摘要： PROBLEM TO BE SOLVED: To reduce soil improvement works to the minimum by disposing a concrete slab on a roadbed with its convex or concave surface arranged on the roadbed side, and laying the concrete slab such that at least part of the convex or concave surface side cuts into the roadbed. SOLUTION: A concrete slab 10 is produced by arranging forms 14 on a flat upper surface of a stand 16, arranging at least one reinforcement or steel frame in each form 14, placing ready mixed-concrete 18 in the form 14, forming an upper surface of the ready mixed-concrete 18 into a convex surface 12, and thereafter curing the ready mixed-concrete 18. The concrete slab 10 is disposed with its convex surface 12 arranged on a roadbed side, and laid such that at least part of the convex surface 12 side of the concrete slab 10 cuts into the roadbed. Thus, the concrete slab 10 exerts reinforcing effect with respect to the ground, and a load is dispersed and smoothly transferred. As a result, an effect which is similar to one exhibited by the soil improvement of the construction site and the vicinity thereof can be exerted, and therefore soil improvement works can be drastically reduced.

摘要： PROBLEM TO BE SOLVED: To improve safety by launching earth retaining face plates provided in the face plates of a shield machine, and removing obstacles while retaining earth for which ground improvement has been made in advance. SOLUTION: Earth retaining face plates 18 are arranged in recesses provided in the face plate of the front face of a shield machine 11 in a rotationally symmetrical state and are made withdrawable with an earth retaining face 21. At the time of excavation, the face plates 18 are withdrawn into the recesses and slits 16 are opened, the surfaces of the main body 12a of the face plate and the face plates 18 are positioned flush with each other, and the edges of bits 14 are projected forward from the face plate 12. When an obstacle such as an H-steel pile has appeared in the safe, excavations is suspended, the face ground is improved and the surfaces of the face plates 18 are pushed out as far as the heads of the bits 14, and earth is retained by pressing the face. And then the obstacle is cut and recovered with a water jet cutting and recovery unit 23, after the slits 16 are blocked by shutting opening/closing plates 15, mud water in a chamber is removed, and an iron plate 22 is removed. the face can be stabilized without applying compressed air, and accidental air blow can be prevented.

摘要： PROBLEM TO BE SOLVED: To troubleshoot the hazards of a prior art water bottom construction method which demands for a large-scale work and immeasurable construction cost and blocks a water area temporarily during construction time and affect a route immensely and contaminates the sea during construction time. SOLUTION: While the soil under the water level is being excavated with an excavating machine 1, a plurality of boxes 2a, 3a to 4a added to the rear part of the excavating machine 1 are buried by propulsion. During this work, there is formed an operation space which feeds water or drain water between a forward box located at the front position and a backward box located at the rear part of this box. The water prevailing in the front-sided operation space of the box to be propelled is drained and depressurized, thereby opening the enclosure of the rear sided operation space 15 and enabling water to be supplied. This construction makes it possible to propel the boxes based on the differential pressure of the rear-sided operation space 15.

SOLUTION: Upper surface side two main reinforcements 2 parallel in the longitudinal direction, are arranged at a predetermined interval in the width direction of a precast slab. Under surface side one main reinforcement 3 is arranged in the middle in the width direction of the upper surface side main reinforcements 2. The upper surface side main reinforcements 2 and the under surface side main reinforcement 1 are fixed by an oblique reinforcement continuously formed in the longitudinal direction, and is fixed by a horizontal reinforcement 40 formed in an S shape continuing in the longitudinal direction from the upper surface side of the upper surface side two main reinforcements 2. A truss reinforcement joining body of a triangular shape in a cross-sectional view, is constituted of the upper surface side main reinforcements 2, the under surface side main reinforcement 1, the oblique reinforcement 4 fixing these reinforcements and the horizontal reinforcement. The reinforcement joining body is arranged at the predetermined interval in the width direction of the precast slab, and high strength concrete is placed.
