The present invention is that technical solution problem adopts following technical scheme:
In shield machine cabin of the present invention, the feature of solidifying of the working face structure is: arranging one reinforcing wall as solidifying of the working face structure along shield machine front face.
Described reinforcing wall is thickness is 0.1-0.2m, area is 40-45m
2cement mortar body of wall.
In shield machine cabin of the present invention, the feature of the construction method of solidifying of the working face structure is that following steps are carried out:
A, outfit grouting mortar, empty shield machine soil cabin, continues next-step operation when shield machine soil cabin soil pressure remains zero;
B, synchronous grouting pipeline is connected to shield machine soil bulkhead preformed hole, in shield machine soil cabin, injects mortar by synchronous grouting pipeline, until mortar fills shield machine soil cabin and forms mortar body of wall at face place, shield machine front;
C, pre-grouting steel pipe to be inserted in shield machine pre-grouting hole, to make described pre-grouting pipe stretch into above the face of shield machine front; Utilize secondary injection pulp grinder to inject cement slurry by pre-grouting steel pipe, reach after setting value until grouting pressure, shrink the hinged shield machine that makes of shield machine and retreat, form reinforcing wall;
D, when the mortar injected and cement slurry reach initial set state, empty the mortar in shield machine soil cabin and cement slurry, when the reinforcing wall formed by the mortar injected and cement slurry completes initial set, operating personnel can open the cabin tool changing.
In shield machine cabin of the present invention, the feature of the construction method of facies palmaris ruggedized construction is also:
The batching of described mortar is: cement 300-350kg, flyash 320kg, swell soil 200kg, sand 770kg, water 570kg;
Described cement slurry proportioning is by weight: water: cement=0.8: 1.
In shield machine cabin of the present invention, the feature of the shield machine modified node method of solidifying of the working face construction connects synchronous grouting pipeline in described shield machine soil bulkhead preformed hole, pre-grouting steel pipe is inserted in described shield machine pre-grouting hole, described pre-grouting steel pipe is arranged for lengthening, and the front end of described pre-grouting steel pipe can be stretched into above the face of shield machine front.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention makes shield machine front face soil stabilization intensity high, after hatch door is opened, can place ice cube, arranges ventilation etc. in cabin, personnel can in cabin long working, drastically increase tool changing operating efficiency;
2, the present invention is not by construction plant environmental constraints, the less investments such as its manpower, financial resources, thing force-summing device;
3, through repeatedly using this method to open the cabin tool changing, ground monitoring measures sedimentation hardly;
4, can effective guarantee underdeck operation personal security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Number in the figure: 1 shield machine; 2 pre-grouting steel pipes; 3 shield machines are hinged; 4 pre-grouting holes; 5 synchronous grouting pipelines; 6 native bulkhead preformed holes; 7 reinforcing walls.
Detailed description of the invention
See Fig. 1, in the present embodiment, in shield machine cabin, solidifying of the working face structure is arranging one reinforcing wall 7 as solidifying of the working face structure along shield machine front face, and reinforcing wall 7 is thickness is 0.1-0.2m, area is 40-45m
2cement mortar body of wall.
The shield machine modified node method of constructing for solidifying of the working face in shield machine cabin in the present embodiment connects synchronous grouting pipeline 5 in the native bulkhead preformed hole 6 of shield machine, pre-grouting steel pipe 2 is inserted in shield machine pre-grouting hole 4, pre-grouting steel pipe 2 is arranged for lengthening, and the front end of pre-grouting steel pipe 2 can be stretched into above the face of shield machine front.
