摘要： PROBLEM TO BE SOLVED: To implement a floating prevention construction for an underground structure, which can prevent buoyancy applied to the structure and deformation of the same accompanying the buoyancy.
SOLUTION: A peripheral wall of the underground structure has bored therein a plurality of recesses and through holes communicating with the same, and an inner pipe is arranged in each recess and the through hole communicating with the same, followed by attaching a water collecting pipe to a front end of the inner pipe. Further the inner pipe is fixed to the structure via a water cutoff material and an outer pipe, and the recess is sealed with a water cutoff band, followed by setting a drain pressure adjusting device at a rear end of the inner pipe.

摘要： PROBLEM TO BE SOLVED: To enable recovery of a crushing head, to efficiently mount a water collecting pipe without being affected by the hardness of the ground, and to prevent an accident of ground subsidence. SOLUTION: An opening part of a cylindrical drawstring bag is fixed to a front end of a cylindrical outer pipe of a press-fit pipe including the outer pipe, and an inner pipe insertably arranged in the outer pipe in a manner of allowing the water collecting pipe to penetrate. A string for closing the drawstring bag by pulling the opening part of the drawstring bag is arranged outside. The inner pipe is provided with a crushing body which is provided with the crushing head and a rod. The crushing body is freely insertably arranged in the inner pipe by the intermediary of a packing for the crushing head. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：为了恢复破碎头，有效地安装集水管而不受地面硬度的影响，并防止地面沉降事故。解决方案：圆筒形束带袋的开口部分固定在包括外管的压入管的圆柱形外管的前端，以及内管可插入地布置在外管中，允许集水管渗透。通过拉动拉绳袋的开口部分来关闭拉绳袋的绳子设置在外侧。内管设有破碎体，该破碎体设有破碎头和杆。破碎体可以通过用于破碎头的包装的中间自由地插入地布置在内管中。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a structure for preventing floating of underground structure, capable of ensuring safety in stepping-up and -down, taking excess pore water pressure (buoyancy) caused by liquefaction into a manhole or culvert that is an underground structure, and attaining rapid drainage through a combination of drainage by overflow and drainage with a draining pressure adjustment device.
SOLUTION: In the underground structure 1 such as the manhole, a recessed part and a through-hole continued thereto, the through-hole connecting between the underground side and the inside of the underground structure, are linearly bored in a plurality of positions of the circumferential wall of the underground structure in the axial direction of the manhole while avoiding step positions. A water catchment pipe with an excavating head attached to its top end is disposed in the recessed part and through-hole while intruding into the ground in a predetermined length. A first tee is attached to the base part of the water catchment pipe, and a second tee having a draining pressure adjustment device is attached to the base end of the water catchment pipe of the bottom stage. The first tee is connected to a guide pipe vertically provided within the manhole and disposed with its upper end above the ground water level, and the second tee is connected to the lower end of the guide pipe.

摘要： PROBLEM TO BE SOLVED: To provide a concrete jacking pipe that can reduce frictional resistance via relatively simple work and equipment and ensures a long jacking distance. SOLUTION: The concrete jacking pipe 1 for use in construction of a sewerage pipe or an electrical pipe has a spigot 13 at one axial end 11, a collar 14 fixed at the other end 12, and injection holes 4 in given intermediate positions. Except for the spigot 13 and the injection holes 4, an outer circumference of the jacking pipe has a resin coating 5, which reduces frictional resistance to a lubricant or filler injected between the outer circumference of the jacking pipe and natural ground.

摘要： PROBLEM TO BE SOLVED: To enable the wasteless injection of a lubricant into a part with large frictional resistance by providing an integral structure for the metal sheet of an attached body and a jacking pipe made of concrete and measuring the frictional resistance of the jacking pipe in natural ground by a distortion gauge. SOLUTION: The metal sheets 1 of attached bodies 4 in which the metal sheets 1 are welded to the upper ends of anchors 2 arranged at predetermined intervals are circumferentially arranged in parallel more internally than pipe ends along the pipe axis. Then the surfaces of the metal sheets 1 are exposed to the side of the inner surface of a jacking pipe 3 and are arranged, and the lower ends of the anchors 2 of the attached bodies 4 are secured to an outer mold frame 8 by bolts 81 to form the jacking pipe 3.
