Description
Technical field
The present invention relates to a kind of portable slip casting casing bits for being applicable to grouting behind shaft or drift lining, and in particular to one kind is suitable for
The portable slip casting casing bit and application method of grouting behind shaft or drift lining.
Background technique
Nowadays, it is just propped up in Tunnel, percolating water, operation phase Tunnel Water Leakage etc. after two lining percolating waters, subway station wall
Engineering project disaster happens occasionally, especially along with the development of urban track traffic.Slip casting is as reinforcing weak broken wall rock and envelope
The mode of the effective means of stifled underground water, grouting behind shaft or drift lining is widely used in the work of underground engineering water blockoff, and such as
The problems of modern most of grouting behind shaft or drift lining work carried out are as follows:
One, only slurry effect is poor, easily generation nozzle running pulp accident, and retention ratio of the slurries in effective coverage is lower, greatly
Ground causes the waste of material；
Two, when grouting pressure is excessive, when often resulting in collapsing out for Grouting Pipe, and implementing the slip casting of vault vertical hole, Grouting Pipe
The placement on road is more difficult；
Three, after slip casting, prominent end need to be cut off using cutting machine, and construction in later period wall surface restores difficult, increase manpower
Material resources improve cost, influence the duration.
Therefore, a kind of portable slip casting casing bit suitable for grouting behind shaft or drift lining how is designed, this has Practical Project
Important meaning.
Summary of the invention
It the purpose of the invention is to overcome the shortcomings of existing grouting device, provides a kind of easy to operate, can further mention
The slip casting casing bit and application method of high efficiency.
To achieve the above object, the present invention adopts the following technical solutions:
