Description

TECHNICAL FIELD [0001] The present invention relates to an unfilled pipe filling method and an unfilled pipe filling method for preventing subsidence and settlement of a ground,

More particularly, the present invention relates to an insoluble tube filling method for preventing the sinking and settlement of a ground by injecting a filling material into an insoluble tube that has been left in the ground for a long time. It is an insoluble tube filling method and an insoluble tube filling device.

Recently, the incidence of sink holes in urban areas is increasing. The main cause of the sinkhole in the urban area is found to be caused by groundwater depletion due to groundwater development and soil depression due to the destruction of the aged closed pipe.

In this case, sink hole due to lowering of groundwater level is filled in the sink hole to repair the sink hole. In case of destruction of the closed pipe, it is preferable to remove the closed pipe. However, , The sink hole is being repaired by filling the gutter with the gravel without the demolition of the closed pipe.

However, repairing the sink hole by filling up the gravel has a problem that the gravel particles are removed due to rainfall and the sink hole recovers as the gravel soil sinks. Therefore, it is urgent to take countermeasures to prevent occurrence of a sink hole in an urban area.

In recent years, techniques for reinforcing closed pipes have been carried out by filling a filling material in place of soil in a closed pipe that is piped to the ground and curing the filling material.

As a prior art of the present invention, Korean Patent Registration No. 10-0907434 discloses a method for closing an aged water pipe or sewage pipe.

Specifically, the prior art is a technology for preventing the depression of the insoluble tube by filling a filling membrane filled with soil or sand mixed with water by injecting a high-pressure pump by installing a shielding film with a civil engineering sheet such as a geotextile on the closed pipe side.

However, the prior art has a problem in that the filling material can not be completely injected as the air or water existing in the closed tube is not discharged to the outside of the insoluble tube during the filling process of the filling material.

In order to solve the above problems, Korean Patent Registration No. 10-1592396 discloses a technique for discharging water or air inside a closed tube by providing a discharge port on the opposite side of the filling material inlet.

However, since the filling material is injected in the vertical direction of the closed pipe, there is a limit that air or water can remain in the filling material when the filling material is injected.

That is, the operator confirms the filling of the filling material by confirming that the filling material overflows with the first discharge pipe 510 and the second discharge pipe 520. At this time, the worker may bypass the overflowed filler to the filler supply unit 200 by connecting the return pipe to the first discharge pipe 510.

Meanwhile, in the step of injecting the filler, a pressure gauge (not shown) may be installed in the injection pipe 400 or the discharge pipe 500 to inject the insoluble pipe 100 while assuming the state of the insoluble pipe 100 as a pressure gauge.

When the filler material is injected, it is possible to maintain a constant pressure. In the case of a slight increase in the pressure value, it is possible to estimate the case where the channel meets the filtrate and foreign substances in the downward direction and the inside or inside of the pipe. . Also, by using a pressure gauge, it is possible to prevent the breakage due to the impact caused by the pressure in the pipe.
