Description

Water stop for pumping water in hydrogeology drilling

Technical Field

The utility model belongs to the technical field of hydrogeology, concretely relates to waterstop that hydrogeology drilling was taken water.

Background

In the hydrogeology reconnaissance process, often need drill hole to ground, drilling depth sets for according to surveying the requirement, after drilling accomplishes a period, can accumulate the water that the soil layer oozed in the drilling, and accessible pumping equipment takes these water out for detect.

Adopt the water pump at present to draw water the in-process, because the stratum normal water composition is different, consequently in the in-process of drawing water in order to prevent upper water by the suction, can be at the position installation water stop of drawing water, current water stop main part is for having the aqueduct, the soft cover of inflation and screwed joint constitute, the soft cover both ends of inflation are sealing connection aqueduct and screwed joint respectively, screwed joint connects the water pump and absorbs water female connector on the pipeline, when drawing water, water passes through in the aqueduct gets into the soft cover of inflation, then the soft cover of inflation is intake and is expanded, make its outer wall take off tight drilling inner wall, thereby can prevent upper water entering lower floor's aquatic, the weak point that exists is: when the lower water quantity is less, the water sucked through the water guide pipe is not enough to enable the outer wall of the expansion soft sleeve to tightly pull the inner wall of the drill hole, and the water stopping effect is difficult to achieve.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hydrogeology drilling water stop that draws water to when the lower floor water yield is less among the solution prior art, be difficult to reach the problem of stagnant water effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a hydrogeology drilling water stop that draws water, includes the siphunculus, the suction tube has been installed to the one end of siphunculus, the other end of siphunculus is connected with the screwed pipe, the overcoat frame has been installed to the outer wall of siphunculus, the cover is equipped with the soft cover of inflation on the overcoat frame, the outer wall hoop of overcoat frame is equipped with the hole of arranging, the both ends of compressing tightly the soft cover of inflation of snap ring and snap ring are installed to the outer wall both sides of overcoat frame, be equipped with the gas pocket on the overcoat frame, the port of gas pocket has been installed air pipe.

Preferably, the thickness of the inflatable soft sleeve is at least two millimeters.

Preferably, the number of the discharge holes is at least four.

Preferably, one end of the air pipe is provided with a bidirectional air pump, and the air pipe is respectively connected with an air inlet end and an air outlet end of the bidirectional air pump.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a hydrogeology drilling draws water's sealing up ware, make a round trip to push down the depression bar, gaseous row to the overcoat frame in through the gas pocket, then arrange to the inflation flexible sleeve in through the discharging hole, the inflation flexible sleeve is constantly outwards expanded, until compressing tightly the drilling inner wall to can effectively organize upper water and get into lower floor's aquatic, under the condition that lower floor water content is few, prevent to draw water in-process upper water gets into lower floor's aquatic, solved when the lower floor water yield is less, be difficult to reach the problem of stagnant water effect.

fig. 3 is a schematic sectional top view taken at a-a of fig. 1.

In the figure: 1 through pipe, 2 suction pipe, 3 screwed pipe, 4 outer frame, 5 expansion soft cover, 6 discharge hole, 7 snap ring, 8 air hole, 9 air pipe joint, 10 air pipe, 11 two-way air pump.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1, 2 and 3, a hydrogeological drilling water pumping water stopper comprises a through pipe 1, a suction pipe 2 is arranged at the lower end of the through pipe 1, the suction pipe 2 and a threaded pipe 3 are integrated by fusion casting, the upper end of the through pipe 1 is connected with the threaded pipe 3, the threaded pipe 3 is used for being in threaded connection with an internal thread joint on a water suction pipeline of a water pump, an outer sleeve frame 4 is arranged on the outer wall of the through pipe 1, the outer sleeve frame 4 is of a circular ring type frame structure, the through pipe 1 and the outer sleeve frame 4 are integrated by fusion casting, an expansion soft sleeve 5 is tightly sleeved on the outer sleeve frame 4, the thickness of the expansion soft sleeve 5 is two millimeters, discharge holes 6 are circumferentially arranged on the outer wall of the outer sleeve frame 4, the number of the discharge holes 6 is four, and gas in the outer sleeve frame 4 is discharged into.

Referring to fig. 1 and 2, the upper and lower sides of the outer wall of the outer frame 4 are provided with snap rings 7, the snap rings 7 are of a circular structure with a double right-angled bevel in cross section, the snap rings 7 and the outer frame 4 are a fusion casting integral piece, the snap rings 7 compress the upper and lower ends of the inflatable soft sleeve 5, the upper and lower sides of the inner wall of the inflatable soft sleeve 5 are tightly clamped on the outer wall of the outer frame 4, so that the gas in the inflatable soft sleeve 5 can be prevented from being discharged through a gap between the inflatable soft sleeve 5 and the outer frame 4, the left and right sides of the upper end of the outer frame 4 are respectively provided with air holes 8, the port of each air hole 8 is welded with an air pipe joint 9 in a seamless manner, the air pipe joint 9 is connected with an air pipe 10, the length of the air pipe 10 is 10 meters, the type of the air pipe joint 9 is SF, the air pipe 10 is respectively connected with the air inlet end and the air outlet end of a bidirectional air pump 11, when the bidirectional air pump 11 is rotated to reversely suck air, the pressure rod is pressed down back and forth, so that air can be sucked into the expansion soft sleeve 5, and when the pressure rod is stopped being pressed down back and forth, the pressure-type one-way air valves in the air inlet end and the air outlet end of the bidirectional air pump 11 can prevent the air in the expansion soft sleeve 5 from flowing back into the bidirectional air pump 11.

During the use, can be with 3 threaded locking water pump water absorption pipe of screwed pipe female adapter on the pipeline, the degree of depth that will inhale 2 downstream to need draw water, when aerifing two-way air pump 11 rotatory to the forward, make a round trip to push down the depression bar, it is gaseous through 8 rows of gas pocket to the overcoat frame 4 in, then arrange to the soft cover of inflation 5 in through arranging hole 6, the soft cover of inflation 5 is the outward expansion constantly, until compressing tightly the drilling inner wall, thereby can effectively organize upper strata water entering lower floor aquatic, after finishing drawing water, when breathing in two-way air pump 11 is rotatory to the reverse, make a round trip to push down the depression bar, can breathe in the soft cover of inflation 5, the soft cover of inflation 5 breaks away from attaching to taking off of drilling inner wall, thereby under the condition that the lower floor water content is few, prevent to draw water in-process upper strata water entering lower.
