Description
Technical field
The utility model is related to shield-tunneling construction field, more particularly to applied to shield back synchronous injection or secondary
Mend the micro-destabilization slip-casting device in slurry construction.
Background technology
During shield-tunneling construction, after the completion of shield cutter is excavated, duct piece assembling machine carries out the assembly of section of jurisdiction, due to cutterhead
Digging diameter is slightly larger than the external diameter of section of jurisdiction, causes country rock body annular gap together with being formed between section of jurisdiction, if not by this gap
Filling in time, then the country rock body around section of jurisdiction, which will loosen, even caves in, so as to cause the adverse consequences such as ground settlement.For
This, it is necessary to the annular gap between country rock body and section of jurisdiction is filled into closely knit, the synchronous grouting in time using synchronous grouting means
Means are that injected hole is set on section of jurisdiction, by shield grouting behind shaft or drift lining device toward injected hole while section of jurisdiction departs from shield machine
Slip casting is carried out, by the annular gap between slurries simultaneous implantation country rock body and section of jurisdiction, to prevent ground settlement.Current shield
Grouting behind shaft or drift lining device has following technical problem：1st, slip casting starting stage slurry flow is big, and slip casting direction is just to country rock body, just
Face impact is strong, and larger disturbance can be caused to stratum, disturbs excessive there is a possibility that stratum settlement, or even can seriously injure ground
The safety of pipeline, important building；2nd, the slip casting later stage easily blocks injected hole, when particularly injecting dual slurry.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provide it is a kind of it is small to ground disturbance, be not easily blocked injected hole
Shield wall after micro-destabilization slip-casting device.
In order to realize the purpose of this utility model, the technical scheme used for：Micro-destabilization slip-casting is filled after a kind of shield wall
Put, including the blender and casting head set gradually, it is characterised in that：Grout outlet, the pulp are connected with the casting head
The top of pipe is connected with guide head by check valve, and the side of the guide head is provided with least one slurry outlet.
As further improvement of the utility model, the slurry outlet is provided with two, is symmetrically arranged at guide head
Side on.
As further improvement of the utility model, the slurry outlet is the square aperture being located on guide head.
As further improvement of the utility model, the top of the guide head is cone.
As further improvement of the utility model, ball valve is connected between the blender and casting head.
It is to be threadedly coupled as further improvement of the utility model, between the blender, casting head and ball valve.
As further improvement of the utility model, the blender is provided with waterglass joint and filling adaptor.
As further improvement of the utility model, pressure gauge is connected with the pipeline of the waterglass joint.
As further improvement of the utility model, the filling adaptor is the snap joint for being located at blender tail end.
The beneficial effects of the utility model are：The utility model is being noted by the setting of grout outlet, check valve and guide head
During slurry, guide head is directly extended in the annular gap between country rock body and section of jurisdiction, makes slurries by the slurry outlet of guide head side
From the side diffusion of guide head, the annular gap is filled.Due to the utility model by guide head toward slip casting is carried out sideways, not directly
Impact country rock body is connect, so as to realize micro-destabilization slip-casting；Because guide head is directly protruding into country rock gap, it is full that slurries are more easy to filling
It is full, and it is not easily blocked injected hole；Check valve can prevent slurry reflux.The utility model is simple in construction, beneficial to implementation, can be from basic
The upper present situation for changing the construction of current shield grouting, reduces the heavy of the ground as caused by shield-tunneling construction and the important construction of structures of earth's surface
Drop, it is ensured that the safety of people's lives and properties.
