Description

The water drain sheet and the that used water drain methods}

The present invention relates to a drainage sheet used for underground irrigation and drainage in cut land slope, tunnel, farmland, golf course, general building construction of roads and drainage method using the same.

The present invention relates to a drainage sheet and a drainage method using the same, and in particular, made of flexible, thin and weather resistant thermoplastic synthetic resin used for underground irrigation and drainage in cut slopes, tunnels, farmland, golf courses, and general buildings. It relates to a drainage sheet and a drainage method using the same.

The most common drainage system used for underground irrigation and drainage in civil works is the formation of crushed stone or gravel layers to treat the infiltrated water. However, recently, permeable pipes, drain plates, and drainage sheets are used for underground irrigation and drainage. The use of technology to prevent the penetration of the basement or condensation of the general building is the mainstream.

According to the drainage plate according to the Korean Patent No. 367108 and the drainage method using the same, the bottom layer of the building by the drainage plate consisting of a plate formed with a plurality of holes and a core means integrally formed or attached to a thin film having flexibility under the plate It is installed directly on the bottom floor without the waterproof part or waterproofing layer between the bottom concrete structure and the bare concrete, and then the concrete impregnated water and condensation water induced between the cores of the drain plate by draining concrete or mortar on the upper part of the drain plate. Is done.

The drainage method using the drainage plate fills the soil layer between the hole and the plate, which is used for underground irrigation and drainage in cut slopes, tunnels, farmland, golf fields, and general buildings in concrete roads without concrete or mortar. This results in the drainage blockage.

In addition, it is used as a drainage plate for groundwater drainage in civil engineering, such as roads or railway tunnels, as in Korean Patent No. 777800, and a non-woven fabric is provided in the lower part of the support piers with a plate body having a cup-shaped support piers formed on its bottom surface. It is also applied to other construction methods that cover the drainage plate and cast concrete on the drainage plate, or cover the drainage plate in the crushed gravel layer, which is basically poured, so that the supporting piers at the bottom of the drainage plate are spaced between the supported bottom surface and the gap. Although it is characterized by the formation of a passage, such a drain plate is easy to apply mainly to the drainage facility in the tunnel of the road or railway, but also cut slopes, tunnels, In farmland, golf course, general building construction, after using for a long time It can be seen that the result is a flowing soil along the path is not crushed gravel layer flows into the lower space to be closed the pier, the effect is the half predicted.

On the other hand, according to a strap drainage material such as US 005934828 A, a capillary tube is formed in the narrow cleavage grooves of the small diameter drainage collection holes extending in the longitudinal direction of the thin strap drainage embedded in the soil cover and provided compactly on the surface thereof. It consists of a drainage sheet to absorb the water contained in the soil cover into the groove by the action, to absorb and release the water by the siphonic force formed by the lowering of the water level in any portion of the grooves It is to be installed so that the drainage collecting hole formed in the drainage sheet longitudinal direction toward the strata, or install a side without the drainage collecting hole adjacent to the wall of the structure to be used as a waterproof membrane to block water from the soil into the structure wall, On the other hand it relates to a strap drainage with a reinforcing member to strengthen the resistance to soil pressure.

On the other hand, its improved invention, US 6,247,874 B1 and the disclosed drainage straps also have a small diameter drainage collecting hole and groove formed in the longitudinal direction of the thin strap drainage and provided densely on the surface thereof. In order to overcome the disadvantage that the strap is not easy to produce and the pull resistance in the width direction is easily broken, the horizontal and vertical or overlapping fiber or steel short fibers are embedded in the strap body, and the drain collecting hole In order to apply a large tensile strength to the surface without the water, a drainage strap material having a straight or curved transverse rib and overlapping portions in the width direction has been proposed.

By forming a narrow cleavage groove of the small diameter drain collecting holes extending in the longitudinal direction and provided densely on the surface thereof, by forming various ribs on the surface containing short fibers and no drain collecting hole, Expect the effect of increasing tensile strength and reducing slippage, but the strap drainage material with short ribs and various ribs on the back side with narrow grooves and holes on one side of the sheet-shaped material in the continuous length direction There is still a problem that is not easy to high-speed production in the longitudinal direction.

 In addition, when a siphonic force is generated through a hole in which the slit portion is clogged by the surface tension of water penetrating into the longitudinal slit-shaped groove by the capillary action, the slit-shaped groove is drained by vacuum. The suction force is generated only when it is maintained, but due to the surface tension of the water, the slit-shaped area cannot be completely blocked. will be.

The object of the present invention is very excellent in high-speed productivity in the continuous length direction, unlike the drainage plate or drainage straps as described above, to eliminate the concern that the drainage passages are blocked due to the pressure of the soil, in particular the blockage of the slit portion drainage holes It solves the problem that the vacuum in the drain hole is not effectively formed only by the surface tension of the water, and the high suction force is not generated, and the drainage by the perfect siphon phenomenon is induced, and the slope of the road, tunnel, farmland, golf field, general building construction It is to provide a novel drainage sheet made of a flexible, thin and weather-resistant thermoplastic synthetic resin used for underground irrigation and drainage and drainage method using the same.

Accordingly, in the present invention, a flexible and weather-resistant thermoplastic synthetic resin is formed with a supporting piers 121 having a height of 9 mm and a width of 1.5 mm in the width direction of the continuous length direction, and having a width of 2 mm and a width of 7.5 mm in the longitudinal direction of the supporting piers. The siphon liquid 122 having a radius of 0.5 mm and a width of 1.5 mm and a height of 8.5 mm having a radius of 1 mm to form a round drainage passage 10 has a bottom radius of 1 mm round in a width direction of 5.5 mm in the continuous length direction and width 5.5 A seat body 120 having a predetermined width repeated left and right continuously based on a middle width of the water collecting passage 30 formed to have a depth of 2.5 mm; a continuous length on each support piers 121 in a continuous length direction of the seat body 120. A width of 1.5 mm in width and a groove of 4.5 mm in depth are formed in both sides of the support piers slot 111 having a width of 1.5 mm and a height of 5.5 mm at the bottom of the width 11.5 mm in the direction. Depth of 2.5 mm so that grooves are formed, width 1 mm A siphon cover 110 having a siphon collar 112 having a height of 3.5 mm in a round diameter of 1 mm is integrally formed, and is selectively assembled by a high frequency adhesive or adhesive bonded to a groove formed in both sides of the support pier slot 111. It is to provide a sheet and a drainage method using the same.

Drain sheet 100 according to the present invention is a novel drainage sheet made of a flexible, thin and weather-resistant thermoplastic synthetic resin, unlike the general drainage plate or drainage straps to be used as a seat body and a siphon cover, high productivity in a continuous length direction It is excellent and the siphon cover is assembled on the seat body, which eliminates the fear that drainage passages are blocked due to the pressure of the soil. Especially, the vacuum in the drainage hole is not effectively formed by the conventional surface tension. In order to solve the problem that is not solved, it has the effect of inducing the drainage of leachate with the suction force according to the perfect siphon phenomenon by the siphon slit that the vacuum is formed by the water level formed by the seat body and the siphon cover (water level). Cut slope, tunnel, farmland, golf course, general building construction of various roads It relates to a novel useful drainage sheet and drainage method using the same for use in underground irrigation and drainage method.
