Title: Construction method of cut-off wall for river work and temporary gate
Inventor: KUROTANI HIDEO
IPC: E02D19/04
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility of damage of flood above floor level, by forming a cut-off wall in the stream direction with steel sheet piles and forming a cut-off wall in the breadthwise direction of a river with temporary gates and connecting the cut-off wall of the steel sheet piles and the cut-off wall of the temporary gates through a cut-off rubber material. SOLUTION: A cut-off wall 2 is constituted of steel sheet piles and a cut-off wall 4 is constituted of stoplogs-gates 41-43. A cut-off wall 5 is constituted of flap gates 51, 52 and a stoplogs-gate 53, and the cut-off wall 2 and the stoplogs-gate 41 are connected through a cut-off rubber material 6. After water has been conducted into a construction section 1 by opening the stoplogs-gate 4 of the upstream side and handles are pushed up and the flap gates 51, 52 are opened by the stream. When closing them, wireropes connected to fitting metal tools are pulled by a winch or the like. At a flood or a storm, first, the door body of the stoplogs-gate 4 is removed and secondly, the door bodies of the flap gates 51, 52 are opened, to increase the section of the river and avoid the abrupt rise of water level. And hence, flood above floor level can be prevented.

IPC: G03F1/92
Filed: 1989-08-28
Abstract: PURPOSE:To simplify a tracing operation by penetrating the light shieldable ink applied within the contours of patterns and exactly stopping the penetration on the verge of the inner periphery of the contours in a tracing stage. CONSTITUTION:This method has a size placing stage for fine lines to print the contours of the patterns by the resist size colored on the liquid penetratable film of light transparent tracing paper and the tracing stage to apply the light shieldable ink within the contours of the patterns placed with the size on the tracing paper and to penetrate the ink down to the verge on the inner periphery of the patterns. Further, a copying stage to copy the patterns traced on the tracing paper onto the light transparent film is provided; in addition, the resist size is so selected that the contours of the patterns are not drawn on the light transparent film in the size placing stage for fine lines. Namely, the resist dye printed on the liquid penetratable film in the size placing stage for fine lines dams up the light shieldable ink applied in the tracing stage to prevent the ink from bleeding out of the outer periphery of the patterns to the outside. The exact tracing is easily and rapidly executed in this way without requiring a high degree of skill.
