Description
Technical field
The present invention relates to urban track traffic and shield tunnel project technical field, specially a kind of sliding steel bushing shield
Machine, which integrally misses the stop, secondary originates construction method.
Background technique
In multiple continuous tunneling constructions in shield section, shield machine is according to transition mode, it usually needs large-scale crane is adopted
Secondary originate is carried out again with disintegrating, hanging out to re-assembly again.If closing, which is completed, in station construction hangs out condition there is no reserved,
Or centre station construction field condition is complex, Large-scale Hoisting, transporting equipment disengaging field are difficult, still need to consume using the method
It is time-consuming compared with long, costly, risk is big, economy is poor, therefore, saved by the way of technique on shield machine's station-crossing in this case
About duration and construction cost at home and abroad have many successful cases at present, but directly utilize steel bushing after receiving using steel bushing
Cylinder integrally miss the stop together with shield machine it is settled it is modern thus not yet.It is inherently a kind of using steel bushing balance reception Originating Technique
More complicated, novel construction technology has strict requirements to installation, the dismounting of steel bushing, reinforces and receive with shield end
It originates and compares, the process hung out is removed in more one of steel bushing installations of shield lifting, and construction technology is more complicated, cumbersome.Pass through
In built station base plate paving sliding rail, withstood on using hydraulic jack whole to steel bushing and shield machine on the track laid
Body is lifted, is moved, to realize that shield machine and steel bushing integrally miss the stop.This technology, which efficiently solves shield machine, not to be had
The station of standby lifting condition is completed to miss the stop the technical problem of construction, and can be saved the duration, is reduced cost, has been evaded shield machine and arrived
It many and diverse preparation such as re-assemblies, debug after up to originating terminal, being a kind of safety, economic, quick construction technology, saving is applied
10 days/time of the work duration or so.
Such as Chinese Patent Application No. are as follows: a kind of shield sky of the patent disclosure of CN201811258119.3 is pushed away through tunneling tunnel
Road and the secondary construction method and its structure originated, by leading in concrete guide table of the bored tunnel bottom pouring with hole
It is laid with track on platform, steel corbel is installed in hole, pushes away stepping with jack collective effect using steel corbel for shield sky and provides
Reaction force realizes that the efficient sky of shield pushes away and passes through bored tunnel；It, will be pre-buried separately by bored tunnel secondary lining pre-embedded steel slab
Steel plate, the support of fashioned iron counter-force connect with the rigid boxing of counter-force, provide counter-force support for secondary originate of shield, make shield in bored tunnel
It is smoothly secondary to originate.The present invention is directed to bored tunnel narrow space, and construction is limited vulnerable to various aspects, pre-buried by ingehious design
Part and reserved cavity, and counter-force frame system etc. is improved, is optimized.But the main purpose of the invention is to pass through tunneling
Tunnel ressemble shield machine complete it is secondary originate, integral construction amount is larger, for being affected for tunnel structure, consumes simultaneously
Shi Jiu.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of sliding steel bushing shield machine integrally miss the stop it is secondary
Construction method is originated, is integrally missed the stop secondary the step of originating construction for simplifying shield machine.
The sliding steel bushing shield machine integrally miss the stop it is secondary originate construction method, include the following steps:
Step 1, preparation of construction operates:
Step 1.1, review measures station headroom size, it is desirable that needed for station headroom size is greater than steel bushing cylinder size and retains
Working space；
Step 1.2, levelling in shield reception end well using horizontal measuring instrument, steel bushing is installed, shield machine driving enters
Steel bushing, last assembled endless tube piece simultaneously carry out slip casting closure, complete shield and receive；
The cable and pipeline on shield machine are identified, the cable between shield machine and rear mating trolley is broken with pipeline
It opens, separates shield machine with rear mating trolley；
With the connection between the transition rings and portal ring of oxygen welding cutting steel bushing, steel bushing rear end seal cover is opened, clearly
Manage cutterhead, cutter soil, check cutterhead, cutter abrasion condition and replace the cutter of serious wear；
Step 1.3,3 groups of longitudinal rail of totally 6 slidings are laid with along former tunneling direction on standard paragraphs bottom plate AT STATION, using straight
22 spiral of diameter φ implantation bottom plate is fixed, and is arranged at points 3, is respectively placed in steel bushing pedestal two sides and middle part, 2, every place, and two
Patch is supported between root；
Circular hole is bored on the web of the rail for sliding longitudinal rail with rail bonding drill, the circular hole of 3 diameter phi 20mm is 1 group, often
Spacing between group is 400mm, and circular hole spacing is 100mm；
Step 2, steel bushing and technique on shield machine's station-crossing are slid:
Step 2.1,4 100t hydraulic jacks are respectively installed in steel bushing pedestal two sides, using hydraulic jack by shield
Machine is lifted at least 160mm together with steel bushing pedestal；
Step 2.2, it is laid with 10mm thick steel plate in steel bushing base bottom, on the steel plate transversely parallel laid 8 removals
Lateral rail；Circular hole is bored on the web of the rail of the lateral rail of removal at both ends with rail bonding drill, the circular hole of 3 diameter phi 20mm is
Spacing between 1 group, every group is 400mm, and circular hole spacing is 100mm；The coating butter on removing lateral rail；
Step 2.3, steel bushing pedestal and shield machine are placed on the lateral rail of removal by hydraulic jack；
Step 2.4, on the removal transverse direction rail at both ends, steel bushing base side installs 2 100T cross by one end of wall
It is synchronous to push steel bushing pedestal and shield machine to the center transverse translation that misses the stop to pipe bending cylinder；
Step 2.5, after steel bushing pedestal and shield machine transverse translation 2175mm to designated position, 8 100t are utilized again
Steel bushing pedestal is lifted by hydraulic jack, takes out the removal transverse direction rail under steel bushing pedestal, and is laid with that split heads, to remove end vertical
To rail.
Step 2.6, shield machine vertical shift is missed the stop:
On removing end longitudinal direction rail and the longitudinal rail of sliding after coating butter, pass through circle on two side slip longitudinal direction rail
Reaction support is arranged in hole, fixes 2 longitudinal direction 100t pipe bending cylinders, withstands steel bushing pedestal two sides, synchronous push steel bushing pedestal
It moves forward with shield machine；
When longitudinal pipe bending cylinder reaches range, lower longitudinal pipe bending cylinder is dismantled, installation increases a pushing tow stroke
