Description

Polygon manhole for multiple compound structures

The present invention relates to a method for manufacturing a polygonal manhole for a multi-composite structure, and a device thereof, and more particularly, to an inner diameter part made of a synthetic resin, a core layer of a resin and silica sand to reduce weight, and a coating layer using a resin and glass fiber. Light weight and strong body makes it easy to install and semi-permanent in life. The bottom body and upper body are made of resin concrete, so it is water tight and semi-permanent. The present invention relates to a method for manufacturing a polygonal manhole for a multi-complex structure, and an apparatus thereof.

In general, the manhole is a hole that allows people to enter and exit the road, and the place where it is installed is installed at the place where the thickness or direction of the pipe changes, the starting point, the intersection point, the middle of the straight line between the length, and the air. It is generally installed at intervals of about 50 meters.

The shape is the most convenient circle for construction, in addition to the square, oval, etc. The entrance is surrounded by a frame or stone made of iron around it and covered with a round lid, usually cast iron or reinforced concrete, about 60 cm in diameter.

The main body is made of concrete or brick, and the inside diameter of the passage hole is often 1 to 1.2m, and the floor is made to be equal to or slightly lowered to the bottom of the pipeline to accommodate the sediment. The depth depends on the depth of the pipeline, but the depth is over 100m.

The manhole is embedded in the ground and used, connecting pipes are integrally formed on both lower sides of the manhole body, flanges are formed on the upper and lower parts of the body, and a lid is installed at the center of the body.

These manholes are mainly made of concrete, and they are constructed by using concrete ready-made concrete that is cast in the field or made into a certain form.

In case of placing concrete on site, it is necessary to install some form of formwork, insert reinforcing bars into the installed formwork, and then add concrete. Therefore, construction is not easy and construction is delayed, which is the main cause of traffic congestion.

In addition, when using concrete ready-made products made in a certain form, the factory manufactures them to specifications and transports them to the site, which causes inconvenience in the removal process that requires the mobilization of large heavy equipment, and the expense of additional equipment. .

In addition, when the concrete is manufactured and installed, its own elasticity is insufficient, and durability due to vibration of the ground is not sufficient, and watertightness is not good.

When attaching the branch pipe, since the opening is formed in the inner and outer molds, it is impossible to work precisely according to the outer diameter of the tube, and the strength of the connection after the connection may be weakened. If the ground load acts differently, the bending stress is applied to the joints, so that the cracks can easily occur at the joints.
