1 and 2, the groundwater discharging apparatus according to an embodiment of the present invention includes a lot 100, a center lot 200, an upper tube 300, a core tube 400, And may include a lower tube 500 and a drill bit 600.

The lot 100 may be connected to a driving source such as a motor.

In the center lot 200, the lot 100 is rotated. The center lot 200 may be formed to be long in the axial direction of the groundwater pouring device through the upper pipe 300, the core tube 400, the lower pipe 500, and the drill bit 600. A water inlet 220 connected to a pump for supplying water may be formed in the center lot 200. Water injected into the water inlet 220 may be formed by perforating the periphery of the center lot 200 And can be discharged through the water discharge hole 210.

Water discharged into the water discharge hole 210 can be used for rock friction.

A slush accommodation space is formed in the upper pipe 300 to store and discharge soil and stones generated during the expansion work.

The upper tube 300 is formed so as to include the upper end of the center lot 200 at the inner center thereof. Specifically, the upper tube 300 may include a cylindrical body 310, a center tube 320, and a spoke portion 330.

Referring to FIG. 2, the cylindrical body 310 forms a slush receiving space (S in FIG. 2) therein. A center pipe 320 is provided at the center of the cylindrical body 310, and the center pipe 200 is inserted into the center pipe 320. The cylindrical body 310 may be embodied in a clogged form to contain stones or soil that occur during the spreading operation.

The spoke portion 330 radially connects the outer circumferential surface of the center tube 320 with the inner tube of the cylindrical body 310. The spokes 330 may be formed by combining the center lot 200 and the cylindrical body 310 while ensuring the slush accommodation space S in FIG. 2, so that the upper tube 300 rotates in conjunction with the rotation of the center lot 200. .

On the other hand, a slime discharge hole 340 may be formed around the upper tube 300. The slime discharge hole 340 serves to discharge the stone or soil contained in the slush receiving space to the outside of the upper pipe 300. A plurality of slime discharge holes 340 may be formed along the circumference of the upper tube 300.

The diameter of the upper tube 300 can be appropriately designed in consideration of the diameter of the boss.

The core tube 400 may be detachably coupled to the lower end of the upper tube 300. The central portion of the center lot 200 is coupled to the inner center of the core tube 400 to rotate in conjunction with the rotation of the center lot 200. The core tube 400 may be formed with a closed top surface.

The diameter of the core tube 400 may be the same as the diameter of the upper tube 300.

The lower tube 500 may be detachably coupled to the lower end of the core tube 400. The core tube 400 and the lower tube 500 are configured to rotate in conjunction with the upper tube 300 of the lower tube 500.

FIGS. 3 and 4 are views showing a wringing operation using the groundwater discharging apparatus shown in FIG. 1, FIG. 5 is a view showing a belt-type lifter, and FIG. 5 is a view showing a drill bit.

3 and 4, the centering rod 200 is inserted into the casing 1a formed on the paper 1, and the waving operation is started. 3B, soil or stone can be contained inside the upper pipe 300 when the expansion is progressed.

3 to 5, the lower pipe 500 may include a belt-type lifter 510. The belt-type lifter 510 presses and tightens the grouting region 1b so that the grouting region 1b is lifted together when the lower tube 500 is lifted. The belt-type lifter 510 has a long belt-like shape. The outer surface 511 of the belt-type lifter 510 is formed so as to be inclined so as to abut the inclined surface 514a of the lower tube 500. And the engaging teeth 513 protrude from the inner surface 512 of the belt-type lifter 510. [

The engaging teeth 513 may be formed so that the lower surface of the engaging teeth 513 is longer than the upper surface of the teeth so that the edges of the teeth are upward. The upper surface of the engaging teeth 513 may be formed to be perpendicular to the inner surface 512 of the belt-type lifter 510. When the lower pipe 500 is excavated and moved downward, the frictional force is minimized. When the lower pipe 500 is lifted upward, the frictional force is maximized to move the belt-type lifter 510 downward to tighten the grouting area. A plurality of these latching teeth 513 may be formed over the entire area of the inner side surface 512 of the belt-type lifter 510.

The thickness D1 of the upper end 514b of the groove 514 in the radial direction is smaller than the thickness D1 of the belt type lifter 510 so that the belt type lifter 510 can be inserted and moved. And the width W1 of the groove 514 in the height direction may be formed to be larger than the width W2 of the belt-type lifter 510. In this case,

6 is a view showing a drill bit.

Referring to FIGS. 1 and 6, the drill bit 600 is coupled to the lower end of the lower pipe 500 to physically crush the grouting area. As the lower tube 500 rotates, the drill bit 600 rotates and breaks through the grouting area. The drill bit 600 may be detachably connected to the lower pipe 500 through the connection portion A. [ As a result, the operator can easily replace the metal tip 610 by separating the drill bit 600.

5, the metal tip 610 may be alternately formed on the inner side and the outer side with respect to the lower end of the drill bit 600. [ This is to facilitate the coupling relationship with the core tube 400.

As described above, the groundwater discharging apparatus according to one preferred embodiment of the present invention has been specifically described with reference to the accompanying drawings.
