Description
Technical field
The present invention relates to a kind of half prefabricated assembled pipe gallery spliced with cast-in-place hidden girder and its construction methods.
Background technology
Urban Underground pipe gallery is that the underground of a variety of pipelines such as concentrated setting electric power, communication, combustion gas, feedwater, draining is empty
Between structure.It solves traffic congestion caused by due to " slide fastener road ", avoids aerial " cobweb ", to promoting the total bodily form in city
As creating city harmony ecological environment and playing the role of actively promoting, cause the highest attention of the whole nation from the leadership to the masses.
Traditional complete cast-in-place piping lane form of construction work needs at the construction field (site) to tie up piping lane overall structure progress steel bar meter
The processes such as bundle, formwork, concreting, maintenance and form removal, not only working procedure is complicated, long construction period, and template loss is big, also
The problems such as in the presence of larger raw material storage and processing site is needed, very big fiber crops are brought to construction environment narrow in city
It is tired.
, there is integrated precast Pipe rack and prefabricated in the defects of in order to solve complete cast-in-place piping lane form of construction work
Pipe rack.Integrated precast piping lane has many advantages, such as good integrity, and installation procedure is simple, but there are single-unit size is big, weight
Greatly, transporting and hoisting is not easy, the problems such as the waterproof non insurance of joint.And existing assembled Pipe rack is mostly due to assembling members
More, globality poor is susceptible to the defects of junction structural failure, sealing material damage or aging lead to infiltration in piping lane.
Invention content
