Description
Technical field
The utility model belongs to technical field of tunnel construction more particularly to a kind of applies for the adjustable of heavy grade tunnel
Work rack.
Background technique
Currently, the prior art commonly used in the trade is such that
Into after 21 century, human society has welcome high speed development.As population, resource, environment and traffic etc. are asked
Topic becomes increasingly conspicuous, Speeding up development Underground Space Resource, makes the whole mankind's second of safety and comfort life on earth
The content that space has become various countries' extensive concern and studies energetically.
With the continuous propulsion of urbanization process, subway construction is also being rapidly developed.In urban center domain, traffic main artery
The daily life of Around resident is not influenced with densely populated location in order not to destroy existing transportation condition, it is more and more
Subway station constructed using subsurface excavation method.And in the tunnel entrance construction in shallow mining method, access tunnel is applied
Generally there are the biggish excavation gradients for work.
When coping with the construction of tunnel heavy grade entrance, conventional method are as follows: when bored tunnel entrance is constructed, by platform
The mode of frame side pad slag continues pad slag reduction rack and inclines to reduce the tilt angle of rack while tunneling movable stand
Tiltedly.This method program is complicated, and pad slag project amount is big, the bad control of gantry angle；And pad slag holding time is longer, gives birth to construction
It produces there are certain interference, work efficiency is caused to reduce；And padding the slag later period need to clear up in time, need to reuse slag-tapping device, cause
The waste of resource.
In conclusion problem of the existing technology is:
When constructing tunnel, the bad control of gantry angle, the mode for padding slag reduces working efficiency, causes the waste of resource.
Solve the difficulty and meaning of above-mentioned technical problem:
The height of the support rod of rack is fixed, and can not carry out the adjustment of angle, pads the engineering that the mode of slag needs
Amount is big, and to construction production, there are certain interference, and pads the slag later period and need to clear up in time, need to reuse slag-tapping device；
In face of increasingly widely used Tunnels in Shallow Buried excavating construction method, constructs in access tunnel and carry out in this link
Invention improves, and production makes the more efficient tool of construction, is just able to satisfy the needs of tunnel development.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of applies for the adjustable of heavy grade tunnel
Work rack increases the versatility of rack, improves economic benefit and working efficiency.
The utility model is realized in this way a kind of adjustable builder's staging for heavy grade tunnel be provided with it is removable
Dynamic rack, removable rack, which is connected by a hinge, diagonal brace I-steel；
Positive and negative silk screw shell both ends screw in plus thread stud and left-hand thread stud respectively, and plus thread stud is connected by hinge
It connects and is fixed on removable rack, left-hand thread stud, which is connected by a hinge, to be fixed on diagonal brace I-steel.
Further, hinge, which is bolted, is fixed on removable rack, can dismantle at any time and move the position of hinge.
Further, through-hole is opened up in the middle part of positive and negative silk screw shell, reinforcing bar or other tools can be inserted into through-hole, side
Just operator is easy to rotate positive and negative silk thread bush.
Further, the outer end of plus thread stud and left-hand thread stud is respectively welded semicircle connecting plate, semicircle connection
Circular hole is offered on plate, is connect respectively with the hinge on removable rack and diagonal brace I-steel by circular hole.
In conclusion the advantages of the utility model and good effect are as follows:
The utility model is a kind of modified bored tunnel digging tool for optimizing access tunnel excavation method, and existing
Technology is compared, and by improving tunnel piercing rack, increases the versatility of rack.It is screwed in respectively just at positive and negative silk thread bush both ends
Threaded stud and left-hand thread stud pass through rotation when plus thread stud and left-hand thread stud are separately fixed on rack and diagonal brace
Anti- silk thread bush become a full member to achieve the purpose that control diagonal brace I-steel angle.Through-hole is opened up among positive and negative silk thread bush, by steel
In muscle or other tools insertion through-hole, operator is easy to rotate positive and negative silk thread bush.By such modified digging tool,
So that when access tunnel excavation construction, the lengthy process for carrying out dregs place mat rack repeatedly, the utility model transformation are avoided
It is low in cost, it is easy to operate, site work environment can be improved, accelerate speed of application under the premise of guaranteeing operation safety.
