Description
Technical field
The present invention relates to a kind of deep water conditions setting of casings to orient the method that laying is reinforced and gushing water band blocks.
Background technique
Dawenkou mine occurs large-scale gushing water, causes to flood well accident during shaft excavation.Through analyzing: for lateral development
Plane Rock Bed_Seperated Zone be connected caused by surface water with the major fault longitudinally developed nearby.It needs to carry out front pre-grouting to working face,
Since water is big (3860m3/h), draining is difficult.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of orientation laying of deep water conditions setting of casing and reinforces and gushing water
With the method blocked, the technical scheme is that the side that the orientation laying of deep water conditions setting of casing is reinforced and gushing water band blocks
Method, comprising the following steps:
(1) positioning assembling is carried out to casing；

(3) overall package of casing and grouting pipeline forms combined platform；
(4) combined platform general safety is sent into the underwater designated position 160m, finally carries out casing reinforcement again and blocks gushing water band.
The step (1) specifically: according to the size requirement of shaft in wall, preset the six roots of sensation along shaft in wall circumferencial direction
Casing, six roots of sensation casing are welded on platform skeleton, and the diameter of each casing is 108mm, all casings from circumference centroclinal dip,
With pit shaft axis 5o angle, the top of each casing installs slide valve, is equipped with cover board on the slide valve.
The step (2) is that welding tree root shape radiates grouting pipeline, and slip casting supervisor is centrally located, in slip casting master
The peripheral solder of pipe has several radial slip casting branch pipes, and each slip casting branch pipe is connected to slip casting supervisor, slip casting branch
Slurry outlet is offered on pipe, the length of the slip casting branch pipe on same plane is different.
The step (3) is that the middle part being welded on platform skeleton is responsible in slip casting, and six roots of sensation casing is responsible for along slip casting
Periphery is uniformly distributed, and shorter slip casting branch pipe is directed toward casing, and longer slip casting branch pipe is directed toward the borehole wall, and each slip casting branch pipe has a down dip
Tiltedly.
The step (4) are as follows: under the casing welded together by grouting pipeline and with grouting pipeline with stable car is slow
It puts, in decentralization process, adjusts the equilibrium state for the combined platform that grouting pipeline and casing are formed in time；Combined platform is in place
Afterwards, rubble is launched at the fine sand layer of lower part laying 20-30cm thickness, middle part, the fine sand layer of top laying 20-30cm thickness again,
Then slip casting is carried out.
Disturbance layer gap should be filled in slip casting, again pack portion Rock Bed_Seperated Zone and crack, while being also contemplated that single
Line number of dropouts；Specifically: clear water is initially injected before slip casting, clear water injects flow 250L/min, injection rate 10-12.5m3, so
It is implanted sequentially the water glass solution 3-5m3 of 22 Baume degrees again afterwards, reinjects 50% alkaline chlorine dioxide solution of 3-5m3；Then it carries out normal
Slip casting, slurries are single liquid cement grout, the mass ratio of the ratio of mud, that is, water and cement using 1.5:1,1.25:1,1:1,0.75:1,
The cement grout of 0.6:1, when injection, by wish it is dense be implanted sequentially, after slip casting, on top, the upper surface of fine sand layer is thrown again spreads one
Isolated protective layer is formed after layer saltcake protective agent；It is V, V=V1+V2, V with reference to slurries injection rate1=1\4πd2η H λ, V2=λπ(D/2+
R)2Hηβ/m；D- pit shaft net diameter m, η-rock fracture rate 0.5%-3%, H- slip casting section height-m-, λ-slurries loss coefficient 1.2-
1.5, D- pit shaft famine diameter m, R- grout spreading range m, β-slurries effective volumetric efficiency 0.9 in crack, m- slurries calculus rate
0.85；Wherein, synchronous draining in time is needed during slip casting, keeps the dynamic equilibrium of raw water position；It is tight according to grouting serous fluid flow
Lattice control displacement, i.e., being pumped into slurries amount to shaft bottom is 250L/min, synchronous out of pit shaft to extract same water out, purpose in order to
Reach dynamic equilibrium；Slip casting terminates to be drained after a week.
The invention has the advantages that on earth, measuring the total water leakage of pit shaft is 2.1 m for pit shaft draining after a week3/ h, it is main former
Shaft wall leak point, water sealing effect 99.9% are with the naked eye seen and have confiscated obvious EXIT POINT.Casing surveys pressure 5.0Mpa, water sealing effect and resistance to
Pressure value reaches design requirement, gives slip casting work for further work face and has established successful basis.
