The water-permeable brick is prepared from the dolomite dead rock generated after mining and the cement, the water-permeable brick is used for laying of the mine down-hole filling retaining wall, and the filling retaining wall has high strength, good water permeability and low pulp permeability, and is low in cost, easy to manufacture and convenient to construct.
Description
Technical field
The invention belongs to mine down-hole goaf filling technical field, it is specifically related to one kind for mine down-hole filling gear
The water-permeable brick of wall and its building method.
Background technology
Underground goaf filling counterfort Main Function is to intercept goaf filling slip to overflow, and has good infiltration work(
Effect, so that cemented fill quick-hardening, reaches the purpose supporting goaf top plate.Therefore, filling counterfort building materials should be expired
Foot basic demand be：(1) there is higher intensity, meet the lateral pressure to barricade for the slip after filling；(2) have preferably permeable
Property, to reduce secondary filling interval time, improve pack effectiveness；(3) have relatively low ooze slurry, filling slurry can be stoped to overflow,
Improve filling quality；(4) low price, easy construction, meet the execution conditions that down-hole barricade is built by laying bricks or stones.
At present, mine applies filter pipe to carry out goaf filling slurry dewatering mostly, and filling counterfort building materials itself
Do not possess dehydrating function, and filter pipe sets up trouble, there is potential safety hazard.Though some filling counterfort building materials possess dehydration work(
Can, but can not effectively stop filling slurry from overflowing, filling quality is poor, and price is costly.Therefore how to build by laying bricks or stones good water permeability,
Ooze that slurry property is low, intensity is high, speed of application is fast and the barricade of low cost, the effectively shortening cementing setting time of filling slurry, raising is filled
Fill out efficiency and quality, be the emphasis that mine is studied always.Meanwhile, create a large amount of barren rocks during mining, store up for a long time
In earth's surface, do not only take up tract, destroy ecological environment, and easily induction geology and engineering project disaster, bring to mining production
Serious safety and environmental protection hidden danger.
Content of the invention
The invention reside in for existing filling counterfort building materials bad hydraulic permeability, oozing slurry property height, low intensity, expensive etc.
Not enough, there is provided a kind of water-permeable brick for mine down-hole filling counterfort and its building method.
The present invention is achieved by the following technical programs.
A kind of water-permeable brick for mine down-hole filling counterfort, including water-permeable brick body, described water-permeable brick body is every pulp layer
And the pervious bed being connected with every pulp layer, described pervious bed is internally provided with discharge orifice, and discharge orifice by every pulp layer to dipping down outward
Tiltedly, described form by dolomite and the blended solidification of cement every pulp layer and pervious bed, and the mass ratio of dolomite and cement is
9:1～11:1.
The described thickness every pulp layer accounts for the 1/3～1/5 of water-permeable brick body gross thickness.
Described dolomite particle diameter in pulp layer is 2～3mm.
The thickness of described pervious bed accounts for the 2/3～4/5 of water-permeable brick body gross thickness.
Dolomite particle diameter in described pervious bed is 3～6mm.
Described discharge orifice runs through two side surfaces of pervious bed, and downward-sloping angle is 10 °～30 °.
The aperture of described discharge orifice is 5～10cm.
A kind of method using above-mentioned permeable brick masonry mine down-hole filling counterfort, its concrete grammar step is as follows：
(1) demarcate filling counterfort and build position by laying bricks or stones：Field survey unwrapping wire is carried out according to design requirement, demarcates filling counterfort concrete
Build position by laying bricks or stones；
(2) build forward position calibration position by laying bricks or stones and excavate foundation trench to hardcore；
(3) lay concrete：Hardcore described in step (2) lays the concrete that a layer thickness is 0.3～0.5m；
(4) build water-permeable brick by laying bricks or stones：Treat concrete coagulation, concrete builds water-permeable brick by laying bricks or stones using the cement mortar fissure of displacement；
(5), after the completion for the treatment of that step (4) is built by laying bricks or stones, maintenance 3～5d can carry out packing job.
Described concrete is formed by the stirring of deads, cement and water.
The beneficial effects of the present invention is：
Using the filling counterfort of above-mentioned permeable brick masonry, its advantage is：
(1) good water permeability：Described water-permeable brick be respectively provided with good water penetration every pulp layer and pervious bed, can by discharge orifice
Quickly pervious bed drainage is discharged, accelerate permeable efficiency, shorten filling slurry gelling time；
(2) ooze slurry property low：Described water-permeable brick can be effectively isolated filling slurry every pulp layer, improve filling quality；
(3) intensity is high：Due to having excavated a foundation trench before building by laying bricks or stones to hardcore, and lay a layer concrete, then
Build the higher water-permeable brick of intensity by laying bricks or stones, filling counterfort can resist the pressure to barricade for the slip after filling；
(4) safety is good：Because filling counterfort building materials possess dehydrating function in itself, personnel need not enter goaf frame
If filter pipe, there is not roof fall accident risk；
(5) with low cost：Described water-permeable brick and concrete are all made up with deads of raw material, and it is former that filling counterfort is built by laying bricks or stones
Material cost is relatively low, and takes full advantage of the barren rock of down-hole generation, reduces land seizure, turns waste into wealth.
