摘要： PURPOSE:To perform excavation works effectively by providing possibility of increasing the excavation efficiency and covering work efficiency. CONSTITUTION:A plurality of cylinders 11, 12, 13, 14 are furnished and they one another connected rings 23,'24, 25, 26 consisting of an outer steel shell 21 and inner steel shell 22 are connected and a cutter 31 having a rotary shaft parallel with the excavating direction is mounted in these cylinders 11, 12, 13, 14. Two screw cutters 41, 51 which have guide shafts 42, 52 intersecting the excavating direction and whose blade diameter varies convex or concave in the rotary shaft direction are mounted in the rings 23, 24, 25, 26. One-side ends of these screw cutters 41, 51 are supported rotatably by the cylinders 11, 12, 13, 14, while the other ends are borne rotatably by bearings 67, 68 in the middle parts of the rings.

摘要： PROBLEM TO BE SOLVED: To improve water sealing performance, and to prevent leakage of grout by differencing the length of one end part and the length of the other end part running in the peripheral direction of an elastic water sealable annular plate-like seal material in a seal installed in the joining part between a cylindrical leg and a steel pipe line inserted into the leg. SOLUTION: A brush type seal 11 installed in the joining part between a cylindrical leg 5 and a steel pipe pile 6 inserted into the leg 5, is formed as a structure by combining spring steel, a wire brush and a stainless steel wire net, and is composed of a cylindrical upper member running along the inner peripheral surface of the leg 5 and an almost funnel-shaped lower member wound along the peripheral surface of the steel pipe pile 6 by extending downward from the lower end of this upper member. Here, the length of one end part and the length of the other end part running in the peripheral direction of a seal material are made different. Thus, even if dislocation is caused between the steel pipe pile 6 and the leg 5, a seal can instantly cope with it by resiliency of the brush type seal 11 to improve water sealing performance in the joining part as well as to prevent leakage of grout 9 injected into the joining part.

摘要： PURPOSE:To facilitate exchange work of a cutter bit, to lighten a burden applied on a worker, to improve safety and working performance of digging work and to exchange the cutter bit at proper time in accordance with an abrasion state of the cutter bit. CONSTITUTION:A fixed cutter bit 15 is fixed on a cutter head 12 which is free to drive to rotate, and a cutter bit 31 for exchange is installed free to appear and disappear adjacent to this fixed cutter bit 15. When the fixed cutter bit is abrased and its diggingcapacity is lowered, the cutter bit 31 is projected forward in the digging direction rather than the fixed cutter bit 15 by an actuation control mechanism 32, and digging work is carried out by this cutter bit 31 for exchange.

摘要： PURPOSE:To reduce a planar occupied space and improve the utilization efficiency of the ground by providing a vehicle storage section floated in a pool-like water tank and having a ballast tank and storage floors of vehicles in multiple stages and multiple lines and a water feed/discharge device adjusting the water level in the water tank. CONSTITUTION:The water in a water tank 2 is discharged by a water feed/ discharge pump 6 so that the uppermost storage floor 8 is set to the same level as a sidetrack 1. The water in a ballast tank 10 is fed or discharged by a ballast pump 12 in response to the storage quantity of vehicles to be kept at the preset horizontal surface and height. When vehicles are completely stored on the uppermost storage floor 8, water is fed by the pump 6, and water is fed into the ballast tank 10 by the ballast pump 12 so that the next lower storage floor 8 is set to the same level as the sidetrack 1. Vehicles are stored in individual storage floors 8 in sequence. The ground can be effectively utilized.

摘要： PURPOSE:To turn a shield excavator without applying excessive load and displacement to the ground by using a control system automatically judging the quality of the turning radius in consideration of the soil property. CONSTITUTION:When a shield excavator is turned for an excavation, the turning radius R and the turning center C are inputted to a control device 14 via an input device 16. When the turning radius R set by an operator is judged satisfactory by the control device, a shield jack 9 is driven and controlled by a shield sequencer 18 for an excavation along a circular arc specified by this turning radius R. When it is displayed on a display 17 that the set turning radius R is inadequate, the operator cancels the previous turning radius and sets a new turning radius. When it is judged satisfactory, the shield jack 9 is driven and controlled for an excavation along the circular arc specified by the new turning radius.

摘要： PURPOSE:To raise the efficiency of excavation by a method in which cutter faces are alternately attached in two stages to the front and back sides of each tip of drive shafts with an arrangement of partially lapped tip locus and turned synchronously in a noninterferential rotation phase in the opposite directions. CONSTITUTION:Cutter heads 15a and 15b consist of a front stage cutter face 15a and a back stage cutter face 15b which are attached to the tips of each drive shaft 13 projected from the front of a partition wall 12. Each of the faces 15a and 15b has bits 18a and 18b and both sides are shaped into a recessed circular arc form and widened toward the tip. The cutter faces 15a and 15b are set in two front and back stages with a mutually crossed arrangement, and the opening rate of them is greatly reduced. The holding property or sheathing performance of the facing can thus be enhanced.

摘要： PURPOSE:To continuously and accurately measure the volume of discharged earth by finding the cross-sectonal area of earth and sand on a belt conveyor by an ultrasonic measuring sensor, and multiplying it by the conveying speed of the belt conveyor and measuring the flow rate of the earth and sand continuously. CONSTITUTION:Plural ultrasonic distance measuring sensors 15 are installed over the belt conveyor 13 and measure the distance between the surface of the earth and sand 12 on the belt conveyor 13 and the sensors 15 continuously to find the thickness of the earth and sand 2. Further, a side wall 17 is installed at the fixed part of the belt conveyor 13 and the cross-sectional shape of the belt conveyor 13 is determined, so that the cross-sectional area of the earth and sand 12 is calculated. For the purpose, the conveying speed of the belt conveyor 13 is found by a tachometer generator 18 and multiplied by the cross- sectional area of the earth and sand to find the flow rate of the discharged earth and sand continuously.
