Description

Drainage system protecting inundation and flowing backward to building}

The present invention is to prevent the rainwater or various sewage flow into the space located lower than the road in the rainy season, such as rainy season, more specifically, flooded by blocking the rainwater or sewage flowing from the outside to enter the room through the door The present invention relates to a structure for preventing flood damage of a building that minimizes damage and prevents flooding in the building and prevents backflow of drainage.

Many rainfall concentrations in certain periods, including Korea, are accompanied by flood damage. In particular, in the space located lower than the ground, a large amount of rainwater and sewage that cannot be accommodated by the public drainage system is introduced into the room, and the damage caused by flooding is increased.

In order to prevent such damages, the government is trying to expand public drainage facilities to increase the amount of drainage. However, these expansion projects are not easy to proceed due to the high initial cost, and their effectiveness cannot be expected.

As a result, only the houses in the flooded areas are flooded every year.

In order to solve such a problem, the waterproof panel, which is conventionally arranged to be Shanghai-dong before the door, is lifted up and down according to the rainwater level in the sump communicating with the drain pipe for drainage, and according to the quantity without a separate sensor, A facility structure has been proposed to flexibly block rainwater flowing into the water.

That is, when rainwater flows into the sump, the water level of the collected rainwater increases and the buoyancy is applied to the waterproof panel. When the buoyancy has sufficient force to overcome the load of the waterproof panel, the waterproof panel moves upwards from then on. While blocking the door.

By the way, in the case of the conventional installation structure, even though the amount of rainwater collected in the sump is not dangerous enough to flow into the interior, the movement of the occupant through the indoor and outdoor was prevented while the waterproof panel was moved upward. This disturbance hindered the activities of residents who had to move hurriedly for flood preparation, resulting in the avoidance of the installation despite the advantages of the conventional facility structure.

Therefore, the present invention was devised to solve the above problems, to prevent the flooding of rainwater and sewage flowing into the door to the room located somewhat lower from the ground, and to prevent the indoor flooding by smoothly draining the rainwater and sewage An object of the present invention is to provide a structure for preventing flood damage of a building to prevent flooding of the building and backflow of drainage.

Flood control facility structure 100 according to the present invention, the door 110 having a door frame 112; A guide groove 140 embedded in the front underground of the door 110; Inserted into the upper surface of the guide groove 140 is fixed to be movable up and down and form a flat plate with a sufficient area covering the door 110, the front so that the sewage flowing from the ground flows into the guide groove 142 A waterproof panel 120 having a main body 126 having the cut drain groove 124 and a buoyancy member 122 provided at a lower end of the main body 126; A water collecting tank 150 communicating with the guide groove 140, the lower end of the guide groove 140 communicating through an inlet 151 disposed at a predetermined height from a bottom thereof; A drain pipe 160 connected to a lower end of the sump tank 150 lower than a position of the inlet 151 to drain sewage collected in the sump tank 150 to the outside; And a fixing frame 171 (see FIG. 4) having a plurality of drain holes 172 (see FIG. 4) partitioned by a partition wall 175 (see FIG. 4) and fixed to a predetermined position in the drain pipe 160. In the hole 172 is rotatably fixed via the rotation axis (174a (see Fig. 4)) to be an opening and closing door (174 (see Fig. 4)) to open and close the drain hole 172 in accordance with the flow of water, the opening and closing door 174 is a diaphragm 174c (see FIG. 4) for sealing the drain hole 172 so that only the sewage drained from the water collecting tank 150 can pass through the drain hole 172 and one of the diaphragm 174c. Flood protection facility structure of the building including a water gate (170; Fig. 4) consisting of a stopper (174b) protruding vertically in the side portion and abutting the partition wall 175 so that the opening and closing door 174 is rotated only in one direction. In one side of the main body 126 in contact with the inner surface of the guide groove 142 Is coated with a friction surface 121 of a material having a predetermined coefficient of friction; The body 126 and the buoyancy member 122 is disposed between the body 126 and the buoyancy member 122 further includes a carbo body 125 to mutually support the carb, the carb body 125, the Only part of the main body 126 is compressed to be extruded by the additional external force, and the elastic force is further interlocked with the external force added due to the increase in the buoyancy force that the buoyancy member 122 receives. It characterized in that it has a carbohydrate coefficient to cause the main body 126 to rise immediately in excess of the maximum stop friction formed between the inner surface of the friction surface 121 and the guide groove 142.

Indoor flooding due to torrential heavy rain occurs mainly through the entrance door (hereinafter door). However, closing the door 110 using a separate driving device each time there is a heavy rain will be economical in terms of installation and management.

To this end, the drainage system 100 according to the present invention prevents indoor infiltration of sewage using the waterproof panel 120 which is elevated by buoyancy according to the amount of sewage blown by the heavy rain.

The waterproof panel 120 is inserted into the guide groove body 140 having the guide groove 142 having an upper surface thereof moved up and down along the guide groove 142. In addition, the guide groove 140 is disposed in front of the door 110 to prevent the inundation while moving upward from the bottom of the door (110).

On the other hand, in order to prevent the sewage into the gap between the waterproof panel 120 and the door 110, a pair of fixed rails (112a) in the longitudinal direction on both sides of the door frame 112 constituting the door 110 ) Is formed, and the rail-type fixing protrusion 123 is formed at both edges of the rear surface of the waterproof panel 120 accordingly. Therefore, the rail-type fixing protrusion 123 is engaged with the fixing rail 112a to guide the lifting and lowering of the waterproof panel 120, and sewage gaps generated between the waterproof panel 120 and the door frame 112 are sewage. To prevent penetration.

In addition, the front of the waterproof panel 120 is formed with a drain groove 124 cut to a predetermined size, the rainwater generated on the ground through the space surrounded by the inner wall of the drain groove 124 and the guide groove 140 and Drain the sewage. Meanwhile, a water collecting tank 150 having a predetermined volume is embedded in front of the door 110, and the water collecting tank 150 communicates with the guide groove 141 and the inlet 151. At this time, the inlet 151 is located at a certain height from the bottom of the sump (150). In addition, the inlet 151 is located at the lower end of the guide groove 141.

As a result, the rainwater and sewage generated on the ground flows into the guide groove 142 through the drain groove 124 of the waterproof panel 120, and is collected in the water collecting tank 150 via the inlet 151.

Subsequently, the bottom of the waterproof panel 120 further includes a buoyancy member 122. The buoyancy member 122 is made of a material and structure having a sufficient buoyancy to support the load of the waterproof panel 120.

However, the conventional buoyancy member 122 is integrated with the main body 126 excluding the buoyancy member 122 in the waterproof panel 120, and is immediately elevated according to the level of rainwater collected in the sump 150. To this end, the present invention further includes a carbohydrate 125 disposed between the buoyancy member 122 and the main body 126 to support the buoyancy member 122 and the main body 126.

The carcass 125 is basically compressed by the load of the main body 126. At this time, the carcass 125 is not completely compressed by the load of the main body 126 has a modulus of elasticity that only a portion thereof is compressed, and has a margin that can be further compressed by an external force added later.

On the other hand, the friction surface 121 is applied to one surface of the main body 126 to be engaged with the inner surface in the guide groove 142, thereby preventing the upward movement of the waterproof panel 120. At this time, the maximum static frictional force of the frictional surface of the friction surface 121 has a size such that the body 126 can not be pushed up even with the force of the elastic body 125 compressed with the load of the body 126. .

Therefore, in the situation where the buoyancy member 122 is not subjected to an external force, the carbide body 125 supports the main body 126 while maintaining a compressed state by a predetermined length.

Thereafter, when the water level of the sump tank 150 increases to lock the buoyancy member 122, the buoyancy received by the buoyancy member 122 increases, and as a result, the buoyancy member 122 exerts upward force. do. The applied force is transmitted to the carcass 125 and further compresses the carcass 125.

However, even when the elastic body 125 is further compressed, the elastic force does not exceed the maximum static frictional force of the main body 126 so that the main body 126 maintains its current position. However, the buoyancy force continuously applied and the elasticity force due to the compression of the elastic body 125 cause the rapid movement of the body 126 while exceeding the maximum static frictional force of the body 126.

That is, the main body 126 quickly rises only above a certain water level, so that the main body 126 is practically used only in a situation where the waterproof panel 120 is required, and in other cases, the main body 126 is not operated so as not to cause inconvenience in traffic.

On the other hand, in the pollution prevention facility structure 100 according to the present invention, a guide roller 180 for smoothly moving upward of the waterproof panel 120 is further included. The guide roller 180 has a roller 181 that is engaged with one surface of the main body 126 to enable a smooth movement during instantaneous upward movement of the waterproof panel 120, and additionally the external force received by the roller 181 A shock absorbing member 182 is further included.

On the other hand, the roller 181 and the buffer member 182 may be provided with a plurality, a fixing body 183 for fixing them collectively may be further included. The fixing body 183 may be engaged with the fitting groove 141 formed on the inner surface of the guide groove 142 to achieve the fixing of the guide roller 180.

If the guide roller 180 is further included, there is a fear that the maximum stop friction of the waterproof panel 120 required by the present invention is greatly reduced. Accordingly, a stopper 143 is further included to block the operation of the waterproof panel 120 in place of the reduced maximum stop friction.

The stopper 143 is disposed at the opening of the guide groove 142 and protrudes inward. In addition, the stopper 143 is a flexible elastic material that is not easily bent under an external force of a predetermined size.

Correspondingly, a stop groove 127 is further formed at an upper end of the main body 126 to engage the stopper 143. Therefore, the stopper 143 is inserted into the locking groove 127 to stop the movement of the entire waterproof panel 120. Subsequently, when the elasticity of the carcass 125 is increased, the stopper 143 may not be able to withstand the pressure of the waterproof panel 120 which is weighted, thereby allowing upward movement of the waterproof panel 120.

Since the inlet 151 communicating with the guide groove 141 and the sump tank 150 is located at a predetermined height from the bottom of the sump tank 150, the rainwater and the sewage drained through the drainage groove 124 and then the inlet port. 151 flows directly into the sump 150. However, since the bottom of the sump tank 150 is located at a lower position than the inlet 151, sewage water may not flow back until the sump tank 150 is full. Therefore, the waterproof panel 120 is not lifted due to the average rainfall. On the other hand, when the rainwater and sewage drained to the sump tank 150 due to the heavy rain to increase the water level of the rainwater and sewage collected in the sump tank 150 to the guide groove 141 through the inlet 151 Rainwater and sewage are also introduced. Rainwater and sewage introduced in this way affects the buoyancy member 122 to apply buoyancy to the waterproof panel 120, through which the waterproof panel 120 is moved upward. In addition, when the rainfall and the level of rainwater and sewage in the sump tank 150 increases, the water level in the guide groove 141 is also increased to raise the lifting height of the buoyancy member 122.

On the other hand, rain and sewage collected in the sump 150 is drained to the external public drainage facility through the drain pipe 160 located at the lower end of the sump (150).

Figure 4 is an exploded perspective view showing the appearance of the water gate according to the present invention, Figure 5 is a view showing the operation of the water gate according to the present invention will be described with reference to this.

Since the drain pipe 160 communicates with the sump tank 150 and the external public drainage system, when the sewage is not able to accommodate the sewage supplied by the public drainage system due to high rainfall, the sewage sump 150 is provided through the drainage pipe 160. Can be reversed. In order to prevent this, the drain pipe 160 further includes a sluice gate 170. The sluice gate 170 is composed of a fixed frame 171 having a plurality of drain holes 172 through which the sewage passes, and an opening / closing door 174 that opens and closes the drain holes 172. Has a powerful opening and closing structure. That is, the opening / closing door 174 opens and closes via the rotation shaft 174a which is located to be biased on the upper and lower surfaces of the opening / closing door 174. However, the opening and closing door 174 is opened only by the hydraulic power of the sewage drained from the water collecting tank 150, and the drainage hole 172 is closed in the reverse direction. To this end, the opening and closing door 174 protrudes perpendicularly to the diaphragm 174c blocking the drainage hole 172 and the stopper 175 to be engaged with the partition wall 175 partitioning the drainage hole 172. (174b). That is, as shown in Figure 5, when the sewage is discharged from the water collecting tank 150, the opening and closing door 174 is rotated without difficulty to open the drain hole 172 (Fig. A), the sewage flows in the reverse direction In this case, the opening / closing door 174 rotates with force and closes the drain hole 172 while the stopper 174b is engaged with the partition wall 175 so as not to rotate toward the water collecting tank 150.

As a result, the sluice gate 170 reversely proceeds toward the sump tank 150 along the sewage and rainwater drainage pipes 160, which are not handled by the public drainage system, to solve the problem of reducing the drainage amount of the sump tank 150. do.

Unexplained withdrawal reference numeral '173' is a rotating shaft fixing hole, which is engaged with the rotating shaft 174a of the opening / closing door 174 so that the opening / closing door 174 is rotatably coupled with the fixing frame 171.

According to the present invention as described above, a waterproof panel which is elevated according to precipitation is installed on the door which is the main path of rainwater and sewage which causes indoor flooding during heavy rains, thereby preventing the inflow of rainwater and sewage indoors, and the waterproof panel Since there is no need to install a separate drive mechanism for the lifting, the burden on the installation and management costs can be minimized.

In addition, since the operation of the waterproof panel is made only above a certain level without additional equipment, the waterproof panel is moved up to a safe level to solve the problem of obstructing the traffic of residents and more flexible utilization is possible.
