摘要： PURPOSE:To form a lining layer having a uniform thickness, by performing the supply of a lining resin from a pipe the branched position thereof is remotest and starting the supply of said resin while detecting the pressure of the next remote pipe by a pressure detection means. CONSTITUTION:With respect to lining routes reaching the lining finished open end of a main pipeline 4 from terminals of branched pipelines 5-7, the supply of a lining resin is performed from the pipeline 5 of which the branched position is remotest and reaches the branched part of the branched pipe 6 while applying lining. With respect to the next remote one, pressure variation is detected by a pressure gauge 18 to start the supply of the lining resin. By this method, a lining layer having a uniform thickness is formed without generating clogging.

摘要： PURPOSE:To continuously perform a series of works, by applying inner surface repairing in a supply pipe at first and, thereafter, performing repairing due to the traction of a pig while performing an air-tightness test after repairing due to a penetrated resin. CONSTITUTION:At first, a resin lining layer is formed to the inner surface of a supply pipe 2 branched from a conduit 1 to perform a first inner surface repairing process. Next, pigs 6, 7 are introduced into the conduit 1 by the traction of a traction cable 8 to fill the conduit 1 with a primer C and a filling resin D to perform a second predetermined repairing process. At the time of this second process, because the resin D is penetrated into the branched mouth part of the supply pipe 2 to close the same, by the monitoring of a self-recording type manometer 92, it can be judged whether the supply pipe 2 is perfectly repaired. By this method, continuous repairing work is achieved.

摘要： PURPOSE: To perform secure repair without consuming resin uselessly by applying a flexible covering body for enlarging a part of a dragging wire to large diameter to the external periphery of the dragging wire in a specified range in the front side of a pig.
CONSTITUTION: Pigs 2, 3 inserted into an existing pipe 1 through an inserting pipe are drawn by the operation of the dragging wire 4. In this stage, resin C having low viscosity charged to the front side of the front pig 2 diffuses to the inside of the pipe 1 and into dusts incorporated in the space of a pipe joint 13 to improve the lubricity of the internal periphery of the pipe 1 and makes movement of resin D to be filled in the joint and the movement of a hind pig 3 easier. Furthermore, since a cylindrical body 14 is provided to the external periphery of the dragging wire 4 at the front side of the pig 3 in the stage for drawing the pigs 2, 3, the length in the inside of the pipe 1 occupied by the resin D is increased and the viscous resistance is increased and the resin pressure is also increased. Moreover, the time for filling the resin to the joint part is prolonged. Therefore, the filling time to the joint part is prolonged and the repair is performed securely with less consumption of resin.

摘要翻译：目的：通过在猪的正面的特定范围内施加用于将拖曳线的一部分的大直径放大到拖曳线的外围的柔性覆盖体，无需消耗树脂来进行安全的修复。构成：通过插入管插入现有管1中的猪2,3被牵引线4的操作拉出。在此阶段，向前猪2的前侧充填的具有低粘度的树脂C扩散到内部并且形成在管接头13的空间中的灰尘，以提高管1的内周的润滑性，并使待填充在接头中的树脂D的移动更容易。此外，由于在用于抽取猪2,3的阶段中，在猪3的前侧的牵引线4的外周设置圆筒体14，所以管1的内部长度由树脂占据 D增加，粘性阻力增加，树脂压力也增加。此外，延长了将树脂填充到接合部的时间。因此，延长接合部的充填时间，并且以更少的树脂消耗可靠地进行修理。

摘要： PURPOSE:To rapidly and easily perform the taking-out of a pig and a residual resin, by connecting and attaching a front side pig to a traction cable so as to be capable of fixing and freeing the same, and freeing said pig when taking out the same from a pipe to wind up the traction cable. CONSTITUTION:A traction cable 4 is pierced through a front side pig 2 so as to be capable of moving said pig 2 forwardly anc backwardly while said pig 2 is connected and attached to the traction cable 4 through clamp collars 28, 29 so as to be capable of fixing and freeing the same. When pigs 2, 3 are taken out from a pipe 1, the front side pig 2 is brought to a free state and the traction cable 4 is wound up to draw out the rear side replacement pig 3. By this method the taking out of the pigs and a residual resin are rapidly achieved.

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 apply resin lining to the inner surface of a pipe having a predetermined length by a low positive pressure air stream, by setting the speed of an air stream so that the flowing speed of a resin flowing in the pipe by the air stream is set to a predetermined speed or more. CONSTITUTION:As the resin A of a lining agent, one high in a non-drooping property is used. When the resin A is blown into a pipe 1 by the air stream blown from a blower 6, said air stream is set so that the speed thereof is regulated so as to impart a flowing speed to the resin A at a certain speed or more and the pressure thereof is adjusted to low positive one of about 0.6kg/ cm or less. By this method, a resin lining film is formed to the inner surface of the pipe in a uniform thickness.

摘要： PURPOSE:To discharge a penetrated resin by utilizing an air bomb, by connecting the control cock communicated with the air bomb is connected to a meter connection part and sending air into a branched pipeline under pressure while reading a meter. CONSTITUTION:The integration meter 28 provided to the terminal of a branched pipe 40 is detached from the branched pipe 40 and the hose 26 of an air bomb 21 is connected to the terminal of said branched pipe 40. Herein, the cock of the bomb 21 is opened and compressed air is introduced into the supply pipe under pressure. Whereupon, the resin penetrated into the mouth part of the branched pipe 40 is pushed back into an existing pipe but the supply of air is lasted for a predetermined time. By this method, the discharge of the penetrated resin is performed by the air bomb.

摘要： PURPOSE:To secure replacement action and to perform the certain repairing of a pipe joint part, by parallelly providing a resin filling groove and a resin replacing groove in a phase shifted state and mounting a member for preventing groove deformation to the replacing groove. CONSTITUTION:Resin introducing grooves 17 and resin replacing grooves 18 are alternately provided to the left and right peripheral wall positions of a pig 3 in parallel in a phase shifted state and a shape holding member, which is made of a metal or hard synthetic resin having a channel shaped cross-sectional area and has large notches 43a formed at both corners thereof, is formed in the replacing groove 18. By this structure, no influence is exerted on the replacing groove even if filling pressure is applied to the resin filling groove and the expansion of the groove is generated while the opening width of the replacing groove is held to a predetermined one and the repairing of a pipe joint part is made accurate.
