摘要： PURPOSE: To easily obtain a crushed material with a grain size distribution suited to use by arranging a pair of rotors each equipped with a plurality of plates in a mutually opposite direction and variably in the number of rotation, in the interior of a casing with a lower discharge port, and at the same time, arranging a screen along the lower surface of the rotors. CONSTITUTION: A pair of rotors 7 each with a plurality of plates 9 are arranged in a mutually opposite direction and variably in the number of rotation, in both upper and lower parts of a casing 2, and at the same time, a screen 8 is arranged at a specified interval along the lower surface of the rotors 7 and in such a manner that the screen can be replaced. The screen 8 has a sieve mesh which varies according to use. When using this dehydrated cake crushing device, a dehydrated cake 13 is charged into the charge port of an upper hopper 1, then drops into a crushing chamber 6, and is crushed by collision between the plates 9 of two rotors 7 which rotate reversely to each other at a high speed. After the crushing, the dehydrated cake is discharged as crushed dehydrated cake 14 from the discharge port of a lower hopper 4, after passing through the screen 8.

摘要： PURPOSE:To improve the accuracy of the mixing of construction materials and prevent the entrapment of air bubbles in such a mixture and the lowering of the efficiency of a pump for feeding the mixture by a method wherein a lapsibly hardenable material such as cement is previously dissolved into a milky liq., this liq. is mixed with surplus soil slurry and the resulting mixture is thereafter pressed and dehydrated. CONSTITUTION:To produce reformed surplus soil material, a raw liq. pump 5 and a cement milk pump 26 are operated to feed material 1 hardenable with time consisting of surplus soil slurry 3 and cement milk into a mixing tank 8 for stirring and mixing thereof. On the other hand, a hydraulic jack 32 is extended to press together fixed, intermediate and movable forming units 33, 34 and 35 into close contact and a high pressure driving pump 17 is thereafter operated to send a mixture 31 from the mixing tank 8 into a filter press 7 under high pressure. After completion of mixture filling, the driving pump 17 is stopped and the mixture in the filter press 7 is pressed and dehydrated. The mixture thus dehydrated, i.e., the reformed surplus soil material, is taken out from the filter press 7 and loaded on a cake transfer conveyor 29.

摘要： PURPOSE:To contrive the improvement of equipment capacity and crushed stone quality by disposal and an effective use of the surplus soil in a construction site produced by excavation for construction work or tunneling work. CONSTITUTION:In a method for an effective use of the surplus soil in a construction site wherein the surplus soil is mixed with cement type stabilizer, the resulting mixture is pressed and dehydrated into the form of a cake and this cake is crushed and classified for an effective use, an additive agent such as sand or an aggregate is returned to a kneading or mixing process to be added to slurry. In doing so, the dehydrating time is shortened, all the soil-treating processes are considerably improved in capacity and the hardened soil and crushed stone produced through such processes are so improved that frequency in the effective use of the surplus soil is enhanced.

摘要： PURPOSE:To provide a method for reducing and effectively using the surplus soil in a construction site produced by an excavation for construction work or tunneling work. CONSTITUTION:In a method for an effective use of the surplus soil in a construction site wherein the surplus soil is mixed with cement type stabilizer, the resulting mixture is pressed and dehydrated into the form of a cake and this cake is crushed and classified for an effective use, the filtered water produced at the stage of pressing and dehydration is returned to a process for dissolving and selecting clayey soil for reuse as an additive water. Since, by this method, the calciumcontaining alkaline filtered water discharged from a high pressure dehydrating device is used as an additive water to clayey soil in a material adjusting process, the discarding operation of the filtered water by neutralization can be reduced and the expenses arising from its discarding can be saved. Since the calcium-containing filtered water is used in dissolving and selecting the clayey soil, the hardening of the cement portion is accelerated and the crushed stone having even better quality can be produced.

摘要： PURPOSE:To prevent a flexible elastic diaphragm from getting worn, scratched, and from pinching foreign matter due to contact of the diaphragm with an inner wall of a container and an inner supporting body by providing the flexible elastic diaphragm in a force feeding device. CONSTITUTION:A flexible elastic diaphragm 7 is positioned between an outer tube 6 and an end flange 9 to provide a pressurizing chamber 13 on the upper side and a chamber to be pressurized 14 on the lower side. Since pressure by fluid is distributed evenly on the flexible elastic diaphragm 7, the diaphragm 7 is deformed without offset when it is expanded and, therefore, it is not made in contact with the outer tube 6 even if a buoyancy acts on the diaphragm 7.

摘要： PURPOSE: To facilitate the post-treatment after dehydration and the utilization of a dehydrated component by separating impurities, stone lumps and sand from sludge when dredging sludge is dehydrated and dehydrating fine granular soil under specific pressure by a filter press. CONSTITUTION: Dredging soil 41 is collected from a water channel 40 by a bucket dredging ship 1 equipped with dredging buckets 2 to be stored in a tank 3. After primary impurities 16 are separated, the solid of primary separated sludge is slurried and fine granular soil bonded to stone lumps, gravel 17 and sand 18 is washed off. After stone lumps are separated from the slurry after treatment, the slurry is subjected to secondary separation and tertiary separation to be stored in a relay slurry tank 34. Herein, the slurry is sent to a high pressure filter press 36 to be filtered under pressure of 1.9-5.9HPa. As a result, a hard slurry dehydrated cake low in water content is obtained.

摘要： PURPOSE:To disintegrate the planar reformed surplus soil materials right after being discharged from a filter press with high efficiency by a simple means to nearly prescribed sizes. CONSTITUTION:The front part of a transporting conveyor 2 extending forward from the lower part of a filter press 1 is provided with a chute 3 extending diagonally downward from the front end of this transporting conveyor 2. A main roll 5 for disintegration and auxiliary roll 6 for disintegration which are rotated by a driving device 4 and extend in a lateral direction are provided apart a spacing in a parallel state diagonally downward of this chute 3. The main roll 5 for disintegration and the auxiliary roll 6 for disintegration have many annular projecting parts 7 and annular projecting parts 8 disposed with deviation by a half pitch in the longitudinal directions of the rolls. The spacing between these annular projecting parts 7 and 8 is set smaller than the thickness of the planar improved surplus soil materials 9.
