Abstract

The present invention relates to a device for injecting a resin liquid-impregnated PE soft nonwoven reinforcement tube used to regenerate an old sewage pipe by a PE soft nonwoven reinforcement tube insertion method into an old sewer pipe by air pressure or water pressure. More specifically, when rehabilitation of aging sewer pipes, the scale and dirt inside the aging pipes are removed, and the tubular and dried PE soft non-woven reinforcement tubes impregnated with thermosetting resin solution are inserted into the water pressure or air pressure. By reducing the weight of the work process, and reducing the cost of expensive PE soft non-woven reinforcement tube to reduce the construction cost and improve the work process. Conventional methods for inserting such a thermosetting resin-impregnated PE soft nonwoven fabric reinforcement tube into an old sewer regeneration tube have been constructed by two methods: a hydraulic reversal insertion method and an air pressure reversal insertion method. Conventional hydraulic pressure reversal insertion method puts the iron support tower on the ground at the construction site, and installs the water pipe vertically here, and continuously fills the water in the water pipe to invert the resin liquid-impregnated PE soft non-woven reinforcement tube at the pressure of head pressure. As it is inserted, it is easy to be exposed to electric shock of grounded high voltage cable, traffic hazard and strong conduction due to strong wind, and the head pressure and insertion distance are directly proportional. In the conventional method, the pneumatic reversal inserting device has a resin-impregnated PE soft non-woven reinforcement tube wound in advance in the winder inside the device to fix the inlet tube, and then blows compressed air (FIG. 7) into the sealed device to form a balloon-like shape. It can be inserted in the old pipe by inverting it into the old pipe. The long distance can be inserted by adjusting the compressed air. However, the 80 ~ 100m impregnated tube should be wound around the device in advance so that the device becomes large and the weight of the resin impregnated tube In addition, the weight is so heavy that the vehicle mounted with the reversing device becomes large, and the sewer work manhole is not accessible, so that the loss of expensive thermosetting resin-impregnated PE soft nonwoven reinforcement tube is generated, which causes heat during the heat curing operation. Many losses occur and become uneconomical. In addition, there is a disadvantage that a large work vehicle occupies the road of the construction section for a long time, causing traffic obstacles.

Accordingly, the present invention has the advantage of inventing a pneumatic-hydraulic composite reversal insertion device and using reversal insertion according to the purpose of construction. In addition, the reversal insertion device of the present invention is lighter and smaller in size, so that the reversing device can be installed in the manhole or the construction excavation work area, thereby completely reducing the loss of expensive thermosetting resin liquid-impregnated PE soft nonwoven reinforcement tube and curing process. In the meantime, the heat loss is reduced to satisfy the economics and the efficiency of the construction.

Description

Thermo-resin-impregnated PE soft nonwoven fabric reinforcement tube insertion and repair method for sewage old pipe using pneumatic / hydraulic reverse type reversal insertion device. {A repairing method for used wastewater pipe with thermosetting resin immersion PE soft textile using air and water pressure-driven turn inside out insertion device.}

The present invention is a thermosetting resin soft impregnated nonwoven reinforcement tube with a thermosetting resin liquid impregnated PE soft nonwoven reinforcement tube used to regenerate an old sewer pipe with a PE soft nonwoven fabric reinforcement tube insertion method by a pneumatic / hydraulic composite reversal insertion device inside an old sewer pipe. It is a device for reversing and reversing the insert, and is particularly used for the insertion method of PE soft nonwoven reinforcement tube of sewer pipe regeneration.

Such a device can achieve the purpose of the old sewer pipe rehabilitation work by using both air pressure and water pressure as one device, and it is lighter and smaller than the conventional reversal insertion device, thereby improving workability of the construction, and expensive thermosetting resin. Reduces the loss of liquid-impregnated PE soft nonwoven reinforcement tubes to increase economics.

Conventional reversal insertion methods for PE soft nonwoven reinforcement tubes include hydraulic reversal type (FIG. 8) and pneumatic reversal type (FIG. 7), both of which have larger apparatuses. However, the conventional two methods are disadvantageous due to the risk and inefficiency depending on the construction site conditions.

Conventional hydraulic pressure reversal insertion method (Fig. 8) is to excavate the sewer pipe manhole or ground to establish a steel support on the ground of the work tool cutting the old pipe, and to fix the filling pipe vertically in the center of the support, and then the PE soft non-woven reinforcement tube in the filling pipe Put the tip of the tube over the inlet and fix it, and then supply water continuously to the appendix, and insert the tube upside down by the head pressure of the appendix. Since the height of the steel tower support increases according to the insertion length of the tube, it is exposed to a high-voltage electric shock risk, a traffic obstacle risk, and a danger of falling due to strong winds, and it takes a lot of manpower and time due to the trouble of preparation and dismantling.

In addition, the conventional pneumatic reversal insertion method is pre-wound the resin liquid impregnated PE soft non-woven reinforcement tube in the winding machine inside the reversal inserting device to fix one end of the tube by inverting the tube at the inlet of the reversing inserting device and then Compressed air is blown into the compressor and the tube is inverted to inflate like a balloon and inserted into the old tube. In this method, a thermosetting resin-impregnated PE tube has to be pre-wound inside an inverting inserter, so a long resin-impregnated tube of 80 to 100 M needs to be wound in a winder inside the apparatus. Due to the large size of the tube winding device, the weight of the reversal inserting device is also very heavy, resulting in excessive investment of the facility, and the operation vehicle equipped with the reversing inserting device is impossible to enter the narrow area, thus limiting the rehabilitation of the sewer pipe. do. In addition, since the reversal insertion device cannot be installed inside the manhole of the rehabilitation pipeline or the ground excavation work area at the construction site, the reversal installation must be performed from the ground. It is uneconomical because the loss of the thermosetting resin liquid impregnated PE soft nonwoven reinforcement tube is high, and the high temperature steam for curing is unnecessary when the thermosetting resin liquid impregnated PE soft nonwoven reinforcement tube is exposed and lost. Therefore, since the heat is radiated to the atmosphere, the hot steam consumption increases accordingly. As a result, the fuel loss is increased, the working time is long, the construction cost increases.

To this end, the present invention is to install a lightweight, miniaturized pneumatic-hydraulic hybrid reversing insertion device inside the sewer manhole or inside the working digging, and inverted the thermosetting resin liquid impregnated PE soft non-woven reinforcement tube in close contact with the entrance of the sewer old pipe subject to rehabilitation It was made possible. The pneumatic / hydraulic combined reversal insertion device is composed of a pressure resistant structure of horizontal cylindrical steel, and the thermosetting resin liquid-impregnated PE soft nonwoven reinforcement tube is inserted into the device through the tube supply valve (4) at the rear of the reversal insertion device. The end of the tube is mounted upside down on the tube connector 8 on the front side, and then the pneumatic-hydraulic hybrid reversing insertion device is brought into close contact with the entrance of the retirement old pipe. Pneumatic-hydraulic composite reversal insertion device (FIG. 1) is a resin-impregnated tube supplied from the rear of the device automatically while the tube is reversely inserted by the compressed air or pressurized water 27 supplied to the compressor or pump therein. The tube is inverted and inserted without a supply aid by being drawn in and allowing the resin liquid impregnation tube to be continuously supplied. At this time, the compressed air or pressurized water injected into the reversing insertion device is prevented from leaking to the outside of the reversing insertion device by the tube supply valve (4) for introducing the tube into the device, and the thermosetting resin solution impregnated PE soft nonwoven fabric reinforcement tube By developing a tube feed valve drawn into the tube, the tube reversing inserter has been miniaturized and lightened, and installed inside the work manhole to enable work. This reduces the loss of the thermosetting resin-impregnated PE soft non-woven reinforcement tube, reduces the manufacturing cost of the reversal inserting device, prevents the resin-liquid impregnation tube from being detected in the winder in advance, and reduces the work process and minimizes the exposure of the PE soft non-woven reinforcement tube to the outside of the tube. Therefore, it is possible to insert long-distance by increasing reverse pressurization and minimize heat loss during hardening, thus increasing construction economics and reducing construction cost.

The present invention is to simplify the apparatus for miniaturizing and lightweighting the thermosetting resin liquid impregnated PE soft non-woven reinforcement tube by inverting and inserting the tube inside the old pipe of the sewer retirement construction by using water pressure or air pressure. To this end, the tube supply valve using the characteristics of the fluid pressure transfer in the sealed container is moved to supply the impregnated tube in the axial direction of the resin liquid impregnated PE tube (Fig. 6b) while the fluid injected into the inverting insertion device is PE by the pressure The PE film on the surface of the soft nonwoven reinforcement tube and the gap between the tube supply valve 4 are brought into close contact with each other to block the autism so that no leakage occurs. Such a tube supply valve is made of elastic rubber or synthetic resin material, which is installed on the rear of the reversal insertion device of the present invention, and the front of the device is a cylindrical pressure-resistant structure configured to invert a thermosetting resin liquid impregnated PE soft nonwoven reinforcement tube to be fixed to the device. A simple tube reversal insertion device is invented.

The principle of operation is that when the fluid is pressurized within the enclosure, the fluid delivers the same pressure to the wall of the enclosure, so that the fluid pressure injected inside the tube-mounted reversal insertion device can Pressure is applied to the elastic rubber plates 3a and 3b). Then, the rubber plate of the tube supply valve closes the PE soft film on the surface of the tube and closes it to prevent the leakage of fluid pressure. Therefore, as the pressure applied to the inside of the device increases, it pushes the tube toward the front of the reversal insertion device and inflates like a balloon. It is flipped over and inverted to move forward. The tube (FIG. 6b) mounted through the tube supply valve installed at the rear of the reversal insertion device has a pressure applied to the injected fluid in the axial direction and the front direction of the reversing device, and the tube reversing device front direction has a wide tube area. As the pressure is expanded, the injection pressure acts as a force proportional to the area, and the axial direction of the tube is a cross-sectional structure with almost no area under pressure. Inverted and inverted, the feed tube pulls in from the outside to the inside without great resistance. At this time, the friction between the rubber plate of the tube supply valve at the rear of the device and the PE film on the surface of the PE soft non-woven reinforcement tube is reduced so that the tube can be easily supplied with water to be inserted into the old pipe to prevent tube damage. . At this time, the model of the resin liquid impregnated PE soft non-woven reinforcement tube supplied in the device is supplied in the form of a flat plate that is flatly pressed because the resin solution is impregnated into the inner non-woven fabric layer. When it is inserted into the rehabilitation tube, the tube is inflated, and in the form of a cylindrical pipe, the inner resin solution-impregnated part and the outer PE film part are inverted to enter the renovation tube without any resistance at all.

In view of the above, the configuration of the present invention will be described with reference to the accompanying drawings.

1 is a schematic perspective view of a reversal insertion device for a PE soft nonwoven reinforcement tube of the present invention, the model of which is made of a steel of a horizontal cylinder, the front surface of which is welded by a steel sheet plated with a hard plate, and the center of the tube is overturned It is welded with pipe to be fixed by bend (8), and the back of the cylinder is a light plate structure welded with a hatch-type wrench, the tube supply valve (4) is installed horizontally at the center, and a rubber-coated wire rope at the top of the center of the light plate. Alternatively, a rubber-coated wire rope supply valve (3) is installed to control the rate at which the hot water circulation hose is supplied into the reversal insertion device, and the main body and the hinge (10) are attached to one side of the welded hatch type flange. It is a form of pressure-resistant structure that can open and close the back.

The tube supply valve 4 has a structure similar to the schematic perspective view and sectional view of FIG. 3A (FIG. 3B), and the material of the valve is made of elastic rubber or synthetic resin, and the hole 11 inside the valve allows the tube to pass through the valve. It is a structure that supplies water to the inside for lubrication during supply movement. The tube feed rate regulator 9 in the center portion of the tube feed valve adjusts the rate at which the PE soft nonwoven reinforcement tube is fed to control the tube from being tightly inserted and wrinkled when the PE soft nonwoven reinforcement tube is supplied. There is a control device that installs a rubber tube to inflate air into the rubber tube and pushes up and down the tube feed valve to apply pressure to control the tube feed rate. A valve (1) for supplying and a valve (2) for supplying steam or hot water are installed, and a connecting pipe (not shown) for measuring the pressure and temperature inside the reversing insertion device is installed. A towing ring (not shown) is welded to the unit to tow into the manhole or tool It is a structure.

Referring to the operation sequence of the PE soft nonwoven fabric reinforcement tube reversing insertion device of the present invention by inserting the PE soft nonwoven reinforcement tube immersed in the resin liquid through the tube supply valve 4 as shown in Figure 6a Insert the tube upside down into the tube fixing pipe (8) as shown in Figure 6a and tightened with a bend to secure the tube does not fall off and leaking air or water. When the tube is fixed, it is placed in an excavated work tool using cranes or chain blocks, and is fixed by being close to the cut portion of the regeneration pipe. Then, the compressed air or pressurized water is connected to the valve 1 to be supplied into the reversal inserting device. As shown, the resin-impregnated PE soft nonwoven reinforcement tube is swollen and inverted like a cylindrical balloon such as a rod to the front of the apparatus so that the tube is inverted into the old pipe reinforcement tube and enters without resistance. The PE soft non-woven reinforcement tube is compressed air into the tube feed rate regulator (9), which is a control device installed in the tube feed valve to maintain a constant feeding pressure of air or water in order to insert wrinkle-free, and to maintain a constant feed rate of the tube. Adjust the speed of the PE soft nonwoven reinforcement tube by adjusting it properly.

If the thermosetting resin-impregnated PE tube is inserted in half of the length of the construction section, stop the insertion as shown in FIG. 6C, depressurize, open the hatch-type trench at the rear of the reversal insertion device, and open the last end of the tube from the tube supply valve. ), And put the steam exhaust valve kit (Figs. 5a and 5b) at the end of the tube as shown in Fig. 6c and tie it with a rope or the like and seal it so that compressed air or pressurized water is not leaked, and then rubber coated wire rope or hot water hose supply valve (3) Connect the rubber coated wire rope or hot water hose through the inside, close the hatch type flange, tighten it with the fastening bolt (7), and press the compressed air again to invert the tube. At this time, the insertion speed of the tube is inserted into the rubber-coated wire rope or hot water hose supply valve (Fig. 4) to control the speed so that the inverted insert at a constant speed. When the inverted insertion fluid of the tube is water (Fig. 6e), the end of the resin impregnated tube is tied with a rope and sealed, and the end of hot water hose is connected to the rope of appropriate length to adjust the insertion speed of the tube. After use, switch to hot water circulation lake. After removing the tube from the tube supply valve (4) by inserting a tube supply valve plug 30 equal to the cross-sectional size of the tube to maintain the airtight inside the inverter.

When the insertion of the tube is completed by blowing compressed air, the state becomes as shown in FIG. 6d, and the pressure is kept constant, and the steam valve 2 is connected to the boiler steam line to supply steam into the tube. In order to smoothly supply the steam, the valve of the steam exhaust valve kit 29 attached to the end of the inversion tube is operated to harden the impregnated thermosetting resin liquid with high temperature steam heat while maintaining the pressure inside the thermosetting PE soft nonwoven fabric reinforcing tube.

The effect of the present invention configured as described above includes the tube inserting device of the thermosetting resin solution impregnated PE soft nonwoven fabric reinforcement tube of the sewer pipe reinforcement pipe miniaturization and streamlined process to reduce the manpower and time of preparation work. It has an economic effect of reducing the loss of expensive resin liquid impregnated PE soft nonwoven fabrics.

Conventional hydraulic pressure reversal insertion method can reduce the time and manpower of the preparation and dismantling work to install the steel tower structure and the appendage pipe on the ground of the manhole or construction excavation point. In addition, the hydraulic pressure reversal insertion distance is proportional to the head pressure of the appendage pipe, so a very high appendage pipe is installed in the long section construction. For example, in order to insert the hydraulic pressure reversal at the pressure of head pressure of 1 kg / ㎠, the height of the water pipe of the steel tower structure should be about 10 m. However, if the reverse insertion device of the present invention is used, the pressure of the 1-stage volute pump of 1 kg / ㎠ You can insert a reverse channel.

In addition, the conventional pneumatic reversal inserting device has to be pre-wound after the resin liquid impregnated PE soft nonwoven fabric reinforcement tube, and is mounted in the vehicle because the volume and weight of the device are heavy, and from the pneumatic reversal insertion of the tube to the completion of curing of the tube. Since the road occupies the road for a long time, the traffic is disturbed, and since the inverted vehicle is not accessible to the work area between construction zones, the PE flexible nonwoven fabric has a pneumatic pressure because the inverted insertion tube has to be inserted Z-shaped from the ground to the work area (Fig. 7). The distance from the reverse inserter to the entrance to the construction rehabilitation pipe is lost. The reverse inserter of the PE soft nonwoven fabric reinforcement tube of the present invention has a small volume and weight, so that the loss of expensive resin liquid-impregnated PE soft nonwoven tube is installed inside the work tool. It can be completely reduced, and construction can be performed without having to occupy the road by a large inverter vehicle in the construction work area.

In addition, the conventional method is constructed with a device for the hydraulic pressure reversal and the air pressure reversal method, respectively, it is a useful sewer pipe rehabilitation method can be used according to the purpose and characteristics of the sewage old pipe rehabilitation construction with one reversal insertion device of the present invention.
