Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for preventing land subsidence by pressurizing recharge water and preventing clogging of a strainer (9) in the Richard II method.

[0002]

[Prior art]

 Pumped water from well points and deep wells is measured in a tank to discharge water, connected to a recharging water pipe, and returned to the reduction well by gravity.

[0003]

[Problems to be solved by the invention]

 The rate at which the injected water penetrates into the ground depends on the pressure of the injected water. In the conventional method, the injected water is injected into the well for reduction by gravity, which requires a long operation time.

[0004] In the conventional method, there is a problem that clogging occurs because the temporarily pumped groundwater is exposed to air above the ground and then injected.

[0005]

[Means for Solving the Problems]

 Drilling while sampling with a boring machine, determining the strainer position and eye size based on the data, and connecting the pumped water directly to the reduction well. , Leading to higher efficiency.

[0006] A device equipped with a rotating spiral auger to increase the permeation speed of the injection water.

[0007]

[Embodiment of the invention]

 1, 2, 3 and 4 will be described with reference to the drawings based on the embodiment. 1, 2 and 3 are explanatory views showing an embodiment, and FIG. 4 shows an application example.

1 to 3, the structure itself of the double pipe (20) is common, and the structure will be described. The bottom of the outer tube (1) has a downward conical shape, in which fine soil particles, fine sand and other residual evaporates are accumulated and can be pumped up with a vacuum hose.

[0009] The injection water is introduced into the upper part of the inner pipe (2) through the introduction pipe (3), and the injected water discharged there proceeds down the inner pipe (2) and is inverted at the bottom of the outer pipe (1). And rises between the outer pipe (1) and the inner pipe (2). As it rises, it is extruded from the strainer (9) cut off the outer pipe (1) and penetrates into the soil.

[0010] The lid that hangs on the outer pipe (1) and the inner pipe (2) is a closed type that is detachable, and a spiral auger (5) is suspended from the center of the lid into the inner pipe (2) and can be rotated. is there.

The outer pipe (1) is in direct contact with the soil, and a strainer adapted to the soil in contact with the outer pipe is provided. The inner pipe (2) is a straight pipe suspended from the upper lid. There is a sufficient space between the base plate and the bottom plate of 1). When the flow of the injection water is reversed at the bottom, maintain a space that does not wind up the fine soil particles, fine sand, residual evaporate, etc. accumulated at the bottom. ing .

[0012] In the gap between the outer pipe (1) and the inner pipe (2), the injected water slowly rises, and fine soil particles, fine sand, residual evaporates, etc., which enter from the strainer of the outer pipe (1) rise. It is a device that keeps the space so that it can descend gently against the injected water.

[0013] The lids of the outer pipe (1) and the inner pipe (2) are closed spaces, and the flow of the injected water that could not be absorbed by the soil is measured as excess water in the notch tank (12). The structure is discharged into the groove (13).

Referring to FIG. 1, the motor (4) and the spiral auger (5) will be described. When there is no water pressure of the injection water flowing from the introduction pipe (3), the spiral auger (5) is rotated by the motor (4) to pressurize and inject the injection water.

Referring to FIG. 2, the water turbine blade (7) and the spiral auger (5) will be described. When the injection water flowing into the inner pipe (2) from the inlet pipe (3) has some water pressure due to the relative position of the pumping position and the height of the Super Richard II well, the injection water is insulted from the spout (6). Then, the turbine blade (7) is rotated, and the spiral auger (5) is used to pressurize and impregnate the injected water.

Referring to FIG. 3, the downward spout (8) and the spiral auger (5) will be described. When the injection water flowing from the inlet pipe (3) flows in with a considerable water pressure, the injection water is jetted downward by the downward jet port (8), and the spiral auger (5) is rotated by the momentum. This is a device that generates water pressure and permeates injected water without diffusing fine soil particles, fine sand, residual evaporation, etc., which accumulate at the bottom of the outer pipe (1).

FIG. 4 shows an application example. The water pumped by the submersible pump (16) from the deep well facility (15) is drawn in by the water supply pipe (14), and is discharged from the introduction pipe (3) to the inner pipe (02). The injected water descends while being pressurized by the rotation of the spiral auger (5), reverses at the bottom of the tube, and is pushed out of the outer tube strainer while slowly rising between the inner and outer tubes. An impermeable layer shall be provided near the ground surface with clay or the like to prevent it from erupting to the ground surface. The water that has not penetrated is discharged into the notch tank (12), and after measuring the flow, is discharged into the drain.

[0018]

[Effect of the invention]

 Reduced water is pressurized and penetrated, increasing the effect of preventing land subsidence. Clogging of the strainer can be eliminated by using a strainer adapted to the soil, and connecting the pumping pipe and the pipe for Richard II directly without contacting the air.
