摘要： PROBLEM TO BE SOLVED: To increase the quantity of outflow soil and sand adjusted of a checkdam by installing a water channel component so that a water channel is extended on a river-bed towards a dam upstream from the drip holes, etc., of a dam bank body and constructing a lining cylinder type screen body covering the water channel in a tunnel shape while using the water channel component as a foundation. SOLUTION: A lining cylinder type screen culvert body 51 is constituted of a water channel component functioning as a foundation in combination and an approximately rectangular or approximately trapezoidal tunnel-shaped screen body 53 having a header cross section having one piece in length of 2-4m and the same cross section in length of 20-50m. The lining cylinder type screen culvert body 51 is combined with a concrete checkdam 50, to which a large-sized drip hole, etc., 9 in a sediment flow or a bed-load transport region are formed, and the header surface of the screen culvert body 51 is joined with the drip hole, etc., 9 of the checkdam 50 on an original river-bed in an accretion sand region in a flow just above the checkdam 50, and the screen culvert body 51 is arranged in the longitudinal direction of a river. Screen clearances are set according to the grain size of outflow soil and sand as the coarse screen clearances in the flow section 54 just above a dam bank body and the fine screen clearances in an upstream section 55, and changed in the longitudinal direction.

摘要： PURPOSE:To perform the filling of a filler into the clearance between a reinforcing inner sheath pipe and upper steel pipe pile and a lower steel pipe pile as a series of work at the same point of time, and significantly reduce the cost to a conventional technique. CONSTITUTION:A putty-like filter 9 which never flow and is variable in form until solidified is preliminarily mounted on the outer surface 10 of a reinforcing inner sheath pipe 4, the upper end 2 of a lower steel pipe pile 1, and the lower end 4 of an upper steel pipe pile 3. The filter 9 is automatically filled in the clearance between the lower steel pipe pile 1 and upper steel pipe pile 3 and the reinforcing inner sheath pipe 5 only by inserting the reinforcing inner sheath pipe 5 into the upper end of the lower steel pipe pile 1 and the inner cavity 13 of the lower end 4 of the upper steel pipe pile 3.

摘要： PURPOSE:To obtain the inexpensive grinding and sweeping material exellent in grinding and sweeping properties, by blending blast furnace slag. CONSTITUTION:The so-called blast furnace water granulated slag that is obtained by rapidly cooling blast furnace slag is made up of a crystaline material and a vitreous material and the vitreous material is predominantly present therein. The blast furnace water granulated slag itself is not suitable to substitute for a steel surface grinding and sweeping material because its strength is low. In the present invention, a blast furnace slag is blended with a converter slag and then water-granulated to improve the water granulation strength to the optimum value as a grinding and sweeping material. Particularly, in densifying and rigidifying the blast furnace slag with the converter slag, to suppress the disintegration of the water granulation which is unfavorable to grinding and sweeping, the amount of the converter slag to be added is restricted up to 7wt%. As a result, the grinding and sweeping material having a long life and excellent in grinding and sweeping properties can be obtained.

摘要： PURPOSE:To easily perform an extension of steel pipe pile as a work at the same point of time in a constructing site, insert both vertical ends of a reinforcing inner sheath pipe into the upper end of a lower steel pipe pile and the lower end of an upper steel pipe pile, remarkably reduce the working cost of a follower pile for steel pipe pile, and significantly extend the applicability of this construction method. CONSTITUTION:A steel pipe pile is formed of a reinforcing inner sheath pipe 5 having screw holes 7 provided at longitudinal intervals, a lower steel pipe pile 1 having round holes 8 slightly larger in diameter than the screw holes 7 of the reinforcing inner sheath pipe 5 on the upper end part, an upper steel pipe pile 3 having round holes 8, 9 slightly larger in diameter than the screw holes 7 of the reinforcing inner sheath pipe 5 on the lower end part, and bolts 11 having holes smaller in diameter than the respective round holes 8, 9 of the lower steel pipe pile 1 and upper steel pipe pile 3. After the reinforcing inner sheath pipe 5 is inserted to the inside of the lower steel pipe pile 1 and upper steel pipe pile 3, the bolt 11 with hole is passed through each round hole 8, 9 in the lower steel pipe pile 1 and upper steel pipe pile 3, and further screwed into the screw hole 7 of the reinforcing inner sheath pipe, whereby the reinforcing inner sheath pipe 5 is fixed to the joint part between the lower steel pipe pile 1 and upper steel pipe pile 3.

摘要： PURPOSE:To control the thickness ratio distribution of the ore/coke layers in a blast furnace and to stabilize blast furnace operation by detecting the raw material layer thickness in the diametral direction of the furnace owing to the collapse of the raw material layer charged into the furnace and feeding the same back to a raw material charger. CONSTITUTION:A bell 1 is lowered in a blast furnace having a bell type raw material charger and coke 2 which is a reducing agent and iron ore 3 are charged alternately in a laminar state into the blast furnace. The coke near the furnace wall part is chipped by the ore 3 falling by striking against the furnace wall as the iron ore 3 charged thereafter into the furnace falls, thus the coke layer 2 moves along the sliding line 5 toward the central part of the furnace. The thickness of the coke layer in the inside diametral direction of the furnace changes accordingly and the distribution in the thickness ratio of the ore-coke layers changes. The flow rate of the gas ascending in the furnace changes in the inside diametral direction, thus making the furnace condition unstable. Such change in the coke layer is fed back to the raw material charger and the raw materials are charged in a way as to maintain the specified thickness ratio distribution of the ore-coke layer in the furnace, by which the furnace condition is stabilized.
摘要翻译：目的：为了控制高炉矿石/焦炭层的厚度比分布，并通过检测原料层在炉内径向方向上的厚度，稳定高炉操作，由于原料层被倒入加热炉并将其送回原料充电器。构成：在具有钟形原料充电器和作为还原剂的焦炭2的高炉中降低钟形1，并将铁矿石3以层状交替地装入高炉。炉壁部分附近的焦炭随着随炉送入炉中的铁矿石3撞向炉壁而被矿石3砸碎，因此焦炭层2沿着滑动线5向炉的中心部分移动。炉内径方向焦炭层的厚度相应变化，矿焦层的厚度比分布变化。在炉内上升的气体的流量在内径方向上变化，从而使炉状态不稳定。将焦炭层中的这种变化反馈到原料充电器，并且以保持炉中的焦炭焦炭层的规定厚度比分布的方式填充原料，由此使炉条件稳定。
