate, wet
Operation causes the construction time still longer, is unfavorable for lightweight, large area operation.
Summary of the invention
In order to overcome the above technical defects and insufficient, the present invention provides a kind of jigsaw assembled pipe gallery and construction party
Method, solve traditional cast-in-place concrete piping lane need situ wet operation, pollution is big, be unfavorable for industrialization, industrialization production, manually at
