Vertical type vibratory molding process for concrete tube of lining type prestressed steel cylinder

Abstract

The invention relates to a vertical type vibratory molding process for a concrete tube of a lining type prestressed steel cylinder, which is used for molding a tube core of the concrete tube of the lining type prestressed steel cylinder; a vertical type mould is utilized for pouring and vibratory molding; the vertical type mould consists of a bottom mould, a cylindrical core mould and a top mould; the bottom mould and the top mould are respectively and correspondingly provided with a clamp table of the core mould and a clamp ring of the core mould; the core mould is assembled on the clamp table of the core mould and the clamp ring of the core mould; the top mould at the outer side of the clamp ring of the core mould is provided with a clamp ring of a faucet of the steel cylinder; a baiting port is arranged between the clamp ring of the core mould and the clamp ring of the faucet; and a vibrator is fixed on the inner wall of the core mould. The vertical type vibratory molding process can realize the mechanical feeding, vibratory molding, small labor intensity and high production efficiency.

Description

technical field [0001] The invention relates to a vertical vibration forming process of a prestressed steel cylinder concrete pipe, which is used for forming a liner type prestressed steel cylinder concrete pipe core. Background technique [0002] In the manufacturing process of the lined prestressed steel cylinder concrete pipe (referred to as PCCPL pipe), it is necessary to make lining concrete on the inner wall of the steel cylinder to form a concrete pipe core, so a mold for concrete pipe core molding is required in the production. The present lined prestressed steel tube concrete tube core forming mold is a horizontal centrifugal mold. The method is to put the steel cylinder into the centrifugal pipe mold and fix it, then put the assembled steel cylinder centrifugal pipe mold on a horizontal centrifuge to rotate at high speed, and manually use a shovel to continuously put the pre-mixed concrete material into the high-speed rotating pipe mold In the steel cylinder, rely...
