Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproofing method, and more particularly,
The parking lot can be constructed outdoors, on the ground, indoors or underground of various buildings, or in a separate parking building. The floor is made of concrete, mortar or iron plate. The floor of the parking lot should be treated with waterproof flooring to prevent corrosion of steel plates or reinforcing bars due to water or leakage of water to the lower layer. It should be treated so as to reduce the running noise of the vehicle, to withstand the running impact of the vehicle and to prevent the vehicle from slipping Should be processed.
For example, the floor of the parking lot should be waterproofed according to the flow characteristics of water, the characteristics of the waterproofing material, the concrete condition, and the external environment requirements. If the water content of the floor is high, the waterproof layer adheres to the floor and adversely affects the performance of the material. After construction, due to shrinkage and expansion caused by temperature change or impact, air pockets may be formed between the floor and the waterproof layer, pinholes may be formed in the waterproof layer, and the waterproof layer may be torn or broken. If these problems occur, repair work must be done.
Also, even if maintenance is performed by the same waterproofing method, the same problem arises, and maintenance and repair of the floor of the parking lot is expensive, so it is necessary to prevent this.
However, the conventional technologies only provide a waterproofing method for building construction, and there is no known method for systematically repairing water leakage when it occurs.
However, only a method of repairing and reinforcing the surface of a point where leakage occurs is disclosed in "Method for repairing complex waterproofing of concrete inner wall surface" (Korean Patent Registration No. 10-0354135, Patent Document 1).

The cold joint means that the concrete which has been previously laid is laid on the concrete after the concrete laid first is hardened and the concrete laid thereon is stacked when the concrete is poured, It refers to the part that occurs due to the time difference in curing.
These cold joints do not match the quality of the concrete, which creates a discontinuity and is the main passage through which the water flows. The water in the cold joint part is repeatedly frozen and melted, causing corrosion of steel bars, lowering the strength of the concrete and lowering the watertightness, thereby promoting leakage of the underground parking lot.
The cold

In this waterproofing step, it is desirable to form the piercing depth up to 2/3 of the thickness (D) of the underground floor structure.
Work on condensation (s600)
FIG. 18 is a view for explaining a condensation phenomenon, and FIG. 19 is a view for explaining a method of filling a packing material in order to prevent condensation of FIG.
If the surface temperature of the structure and the temperature in the air are different, the moisture in the air will become water droplets, causing condensation that looks like a leaking phenomenon. In this case, the construction cost due to the waterproofing work is increased, so that the construction for preventing the condensation phenomenon can be added.
18 shows that the surface condensation of the structure is formed, and FIG. 19 shows that condensation occurs inside the structure.

When the coarse objects (P) are piled up inside the structure, condensation inside the structure frequently occurs. The internal condensation can be blocked by inserting the heat insulator diagonally upward from below the under ceiling.
