Description
Technical field
The present invention relates to the construction method of a kind of heavy caliber rain sewage conduct assembled modular construction.Belong to municipal works field, it is adaptable to the burial and construction of heavy caliber rain sewage conduct.
Background technology
Municipal administration rain sewage conduct is as infrastructure important in cities and towns, and daily life and work relationship with resident are close.At present in municipal administration rain sewage conduct construction, rain sewage pipe is layed in the both sides of town road more, work on the spot face is less, cause tubing to lift rear hanging belt in place and be not easy extraction, the globality of pipeline is poor, steadiness is low, and easily causes pipe skew, it is impossible to ensure the straight cis degree of Pipe installing, twice basis concrete construction cycle is long simultaneously, and pipeline is the most on the low side with the bonding strength on basis.
There is now multiple assembled pipe support structure, and under suitable operating mode, all achieve preferable project benefit, but remain and improve space, it is mainly reflected in: ground is not processed by (1), directly carry out pipe support installation, cause foundation bearing capacity deficiency that differential settlement occurs；(2) portion of standoff structure does not considers conduit section size, easily forms bigger space between pipeline and bearing, and support strength is on the low side after having constructed；(3) portion of standoff structure does not considers connectivity problem between bearing space grouting behind shaft or drift lining, split-type bearing, affects the overall stress of pipeline and bearing；(4) without adding epistasis connection measure, pipe shaft cracky etc. in the case of producing settlement after construction after lifting pipeline is completed by portion of standoff structure.
Given this, for lifting construction difficulty present in tradition heavy caliber rain sewage conduct construction, overall steadiness is low and pedestal bonding strength not enough, produces technological difficulties and the problems such as differential settlement drawing crack after pipeliner after Pipe installing, needs invention a kind of lifting construction simplicity, overall structure good stability, support strength height, rain sewage conduct assembled modular construction that economic benefit is excellent at present badly.
The heavy caliber rain sewage conduct assembled modular construction of the present invention is used prefabricated pipeline pedestal and is effectively enhanced globality and the stability of Pipe installing by a series of reinforcement measures, and structure hoisting is convenient, has preferable economic technology benefit.
Summary of the invention
It is an object of the invention to provide a kind of efficiency of construction height, the construction of the lifting pipeline heavy caliber rain sewage conduct assembled modular construction that steadiness is good, differential settlement is little simple, overall.
