摘要： PURPOSE:To enhance grooving accuracy by measuring the degree of the inclination of a support during groove drilling, and by reversing the moving directions of endless chains having a drilling blade when the degree of the inclination of the support exceeds the predetermined range, and by subsequently correcting the inclination of the support. CONSTITUTION:A sheet body P is interposed between endless chains 10A, 10B. The lower end of the sheet body P is positioned at the lower moving passage of a connecting material. Its upper end is held by means of the chuck of a cylinder for chuck. Next, the endless chains 10A, 10B are moved with pressing force against ground provided by means of a drilling device. A groove is drilled with cutting rotors 16A, 16B, 17A, 17B rotated. Next, the degree of the inclination of a support 4 is measured during groove drilling by means of an clinometer 22. A measuring from the clinometer 22 is inputted to an oil passage switching valve 23. When the degree of the inclination of the support 4 exceeds the allowable declined angle, oil passage switching is done by means of the oil passage switching valve 23 to reverse the moving directions of the endless chain 10A, 10B.

摘要： PURPOSE:To provide the stable motion of a travel carriage by supporting the carriage at three points with front and rear wheels fitted so as to come in contact with a rail at one side, and a single wheel fitted so as to come in contact with a rail at the other side. CONSTITUTION:The wheels 28a and 28b of a carriage 27 are kept in contact with one rail 14a of two-line track, while the wheel 28c kept in contact with the other rail 14b. When the carriage 27 has such a three-wheel structure, the wheel 28c follows a step, if any, on one rail 14b and is not derailed, regardless of a travel thereon. Also, if the other rail 14a has a step and the carriage 27 travels, the wheel 28a follows the stepped rail 14a and is not derailed. According to this construction, the carriage 27 can travel, properly following a laid rail, even when an irregular section appears thereon.

摘要： PURPOSE:To enhance workability by installing blade plates which move in the shaft center direction to the inside of a casing tube having cutting bits at the tip and installing the cutting bits to the blade plates. CONSTITUTION:When a casing tube 1 is rotated, cutting bits 2 try to cut earth and sand near the inner and outer peripheries of a casing 1. Then, cutting bits 4 of blade plates 3 and auxiliary cutting bits 6 of a center pole 5 cut the earth and sand inside the casing 1. Then, the cut and excavated sand and earth are introduced into the substantially angle-shaped blade plates 3 when side viewed and further into the casing 1 and then to the ground. When this excavation device is jacked underground consecutively and reaches a specified position, the casing 1 is filled with a stabilizing liquid, such as bentonite muddy water. After the casing 1 is further pulled off and a reinforcement cage is inserted into an excavated hole, concrete is cast, thereby forming a post wall for a column strip type earth retaining wall. This construction makes it possible to prevent the earth and sand in the casing from being deflected, and what is more, to jack up with high accuracy in the vertical direction.

摘要： PROBLEM TO BE SOLVED: To suitably relieve an unmanned vehicle stopped on a track. SOLUTION: Concerning a propulsion construction for starting a digging machine 22 from a starting pole 21 and successively allowing a propulsion pipe 23 to follow, in order to measure the position and attitude of the digging machine 22, an unmanned driven measuring vehicle 25 is used. The inner diameter of the propulsion pipe 23 is small and people can not enter frequently but with the unmanned measuring vehicle 25, the position and attitude can be exactly measured. When the measuring vehicle 25 is stopped on a traveling rail 24 because of a fault, it is extremely difficult to manually relieve it. An unmanned relief vehicle 20 is started from the starting pole 21 and it is judged whether the vehicle can be relieved or not while shooting its image with video equipment 27. The shot result is recorded by a recorder 28, reproduced and judged. When it is judged that the vehicle can be relieved, the relief vehicle 20 is connected to the measuring vehicle 25 and collects it.

摘要： PROBLEM TO BE SOLVED: To prevent various devices from injuring and effectively utilize muddy water and fresh water by leaving pebbles in lakes, marshes, and rivers, sucking only muddy water containing mud, and separating the muddy water into mud and fresh water. SOLUTION: After setting a mud collecting part A on mud 23, the muddy water passing body 3 of the mud collecting part A is rotated and a pump 4 is operated. As a result of this, muddy water 21 or disposal soil containing water content under fixed grain size is sucked from the through holes of the muddy water passing body 3, and it reaches a muddy water disposal device 5 on the ground 22 through a hose 6 for dredging. Namely, the muddy water passing body 3 makes a rigid distinction between disposal soil containing water content and pebbles, and collects treated soil. Next muddy water 21 and disposal soil containing water content are made sharp distinction between fresh water and muddy water containing organic substance by the muddy disposal device 5. The mud containing organic substance is utilized as fertile soil, after being accumulated. Meanwhile the fresh water is led to the mud collecting part A through a hose 7 for disposal fluid, peels off refuse stuck to the through holes of the muddy water passing body 3 so as to prevent the through holes from clogging.
