This invention relates to a method and device for repairing a part to prevent underground water, rainwater, etc.

入して硬化させる方法が知られている。 In sewage pipes, groundwater may infiltrate through joints or damaged parts, increasing the amount of water inside the sewage pipes. To this end, we regularly inspect the sewer pipes for leaks and water intrusion, find the leaks, and repair them. The inspection and repair method is to run a TV camera inside the sewer pipe, find the damaged area on a monitor on the ground, move a patch car to that location, and use the patch car to inject liquid filler into the damaged area and harden it. There are known ways to do this.

合においても起きた。 In this method, the amount of filler to be sent to the sewage pipe is calculated based on experience, and it is sent to the sewage car under pressure. However, if this pressure is not appropriate, the pressure will exceed the pressure that causes the sewage pipe to break, causing it to break. In addition, if the gap created at the damaged part or joint is small, the filler may not penetrate into the gap when the filler is pumped. This lack of infiltration is thought to be due to the presence of slightly compressed air in the space created on the back side of the sewer pipe.
As a result, the filler did not fit properly into this space, and the filler only covered the surface between the spaces, causing water to leak again even after repairs were made. This also happened when a filler injector was used to repair cracks in reinforced concrete walls.

る。 The present invention solves the above-mentioned drawbacks and improves the quality of the present invention.The present invention solves the above-mentioned drawbacks and makes it even better.The present invention is aimed at initially filling the damaged area by controlling the flow rate of the filling material so that the filling material is brought into contact with the damaged area without being forcefully inserted. The filling material is gradually injected into the space created on the back side of the sewer pipe, and the flow rate control is switched to pressure control, and the pressure is set lower than the damage pressure of the repair member to prevent damage caused by the filling material. This is how it was done.

0,81 to the valve controller 63, the flow rate decreases, and when the B liquid pressure input reaches the set pressure, the pump enters pressure control, the pump operation becomes slow, and the parallel comparison type It will stop after the time set by the exchanger. This allows a fixed amount of filler to be injected into the damaged area, and the pressure at which the filler operates is controlled to prevent further damage to the damaged area. After the repair, the water stoppage condition of the repaired area will be inspected using the TV camera (Figure 3).
