Description
Technical field
The invention belongs to Goaf Area Treatment process fields, and in particular to one kind is for filling underwater deep confined space
Assembled storage slurry device and its assembly method.
Background technique
Goaf refers to subterranean resource is produced after the exploitation space that is formed of underground, according to exploitation mineral and mining method
Difference, goaf top plate show different failure modes, therefore earth's surface also generates different deformation behaviours.Such as it is directed to and adopts
When being exploited with complete sunken method, the top plate of ore body can be constantly caving with the expansion of productive area, to collapse in earth's surface formation
Basin is fallen into, the destruction of earth's surface is to follow hard on the exploitation of ore body and occur；And when being directed to non-entirely sunken method (house column type) and being exploited,
The top plate of ore body is relatively stable, and when ore pillar is stablized, ground will not collapse, and with the expansion of production zone (mining height),
The effects of infiltration of underground water, ore pillar weathering, after ore pillar unstability, top plate can occur to collapse suddenly, so as to cause the prominent of ground
So collapse.
When in area of influence of extraction to carry out construction activity, need first to administer the goaf under it.Root
There is different administration ways according to goaf depth, the difference of working thickness, when being directed to the goaf that productive area is big, depth is big
When being administered, grouting filling is the main means for administering goaf.
Technical comparing of the home and abroad in terms of filling improvement is mature at present, and according to the different situations in different mines
Have developed many advanced filling Treatment process, in goaf harnessing field, according to the mobility of slurries can be divided into dilute slurry with
Thick slurry liquid, wherein for dilute slurry mainly with flyash, cement composition, injecting paste material partial size is smaller, is equal in slurries transmission process
Mass flow is suitable for administering the lesser region in cavity；Thick slurry liquid is mainly by mine tailings, sand, rubble, cement composition, injecting paste material
Grain diameter it is larger, be heterogeneous flow in slurries transmission process, be suitable for administering the biggish region in cavity.
It is directed to the improvement of Goaf Area at present, is to be conveyed by pipeline, during transportation by gravity
Slurries are transported in goaf by potential energy and pumping kinetic energy.Slurries are water-less environment during transportation, could only in this way be protected
The property of card slurries does not change during transportation.This just greatly limits the treatment range in goaf.
When having water in goaf and slurries conveying distance is longer, water can generate extreme influence to slurries property, for dilute
Slurries, such as the slurries being made of fine graineds such as cement, flyash, participating in for water can dilute original concentration of slurry significantly, drop
Low calculus rate and consolidating strength, influence slip casting effect；For thick slurry liquid, such as concrete, mortar, participating in for water can make slurries
Isolation causes slurries that can not be sent into region to be administered, for ointment material, water can cause slurries directly to disperse so as to cause plugging
And lose mobility.
Therefore, when having underground water for filling in goaf, how the slurries being stirred are delivered to mined out region is
Urgent problem to be solved.
Summary of the invention
One embodiment of the invention provides a kind of assembled for filling underwater deep confined space and stores up slurry device and its assembly
Method, for solving problem of the prior art, comprising:
In one embodiment, a kind of assembled storage slurry device for filling underwater deep confined space is provided, including multiple
Device unit is starched in the storage of head and the tail connection,
Device unit is starched in each storage respectively include:
One tube body has a cavity axially communicated；
Two plug components, are respectively arranged at the both ends of cavity, and each plug component is respectively to close or unidirectionally
Open one end of the cavity.
In one embodiment, a kind of assembly side of assembled storage slurry device for filling underwater deep confined space is provided
Method, comprising:
S1, in above goaf construction drill, as slip casting channel；
S2, storage slurry device unit bottom end seal plug plug is set, slurry is injected into cavity, by plug plug by cavity top
End sealing；
It is sequentially connected up and down between s3, storage slurry device unit；
S4, the storage slurry device of connection is sent into slip casting channel；
S5, Grouting Pipe is connected to the top of storage slurry device, slurries will have been configured and poured into, by plug under grouting pressure effect
Plug is washed open and realizes continuous grouting.
Compared with prior art, the beneficial effects of the present invention are:
1, slurries transportation problem in an underwater environment is solved, when having water in goaf and slurries conveying distance is longer
When, water can generate extreme influence to slurries property, and participating in for water can dilute original concentration of slurry significantly, reduce calculus rate and knot
Stone body intensity results even in slurries and isolates, is disintegrated so as to cause plugging during transportation, causes slurries that can not be sent into wait control
Manage region.The present invention is by the filling independent assembled storage slurry device in ground, then each assembled is stored up slurry device and is joined end to end tripping in
In hole, contact of the slurries with water has effectively been obstructed, has solved the problems, such as that slurries can not convey in an underwater environment.
2, during solving vertical long-distance transportation, the diseases such as isolation that slurries occur, and then cause plugging slurries without
The problems such as method conveys.This assembled storage slurry device is relatively independent unit, and 3 meters of each unit or so, during installing, each unit
Interior slurries belong to static condition, and the slurries that effective solution slurries occur during vertical long-distance transportation are rotten to ask
Topic.
3, before slip casting, usually it need to determine whether need tripping in steel pipe to be protected in drilling according to the integrated degree of hole wall,
To guard against when borehole wall crack is more developed, slip casting easily causes hole wall chip off-falling and then causes plug-hole accident in hole, meanwhile, slurries
It will increase the discharge pressure of slurries with the friction of hole wall, reduce construction efficiency.The present invention stores up slurry device as slurries by assembled
Storage transport channel so that slurries assembled store up slurry device in circulate, reduce the unstable influence to slip casting of hole wall outside, have
The pipe resistance of effect reduced in slurries transmission process, further improves slip casting efficiency.
4, the slurries filling of underwater confined space is solved the problems, such as, in closed underwater goaf space, due to underground sky
Between water-saturated state, during slip casting, pressure is larger in goaf, frequently can lead to the case where slurries can not inject, this work
Method effectively reduces grouting pressure by vent of constructing, and solves the problems, such as that slurries can not inject underwater confined space, together
When vent be alternatively arranged as detection, supplement injected hole use, further improve mortar depositing construction quality.
