Problems solved by technology

[0003] In the actual use of pipe piles, because pipe piles are often buried deep in the ground, the wet environment requires pipe piles to achieve a certain impermeability strength, but the existing pipe piles do not have it; in addition, in winter, due to Influenced by the cold environment, some pipe piles are not resistant to freezing, and cracks will occur, which will seriously affect the structural strength and service life of the pipe piles

Abstract

The invention relates to a frost-resistant and impermeable concrete pipe pile. The concrete pipe pile is mainly prepared from the following components in parts by mass: 50-60 parts of sodium silicate cement, 20-30 parts of finely ground sand, 10-20 parts of fly ash, 10-15 parts of tailings sand, 2-8 parts of lithium slag powder, 5-7 parts of activated carbon, 10-15 parts of natural gravel, 4-6 parts of polycarboxylate superplasticizer and air-entraining Dose 5‑7 parts. The invention has the advantages that: the concrete pipe pile of the invention has a reasonable distribution ratio of components, thereby improving the structural strength and service life of the concrete pipe pile.

Description

technical field [0001] The invention relates to the technical field of pipe pile manufacturing, in particular to a frost-resistant and impermeable concrete pipe pile. Background technique [0002] As we all know, concrete pipe piles are widely used in people's daily life, such as bridge piers, foundations of houses, foundations of buildings, etc. The role played by pipe piles cannot be replaced by other objects. [0003] In the actual use of pipe piles, because pipe piles are often buried deep in the ground, the wet environment requires pipe piles to achieve a certain anti-seepage strength, but the existing pipe piles do not have it; in addition, in winter, due to Due to the influence of cold environment, some pipe piles are not resistant to freezing, and cracks will occur, which will seriously affect the structural strength and service life of pipe piles. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a frost-...
