Description
Technical field
The present invention relates to the attachment structure of the interval service channel of subterranean tunnel, more particularly to one kind are suitable to push pipe implements connection
The lining cutting attachment structure of network passage.
Background technology
The construction method of interval service channel mainly has:Subsurface excavation method after cut and cover method, subsurface excavation method and first open cut, due to urban district
Construction site is narrow and small, does not allow to block the traffic and effect on environment, in soft clay area frequently with freezing process.The construction freezing method soil body
Intensity is high, construction safety, but operating expenses is higher, long construction period, to there is special freezing equipment and technical personnel, and
Pollute the environment.Therefore in the case where the duration is nervous and environmental requirement is increasingly improved, how quickly, safe and environment-friendly, efficiently
Construction is completed, the key for interval service channel engineering construction is become.
Push bench process is a kind of construction method of the laying underground piping of no-dig technique, by means of main top oil cylinder and pipeline relay well
Deng jacking force, make tool pipe or development machine from working pit through soil layer, and shift onto sling in reception hole always, while will be tightly
With buried pipeline after tool pipe or development machine.Constructed service channel from the method for tunnel lateral jacking using push bench process, work of constructing
Make that face is little, noiselessness, speed is fast, equipment it is repeatable utilize, environmental protection, therefore should widely popularize.But in practice of construction, due to connection
Network passage and the main tunnel duct piece open area of the structural attachments in main tunnel are big, and link node is difficult to carry out, and for waterproofing design
Weak link.Thus main tunnel is connected design with push pipe service channel and becomes to restrict the crucial ring of construction by pipeline jacking method service channel
Section.
The present situation of this area correlation technique：
The construction procedure of existing shield interval Freezing Method for Cross-passage Construction is as follows：
1) construction main body running tunnel, in service channel position Fourth Ring steel pipe sheet is arranged altogether, wherein middle two rings are loopful
Steel pipe sheet, the ring of both sides two respectively arranges one piece of steel pipe sheet for service channel position, and remaining block is concrete pipe sheet；
2) using construction freezing method service channel position soil layer；
3) treat after the completion of freezing soil, withdraw from refrigeration process equipment, open the steel pipe sheet of service channel position, form tunneling
Passage ingate；
4) subsurface excavation method implements service channel hair hole, pours into a mould service channel liner structure；
5) implement service channel and main tunnel link position structure, form integral cast-in-situ structure.
But but there is following defect in this freezing process：
Construction freezing method service channel needs using steel pipe sheet, needs a series of technical contingent of refrigeration plants, specialty, applies
The work cycle is long, and operating expenses is high, and periphery soil body generation environment can be polluted in freezing process, and needs to be applied using subsurface excavation method
Work.Therefore the duration is nervous, in the case that automatization and environmental requirement increasingly improve, how quickly, safe and environment-friendly, efficiently
Construction is completed, the key for interval service channel engineering construction is become.
