摘要： PROBLEM TO BE SOLVED: To drive a hollow drain material surely without depending upon a hard layer. SOLUTION: A drilling unit 10 consisting of an outer tube assembly 13 and an inner tube assembly 14 having cutters 11, 12 at front ends respectively is supported to a rotary unit 4 for an excavator 1, the drilling unit 10 is turned and moved in the axial direction by operating the rotary unit 4 and a slider 3, and a ground 5 is excavated by the cutters 11, 12. The ground is drilled in specified depth, an overshot 7 is inserted into the outer tube assembly 13, the inner tube assembly 14 is extracted while a latch mechanism 15 for the inner tube assembly 14 is separated from the outer tube assembly 13, and the pipy drain material 16 is inserted into the outer tube assembly 13 in place of the inner tube assembly 14. The outer tube assembly 13 is pulled out while the upper end of the drain material 16 is held down by a weight 20, and the drain material 16 is left in the ground 5.

摘要： PROBLEM TO BE SOLVED: To provide a dehydrating device for sludge free from plastic deformation of a filter plate caused by pressure difference with a simple structure. SOLUTION: In the pressure dehydration carried out by pressing one end side with a pressing means such as a hydraulic jack and forcibly feeding the sludge with a forcibly feeding sludge pump or the like from another end side, the plastic deformation of filter plates 1, 2 caused by the pressure difference between a filter press part for forcibly dehydrating the high concentration sludge and a filter press part for forcibly dehydrating low concentration sludge is prevented by the repulsive force of an intermediate reinforcing material 6, which is generated by butting and elastically deforming the intermediate reinforcing material 6 composed of an elastic body provided at the same place of both surfaces of a 1st filter plate and a 2nd filter plate 2 or at one surface of the same side of one of the 1st filter plate and the 2nd filter plate.

摘要： PROBLEM TO BE SOLVED: To increase the treatment quantity of sludge as compared with the present dehydration treatment apparatus by further enhancing dehydration work efficiency. SOLUTION: In the control system of the primary dehydration process in a filter press type two-stage pressing dehydration treatment apparatus, it is detected that the filter chamber formed between filter frames comprising an elastic material has a predetermined width and the movement of a filter plate is stopped when the detection result shows the predetermined width.

摘要： PROBLEM TO BE SOLVED: To place the pneumatically force-fed improved sediment stably and efficiently in the water. SOLUTION: The improved sediment 2 pneumatically force-fed by a transportation pipe 1 is guided into a cyclone 4 together with air 3, and the improved sediment 2 is separated from the air 3. When the boundary face of the separated improved sediment 2 rises to the upper limit position in the cyclone 4 from a placing pipe 5, an exhaust valve 22 in an exhaust pipe 19 is opened based on the signal from an upper limit sensor 31A, the air pressure in the cyclone 4 is increased, the improved sediment 2 is pushed into the placing pipe 5 by this air pressure, a check valve 30 at the tip of the placing pipe 5 is opened by this pushing pressure, and the improved sediment 2 is discharged to a placing object. When the boundary face of the improved sediment 2 in the placing pipe 5 is lowered to the lower limit position, the exhaust valve 22 is opened based on the signal from a lower limit sensor 31B. When these actions are repeated, the improved sediment 2 separated by the cyclone 4 is intermittently discharged from the placing pipe 5.

摘要： PROBLEM TO BE SOLVED: To provide a dehydration means to efficiently obtain dehydrated cake of a low moisture content ratio, is simple in construction, is highly durable and is inexpensive. SOLUTION: Supporting arms 14 of movable stoppers 4 are loosely fitted to guide parts 71 disposed in the front and rear surface parts of a first filter plate 1 nearer the outer periphery than filter frames 11, 12. These supporting arms 14 are hooked and supported to parallel rods 15... moving near to and apart from a filter press body A from both right and left sides to suppress the entire load of the movable stoppers 4 so as to act small as a loading force on frame opening devices (known structures consisting of chains and hooking parts disposed apart prescribed intervals from the chains) B. The filter plate is slid and guided without meshing with the parallel rods 15 by the clearances 14b of recessed parts 14a for hooking disposed at the supporting arms 14. These clearances 14b accelerate the play of the filter plate by the initial track error of the frame opening devices B.
