摘要： PURPOSE:To solve the problem that an excess resin deposits and hardens in supply pipes by previously inserting a belt-like mat removably into the pipes and drawing out the belt-like mat when lining of the supply pipe ends at the time of repairing said pipes. CONSTITUTION:The belt-like mat is previously removably inserted into the conduit 1 of the route where the supply pipes 2 are branched at the time of repairing the supply pipes 2 branched from the conduit 1 installed underground. A required amt. of the resin is introduced and run into the respective pipes 2 in this state from the terminal apertures of the respective pipes by which the lining to form the resin film is applied on the inside surface of the pipes. The belt-like mat 50 is drawn out of the conduit 1 upon ending of application of the lining and the excess resin admitted into the conduit from the respective branches of the supply pipes is clung to the mat 50 and is discharged to the outside of the conduit. As a result, the problem that the excess resin deposits and hardens in the conduit is solved and the hindrance of the travel of a pig to be used in the subsequent repair of the conduit side or the like is obviated.

摘要： PURPOSE:To form a lining layer having a uniform thickness without generating a clogging, by shifting air feeding start time of a resin so that resin arrival times from branched pipelines to a lining finished open end are made almost the same. CONSTITUTION:The distances reaching the lining finished open end 41 of a main supply pipe 4 from the supply ports of the resin A of branched pipelines 5-7 are different and the supply of the resin A is started from the branched pipeline 5 long in the distance reaching said lining finished open end 41 in succession and successively transferred to other branched pipelines 6, 7 so as to provide time difference. By this method, lining is simultanesouly finished without clogging communication parts and a lining layer having a uniform thickness is formed.

摘要： PURPOSE:To simply confirm the air-tightness of a supply pipe, by providing a relief valve to the open end of the supply pipe branched to each user and detecting pressure change at the time of the repairing of the pipe interior by the pressure meter provided inside said valve. CONSTITUTION:Supply pipes 2 for guiding gas to users are provided to a conduit 1. In repairing these pipings, said pipes 2 are divided over a proper length L to connect an introduction guide pipe 3 and a lead-out guide pipe 4. In correction, resin lining is formed to each supply pipe 2 to perform repairing of the pipe inner surface. Subsequently, a test unit 9 is connected to each supply pipe 2. This test unit 9 is constituted by forming a pressure meter 92, a relief valve 93 and a throttle opening 94 to a pipe body 91. In the next step, the repairing of the conduit 1 is performed by moving a repairing unit G and the air-tightness of each supply pipe 2 is confirmed by the pressure change of the pressure meter 92 at the opne end of each supply pipe 2 at this time.

摘要： PURPOSE:To perform finish after repairing by removing an obstacle, by discharging a penetrated resin to a supply pipe to smooth the repaired part after repairing the pipe joint part of an existing pipe by using a pig. CONSTITUTION:Pigs 2, 3 are introduced into an existing pipe 1 and a resin C is injected in front of the front side pig 2 while a resin D is injected into the space between front and rear side pigs 2, 3 to repair the pipe joint part. Thereafter, the pigs 2, 3 are drawn by the operation of a traction cable 4 and dusts in the pipe 1 and the pipe joint part X are removed by the stickness of the resin C but the resin D is flowed into the pipe joint part X from a groove by generated filling pressure. On the other hand, air in the connection space of the pipe part X also receives filling pressure and naturally discharged rearwardly. Subsequently, compressed air is supplied to discharge the resin from a supply pipe 40. By this method, perfect finish is performed after the repairing of the pipe joint part.

摘要： PURPOSE: To avoid injection of excessive resin and to dispense with the use of pigs by calculating the length of the pipe from the internal pressure of feeding pipe of compressed air at the stage for feeding compressed air into the pipe to be coated using a blower.
CONSTITUTION: When a blower 5 is driven before the beginning of lining, the compressed air passes to a branch pipe 2 through a feeding pipe 1. If the values of the internal pressure of a sensor 6 are expressed as functions of the diameter of the feeding pipe 1 and the length of the pipe as intrinsic function in a control circuit 8, the length of the pipe is operated from an observed value of the sensor 6, and necessary amt. of resin is operated. The time to be set for a timer 9 is decided by setting the time for injecting the resin using an injection device 10. If, under this condition, the lining resin is injected into a launcher 3 and the resin is conveyed pneumatically by atomizing using the airstream from the blower 5 into the feeding pipe 1, wastless lining on the inside surface of a pipe is executed.

摘要： PURPOSE: To perform perfect repairing work while reducing traction resistance, by providing an embedding plate between a leading end barrel piece and a barrel piece and securing the same to a traction cable.
CONSTITUTION: An embedding plate 39 is provided between a leading end barrel piece 32 and a barrel piece 33 and secured to a traction cable 4 while the support 36 provided to the front end of a pig 3 and the embedding plate 39 are connected so as to clamp the leading barrel piece 32 therebetween by bolts and nuts 38aWd and the embedding plate 39 is connected to the support plate 37 provided to the rear end of the pig 3 by a wire 38 so as to suppress the stretching of the barrel piece 33. By this method, because air-tightness is held in the front side and not only stretching is suppressed but also air-tightness is held in the rear side, repairing work is perfectly realized.
