Adhesion resisting handling method for burrs adhered to inner wall of pipe die for concrete tubular pile

Abstract

The invention provides an adhesion resisting handling method for burrs adhered to the inner wall of a pipe die for a concrete tubular pile. The method comprises the steps that step 10, whether the pipe die has burrs is examined before pipe pile preparation; step 20, after the pipe die is adopted to prepare the pipe pile, the pipe die with burrs is placed into a steam maintenance pool for low-temperature maintenance: if the thickness of the burrs of the pipe die is less than 2.5 mm, the maintenance temperature is controlled to be under the natural temperature and no less than minus 5 DEG C, and the maintenance time is controlled to be in the range of 20-44 hours; if the thickness of the burrs of the pipe die is more than 2.5 mm, the maintenance temperature is controlled to be in the range of 25-35 DEG C, and the maintenance time is controlled to be 30 minus and plus 2 hours. According to the adhesion resisting handling method, the relationship between the concrete setting time and temperature is utilized, the burrs of the pipe die is re-adsorbed to the surface of the pipe pile under the control state, so that the burrs can fall off easily and can be disposed radically, and the cost minimization is realized.

Description

technical field [0001] The invention relates to a treatment method for reverse pasting of adherents on the inner wall of a concrete pipe pile pipe mold after sticking to the mold. Background technique [0002] In the production process of concrete pipe piles, pipe pile sticking is a common problem. The national standard GB13476-2009 of "Pretensioned Prestressed Concrete Pipe Pile" lists the pipe pile sticking first in the appearance inspection items. It is self-evident to improve the appearance quality of pipe pile products by properly dealing with the problem of sticking to the inner wall of the pipe mold. [0003] Usually, after the pipe pile is glued to the skin, the treatment method for the sticky mold is to use beating, shoveling, and grinding to force the pipe mold adhesion to leave the pipe mold, so that the pipe mold can be put into use, and the cost of labor and materials will increase, and the pipe mold will be damaged. The inner wall of the mold is mottled, uneve...
