Description
Technical field
The related closed technical field of quick supporting that the utility model relates to TBM at passing fault crushed zone stratum, specifically
It is related to a kind of fault belt stratum quick supporting closing template.
Background technique
Open type complete-section tunnel boring machine (TBM) is quick with it, efficient.The advantages that environmentally friendly, on mountain tunnel and ground
It is widely used in iron project, is compared with previous artificial drilling and blasting method, greatly enhance construction efficiency, also obtain
Good application effect.But it is bad that fault belt, rich water, high-ground stress etc. can be usually encountered in TBM tunneling process
Geology, especially usually can be stranded there is a situation where TBM card machine in rock crusher location.In order to get rid of poverty as early as possible, TBM is made to get rid of danger
Danger, needs to taste methods various to the greatest extent.
Currently, TBM commonly gets rid of poverty, method mainly has side heading method, service gallery method, blasting procedure, equipment technology reconstruction
Method, equipment retrogressing method etc..But above-mentioned several method is not available large scale equipment in most cases and carries out field operation, needs
Scarfing cinder processing is manually carried out, there is heavy workload and there are problems that construction risk.Meanwhile general fault belt is also adjoint
The outflow of relatively large crevice water, and water exit position is very irregular, brings great difficulty to artificial scarfing cinder operation, makes
Working environment becomes quite severe.By a large amount of engineering practice which kind of shows no matter to take get rid of poverty measure, always faces a large amount of
Scarfing cinder work, delayed the progress of construction, while the also risk buried of meet machine significantly.Think through researching and analysing, it is main
If causing fault belt stratum largely to be collapsed caused result because the supporting of TBM During Initial Stage Construction is not prompt enough.
Summary of the invention
The purpose of this utility model is against the above deficiency, to provide a kind of fault belt stratum quick supporting closed die
Plate, to solve the problems in above-mentioned background technique.
The technical solution of the utility model is achieved in that a kind of fault belt stratum quick supporting closed die
Plate, it includes upper former be prepared by high-strength polyethylene plastics, the fan-shaped structure of section, and is co-axially located at
In upper former intrados, the fan-shaped structure of section lower template；Along upper former ring in the plate face of the upper former
To drainage hole combination water seepage hole group has been uniformly arranged in a manner of interval, each drainage hole group is by multiple along upper former axis
To the drainage hole composition being uniformly arranged, each water seepage hole group is by multiple water seepage hole groups being axially uniformly arranged along upper former
At；There is cavity at interval between the upper former and lower template, on the cavity end edge of upper former Yu lower template two sides
Upper and lower layer template axis direction is uniformly packaged with multiple drainpipes respectively, so that upper former and lower template collectively form one
A overall structure.
Further, the diameter of the drainage hole is greater than the diameter of water seepage hole.
Further, individual drainage holes in the drainage hole group are step counter bore structure.
Further, the upper former is identical as the radian of lower template.
Further, it is greater than the outer of the drainpipe on the left of lower template in the internal diameter for the drainpipe being located on the right side of lower template
Diameter is convenient for socket joint when template splicing to use.
The principles of the present invention are: the material that the template of the utility model uses is high-strength polyethylene engineering plastics,
The plastics have the engineering characteristics such as odorless, nontoxic, environmentally friendly, and this kind of plastics are by polyvinyl resin with super-high molecular weight by certain
Mold machine-shaping, there is preferable toughness and intensity；The template is divided into upper layer and lower layer, and the upper and lower all have one
Fixed thickness, the thickness of entire template are greater than the thickness that upper layer panel is added with lower layer panel, i.e. template is hollow structure, is convenient for
Collect the crevice water on the wall of hole；Wherein upper former is hollow design, i.e. upper former is by big drainage hole and small infiltration
Hole distributes alternately, and can be according to different Proportionality designs.Drainage hole and water seepage hole are alternately distributed, and are guaranteeing upper former intensity
While, moreover it is possible to guarantee that the drain function of entire template is normal, is unlikely to the case where drainage hole and water seepage hole occur while blocking.
And individual drainage holes periphery of eating dishes without rice or wine has the designs (i.e. step counter bore structure) of enlarged openings, this is conducive to broken sillar herein
Place's support forms channel, and drainage hole is unlikely to block；Lower template is solid design, and the purpose of the design mainly prevents mould
The water flow collected in plate leaks out, and the water flow for only allowing to collect is discharged from the drainpipe of the left and right sides of template, is conducive to control in this way
The flow direction of water flow processed is discharged according to the outlet pipeline of design, very useful to the operating environment improved in hole, makes operation people
The working environment of member is unlikely to too moist；Designing at lower template in the left and right ends of template has several drainpipes, row
Water pipe is particularly located at the position for being close to lower template, is distributed according to the even width of template.Furthermore, it is contemplated that in work progress
The Bonding Problem of template, the drainpipe design diameter at left and right sides of template is different, the diameter of right side drainpipe less times greater than
Left side, to play the role of socket joint when template splicing.
Compared with prior art, the utility model has the following beneficial effects:
The utility model has by the upper former of template, the lower template of template, drainage hole, water seepage hole, drainpipe
Effect combination forms the structure letter of the utility model for the template of fault belt stratum TBM driving quick closure support
It is single, it is practical, it can solve the problems, such as that scarfing cinder amount in fault belt stratum is big and crack water flowing is irregular from source, both
Reduce and manually check heavy manual labor, and improves the operating environment of worker in hole.While guaranteeing safety driving,
Improve the working efficiency of TBM driving.
