Service channel in urban subway tunnel is usually located at the busy road in city in the following, this traditional methods, which seriously exists, interferes ground
Face communal facility, duration are compared with the problems such as long, risk is big, uneconomical.
City track traffic engineering branch company of Shanghai Civil Engineering Co., Ltd. of Crec by comparing various arrangement and method for construction,
The technical solution of service channel shield construction is proposed, service channel development machine has stronger geological adaptability, both can be with
Can also be tunneled in weak soil in ground consisting of hard rock, be not a concern level of ground water height, can in a variety of underground gas environment work
Make, greatly avoid down town building and destroyed caused by surface subsidence, the program can greatly shorten the duration, reduce cost.
It in shield method tunnel construction, slags tap for earth pressure balanced shield, EPBS construction, is to be turned dregs using belt conveyor
It is transported in slag-soil truck；Slag tap for slurry balance shield construction, extended using hose reel or hydraulic pressure steel bushing.But
That in shield method Freezing Method for Cross-passage Construction, shield host and rear mating trolley are separate design, shield host with lining cutting assembly not
Disconnected to move ahead, mating trolley is rested in tunnel, is not moved ahead into service channel, therefore is caused in shield method tunnel construction therewith
The existing mode of slagging tap be not applied for the construction of shield method service channel；Wherein, belt conveyor is regular length, it is impossible to suitable
Preferably continuous extended dregs operative line；Hose reel is the conveying for being not suitable for flowing plasticity dregs to convey liquid；Hydraulic pressure steel
Although sleeve can extend, it is smaller, it is necessary to spreading repeatedly that it extends ratio, it is impossible to adapt to the work rhythm of shield host.
The content of the invention
The present invention is to avoid the deficiency present in the above-mentioned prior art, provides a kind of shield method service channel and goes out slag system
System is slagged tap requirement with the construction for adapting to shield method service channel, is ensured that the work section of shield host gathers, is improved construction efficiency.
The present invention adopts the following technical scheme that solve technical problem：
Shield method service channel slag-tapping system of the present invention, feature are：
The screw conveyor of rotary joint is provided with, rotary joint head and the tail phase is utilized between adjacent two sections of screw conveyors
Company forms " V " shape supply unit, joins end to end between adjacent " V " supply unit also with rotary joint and forms multistage spiral transferring
Send the slag-tapping system that machine is connected in series；Stretching, extension or contraction of the slag-tapping system in delivered length can be made by rotating rotary joint；Institute
The first section screw conveyor in slag-tapping system is stated with shield host mobility and is used as slag-tapping system entrance, latter end screw conveyor
It is connected with the platform machine rested in tunnel as slag-tapping system outlet section, realizes the distance variable of transport dregs.
Shield method service channel slag-tapping system of the present invention, feature are lain also in：
It is set in the bottom of service channel along the preceding line direction of shield host and track, the bottom of each " V " supply unit is set
Carriage supports are utilized respectively on the sliding rail, the balladeur train can be moved along the track.
Shield method service channel slag-tapping system of the present invention, feature are lain also in：
Connection nozzle position between each section of screw conveyor sets the nozzle laterally protruded out, will using rotary joint
The nozzle that a pair laterally protrudes out is docked；The rotary joint is the link position setting casing in two sections of nozzles, and is installed additional
Sealing ring sets rolling bearing in casing, realizes that the closing between two sections of nozzles is connected using casing and sealing ring, using turning
Dynamic bearing realizes the relative rotation of two sections of nozzles.
Compared with the prior art, the present invention has the beneficial effect that：
The distance of host between rear mating trolley of the invention that effectively solves is unearthed discontinuously under continually changing operating mode
Problem is continuously tunneled so as to fulfill shield, is ensured the controllable of surface subsidence, is drastically increased construction efficiency.
