Technical field
The utility model belongs to mine grouting for water blocking simulation test field, and in particular to a kind of examination of slip casting Seed harvest experiment
Block building mortion.
Background technology
Mine is being built in production process, and the surface water and underground water pour in mine by various channels, work as swallet
When more than proper drainage ability, mine water disaster is resulted in.Mine water disaster is common one of the major casualty of coal mine.In recent years, mine
Cement is incited somebody to action or chemical pulp passes through pipeline and is pressed into formation downhole gap, crack or lane by the widely used grouting and sealing technique of recluse person
In road, make its diffusion, solidification and hardening, to which rock stratum has higher intensity, density and impermeability, reaches closure and block
The effect of nourishment source and strengthening stratum, inflow rate of mine water, to prevent gushing water etc. from having obtained good for floor grouting reinforcing reducing
Good effect.But with the increase of mining depth, inflow rate of mine water also increases therewith, joint, crack in fractured coal and rock
Equal discontinuity surfaces just form conduit pipe, and coal and rock is caused to be rich in water, and water drenching occurs in top plate, and being brought to shaft production can not
The influence of ignorance.Therefore only development has water blockoff concurrently and the chemical slip casting material of reinforcement effect could be to being rich in water, watering state
Lower fractured coal and rock carries out effective chemical consolidation, and studies reinforcement effect and the resistance to compression of injecting paste material and broken coal petrography combination
There is also deficiency, test block makes complexity, cumbersome, has much room for improvement for strength test.
Invention content
In order to solve the problems in the prior art, the utility model proposes a kind of simple in structure, dismounting quickly, size mark
The test block building mortion of accurate slip casting Seed harvest experiment.
To achieve the goals above, technical solution is used by this implementation is novel：Including double molds, sleeve, end cap,
Grouting pump, slurry pool, drainpipe, water inlet pipe, Grouting Pipe, wherein double molds form cylindrical receiving sky after being closed
Between, it is inserted into the sleeve, with sleeve clearance fit；It is equipped with screw thread on the outside of the sleeve both ends, while being set on the inside of the end cap
There is screw thread, is threaded connection when the two coordinates；The end cap inside bottom is equipped with sealing rubber pad, thickness 0.1mm；The end
Lid includes the identical end cap of two sizes in left and right, and left-hand end is covered with a fluid hole, fluid hole internal thread and the outer spiral shell of drainpipe
Line transition interface coordinates blend rubber washer sealing, forms fluid hole and is connected to drainpipe；Right-hand end is covered with two inlet openings,
Inlet opening internal thread is connected to water inlet pipe and the cooperation blend rubber washer sealing formation of Grouting Pipe external screw thread transition interface respectively；Institute
It is adjustable to state grouting pump pressure size.
Further, internal diameter is 50mm, outer diameter 52mm when double molds are closed, and is highly 70mm.
Further, the sleeve diameter is 53mm, outer diameter 56mm, is highly 70mm.
Further, the water inlet pipe is connected to running water pipe, and the Grouting Pipe connects with the grouting pump, the slurry pool
It is logical.
Further, double molds, the sleeve, the end cap are stainless steel, the drainpipe, described
Water inlet pipe, the Grouting Pipe are plastic material hose.
The direct technology effect that above-mentioned technical proposal generates is that test block shaped structure is simple, easy to operate, and mold assembling is fast
Speed, test block size more standard eliminate the step of cutting processing forms reference block again, time-saving and efficiency, while above-mentioned dress
It is high to set gained test block consistency, also avoids the influence generated in being tested to later stage compression strength because test block size is uneven.
In conclusion the utility model is compared with the existing technology, structure is simpler, and mold attaching/detaching is quicker, gained
The more uniform standard of test block size makes multigroup test block suitable for slip casting Seed harvest simulation test.

Specific implementation mode
Below in conjunction with attached drawing, the utility model is described in detail.
As shown in Figure 1, the utility model structure：Including sleeve 1, double molds 2, end cap 3, wherein double molds 2
Cylindrical accommodation space is formed after closure, is inserted into the sleeve 1, with 1 clearance fit of sleeve；On the outside of 1 both ends of the sleeve
Equipped with screw thread, while 3 inside of the end cap is equipped with screw thread, is threaded connection when the two coordinates；3 inside bottom of the end cap is equipped with
Sealing rubber pad, thickness 0.1mm；The end cap 3 includes the identical end cap of two sizes in left and right, left side end cap 3（a）Equipped with one
