Sink and be bent, causes ground settlement, and this deformation is to continue to develop in a long time, if do not carried out to goaf
Processing, the engineerings such as building, water conservancy and traffic for building, which will be all deformed, even to be destroyed.With the continuous hair of economic society
Exhibition, influence of the mined-out area hazard problem to engineering construction is more prominent, and how to effectively control ground settlements to become important project
One of.Currently, being one of the effective ways for administering mined-out area hazard using Cement fly ash filling is carried out to goaf.
During slip casting, traditional Grouting Pipe structure does not have plugging structure, will cause slurries and largely flows out from drilling, makes
At waste；In addition, conventionally employed Grouting Pipe structure stops due to slip casting, it is possible to create overfall causes the waste of slurries.
Currently, can all encounter only slurry overfall problem, existing stop grouting plug when carrying out injecting treatment to goaf and generally be set with
It is put into togerther in the drilling being drilled in Grouting Pipe with Grouting Pipe, in actual use, often occurs during the installation process, only starching
Phenomena such as cock body abrasion, deformation cause to destroy, can not irregularly tamp gap because of hole inner diameter size, slurry seal can not be continued, led
It causes to block not tight, the slurry reflux in drilling, seriously affects and only starch effect and filling regulation effect, and more existing pass through
The stop grouting plug that closure is filled to drilling is expanded, dilation needs singly to connect Grouting Pipe and carries out slip casting, uses very not
Just, construction speed is influenced.In addition, due to during slip casting slurry pressure it is excessive, make stop grouting plug fail example also can be found everywhere,
