摘要： PROBLEM TO BE SOLVED: To control a ground-water level in a wide area. SOLUTION: Water-level indicators which are equipped with a communication function are installed respectively in ground-water observation wells 1 which are arranged in observation points in a region, to be controlled, in which a ground water current is clarified in advance. A person who intends to pump up ground water notifes a public office as a main control organization. In water pumping wells 2 it is required to install flowmeters which are equipped with a communication function and flow-rate controllers. The respective devices perform measuring operations at sampling intervals which are instructed from the computer of a control center 3, and they hold measured data, and they transmit the data to the control center 3 according to a request. The measured data are recorded and judged in a centralized manner in real time through the public line of NTT or the like. When a reference water level is lowered for a definite time or more, or when it is anticipated that the reference water level is lowered, proper water-pumping control measures can be taken automatically.

摘要： PURPOSE:To make corrugation unnecessary entirely and to keep airtightness by a method wherein a membrane is connected approximately at its middle part to steel plates that are joined to reinforcements of a body, and free ends of the membrane are held with heat-insulating materials. CONSTITUTION:Steel plates 3, 3, joined to reinforcements 2, 2 of a reinforced concrete body 1, are erected to the inside of the reinforced concrete bodies 1, 10. Then, metal membranes 4, 4 covering the internal face of the body 1 are joined approximately at their middle parts to the steel plate 3. Free ends of the membrane 4 are held with heat-insulating materials 5 that are interposed between the inside of the body 1 and the membrane. Peripheral edges of the membrane 4 are joined to the peripheral edges of adjoining segments 6, 6. Thereby, airtightness and liquidtightness on connecting parts S of the membrane 4 can be maintained while rupture of the membrane can be prevented because thermal expansion and thermal shrinkage of the membrane can be offset by deformation of the heat-insulating materials 5.

摘要： PURPOSE:To reduce the sorts of work and labor at the site, shorten the construction term, and reduce the construction costs by producing a ferro-concrete mass, heat insulation, and membrane at a factory in the form of segments of three-layer structure. CONSTITUTION:Heat insulation 2 is arranged on the inside surface of a ferro-concrete mass 1, and a membrane 3 is installed on the inside surface of the insulation. The membrane 3 is furnished with wrinkled corrugation 4 stretching striding the position of a joint 5 as a surplus portion so that expansion and contraction due to temp. change are absorbed. The tip 6 of this corrugation 4 is subjected to a whole circumference welding 9 so that the air-tightness of the membrane 3 is retained. This enables producing a segment of three-layer structure consisting of ferro-concrete mass 1, heat insulation 2, and membrane 3 in advance at a factory in a single piece structuring.

摘要： PURPOSE:To safely execute the replacement of worn bits in a short time in long-distance shield tunneling works particularly applied to a gravel bed. CONSTITUTION:In a shield machine 3 provided with a second partition wall 2 for supporting the muddy water pressure of a facing in a shield main body located on the inner side of a cutter face 1, a spoke portion 5 having bits 7 is separated from the cutter face 1 and is moved back together with a rotary shaft 4. The spoke portion 5 passes through the second partition wall 2 too and is moved back as far as in a first chamber 11 between the second partition wall 2 and a first partition wall 10. The shutters of the cutter face 1 and time second partition wall 2 are closed and a water cut-off material 13 such as rubber or a synthetic resin is filled in a second chamber 12 between the cutter face 1 and the second partition wall 2. Then, water pressure in the first chamber 11 is decreased. Drainage is carried out to form an air space. A worker 14 enters in the first chamber 11 to replace the bits 7 attached on the spoke section 5.

摘要： PROBLEM TO BE SOLVED: To correct the nonconformity of a pumping control system to the nature of ground water. SOLUTION: The levels of water in pumping wells W equipped with motor-driven valves 8 positioned at a few points and water in observation wells located at a few points to correspond to the pumping wells W are measured by means of monometers 9 and the like, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening so that the difference between a set level of water and a measured level of water is dissolved. When the difference (well loss) in level of water between inside and outside of the casing of the pumping well W is large and when the rate of decrease in level of ground water is slow, the amount of water pumped from each well is measured with an electromagnetic flowmeter 12 or the like, and the permeation characteristic of the ground required to estimate the relationship between the flow rate of pumped water and the level of the ground water is automatically calculated through reverse analysis from the measurements of the amount of water pumped from the pumping well W and the level of water in the observation well A during system operation. The present level of the ground water is estimated from the measurement of the amount of water pumped, and the aperture of each motor-driven valve 8 is automatically controlled in real-time at an accuracy of 0.1% for a 100% of fully opening, so that the difference between the present level of the ground water and the set level of the ground water is eliminated.

摘要： PROBLEM TO BE SOLVED: To enable simple and highly accurate shearing tests by attaching the ends of a plurality of belt-shaped tension members to the peripheral surface of a test piece of hard material formed in a cylindrical shape along shearing surfaces in the opposite directions, attaching the other ends to jigs, and causing shearing in the specimen. SOLUTION: Hard material is formed into a cylindrical test piece 1, and the end of a plurality of belt-shaped circular tension members 2, 2, and 3 are attached to the peripheral surface of the test piece 1 at right angles to its axis each along shearing surfaces 4 and 4 in the opposite directions. The belt- shaped tension members 2, 2, and 3 are preferably belts, etc., produced of freely deformable material such as a carbon fiber composite material with characteristics that no expansion or fracture is developed due to the load of shearing tests. By attaching the other end of the belt-shaped tension members 2, 2, and 3 each to the peripheral surfaces of cylindrical jigs 5 and 6 and pulling the belt-shaped tension members 2 and 3 in the opposite directions via the jigs 5 and 6, shearing along the shearing surfaces 4 is caused in the test piece 1.
