The present invention relates to a manhole including a main body that is variable according to the pipe to be connected, wherein the main body of the manhole is formed by assembling a plurality of unit body members and a pipe connection member, wherein the unit body members are planar, circular arcs. The unit body member is divided into a flat unit body member forming a curved unit body on a flat surface and a straight line. Each unit body member comprises a rectangular plate and a joint flange case protruding from the edge of the plate to form a tubular structure. The connection member, including a joint flange case of the tubular structure corresponding to the joint flange case of the unit body member, by connecting the pipe to be connected inside, as well as possible to assemble the body portion of the size and shape suitable for the construction site, after construction The present invention relates to a manhole comprising a main body that is variable according to a tube to be added, removed or changed.

In general, a manhole is a structure of a vertical pipe that allows a worker to enter and exit for maintenance or management in an intermediate section such as a water and sewage pipe, a communication line, and a transmission line buried underground. Body portion of the vertical pipe structure connected to the side; A base supported by the main body; It consists of a lid part comprised on a main body part.

This manhole installation method is installed by on-site casting method and assembling each component. On-site casting method installs the formwork at the place where the manhole is installed and reinforces the reinforcing bars, then places concrete in the formwork and undergoes a certain curing period. After removing the formwork, the manhole is manufactured and constructed.

The method of assembling each component is a method of manufacturing a manhole by dividing each component such as a base part, a main body part, and a lid part, and then assembling it on-site, which is more convenient than a method of assembling each conventional component. Methods for construction are being developed.

For example, in Korean Patent Registration No. 1318655, a plurality of standing blocks having the same curvature surface are disposed radially, and a standing reinforcing rib is formed inside the standing block, and one side of the standing block is formed with a fitting hole. The other side of the entrance block is formed with a fitting groove, the individual fitting blocks are connected to each other through the fitting fitting groove and the fitting fitting groove is arranged in a cylindrical shape, the pipe is penetrated between the standing block and the standing block 1 pipe insertion door is assembled, but the first through groove is formed in the center of the first pipe insertion door, the insertion door fitting hole is formed to be fitted into the insertion groove of the entrance block on one side of the first pipe insertion door, On the other side of the pipe insertion door is a 'block prefabricated valve chamber manhole', characterized in that an insertion door fitting groove is formed so as to be fitted into the entrance fitting hole of the entrance block. Posted.

However, the 'block-assembled valve chamber manhole' of Korean Patent Registration No. 1318655 completes the cylindrical manhole by assembling a plurality of standing blocks or masonry blocks having the same curvature surface, which is manufactured by the same curvature surface in advance. The size and shape of the manhole that can be formed is limited, and as a result, it is not possible to change the size and shape of the manhole according to the use, such as the place where the manhole should be constructed, the sewer pipe for water pipes, and the communication or transmission line. There was a problem that can be installed only in the valve chamber manhole.

This problem is also the same as the manhole method of assembling the respective components, such as the base portion, the main body portion, the lid portion and manufactured in advance, assembling each component in the field, so that the body portion of various sizes and shapes can be achieved There is a need for developing a manhole including a main body that is variable depending on the pipe to be connected.
