Detachable tooth shape, different diameter tooth shape pile die

Abstract

A die for a dismountable tooth-shaped pile and a different diameter tooth-shaped pile is provided with two strip-typed semi-circular smooth pipe dies that can be connected together by a fastener. The pile die of the invention is characterized in that each smooth pile die is provided with a mould core that is pressed and manufactured by a steel plate and is matched with the shape of an inner wall of the die; the inner wall of the mould core is provided with annular concave teeth at intervals of 150 to 750mm; one mould can be multi-functional without being processed into a novel die; therefore, the expansive cost for manufacturing the dies of the tooth-shaped pile and the different diameter tooth-shaped pile is reduced to the lowest; simultaneously a large amount of steel material are saved for the country; besides, huge working load during the transportation is reduced and the transportation cost is reduced, thus being beneficial to popularizing the tooth-shaped pile and the different diameter tooth-shaped pile in the whole country.

Description

Detachable tooth-shaped and different-diameter tooth-shaped pile molds technical field The invention relates to a mold for producing prestressed piles, in particular to a detachable mould for tooth-shaped and different-diameter tooth-shaped piles. Background technique With the continuous innovation of technology, the forms of prestressed pipe piles, in addition to smooth pipe piles, have successively appeared bamboo piles, tooth surface drainage pipe piles with sand lining, etc. These new piles are characterized by remarkable bearing capacity. Improvement, indirect energy saving, consumption reduction, and emission reduction effects are very objective, and should be vigorously promoted, but this kind of mold processing cost is very high, for example: a mold factory processes a bamboo pile mold with a length of 12.4 meters and a diameter of less than 400mm It needs more than 90,000 yuan and the production time is long and the process is complicated.
