Abstract
The utility model is a kind of air bag plugging device carrying out grouting under pressure to soil nailing or anchor pole, by installing air bag plugging device at soil nailing or anchor pole end, it is inflated to air bag plugging device afterwards blocking aperture, carry out grouting under pressure at the bottom of hole in soil nailing or bolthole, the slurry of injection and pore-forming sidewall is made to be in close contact, after slurry solidification to be implanted, the gas discharge in air bag plugging device can be recycled and reused.The utility model device, can increase the slip casting effect of soil nailing or anchor pole, improves withdrawal resistance.Meanwhile, slurry solidification to be implanted, can recycle and reuse after the gas discharge in air bag plugging device to airbag apparatus.Soil nailing or anchor pole are improved grouting quality by this device can play substantial effect, and easy for installation, safe and reliable.
Description
[technical field]
The utility model relates to grouting under pressure and the closure in Geotechnical Engineering to soil nailing or anchor pole.
[background technology]
Carry out the air bag plugging device closure of grouting under pressure to soil nailing or anchor pole and slip casting effect is its application and promotes
Key, the slip casting to soil nailing or anchor pole at present is mainly realized by the method for Dumpage type, and general employing slip casting bag seals
Block up and improve grouting quality.But said method is unreliable because of plugging effect, it is impossible to substantial raising plugging effect and slip casting effect
Really.
[utility model content]
The purpose of this utility model is to improve the plugging effect in soil nailing or anchor pole aperture, improves the note to soil nailing or anchor pole
Slurry construction quality and effect, it is ensured that Foundation Pit Support Design purpose and cost-effective effect.
A kind of air bag plugging device carrying out grouting under pressure to soil nailing and anchor pole, it is characterised in that: this device is cylindric
Hollow shape, its crust is quality of rubber materials, and blast pipe jack, rubber bar jack and Grouting Pipe jack are left in inside, 3 jacks and
Being hollow between 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, then
Rubber bar is inserted in rubber bar jack, and blast pipe inserts blast pipe jack, and Grouting Pipe inserts Grouting Pipe jack；Afterwards air bag is sealed
Block apparatus is inflated expanding and contacts with the hole wall soil body, blocks soil nailing or anchor pole pore-forming aperture, is carried out by Grouting Pipe
Grouting under pressure, blast pipe is exhausted simultaneously.
By closure aperture after the inflation of air bag plugging device, being in close contact with the hole wall soil body, plugging effect is reliable, inflation behaviour
Make simplicity.
Carrying out grouting under pressure at the bottom of hole in hole, making grouting quality be improved, reaming increases aperture, improves withdrawal resistance, peace
Dress method is easy, the recyclable recycling of air bag plugging device.
Carry out grouting under pressure at the bottom of hole in soil nailing or bolthole, make the slurry of injection and pore-forming sidewall be in close contact.
After slurry solidification to be implanted, the gas discharge in air bag plugging device can be recycled and reused.
[brief description]
Fig. 1 is generalized section of the present utility model.
Fig. 2 is soil nailing rubber bar；Fig. 3 is anchor pole rubber bar.
In figure: the 1st, quality of rubber materials lid skin the 2nd, inflation inlet
3rd, blast pipe jack the 4th, quality of rubber materials crust
5th, rubber bar jack the 6th, Grouting Pipe jack
7th, quality of rubber materials endothelium the 8th, soil nailing rubber bar
9th, anchor pole rubber bar the 10th, reinforcing bar jack
11st, steel strand wires jack
[detailed description of the invention]
In conjunction with accompanying drawing 1, implementation process of the present utility model 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, air bag is by quality of rubber materials
The sulfuration of lid skin the 1st, quality of rubber materials crust the 4th, quality of rubber materials endothelium the 7th, inflation inlet 2 connects and composes, and whole balloon length is 500mm, directly
Footpath is 150mm.
It is respectively adopted soil nailing rubber bar the 8th, anchor pole rubber bar 9 according to air bag in the purposes difference of soil nailing or anchor pole to carry out
Being attached to rubber bar jack 5, rubber bar length is 500mm, a diameter of 50mm.By the reinforcing bar of respective model during soil nailing slip casting,
Inserting reinforcing bar jack 10, the diameter of reinforcing bar jack 10 is reserved according to bar diameter, by the steel strand wires of corresponding radical during bolt grouting
Inserting steel strand wires jack 11, the number of steel strand wires jack 11 is processed according to different-diameter and radical, and diameter is according to steel strand wires model
Reserved.Insert blast pipe respectively by blast pipe jack 3 and Grouting Pipe jack 6 and Grouting Pipe completes the peace of air bag plugging device
Dress.
Operation principle is: the air bag being completed is put into soil nailing or the aperture of anchor pole pore-forming, is inflated to inflation inlet 2
Closure aperture, 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 blast pipe, Grouting Pipe, rubber
Glue stick is in close contact.Carry out grouting under pressure at the bottom of hole by Grouting Pipe in soil nailing hole.Discharged by inflation inlet after slurry solidification
Gas in air bag, removes and reclaims air bag and rubber bar.
This air bag plugging device to soil nailing or anchor pole grouting under pressure, simple in construction, cheap, install and dismounting side
Just.Obtain reliable plugging effect by air bag plugging device, improve slip casting effect, integrated engineering is provided cost savings and makes
Valency.
