Compared with prior art, the technique effect that the present invention possesses is：This pressure-relieving achor bar designs ingenious, compact conformation, anchor
Bar makes pressure amount big, can allow pressure amount with real-time monitoring anchor pole, and supporting quality is made timely judges it is achieved that " first
The circulation Bracing Process of the strengthening supporting of shield-yield supporting-again ", supporting effect is good, meanwhile, the detachable Posterior circle of bent tube section
Use, saved cost.
Brief description
Fig. 1 be have real-time monitoring allow pressure amount pressure-relieving achor bar structural representation.
Specific embodiment
In conjunction with Fig. 1, the present invention is further described：
A kind of have real-time monitoring and allow the pressure-relieving achor bar of pressure amount, including main rod body 10, the front end setting of described main rod body 10
There is Bower Anchor body 20, described Bower Anchor body 20 is plugged in the grafting chamber 11 of main rod body 10 front end, described Bower Anchor body 20 and main rod body
Connected by spring 30 between 10, described Bower Anchor body 20 is provided with drawstring 21, main rod body 10 is stretched out in one end of described drawstring 21
And be connected with displacement readings unit, described displacement readings unit is used for showing the displacement of drawstring 21；
It is 30cm that the maximum of pressure-relieving achor bar disclosed by the invention allows pressure distance, during use, first injects in the boring being drilled
Anchor Agent, is inserted into mounted anchor pole, hangs up anchor net on tunnel wall, now can be adjusted pre- according to the requirement of actual condition
Jack panel, and then adjust pretightning force.In Bracing Process, when country rock deforms, main rod body 10 and Bower Anchor body 20 can produce
Relative displacement, and compress high-strength spring 30, thus releasing stress it is achieved that yield supporting, during this, drawstring 21 meeting
Produce displacement, and using displacement readings unit, the displacement of drawstring 21 shown, i.e. this anchor pole of this displacement real-time
Allow pressure amount, now, the anchoring quality of anchor pole can be judged according to the actual pressure amount that allows, if find to allow pressure amount be more than 25cm, can lead to
Cross the mode of slip casting again strengthening supporting it is achieved that the circulation supporting of " initial support-yield supporting-again strengthening supporting "
Journey.
This pressure-relieving achor bar designs ingenious, compact conformation, and anchor pole makes pressure amount big, can allow pressure amount with real-time monitoring anchor pole, and
Supporting quality is made and timely judges the circulation supporting it is achieved that " initial support-yield supporting-again strengthening supporting "
Journey, supporting effect is good, and meanwhile, the detachable Posterior circle of bent tube section uses, and has saved cost.
