The purpose of the present invention is directed to existing conventional slurry injection technique of sleeve valve tube deficiency in actual applications, play the sealing function that layered seal replaces the sheath body bed of material using inflation is bicyclic, the sheath body bed of material of mini-valve tube appearance is wrapped in so as to cancel, there is provided one kind is without sheath body bed of material sleeve valve barrel grouting rapid constructing method.
Technical scheme is specific as follows：
One kind is without sheath body bed of material sleeve valve barrel grouting rapid constructing method, including step：
1）Mud off vertical drilling is carried out in foundation soil using geological drilling rig, injected hole is obtained；
2）Upper inflation ring and lower inflation ring are from top to bottom enclosed within mini-valve tube outer surface, upper inflation ring and lower inflation ring connect a wireway respectively；
3）Inflation ring and lower inflation ring position in adjustment, lower inflation ring is adjusted to from the position of mini-valve tube bottom 0.5m ~ 1.0m, and the distance between upper inflation ring and lower inflation ring are ground floor stratum slip casting thickness；
4）The mini-valve tube of bottom end closure is inserted in the brill injected hole together with upper inflation ring and lower inflation ring, until mini-valve tube bottom reaches injected hole bottom；
5）Upper inflation ring and lower inflation ring are inflated respectively by wireway on ground, inflation ring and lower inflation ring inner side is set to be close to mini-valve tube outer surface, slip casting hole wall is close in outside, so as to form the slip casting gap of closing between mini-valve tube outer surface and slip casting hole wall and upper inflation ring and lower inflation ring；
6）The grouting tube with upper and lower stop grouting plug is inserted into mini-valve tube, distance between upper and lower stop grouting plug is adjusted, the slip casting of ground floor stratum is carried out by Grouting Pipe；
7）After completing ground floor stratum slip casting, the gas in inflation ring is drained, and the position of upper inflation ring is lifted up along mini-valve tube, range of lift is second layer stratum slip casting thickness；
8）Upper inflation ring is inflated, then corresponding lifting sleeve floral tube and upper and lower stop grouting plug carry out the slip casting of second layer stratum；
9）Repeat step 7）~8）, until completing the slip casting operation of whole injected hole；
10）Before injection slurry condenses completely, mini-valve tube is extracted, once purged reuse；
11）Recharge slurries in the hole that mini-valve tube leaves are being extracted, until filling.
Further, step 5）In, the blowing pressure of the upper inflation ring and lower inflation ring is 2 ~ 20 atmospheric pressure.
Further, the upper inflation ring and lower inflation ring are made up of rubber or earth working material.
Compared to existing technology, the present invention not only has all advantages of conventional sleeve valve barrel grouting, and overcomes the main deficiency of conventional sleeve valve barrel grouting, and its advantage is：
（1）Using the bicyclic sealing function for playing the layered seal substitution sheath body bed of material is inflated, cancel the sheath body bed of material, reduce material consumption, and the time saved needed for reaching some strength because of the solidification of the sheath body bed of material, substantially increase speed of application；
（2）Mini-valve tube can extract reuse, it is to avoid consumption tube material；
（3）Due to eliminating the sheath body bed of material, slurries can uniformly fill the gap between mini-valve tube and slip casting hole wall, uniformly be spread in Rock And Soil, it is to avoid injecting cement paste non-continuous event caused by being difficult to control because of slip casting diffusion, hence it is evident that improve slip casting effect；
（4）By adjusting the distance between upper and lower inflation ring, the lift height of slip casting can be adjusted according to stratum actual conditions；
（5）It is reusable due to cancelling the sheath body bed of material and sleeve valve steel pipe, significantly reduce construction cost.
