Steel slag pervious concrete pile and anti-blocking device and method of concrete pile

Abstract

The invention discloses a steel slag pervious concrete pile and an anti-blocking device and method of the concrete pile. The steel slag pervious concrete pile is made of a composite. The composite isprepared by matching following raw materials which comprise, by weight, 11-21 parts of cement, 72-82 parts of steel slag, 1-10 parts of a water reducing agent and 1-10 parts of water. The anti-blocking device of the concrete pile comprises a pile point and a geotechnical cloth net. The geotechnical cloth net can cover the outer side of the steel slag pervious concrete pile as described in claim 1,the pile point can be connected with a circular table portion of the bottom side of the steel slag pervious concrete pile as described in claim 1, and the lower portion of the geotechnical cloth netis connected with the top face of the pile point. Waste steel slag is effectively utilized, the bearing force of a pile body is enhanced, the performance of the pervious concrete pile mixed with the steel slag is superior to that of a common pervious concrete pile, the steel slag pervious concrete pile has good water permeability and expansibility, and by means of application of the anti-blockingdevice, the anti-blocking problem in the construction process of the previous pile is solved.

Description

Technical field [0001] The invention relates to the field of civil engineering, in particular to a steel slag permeable concrete pile, a concrete pile anti-clogging device and method. Background technique [0002] Steel slag is an industrial waste produced during steelmaking. my country’s steel output has reached 450 million tons, and the amount of steel slag produced is about 70 million tons. According to incomplete statistics, the utilization rate of steel slag in my country is less than 10%. A large amount of land is also the source of environmental pollution. Therefore, the development and utilization of steel slag as a secondary resource has always been an important content of research. [0003] The application of higher-strength steel slag as aggregate to the pile body is a research trend in civil engineering materials: the steel slag aggregate and the interface structure have a larger hermetic force, which affects the compressive strength and erosion resistance of the config...
