Construction method of a red mud fly ash geopolymer pile with a heatable pile body

Abstract

The invention discloses a construction method of a red mud fly ash geological polymer pile whose pile body can be heated. It includes the following steps: (1) Conduct indoor pile material ratio test according to the pile construction technology; (2) Drilling; select the drilling process according to the design size of the pile body and ground conditions; (3) Fabricate the heating device for the pile body; (4) ) pouring pile materials; (5) placing heating devices; (6) heating the pile body; (7) natural curing until the predetermined age, taking cores from the pile body, and testing the strength of the RFP pile body. The present invention aims at piles with red mud-fly ash (RFP) piles. By placing a heating device on the pile body, the on-site heating of RFP piles is realized, and the strength of red mud fly ash geopolymers is rapidly generated, effectively ensuring RFP pile quality. The invention can consume a large amount of red mud, provides a feasible method for the construction of red mud fly ash geological polymer piles, and provides a new idea for resource utilization of red mud.

Description

technical field [0001] The invention relates to a construction method of a construction pile, in particular to a construction method of a red mud fly ash geological polymer pile whose pile body can be heated, and belongs to the technical fields of waste comprehensive utilization and civil engineering. Background technique [0002] Red mud is a reddish-brown powder mud-like water-containing strong alkaline solid waste produced in the process of preparing alumina. For every 1 ton of alumina produced, 0.8-1.5 tons of dry red mud will be produced at the same time. At present, according to incomplete statistics, the comprehensive utilization rate of red mud in my country is very low, only 4%, and the accumulated reserves have reached hundreds of millions of tons. At present, a large amount of red mud mainly relies on large-area storage yards, which takes up a lot of land and causes serious pollution to the environment. It is imperative to minimize the harm of red mud and realize...
