摘要： PURPOSE:To efficiently bury a pipe by fixedly burying back a groove on a space ensuring member, drawing a buried pipe into the groove to be arranged and filling a cavity between the space ensuring member and the buried pipe with a filling agent. CONSTITUTION:A groove 2 of depth D is formed by digging the ground 1. Next, a U-shaped side groove 5, consisting of concrete and steel material or the like and having a hollow part 4 as a space ensuring member, is set up in a groove 2 so that an upper part of the groove 5 is covered. The U-shaped side groove 5 is fixed by burying back, its upper part with earth sand 6. After the groove 2 is buried back, a piping and connecting groove 8 is excavated in a piping work part, and a pipe 3 is drawn into this groove 8 and arranged by connection through welding or the like. Thereafter, the pipe 3 is fixed by filling the hollow part 4 between the pipe 3 and the U-shaped side groove 5 with a filling material 9. In this way, piping work can be easily and promptly performed.

摘要： PURPOSE:To obtain a displacement value which is very close to a real value by correcting all acceleration data with a mean value and integrating them to find a speed, correcting all speed data while regarding such an axis that the mean value of the speed data is zero within a range wherein displacement is originally constant as a reference line, and weighting and integrating the data. CONSTITUTION:Mean values of every 5-6 pieces of acceleration data are found and their mean value is used as a reference axis to correct and integrate all the acceleration data, thereby obtaining a chart (a) of the speed. Here, the actual displacement is as shown in a figure (b) and the speed should be zero within a range R. The reference axis S which is parallel to the inclination of speed data within the range R as shown in a figure (c) and sets the mean value of the speed data within the range R to a zero point is found and all the speed data is corrected based upon this reference axis. Further, the speed data within the range R are multiplied by a coefficient 1-e N for weighing and then integrated to obtain the waveform of displacement extremely close to a real waveform (b).

摘要： PURPOSE:To provide a pipe embedding method that is inexpensive in construction expenditure, less in a traffic obstruction due to construction, high in working efficiency and makes it applicable even in a distance between long intervals. CONSTITUTION:A keyway-form ditch using a spherical part as the bottom part lying between a starting side shaft and an arrival side shaft constructed at both sides of a pipe embedding predetermined position is dug by a chain type ditching machine 28 with a pair of semispherical drums 41 and 42 attached with a lot of bits 43 on the circumference. After a pipe is arranged in the spherical bottom part of the keyway-form ditch dug out from a pit mouth, the keyway-form ditch arranged with the pipe and each shaft are refilled.

摘要： PURPOSE:To improve workability in burying of pipes by a method wherein a pavement crushing and discharge device, an excavating device, a dehydration and improvement device, a pipe laying device, a filling-back device and a paving device are installed in line under an overpassing road bridge that is supported with wheeled trestles with its opposite ends placed touching the road surface. CONSTITUTION:An overpassing road bridge 1 supported with a plurality of wheeled trestles 3 is constructed, with opposite ends thereof placed touching the road surface, over a road 4 wherein pipes 13 are to be laid. While the overpassing road bridge 1 is opened to traffic, a series of pipe-laying works is executed in succession by operation of various device installed in line under the road bridge 1. The devices include: a pavement crushing and discharge device 5 that is composed of a crushing means 6 and a discharge means 7, an excavating device 8 that is composed of an excavating means 9 and a conveying means 10, a pipe-laying device 12 that is composed of a pipe storing means 14 and a pipe joining means 17 and filling-back device 18 that is composed of a soil supply means 19 and a compacting means 20. In addition to the above-mentioned devices, a paving device 21 and a dehydration and improvement device 11 are installed. Thereby costs for execution of work can be reduced.

摘要： PURPOSE:To exactly obtain the penetration and rebound amounts of a pile immediately by a method in which a change in acceleration when driving a pile is measured by an accelerometer attached to the pile, and the change of acceleration so measured is subjected to two times' integration in an integrator to calculate the amount of displacement. CONSTITUTION:An accelerometer 10 is attached to a pile, a change of acceleration is measured each time striking is applied by Diesel hammer, etc., and the measured values are sent out to an integrator 2. The output of acceleration is subjected to two times' integration in the integrator 10 and converted into displacement output, and the displacement output is sent out to a recorder 3. The signals of displacement from the integrator 2 are recorded on a paper by the recorder 3 and displayed. The penetration and rebound amounts of the pile can thus be exactly obtained immediately.

摘要： PURPOSE:To measure the size of a cavity with good accuracy even when ground water and air exist so as to be mixed insdie a cavity produced around a structure or direclty under the structure. CONSTITUTION:While a hull 4 is floated and propelled on ground water inside a cavity around a structure or direclty under the structure, laser beams are radiated from one pair of laser oscillators 5a, 5b. Bright spots formed when the individual laser beams hit the upper surface or the bottom surface of the cavity are always monitored by a TV camera 8. Radiation angles of the laser beams are made variable by a beam-angle variable means 7 in such a way that the bright spots of the laser beams as one pair coincide. When the bright spots of the laser beams as one pair coincide, the radiation angles of the laser beams are computed, and distances up to the bright spots of the laser beams are computed. When this processing is repeated sequentially, the size of the cavity can be detected.
