Description
Technical field
The utility model relates to a kind of support system, especially a kind of open type TBM support system.
Background technique
Tunneling boring TBM(rock tunnel(ling) machine) integrate mechanical, electrical, hydraulic, control, measuring technique is, it can be achieved that tunnel
Excavation, muck removal, supporting are worked continuously.Relative to traditional drill+blast tunnel Construction Mode, TBM(rock tunnel(ling) machine is utilized)
It constructs safer and more reliable, efficient, environmentally friendly, has been widely used in the engineerings such as water conservancy and hydropower, rail traffic, municipal administration.It uses
TBM(rock tunnel(ling) machine) construction, the changing factor of geology should be fully taken into account, it is ensured that development machine had both had the energy of speedy drivage
Power, and there is the ability of the quick supporting under unfavorable geological condition.
The previous Open TBM Tunnel Construction Schedule and an important technical problem of safety of restricting is exactly to encounter tomography
When the unfavorable geologies such as crushed zone, once excavating hole section exposes TBM shield, it may appear that a large amount of slump rubbles and drift sand, not only to TBM
Equipment and operating personnel's safety belt are to threaten, and largely the rock ballast of slump accumulates hole bottom, considerably increases hole bottom scarfing cinder amount, often
Often resulting in after TBM shuts down waiting scarfing cinder could tunnel.Thus reduce TBM utilization rate of equipment and installations, reduce TBM construct into
Ruler increases TBM construction period and cost.Analyzing reason is mainly previous open type TBM construction supporting method existing defects, i.e.,
When encountering the unfavorable geologies such as crushed zone or alteration zone in construction, the support pattern taken i.e. steel arch-shelf, steel mesh, reinforcing bar row and
Suspension roof support etc. is unable to continuous effective supporting, and when TBM is tunneled forward, TBM shield occurs being interrupted and discontinuous, rigid dew with country rock
The fractured rock of shield continuous in time, cannot be supported effectively and slump out.
Utility model content
The purpose of this utility model is just to provide a kind of open type TBM support system for being able to carry out continuous effective support.
The purpose of this utility model is that technical solution in this way is realized, a kind of open type TBM support system, including
Girder and shield are vertically arranged with lifting body on the girder and close to shield one end, are arranged on the lifting body
There is steel plate, the steel plate outer wall is provided with steel arch-shelf.
Wherein, the lifting body includes the jacking cylinder being vertically arranged on girder, is arranged on the jacking cylinder
There is support frame, the steel plate is located at support frame as described above upper surface.
For the ease of dismantling and conveniently connecting with jacking cylinder, support frame as described above includes left support frame and right support frame,
The left support frame and right support frame are vertically arranged in the upper surface both ends of jacking cylinder respectively.
For the ease of connecting adjacent steel plate, the steel plate is at least two, and is located at left support frame and right support frame
On, the vertical arch of spelling is provided between the adjacent steel plate.
Dregs in order to prevent is vertically arranged with shield baffle in the front end of the shield.
By adopting the above-described technical solution, there is the utility model structure to be simple and convenient to operate, is low-cost excellent
Point, using it can continuous effective support, realize in time closing rock stratum, reduce vault slag-off, improve construction efficiency.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the construction schematic diagram of the utility model；
Fig. 2 is the front view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in Figure 1, 2, a kind of open type TBM support system, including girder 1 and shield 2, in the girder
It is vertically arranged with lifting body on 1 and close to 2 one end of shield, steel plate 3 is provided on the lifting body, in the steel plate 3
Outer wall is provided with steel arch-shelf 4.
Wherein, the lifting body includes the jacking cylinder 5 being vertically arranged on girder 1, is set on the jacking cylinder 5
It is equipped with support frame, the steel plate 3 is located at support frame as described above upper surface.
Further, for convenience carry out disassembly and the connection with jacking cylinder, support frame as described above include left support frame 6
With right support frame 7, the left support frame 6 is vertically arranged in the upper surface both ends of jacking cylinder 5 with right support frame 7 respectively.
The steel plate 3 is at least two, and is located in left support frame 6 and right support frame 7, in the adjacent steel plate 3
Between be provided with the vertical arch of spelling.
Dregs in order to prevent is vertically arranged with shield baffle 8 in the front end of the shield 2.
Work progress of the present invention is as follows:
When construction, which encounters the unfavorable geologies such as crushed zone, alteration zone, needs closing rock stratum in time, steel plate 3 is laid in support
On frame, support frame is tunneled with TBM and steel plate 3 is moved forward with TBM, closes rock stratum in time, reach 3 width of steel plate to driving distance
Afterwards, support frame and 3 entirety of steel plate are jacked upwards to design section using jacking cylinder 5, is then spelled in support frame gap vertical
Arch.This support system can close rock stratum in time, and it is scaling-off to be effectively reduced vault, saved scarfing cinder support time, mentioned significantly
High TBM construction efficiency.
Steps are as follows for its Specific construction: (1) installing steel plate 3 to left support frame 6 and right support frame 7；(2) jacking is adjusted
5 height of oil cylinder is in close contact left support frame 6, right support frame 7 and steel plate 3 and steel arch-shelf 4 and shield 2；(3) TBM driving away from
After reaching 3 width of steel plate, stop driving；(4) vertical arch 9 is spelled in setting among left support frame 6,7 gap of right support frame；(5) it spells
Vertical arch 9 and steel arch-shelf 4 are spelled using rigid structure connection after the completion of vertical arch 9；(6) jacking cylinder 5 is withdrawn, so that left support frame
6, right support frame 7 is detached from steel plate 3；(7) left support frame 6, right support frame 7 are removed, step (1)-(6) is repeated, constantly constructs
Operation.
