Abstract
The invention provides a pressurizing grouting method utilizing an air bag blockage device. The method includes the steps that the air bag blockage device is mounted at the end of a soil nail or the end of an anchor rod, then the air bag blockage device is inflated to block a hole opening, and hole bottom pressurizing grouting is conducted in the soil nail or the anchor rod, so that poured pulp is in tight contact with the side wall of a formed hole; and after the poured pulp is solidified, air in the air bag blockage device can be exhausted to be recycled and reused. By the adoption of the pressurizing grouting method, the soil nail grouting effect or anchor rod grouting effect can be improved, and pulling resistance is improved; and meanwhile, after the poured pulp is solidified, the air bag blockage device can be recycled and reused after the air in the air bag blockage device is exhausted. The grouting method plays a substantial role in improving grouting quality of the soil nail or the anchor rod.
Description
[technical field]:
The present invention relates in Geotechnical Engineering the closure of soil nailing or anchor pole and grouting under pressure。
[background technology]:
The closure of air bag plugging device and slip casting effect that soil nailing or anchor pole carry out grouting under pressure are its application and the key promoted, at present the slip casting of soil nailing or anchor pole is realized mainly through the method for Dumpage type, and be generally adopted slip casting bag and carry out closure to improve grouting quality。But said method is unreliable because of plugging effect, it is impossible to substantial raising blocks and slip casting effect。
[summary of the invention]:
It is an object of the invention to improve the plugging effect in soil nailing or anchor pole aperture, improve the mortar depositing construction quality to soil nailing or anchor pole and effect, it is ensured that the effect of Foundation Pit Support Design purpose and saving cost。
A kind of by utilizing the grouting under pressure method of air bag plugging device, it is characterized in that: first design a kind of air bag plugging device that soil nailing and anchor pole are carried out grouting under pressure, this device is cylindrical hollow shape, its crust is quality of rubber materials, exhaustor jack, rubber bar jack and Grouting Pipe jack are left in inside, and 3 is hollow between jack and crust, two ends are lid skin, and the lid skin of one end has inflation inlet；The reinforcing bar of soil nailing or anchor pole or steel strand wires one end are inserted in the hole of pore-forming, and the other end inserts in rubber bar, and then rubber bar is inserted in rubber bar jack, and exhaustor inserts exhaustor jack, and Grouting Pipe inserts Grouting Pipe jack；Being inflated air bag plugging device afterwards expanding contacting with the hole wall soil body, soil nailing or anchor pole pore-forming aperture are blocked, carries out grouting under pressure by Grouting Pipe, exhaustor is exhausted simultaneously。
Further, the air pressure that air bag plugging device is inflated is 1.0Mpa to the maximum, and the pressure of grouting under pressure is 0.5～1.0Mpa。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 pore-forming, air bag plugging device is inflated, block aperture。
To carrying out grouting under pressure at the bottom of hole in soil nailing or bolthole, make slurry and the close contact of pore-forming sidewall of injection。
After slurry solidification to be implanted, the gas discharging in air bag plugging device can be recycled and reused。

[detailed description of the invention]:
In conjunction with accompanying drawing, the implementation process of the present invention is illustrated。A kind of simplicity and plugging effect are reliable, it is possible to increase the air bag plugging device of slip casting effect, and air bag is connected and composed by quality of rubber materials lid skin 1, quality of rubber materials crust 4, quality of rubber materials endothelium 7, inflation inlet 2 sulfuration, and whole balloon length is 500mm, and diameter is 150mm。Be respectively adopted soil nailing rubber bar 8 according to air bag in the purposes difference of soil nailing or anchor pole, anchor pole rubber bar 9 carries out being mounted to rubber bar jack 5, and rubber bar length is 500mm, and diameter is 50mm。By the reinforcing bar of respective model during soil nailing slip casting, insert reinforcing bar jack 10, the diameter of reinforcing bar jack 10 is reserved according to bar diameter, during bolt grouting, the steel strand wires of corresponding radical are inserted steel strand wires jack 11, the number of steel strand wires jack 11 is processed according to different-diameter and radical, and diameter is reserved according to steel strand wires model。Insert exhaustor respectively by exhaustor jack 3 and Grouting Pipe jack 6 and Grouting Pipe completes the installation of air bag plugging device。Operation principle is: the air bag being completed is put into soil nailing or the aperture of anchor pole pore-forming, it is inflated closure aperture to inflation inlet 2, makes quality of rubber materials crust 4 and the hole wall soil body be in close contact, make quality of rubber materials endothelium 7 and exhaustor, Grouting Pipe, rubber bar close contact。By Grouting Pipe to carrying out grouting under pressure at the bottom of hole in soil nailing hole。After slurry solidifies, discharge the gas in air bag by inflation inlet, remove and reclaim air bag and rubber bar。
A kind of by utilizing air bag plugging device, to carrying out the method for grouting under pressure at the bottom of hole in hole, simplicity and plugging effect are reliable, it is possible to increase slip casting effect, whole system is made up of air bag plugging device 21, exhaustor 22, Grouting Pipe 23, reinforcing bar or steel strand wires 24。
It is respectively adopted reinforcing bar or steel strand wires in the purposes difference of soil nailing or anchor pole according to air bag, mounted above-mentioned system is put into pore-forming, by to air bag plugging device 21 inflation closure aperture, by Grouting Pipe 23 to grouting under pressure at the bottom of hole, grouting pressure is generally 0.5～1.0Mpa, slurry can be returned by exhaustor 22 after being full of slurry in hole, close exhaustor 2 when occurring returning slurry and continue grouting under pressure in hole, complete slip casting rear enclosed Grouting Pipe 23, prevent slurry from overflowing from Grouting Pipe 3, after slurry solidifies in hole, air bag plugging device 21 exitted and reclaim。
Operation principle is: will put into the aperture of pore-forming with the soil nailing of air bag plugging device or anchor pole, to air bag plugging device inflation closure aperture, by Grouting Pipe to carrying out grouting under pressure at the bottom of hole in soil nailing hole。By discharging the gas in air bag plugging device after slurry solidifies, remove and reclaim air bag plugging device。
