摘要： PURPOSE: To make it possible to form easily a large scale underground space. CONSTITUTION: A group of shield tunnels selected alternately from adjacent shield tunnels 10 in a connected state, are specified as preceding tunnels 10a, which are excavated by excavating under the development of a back-filled setting body having a specified thickness around a segment 15 assembled in the rear of a shield machine. A group of left over shield tunnels are excavated as a following shielded tunnel 10, thereby forming a part of the back-filled setting body 16. Each shielded tunnel segment is properly reinforced with a support member 19 while the segments located at each connection part 20 are removed and the back-filled setting body 16 is removed, thereby communicating each adjacent shielded tunnel. Each connection segment 21 is set up between the segments of the adjacent shield tunnels, thereby forming a crust 13 which covers the ground 12. Then, the ground inside the crust is excavated.

摘要： PURPOSE: To make a slab base material easy to carry into a tunnel and easy to erect when a partition wall using the slab base material as a skeleton is formed in a tunnel lining wall. CONSTITUTION: Projections 20 having fitting faces 21a are formed at the suspension positions of a slab base material 30 on both side walls of a primary lining wall 2, and steel plates 50 are buried in their inner faces 21b. Connecting faces 36 to be mated with the fitting faces 21a and fitting plates 35 forming the mount faces 37 to be mounted on the steel plates 50 are fixed at both ends of a base material main body 32 made of multiple H-steels 31 to form the slab base material 30. The connecting faces 36 of the fitting plates 35 are mated with the fitting faces 21 of the projections 20, the mount faces 37 are mounted on the steel plates 50, and the fitting plates 35 are fixed to insert metals 22 buried in the projections 20 by bolts.

CONSTITUTION: A projecting wall portion 23 whose upper surface serves as a bearing face 22 is formed on one of the opposite side wall portions of a lining wall and a locking wall portion 32 is formed on the other side wall, and a slab 51 constituting a partition wall between the wall portions 23, 32 is placed with one side placed on the bearing face 22 of the projecting wall portion 23 and the other side locked into the locking wall portion 32. A locking portion whose cross section takes approximately the same form as the cross section of a locking groove formed in the locking wall portion 32 is formed on the other side of the slab 51, and the locking portion is locked into the locking groove.

摘要： PURPOSE:To prevent a safety valve from blowing up due to a columnar resonance phenomenon under pressure less than specified one by specifying the inlet diameter and length of a nozzle neck in the nozzle neck for a safety valve, which is installed normal to a plant pipeline in a power plant and the like, and has the safety valve installed at its tip end. CONSTITUTION:In a device where a nozzle neck provided with a safety valve 4 at its tip end is connected perpendicularly to a mother pipeline (plant pipeline) 1, and its safety is assured by letting the safety valve 4 be automatically released when pressure within a pipline exceeds a specified value, a cut 3 of 45 deg. is applied to the whole circumference of an inlet for a safety valve nozzle neck 2. The cut 3 is formed in such a way that a nozzle neck inlet diameter do satisfies the relation of do=(1.05 to 1.4)d with respect to a nozzle neck inner diameter d. Besides, the amount of cutting and the length of the nozzle neck are so determined that the natural frequency fs of the safety valve, cavity noise frequency fc, and columnar resonance frequency fn do not coincide with one another so as to be sufficiently separated from one another. By this constitution, columnar resonance can effectively be prevented.

摘要： PURPOSE:To provide a priming apparatus for use in a pump wherein effective discharge of a reserve pump is accelerated by connecting suction filters or the lower parts of a normal and the reserve pumps by a uniform pressure pipe and also connecting the uniform pressure pump to a common discharge pipe by means of a valve. CONSTITUTION:Check valves 5-1, 6-1 and stop valves 12, 13 are fully opened, and a stop valve 15 is fully closed during operation a normal pump 2-1. A suction pipe of a reserve pump 2-2 is filled with a liquid in a tank 1 by the vacuum action of the normal pump and by means of a uniform pressure pipe 11. If the normal pump develops trouble, the effective discharge is immediately obtained by running the reserve pump 2-2. At repairs for the normal pump 2-1, the stop valve 13 is closed. Priming to a filter 3-1 at the normal pump side is carried out, making use of the discharge liquid from the reserve pump 2-2 which is fed through a feed pipe 14 and the uniform pressure pipe 11 by opening the stop valve 15.

摘要： PURPOSE:To reduce the increase of opening/closing torque for a ball valve and prevent the malfunction by providing a means of reducing the increase of the valve opening/closing torque as a result of particles contained in conductive fluid passing therethrough precipitated and fixed onto seats. CONSTITUTION:A body 1 which constitutes a floating type of ball valve 10 holds a ball 3 inside via a drive shaft 2, and at the inner edges on the entrance side 4 and on the exit side 5 teflon seats 6 in contact with the outer periphery of the ball 3 are formed. In the body 1, cleaning liquid entrances 8 and a cleaning liquid exit 9 each of which penetrates through a jacket 7 from the outside face are provided. Fluid with the same nature as conductive fluid passing through the ball valve 10 is supplied from the cleaning liquid entrances 8 to the jacket 7 and drained from the cleaning liquid exit 9 for all time circulation. In this way, there is no precipitation of particles included in the conductive fluid. the increase of valve opening/closing torque is prohibited and the malfunction is prevented.
