Description

Rainwater and Sewage Separation Wall Structure of Sewer for Rainwater and Sewage

The present invention relates to the sewage pipe drainage and sewage dividing wall structure, and more particularly, to the sewage pipe drainage and sewage dividing wall structure in which the installation is completed in a short time and the watertight structure by the vertical index member is formed quickly and precisely.

In general, sewer pipes (sewers) are installed in the basement of the city to guide the movement of sewage, sewage, and rainwater to sewage treatment plants, rivers, and rivers.

By the way, living sewage and sewage must be sent to the sewage treatment plant for the purification process, but in the case of rainwater (rainwater) does not need to be sent to the sewage treatment plant. If rainwater is sent to the sewage treatment plant along with sewage, there is a problem that the purification process takes a lot of cost and time, it is preferable to guide the rainwater to flow directly into the river or river.

As described above, various sewage blocking blocks for guiding the sewage and rainwater to move in a separated state have been proposed. For example, there has been proposed a structure for separating various sewage and rainwater from Registration Utility Model Publication Nos. 20-0184310, 20-0255673, 20-0261914, 20-0284854 and 20-0284855. .

In the conventional structure for separating sewage and rainwater, a barrier wall is formed by installing a plurality of blocks in series, and each block is formed by forming a protrusion and a groove to be fitted in a fitting manner. It consists of a configuration for installing the expansion index plate. The packing or the water-expandable index plate is made of a water-expandable elastic rubber material that absorbs moisture and expands in volume.

However, it may take up to 10 days or more for the packing or the water-expansion index plate to fully expand and seal the gap, and the expansion time may vary depending on the installation time (summer or winter) or water temperature. It is very difficult to predict when to complete.

Furthermore, if time elapses after the installation of the sewage separation block, the packing or the water expansion index plate may expand and protrude to the upper surface. That is, the water expansion index plate is pushed upwards from the bottom to be exposed to the outside, so as to protrude. There is not enough space to fill in the gaps. This causes a problem of the appearance, it is not possible to achieve a sufficient sealing of the inside, there is a problem of mixing sewage and rainwater.

Accordingly, an object of the present invention is to solve the above problems, to form a pressing projection on the end surface of the coupling protrusion and to install an expansion suppression member on the top of the coupling groove to prevent the vertical index member is expanded to the outside. Therefore, to provide excellent sewage pipe and sewage dividing wall structure which is excellent in sealing effect and able to complete installation work quickly.

The sewage pipe drain and sewage separation wall structure proposed by the present invention is configured to have a trapezoidal cross-section, and a coupling groove is formed in each of the longitudinal sides in the height direction and inserted into the coupling groove located adjacent to the opposite side. A plurality of main bodies each of which has a protrusion extending in the height direction, a vertical index member made of a water-expandable material inserted between a coupling groove and a coupling protrusion positioned adjacent to each other among the plurality of main bodies, and a protrusion protruding from the center of the coupling protrusion of the main body; And a pressing protrusion formed in the height direction of the main body, and formed in a "b" shape consisting of a vertical portion and a horizontal portion, and a vertical portion is fixed to an upper end of a coupling groove of the main body, and an upper end portion of the vertical index member on a bottom of a horizontal portion. It comprises a contact with the expansion preventing member. The expansion suppression member is formed of a vertical portion and a horizontal portion, in addition to the separate installation, the expansion suppression portion formed of a horizontal portion having a shape in which the upper end of the main body extends horizontally to block the upper end of the coupling groove is also applicable to the present invention.

The vertical index member is formed using a material such as water-expandable elastic rubber having a characteristic that the volume expands upon absorption of moisture.

The expansion inhibiting member may be fixed to the main body by using a small screw or bolt, or the main body may be extended to be integrally formed with the main body.

The pressing protrusion is formed to have a cross section of various shapes, such as triangular, semi-circular, semi-elliptic, trapezoidal.

According to the rainwater and sewage separation wall structure of the sewage pipe according to the present invention, it is possible to compress the vertical index member inserted between the coupling groove from the beginning so that the compression projection is formed again on the coupling projection of the main body, Even with the initial small water expansion, it is possible for the vertical index member to completely seal the gap between the engaging projection and the engaging groove. Therefore, it is possible to effectively complete the work of installing the structure of the separating wall (blocking wall) capable of sufficiently achieving the purpose for separating rainwater and sewage in a short time.

And according to the sewage pipe drain and sewage separation wall structure according to the present invention, the vertical index member inserted between the engaging projection and the coupling groove is prevented from expanding any more upward expansion member at the top, the vertical index member is to the side Expansion is done downwards and downwards, effectively sealing the gap as a whole.

Next, with reference to the drawings will be described in detail a preferred embodiment of the excellent and sewage separation wall structure of the sewage pipe according to the present invention.

When the compression protrusion 20 is pressed while pressing the vertical index member 30, and closes the gap between the coupling projection 14 and the coupling groove 12 by a slight water expansion, the sealing is made perfect Effect is obtained. That is, since the vertical index member 30 does not have to wait 10 days or more until sufficient expansion occurs, it is possible to complete the installation work of the separating wall (blocking wall) within a short time regardless of summer, winter, or water temperature. Do.

As shown in FIGS. 1 and 5, the expansion suppression member 40 is fixedly installed at the upper end of the coupling groove 12 of the main body 10.
