DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

1 and 2 and 3, the sump 10 according to the present invention is installed included in the side opening (2) installed on one side of the road (1). That is, the sump 10 may be installed at regular intervals in the longitudinal direction of the side opening (2). Therefore, the water collecting well 10 serves to collect the rainwater flowing into the rainwater drainage channel 4 of the side drain drain block 3 and discharge it to the sewer pipe 6.

The sump well 10 includes a sump body 100, a rainwater backflow damper 110, and a sump cover 120 as shown in FIGS. 3 to 5.

Sump body 100 may be made of concrete. The water collecting well body 100 penetrates through the water collecting chamber 102 having an opening 102a upward and connected to the water collecting chamber 102 on both side walls of the water collecting chamber 102 so that a predetermined amount of water can be collected at a predetermined depth. The sump well inlet 104 which allows the inflow of rainwater from the drainage path 4, and the sump well outlet 106 for connecting with the sewer pipe 6 in the front wall.

At this time, the water collecting well inlet 104 is located at a predetermined height at the bottom of the water collecting chamber 102. That is, the sump well inlet 104 is formed above the sump well outlet 106. Therefore, the rainwater introduced into the collection chamber 102 through the collection well inlet 104 may be discharged to the collection well outlet 106 by a drop.

Rainwater backflow prevention damper 110 can be made of metal, synthetic resin, rubber. Rainwater backflow prevention damper 110 allows rainwater inflow from the sump well inlet 104 to the sump chamber 102 and blocks the reverse flow from the sump chamber 102 to the sump well inlet 104. Rainwater backflow prevention damper 110 is located in the collection chamber 102 is installed close to the collection well inlet 104. At this time, the rainwater backflow prevention damper 110 is installed as a hinge to the sump body 100 is capable of rotating opening and closing. Rainwater backflow prevention damper 110 is the hinge bracket 112 installed on the opening 102a side, the opening and closing plate 116, the opening and closing plate that one end is connected and rotated to the hinge shaft 114 built in the hinge bracket 112, It consists of the watertight packing 118 provided in the inner surface of 116. As shown in FIG.

At this time, the watertight packing 118 is made of rubber or a cone, and its diameter is larger than the diameter of the sump inlet 104. Therefore, when the rainwater backflow prevention damper 110 is closed, the watertight packing 118 is completely in contact with the end face of the sump well inlet 104.

On the other hand, since the fixed end of the opening and closing plate 116 is bent and connected to the hinge shaft 114, the center of gravity of the opening and closing plate 116 is at an eccentric position away from the hinge shaft 114 by a predetermined distance. Therefore, the opening and closing plate 116 is moved in a direction that is always closed by the center of gravity acts in the eccentric position is subjected to a force placed in a direction perpendicular to the direction of the sump inlet 104.

The opening and closing of the collection well cover 120 is installed at the opening 102a side of the collection well body 100. The sump cover 120 has an area corresponding to the opening 102a. Sump cover 120 may be made of a strong metal, concrete and the like. It is clamped to the sump body 100 through the sump cover fixing clamp 140. At this time, the sump cover 120 and the sump cover fixing clamp 140 is inserted into the sump cover 120 is connected to each other through a bolt connected to the sump cover fixing clamp 140.

At this time, the clamp mounting groove 102b is formed in the opening 102a for the installation of the sump cover fixing clamp 140. The clamp mounting groove 102b has an approximately L-shaped passage structure on the side of the opening 102a facing each other. Therefore, both ends of the sump cover fixing clamp 140 are inserted in the vertical direction in the clamp mounting groove 102b, and then fixed in the horizontal direction.

On the other hand, as a means for adjusting the horizontal posture of the sump body 100, the horizontal adjustment connecting plate 130 fastened with bolts on both sides of the front and rear of the sump body 100, as shown in Figure 1, the horizontal Horizontal adjustment bolt 132 that is screwed vertically to the adjustment connection fixing plate 130 may be further configured.

In the present embodiment, the sump fixing body 100 is provided with four horizontal fixing connecting plate 130 and the horizontal adjusting bolt 132, respectively. Therefore, it is possible to correct the horizontal position of the sump body 100 by adjusting the height position of these horizontal adjustment bolt 132 during construction.

In addition, a silicone foam O-ring 150 is further installed on the outer side wall of the sump body 100 in a cross section of the sump inlet 104 to remove a connection gap with a neighboring side drain block 3. Can be.

The operation of this embodiment configured as described above will be described.

First, when there is no inflow of rainwater on the road 1, there is no rainwater pool in the water collecting chamber 102 of the side mouth 2 side water collecting well 10. Accordingly, the opening and closing plate 116 of the rainwater backflow prevention damper 110 is positioned substantially vertically by the rotational force according to its own weight to close the sump well inlet 104 as shown in FIG. 3A.

Therefore, even if odor leaks from the sewage pipe 6, it is shielded by the sump cover 120 and the rainwater backflow prevention damper 110 to prevent external odor.

On the other hand, when rain-induced road-side rainwater flows into the side opening 2 along the direction of the arrow K, rainwater is collected into the water collecting well 10 through the rainwater drainage channel 4 inclined toward the water collecting well 10. .

At this time, the rainwater flowing into the water collecting well inlet 104 rotates upwardly to open and close the opening and closing plate 116 of the damper 110 for preventing rainwater backflow at a flow rate. When the opening and closing plate 116 is opened in this way, rainwater flows into the collection chamber 102 and is smoothly discharged to the collection well discharge port 106.

On the other hand, when rainwater flows back through the sewage pipe 6, the water pressure in the collection chamber 102 is increased. When the rising water pressure is greater than the opening force of the opening and closing plate 116 of the rainwater backflow prevention damper 110, the opening and closing plate 116 is pushed in the opposite direction to block the sump well inlet 104 (see FIG. 3A).

Therefore, when the rainwater flows back, the sump well 10 itself does not allow backflow, thereby preventing flooding of the road adjacent to the side opening 2. In addition, the opening and closing plate 116 of the rainwater backflow prevention damper 110 is automatically opened as the amount flowing into the sump well inlet 104 is increased, thereby improving drainage efficiency.

On the other hand, as shown in Figure 6 the upper surface of the sump body 100, the boundary stone mounting jaw 107 that can be mounted to the sidewalk road boundary stone 8 is formed, is located close to the boundary stone mounting jaw 107 is the sump body 100 The boundary stone fixing bolt 160 fastened to the) and the boundary stone fixing plate 162 inserted into the boundary stone fixing bolt 160 to press and fix the boundary stone may be further configured. Therefore, the sidewalk road boundary stone installed in the neighboring side drain drain block 3 may be continuously installed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
