    • A sewage by-pass drainage system for sewage pipe works comprises a submerge pump provided in a first manhole, a sewage pipe between a second manhole and a third manhole located at a downstream side of the first manhole being taken as a working zone, an upstream side stop plug being provided at an outflow side of a sewage pipe between the first manhole and the second manhole, and a downstream side stop plug being provided at an inflow side of a sewage pipe opening to the third manhole, a suction pipe of a suction drainage apparatus provided on the ground being projected into an upstream side of the upstream side stop plug, a discharge pipe of the suction drainage apparatus being projected into a downstream side of the downstream side stop plug, and a discharge pipe of the submerge pump being arranged to the downstream side of the downstream side stop plug. By this, a sewage or the like can be drained even from the deeply buried sewage pipe so that an odor may not leak above the ground.

    • The purpose of this invention is to provide an actuator for valve driving without enlarging its size, without increasing the cost, and without reducing the pressure receiving area of the pistons. In order to achieve the purpose, the present invention comprises the left and right side cylinders supporting each of the piston to slide freely towards the center of the piston rod, and the first passageway that communicates the left side cylinder room of the left side cylinder with the left side cylinder room of the right side cylinder where both cylinders are separated by the pistons, and the second passageway that communicates the right side cylinder room of the left side cylinder with the right side cylinder room of the right side cylinder where both cylinders are separated by the pistons, and the converter that converts the piston rod's reciprocating motion towards the center of the rod into the rotating motion of the valve driving shaft, and thereby being characterized by having the first and second passageways in or around the supporting members of the left and right side cylinders.
    • 本发明的目的是提供一种用于阀驱动的致动器,而不增大其尺寸,而不增加成本,并且不减小活塞的受压面积。 为了达到这个目的,本发明包括左右两侧气缸,其支撑活塞的每一个自由地向活塞杆的中心滑动;第一通道,其将左侧气缸的左侧气缸室与 右侧缸体的左侧缸室,其中两个气缸由活塞分隔;以及第二通道,其将左侧气缸的右侧气缸室与右侧气缸的右侧气缸室连通,其中两个气缸均为 由活塞分离的转换器,以及将活塞杆往复运动朝向杆的中心转换为阀驱动轴的旋转运动的转换器,由此具有在第一和第二通道中的第一和第二通道内的支撑构件 左右气瓶。

    • A sewage by-pass discharging apparatus for sewage pipe works comprises an upstream side stop cock disposed at an upstream side of a sewage pipe laid in a working area, a downstream side stop cock disposed at a downstream side of the sewage pipe laid in the working area, a member for discharging the sewage accumulated at an upstream side from the upstream side stop cock to a downstream side from the downstream sides stop cock by bypassing the sewage pipe, a drain pipe connected to the sewage pipe laid in the working area, a drain pit connected to the drain pipe, a stop cock for preventing the sewage from flowing from the drain pit into the drain pipe, and a unit discharging the sewage reserved in the drain pit to downstream side from the downstream side stop cock. According to this structure, the working to the sewage pipe can be performed while the sewage system is maintained in a state of being utilized as usual by the residents of the respective homes.
