Description

Crosswalk environment improvement rain gutter and its construction method {STREET INLET FOR IMPROVING ENVIRONMENT OF CROSSWALK AND CONSTRUCTING METHOD THEREOF}

The present invention relates to a rain gutter for improving the environment of a crosswalk and a construction method thereof, and in detail, a perforated pipe is installed in the space of the side opening in contact with the crosswalk, and after filling the aggregate in the perforated pipe, natural gravel grating capable of permeating the upper surface of the aggregate is provided. A crosswalk environment that prevents the crosswalk from getting caught in the crosswalk by installing it, and induces rainwater that has penetrated through the merit pipe through rain gutters located at both ends of the crosswalk to provide a comfortable crosswalk passage for pedestrians at the crosswalk. It relates to an improved rain gutter and its construction method.

Rainwater flowing on the road surface of the road flows into the side opening installed at the edge of the road, is blocked through a rain gutter, and then quickly discharged to the sewer pipe to ensure the safety of road traffic and prevent flooding of adjacent areas.

As shown in FIG. 1, such a rain gutter includes a main body 10 made in a hexahedral shape as a whole; A grating 20 covered on the upper part of the main body 10; It is a structure in which the side surface of the main body 10 is opened and the connection pipe 30 is connected.

In particular, it is a structure in which the height of the bottom of the main body 10 is lower than the height of the bottom of the connection pipe 30.

In the conventional rain gutter (S) configured as described above, when rainwater from the road is introduced through the grating (20), rainwater flows in together with the soil that has previously been deposited on the road around the grating (20). Likewise, the soil and rainwater flowing in through the grating 20 are naturally deposited on the bottom of the main body 10, and the rainwater flowing in together with the soil is drained into the sewer through the connection pipe 30. Processed.

Typically, rainwater or surface water from a road is discharged from a rain gutter to a sewage pipe through a connection pipe.

Looking at the discharge process, the rainwater from the rain gutter is located lower from the ground than the rain gutter so that rainwater from the rain gutter can easily flow down into the sewer pipe. Accordingly, the connection pipe connecting the outlet of the rain gutter and the sewer pipe is connected obliquely.

However, in the related art, the work of connecting the outlet of the rain gutter and the end of the connecting pipe has been very difficult and difficult.

In order to solve this problem, a rain gutter having an angle-adjustable bellows, which is Korean Patent No. 10-1902536, is disclosed.

The rain gutter having the angle-adjustable bellows, as shown in FIG. 2, the rain gutter main body 100 is configured such that the bellows coupling portion 120 is embedded in the inner portion of the rainwater outlet 113.

The bellows coupling part 120 may be made of a synthetic resin material such as plastic. The bellows coupling part 120 may be manufactured in a form integrally coupled to the rain gutter body 100, and as an example, the rain gutter body 100 of the invention is in a state in which the bellows coupling part 120 is inserted into the formwork. By pouring concrete into a form and curing it, the bellows coupling part 120 may be integrally configured with the rain gutter main body 100.

However, when the rain gutter with the angle-adjustable bellows is installed at the side of the crosswalk, the boundary stone is constructed at the same height as the side of the side for the convenience of passage of the handicapped, and the side of the side is a small reservoir to prevent water from splashing on the passerby. In order to do so, it must be precisely constructed, but when an error of 5 mm occurs in concrete construction of the length of the long crosswalk and the width of the sideways, the 5mm depth is highly precise enough to cause water splash damage to pedestrians at the crosswalk. It should be done, but it is a reality that does not reach ultra-precise construction and causes inconvenience to pedestrians on the crosswalk when it is obese.

Domestic registered patent No. 10-1902536

The present invention is to solve the above problems, by installing a perforated pipe in the space of the side opening in contact with the crosswalk, filling the aggregate in the perforated pipe, and then installing a permeable natural gravel grating on the upper surface of the aggregate to prevent biting of the crosswalk. Also, rain gutters located at both ends of the crosswalk guide rainwater that has penetrated through the merit pipe to facilitate drainage, and provide a crosswalk environment improvement rain gutter and its construction method to provide comfortable crosswalk passage to pedestrians at the crosswalk. It has its purpose.

In addition, the present invention is a rain gutter made of precast in a state in which a synthetic resin elbow pipe is connected to a sewage pipe exposed by excavation and an ultra-fast diameter mortar is placed inside the excavation space in which the elbow pipe is installed to fix the lower part of the elbow pipe.
