Description

Underground ater drainage apparatus with filter cleaner

The present invention relates to groundwater drainage, and more particularly to groundwater drainage having a filter cleaning unit for cleaning the filter surrounding the drain pipe.

In general, when the final floor of the building structure is installed below the groundwater level, the positive pressure (buoyancy) is generated by the difference between the space excluded by the building, that is, the groundwater head difference between the floor of the building structure and the basement outer wall of the building structure. This positive pressure acts as a reaction against the weight of the building, which may damage the building structure, so it is necessary to adjust the groundwater level.

In particular, when constructing a large-scale building such as an apartment, underground parking is mandatory by law, and the underground parking lot of an apartment is located in a lower area due to the increasing trend of occupants and the desire to secure a green space. The effect of positive pressure on buildings is growing. Therefore, in order to prevent the positive pressure according to the variable groundwater level affects the building structure, the Permanent Anchor method and the Dewatering method are used.

As an example of the drainage method, Korean Patent Registration No. 317530 discloses a positive pressure relief system for underground structures, and Utility Model No. 0195274 discloses a vertical drainage pipe for preventing buoyancy of underground buildings. The disclosed buoyancy preventing vertical drain pipe is formed with a drain hole in the base slide bottom.

6 and 7 show another embodiment of the groundwater drainage apparatus according to the present invention. Here, the same reference numerals as the above-described embodiment indicate the same components.

Referring to the drawings, the groundwater drainage device is connected to the inside of the hold drainboard 25 wrapped by the perforated pipe 21 or the filter 30 wrapped by a filter for collecting groundwater, and therefrom, the base concrete layer 200 It passes through the), it is provided with a washing pipe 40 for inserting a nozzle for injecting high-pressure washing water for cleaning the filter or for supplying the washing water of high pressure. And it is connected to the side of the washing tube 40 and has a horizontal connecting pipe 51, the first connecting pipe 52 is connected to the horizontal connecting pipe 51 and introduced or exposed to the wall of the building. In addition, the second vertical pipe 53 may be vertically installed on the inner wall of the building in parallel with the first vertical pipe 52 as shown in FIG. 1, which is installed at a portion adjacent to the water collecting well 100. The first vertical pipe 52 and the second vertical pipe 53 are connected to each other by the communication pipe 54 to communicate with each other. The communication pipe 54 communicating the first and second vertical pipes 52 and 53 is installed at a position relatively lower than the design stability level of the groundwater or the height of the first and second vertical pipes 52 and 53. Can be. One of the first and second vertical pipes 52 and 53 may have a height higher than the design safety level of the groundwater. And the end of the washing tube 40 is a cap 45 is installed. The vertical pipe is not limited to the above-described embodiment, and any structure can be used as long as the groundwater can be discharged when the level of the groundwater is higher than the design safety level.

On the side adjacent to the drainage portion, a detection tube 70 for detecting a blockage of the filter therefrom may be installed at a height of the design safety head on the side adjacent to the water permeable layer 61 made of sand or the like surrounding the drainage portion.

The detection tube 70 is blocked by the fine grain of the filter 30 constituting the drainage portion 20, that is, the groundwater into which the filter is introduced, by using the water level or pressure of the groundwater to discharge sufficient groundwater. If not, it is possible to detect whether the filter 30 is blocked by allowing the ground water to be discharged through the detection tube (70).

Referring to the operation of the groundwater drainage device having a filter cleaning unit according to the present invention configured as described above are as follows.

The groundwater drainage device is discharged from the groundwater to the sump 100 through the drainage portion 20 formed by a hold drainboard and a filter 30 surrounding the groundwater or a perforated pipe 21 wrapped by the filter when the groundwater level rises. Groundwater levels will be maintained at or below the design safety level. In particular, when the groundwater is sufficiently discharged through the drainage part 20, groundwater is overflowed through the first and second vertical pipes 52 and 53, and there is no vertical pipe in the case of the permanent drainage device, thereby maintaining the groundwater level.

In this process, when the filter 30 is clogged by the fine particles moving on the ground when the groundwater is discharged, the groundwater is not discharged smoothly, and the head of the groundwater rises above the design safety level. In this case, since the nonwoven fabric which is the filter 30 is clogged, the overflow does not occur through the vertical pipe 53. When the groundwater is not discharged sufficiently as described above, the groundwater level rises, and the groundwater flows out through the detection tube 70. Therefore, when the groundwater is discharged through the detection tube 70, it can be seen that the filter 30 is blocked by the fine particles so that the groundwater is not discharged smoothly. Accordingly, the installation position of the detection pipe is preferably installed in the management area of the manager at all times.

As described above, when the filter is blocked in the detection tube 70 as described above, the cap 45 and the water discharge member 41 are separated from the washing tube 40, and the nozzle 301 of the filter washing means 300 is removed. Is inserted through the washing tube (40). Then, the high pressure washing water is sprayed through the nozzle 301 to back the filter 30 surrounding the oil hole tube 21 or the hold drain board 25.

 When backwashing the filter 30 by supplying the high pressure washing water to the drain, the valve 11a is discharged to discharge the groundwater to the sump 100, and the washing water is pumped by the washing tube 40 and the pump. Connect the pipe. And the pump 302 is used to pump the washing water at high pressure.

In this case, the washing water is introduced into the drainage portion 20 formed of the perforated pipe 21 or the hold drain board 25 through the washing pipe 40, and the washing water is discharged through the filter to the water permeable layer 61 to backwash the filter. . Thus, the fine particles blocking the filter are removed.

As described above, when the groundwater drainage device having the filter cleaning part is identified by a fine particle piggybacked on the groundwater to be drained, the filter may be cleaned through the cleaning pipe, thereby preventing the building from being damaged by the positive pressure of the groundwater. It can prevent.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
