Description

Non-excavation total repair system and construction method using main holder {METHOD AND SYSTEM FOR ENTIRE REPAIRING WITH NON-EXCAVATION TYPE USING MAIN HOLDER}

The present invention relates to a non-drilling overall repair system and construction method using a main holder, and more specifically, to perform the overall repair of a pipe in a non-drilling form, but by using a main holder, the tube side, which is a lining material installed in a pipeline such as water and sewage, Using a main holder that prevents overlapping or wrinkles, improves curing efficiency, and shortens the overall construction time, thereby reducing construction costs associated with repair work for non-excavated pipes, as well as improving construction efficiency. It relates to the non-excavation overall repair system and construction method.

In general, various water and sewage pipes buried in the ground gradually deteriorate over time, and corrosion occurs in the case of water supply pipes, causing a huge amount of water leakage, and rust occurs in the pipe or rust flows into the pipe. In the case of contamination, drinking water is contaminated, and in the case of a sewage pipe, there is a problem of contaminating the living environment because the sewage flows out of the pipe due to cracks or damage, or groundwater inflow and outflow, which pollutes the soil as well as groundwater and causes sinkholes.

In this way, the old buried pipes related to water and sewage, which have been damaged such as cracks, damage, or groundwater inflow and outflow, are repaired. Compared to the initial method of replacing pipes by excavation, efficiency and economy can be pursued. Most of the non-drilling pipe repair method is used.

The non-excavation type pipe repair method is a method of not digging the ground, and is a method of forming a new composite pipe in the water and sewage pipe by inserting the tube into the old buried pipe where cracks, damage, or groundwater inflow and outflow, etc. This is a construction method that can achieve many advantages in terms of constructability, reliability and economy compared to the excavation method.

Incidentally, the non-drilling pipe repair method is to attach a tube impregnated with a thermosetting resin inside the pipe by traction, reverse insertion, placement, and bonding, and then hardening. It is applied to areas where cracks or damage on the buried pipe side or inflow and outflow of groundwater occur. It is a construction method that prevents water and sewage flowing through the pipe from flowing out to the outside by repairing the entire pipe by attaching the impregnated tube. In Korea, the traction method and the reversal method are mainly used.

In the reversal method, a tubular lining material with a resin-impregnated surface is formed on the inner surface, and a tubular lining material coated on the outer surface is installed by traction inversion inside the pipe, that is, the coating surface becomes the inner surface and the resin-impregnated surface becomes the outer surface. It is a method of hardening by applying steam heat while in close contact with the inside of the pipe.

In addition, in the traction method, a tubular lining material with a coating layer formed on the inner surface and a surface impregnated with resin on the outer surface is traction and inverted into the pipe, and then air pressure or steam is supplied to the inside of the tube to expand and expand the outer surface of the pipe. It is a method of hardening the tubular lining material by supplying steam heat while being in close contact with the inner surface.

However, in the conventional non-excavation type pipe repair method, in the traction method construction, there is a disadvantage in that the occurrence rate of overlapping or wrinkles is high when the tube is installed in the pipe, and when the condensate is high, there is a drawback that hardening is difficult during heating and curing due to the condensate water.

In addition, the traction method of the conventional non-excavation type pipe repair method has a problem that the overall construction time is lengthened and the cost is high because it takes a lot of work time and hardening time according to the total repair.

Therefore, when the condensed water is heated, it is easy to harden the corresponding portion of the lining tube 300, and the heated condensate is generated as steam, thereby generating an effect of helping hardening of other parts. The temperature sensor 1340 may control the heater 1320 not to be heated above a certain temperature (eg, 70° C. or more), and measure the condensate temperature.

The camera 1400 is provided on the top of the front body 1100a of the body 1100 to photograph the inside of the lining tube 300 while the air circulation and condensate heating device 440 is moving, and is provided outside of the pipeline. It is transmitted to the device input and monitoring vehicle 430.

The camera 1400 is provided in a rotatable structure, so that it is possible to take a picture of the internal state of the repair tube as a whole. For smooth shooting, the body 1100 may be equipped with a light such as an LED.

The air packer 1500 is mounted in a ring shape at the rear of the body portion 1100, and supplied when a wrinkled portion or an excited portion of the lining tube 300 is found based on the image photographed through the camera 1400 It is a component for flattening the corrugated area or the excited area by being expanded by steam or compressed air.

When the lining tube 300 is inserted into the conduit for repair of the conduit in the repair area, steam is injected into the lining tube so that the lining tube is in close contact with the inner circumferential surface of the conduit to be hardened. In this case, the lining tube may not adhere to the inner circumferential surface of the conduit due to damage to the inner circumference of the conduit or other various causes, and wrinkles or excitation may occur. When a wrinkled portion or an excited portion is found through an image photographed by the camera 1400, the wrinkled portion or an excited portion may be flattened through the air packer 1500.

Specifically, when the air packer 1500 is used, compressed air is supplied to the air packer 1500 in a state in which the rear portion of the body portion 1100 is aligned with the corrugated portion or the raised portion in a vertical direction. By injecting, the air packer is inflated. The expansion of the air packer 1500 is performed to such an extent that the air packer 1500 is in close contact with the lining tube 300 to the inner circumferential surface of the maintenance area duct. At this time, it is also possible to inject high-temperature steam into the air packer 1500 instead of compressed air to help harden the lining tube. When the air packer 1500 is expanded through steam, it is possible to assist the hardening of the lining tube by the temperature of the steam.

The air packer 1500 may be designed in a structure that expands more toward the upper side than the lower side, and is designed so that the width in the center direction is larger than the width at the lower side, so that the air packer 1500 is maximized. Even if it expands, it is possible to prevent the wheel 1120 from being floated on the lower surface.

The reason why the air packer 1500 has a ring shape is that air is circulated through the penetrating portion of the ring and at the same time, the body portion 1100 of the air circulation and condensed water heating device 440 and the camera 1400 are circulated through the penetrating portion of the ring. ), an air circulation unit 1200, a cable for supplying power to the condensed water heating unit 1300 and transmitting and receiving a control signal, and a supply pipe for supplying steam or compressed air to the air packer 1500. .

The air packer 1500 may have a two-separable structure in which two semicircular structured split bodies are arranged vertically or left and right to form one ring shape, or a four-separated structure consisting of four split bodies in the top, bottom, left and right to form one ring shape. You can also have In this case, compressed air or steam may have an individual supply structure for each division.
