Cast-in-place method of concrete square pile

Abstract

The invention provides a cast-in-place method of a concrete square pile. The method comprises the following steps: forming a reinforcement cage through a welding mode, bending main reinforcements at four corners of the reinforcement cage to form pile tips, placing a steel plate on the pile tips, connecting through the welding mode to form a framework of the concrete square pile, and placing the framework in a concrete square pile mold; unloading the stirred concrete in a concrete pump truck through a concrete transport vehicle; guiding the concrete into a ground pump by the concrete pump truck; guiding the ground pump into the concrete square pile mold through a distribution rod; curing the concrete to form the concrete square pile; finally removing the concrete square pile mold. By using the concrete pump truck and the layout mode of the concrete pump truck, the concrete can be quickly transported into the concrete square pile mold from a concrete stirring part, so the concrete cast-in-place efficiency is improved, the proportion of the concrete and the reinforcement is accurately adjusted, and the strength of the concrete square pile is improved.

Description

technical field [0001] The invention relates to an in-situ casting method of concrete square piles. Background technique [0002] Concrete square piles are an important part of building foundations. They not only carry the superstructure, but also need to ensure the stability of the superstructure. In recent years, more concrete square piles have been used in various foundation projects, because concrete square piles are generally prefabricated in factories or cast on site. At present, the prefabricated concrete square piles in the factory are likely to cause the length of the single pile to be too long and the specifications are not uniform, resulting in high engineering cost and easy to pull out the reinforced concrete core, causing the concrete square pile to fall from the abutment, column, Beams are separated, which leads to engineering quality and safety accidents. And most of the concrete square piles in the prior art are completed by prefabrication, but the concrete...

Problems solved by technology

At present, the prefabricated concrete square piles in the factory are likely to cause the length of the single pile to be too long and the specifications are not uniform, resulting in high engineering cost and easy to pull out the reinforced concrete core, causing the concrete square pile to fall from the abutment, column, Separation of the beams, resulting in engineering quality and safety accidents

And most of the concrete square piles in the prior art are completed by prefabrication, but the concrete square pile mold structure is simple, the damage rate of the produced concrete square piles is high, the thickness of the concrete covering steel bars is uneven, and a large amount of materials are wasted
