 The present invention relates to a waterproofing method of a water tank using a PE sheet, and more specifically, to the wall surface and the bottom surface of the water tank, one side and the other side of the PE sheet overlapping portion having a length extending over the wall surface and the bottom surface heat-sealing machine When thermally smelting, the present invention relates to a waterproofing method of a water tank using a PE sheet to allow automatic fusion using the heat fusion machine without any part to be manually fused.

In general, the water tank installed in the basement or roof of the building is usually made of a concrete structure, the waterproofing of the inner surface is essentially required due to the nature of the water contained.

Conventionally, the heat-treatment method was mainly applied to the inner surface of a water tank made of a concrete structure by using a thermosetting resin mainly composed of epoxy resin or glass fiber as a reinforcing material, but this was not only permanent but time-consuming, and wasted. There was a problem causing inconvenience.

Accordingly, in recent years, a waterproof structure using a polyethylene sheet (PE sheet) has been proposed as shown in FIGS. 1A and 1B. In general, the reservoir 110 is made of a concrete structure as described above, and has a substantially rectangular shape. Each wall surface 111 and the bottom surface 112 and the ceiling surface 113 formed in the lateral direction formed by the enclosure is formed, the one side wall 111 through the sleeve 114 penetrates the inner and outer In addition, both the wall 114, the bottom 112, and the ceiling surface 113 including the sleeve 114 are attached to the PE sheet 130 to be waterproof.

In addition, the reservoir 110 may have a wall protrusion pillar 116 formed on the wall surface 111 due to the structural limitation of the building, and the square pillar 117 may be formed at the center or the outer portion thereof. Protrusion pillar 116 and the square pillar 117 is also waterproof by the PE sheet 130, and as shown in Figure 1a is a variety of installations, for example, ladder 115 is installed inside the reservoir 110, The ladder 115 has a structure in which height can be adjusted up and down in general, and the upper and lower end sides are fixed to the ceiling surface 113 and the bottom surface 112 of the water tank 110 so as to be fixed.

Figure 2 is a cross-sectional view showing a waterproof structure by a conventional PE sheet, as shown therein to supply the PE sheet 130 along the inner surface of the reservoir 110 treated with the surface, washer 140a ) Is inserted into the tableting nail 140 inserted into the PE sheet 130 and fixed to the PE sheet 130. In order to prevent corrosion of the tableting nail 140 according to water contact, the outside of the fixing part is added to the sheet 150. It was fused and concealed.

In addition, as another example, as shown in Figure 3 by combining the tableting sheet 140 having a predetermined area on the inner surface of the reservoir 110, the base surface treatment with the tableting nail 140 fitted with the washer 140a After hitting and fixing to be arranged at a predetermined interval on the inner surface of 110, the method for heat-bonding the PE sheet 130 to the sheeting sheet 160 so that the sheeting sheet 160 is located approximately at the center portion. It has been proposed.

In addition, each end of the PE sheet 130 attached to the sheet for attaching 160 is superimposed on each other so that the PE sheet 130 is attached to the inner surface of the water storage tank 110 so as to be attached. , The construction using the PE sheet 130 is made over the wall surface and the bottom surface and the ceiling surface of the reservoir 110.

On the other hand, as shown in Figure 4, the corner portion of the reservoir 110 has a right angle with respect to the fold line 133, the upper and lower sides and upper and lower sides, here the lower surface 132, shown by a broken line. Folded to form, in which case the incision 134 is formed to fold the lower surface 132 first, and then the two sides (131, 131a) of the two sides (131, 131a) formed by the incision 134 The lower end wings 135 and 135a are formed by overlapping and heat-sealing on the lower surface 132.

In addition, the attachment method is similarly applied to the wall protrusion pillar 116 as shown in FIG. 5, except that both sides 131 and 131a and the lower wing 135 and 135a are folded in opposite directions. There is a difference, and the welding to the overlapping portion between the PE sheet 130 is used a heat welder 170 as shown in FIG.

The heat welding machine 170 is provided with a hot air nozzle 174 that emits hot air on the rear side of the upper and lower compression rollers 172 and 173 provided on the lower side of the base 171 so that the base 171 retreats. While first heating the overlapping portion of the PE sheet 130 with hot air, the overlapping portion of the heated PE sheet 130 passes through the upper and lower compression rollers 172 and 173 to the compression roller. By pressing, the thermal fusion is achieved.

In addition, in the case of a square pillar is attached to the PE sheet 130 along the horizontal and vertical wall surface as shown in Figure 7a and 7b, the boundary between the wall surface 117a and the bottom surface 112 is separate The welding unit 136 is formed by attaching the welding unit 136 by manual welding by hot air, or as shown in FIG. 7C, a lower wing 137 is formed at the lower end of each surface to weld the welding unit 136 along the lower wing 137. As a manual fusion by the), of course, the PE sheet 130 is of course attached to the heat-sealed adhesive sheet 160 of the tableting nail 140 is embedded in the inner surface of the reservoir tank (Fig. 2 and 3). Reference.)

FIG. 8 illustrates a state in which the PE sheet 130 is attached over the wall surface 111 and the bottom surface 112 of the water tank, and conventionally, the wall surface 111 and the bottom surface 112 as shown in FIG. 8. The end sheets facing each other are overlapped with each other on the sheeting sheet 160 fixed in a plurality of rows at regular intervals and thermally fused over the wall surface 111 and the bottom surface 112, and then the overlapping portions are fused. At this time, the edge portion, that is, the "A" portion forming the boundary between the wall surface 111 and the bottom surface 112 is made by manual fusion.

To describe this in more detail, a horizontal cut groove 134a is formed in the folded portions of the one side and the other side PE sheet 130a and 130b which are overlapped and bent to each other, and the PE sheet 130a into the inner side of the corner portion. After the folded portion of the 130b is in close contact with each other, the overlapping direction of the overlapping chip is shifted from the bottom surface 112 to each other and manually fused, and then the remaining portion is automatically fused with the heat fusion splicer.

9A illustrates a waterproof structure of the sleeve 114 installed through the inside and the outside of the reservoir 110, wherein the sleeve waterproof portion 180 surrounds the outer circumference of the sleeve 114 with a sealing material 181. In addition, after wrapping the PE sheet 130 in a circular shape on the outer circumferential surface of the sealing material 181, the PE sheet 130 is fixed with at least two or more SUS bands 182 to be waterproof to the sleeve 114. To be done.

Figure 9b shows another embodiment of the sleeve waterproofing, which is fixed before welding the fixed flange (183) by tapping the one end of the sleeve 114 before the concrete casting, and the water tank by concrete pouring and curing To form the 110, the inner surface of the reservoir 110 is waterproofed using a PE sheet 130 including a nonwoven fabric 120, as described above, wherein the PE sheet 130 on the sleeve 114 ) And the nonwoven fabric 120 is removed so that the sleeve 114 can communicate with the interior of the water reservoir 110, and the fastening flange 184 together with the packing 185 is rubber-packed to the fixed flange 183. 186 is fastened with a bolt 187 to be waterproofed to the sleeve 114.

 However, in the waterproof construction method of the water tank using the conventional PE sheet, when the one side and the other side PE sheet 130 is superimposed and attached over the wall surface 111 and the bottom surface 112 of the water tank, as described above. The automatic fusion using the heat welding machine is not performed on the edge portions that border each other.

That is, the heat fusion splicer 170 is generally retracted while spraying hot air through the hot air nozzle 174 on the lower side of the base 171 as shown in FIG. 6 and overlapping the overlapped portion of the preheated PE sheet 130. Since the compression is performed while passing between the upper and lower compression rollers 172 and 173 to achieve heat fusion, the heat fusion unit 170 as shown in Figure 10 the reservoir 110 at its boundary portion as shown in FIG. Manual fusion is inevitable because it can no longer move back to the wall 111 or bottom 112 of the.

In addition, during the manual fusion, the incision grooves 134a must be formed in the folding portions of the PE sheets 130a and 130b such that the PE sheets 130a and 130b closely adhere to the corner portions forming the boundary, and overlap each other again. There is a lot of work maneuvering such that the overlapping direction of the parts to be overlapped with each other is caused, which not only induces inconvenience and inconvenience, but also requires a lot of work time, resulting in a rapid decrease in construction and inefficiency. there was.
