It includes a hydrologic platform 200 including a water gate 230 to elevate up and down while partially blocking the sewage (S).

The base 100 includes a receiving groove 110 of a volume capable of accommodating sludge contained in the sewage S, directly below and below the opening passage 12, and detachable to the receiving groove 110. The sediment receiving container 120 is securely disposed. On the other hand, the bottom surface of the deposit receiving container 120 has its center protruded upwards so that a groove is formed at the bottom edge. This will be described in more detail below.

The sluice platform 200 is a sewer (S) flowing along the drain pipe 20 is partially blocked before passing through the receiving groove 110, blocking the sluice 230 to lift, if necessary, the sluice gate 230 By controlling the opening and closing of the), the elevation of the water gate 230 uses the buoyancy of the sewage (S).

To this end, the hydrologic lifting platform 200 is buoyant members (220, 220 ') that is buoyant to be seated on the surface of the sewage (S) and the support (240, 240' connected to the buoyancy members 220, 220 ') ), First and second guide bars 211, 212, 211 ', and 212' that are connected upwardly of the supports 240 and 240 ', and a water gate connected to ends of the supports 240 and 240'. 230.

Here, all of the components of the sluice platform 200 is provided except for the sluice gate 230, and as shown in Figure 2, are disposed on both sides of the drain pipe 20, respectively. This is to minimize the interference of the components in the flow of the sewage (S) flowing along the drain pipe 20, the sewage (S) is introduced between the buoyancy member (220, 220 ') while the manhole according to the present invention The structure of the sewage (S) will not interfere significantly with the flow. In addition, the buoyancy member 220 is preferably manufactured in a streamlined type to minimize the resistance to running water.

On the other hand, the buoyancy member 220 is made of a material to receive the maximum influence of the buoyancy, it may be manufactured in a hollow cylindrical shape.

The first and second guide bars 211, 212, 211 ′, and 212 ′ are formed on an upper surface of the supporters 240 and 240 ′ which are horizontally disposed along the pipe direction of the drain pipe 20, and the buoyancy member. Shanghai dong buoyancy of (220, 220 ') is formed to be smooth. Subsequently, first and second guide lines 251, 252, 251 ′ and 252 ′ into which the first and second guide bars 211, 212, 211 ′ and 212 ′ are inserted are respectively disposed on the upper surface of the drain pipe 20. Is placed.

That is, the first and second guide bars 211, 212, 211 ′, and 212 ′ are engaged with the first and second guide lines 251, 252, 251 ′, and 252 ′, and continuously maintain the force of the sewage S. Fixing the buoyancy member 220 in place, and also, as the buoyancy member 220 is elevated in accordance with the water level change of the sewage (S) serves as a guide to guide the lifting direction.

At this time, the buoyancy member 220 and the water gate 230 is fixed to both ends of the support (240, 240 '), respectively, so that the first and second guides for stable fixing without shaking even the flow of the sewage (S) Bars 211, 212, 211 ′, 212 ′ and first and second guide lines 251, 252, 251 ′, and 252 ′ may be provided at least two.

The water gate 230 is fixed between the pair of ends of the supports 240 and 240 '.

The sluice gate 230 is disposed in front of the receiving groove 110, and adjusts the amount of passage of the base 100 of the sewage (S) flowing along the drain pipe 20, a plurality of engaging bars (as shown) 231 is arranged to be spaced apart at regular intervals to filter the sludge flowing due to the structure having a plurality of water passage grooves (232).

3 and 4 is a partial cross-sectional view schematically showing the operation of the hydrologic platform according to the present invention, will be described with reference to this.

As described above, the water gate 230 drains a certain amount of sewage (S) through the water passage groove 232, and the sludge (T) that cannot pass through the water passage groove 232 is filtered through the water gate 230 By depositing in front of the, the flow of sewage (S) including sludge (T) is blocked. At this time, the base 100 into which the water gate 230 is inserted so as to increase the deposition amount of the sludge T and then smoothly move the deposited sludge T by the force of the sewage S that is drained all at once. The upper surface of the inclined surface 140 to be inclined toward the receiving groove 110.

In addition, when the water level of the sewage (S) is within a certain height, so that the water gate 230 continuously performs the filtering function, even if the buoyancy member 220 goes up to the predetermined height so that the water gate 230 does not open. do. To this end, an insertion tube 130 into which the lower end of the sluice gate 230 is inserted to a predetermined depth is disposed in the inclined surface 140.

As shown in FIG. 3, the sewage S in the drain 20 is blocked by the continuous flow by the water gate 230. Therefore, sludge (T) included in the sewage (S) is also pushed up to the front of the water gate 230 is stagnant, eventually flowing along the inclined surface 140 is deposited on the front of the water gate 230.

The sludge (T) deposited in this way continuously increases the level of the sewage (S) while disturbing the flow of the sewage (S). As a result, the buoyancy member 220 is moved upward due to the sewage (S) that the water level is increased, the water gate 230 also moves upward. Therefore, the sewage S stagnated in front of the water gate 230 is drained through the water gate 230 while temporarily moving to a high water pressure, and the sludge T deposited on the inclined surface 140 moves. Sweep along the sewage (S).

At this time, when a large amount of sewage (S) is drained through the water gate 230 opened, the force hits the deposit receiving container 120 in the receiving groove (110). That is, the sludge deposited in the deposit container 120 may be separated from the deposit container 120 while spawning by a sudden impact.

Therefore, as described above, the deposit receiving container 120 according to the present invention has a shape in which a center protrudes and a groove is formed so that the sludge deposited into the deposit receiving container 120 is integrated at an edge, and a substantial impact. In the center of this application, the number of sludges should be reduced as much as possible. In addition, in order to minimize the detachment of the sludge due to a sudden impact, the front wall 122 adjacent to the water gate 230 in the deposit container 120 and the rear wall 123 facing the front wall 122. Put the difference in height. That is, the height of the rear wall 123 is higher than the front wall 122 to prevent the sludge deposited in the deposit receiving container 120.

Sediment containing container 120 having such a shape can be attached and detached from the base 100, when a certain amount of sludge (T) is collected in the deposit containing container 120 to lift and collect the deposit containing container 120. By collectively removing the sludge (T), and seating it again on the receiving groove 110 of the base 100, it is possible to efficiently remove the sludge in the manhole.

Figure 5 is a cross-sectional view showing the operation of the insertion tube according to the present invention, will be described with reference to this.

As described above, the sluice gate 230 should always be closed to prevent movement of the sewage S when the sewage S is within a certain level. Thus, in the manhole 10 according to the present invention for this purpose by placing the insertion tube 130 on the base 100, the lower portion of the water gate 230 can be maintained in the inserted state in the insertion tube 130 Make sure

However, the insertion tube 130 may also be stacked into a groove having a depth, such that the lower portion of the water gate 230 may not be inserted as the sludge T moving in. Therefore, in order to prevent the sludge T from flowing into the insertion tube 130, a door 131 is further provided to automatically close the opening when the water gate 230 is separated from the insertion tube 130.

The door 131 is rotatably fixed around the pivot shaft 132 at the upper opening of the insertion tube 130, and inserts a separate seating groove 133 so as not to interfere with the movement of the water gate 230. When the door 131 is closed, the door 130 may be engaged with the insertion tube 130 to prevent the door 230 from being caught by the door 131.

On the other hand, the rotation shaft 132 is interlocked with the torsion spring (not shown) for supporting the rotation of the door 131, the door 131 when the external force is not applied to the door 131 from the water gate 230 ) Can always close the opened upper surface of the insertion tube 130 (see Fig. 5 (b)).

According to the present invention as described above, by accumulating the deposition position of the various sludge generated in the drainage pipe as possible as possible to increase the efficiency of the sludge removal operation, the sludge can be lifted up and removed at once, the sludge removal work time It is effective to shorten.
