    • PROBLEM TO BE SOLVED: To detect the presence of water without breaking a surface layer, by heating the water within an asphalt surface layer by a microwave oscillator, and continuously monitoring and recording the temperature difference from a position free from water by an infrared camera. SOLUTION: To detect the internal water of a surface protecting layer 11 of asphalt or the like, a traveling vehicle 1 is gradually run on the surface protecting layer 11, the position of a microwave oscillator 9 is regulated by a height regulating device 14, and microwaves are emitted to the surface protecting layer 11 through a wave guide 10. The temperature is raised in the position where water is present within the surface protecting layer 11 to cause a temperature difference from the position free from water. This temperature difference is picked up by an infrared camera 8 height-regulated by a height regulating device 15, displayed on an indicator 4, and continuously monitored. In this monitor image, for example, the water part is suddenly raised in temperature and displayed by red, and the asphalt part is not raised in temperature so much and displayed by blue. According to this, the presence of water can be detected.

    • PROBLEM TO BE SOLVED: To construct a mass concrete structure of the required strength at high workability by applying the constitution that high fluidity concrete having the prescribed slump flow range is placed in the placement space of existing concrete in advance, and curing the high fluidity concrete after supplying coarse aggregate thereto. SOLUTION: First, placement space 2 using existing concrete 1 as a bottom part is formed, and the side of the space 2 is made by use of a form. At the process of the prior placement of high fluidity concrete, preferably lime stone powder or the like is used to substitute a part of cement and high fluidity concrete 3 blended with a thickener and prepared to have a slump flow between 60 and 80 cm is placed in the space 2. Thereafter but before the lapse of long time, coarse aggregate 4 is supplied to the high fluidity concrete 3 from an upper position. As a result, the level of the placed concrete rises and in this case, placement height after the supply of the coarse aggregate 4 is preferably set at a level approximately between 50 and 100 cm.

    • PURPOSE:To continuously and economically construct a concrete facing on the slope of a dam as well as greatly shorten the period of the construction by running vertically a paving machine on the slope of the dam. CONSTITUTION:An uncured dry-consistency fiber concrete is delivered onto the top 1 of a dam by a dump truck 2 and a facing concrete is continuously constructed in a belt-like form by means of a paving machine running vertically on the slope. The paving machine consists of a finisher 3 to be dragged by a main winch porter and a vibrating roller 4. The face of foundation is compacted by a dumper vehicle 6 while delivering concrete. The vibrating roller 4' for finishing and compaction is dragged for final compaction and a joint cutter is run before the concrete is hardened following the compaction.
    • 目的:要持续经济地建设一座大坝边坡上的混凝土,并大大缩短施工期,在大坝边坡上垂直铺设一台铺路机。 规定:未固化的干稠度纤维混凝土由自卸车2输送到大坝的顶部1,并且面向混凝土通过在斜坡上垂直运行的铺路机连续构成带状形式。 摊铺机由一个由主绞车搬运工和一个振动辊4牵引的整理机3组成。在输送混凝土的同时,基础面被一个自卸车6压实。 用于精加工和压实的振动辊4'被牵引用于最终压实,并且在压实之后在混凝土硬化之前运行联合切割机。
