摘要： PROBLEM TO BE SOLVED: To make a removing unit smoothly movable even if a difference in level exists on the inner surface of a pipe. SOLUTION: In the cleaning device, the removing unit 1 is constituted by providing a striking member 8 supported so as to be freely shaken around an oscillation axis Y, which is eccentric from rotary axis X along the longitudinal direction of a pipe, in the peripheral direction of the pipe and a drive part 9 for rotationally driving a rotary member 7 to the rotary member 7 rotated around the rotary axis X. This removing unit 1 is moved through the pipe while striking the inner surface of the pipe with the striking member by rotationally driving the rotary member to remove matter having adhered to the inner surface of the pipe. A front guide member 3, which is equipped with a projected curved surface 2 projected toward the front in the moving direction within the pipe, is provided to the front in the moving direction within the pipe for the adhered matter removing work of the removing unit.

摘要： PROBLEM TO BE SOLVED: To provide a flushing method for sewer pipes avoiding problems in working safety and improving working efficiency.
SOLUTION: A flow changing ball 7 is put in a sewer pipe 1, filth remaining in or sticking to the inside of the sewer pipe is removed by forcedly moving the ball 7 in the direction opposite to the outflow direction of the sewer. The flushing method is constituted of a first process in which the ball is arranged on the pipe bottom 5a in the sewer pipe 1 and is forcedly moved and a second process in which the flow changing ball 7 is arranged in the upper wall 5b of the sewer pipe 1 after completion of the first process and is forcedly moved a plurality of times.

摘要： PROBLEM TO BE SOLVED: To overcome problems such that conventional expensive equipment has a system incapable of being installed and brings about many worries concerning the safety of a worker, inconvenience to local residents, an obstruction to traffic and the like. SOLUTION: Suspended matter and a sediment, flowing into a manhole pit, are cleaned by generating a swirling flow through the use of energy of an inflow of waste water. Thus, since the swirling flow is generated at each of the inflows of the waste water, the cause of a malodor can be eliminated; and a manhole can be easily maintained by virtue of the absence of danger from the opening of a manhole lid and a hindrance to road traffic, so that the various problems can be overcome. Additionally, this system can be installed in all the manholes.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for reclaiming existing piping, which uniformalizes the thickness of a steel lining formed on an inner surface of a deteriorated pipe laid underground, facilitates the execution of work, and allows the work to be executed by using relatively small construction machinery and implements.
SOLUTION: The construction method for reclaiming the existing piping is characterized as follows: after an inner peripheral surface of the deteriorated piping laid underground is scraped down, standard-size plastic pipes, whose diameter is slightly smaller than an inside diameter of the piping, are inserted and advanced in the piping while being connected sequentially to annular recessed grooves formed on outer peripheries of butt ends of the leading and following standard-size plastic pipes via joints having an outside diameter approximately equal to that of the standard-size plastic pipe, so as to form the continuous steel lining having a prescribed length; and a filler is infilled into a gap between an outer surface of the steel lining and the inner surface of the deteriorated piping so as to integrate the steel lining with the piping.

摘要： PROBLEM TO BE SOLVED: To provide a high-presser cleaning car which does require exchanging of components in a pump and assembling of a high-pressure water generation changeover system in the pump itself and is constituted in such a manner that the standard high-pressure water pump can be changed over to a high pressure and an ultrahigh-pressure in the state of maintaining the output of the driving source of the car body. SOLUTION: This high-pressure cleaning car is mounted, on a chassis frame, with a cleaning water housing tank 3, the pump 4 which forcibly feeds the cleaning water in the tank 3 as the high-pressure water, hoses 5 (high-pressure side hose 5a and ultrahigh-pressure side hose 5b) which introduce the high- pressure water to a section to be cleaned and reels 6a and 6b which take up or deliver the high-pressure side hose 5a and the ultrahigh-pressure side hose 5b. A drive shaft 7 of the pump 4 and a side PTO 8 of a car body are connected by means of a propeller shaft 9. A clutch 11 and a speed changer 10 are interposed to the propeller shaft 9. The speed changer 10 is made changeable over to the ultrahigh-pressure side and the high-pressure side.
