摘要： PROBLEM TO BE SOLVED: To provide an excavator capable of driving forward in the horizontal direction without drawing up an excavation rod to the ground after the ground is excavated in the longitudinal direction, capable of forming efficiently an underground continuous wall and, at the same time capable of forming an improved ground layer continued in the horizontal direction in the specific depth in the ground, and to provide a method making use thereof and a continuous wall construction method. SOLUTION: A pair of endless circuit blade continuous bodies 52A and 52B capable of traveling along the vertical direction are provided to both sides of a vertical excavation rod 46. All of them are used as an excavator main body and are capable of rising and falling, excavation is made by an auger head 50 in the lower end of the excavation rod, and the ground is scraped and raked up by a large number of blades provided to the blade continuous bodies in the vertical direction at specific intervals.

摘要： PROBLEM TO BE SOLVED: To prevent the settlement of ground on a construction site by circulating an endless chain having cutting and agitating wings projected out along the outer periphery in a direction of scratching down with a post located at the center of the circulation thereby excavating earth and placing and agitating a solidifying agent in the drilled ground. SOLUTION: A post 1 is supported in a vertical direction by a base machine 4 in a freely rising and descending manner. And an endless chain 2 having cutting and agitating wings 3 projected out along the outer periphery is tensioned and circulated between the top end and bottom end of the post 1 in a freely circulating manner. And the endless chain 2 is circulated in such a manner that said chain 2 always descends at the front side of the post which moves forward together with the base machine 4. A solidifying agent is placed from the ground surface to the earth being cut at the descending side of the endless chain 2 and mixed and agitated with excavated earth by the cutting and agitating wings 3 thereby building a wall-shaped solidicied body.

摘要： PROBLEM TO BE SOLVED: To discharge earth and sand produced by excavation outside a ditch with higher efficiency by using the upward flow of an excavation liquid generated by the turning of a cutter chain. SOLUTION: A pipe-shaped earth removal space S is formed in an excavated area by a partition board S provided on a cutter post 3 substantially in an isolated state from a rear space. An upward flow of an excavation liquid A is generated by turning a cutter chain 6 in this earth removal space S while the earth and sand produced by excavation is floated on the flow of this liquid and discharged outside a ditch.

摘要： PROBLEM TO BE SOLVED: To hold a space as a culvert for a long period by providing a slit dredging knife arranged at a position opposite to the work progressing direction of an excavator, slit throttling body positioned in the intermediate section in the height direction and a casing. SOLUTION: When the motion of an excavation claw 25 shifts from rising process to lowering process, the soil placed on the excavation claw 25 is thrown aside in the direction opposite to work progressing direction from the window hole of a casing 21, forming a slit space S after the passing of a slit dredging knife 31. In the next step, since as the space formed by being held by both side plates of a slit throttling body 32 go far from work progressing direction, the width of the space S becomes narrow, the space S is throttled by both sides, being clogged at last and clogging the part directly under a lid H, which is formed by the soil laid aside. Then, a part of the space S and the space formed by the passing of a space forming plate 33 form a culvert under the throttled part. Since the culvert is isolated from the outside, being prevented from being clogged by the soil going in. Therefore, the space can be held for a long period.

摘要： PURPOSE: To easily restore a state in which the transverse motion, etc., of a cutter post is possible by causing auxiliary excavating bodies to move back and forth along the cutter post if the holding phenomenon of the cutter post occurs. CONSTITUTION: A number of main excavating blades 4 for excavating the ground are projected outward to both the right and left from an endless chain 2 stretched between the upper and lower ends of a cutter post 1. Auxiliary excavating bodies 7 having auxiliary excavating blades 10 are provided at both the front and rear of the cutter post 1 in such a way as to be free to slide vertically. If the holding phenomenon of the cutter post 1 occurs, a hydraulic cylinder 12 is driven, and the auxiliary excavating bodies 7 are guided by a sliding guide means consisting of a pit plate 9, etc., and are moved back and forth vertically along the cutter post 1. Then earth and sand, etc., settled and solidified inside a ventral space are dug and the earth pressure is reduced, so that a state in which the entire cutter can move transversely and the main excavating blades 4 can be rotated and withdrawn can be restored.
