摘要： PROBLEM TO BE SOLVED: To provide an inexpensive folding structure of an excavator capable of holding a drilling blade in a horizontally extended state upon drilling and folding it when pulled up. SOLUTION: This folding structure of an excavator 10 used for a foundation pile construction by simultaneous burying method comprises the drilling blade 24 and a stirring blade 28 provided on a rotating shaft 26 to be rotatable about a horizontal shaft 38, and a cutout part 44 for suppressing their rotation and holding the drilling blade 24 and the stirring blade 28 in the extended state. The rotating shaft 26 comprises a locking member 50 provided to be engageable with and disengageable from the cutout part 44 and a jack 46 for moving the locking member 50. The rotation of the drilling blade 24 and the stirring blade 28 is suppressed by the engagement of the locking member 50 with the cutout part 44 by the jack 46, and the engagement of the locking part 50 with the cutout part 44 is released, whereby the drilling blade 24 and the stirring blade 28 are turned and folded smaller than the inside diameter of a tubular member 16 to be buried.

摘要： PROBLEM TO BE SOLVED: To improve demolition efficiency. SOLUTION: An in-tunnel track 10 is constructed of a plurality of crossties 12 and a plurality of rails 14. In demolition and removal of the track 10, the track 10 is divided into track blocks 18 each having a plurality of crossties 12 connected by the rail 14. When the track 10 is divided into track blocks 18a-18n, the track block 18a located on the farthest position side from a tunnel entrance is removed first. In this removal, the track block 18a located on the farthest position side from the tunnel entrance is moved upward and then shifted toward the tunnel entrance side to be placed on a rail of another tack block 18b adjacent to the track block 18a, and the placed track block 18a is towed and moved along the rail 14. In this way, the divided track blocks 18a-18n are individually conveyed out sequentially to the outside of the tunnel.

摘要： PROBLEM TO BE SOLVED: To uniformize the dehydration ratio of dehydrated cake. SOLUTION: A vibration exciter 30 for applying a prescribed vibration to the dehydrated cake is provided on a filter plate 10. The vibration exciter 30 is provided with a vibration exciting body 30a, in which a steel-made ball rotating at a high speed by compressed air is incorporated, an air supply pipe 30b for supplying the compressed air to the vibration exciting body 30a and an air discharge pipe 30c for the compressed air supplied to the vibration exciting body 30a. The vibration exciter 30 is used by 5 sets each having the same constitution on one filter plate 10 and three sets are arranged at an equal interval on the upper side from the center of the filter plate 10 and the remaining two sets are arranged on the lower side from the center of the filter plate 10.

摘要： PROBLEM TO BE SOLVED: To provide a brake structure and a brake method to provide high- reliable brake capacity through simple constitution and reduce the occurrence of malfunction and a delay in operation. SOLUTION: A brake structure is served to stop a vehicle running along an installed track 10 comprises a brake rail 11 extended and laid in parallel to the track 12; a wedge device 13 arranged at a vehicle 12 and nipping the brake rail 11; and a governor device 14 to operate the wedge device 13 to detect the speed of the vehicle 12. The vehicle 12 is stopped by a friction force when the brake rail 11 is nipped by the wedge device 13 from both sides.

摘要： PURPOSE:To perform the laying work of piping in tunnel work rapidly and safely. CONSTITUTION:A laying device 10 is formed of a portal frame 14 traveling mainly in the axial direction of a tunnel, a hoisting device 16 slided horizontally in the transverse direction of the tunnel, along the upper frame 15 of the portal frame 14, and a pipe stocker 17 suspended from the hoisting device 16. Plural pipes 28, 29 for mud feed/discharge piping are accommodated in the pipe stocker 17 and moved close to a laying position by the hoisting devcie 16. The respective pipes 28, 29 are successively taken out of the pipe stocker 17 moved close to the laying position for laying.

摘要： PROBLEM TO BE SOLVED: To provide the improving method of secondary process soil and a muddy water process facility which easily improve the water content and corn index of secondary process soil produced in a muddy water construction method to effectively utilize the secondary process soil as a filling material. SOLUTION: A muddy water process facility is composed of a primary process plant 20 for separating a sand component from a discharged muddy water accompanied with an excavated sediment; secondary process plants 21, 22, 23, 24, 25 for separating a clay component and a silt component from a surplus discharged muddy water after the primary process excepting the circulatingly reused muddy water; third process plant 26 for requlatingly processing a surplus water separated in the secondary process plants 21, 22, 23, 24, 25; and sand component charging plants 27, 30, 38 which stores the muddy water containing the sand component separated in the primary process plant 20 and supply-charges the sand component into the secondary process plants 21, 22, 23, 24, 25. There the sand component is charged from the sand component charging plant 27, 30, 38 into the surplus discharged muddy water to reduce a water content of the secondary process soil after a dewatering process and to increase its corn index.

摘要： PURPOSE:To reduce a cycle time by smoothly braking even a capsule having heavy weight and a wide range of approach speeds through a relatively simple mechanism and at a relatively short distance, and enabling the capsule to be transferred to the next process. CONSTITUTION:A capsule deceleration device such as a torque converter 4 and a drive device such as a motor 5 are connected via a reducer 3 to rubber tiers 1A and 1B rotatably supported and so laid as to be capable of being pressed to the side of a capsule C. Also, the tires 1A and 1B are kept rotating at a speed less than capsule approach speed on the operation of the motor 5. When the capsule C approaches, the speed of the tires 1A and 1B increases due to a frictional force, and the torque converter 4 at the side of the tiers 1A and 1B gives a slip relative to the drive side, thereby absorbing an excess of torque. As a result, the capsule C is decelerated and braked.
