Problems solved by technology

In order to improve the durability and bearing capacity of concrete pipe piles, most of the traditional concrete pipe piles increase their load resistance and impermeability by increasing the amount of steel and increasing the thickness of pipe piles. The technology of salt, acid-base substances, etc. has bee

Abstract

An anti-bacterial and anti-corrosion building pipe pile is characterized by being prepared from materials in parts by mass as follows: 10-15 parts of cement, 15-20 parts of sand, 30-45 parts of gravel, 5-8 parts of water, 0.5-1 part of a polycarboxylate superplasticizer, 3-5 parts of an anti-bacterial agent and 5-10 parts of nickel and steel alloy fibers with the diameter ranging from 0.2 mm to 0.3 mm and the length ranging from 10 mm to 20 mm.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antibacterial and anticorrosion construction pipe pile. Background technique [0002] It has been more than 20 years since my country's first pipe pile production line was introduced in 1987. With the continuous progress of science and technology and production technology, the varieties and specifications of pipe piles produced have become more abundant. The types of pipe piles currently produced include: prestressed concrete pipe piles (PC piles), prestressed high-strength concrete pipe piles (PHC piles) and prestressed concrete thin-walled pipe piles (PTC piles). Prestressed high-strength concrete pipe piles are widely used for their good pile material quality, high strength, driving resistance, strong penetration ability, strong adaptability to engineering geology, wide range of design options, easy pile deployment, economical and fast, and convenient testing. ...
