Description
Technical field
This disclosure relates to underground engineering grouting and reinforcing antiseepage field, and in particular to a kind of protrusive bores note integrated device and makes
Use method.
Background technique
In the geotechnical engineering of the undergrounds such as subway, tunnel, foundation pit, rich water soft stratum is frequently encountered, if without effectively locating
Reason often will lead to the disasters such as landslide, prominent water burst, and slip casting is to reinforce soft stratum, blocks the effective ways of underground water.
Segmenting slip casting compares common slip casting, has range of scatter more uniform, the more preferable advantage of slip casting effect.Drilling rod retreats
Segmented slip casting and protrusive segmenting slip casting are currently used two kinds of segmenting slip casting methods.Drilling rod retrusive grouting method is to adopt
With drilling rod disposal pore-forming, drilling rod is retreated using drilling rod directly as Grouting Pipe and realizes segmenting slip casting, but the grouting method exists
Lack effective quarantine measures between different slip casting sections, cause slip casting controllability limited, it cannot be guaranteed that all slurries enter mesh
Mark slurry section.Therefore, to solve the problems, such as that different slip casting sections are difficult to be isolated, protrusive is mostly used to be segmented in practical Grouting engineering
Lower Grouting Pipe slip casting, is drilled into Grouting Pipe slip casting under next slip casting Duan Houzai again, sets until reaching after the drilling of grouting mode, i.e. first section
Count depth.And rich water soft stratum grouting and reinforcing and water blockoff focus on quickly in time, drilling rod retrusive grouting mode need to drill to setting
Depth is counted, drilling time is long, and easily forms conduit pipe, and then causes prominent discharge disaster, and protrusive segmenting slip casting mode needs
It is inserted into Grouting Pipe after drilling and carries out slip casting, multiple operating processes delay the slip casting time and easily lead to safety accident, and because
Stratum is weak, deposits collapse hole Grouting Pipe after piercing and is not easy the problem of being inserted into.
Summary of the invention
The purpose of disclosure is to overcome above-mentioned the deficiencies in the prior art, to provide a kind of protrusive and bore note integrated device and use
Method；The device can realize that protrusive bores note integrated construction, greatly saving workload in rich water soft stratum, and have

Stop drilling, drilling rod retreats set distance, stops the intracapsular water filling of pulp-water to expansion type, so that expansion type is stopped the expansion of pulp-water capsule and squeezes
Drilling；
The slip casting into hole from inner tube, from inner tube to hole internal pressure water after the completion of slip casting；
Removal expansion type stops the hydraulic pressure of pulp-water capsule；
Above step is repeated, next slip casting section drilling and mortar depositing construction are carried out, until reaching setting bored grouting depth.
9. application method as claimed in claim 8, characterized in that the water injection pressure that expansion type stops pulp-water capsule is greater than slip casting pressure
Power.
10. application method as claimed in claim 8, characterized in that pressure water water is equal to current slip casting section drilling volume.
