Abstract
The utility model provides a through anti - dead -weight loading slip casting device that utilizes gasbag plugging device which characterized in that: including gasbag plugging device, gasbag plugging device is cylindric cavity shape, and its crust is the rubber material, and the blast pipe jack is left to inside, and rubber bar jack and slip casting pipe jack are cavity between 3 jacks and the crust, and there is the inflation inlet at both ends for to cover the skin on the lid skin of one end, during the reinforcing bar of soil nail or stock or the downthehole other end that the inclination pore -forming was inserted to steel strand wires one end insert the rubber bar, then in rubber bar reinsertion gasbag plugging device's the rubber bar jack, the blast pipe inserts the blast pipe jack, and the slip casting pipe inserts slip casting pipe jack. The slip casting effect of multiplicable soil nail of the device or stock improves the withdrawal resistance. Simultaneously, wait that the slurry that pours into into solidifies the back, can retrieve reuse to the gasbag device with behind the gaseous emission among the gasbag plugging device.
Description
[technical field]
This utility model relates to the antigravity grouting under pressure in Geotechnical Engineering to soil nailing or anchor pole.
[background technology]
Soil nailing or anchor pole are carried out grouting under pressure air bag plugging device closure and antigravity slip casting effect be its application and
The key promoted, not perfect to the plugging technology of the antigravity slip casting of soil nailing or anchor pole at present, it is impossible to substantial raising is sealed
Block up and the effect of antigravity slip casting, cause grouting quality to be difficult to meet design requirement.
[summary of the invention]
The purpose of this utility model is to improve soil nailing or the plugging effect in anchor pole aperture, and solving pore-forming is updip angle
Soil nailing or anchor pole because slurry self gravitation is excessive cannot the problem of slip casting, and improve the antigravity slip casting to soil nailing or anchor pole and execute
Working medium amount and effect, it is ensured that design of its support purpose and cost-effective effect.
It is a kind of by utilizing the antigravity grouting under pressure device of air bag plugging device, it is characterised in that: include that air bag blocks
Device, air bag plugging device is cylindrical hollow shape, and its crust is quality of rubber materials, and exhaustor jack, rubber bar are left in inside
Jack and Grouting Pipe jack, 3 is hollow between jack and crust, and two ends are lid skin, and the lid skin of one end has inflation inlet；Soil nailing
Or the other end inserts in rubber bar in the hole of the reinforcing bar of anchor pole or steel strand wires one end insertion top rade pore-forming, then rubber bar is inserted again
Entering in the rubber bar jack of air bag plugging device, exhaustor inserts exhaustor jack, and Grouting Pipe inserts Grouting Pipe jack.
Being inflated air bag plugging device, closure aperture carries out aperture antigravity in hole by Grouting Pipe and adds pressure injection
Slurry, exhaustor is exhausted simultaneously.
Further, its mechanism meets relationship below:
..........................................................................①
Or..........................................②
Wherein: Pz grouting pressure

Air bag plugging device is installed in soil nailing or anchor pole front end.
After soil nailing or rockbolt installation air bag plugging device, put into soil nailing or anchor pole pore-forming that pore-forming is updip angle
In, air bag plugging device is inflated, blocks aperture.
To carrying out the aperture grouting under pressure in antigravity direction in soil nailing or bolthole, make the slurry of injection not because of self gravitation
Flow out in hole, and be in close contact with pore-forming sidewall.
After slurry solidification to be implanted, the gas in air bag plugging device can be discharged and recycle and reuse.

[detailed description of the invention]
In conjunction with accompanying drawing 1, implementation process of the present utility model is illustrated.
A kind of by utilizing air bag plugging device, to carrying out the technology of aperture antigravity grouting under pressure in hole, easy and envelope
Stifled reliable for effect, it is possible to increase slip casting effect, whole system by air bag plugging device 21, Grouting Pipe 22, exhaustor 23, reinforcing bar or
Steel strand wires 24, the hole 25 that sets of top rade are constituted.
It is respectively adopted reinforcing bar or steel strand wires in the purposes difference of soil nailing or anchor pole, by mounted above-mentioned soil nailing according to air bag
Or anchor pole put into top rade set hole 25, by air bag plugging device 21 inflation closure aperture, utilize Grouting Pipe 22 to
Aperture antigravity grouting under pressure, can return slurry by the exhaustor 23 goed deep at the bottom of hole after being full of slurry in hole, envelope when there is returning slurry
Close exhaustor 23 and continue grouting under pressure in hole, complete slip casting rear enclosed Grouting Pipe 22, prevent slurry from overflowing from Grouting Pipe 22, treat
Air bag plugging device 21 is exitted after solidifying in hole and reclaims by slurry.
Operation principle is: is put into top rade and sets the hole in hole 25 by soil nailing or the anchor pole with air bag plugging device, to
Air bag plugging device inflation closure aperture, by Grouting Pipe 22 to carrying out aperture grouting under pressure in soil nailing hole.After slurry solidifies
By discharging the gas in air bag plugging device, remove and reclaim air bag plugging device.
This by utilizing the antigravity grouting under pressure technology of air bag plugging device, simple in construction, cheap, install and
Convenient disassembly.Obtain reliable antigravity grouting under pressure effect by air bag plugging device, improve plugging effect, to overall work
Cheng Tigao construction quality plays substantive significance.
