DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The underground floor bottom leakage repair method of a building according to the present invention is a repair method for repairing cracks C formed in the basement floor B formed on the ground layer A as shown in FIGS. 1A and 1B, A water path forming step, a water path holding step, and a square groove sealing step.

First, the crack removing step is performed by forming a square groove 10 having a predetermined depth along a crack shape (cracked portion) appearing on the surface of the underground floor B as shown in FIGS. 2A and 2B, ) Is a concrete, a square cut 10 is formed by using a concrete cutter.

It is preferable that the width of the rectangular groove 10 is set to a maximum of 15 cm according to the degree of bending of the crack and is formed in a straight line state. When the degree of bending of the crack is too large to be accommodated within a width of 15 cm, Direction is formed to be inclined in the bending direction of the crack. The depth of the rectangular groove 10 may be a depth suitable for forming a water path at a later stage to be described later and holding the waterway, and preferably at least a depth shorter than the width of the square groove 10.

When one end of the rectangular groove 10 is connected to the drain port 20 in the case where the drain port 20 is located near the rectangular groove 10, the eluted water flowing into a water path described later is led to the drain port 20 So that it can be discharged.

In this case, if there is no drain 20 in the vicinity of the square groove 10 and there is a collecting filter 30 as shown in FIG. 2C, one end of the rectangular groove 10 is connected to the collecting filter 20, When the drain 20 and the collector 30 are not present or are too far from the square groove 10, a small house 10 is formed at one corner near the square groove 10, A crystal is formed and connected to the square groove 10.

2b and 2d, the process of vertically forming an induction hole 40 for introducing the eluted water into the square groove 10 at the bottom of the square groove 10 in the crack removing step .

2A, it is preferable to form a plurality of the guide holes 40 at regular intervals, for example, at intervals of 1 m along the square grooves 10, So that the elution water eluted from the underground of the repair area can be guided to the square groove 10.

When the filling material 50 made of gravel and sand is used in the water-forming step to be described later, the mesh net 41 is installed on the bottom of the square groove 10 so that the filling material 50 does not fall into the guide hole 40, (40).

Then, the water path forming step is performed by filling the filler 50 having a cavity capable of flowing the eluting water into the rectangular groove 10 as shown in Figs. 3A and 3B. The filler (50) is a mixture of small gravel and sand so that the elution water can flow through the gap between the small gravels.

Then, the water-holding step is performed by covering the upper and both sides of the filler 50 with the cover frame 60 except the bottom of the square groove 10 as shown in Figs. 4A and 4B.

The cover frame 60 may be a material that has relatively high structural strength and is not well corroded. For example, the cover frame 60 may be galvanized steel having a cross-sectional shape of "D", and the rectangular frame 10 may be continuously connected so as not to leak by welding the cover frames 60 against each other at the bent portions . Therefore, the cover frame 60 can keep the shape of the filler 50 made of gravel and sand from being deformed, so as to maintain the water path formed by the filler 50. [

On the other hand, when the gravel and sand are used as the filler (50) in the water-forming step, gravel and sand flow due to external factors such as flowing water and fine vibration can block the water.

Therefore, when the water path is blocked as described above, a device capable of piercing the waterway is installed. That is, the flow rope 61 is installed along the water path in the cover frame 60 before the filling material 50 and the cover frame 60 are installed as shown in FIG. 4C. The flow line 61 is guided by a plurality of guide rollers 62 which are arranged and fixed to the element elements along the water path.

4C, the flow line 61 is wound around a rotary handle 63 installed at the drain port 20 (or the liquid crystal collector) to move in the forward and reverse directions, and the flow line 61 A plurality of streamlined pressing bodies 64 for facilitating the movement of the flow stem 61 and the flow of the filler 50 when the flow stem 61 moves in the forward and reverse directions are provided along the water path. The flow line 61 is preferably made of a metal wire which is not corroded and has a high tensile strength.

5A and 5B, the mortar 70 is filled between the rectangular groove 10 and the cover frame 60 and the upper surface of the mortar 70 is connected to the bottom of the underground floor 10 B) surface of the rectangular frame 10 so that the mortar 70 is completely filled between the rectangular frame 10 and the cover frame 60 so that the rectangular groove 10 is completely sealed.

In this case, the waterproof coating step may further include a waterproof coating step of applying a waterproofing liquid to the sealing part and the bottom surface of the underground floor. In the waterproof coating step, the surface sealed with the mortar 70 as shown in FIG. 6, ) To form a waterproof coating layer (80).

2A, the cracks may be completely removed by forming a square groove 10 along a crack formed in the bottom of the underground layer, as in the crack removing step of FIG. 2A, 10) is sealed with the mortar (70), as compared with the conventional method in which the cement is injected into the crack gap, the seal is firmly made, and cracks can be prevented from recurring in the repair part.

In addition, a water path is formed by guiding the elution water eluted from the basement into the rectangular groove 10 and guided to the drain port 20 or the water collecting 30 to be discharged, It is possible to prevent recurrence of leaking water and to prevent the leaking water from leaking out over a wide range from the maintenance site to the periphery of the maintenance site by forming the guide hole 40 connected to the ground layer 10 in the rectangular groove 10. [ Can be guided to the waterway and discharged, thereby preventing leakage of leachate from other fragile parts.

On the other hand, when the gravel and sand are used as the filler 50 for forming the waterway, the gravel and the sand can flow in the course of the elution water, and can be clogged in any part of the waterway. Therefore, if the waterway is blocked, the drainage water can not be discharged to the drain hole 20 (or the water collecting hole), so that the water pressure in the waterway rises and cracks and leaks due to the leaking water may recur in the fragile portion of the waterway.

7, when the rotary handle 63 installed on the drain port 20 (or the water collecting compartment) is rotated in the forward and reverse directions, the flow line 61 installed along the water of the maintenance part is moved to the left and right Thus, since the streamlined pressing body 64 provided in the flow string 61 flows gravel and sand, it can be pierced by flowing gravel and sand covering any part of the waterway, So that it is convenient and can save time and cost due to maintenance.

It is to be understood that the embodiments described so far are merely illustrative of the preferred embodiments of the present invention and that the scope of the present invention is not limited to the embodiments described and that those skilled in the art, It will be understood that various modifications, substitutions or substitutions are possible, and such embodiments are within the scope of the present invention.
