摘要： PROBLEM TO BE SOLVED: To measure the quantity of excavated earth precisely on real time by connecting a measuring pipe supported at two point through a flexible joint in a pipe for transferring excavated earth and sand and measuring strain due to the excavated earth and sand. SOLUTION: Earth and sand excavated by a shield excavator is discharged from within a chamber and passed through a transfer pipe so as to be carried out onto the ground. An electromagnetic flowmeter is provided in the transfer pipe to measure the flow rate Q of earth and sand. A measuring device for measuring physical quantity in pipe is mounted in the pipe. The opposite ends of a measuring pipe 32 are supported on a pair of supporting bases 36. The pipe 32 is deflected downward corresponding to gravitation and weight of earth and sand in the pipe. The strain of the pipe is measured by a strain gage 34, whereby density and weight of the earth and sand transferred through the pipe 32 can be measured on real time.

摘要： PROBLEM TO BE SOLVED: To measure a discharged earth-and-sand amount with high accuracy by a method wherein information regarding the filling degree of earth and sand to be filled into an earth-and-sand force-feed pipe is detected and the flow rate of the earth and sand is found on the basis of the information. SOLUTION: Information regarding the filling degree of earth and sand to be filled into a force-feed pipe which force-feeds earth and sand escavated by a shield excavator is detected by a detection means 10, and a flow-rate detection means 20 computes the flow rate of the earth and sand on the basis of the information. A force-feed-time measuring part 30 measures the force-feed time of one piston operation of a force-feed pump. A flow-velocity detection means 40 detects the flow velocity of the earth and sand inside the force-feed pipe, and a density detection means 60 measures the density of earth and sand discharged by the force-feed pump. On the basis of respective measured results, a volume computing part 50 and a weight computing part 70 compute the volume and the weight of the discharged earth and sand, and respective computed results are displayed or printed on a display part 80 or a printer 82. By this method, even when a gap or the like id generated inside the force-feed pipe, it can be compensated by the filling degree, and a flow-rate value can be measured precisely.

摘要： PROBLEM TO BE SOLVED: To make it easy to keep balance at the time of incoming and outgoing and facilitate climbing up and down by providing a plurality of ladder parts at a base part installed at an opening part of a manhole, and erectly providing a supporting part with its upper end formed in a L-shape and provided with a locking part. SOLUTION: A climbing-up-and-down frame 1 is composed of a base part 2 and a supporting part 3 of specified height. The base part 2 has connected parts formed on one end side of side parts 4 opposed with an appropriate space. A caster 7 is fitted to one end part of each side part 4. The supporting part 3 is provided with a plurality of ladder parts 8 with specified spaces. The side parts 4, connected parts and supporting part 3 are respectively formed of steel such as channel steel. A U-shape locking part 10 for conveying material and the like into a manhole 13 and unloading is fitted to the lower end part of an L-shape part 9. The side parts 4 are positioned in the state of being laid across an opening part 14 of a manhole 13, and the climbing-up-and-down frame 1 is installed in the aligned state of the ladder parts 8 and ladders 5 in the manhole 13. Movement is therefore simplified, and climbing up and down is facilitated so as to improve in safety.
