Abstract
The invention belongs to the technical field of in-situ leaching mine gravel filling type structure drilling construction, and particularly relates to a gravel pump gravel filling method. According to the technical scheme, a gravel pump (11) is used for injecting water and throwing gravels into a gravel throwing pipe (19), when gravels are thrown, gravel (13) filling heights are measured, when the gravels (13) reach the required height position as designed, cement is used for sealing holes, and the gravel throwing pipe (19) is used for measuring the gravel filling height. Due to the fact that injection pressure of the gravel pump (11) is small, once the filling gravels (13) are flush with an opening of the gravel throwing pipe (19), the gravel pump (11) stops throwing gravels, water returns from a gravel throwing funnel (12), the gravel throwing height can be measured according to the principle, and quantification control of gravel throwing is achieved. By means of the technical scheme, gravel filling speed is high, efficiency is high, gravel filling position is precise, and pollution of mud on ore beds is reduced due to the fact that drilled holes are flushed when gravel is thrown.
Description
Technical field
Soak mine with the invention belongs to and fill out gravel formula structure boring construction technique field, relate in particular to a kind of gravel pump and fill out gravel method.
Background technology
In recent years, ground soaks production technique and obtains fast development at low-grade sandrock-type uranium deposit, and boring is to realize important channel and the link that ground-dipping uranium extraction is produced.Ground-dipping uranium extraction injects ore bed by liquid injection hole by leaching solution, by drawing liquid hole, leachate is promoted to earth's surface, has just realized the ground of taking out continuously note just soak cyclic process by these special " passages " of boring.Filling out gravel formula hole structure is that the ground of commonly using soaks hole structure, has been widely used at present well, but generally well well depth is between tens meters to tens meters, and the degree of depth is less, and difficulty of construction is also lower.Be that more than 150m ground soaks boring and adopts while filling out gravel formula hole structure again in the degree of depth, how filling out accurately gravel becomes a large technical barrier, has restricted and has filled out the application of gravel formula hole structure on ground soaks.Available technology adopting is manually thrown gravel, not only length consuming time, to throw gravel pin-point accuracy poor, and throws the local problems such as bridge formation that easily occur of gravel pipe.
Summary of the invention
The object of the invention is for prior art length consuming time, to throw gravel pin-point accuracy poor and throw the local technical problem of building bridge of easily occurring of gravel pipe, provide a kind of and filled out that gravel speed is fast, the time is short, efficiency is high, filled out gravel pin-point accuracy, drilling slurry polluted little gravel pump and filled out gravel method.
The technical solution used in the present invention is: a kind of gravel pump is filled out gravel method, in turn includes the following steps:
Step 1, be mounted to the position lower than strainer lower end by throwing gravel pipe;
Step 2, unlatching slush pump valve, start slush pump and supply water to gravel pump, restarts gravel pump and pump into clear water in backfill gravel material space;
Step 3, after water is returned in aperture, add the gravel material through cleaning to throwing gravel funnel, while starting to throw in gravel material, first evenly add a small amount of gravel material, after gravel material conveying uniform is smooth and easy, increase again the injected volume of gravel material;
Step 4, throw in to throwing gravel funnel water burst or backfill gravel material space upper end open while not returning water when gravel material, throwings gravel pipe is upwards carried to 2 to 3 meters, continue input gravel material;
Step 5, repeating step 3 are to step 4, and gravel material is upwards filled piecemeal until design attitude in inherent filtration device bottom.
The equipment that the present invention adopts comprises connected successively slush pump, gravel pump, sand water mixing carrier pipe, water tap and throwing gravel pipe, slush pump is connected with gravel pump by flange, gravel pump is tightly connected by screw thread with throwing gravel pipe, water tap is connected by pipe collar with throwing gravel pipe, throwing gravel pipe is placed in backfill gravel material space, throw on gravel pipe and there are some ball valves, throw gravel pipe for opening and closing.Well casing is placed in backfill gravel material space, and top has well mouth sealing device, and well mouth sealing device top has pressure meter and one end steel pipe being connected by pipe collar, and ball valve is installed on steel pipe.
Described slush pump comprises water sucking mouth, slush pump motor, valve, return pipe and high-voltage tube, and lower end, water sucking mouth is placed in aqua storage tank; Described gravel pump comprises water inlet, gravel pump motor, throwing gravel funnel and gravel pump clear water, the outlet of gravel material, and above-mentioned slush pump and gravel pump all belong to equipment of the prior art.
The useful technique effect of the present invention is: technical scheme of the present invention adopts gravel pump to throw gravel from throwing water filling in gravel pipe, gravel height is surveyed on Tou Li limit, limit, gravel height carries out cementing for reaching designing requirement position, fills out gravel height by throwing the detection of gravel pipe simultaneously.Because sandstone infusion pressure is less, once enclose the concordant throwing gravel of the gravel material mouth of pipe of filling out, gravel pump is no longer thrown gravel, throws gravel mouth and can return water, may detect and throws gravel height according to this principle, accomplishes the quantified controlling of throwing gravel.Adopt technical scheme of the present invention to fill out that gravel speed is fast, efficiency is high, it is accurate to fill out gravel position, water filling is rinsed boring when throwing gravel simultaneously, has reduced the pollution of mud to ore bed.
