IPC: E02D5/20
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To provide the structure of a diaphragm wall, in which construction cost is reduced and the term of works is shortened. SOLUTION: In the diaphragm 1 used as the earth retaining of an underground structure, an approximately truncated-shaped bottom expanding section 2 is formed to the lower section of the diaphragm 1 at a specified space. A ditch for the diaphragm is excavated and the bottom expanding section 2 is excavated to the lower section of the excavated ditch by using an excavator, in which a bottom expander is installed at a front end, or a vertical pit containing the bottom expanding section 2 is excavated previously and the ditch is excavated so that the bottom expanding section 2 is formed as a lower section. Slime in the ditch, to which the bottom expanding section 2 is formed, is removed while a cage is disposed and the diaphragm wall is formed by placing concrete.  Since floating resistance force to ground water is increased by the bottom expanding section at that time, the wall thickness of the diaphragm can be formed thinly.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To detect an instantaneously bursting vibration quickly and sensitively through simple structure by measuring the electromotive force being induced in the coil of a fixed magnetic pole when a magnetic ball arranged on the border line of a magnet traverses an elliptical line of magnetic force developed from a planar magnet while facing each other and penetrating a fixed magnetic pole. SOLUTION: A magnetic ball 6 is mounted on the border line of planar magnets 5a, 5b in a stator 5 arranged such that the adjacent poles attract each other and a fixed magnetic pole 1 applied with a coil 2 is arranged on the center line thereof thus constituting a vibration sensor where elliptical line of magnetic force is developed from both magnets 5a, 5b while facing each other and penetrating the fixed pole 1. When the ball 6 in the sensor moves to traverse the line of magnetic force, the line of magnetic force fluctuates to induce an electromotive force in the coil 2 and the external force (vibration) caused to vibrate the ball 6 can be detected by measuring the electromotive force. Furthermore, sensitive action can be realized because the ball 6 comes into point contact with the stator 5.
