As it is well known, groundwater (subsurface water) refers to water flowing or flowing in gaps between underground strata and rocks. In recent years, various pollutants have been mixed with ground water, and the quality of groundwater is deteriorating .

In general, although the groundwater harvesting device is not shown in the drawings, the outer rock is excavated to the rock layer where the weathered rock layer ends by using a rocker of a predetermined thickness, and then out casing of the large diameter installed to prevent the collapse of the weathered rock layer. After the casing, excavate the rock bed again to penetrate the water vein and then the in casing installed to prevent the inflow of surface water, and the inflow of soil water or foreign substances in the ground where the ground water is moved to the lower part of the casing. A strainer pipe which is installed to be prevented, concrete that is cured by injecting concrete to prevent the inflow of foreign substances such as surface water into the space between the encasing and the groundwater core wall, and a heart pump installed inside the casing; Is installed to be connected to the cardiac pump and by the cardiac pump And a pumping water pipe through which groundwater to be pumped is moved.

In addition, in order to improve the water quality due to contaminated groundwater, it is necessary to remove all incrustations inserted inside the existing heart and remove the inside of the heart, -33646, which is a patent application for a groundwater pipe, and has been carried out through a grouting method and a grouting method.

However, this technology had to draw out all the casings inserted in the inside of the heart to the outside, and in the process, there was a case that the accident occurred in the heart of the heart, and there was a case of republication. There is a need for a technique for grouting between the in casing and the heart wall.

There is a patent application No. 1999-7203 (Invention: Groundwater cardiac packer, water vein cleaning device, and water vein cleaning method using liquefied carbon dioxide), which was invented and applied by the present inventor using the conventional technology as described above. In the related art, a plurality of holes may not be punctured in the incasing pipe, thereby causing a problem in that the freezing shielding film should be installed inside the incasing pipe, and thus, the inflow of groundwater cannot be smoothly shielded.

In order to solve such a problem, there is a patented invention No. 10-0460127 (hole perforation and freeze shielding film forming apparatus for grouting injection).

The patent is to drill a plurality of holes at regular intervals by using a drill in the encasing pipe, and to use a packer to form a freeze shielding film between the encasing pipe and the deep hole wall. In addition, after forming the freeze shielding film, a grouting solution is injected between the encasing pipe and the cardiac hole wall to form a lining wall cement, thereby improving workability and work efficiency. This greatly improves the quality and reliability of the product.

However, the 10-0460127 is composed of a separate unit having a first configuration (drill, etc.) for drilling holes in the casing, and a second configuration (grouting injection holes, etc.) for grouting injection through the perforated holes. After inserting the composition into the heart and drilling the hole, when the drilling of the hole is completed, the first composition must be withdrawn from the heart and the second composition must be inserted and grouting, which is cumbersome. The disadvantage is that the air is long.

In addition, there is a problem that the grouting hole is opened and the grout material is introduced into the interior.

In addition, since both the drilling and grouting work of the grouting hole is made by the manager's sense, all work such as drilling and grouting takes a long time, and there is a problem in that work defects occur.

In addition, when the hole is drilled in the casing, chips cut in the casing are generated, and the chips remain in the periphery of the drill and inside the casing, and the chips are caught in the driving part such as the drill, thereby preventing malfunction and damage of the driving part such as the drill. There are also disadvantages that occur.
