CONNECTION PIPE OF A CORRUGATE PIPE, WHICH PREVENTS THE SEPARATION OF A CORRUGATE PIPE BY EARTHQUAKE OR DIFFERENTIAL SETTLEMENT

摘要

PURPOSE: A connection pipe of a corrugate pipe is provided to prevent the separation of a corrugate pipe by earthquake or differential settlement by installing a wedge at a recessed part of a corrugate pipe. CONSTITUTION: A connection pipe of a corrugate pipe comprises a cylindrical socket(100). A stopping sill(110) is formed on the center of the inner circumference of the cylindrical socket body. Packings(300,300') are arranged in main parts(210,210') of the corrugate pipe. Both sides of the corrugate pipe are inserted into the cylindrical socket to reach the stopping sill. A circular corrugation(150) is densely formed on the inner circumference of the cylindrical socket body. Wedge holes(120,120') are formed on the circumference of the cylindrical socket body. Wedges are inserted into the wedge hole. The wedge is installed in the main part of the corrugate pipe.
