摘要： PROBLEM TO BE SOLVED: To prevent a pile from breaking owing to horizontal forces and bending moments from the upper construction. SOLUTION: A pedestal 2 is fitted at the top of a pile 1 and legs 4 fixed to the upper construction are put on the pedestal 2 to form a vibration isolation structure. And the sliding plate 5 fitted to the lower end of the legs 4 is positioned to contact the pedestal 2 and the legs are supported so as to slide on the pedestal. A circular outer seal 21 made of a flexible material is fitted to the peripheral edge of the sliding plate 5 and a circular inner seal 22 is fitted to the underface of the sliding plate 5 of the inside thereof. The circular outer seal 21 is provided with such a structure that it can follow up to fill a gap even if it is brought between the pedestal 2 and the sliding plate 5. A hole for a nozzle 23 is cut at the nearly central part of the sliding plate 5. When a specified pressure drop is brought at the nearby position of the outlet of nozzle 23, high pressure air and air bubble are ejected from the nozzle 23.

摘要： PURPOSE:To permit primary construction of covering soil to be automatically and efficiently performed by excavating a tunnel of contour larger than a shield main unit by a cutter head generating a loosened region simultaneously injecting a quick-setting filling material into the loosened region. CONSTITUTION:While propelling a shield main unit 1, a tunnel of contour larger than the outside diameter of the main unit 1 is excavated by a cutter head 2 in its front face bit 6 and peripheral part overcutter 6, and the natural ground in the periphery is loosened. Further simultaneously with the excavation, a filling material of cement is jetted to a loosened area 10 from an injection hole 11 in a back part of the cutter 6 and mixed with the earth and sand. A quick-setting agent is jetted to the periphery from two or more injection holes 15 in the periphery of the main unit 1, mixing with the cement in the filled loosened area 10 and quickly solidifying the cement. Thus simultaneously performing excavation progress of the tunnel and the primary construction of covering soil, elimination or reduction of labor, saving of material and the high speed of construction can be contrived.

摘要： PURPOSE:To provide a conveyance method by a vertical screw conveyer and the vertical screw conveyer which can convey an article to be conveyed in a casing up wards perpendicularly with high efficiency by improving the charging rate of the article to be conveyed. CONSTITUTION:This vertical screw conveyer is provided with a cylindrical easing 1 which is made to stand perpendicularly, a rotating shaft 2 which passes through the upper and lower parts of the easing 1 and is shaft-supported so as to rotate, and a spiral-shaped screw 4 which is arranged integratedly at the outer periphery of the rotating shaft 2. Irregularities 7 are formed in the inner wall surface of the easing 1, and a sliding surface covered with Teflon 8 is formed in the outer surface of the screw 4 to set a friction coefficient between earth and sand 5 which is conveyed inside the easing 1 and the inner wall surface of the easing 1 so that it may be higher than that between the earth and sand 5 and the surface of the screw.

摘要： PURPOSE:To exhaust the soil and sand from excavation easily to outside a hole and maintain the function of exhausting the soil and sand easily even though the hole in excavation becomes long, by including bubbles in the soil and sand with no use of any foaming agent, and improving the fluidity of the soil and sand. CONSTITUTION:A water-soluble high polymer solution is fed to the tip of a drill 2 together with compressed air via a hose 10 and communication holes 3a, 5a and spouted from near the tip of the drill 2, and thereby the solution is turned in bubbled state and included in the soil and sand excavated between the drill 2 and the surrounding natural ground to perform hole excavation.

摘要： PURPOSE:To permit the primary construction of covering soil to be performed within the shield digging time by excavating the ground to be spread with a large contour rotary drum, provided in the intermediate part of a shield main unit, and mixing quick setting concrete in the natural ground earth and sand loosened in a doughnut shape. CONSTITUTION:While propelling a shield main unit 1 to be advanced, a tunnel is excavated by a cutter head 2, simultaneously digging earth and sand in the outside of the main unit 1 by a peripheral cutter 5a of a rotary drum 5 with a diameter larger than the main unit 1 mounted between a front barrel 1a and a rear barrel 1b, the periphery of the tunnel is spread in its size. Next in the loosened earth and sand excavated into a doughnut shape, concrete or the like of arrow head A, mixing a quick setting agent and flash setting agent of arrow head B, is mixed through many concrete depositing pipes 15, and a fin 5b stirs the concrete to be solidified. Thus concurrently performing excavation advancing of the tunnel and primary soil covering construction, it can be performed within the shield digging time.
