摘要： PURPOSE:To bond waterproof sheets by hot melting from the surface of the sheet by a method in which the surface of the sheet is exposed to electromagnetic field to detect hot-melt material and to detect the hot-melt position, and a given strength of electromagnetic field is applied to the detected position from the surface of the sheet. CONSTITUTION:A hot-melt material 12 is applied by coating or bonding to the back side of a waterproof sheet 11 of a long film form. The hot-melt material 12 is one formed by bonding a hot-melting resin 12b to both sides of a film-like heating layer 12a consisting of iron, aluminium, copper, stainless steel, brass, or ferromagnetic alloy. The hot-melt material 12 is also formed by dispersing the alloy powder uniformly into a resin.

摘要： PROBLEM TO BE SOLVED: To cut and hang down a lower loading section without conducting the cutting and extension works of a belt, and to perform day-and-night excavation and carry out soil and sand concentrically during the nighttime. SOLUTION: Soil and sand generated at the time of underground excavation are carried up to an upper expelling section 16 fixedly installed to an underground section in the vicinity of a ground surface while the lower loading section 1 of a first belt conveyor is lowered along a beforehand driven pile 19 as unfastening each excess-length absorbing section 12, 13 of a box-shaped belt 10 and a flat belt 11 as the components of the first belt conveyor 2, and temporarily placed in a hopper 5 mounted to a lower section. Temporarily placed soil and sand are conveyed out collectively onto the ground by a draw belt conveyor 7 and a second vertical belt conveyor 8.

摘要： PURPOSE:To enable the emergency ventilation automatically and surely after the blasting by setting airflow and time for ventilation with an emergency ventilating control section in the case a detection signal of a vibration sensor is in excess of reference value after the blast is executed in a tunnel. CONSTITUTION:A ventilating controller 10 is constituted of a fuzzy control section 11, an emergency ventilating control section 12 and an airflow 13, setting section and a detection signal from an environmental information detection sensor 7 is inputted to the fuzzy control 11. After that, fuzzy operations are made in a fuzzified section 14, a fuzzy theory section 15 and a non-fuzzified section 16. Increase and decrease of airflow is set in the airflow setting 13, and its signal is outputted to a ventilating fan 4. Then, a detection signal from a vibration sensor 8 is inputted in the emergency ventilating control 12, a vibration reference value decision section 17 and a blast detection section 18 detects whether or not the blast is executed, and in the case the blast is executed, emergency ventilation time is set by a timer setting section 19, and a signal set by the operation airflow setting section 13 is outputted to the ventilating fan 4. Reference value is decided by the vibration reference value decision section 17.

摘要： PROBLEM TO BE SOLVED: To obtain a cavity filler which can be filled, as a filler or a backfill material, into cavities at the crown side of a tunnel, etc., without fail, and enables a limited filling by compounding cement with a water-absorbing resin which absorb water and swells. SOLUTION: In the case of powder mixture comprising a water-absorbing resin and cement, the mixture absorbs injected water or natural inflow water after charged into a cavity, swells to fill it, and then solidifies. When some water is added to a mixture of the resin and cement is advance, the mixture becomes pumpable and expands in a cavity to enable a close filling. The incorporating of a water-soluble org. solvent into a compsn. contg. a water-absorbing resin and cement can give a flowable cavity filler which facilitates handlings such as transportation, pumping, and filling and enables a limited filling without causing voids even at the crown part of a tunnel. pref. the compsn. has an outflow ratio in water of 40% or lower and a flow value of 140-210.
