Description
Technical field
The present invention relates to underground pipe galleries, are integrated more particularly to a kind of full prefabrication and assembly construction superposed type empty stomach wallboard underground
The construction method of piping lane.
Background technology
Now, numerous advantageous characteristics such as Urban Underground pipe gallery is comprehensive with its, long-term effect, maintainability, the feature of environmental protection,
By extensive use more and more.Promotion with people to pipe gallery performance requirement, Pipe rack is increasingly complicated, construction week
Phase is increasingly longer, and traditional construction technology has been difficult to meet new requirement, particularly with long range, multi-section complicated construction condition
Under underground pipe gallery, it is proposed that more harsh construction requirement.
Underground pipe gallery generally use integral cast-in-situ construction method, due to the binding of this method scene reinforcing bar, template paving
And if concreting quantities is big, usual difficulty of construction is big, and the period is long, of high cost, as an improvement, it has been proposed that prefabrication and assembly construction
Method is to improve construction technology, wherein piping lane is split as the basic prefabricated components of board wall, assembly at the scene shapes, finally by
Overlapping cast-in-place concrete, which forms integrally-built prefabrication and assembly construction superposed type mode of construction, has numerous advantages, but due to this construction
Mode still belongs to the starting stage at home, and relevant codes and standards are not yet complete, and construction experience also accumulates deficiency, gives Practical Project item
Mesh practice proposes huge challenge.
Invention content
