摘要： PROBLEM TO BE SOLVED: To efficiently recover cutting chips of a dry cutter and facilitate disposal of recovered cut chips.
SOLUTION: An air blower 3 is started, an air flow is injected into a cutting groove from a blowoff port 40 and a blade 1 is cooled while generated cut chips are blown off and suspended in air. Since a valve 42 is throttled and the volume of air injected is reduced and made smaller than the volume of air sucked and the outside air is sucked to the inside from an opening between the skirt of a blade cover 10 and a road surface, cut chips do not leak from the opening. Since cut chips reach a cyclone 2 from a suction duct 11, are separated and deposits on a bottom section, a bottom plate 21 is opened and recovered into a dust collecting bag 23. Since the suction air flow is returned to a suction port for the air blower 3 through a filter 4 and circulated, an exhaust is not discharged to the outside air, and an environmental pollution can be reduced largely, and the frequency of the exchange of the filters is decreased because cut chips are separated by the cyclone 2.

摘要翻译：要解决的问题：有效恢复干式切割机的切屑，便于处理回收的切屑。解决方案：启动鼓风机3，从吹出口40将气流注入切割槽中，并且在产生的切屑被吹出并悬浮在空气中的同时冷却叶片1。由于阀42被节流并且喷射的空气的体积减小并且小于吸入的空气的体积，并且外部空气从叶片盖10的裙部和路面之间的开口被吸入到内部，所以切割的切屑不要从开口泄漏。由于切割的切屑从吸入管道11到达旋风分离器2，所以分离并沉积在底部部分上，底板21打开并回收到集尘袋23中。由于吸入气流返回到吸入口鼓风机3通过过滤器4并循环，排气不会排出到外部空气中，并且可以大大降低环境污染，并且由于切割的碎屑被旋风分离器2分离，所以过滤器的更换频率降低。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To allow a device for cutting and grooving a road surface to quickly collect from within a housing the dust generated during operations and to achieve efficient cutting and good construction work while keeping a blade from being heated. SOLUTION: This device has a scavenging means which force-feeds air into a housing 3 fitted to a main body, while the rotating direction of a blade 9 covered with the housing 3 is aligned with the direction to scrape a road surface layer upward with respect to the advancing direction of the device, and which sucks the air from the downstream side of the housing 3. Thereby air containing dust can be collected without dissipating to the outside from the housing 3.

摘要： PROBLEM TO BE SOLVED: To remove a bridge girder formed of precast concrete girder in a short period and at a low cost by preventing cooling exhaust water from outflowing into the environment by reducing cut sections necessary for cooling water.
SOLUTION: Both ends of a PC steel member 11 where mutual precast concrete girders 1 are tightly connected are cut off to make free the connected state. A cutting groove 3 with 15 cm depth is formed by a cutter in an infilling concrete 2 between the precast concrete girders 1, spring out cooling slurry water is suck out by vacuum to collect the whole slurry water so as not to outflow into the environment. Plate jacks 4 are set at every appropriate interval in the cutting groove 3. A liquid is injected with a pressure into the plate jacks 4 to expand them and separate the precast concrete girders 1 of the side ends. The separated precast concrete girders 1 are lifted up by a crane and remove them. Respective precast concrete girders 1 are removed by repeating the process.

摘要： PROBLEM TO BE SOLVED: To make it possible to recycle the sludge generated during cutting of paved road surfaces, etc., by a high-speed rotary cutter by subjecting the sludge to a solid-liquid separation and to make an apparatus compact and movable. SOLUTION: A water tank 1, an agitating vessel 2 and a settling vessel 3 are integrated and the water sent from the water tank 1 to the cutter 31 is sucked and is fed into the agitating vessel 2. Simultaneously the diluting water is sent from the water tank 1 to the agitating vessel 2 and the sucked sludge is diluted to a concentration at which a flocculation reaction takes place easily. The flock formed by injection of the flocculating agent from a flocculating agent tank 40 and agitation by an agitator 13 flows over the settling vessel 3 and is subjected to the solid-liquid separation. The treated water is collected in an overflow trough 17, is dropped by gravity, and is returned to an auxiliary settling vessel 19. The treated water is stored in the water tank 1 and is recycled.
