Description
Technical field
The utility model relates to coal mine flood Prevention Technique fields, and in particular to a kind of grouting for coal mine flood prevention and treatment
Device.
Background technique
Coal mine flood influences the progress and quality of mine engineering construction, deteriorates the work situation of worker, increases the row of mine
Drainage facility and effluent cost bring insecurity factor to coal production, and serious person even floods well accident, cause life and
The heavy losses of property easily link up old cellar ponding, make vehicle mine perviousness accident, coal mine flood during coal mining
Accident also results in country rock and corrodes reduction, induces secondary disaster, and water resource is destroyed, and resource can adopt rate reduction, ton coal effluent cost
High, China's coalfield-hydrogeology complicated condition, there are about 18% coal reserves to be exploited by more serious in China at present
Water damage threaten, preventing and controlling are carried out to it with important and urgent realistic meaning.
The leakproofness of existing injected hole is poor, and slip casting casing, also vulnerable to resistance, influences to infuse into when being drilled ground hole
Work is starched, in slip casting work, injected hole is easily blocked, and influences slip casting efficiency, increases worker's work difficulty, increases the working time.
A kind of coal mine flood of Chinese patent prevents and treats device（Authorization Notice No. is：CN205206784U）, the patent using fall
Thorn is smooth to solve the problems, such as, but when grouting sleeve is drawn out, hangnail can have biggish resistance.
Summary of the invention
When the utility model is that solution slip casting casing entrance has been drilled ground hole, vulnerable to resistance, and in slip casting work,
The technical issues of injected hole easily blocks, and influences slip casting efficiency provides a kind of provisions for grouting for coal mine flood prevention and treatment.
In order to solve the above technical problems, technical solution used by the utility model is：One kind is prevented and treated for coal mine flood
Provisions for grouting, including grout pipe sets gradually several Unidirectional solenoid valves on the side wall of grout pipe, tube top of being in the milk from top to bottom
Portion is connected with grouting hose；The top of the grout pipe is rotatably connected to horizontally disposed support plate, and the both ends of support plate are fixed
It is connected with the telescopic mast being vertically arranged；On grout pipe positioned at support plate top part fixing sleeve be equipped with first gear, first
It is engaged with second gear on the right side of gear, is fixedly connected with shaft on the downside of second gear, the shaft is connected with motor, the motor
Fixed setting is on the supporting plate.
When using provisions for grouting, telescopic mast is fixedly connected with the ground, grout pipe enters pore interior, when grout pipe into
When entering gap and being obstructed, start motor, motor drives shaft rotation, and shaft drives second gear rotation, and second gear drives first
Gear rotation, first gear drive grout pipe rotation, while telescopic mast being made to drive support plate decline, then grout pipe is in the same of decline
When rotate, effectively realize grout pipe facilitates placement.Grouting works are carried out, Unidirectional solenoid valve is opened, injection slurry is from unidirectional electricity
Progress grouting treatment in gap is entered in magnet valve, but injection slurry will not be inversely flowed into grout pipe, realize Cementer
That makees goes on smoothly.
The utility model has the advantages that compared with prior art：
The injection slurry of the utility model provisions for grouting is entered out of Unidirectional solenoid valve carries out grouting treatment in gap, still
Injection slurry will not be inversely flowed into grout pipe, realize going on smoothly for slip casting work；First gear drives grout pipe rotation,
Telescopic mast is set to drive support plate decline simultaneously, then grout pipe rotates while decline, effectively realizes conveniently putting for grout pipe
It sets.The utility model has many advantages, such as that reasonable in design, grouting is convenient and will not flow backwards and decline smooth, has certain push away
Wide application value.
