Description
Technical field
The present invention relates to control method during a kind of shield-tunneling construction, it is anti-that specially a kind of shield-tunneling construction supplements slip casting in real time
Subsidence control method belongs to civil engineering building technology applied technical field.
Background technique
Although Shield Construction Technique is greatly developed, ground settlement caused by constructing still can not avoid completely,
When carrying out shield-tunneling construction in city, the inevitably intensive section of penetrating ground complicated condition, top construction of structures, this is over the ground
The control of face sedimentation require it is just very high, when the control of shield crossing stratum settlement requires stringent material risk engineering or region, one
Kind method is to take soil stabilization, and the scheme that then shield is passed through again, this scheme requires ground to have enough reinforcing spaces,
When many situation shield crossing material risk engineerings and there is no the conditions reinforced in advance, and it is very high to reinforce cost in advance.The
Two methods fill shield tail gap by the method for synchronous note single slurry and subsequent auxiliary note dual slurry.Single slurries presetting period is long,
Initial setting strength is low, and it is closely knit to there is a problem of that arch crown part can not fill, that there are the degree of automation is low for subsequent after-teeming dual slurry,
Procedure connection hardly possible, easy plugging, and mix cement slurry in hole and cause the problems such as dust pollution is serious, and labor intensity of workers is big, to earth's surface
Settlement Control effect is also not satisfactory, therefore, Suporting structure self-condition is made full use of to carry out secondary grouting technological improvement to pass
It is important.
The cutterhead digging diameter of earth pressure balanced shield, EPBS is greater than shield shell outer diameter, and the diameter of tail shield is greater than the outer of section of jurisdiction
Diameter.Therefore after Shield Tunneling, exist between stratum and section of jurisdiction and excavate gap, due to shield own wt, excavate
The usual top in gap is larger, therefore, if the excavation gap at the top of shield does not fill in time during digging excavation, when passing through
The higher stratum of the sensibility such as flour sand, Extra-fine sand, and earth's surface deformation is induced when tunnel structure is closer apart from important risk source engineering
It is more than easily control standard, is difficult to control.Therefore, propose that a kind of shield-tunneling construction supplements slip casting anti-settling in real time regarding to the issue above
Control method.
Summary of the invention
The object of the invention is that providing a kind of shield-tunneling construction to solve the above-mentioned problems, to supplement slip casting in real time anti-settling
Control method drops.
The present invention is achieved through the following technical solutions above-mentioned purpose, and a kind of shield-tunneling construction supplements slip casting anti-settling control in real time
Method processed, comprising:

The top ball valve of the second endless tube piece be connected, waterglass slurry Grouting Pipe is connected with the slip casting ball valve of adjacent third endless tube piece, general
The liquid feeding end of main synchronous grouting pipe and secondary synchronous grouting pipe is connected to shield machine cement grout synchronous grouting case；
1.4 driving slip castings: shield machine starts to tunnel next ring, at the same open main synchronous grouting pipe, secondary tunneling synchronous mud injecting pump and
Waterglass starches Grouting Pipe, opens ball valve at the top of section of jurisdiction, at this point, the main synchronous grouting pipe of shield machine is synchronous to the first of abjection shield tail
Endless tube piece injects cement mortar, second endless tube piece top behind injection cement bonded sand of the secondary tunneling synchronous mud injecting pump to abjection shield tail behind
Slurry, waterglass starch the waterglass slurry mixed liquor in grouting pump extract water glass paste preparing bucket and starch Grouting Pipe to phase by waterglass
Injection waterglass slurry, two kinds of slurries mix behind in section of jurisdiction behind at the top of adjacent third endless tube piece, quick-hardening；
After 1.5 slip castings: closing ball valve, tear pulp feeding pipe open and cleaned, carry out subsequent construction repeatedly.
Preferably, to be that upper left, lower-left that shield machine carries are synchronous with three tunnel of upper right infuse the main synchronous grouting pipe in described 1.3
Slurry pipe；Secondary synchronous grouting pipe is the bottom right synchronous grouting pipe that shield machine carries.
Preferably, the proportion of the configuration waterglass slurry processes in described 1.2, waterglass and water is volume ratio 1:1.
Preferably, the slip casting process in described 1.4, setting time is 40s after the mixing of cement grout and waterglass slurries
Left and right control, slurries injection rate are controlled according to practical grouting pressure, and grouting pressure should be determined according to the Water And Earth Pressures at place, and one
As control within 5bar.
Preferably, the slip casting process in described 1.4, wherein the second endless tube piece includes two endless tube piece of D, B, third endless tube piece packet
Two endless tube piece of E, C is included, if this slip casting selection is two endless tube piece of D, E, slip casting next time selects two ring of B, C, so follows
Ring carries out.
The beneficial effects of the present invention are: this kind of construction method is effectively unified by synchronous grouting and second pulp feeding, by cementing
Slurry is organically combined with waterglass, enhances the timeliness and validity of section of jurisdiction behind gap filling, eliminates traditional secondary note
Slurry normally tunnels the interference that the two crossed construction generates with shield, and compared with traditional secondary grouting method, is not required to again individually
Cement grout is configured, only individually pumping waterglass slurries substantially reduce grouting amount, accelerate construction speed, make full use of shield
Structure machine equipment of itself improves the degree of automation, has saved manpower and material resources, has reached the good construction of effective control stratum settlement
Effect, it is easy to operate, effect is obvious, and normal shield-tunneling construction is not influenced, it can be effectively controlled stratum settlement.
