As a kind of optimal way: described the first annular double-layer air bag has connecting hole to be connected in the second air inlet pipe.
As a kind of optimal way: there is external screw thread at the outer wall place that the upper and lower two ends of main pipeline connect the first annular double-layer air bag and the second Ringlike double-layer air bag.
Utilize the present invention onethe adjustable annular double-layer air bag hole sealing device of kind carries out the method for sealing of hole, carries out according to following step:
Step 1, claimed in claim 1 oneplant adjustable annular double-layer air bag hole sealing device and put into drill hole inner wall, the first air inlet pipe and the second air inlet pipe are connected to compressed air outlet, and Grouting Pipe is connected to slip casting outlet;
Step 2, closes the second Ringlike double-layer airbag aeration to the first annular double-layer air bag by the first air inlet pipe and the second air inlet pipe, stops inflation when pressure reaches 0.5-0.8Mpa;
Step 3, forms airtight space slip casting by Grouting Pipe to two Ringlike double-layer pouches, drill hole inner wall and pipeline outer walls, stops slip casting when pressure reaches 1-10Mpa.
The beneficial effects of the utility model are: 1, simplify and manufacture, reduce original in the clip link of fixation balloon on pipeline respectively, realize Ringlike double-layer air bag by the internal pressure forming after Ringlike double-layer airbag aeration automatically fixing, thoroughly eliminated due to man-made assembly slip up the clip that causes while tying up the slip casting tightly not causing pouch come off or spillage, greatly promoted product quality; 2, make Ringlike double-layer air bag skin and drill hole inner wall mineralization pressure and Ringlike double-layer air bag internal layer and pipeline mineralization pressure by the internal pressure forming after Ringlike double-layer airbag aeration, make Ringlike double-layer air bag and drill hole inner wall, with the pipeline outer wall formation frictional force of spiral streakline, Ringlike double-layer air bag fixed, thereby realize job site adjusting to shutoff slip casting segment length in conjunction with boring geological condition, the scope of application is more wide in range, convenient; 3, production efficiency is improved, and labour intensity reduces greatly.

Detailed description of the invention
As shown in Figure 1, a kind of adjustable annular double-layer air bag hole sealing device, comprising:
Main pipeline: metal material or non-metallic material, be used for sealing empty rear slip casting, draining, the pump-line of connecting, specification is sealed the aperture of boring by design and is determined, generally length is that 3-15m(is easy to carry, when exceeding 6m, pipeline can be divided into two sections, when exceeding 9m, pipeline can be divided into three sections, middle by inside and outside silk (screw) connection), external diameter 50-100mm.In order to increase the frictional force between pipeline and annular air-pocket, use lathe, at it, long threaded line of annular air-pocket place processing 40-70 mm is installed, annular air-pocket place is installed generally apart from the each 1-3m of pipe ends place, specifically determine by design sealing of hole fragment position);
The first annular double-layer air bag and the second Ringlike double-layer air bag: annular air-pocket is to be made up of elastomeric material, length is 20-50cm, internal diameter is slightly less than pipe diameter, be generally 45mm-90mm, after inflation, have good dilatancy, the default copper pipe (air inlet port) with gingival cyst of mucous gland in the newborn mouth in outer end connects gas tube while preparing against inflation.The circular port that the first reserved diameter in annular double-layer air bag inner side is 16mm, for fixing Grouting Pipe;
The first air inlet pipe, the second air inlet pipe: the rubber tube that diameter is 16mm, the inflation end of the first air inlet pipe is installed the valve cock (market is on sale) with the connection air pump gas pipeline of one way valve;
Grouting Pipe: the rubber tube that diameter is 16mm, slip casting end is provided with one way valve;
The first annular double-layer air bag and the second Ringlike double-layer air bag are fixed on screwed pipe design slip casting section (determining by sealing of hole section design attitude); Described the first air inlet pipe is fixed on (one section of copper pipe that gingival cyst of mucous gland in the newborn button copper mouth is is 20mm built in the length with gingival cyst of mucous gland in the newborn mouth of the short portion of annular air-pocket in advance) on the first annular double-layer air bag gingival cyst of mucous gland in the newborn mouth copper mouth, the second described air inlet pipe is fixed between the first annular double-layer air bag and the second Ringlike double-layer air bag, described Grouting Pipe is fixed through preformed hole in the first annular double-layer air bag, and the outlet of Grouting Pipe is between two Ringlike double-layer air bags.
When use, compressed air piping is connected with the air inlet pipe of the first annular double-layer air bag, in two Ringlike double-layer air bags, be filled with compressed air, when reaching 0.5-0.8Mpa, pressure stops inflation, remove compressed air piping, then the pulp pipeline of Grouting Pipe and grouting pump is connected, with grouting pump to two Ringlike double-layer pouches and drill hole inner wall, pipeline outer wall forms airtight space slip casting, slurries are penetrated in rock (coal) by drill hole inner wall gap after filling this confined space, grouting pressure stops slip casting while reaching design grouting pressure (being generally 1-10Mpa), remove grouting pump Grouting Pipe, slurries solidify rear realization to the final shutoff of holing.
The adjustable annular double-layer air bag hole sealing device of the utility model, after being filled with air, Ringlike double-layer air bag forms certain intracapsular pressure, intracapsular pressure makes Ringlike double-layer air bag skin and drill hole inner wall mineralization pressure realize the shutoff to boring and annular air-pocket outer wall on the one hand, make on the other hand Ringlike double-layer air bag internal layer and pipeline mineralization pressure realize the shutoff of Ringlike double-layer air bag and pipeline outer wall, thereby make two Ringlike double-layer pouches and drill hole inner wall, pipeline outer wall forms airtight space, grouting pump is injected slurries in this confined space and by drill hole inner wall gap and is penetrated into rock (coal) by Grouting Pipe, slurries solidify rear realization to the final shutoff of holing.
