Description

Packed tilting apparatus and method for lateral lining (PAL)}

The present invention relates to a non-excavation repair method of the sewage pipe and branch pipe joints, and more specifically, to the sewer pipe and the branch pipe joint that allows for quick repair of the joints of the sewer pipe and the branch pipe connected to the sewer pipe without excavating the ground. It relates to a non-excavation repair device and a repair method.

In general, as a method of repairing the sewer pipes buried underground, a method of replacing the pipe itself after excavating the ground or road has been widely used.

However, the repair of such sewage pipes has several problems.

Since traffic must be blocked before the construction period, traffic jams are caused by long-term road control of 15 to 30 days.

Sewage outflow due to pipe breakage and poor joints contaminates soil and groundwater. Inflow of groundwater reduces the efficiency of sewage treatment plants and causes environmental problems such as large amounts of construction waste.

Complaints arise from intermittent renovations, resulting in administrative distrust, and unforeseen emergency repairs hinder long-term planning.

In addition to the maintenance and direct construction of sewage pipes, indirect construction such as temporary equipment is required, which is uneconomical in view of the cost of construction.

Since it simply replaces the concrete sewer pipe, the chemical resistance is weak and easily corroded again, and the aging progresses rapidly, and thus there is a problem of renovation.

It causes ground subsidence due to the excavation of the ground or road, and there is a risk of damage of other buried pipes such as gas pipes during the excavation.

There is a fear of safety accidents of workers and residents due to excavation work.

It is necessary to reorganize the ground and resurfacing the road after construction, thereby reducing the life of the road.

There is a problem in that the air is longer because a separate work is required to secure the precision construction and watertightness of the joint of the replaced sewage pipe.

Therefore, in recent years, a technique for repairing sewage pipes without digging ground or road has been developed and widely used.

In addition, in the case of sewage pipes with a diameter of less than 800㎜, the law stipulates that workers cannot enter the sewer pipes and work, and therefore, a remote control sewage pipe non-excavation repair device is used.

As a conventional non-excavation repairing apparatus and method for sewage pipes, a tube-type lining tube is placed on the inner circumferential surface of an old sewage pipe without a worker entering the sewer pipe, such as Korean Patent Nos. 0433060, 0555026, 0615070, and 0921481. It is known to coat.

The lining tube is composed of a polyester felt layer and a polyester film layer in close contact with the inner peripheral surface of the sewage pipe, the felt layer is coated with a thermosetting resin. The thermosetting resin coated on the felt layer is in an uncured state and is coated on the felt layer and is impregnated in the felt layer.

In the process of manufacturing the lining tube, the polyester film layer forms an outer layer, the felt layer is manufactured in a state forming an inner layer, it is prepared in this state.

In constructing the conventional non-excavation repair structure of the sewer pipe, the sewer pipe lining tube is inserted into the existing buried sewer pipe through the sewer manhole, and is inserted into the existing buried sewer pipe while reversing by an inverting device.

As for the sewer pipe lining tube inserted into the existing buried sewer pipe, the felt layer forming the inner layer is inverted to the outer circumferential layer by the above-mentioned reversal, and is in close contact with the inner circumferential surface of the existing buried sewer pipe, and the polyester film layer forming the outer circumferential layer is the inner circumferential layer. It is inverted to form an inner circumferential surface in which the sewage contacts with the repair completed.

When the lining tube is inserted into a predetermined section of the existing buried sewer pipe to be repaired, for example, a section between the manhole and the manhole, heat-curing water is injected into the inside of the lining tube to form a filter layer, a thermosetting resin, and a polyester film layer. As it is heated, it hardens in a state of being in close contact with the inner circumferential surface of the existing buried sewage pipe.

When curing of the lining tube is completed, the construction is completed by cutting the front end and the rear end of the lining tube.

On the other hand, the sewage pipe is typically connected to a plurality of branch pipes connected to the sewage source of the home, building, or factory, the lining tube is also installed in the branch pipe joints, so that the lining tube after the curing is completed corresponding to the branch pipe joints The lining tube is cut and drilled in the part so that the sewage discharged from the drainage source through the branch pipe is introduced into the sewer pipe.

Such a branch pipe is generally designed to drill the branch pipe joining hole 1a into the sewer pipe 1 and to insert the end of the branch pipe 2 into the branch pipe joining hole 1a, and basically, FIG. 71. As shown in (a) of the drawing, the end of the branch pipe 2 should be correctly joined to the branch pipe joining hole 1a of the sewer pipe 1.

In addition, depending on the construction environment and the construction skill of the contractor, as shown in FIG. 71 (b), the tip of the branch pipe 2 protrudes inward from the joint hole 1a of the sewer pipe 1 into the sewer pipe 1. It may be constructed in the condition that it is. In this case, before repairing the sewer pipe 1, a traveling robot (not shown) equipped with a cutter is inserted to cut the protruding portion of the branch pipe 2, and then the sewer pipe 1 is repaired. .

However, depending on the construction environment and the construction skill of the contractor, as shown in FIG. 71 (c), the end of the branch pipe 2 is not precisely joined to the branch pipe joint hole 1a of the sewer pipe 1, but there is a gap. In most cases, the branch pipe 2 is formed as shown in (d) of FIG. 71 as time elapses after the construction even in the case of precise construction, as shown in FIG. 71 (a). And the branch pipe joint hole (1a) part is corroded to create a gap in the joint between the branch pipe joint hole (1a) and the branch pipe (2) of the sewage pipe (1), in which case the sewage pipe (1) is a sewer pipe lining tube ( Even if it is repaired by 3), the gap between the junction pipe joining hole 1a of the sewer pipe 1 and the branch pipe 2 is not filled, so that the sewage which should be discharged from the branch pipe 2 and flowed into the sewer pipe 1 should be discharged. Is leaked into the gap of the junction, which contaminates the soil of the surrounding ground. .

Therefore, in the related art, an apparatus and a method for repairing the joint between the branch pipe 2 and the branch pipe joining hole 1a have been developed.

The central axis of the packer 20 is coaxial or parallel to the branch tube axis by the first axial and the second axial compound sliding operations.

[Packer Insertion Step]

The packer inserting means 50 is operated in an insertion mode by a remote control from the outside of the sewer pipe 1 so that the tilted packer 20 is inserted into the branch pipe 2 to be coaxially or parallel to the branch pipe 2. (See FIG. 34).

At this time, when the packer 20 starts to be inserted into the branch pipe 2, the spherical fixture 46a is operated in a disengaged mode so that the endless tilting operation by the packer endless tilting means 40 can be performed. When the branch pipe 2 and the packer 20 are not coaxial or parallel, the packer 20 is endlessly tilted by the contact force between the inner circumferential surface of the branch pipe 2 and the tip flange 22 of the packer 20. The packer 20 is inserted in coaxial or parallel with the branch pipe (2).

In addition, because the packer 20 is coaxially or parallel to the branch pipe 2, the packer 20 is formed by the packer automatic adjustment means 70 together with the packer stepless tilting means 40. Coaxial or parallel to the tube 2 is made more smoothly so that the packer 20 can be smoothly inserted into the branch pipe (2) without moving forward or backward the remote control vehicle (10). .

Insertion of the packer 20 is the branch pipe lining sheet (S) and the uncured resin (R) wound on the outer circumferential surface of the cylindrical portion 21 is the inside of the branch pipe (2), sewage pipe (1) and branch pipe (2) It is set as the state located over the junction part of the ()) and the inner peripheral surface of the sewer pipe (1).

[Air injection stage]

When the insertion of the packer 20 into the branch pipe 2 is completed, by injecting air into the packer 20 by a remote control from the sewer pipe 1, the cylindrical portion 21 is expanded As a result, the branch pipe lining sheet S wound around the cylindrical portion 21 is expanded to be in close contact with the inner circumferential surface of the branch pipe 2 (see FIG. 35).

At this time, the uncured resin (R) coated on the outer circumferential surface side of the branch pipe lining sheet (S) of the inner circumferential surface of the branch pipe (2), by the expansion force of the packer 20, of the sewer pipe (1) and branch pipe (2) It is crimped | bonded between the junction part, the inner peripheral surface of the branch pipe joining hole 1a of the sewer pipe 1, and the inner peripheral surface of the perforation part of the sewer pipe lining tube 3, and the branch pipe lining sheet S.

The branch pipe lining sheet S and the uncured resin R wound around the cylindrical portion 21 of the packer 20 are extended and bent outward to be in close contact with the inner circumferential surface of the sewer pipe lining tube 3. Accordingly, the branch pipe lining sheet S and the uncured resin R are formed on the inner circumferential surface of the branch pipe 2, the joint portion of the sewer pipe 1 and the branch pipe 2, and the branch pipe joining hole 1a of the sewer pipe 1. The inner circumferential surface is brought into close contact with the inner circumferential surface of the perforated portion of the sewer pipe lining tube 3 and the inner circumferential surface of the sewer pipe lining tube 3 (magnification of enlargement in FIG. 35).
