Abstract

PURPOSE: A method and a device for molding a liner are provided to supply the liner to an old waterwork pipe by melting and molding the liner carried after cut into unit length at a regenerating field. CONSTITUTION: To mold a liner for an old waterwork pipe(70), a cut and carried liner(60) is moved at the same speed as the liner transferred by a winch cable(80) to be readily inserted in the old waterwork pipe. The cut liner is melted on an end of the previously melted liner. A melting portion(61) of the liner is ground. The continuously melted liner is heated at 100 to 120deg.C by a heater to be readily molded and is folded in a U shape. The hot liner is cooled up to 60deg.C not to be damaged by the tracking force of the winch cable. A liner folding molder is comprised of an upper pressurizing roller unit for gradually depressing an upper part of the liner to be readily inserted; a side pressurizing roller unit for folding the liner in the U shape by pressurizing from the side of the liner; and a planar transfer roller unit for readily transferring the liner.

노후 상수관 갱생용 라이너 절첩성형방법 및 그 성형장치Liner folding molding method for regeneration water pipe

본 발명은 노후 상수관 갱생용 라이너 절첩성형방법 및 그 성형장치에 관한 것으로, 더욱 상세하게는 노후 상수관의 갱생작업 현장에서 일정 길이로 절단되어 운반된 폴리에틸렌제의 라이너를 융착한 후 "ㄷ"형으로 절첩 성형하고, 청소된 노후 상수관에 삽입하여 상기 노후 상수관의 갱생작업을 실시할 수 있도록 한 라이너의 절첩성형방법 및 그 성형장치에 관한 것이다.The present invention relates to a method for folding the old water pipe regeneration liner, and a molding apparatus thereof, and more particularly, after fusion of a liner made of polyethylene cut and transported to a predetermined length at the site for rehabilitation of the old water pipe. The present invention relates to a folding molding method of a liner and a molding apparatus thereof, which are formed by folding a mold and inserted into a cleaned old water pipe so as to perform regeneration of the old water pipe.

일반적으로, 지하에 매설된 상수관은 일정기간 이상 사용하게 되면 부식과 누수현상이 발생되며, 이러한 수도관을 통하여 각 가정에 공급된 수돗물에는 다량의 녹물이 함유되게 된다.In general, the underground water pipes are used for a certain period of time, causing corrosion and water leakage, and the tap water supplied to each household through these water pipes contains a large amount of green water.

그러므로, 일정기간 이상 사용하여 노후된 수도관은 새로운 관으로 교체하여야 하나, 이에 소요되는 비용이 막대하며, 도로굴착으로 인하여 교통에 막대한 지장을 초래하므로 노후된 상수관을 교체하지 않고 상기 상수관에 라이너를 삽입하여 갱생하는 방법이 사용되고 있다. 이때 노후 상수관에 삽입되는 라이너를 노후 상수관에 삽입하기 용이하게 생산과정에서 "ㄷ"형으로 절첩 성형하여 롤 상태로 생산하고 있다.Therefore, old water pipes that have been used for a certain period of time must be replaced with new ones, but the cost thereof is enormous, and since the road excavation causes huge obstacles in traffic, the liner is inserted into the water pipe without replacing the old water pipes. The rehabilitation method is used. At this time, the liner inserted into the old water pipe is folded into a "c" shape in the production process to facilitate insertion into the old water pipe is produced in a roll state.

그러나, 상술한 바와 같이 생산과정에서 "ㄷ"형으로 절첩되어 롤 상태로 생산된 라이너를 갱생작업 현장으로 운반함에 있어서, 라이너의 직경이 작은 경우(약 200㎜ 이하)에는 별 문제점이 없지만 직경이 큰 경우에는 감겨진 상태의 롤 직경이 상당히 커져 옆으로 눕힐 경우에는 도로교통법 상에 제한 차폭에 걸리고, 새워 운반할 경우에는 육교 등에 걸려 갱생작업 현장까지 운반하는데 문제점이 많다.However, as described above, in transporting the liner produced in the rolled state in the form of "c" in the production process to the rehabilitation site, when the diameter of the liner is small (about 200 mm or less), there is no problem, but the diameter is In the large case, the rolled state of the wound state is considerably larger, and when it is laid on its side, it is restricted by the road traffic law.

이에 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 갱생작업 현장에서 단위 길이로 절단되어 운반된 라이너를 융착하여 "ㄷ"형으로 성형하여 노후 상수관에 공급할 수 있도록 함에 본 발명의 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, the object of the present invention to be supplied to the old water pipe by fusion of the liner cut and transported to the unit length in the rehabilitation work site to form a "c" type have.

상기 목적을 달성하기 위한 본 발명은 일정 길이로 절단되어 운반된 라이너를 융착수단에 의하여 연속되게 융착시키고, 상기 융착된 라이너를 노후 상수관에 삽입하기 용이하게 "ㄷ"형으로 성형하여 공급할 수 있도록 한 것으로, 라이너의 운반상의 제약을 받지 않으며, 필요 길이에 따라 라이너를 성형하여 노후 수도관에 삽입할 수 있게 한 것이다.The present invention for achieving the above object is to continuously weld the liner cut and transported to a certain length by a fusion means, and to form and supply the fused liner in a "c" shape to be easily inserted into the old water pipe. In one embodiment, the liner can be inserted into the old water pipe by forming the liner according to the required length without being restricted by the transportation of the liner.

By injecting steam and high-pressure air in close contact with the old water pipe (70) to harden it is to complete the rehabilitation of the old water pipe (70).

한편, 상기 성형과정에 라이너(60)를 "ㄷ"형으로 성형하는 성형장치(10)는 상부 가압로울러부(11)와, 한 쌍으로 이루어진 측면 가압로울러부(12)와 평면이송로울러부(13) 및 한 쌍의 가이드로울러부(14)로 구성되어 있다.On the other hand, the molding apparatus 10 for molding the liner 60 to the "c" type during the molding process, the upper pressurizing roller portion 11, a pair of side press roller portion 12 and the plane feed roller portion ( 13) and a pair of guide roller portions 14.

여기서, 상기 상부 가압로울러부(11)는 가열과정(C)을 통하여 연화된 라이너(60)의 상부가 서서히 함몰되어 용이하게 접혀지도록 하향경사지며 나사축으로 이루어진 승강부(11a)에 의하여 상하 승강되게 되어 결합되어 있고, 상기 측면 가압로울러부(12)는 상기 상부 가압로울러부(11)에 의하여 점진적으로 중앙이 함몰되는 라이너(60)의 측면에서 가압하여 "ㄷ"형으로 절첩되게 한 쌍으로 이루어져 폭이 좁아지게 형성되며 폭조절부(12a)에 의하여 폭조절이 가능하게 결합되어 있으며, 상기 평면이송로울러부(13)는 "ㄷ"형으로 절첩 성형되며 윈치케이블(80)에 의하여 견인되어 노후 상수관(70)으로 삽입되는 라이너(60)가 용이하게 이송되게 결합되어 있는 한편, 상기 가이드로울러부(14)는 가열장치(20)에 가열되어 유입되는 라이너(60)의 유입이 안정되게 측면 상부에 결합되어 있다.Here, the upper pressurizing roller portion 11 is inclined downward so that the upper portion of the softened liner 60 is gradually folded in the heating process (C) and is easily folded up and down by an elevating portion 11a formed of a screw shaft. The side pressure roller part 12 is pressed in the side of the liner 60 which is gradually recessed in the center by the upper pressure roller part 11 to be folded in a "c" shape in a pair. The width is narrowed and is coupled to the width control by the width adjusting portion 12a, the planar conveying roller portion 13 is folded in a "c" shape and is towed by the winch cable 80 While the liner 60 inserted into the old water pipe 70 is coupled to be easily transported, the guide roller portion 14 is heated to the heating device 20 so that the inflow of the liner 60 flows in stably. Side top Is coupled to
