Description

Sewer pipe non-dig repair device}

The present invention relates to a non-dig repair device for sewer pipes, and more specifically, to prevent civil complaints at construction sites by suppressing noise and road blocking. When a reinforcing tube for repairing a sewer pipe is inserted, the reinforcing tube is not used to repair the sewer pipe. It relates to a non-dig repair device for sewer pipes that is adhered in close contact with the inner surface of the pipe.

Generally, sewage pipes to treat wastewater discharged from homes or businesses, rainwater pipes to discharge rainwater into rivers, or confluence pipes through which sewage and rainwater combine are buried underground. Sewage pipes, rainwater pipes, and confluence pipes are collectively referred to as sewage pipes. It is called a sewer pipe.

A plurality of these sewer pipes are connected and used to move rainwater or wastewater to a sewage treatment plant or river.

However, as sewage pipes age over time, cracks may form, or wastewater may leak to the outside due to cracks, damage, or separation of connections, causing environmental pollution such as soil contamination, as well as sludge or foreign substances flowing in from outside. As this builds up, foreign substances, sludge, sediment, etc. cause foul odor.

The existing sewer pipe repair method involves excavating the entire soil and ground where the damaged sewer pipe is buried and then replacing the damaged sewer pipe itself with a new one. However, replacing the entire sewer pipe with only localized damage is unreasonable in terms of cost. , it also has the disadvantage of not only taking a long time to work, but also greatly reducing workability.

Accordingly, as another sewer pipe repair method, a lining method is used in which localized damage to the sewer pipe is filled with grouting, or when the damaged area is widely distributed and grouting is not possible, a separate repair material is applied to the inside of the sewer pipe.

If repairs are required to target abnormal areas such as partially damaged pipes buried underground, cracks or gaps at the joints of the pipes, or the resin in the repair material shrinks during the hardening process, causing lifting, etc. As a construction method for repairing while buried, first, there is a total repair method that repairs the abnormal area by inserting a synthetic resin pipe as a whole, and second, a bonding material and repair material are used to target only the abnormal area with a bonding material. There is a lining partial repair method that partially repairs by applying and impregnating and then hardening.

As a repair method for underground pipes, non-excavation repair methods that do not excavate around the buried pipe have recently been widely used.

Non-dig repair methods include the traction method and the reverse method. The traction method involves towing a tube-shaped reinforcement tube into an old pipe, then applying pneumatic pressure to the inner diameter of the reinforcement tube to expand it in the outer diameter direction, thereby attaching the reinforcement tube to the inner wall of the pipe. This is a method of heat curing by applying steam into the reinforcement tube while it is in close contact with the tube.

The reverse hole method is a method of inverting the reinforcing tube, inserting it into the pipe, applying pneumatic pressure to bring the reinforcing tube into close contact with the inner wall of the pipe, and applying high-temperature steam to the inside of the reinforcing tube to heat harden it.

Registered Patent No. 10-1729227 discloses a "complete sewer pipe repair system without excavating", and to repair a sewer pipe, a reinforcing tube loading vehicle, a reinforcing tube inversion part, a reinforcing tube insertion means consisting of a compressed air supply part, and steam It consists of a steam supply section consisting of a supply vehicle and a steam generator, and a condensate circulation section that exchanges heat with waste steam for low-temperature condensate generated inside the reinforcement tube and then supplies it back to the reinforcement tube.

Such a sewer pipe reinforcement device must be equipped with an inverter, boiler, generator, etc.

In order to reinforce the sewer pipe, an inverter, boiler, generator, etc. must be installed, so not only is it expensive to reinforce the sewer pipe, but there is a problem that a large number of workers are required to do the work.

In addition, the repair area of the sewer pipe has a protrusion that protrudes into the inside of the sewer pipe and a concave inlet that is recessed into the inside of the sewer pipe, but there is a problem in that the reinforcement tube does not adhere closely to the protrusion and the inlet.

Meanwhile, in order to reinforce sewer pipes, noise is generated from inverters, boilers, generators, reinforcement tube loading vehicles, steam supply awnings, etc., and there is a problem of increasing civil complaints due to such noise, and vehicular traffic on the road during sewer pipe reinforcement work. There is a problem that needs to be limited.

The rotation gear unit 113 includes a motor 114, a reducer 115 that reduces the rotation speed of the motor 114, a drive gear 116 rotated by the reducer 115, and the hot air discharge pipe. It consists of (151) and a driven gear (117) that rotates the tube adhesion unit (152),
The driven gear 117 is formed with a plurality of air tube coupling holes 118 into which the high-temperature air discharge pipe 151 is coupled, and a tube unit coupling hole 119 into which the tube adhesive unit 152 is coupled is formed. Characterized by a sewer pipe non-dig repair device.
According to paragraph 1,
The tube adhesive member 150 includes a high-temperature air discharge pipe 151 that discharges high-temperature air by heating, and the sewer pipe 10 by the tube pressing member 130 while rotating together with the high-temperature air discharge pipe 151. It consists of a tube adhesion unit 152 that pressure-adheres the reinforcement tube 11, which is in close contact with the inner surface, to the inner surface of the sewer pipe 10,
The high-temperature air discharge pipe (151) and the tube adhesion unit (152) are installed to be rotatable by a rotating gear unit (113) installed inside the body member (110).
According to paragraph 4,
The tube adhesion unit 152 includes a fixed angle 153 installed on the driven gear 117 of the rotary gear unit 113, a sliding hole 154 formed at the top of the fixed angle 153, and the fixed angle 153. A spring insertion portion 155 formed on one side of the angle 153, a spring 156 installed inside the spring insertion portion 155, and a pressure rod elastically installed in the spring insertion portion 155 ( 157) and a rotating pressure wheel 160 that presses the reinforcement tube 11 to the inner surface of the sewer pipe 10 by the elasticity of the spring 156. A sewer pipe non-dig repair device comprising a.
