Abstract

The invention relates to a production method of a prestressed concrete corrugated sheet pile. The method is characterized by including: preparing concrete mixture; producing reinforcement cages; die-filling; prestress tensioning; concrete pouring and vibration forming; prestress tension releasing and die removing; conveying the overall die to an assembling pedestal, using a special automatic opening-closing device to open the lateral die so as to take out a finished sheet pile, cleaning the dies, apply demolding agent, and turning to the next production procedure; examining and putting into storage. The production method is high in production efficiency and low in energy consumption, work environments are improved, labor intensity of workers is lowered, and the products are stable in quality, high in safety coefficient and good in mechanical performance.

Description

technical field [0001] The invention relates to a novel construction material for building enclosure structures such as soil retaining, slope protection and cofferdam in the field of civil engineering, in particular to a prestressed concrete corrugated sheet pile. Background technique [0002] At present, in the field of civil engineering, there are many forms of building materials for building envelope structures. Commonly used temporary retaining structures, slope protection, cofferdams and other supporting structures include: steel sheet piles, rail piles, H-shaped steel piles, and three-axis cement mixing piles. Diaphragm wall (SMW construction method pile), rotary grouting pile, diaphragm wall, flat pile, pre-base pile and other construction methods or wood sheet piles, etc.; permanent retaining support structures include: cast-in-place underground diaphragm wall, gravity reinforced concrete retaining Walls, cast-in-situ bored piles, prefabricated U-shaped concrete shee...
