摘要： PROBLEM TO BE SOLVED: To prevent the generation of deep excavation more than required when the revolution of an injection nozzle is stopped and a lateral shifter is stopped. SOLUTION: The road-surface treatment working machine has a high-pressure water injector with a driving device rotating an injection nozzle 23, into which high-pressure water is forwarded by a high-pressure pump 51, and a lateral shifter 21 laterally moved to the left and the right along a long-sized guide member 11 in the car-breadth direction installed to a machine body. Injection pressure from the injection nozzle 23 is changed over to low pressure by a changeover control means 55 on the basis of detecting sensors 53, 54 detecting the stoppage of either one of the driving device or the lateral shifter 21 when either one of the driving device or the lateral shifter 21 is stopped and detecting signals from the detecting sensors 53, 54.

摘要： PROBLEM TO BE SOLVED: To improve work execution properties by installing a template along a road carriageway marking of the mixture for pavement, and detaching the template from a road surface after the rolling compaction. SOLUTION: After the mixture for pavement such as ASCON of small grain size is laid, a template is installed along a carriageway marking provided on right and left sides of a paved road surface. The road surface is roll-compacted by a tamping machine such as an asphalt finisher to press the template into the paved surface, the template is detached from the road surface to form a groove in the road surface. The template is formed of a flat member having the pattern of the wire member such as wire corresponding to the groove, and the whole or at least a part of the template is flexible, and the template is formed by connecting a part in the longitudinal section along the vehicle advancing direction to a part orthogonal thereto at one or two parts. Continuous grooves to draw a driver's attention can be easily and surely formed, and the template is recyclable so as to be subjected to low-cost work execution.

摘要： PROBLEM TO BE SOLVED: To improve excavation work efficiency by peeling off the repair part of a surface layer having a crack or the like through a one-time travel, regarding a pavement. SOLUTION: This excavation work vehicle for a pavement has a rotary excavation and discharge means 3 to form an excavation channel on the surface of a pavement and to discharge crushed pieces, as well as a carrying means 30 to receive the crushed pieces from the rotary and excavation and discharge means 3 and then to carry the crushed pieces outside the vehicle. In this case, the excavation work vehicle is formed so that the rotary excavation and discharge means 3 is free to expand and contract in the breadthwise direction between a position beyond vehicle breadth and another position within the vehicle breadth.

摘要： PROBLEM TO BE SOLVED: To keep a guide member in a correct position without being influenced by the travel of the machine. SOLUTION: A guide member 13 provided at a self-advancing machine body 11 and long in a cross direction is provided with a high pressure water jet device 3 having a jet nozzle laterally movable along the guide member 13, and detecting sensors 35, 37 brought into contact with a guide reference body 59 disposed along a longitudinal direction, so as to detect the orthogonal angle of the guide member 13 orthogonal to the guide reference body 59, in at least two places. A movement control device 33 is provided to move the guide member 13 in a cross direction in relation to the machine body 11 on the basis of detection signals from the detecting sensors 35, 37 and a turn control device 31 is provided to rotate the guide member 13 by a prescribed angle. The guide member 13 is always positioned in a correct position by the control device 31 and the movement control device 33.
