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

In the case of large-scale buildings such as apartments, the underground parking lot has become legally required recently. Due to the increase in the number of residents and the desire to secure the green space of tenants, the underground parking lot of the apartment is located in a lower area, The influence of positive pressure on buildings is getting bigger. Therefore, an anchor method and a dewatering method are used to prevent the positive pressure due to the water level change of the groundwater from affecting the building structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a drainage clog detection apparatus of a groundwater drainage apparatus according to the present invention will be described in detail with reference to the embodiments shown in the drawings.

1 and 2 show an apparatus 200 for detecting drainage clogging of a groundwater drainage apparatus according to the present invention.

Referring to the drawings, a clogging detection device 200 for a drainage part of a groundwater drainage device detects clogging of a drainage part installed in an underground ground of a building to collect groundwater. At this time, the groundwater drainage apparatus 110 includes a drainage unit 22 such as a pipe or a drainage pipe 21 through which groundwater flows into a lower portion of a foundation concrete installed in an underground ground of a building structure, A main discharge part 40 connected to the water discharge pipe 20 and having an upper end maintained at a design stabilized water level to discharge the ground water to the outside, And an auxiliary discharging portion (50) for discharging the groundwater by maintaining the upper portion at a height lower than the designed stable water level.

At this time, the drainage section 22 is not limited to the illustrated example but may be structured according to the ground on which the building or structure is installed. In the case of the soft ground, the drainage section 22 is surrounded by a nonwoven fabric, The purifier pipes communicated with the crystal 25 and the water pipes or drain plates may be provided on the pipes. The ground water collected by the pipes may be discharged to the collector 25. In the case of the rock bedrock, a nonwoven fabric and drainage plates for collecting groundwater, and a discharge pipe for discharging the collected groundwater to the collector 25 may be provided.

The main discharge portion 40 is connected to the drain pipe 20 and has a first extension pipe 41 extending to the wall side of the building and a second extension pipe 41 connected to the first extension pipe 41, A straight pipe 42 and a drainage container 43 installed on the wall side of the building and having a receiving space 45 therein so that the first straight pipe 42 can be received.

The first extension pipe 41 is formed of a pipe having a flow path for allowing groundwater to flow therein, and is connected to the drain pipe 20 at one end.

The first linear straight pipe 42 is connected to the other end of the first extension pipe 41 and extends upward, and is extended to a height corresponding to the designed stable water. In this case, when the water level of the groundwater exceeds the designed stable water level, the first linear straight pipe 42 is preferably provided with the first discharge port 44 at the upper end thereof so that the groundwater can flow over the ground.

In the illustrated embodiment, three first linear straight pipes 42 are provided. However, the number of the first linear straight pipes 42 is not limited to the illustrated example. have.

The drainage container 43 is installed on the wall side of the building and is formed as a hexahedron structure in which an internal space is provided so that the first straight pipe 42 can be received therein. A downflow water induction hole 46 is formed on the lower outer circumferential surface of the drain container 43 so that the groundwater flowing from the first straight pipe 42 to the inside of the drain container 43 can be discharged to the outside.

When a relatively large amount of rain is applied and the water level of the groundwater becomes higher than the design stable water level, the groundwater flows into the drain pipe 20 through the drainage part 22. The groundwater flowing into the drain pipe 20 flows into the first extension pipe 41 and the groundwater flowing through the first extension pipe 41 flows into the first linear pipe 42. At this time, the first linear straight pipe 42 has a first discharge port 44 formed at a height corresponding to the designed water of the ground water, so that the ground water flows into the drain container 43 and flows into the drain container 43. Since the groundwater contained in the drainage container 43 is discharged to the outside through the overflow water induction hole 46, the groundwater around the building maintains the design stable water level.

If the drainage container 43 is not provided with the overflow water induction hole 46, the groundwater discharged through the first linear straight pipe 42 is not discharged to the outside, If the water level is exceeded, the structure may be damaged by the positive pressure due to the difference of groundwater level between the bottom of the building and the underground outer wall. The underground drainage control apparatus according to the present invention prevents the groundwater level from exceeding the design stability level because the groundwater level is discharged to the outside of the drainage vessel 43 through the overflow water induction hole 46 before the level of the groundwater exceeds the design stability level.

The drainage clog detector 200 of the groundwater drainage apparatus according to the present invention will be described in detail as follows.

The drainage clog detector 200 of the groundwater drainage apparatus includes a plurality of fillers 211 filled in an installation hole 212 formed in an underground ground of a building and a plurality of fillers 211 embedded in the fillets 211, A protection unit 230 for protecting the signal transmission line 221 of the gap pressure gauge 220 and a protection unit 230 installed in the gap pressure gauge 220.

The pore pressure gauge 220 is a vibrating horn pressure gauge that converts hydraulic pressure into a vibration signal by a diaphragm and a vibration coil and an electromagnetic coil which are tightly fixed to one side of the diaphragm. That is, since the diaphragm is sealed at one end to form a pressure transducer, the diaphragm is deformed in response to a change in pressure, and the tension of the diaphragm changes accordingly. Since the inherent free vibration frequency varies depending on the tension, the free vibration frequency of the vibration vibration is changed by the change in the tension of the vibration vibration. Therefore, the diaphragm is deformed by the pressure change, and the tension of the vibration is changed, and the vibration has a different natural frequency depending on the tension. Therefore, when the natural frequency of the vibration is read, the pressure can be known. The signal transmission line 221 of the pore pressure gauge 220 is exposed to the outside of the installation hole 212 and supported by the protection unit 230 and has a terminal 222 for connection to the detection unit 270 ).
