A bundle of pipes cable for concrete construction and construction method for grouting to the jointing portion of concrete structures by using the same

摘要

Concrete pipe bundle cable construction of the invention, which is yugonggwan plurality of exhaust holes perforated for the discharge of the injection material and grouting; That is wound in a spiral on the outer peripheral surface of yugonggwan, pipes for a plurality of shape retention to avoid the deformation of the inner circular section of the curve during the construction of yugonggwan yugonggwan; And wound spirally on the outer peripheral surface of the yugonggwan with a plurality of form-retaining tube for, by the authorized grouting pressure so that in cross section is reduced can be a grouting material injected by giving create a gap discharge after the recovery of the grouting pressures, is configured to end surface is in close contact with the outer wall of the form-retaining tube for as restitution includes a plurality of opening and closing a soft resin foam rods for blocking the reverse flow of grouting material, this joint grouting method using the same bundle of tubes cables in construction joint portion installing a concrete construction bundle tube cables, and the bundle of tubes ray caused by bleeding phenomenon by injecting a grouting material into the yugonggwan discharged through a plurality of discharge hole, which is drilled in the yugonggwan in the cable capacitance (white particles), the fine space of the portion a is filled with grouting material.; Thus, according as the present invention, is installed at the construction site easy and to charge the fine pores of the easily construction joints with grouting miniature pump, it is possible to improve construction quality even in a watertight construction of the concrete construction joints region.
