Description

Waterway cover manufacturing equipment and manufactured waterways cover

The present invention relates to the manufacture of a waterway cover. More specifically, the cover in contact with the waterway is precisely manufactured using a formwork, and sling rings are combined and dismantled to ensure smooth movement during installation and disassembly to eliminate inconvenience in passage. It relates to waterway cover manufacturing equipment and manufactured waterway covers that can be improved and applied to the concrete waterway and cover manufacturing industry, waterway installation industry, and waterway management and maintenance management industry.

Generally, a road is divided into a roadway and a sidewalk, and the roadway is paved with a road pavement made of impermeable asphalt concrete or cement concrete, and both edge areas of the road pavement are provided with primary drainage to drain water accumulated in the road pavement. As a facility, a road border gutter with a concrete structure is provided.

This type of ditch is a ditch made at the end of the road or at the border between the sidewalk and the roadway to drain the road surface. Depending on the cross-sectional shape, there are L-shaped and U-shaped ditches, and the water collected in the ditch is drained into catch basins made at appropriate intervals. It flows through the sewer pipe, and what is on the border of the street sidewalk and roadway is said to go.

Meanwhile, most of the conventional road border ditches are installed using a method of pouring them directly on site during construction. In this process, the slope of the side ditch is adjusted to allow water accumulated in the road pavement to easily flow into the side ditch. .

However, such conventional road border ditches require detailed construction by the contractor when adjusting the slope, but due to poor slope due to difficulty in slope adjustment, poor drainage such as water piling up on the road pavement during the rainy season It causes inconvenience to passing vehicles and pedestrians, and also impairs the aesthetics of the city due to concrete corrosion and damage.

In addition, conventional road border ditches require a long curing time to obtain the strength of concrete after being constructed using the on-site casting method, and management is required accordingly, but curing is difficult due to vehicle and pedestrian traffic in the city center. There is a problem that a lot of money is spent on maintenance and repair of the gutter due to damage and settlement of the gutter, material separation phenomenon, and decrease in strength.

To solve this problem, instead of installing a gutter using a casting method on site, a method is being implemented in which steel grating is manufactured in advance at a factory in a certain size and shape, transported to the site, and then installed.

At this time, the steel grating used is widely used as a cover for a collection drain to treat sewage or rainwater, and its shape is very diverse, ranging from concrete grating with a permeable groove formed on the top to the recent steel grating with a lattice structure or wave structure. It is developing.

However, steel grating is installed on the top of these concrete gutters to prevent various dirt from entering and allows rainwater to flow in, or a through hole is formed to allow rainwater to drain. These conventional factory-formed gutters are made of steel grating. Due to the installation of and the formation of through-holes, there is a problem that safety accidents occur, such as injuries caused by the heels of pedestrians' shoes falling into the steel grating or through-holes when using taxis or public transportation.

In addition, when vehicles with small wheels, such as strollers or inline skates, pass over the top of the grid-structured steel grating, the wheels get caught between the grids, or the vehicle passes on an uneven floor, causing the grating to shake violently. There was this.

Most of the concrete waterways made of conventional concrete gutters are open at the top, so there is a problem that vehicles such as cars, personal vehicles such as bicycles, and pedestrians fall.

In addition, conventional concrete water channels with concrete gutters have been constructed in the form of metal mesh nets or structures with closed concrete covers due to safety issues. However, in the case of metal mesh nets, there is a problem of damage caused by heavy transportation means, so in recent years, A concrete cover was adopted and connected to the gutter. However, the gutter and the concrete cover were manufactured using molds, so there was a problem in that the lower surface of the cover in contact with the gutter did not have precision, causing a gap and movement.

In addition, the concrete cover coupled to the concrete waterway made of a conventional concrete gutter was manufactured as a heavy material, and the hook for transportation protruded, causing inconvenience in passage such as getting caught and safety problems.

As a result, the precision of the cover made of concrete that covers the open upper part of the waterway made of concrete is improved to prevent separation, and a ring-shaped structure that can be fastened and disassembled when necessary for movement is made of concrete. There is an urgent need for an improved manufacturing device for manufacturing by landfilling during curing and a cover manufactured thereby.
