Description

ASSEMBLY MANHOLE}

The present invention relates to a prefabricated manhole, and more particularly, to a prefabricated manhole structure in which a manhole body of a metal material, a sealing plate, and a mesh member are coupled to each other to be assembled at a construction site to facilitate manufacture and transportation, The present invention relates to a prefabricated manhole for facilitating the installation, repair, and replacement of a prefabricated manhole structure or a connection pipe by allowing a connecting pipe to be easily installed at an inlet and an outlet of a manhole.

Sewage pipe construction for the treatment of stormwater and wastewater is essential for the construction of various engineering works such as civil engineering, construction work, and road construction. In the middle of the sewer pipe, the manhole is constantly used for inspection, cleaning, ventilation, ventilation, Install at intervals.

The most commonly used manhole construction method is a manhole which is put into place as the Korean Patent No. 1171870. However, it has a disadvantage of a manhole placed in the field, such as a prolonged construction period, an increase in construction cost, The quality of the product, difficulty in securing skilled workers, increase in complaints, difficulty in completely blocking the leakage, difficulty in adjusting the height, and the like.

As an alternative to this, a national standard (concrete manhole block for sewerage KS F 4012) was established in 1992 to encourage the use of precast concrete manholes, which are now common in developed countries,

The use of the prefabricated manhole block improves the convenience of the construction due to shortening of the air and standardization of the product. However, it is difficult to supply the completed one manhole due to the diversity of manhole installation height in the field and the conveyability of factory products, It is inevitable to supply products that are divided into pieces.

Therefore, in the construction site, a manhole block is constructed by stacking and assembling a plurality of manhole blocks inevitably. As a result, there is a part that is vulnerable to inflow of groundwater and leakage of sewage between the block and the block.

In order to solve the above-mentioned problems, the present invention, which has been devised to solve all of the above problems, is to provide a manhole in which a prefabricated manhole is directly assembled in accordance with an installation environment at a site construction site, and a divided prefabricated manhole structure is formed of a corrosion- A prefabricated manhole which is easy to carry and can be firmly assembled / connected to any form of a connection pipe (or a drain pipe) connecting the inlet port and the drain port formed in the side of the manhole, thereby providing a portable manhole having excellent transportability, ease of assembly, and durability .

The present invention relates to a cylindrical or tetragonal body having first and second assemblies each having a connecting hole formed on one side thereof, a coupling piece bent inward at one end, an upper end and a lower end of the coupling piece and having mutually symmetrical structures, A plurality of reinforcing bars connected to mutually opposite sides across an upper space of the main body, a mesh member covering the upper surface of the assembled main body and having a plurality of through holes formed on the entire surface thereof, And a supporting frame which is fastened to the outer periphery of the connecting hole formed on one surface of the first and second assembling parts of the main body.

In addition, the present invention provides a prefabricated manhole in which the connecting ports formed on one surface of the first and second assemblies of the main body are formed in a circular or square shape.

According to the present invention, it is possible to adjust the manhole size or the shape of the divided prefabricated manhole, which is manufactured so as to be assembled with the corrosion-resistant metal material, according to the installation environment in the field so that the prefabricated manhole is easily manufactured, Since no separate transport equipment is required for installation at the quarry, it is easy to construct, the construction cost is reduced, various types of pipes can be used regardless of the material or shape of the connection pipe (or drain pipe) It has an advantage of being durable because it has an airtight structure.
