Application method of stone chips in concrete pipe pile prefabrication

Abstract

The invention discloses an application method of stone chips in concrete pipe pile prefabrication. The application method comprises the steps that stone is subjected to primary crushing through a crusher, the particle diameter of the crushed stone chips is 5cm-15 cm, the stone chips subjected to primary crushing are subjected to secondary crushing, the diameter of the stone chips subjected to secondary crushing is 1cm-3 cm, the stone chips subjected to secondary crushing are subjected to tertiary crushing, and the diameter of the crushed stone chips is 1mm-3 mm; the stone chips subjected to tertiary crushing are conveyed to a concrete mixer through a conveying belt to be mixed with cement and water, and concrete mortar obtained after mixing is output to a pipe pile for prefabrication through a material conveying device. The stone chips are crushed into the gravel grade to be applied to prefabrication of the concrete pipe pile, the situation that gravel resources are insufficient is avoided, stone resources are widely distributed and convenient to use, on the one hand, cost is reduced, and on the other hand, the gravel resources are also prevented from being insufficient; and therefore the requirement for sustainable development of the prefabrication of the concrete pipe pile is met.

Description

technical field [0001] The invention relates to an application method of pipe piles, in particular to an application method of stone chips in the prefabrication of concrete pipe piles. Background technique [0002] With the development of reform and opening up and economic construction, pretensioned prestressed concrete pipe piles began to be widely used in railway systems, and expanded to industrial and civil buildings, municipal, metallurgy, ports, highways and other fields. In the Yangtze River Delta and Pearl River Delta regions, due to the geological conditions suitable for the use of pipe piles, the demand for pipe piles has increased sharply, thus rapidly forming a new industry. According to incomplete statistics, by the end of 2007, there were more than 400 pipe pile manufacturers in the country (excluding manufacturers in Taiwan), producing about 250 million meters of various pipe piles, with an output value of more than 30 billion yuan. At the same time, the annua...
