Description

Detailed Description of the Invention The purpose of this invention is to collect a certain amount of rainwater, etc. by making only the upper part of the side wall of the rainwater gutter in the upper part of the diversion type gutter permeable, while the lower part is used as a sewage gutter. By making the entire side wall of the rainwater gutter permeable, surface water such as rainwater can penetrate into the ground as much as possible, helping to restore the groundwater level and prevent disasters such as floods. It is about preventing.

Traditionally, other side gutters were made of impermeable concrete, etc., and their purpose was only to collect and dissipate all the water, but in recent years, ground subsidence and vegetation depletion due to the decline in underground water levels, and urban sewers have been affected by torrential rains that occur in a short period of time. As a result, rainwater, etc. flows concentratedly into rivers through side gutters and culverts, making it easy for floods to cause damage such as inundation.

Perforated type semi-permeable rainwater gutter with diversion type gutter shown in Figures 1, 2, and 6 (
In 1), the lower layer is made of impermeable concrete side wall (6) with an inner cover (4) as a wastewater groove, and the upper layer is rainwater gutter 91Q with a water permeable hole (3) only in the upper part of the wall and the other side walls are left open. A water-permeable concrete side wall (6) was used. Therefore, if the water reaches the upper part of the rainwater ditch, the water can permeate into the ground through the water permeation hole (3), and if it does not reach the upper water permeation hole (3), the purpose is to collect the water and use it effectively. This is a semi-permeable rainwater drainage gutter.

In addition, the water-permeable concrete type semi-permeable rainwater gutter with diversion type gutter (2) shown in Figure 4 has a semi-permeable structure with a water-permeable concrete side wall (5) instead of the water-permeable hole (3) only at the upper part of the rainwater gutter side wall in the upper layer. This is a diversion type gutter with a rainwater gutter.

Furthermore, when installing the cable, the gutter joints (7) are filled with mortar, etc., and the inner lid joints (8) are also filled with mortar to connect the gutter. In the permeable concrete type rainwater gutter side gutter (9) shown in Figures 5, 6, and 7, the lower layer is used as a sewage groove on the impermeable concrete side wall (6), and the inner cover (4) is installed throughout the upper layer of the rainwater gutter side wall. By using a permeable concrete side wall (5), the structure allows the water flowing through the rainwater gutter to permeate into the ground. When installing, the gutter joint (7) serving as the joint of the gutter itself is filled with mortar, etc., and the inner lid joint (8) is filled with mortar to integrate it with the gutter.

The perforated type gutter with perforated rainwater gutter C1O shown in Fig. 8 has a permeable hole (3) instead of the permeable concrete side wall (5), and is used as a permeable concrete type gutter with diversion type rainwater gutter (9). This is a diversion type gutter with a permeable rainwater gutter, which is the same as the above.

When the present invention has the above-mentioned structure and is used, it is installed as a side gutter on the roadside or center of a roadway or sidewalk, and the lower layer is a sewage gutter structure and the upper layer is a rainwater gutter.

The lower level sewage ditch can be turned into an underdrain by installing an inner cover, and in the process of collecting and discharging surface water such as rainwater into the upper level rainwater ditch, a certain amount of water is collected for effective use. In this case, the initial rainwater, which is a fixed amount of water, is contaminated by air pollution, roofs, road surfaces, etc., so the initial inflow of rainwater is collected at a water treatment plant, purified, and then released into the river to prevent river water pollution. Become.

Furthermore, when the water level rises above a certain level, perforated type and water permeable concrete type semi-permeable rainwater ditches with the function of permeating into the ground become underground through semi-water holes only in the upper part of the side wall or through the permeable concrete side wall. infiltrate into. In addition, by providing infiltration functions to both walls of the rainwater gutter, it is possible to prevent flooding and inundation caused by an increase in the amount of water in pipes, gutters, and rivers caused by concentrated heavy rain, which is a weak point of urban sewerage systems that can occur in a short period of time. To minimize the obstruction, the entire side wall of the rainwater ditch should be made permeable to drain water into the ground.Recovering the groundwater level by reducing the amount of river inflow and preventing ground subsidence, reducing the amount of sewage treated at the water treatment plant, and water flow into the river. The purpose was to help prevent delays and vegetation depletion.

Claims (1)

[Claims] Semi-permeable rainwater gutter sidewalls, in which the lower part of the diversion type gutter is used as a wastewater ditch, and only the upper part of the sidewall of the rainwater gutter, which is the upper part, is made permeable; and fully permeable rainwater gutter sidewalls, in which the entire rainwater gutter sidewall is made permeable. These are a semi-permeable rainwater gutter and a permeable rainwater gutter.
