Problems solved by technology

As we all know, the higher the concrete strength, the greater the brittleness of the concrete, and the poorer the impact resistance. Moreover, most of the PHC pipe piles are still driven by diesel hammers at this stage. In the prior art, this The contradiction is still difficult to resolve

Abstract

The invention discloses a concrete formula for a high-strength tubular pile and a mixing and curing process thereof. The formula comprises 380-430 kg/m <3> of cement, 80-150 kg/m <3 > of a mineral admixture, 1100-1300 kg/m <3> of coarse aggregate, 400-500 kg/m <3> of fine aggregate, 6-8 kg/m <3> of a water reducing agent and 1-2 kg/m <3> of polyethylene particles or polystyrene particles, and the polyethylene particles or polystyrene particles contain reinforced fibers. According to the concrete formula for the high-strength tubular pile and the mixing and curing process of the concrete formula, the sand consumption and the water consumption can be reduced, meanwhile, the concrete has good flowability, the strength and the toughness of the tubular pile are improved, and meanwhile, the pore defects in the tubular pile are reduced.

Description

Technical field [0001] The present invention belongs to the field of building materials, and concrete formulations for high-strength pipe piles and their mixing and conservation process. Background technique [0002] Pipe piles have an important role in construction construction, and the pipe pile is divided into post-regulatory prestressed pipe piles and prestressed prestressed piles, prestressed concrete pipe pile (PC pipe pile) and prestressed concrete thin-walled pile ( PTC pipe pile) and high-intensity prestressed concrete pipe pile (PHC pipe pile). The prestressed concrete pipe pile can be divided into post-diamond prestressed piles and pretty prestressed piles. Pre-first prestressed pipe pile is a hollow cylinder elongated concrete prefabricated component made by the prestressed process and centrifugal formation method, which is mainly composed of cylindrical piles, end plates and steel ferrules. The pipe pile is mainly subject to axial stress during hitting or static pres...
