The present invention relates to a dividing manhole which is buried in a certain section on the road, and in particular, the manhole can be smoothly assembled even after the main pipe and the dividing valve are installed first, thereby shortening the air and increasing workability. Note relates to prefabricated dividing manholes.

In general, a water separator valve is installed on the road every certain section, and it is used to cut the area of the water separator valve section by water pipe work. At this time, it can be easily operated if necessary to protect the water separator valve. The dividing manhole was constructed.

That is, when attempting to install the water-draining manhole (1) before, as shown in FIG. 3, the excavation so that the underground space is formed on the installation of the water-draining valve 20, and then cast concrete on the bottom surface ( 30), a brick (1) for supporting the water supply main pipe (11) is stacked in a cylindrical shape on the base portion 30, the formwork is installed on the brick (1) after the installation of the main pipe (21) After the concrete is poured to form a cylindrical support wall (2), after the formation of the support wall, the formwork is dismantled again, after the formation of the support wall (2) lid support of the metal material for the installation of the manhole cover 70 Settle the socket 60, install the formwork in the circumferential direction for fixing the lid support socket 60, and then cast concrete to form a fixed portion 80, after the formation of the fixed portion 80 of the manhole cover ( Watering by laying asphalt or concrete on the road to match the height of 70) Will who completed the hole 10.

As described above, air is delayed more than necessary due to the number of times of assembling formwork and dismantling concrete and constructing bricks for the construction of the distillation manhole 10. In addition, there were some defects such as cause of traffic congestion due to inconvenience of vehicle traffic due to delay in construction.

On the other hand, in Japanese Unexamined Utility Model Publication No. H3-18254, the prefabricated manhole has been previously filed by prefabricating the preliminary prefabricated manhole by simply manufacturing the foundation part, the support pipe, and other structural parts in advance.

As such, the conventional prefabricated water-draining manhole can be completed by simply assembling prefabricated structures in the field, but it is possible to significantly reduce air and air expenses since it is unnecessary for a professional technician, but the assembly order may be limited. There was no choice but to.

In other words, the assembly procedure of the conventional prefabricated distillation manhole is to insert the pipe support pieces (5) in the main pipe (1), and then install the distillation valve (2) in the main pipe and the base portion on the bottom bottom (4) is installed, and the pipe support pieces (5) are assembled so that the pipe support pieces (5) are fitted into the cutout grooves (6a) formed by symmetrically opening the lower end of the pipe support pieces (5) on the upper portion of the foundation. The tube 6 is assembled on the base 4 and the other superstructures are sequentially stacked on the support tube 6.

In this case, the pipe support pieces 5 must be inserted into the main pipe 1, and the reason why the dividing valve 2 is installed in the main pipe is that the structure of the pipe support pieces 5 is a doughnut-like structure. This is because 5a) is made of one pipe support piece 5 formed integrally.

As described above, the conventional prefabricated dividing manhole is actually completed by simply assembling the prefabricated structures in the field, so that the air is greatly shortened. However, the prefabricated manhole is inserted into the lower cutout groove 6a of the support tube 6. Since the pipe support piece 5 is made of a single cylinder which is formed integrally with the pipe through hole 5a formed in the center like a donut type, the pipe support piece 5 must be connected to the main pipe 1 after its main pipe is connected. Laminated assembly in the state of being fitted to the pipe (1). Therefore, there is a problem that workability is lowered because there is no flexibility in the assembly order.

In addition, the prior art is necessarily the upper part of the base part 4 because the pipe support piece 5, the base portion 4 and the support tube 6 are assembled in contact with each other and the fitting structure is fitted into the protrusions and grooves, respectively. In the pipe support piece 5, the support pipe 6 is laminated and assembled on the pipe support piece. In other words, after the support pipe 6 is installed on the base 4, the pipe support piece 5 cannot be assembled by pushing the pipe support piece 5 sideways into the cutout groove 6a.

Thus, the conventional assembly that can only be assembled by lamination is limited to the assembly order, the workability is not only degraded, there is a hassle to completely remove the entire manhole during the maintenance work, such as replacing the pipe support (5). .

It is an object of the present invention to provide a prefabricated distillation manhole that can increase the overall workability by allowing the manhole assembly work even after the pipe piping and the distillation valve are completely installed.
