摘要：【課題】従来と異なる方法によって管を持上げる。【解決手段】さや管P’の内面間にベース部材10を架け渡し、そのベース部材の中程に新管Pの上下径方向の押し当て手段30を設け、その押し当て手段により、新管の上下径方向cのさや管の天井に吊下げベース20を押し当て、その吊下げベースから新管の下端に線状体40を導いて固定する。線状体に介設された治具50で線状体を縮長させて新管を持上げる。このとき、線状体は新管の径方向cの両側に位置し、その線状体に対して新管は線対称となって持上げられ、不要な外力が加わらない限り、真っ直ぐ持上げられる。吊下げベースは押し当てによってさや管内面に固定され、ヒューム管のように、その内面が平らな凹凸がない面であっても、その吊下げベースを容易に固定できる。さや管内に、ベース部材、吊下げベース、押し当て手段を十分納まる大きさとすることができ、さや管内に広い作業空間を確保する必要もない。【選択図】図2

摘要： PROBLEM TO BE SOLVED: To provide a lock ring which forms a stabler joint structure.SOLUTION: There is provided a lock ring 1 for pipe joint such that: a ring part 2 is tapered to be larger in diameter on the side of an opening of a socket 11, and also divided at one place to be elastically expandable in diameter; the ring part 2 is provided with a plurality of leg projections 3 raised in outer-diameter directions; when the ring part 2 is put in a lock ring groove 13, a large-diameter end of the ring part 2 and the leg projections 3 restrict movement in a pipe axial direction; when pulling-out force is applied on an insertion hole 12 from the socket 11, an anti-loosening projection 16 at an outer periphery of the insertion hole 12 abuts on a small-diameter end of the ring part 2 to stop the insertion hole 12 from coming out of the socket 11. A leg projection which faces the division part of the ring part 2 among the leg projections 3 is formed by bending both ends at an angle of inclination to a peripheral direction, and an end face of the leg projection 3 is in level with a small diameter-side end face of the ring part 2 while connecting with a base part.

摘要： PROBLEM TO BE SOLVED: To efficiently lay a pipeline with water stopped penetrating a levee body with non-cut-and-cover. SOLUTION: A injection nozzle 21 is screwed vertically from the levee crown 11 to a levee body 1, cement slurry S mixed with a hardening accelerator is jetted from the tip and exchanged to form a vertical columnar body and this procedure is repeated, an impervious wall main body 3 having required height and width is formed, an excavation machine 7 having a diameter slightly larger than a drive pipe is attached to the tip of a drive pipe from a shaft 4, this drive pipe is pushed horizontally into the levee body and made longer by jointing additional pipes, when it reaches a scheduled drive pipe 5X intersecting with the main body 3 of impervious wall in the shaft 4, a plurality of ring-shaped impervious bags are folded housed in freely expandable manner, at this time, an impervious drive pipe 6 with a grout inlet opened is connected, the ring-shaped impervious bag is covered, drive is continued while the ingress of sediment is blocked, a pipeline penetrating through the levee body 1 is formed, the impervious bag is expanded to the outer peripheral side, gap C between a penetration hole 31 of the main body 3 of impervious wall and the impervious drive pipe is partitioned, blocked and closed tightly, grout is injected into the gap and filled, and a pipeline having high water stopping ability is laid by non-cut-and-cover.

摘要： PROBLEM TO BE SOLVED: To ensure water barrier function so as to eliminate anxiety about water leakage and to execute work safely in the case of laying a pipeline piercing a dam body by non-open-cutting. SOLUTION: Cement slurry is injected inside from the upper part of a dam body 1 to construct a water barrier wall body 3 for cutting off a predetermined pipeline. Propulsion pipes 5A, 5B,... are horizontally pushed into the dam body 1 from a shaft 4 while cutting, and a water barrier propulsion pipe 6 provided with two elastic water barrier rings 61A, 61B and a grout filling port 62 between both members is interposed in a predetermined position intersecting the water barrier wall body 3. After forming a predetermined pipeline by extending normal propulsion pipes, an actuating means 7 is started to make two elastic water barrier rings bulge outward to form a closed space partially partitioning an annular clearance C between the outer peripheral surface and a cut face at the time of propulsion. Group is filled in the space to replace it with a grout filled layer M, thus providing water barrier function.

摘要： PROBLEM TO BE SOLVED: To easily specify the positions where a turbid substance is likely to deposit in a whole area where tap water is supplied, and to easily determine the timing of washing of piping. SOLUTION: The whole area is divided into a plurality of meshes 2. Speed of increase of the turbid substance in each mesh is estimated by performing multi-regression calculation employing the speed of increase of the deposit amount of the turbid substance 18 as objective variables, and employing the number of dead ends 6 per unit length of the piping 3, a ratio of the piping length of a mortar lining piping laid before the year 1990 to the total extending length of the piping, and three of coefficient of discharge as explanatory variables. A result of an analysis for each mesh is two-dimensionally displayed on a display screen 1, so that the deposit condition of the turbid substance for the whole area can be grasped visually. Further, as the timing of washing the piping is calculated by dividing an acceptable deposit amount of the turbid substance by the speed of increase and is displayed two-dimensionally, distribution of the timing of washing the piping in the area can be easily determined.
