The present invention relates to an apparatus for manufacturing a manhole block, a method for assembling thereof, a method for manufacturing a manhole block, and a manhole block manufactured by the same, and more particularly, an apparatus for manufacturing a manhole block, which improves quality and productivity by improving a structure thereof, An assembly method, a method of manufacturing a manhole block, and a manhole block manufactured thereby.

In various civil works, building works, and road works, sewage pipes for treating rainwater, sewage, and wastewater are required. The manhole block is installed in the middle of the sewer pipe for the purpose of inspection, cleaning, ventilation, ventilation, bonding, branching, etc. in the conduit.

The manufacturing method of manhole generally used is largely divided into the method of cast-in-place and the method of using a ready-made manhole block.

Currently, the field casting method that is widely used is to install the formwork in the place where the actual manhole block is installed, and to assemble the reinforcing bar, and then the concrete produced by mixing the predetermined materials is poured into the formwork and after the predetermined curing period, This is a method of manufacturing the manhole block by removing the.

However, the above-described site casting method has many problems. First, the manufactured manhole block has a problem in that it is difficult to completely block leakage due to the inability of connecting the inlet and outlet pipes to be precisely constructed, and to install the formwork at the site, thereby making it difficult to adjust the height of the manhole block. In addition, there is a problem in that the construction period is prolonged due to the need for curing period of the poured concrete, resulting in traffic jams, thereby increasing civil complaints. In addition, construction costs are also relatively high.

As an alternative, a method of combining the on-site manhole block using the existing manhole block has been proposed as an alternative, and the national standard (KS F 4012: concrete manhole block for sewerage) was enacted and revised in 1970. Over and over to the present.

Referring to Figures 1 and 2, the configuration of a general ready-made manhole block is as follows.

As shown in FIG. 1, the ready-made manhole block 1 has a connection port 31 to which an inlet pipe and an outlet pipe can be connected, and a lower spherical manhole block 30 with a lower portion blocked, and an upper portion of the lower spherical manhole block. The upper manhole block 10 is coupled to the upper and lower portions of the vertical sphere manhole block 20, provided with an upper portion of the vertical sphere manhole block 20, having a check hole 11 is inserted into the manhole cover 10 It is configured to include. And the sealing member (41, 42) for blocking the leakage is fitted to the site where each manhole block is assembled.

The ready-made manhole block 1 has spigots 23 and 33, which are fitting parts of the manhole blocks, or sockets 15 and 25, which are parts corresponding to the spigots when the manhole blocks are mutually coupled. Formed. First, a spigot 33 is formed at an upper portion of the lower spherical manhole block, and a socket 15 is formed at a lower portion of the upper manhole block 10. In addition, the vertical sphere manhole block 20 has a spigot 23 at the top and a socket 25 at the bottom, respectively.

By the spigots 23 and 33 and the sockets 15 and 25, the respective manhole blocks can be smoothly coupled and can withstand the external force in the transverse direction.

Meanwhile, although not shown, an inclined sphere manhole block may be further provided between the vertical sphere manhole block 20 and the upper plate manhole block 10 so as to narrow the upper tube diameter and sufficiently endure the load on the road surface.

And the conveying bolt 52 which can convey the molded manhole block is fastened to the fastening nut 51 provided on the outer surface of the manhole block. 1 and 2 illustrate a form in which the transfer bolt 52 is fastened to the vertical sphere manhole block 20.

On the other hand, the lower spherical manhole block 30 is provided with a plurality of connection ports 31 for connecting the inlet pipe or outlet pipe.

In addition, an inverter 37 may be provided at an inner lower portion of the lower spherical manhole block 30, and the inverter 37 smoothly flows sewage in the manhole block and prevents deposition of dirt. It plays a role. The inverter 37 is mainly provided in the manhole block for the treatment of sewage.

The general manufacturing apparatus of the lower spherical manhole block of the ready-made manhole block comprises an outer mold having a bottom, and an inner mold installed at a position raised by the bottom thickness of the lower sphere in the outer mold. And a predetermined fixing device is installed so that the inner mold is positioned to be raised by a predetermined height in the outer mold.

The manufacturing method of the lower spherical manhole block through such a manufacturing apparatus will be described taking the case of using wet concrete as an example.

Here, the wet concrete refers to concrete in which the slump value, which is a value for measuring the degree of concrete dough, is concrete that is injected into the forming space.

First, the concrete produced by mixing a predetermined material in the molding space formed between the outer mold and the inner mold is introduced to the bottom thickness of the lower sphere manhole block, and the concrete is first cured, and then the outer wall of the lower sphere manhole block is formed. The concrete is put back into the space and cured again.

Here, curing refers to a process of curing the completed manhole block by a predetermined method, by the curing process to protect the concrete in a condition suitable for the hydration of cement for a certain period of time to harden the concrete.

After curing is completed, the inner mold and the outer mold are demolded, the fixed politics installed on the floor are removed, the fixing device is removed, and the remaining space is filled with concrete to complete the manufacture of the manhole block.

However, the above-described conventional manhole block manufacturing method and the manhole block has the following problems.

First, there is a problem in that the manufacturing cost of the upper plate manhole block, the vertical sphere manhole block, the lower sphere manhole block constituting the manhole block must be provided separately.

Secondly, the bottom surface and the wall of the lower spherical manhole block could not be manufactured at one time, resulting in a long manufacturing time. And when the bottom of the concrete manhole block and the wall at the same time to produce the concrete at the same time there was a problem that the inner mold is rising due to the buoyancy of the concrete is not yet hardened.

Third, since the height of the outer mold or the inner mold should be changed according to the height of the lower spherical manhole block to be manufactured, there is a problem that the manufacturing cost of the mold increases because a full set of molds must be separately prepared according to the standard.

Fourth, there was a problem that it is impossible to form an inverter that must be installed in the manhole block for the treatment of sewage in order to facilitate the flow of sewage and to prevent the deposition of sewage. Therefore, there was a hassle to install a separate inverter at the construction site.

Fifth, it was not easy to form a fastening nut, a connection port, etc. for fastening a spigot or a transport bolt, which must be essentially configured in the manhole block, with a conventional manhole block manufacturing apparatus.

Sixth, when using the method of inserting the connecting member in the manhole block to be coupled to the manhole blocks, the upper part of the lower spherical manhole block should be formed with a connecting member fastening hole for fastening with the connecting member, but it was not easy to install Even if it is possible to install even precise placement was difficult.
