BREAKING PREVENTION EQUIPMENT AND BREAKING PERCEPTION SENSOR OF WELL BOX BASIS FOR BRIDGE

摘要

The present invention and the well base is located at the bottom of the pier fixed to the rock bed underwater; The inner circumference surrounds the bottom of the well base and the lower part of the piers, and the upper part protrudes above the water surface, and the lower part of the outer periphery is fixed in the shape of a cone in the rock bed, and the lower outer circumference is formed with a ring mesh and separated into left and right sides, respectively. Left and right pair of scour prevention cylinders fixed in the state and the top and bottom open; A fastening ring surrounding the pair of left and right scour prevention cylinders on the outside; An air scrubbing tube filled with air or liquid therein and respectively positioned inside the scour prevention cylinder; The ruler is installed upright at the top, and the ball bearing is installed on the outer circumference to induce ascent and smoothness.The inwardly inclined surface is formed at the bottom to become thicker and is located at the upper part of the scour prevention tube. A self-weight body that presses the tube downward by its own weight; It relates to a scour prevention device and scour detection device is formed in the upper end of the hole through which the ruler of the self-weight body is formed and has a cover for sealing the top of the scour prevention cylinder.;The present invention, by installing a tube to fill the voids due to scour by the self-weight in the outer diameter portion of the well base of the pier, it is possible to prevent the lower part of the well base easily deformed even at a lower cost and equipment, By delaying the progress of the scour, the life of the bridge can be further extended.;Scour prevention body, scour prevention tube, self-weight, fastening ring, cover
