Description
Technical field
The present invention relates to tunneling shield technical field of construction, more particularly to a kind of shield-tunneling construction huge stone handling construction method.
Background technology
At present, the construction of the engineerings such as urban subway tunnel, road and rail tunnel, water conservancy water-conveyance tunnel is carried out using shield machine
Deng more and more universal, it has the advantages that automaticity is high, speed of application is fast, quality is good, safe.Wherein, soil pressure is put down
Weighing apparatus formula shield machine is wider to the adaptability on stratum, is to apply a kind of more type, its operation principle is the knife using shield machine
Disk cuts the soil body or rock mass, with the propulsion of shield machine, and the soil that knife cutting gets off enters in the native storehouse of shield machine, passes through spiral transferring
The control of the casting such as machine and its casting valve mechanism is sent, matching for soil discharge quantity and shield driving amount is realized, shield driving is formed
Keep excavating the stable dynamic equilibrium of face simultaneously, Shield Construction Method Used is smooth.
However, when granitic formation carries out constructing tunnel using shield machine, being frequently encountered " boulder ", (granite is spherical
Waste) cause shield machine driving difficult, it is impossible to normal construction.Granite onion weathering thing is a kind of common weathering phenomenon,
It is in residual soil and weathered rock formation, because being influenceed the weathering to be formed is uneven to remain by the arrangement of mineral anisotropy and fractured zones
Body, due to weathering ball surrounding rock mass, with onion weathering rock mass there is larger gap in intensity itself, often there is soft or hard uneven ground
Matter phenomenon, this just easily causes tool damage, results even in cutterhead deformation, causes whole shield machine to be paralysed.
At present, in granitic formation tunneling shield tunneling process, the method for disposal of boulder is run into substantially：Verifying shield
In front of structure after " boulder " distributing position and size, according to live periphery human settlement, geology and geomorphology, underground utilities move towards situation,
The methods such as surface drilling explosion, punching are broken, manually digging hole is abolished are taken to abolish boulder.
The content of the invention
The technical problems to be solved by the invention are to provide the shield-tunneling construction huge stone handling that a kind of efficiency of construction is high, cost is low
Construction method.
To solve the technical scheme that above-mentioned technical problem is used：A kind of shield-tunneling construction huge stone handling construction method, including
Following steps：
S1, basis verify size, the position of the residing underground space of obstacle boulder, determine the orientation of Construction of Silo；
S2, progress Construction of Silo reach predetermined well depth, and the steel pile casting that diameter is less than vertical shaft aperture is laid in vertical shaft；
Former slurry coat method in S3, pump drainage steel pile casting, meanwhile, to injection paste mud between steel pile casting and vertical shaft inwall；
S4, the size according to obstacle boulder, the position of the residing underground space, laterally construction is formed positioned at obstacle boulder in vertical shaft
The hole in place of lower section, hole in place is formed by the high pressure jer cutting soil body and discharges cutting dregs through vertical shaft, until
Place hole is spreaded manuer in holes work completion, and obstacle boulder dropped down onto in hole in place；
S5, to slip casting at original obstacle boulder position and vertical shaft is filled, the steel pile casting in removal shaft.
Beneficial effect：In this shield-tunneling construction huge stone handling construction method, abandoning tradition is abolished by force to obstacle boulder
Mode, excavates the hole in place that space is slightly larger than obstacle boulder volume below obstacle boulder by construction shaft, passes through shield
The gravity guiding obstacle boulder of machine or obstacle boulder in itself is moved in the hole in place outside tunnel cross-section, shield machine is set in original
Passed through on meter tunnel axis, obstacle huge stone handling is simple and quick, cost is low, short construction period.
Brief description of the drawings
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
A kind of reference picture 1, shield-tunneling construction huge stone handling construction method of the invention, comprises the following steps：
S1, size, the position of the residing underground space for verifying using drilling machine obstacle boulder 1, to determine to excavate the lonely stone of obstacle
The position and the space of required excavation in hole 2 in place, it is ensured that do not hinder the normal pick of follow-up shield machine after obstacle boulder dropping place
Enter；
S2, using Big Diameter Hole Drills earth's surface through designed appropriate location drilling carry out vertical shaft 3 construct, boring procedure uses mud
Starch retaining wall pore-forming；
S3, the construction of vertical shaft 3 are reached after design well depth, insert the steel pile casting 4 for being slightly less than the inwall aperture of vertical shaft 3 with well depth equal length,
The cat ladder 5 that vertical shaft 3 is passed in and out for staff is welded with steel pile casting 4；
S4, using former slurry coat method in slush pump pump drainage steel pile casting 4, meanwhile, inject cream between steel pile casting 4 and the inwall of vertical shaft 3
Shape mud 6；
After mud is cleaned out in S5, steel pile casting 4, workmen enter vertical shaft 3, by obstacle boulder 1 hole in place 2 it is relevant
Parameter, sets up an operation platform below the elevation location in the horizontal hole 7 of processing boulder, carries out the processing horizontal hole 7 of boulder and in place
The construction in hole 2；
S6, hole in place 2 carry out cutting excavation using high-pressure water jet, and the high process control in the bottom of hole 2 in place and the horizontal bottom of hole 7 of boulder are high
Cheng Xiangtong, the dregs that high pressure jer cutting is excavated is flowed into vertical shaft 3 by the horizontal hole 7 of boulder, and uses slush pump by cutting
Outside dregs discharge vertical shaft 3, excavated by the lasting cutting of high-pressure water jet, dregs is constantly discharged outside vertical shaft, until hole is applied
Work is completed, obstacle boulder dropping place；
S7, when determining that obstacle boulder 1 is had moved into outside shield tunnel section, to original obstacle boulder position at slip casting and fill
Steel pile casting 4 in vertical shaft 3, removal shaft 3, recovers original place looks.
The hole in place 2 that space is slightly larger than obstacle boulder volume is excavated below obstacle boulder 1 by construction shaft, passed through
The gravity guiding obstacle boulder 1 of shield machine or obstacle boulder 1 itself is moved in the hole in place 2 outside tunnel cross-section, makes shield
Machine is passed through on original design tunnel axis, obstacle boulder 1 is not abolished, to save substantial amounts of human and material resources, wealth
Power and the duration for shortening processing boulder.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the knowledge that the technical field those of ordinary skill possesses
Put that various changes can be made.
