Description

A water blocking device for a square sewage block, a water diverter for a square sewage block, and a floor repair method for a square sewage block using the same {WATER SHELTER APPARATUS AND WATER DIVERTING APPARATUS AND PIPE REPAIRING METHOD FOR USING THEREOF}

The present invention relates to a water blocking device for a square sewage block, a water return device for a square sewage block, and a floor repair method using the same, and more particularly, to a rectangular sewage block comprising a soft tube wound in a roll shape, a hanger and a supporting member Install the water circulating device in the longitudinal direction of the square sewage system, and with the sewage diaphragm installed at both ends of the section to be repaired, pass both ends of the tube of the square sewage diaphragm device through each closure device. It relates to a water block device for a square sewage block, a water circulating device for a square sewage block, and a floor repair method for a square sewage block using the same.

In general, a siege is a structure for moving drinking water, living water, rainwater, or domestic sewage.

Such a girder is mainly made of concrete, and the cross section is often round, rectangular or oval. In particular, in case of leaks due to deterioration over time, cracks due to impact, or expansion and contraction of the fastening part, the molded girder buried underground is newly built by excavating the dungeon buried area, or the leaking part inside is directly repaired.

However, in the former method, there are problems such as ground subsidence due to excavation work as well as increased construction period and cost. To solve this problem, the method is used to repair the ground in a dry state without excavating the ground or dismantling the damaged mold. This is because the large-scale traps for sending a large amount of sewage discharged from densely populated areas to the sewage treatment plant, for example, the sewage traps around the Han River built in the 1980s, have a cross section of about 2.8×2.8m in width and length. It is not only very dangerous for humans to perform repair work after a certain section is maintained in a dry state by simply using only a water barrier, but even if it is assumed that the water barrier can sufficiently withstand the water pressure caused by a large amount of sewage inflow, the water barrier is installed. As severe stress concentration occurs in the molded girder, damage to the girder is expected due to the girdle itself. As a pretreatment step for the maintenance of such a large girder, a method for blocking the girder which secures stability was developed.

Among them, the water circulating method that diverts the water and sewage upstream of the target to be repaired to the ground or another path from the interceptor or manhole is widely applied. As a water turning device used in such a water turning method, there are those disclosed in Patent Document 1 below and known.

A general conventional water circulating construction method is to pump up sewage from the upstream manhole where the packer is installed to the ground, and then transfer the pumped sewage to the downstream manhole where the packer is installed. However, in the case of such a conventional water rotation construction method, a large amount of power is required to pump up sewage, a water pump that is inconvenient to move is required, and the installation and dismantling operations are simple because the water rotation hose must be installed via the ground. Therefore, there is a problem that it is difficult to construct quickly.

In addition, there is a limit to the amount of sewage that can be pumped up by a pumping machine, so it was not possible to carry out the pumping itself in medium and large sized silos with high flow. Korean Patent Application Laid-Open No. 10-2005-0101069 discloses a water rotation construction method for improving the conventional water rotation construction method.

However, in this method of draining water, a means for draining water is installed to allow sewage flowing into the mold to flow through the ground. However, this also has a problem in that it requires a number of equipment and installation places for water rotation because it is carried out on the ground.

On the other hand, a conventional non-excavation repair method is disclosed in Korean Patent Application Laid-Open No. 10-2013-0059083 (pipeline non-excavation total repair method).

In the case of this non-excavation repair method, water is drained to the outside to prevent sewage from flowing inside the mould, then the lining material is towed into the mould, and then air is injected into the lining material by air pressure. The lining material was expanded and adhered to the inner wall of the mold, and the mold was repaired by curing the lining material using air.

However, in the case of using this method, several large devices such as a heavy machine device, a blower, and a hot fan are required to inject air, and the noise generated by the above devices is a problem, and the location where the mold to be repaired is buried is on the side of the road. In this case, there is a problem of traffic congestion due to several devices installed on the ground. In addition, even if a hot air fan is used to cure the lining material introduced into the interior faster, curing by steam takes a lot of time, so it is usually only possible to work late at night or early in the morning when there is little traffic, so there is a limit to the time that an operator can work. have. In addition, in the case of the conventional non-excavation repair method, there is a limit in that repair of medium and large moulds cannot be carried out because repair is possible after performing water return to the outside.

In addition, when a sudden rise in the water level inside the cage occurs due to heavy rain or guerrilla heavy rain, there is a problem in that the safety of the workers cannot be guaranteed and a safety accident occurs.
