Description

A drainage promotion apparatus of subsurface water and its construction method

The present invention relates to a groundwater drainage promotion device and a construction method thereof, and more particularly, in the groundwater drainage pipe in the lower basement such as landfills, infiltration prevention holes, waterways, culverts, etc. There is no restriction on the number of pipes, so it can be easily piped into one pipe without connecting multiple pipes.The filter cloth is covered on the outside of the pipe, so that each pipe is laminated with gravel and then covered with a non-woven fabric to prevent foreign substances from entering the pipe. The present invention relates to a groundwater drainage promotion device and a construction method thereof, which can solve the inconvenience of construction and reduce the material cost and loss of manpower and equipment caused by the purchase of aggregates.

In general, in order to prevent ground subsidence in the ground below the structures such as landfills, in order to prevent ground subsidence, the groundwater collection main and branch pipes are installed more widely than the superstructure, and the groundwater is collected and drained. Much research has been done on the structure and connection of pipe connections.

For example, the groundwater drainage pipe installed in the basement of the waste landfill will be described with reference to the structure of the groundwater drainage pipe installed in the conventional underground. As shown in FIGS. 1, 2 and 3, the lower part of the waste landfill 1 surrounded by the water barrier wall 2 is shown. In order to prevent subsidence in the basement, the groundwater collecting main pipe 3 is piped across the center of the landfill 1 and wider than the size of the landfill, and a plurality of the groundwater collecting main pipes 3 are arranged and coupled to both sides of the groundwater collecting main pipe 3. The hole hole 4 which perforated the several hole extended by 8) is embedded. When embedding the perforated pipe (4) pipe excavated the ground to the depth of the radius of the pipe and then pipe the pipe and if the length of the buried length is connected by connecting a plurality of perforated pipe (4) through the connection formed at the end of the pipe Later, the gravel 14 is stacked on top, and the gravel 14 is covered with a nonwoven fabric 6 and then completely embedded in soil, clay, or the like.

In the conventional groundwater drainage pipe embedding method as described above, when the length of the pipe of the perforated pipe 4 becomes longer, the plurality of pipes are connected through the coupling of the connection part 8, and the connection method by the connection part 8 is the connection part 8. The connection part 8 is easily crushed by a load acting on the cuff, and leakage occurs. Also, when the perforated tube 4 is buried, the gravel 14 is laminated on the upper part of the tube and the nonwoven fabric 6 is covered on the gravel 14. By laying the pipe, the method of laying is cumbersome, the material cost is high due to the purchase of aggregate, and the cost of construction is high due to the high consumption of manpower and equipment.

The present invention is created to solve the conventional problems as described above, buried underground water collecting main pipe in the lower basement of the structure, a plurality of pipes are coupled to both sides of the ground water collecting main pipe and spiral wrinkles formed on the outer surface It consists of a spiral corrugated perforated tube coated with a filter cloth on the outside to absorb ground water, and the spiral corrugated perforated tube has no limitation on the length of the buried length of the tube. The purpose of the present invention is to provide a groundwater drainage facilitating device and a construction method thereof in which the pipe can be easily buried and there is no connection part in the pipe so that no leakage occurs due to the crushing of the connection part.

The present invention for achieving the above object is connected to both sides of the groundwater collecting pipe and the groundwater collecting pipe which is buried with a certain depth in the lower basement of the structure, spirally corrugated perforated pipe is piped wider than the size of the upper structure at regular intervals It is to provide a groundwater drainage promoting device and a construction method thereof.

Figure 4 is a perspective view and a side view of the spiral pleated perforated tube of the present invention, the spiral pleated perforated tube 5 is formed on the outer surface of the spiral pleat at regular intervals, the hole of a predetermined size so that water is absorbed therebetween The filter cloth 9 is coated on the outside.

The filter cloth (9) coated on the outer side of the spiral pleated perforated tube (5) prevents soil or other foreign matter from flowing into the tube after the tube is buried, and the soil or other foreign matter is sucked in the pipe is not coated with a conventional filter cloth In order to prevent it from being stacked, the spiral corrugated perforated pipe 5 may be stacked along the non-woven fabric 6 and then covered with a non-woven fabric 6 and then buried. It is easy to bury the pipe because the pipe is buried to earth and sand after the required length.

In addition, the spiral corrugated perforated tube (5) has no restriction on the embedding length of the tube, so if the length of the embedding is long, there is a restriction on the embedding length of the tube. By cutting the pipe to the required length differently, there is no work to be connected through the connection part 8, which simplifies the piping work, and leaks due to twisting or damage of the connection part 8 generated by the load acting on the connection part 8. Does not occur.
