Abstract

The invention relates to the technical field of mud hardening treatment of an empty pile section, and discloses a curing agent for mud hardening treatment of an empty pile section, a preparation method and a construction method. The curing agent includes an efficient structural agent and an admixture. The efficient structural agent and the admixture are blended with water to form curing slurry. The efficient structural agent is stirred, then the admixture is added and stirred, then water is added and the mixture is stirred to form the curing slurry, achieving preparation. Through multi-stage stirring, cured bodies and water are mixed more thoroughly; conveying compressed air and curing slurry to the empty pile section so that the curing slurry and waste mud are stirred and mixed, achievinghardening treatment. Through multi-stage stirring, components of the curing agent are mixed more thoroughly. By adoption of the curing agent, the hydration reaction degree is higher, the curing speedis higher, high-water-content mud in construction can be consumed rapidly, hidden safety risks caused by long-term stacking can be prevented, efficient resource utilization is achieved, and strengthof cured soil is higher and meets the bearing capacity of foundation soil.

Description

technical field [0001] The patent of the present invention relates to the technical field of mud hardening treatment of empty pile sections, specifically, a curing agent, a preparation method and a construction method for mud hardening treatment of empty pile sections. Background technique [0002] Bored cast-in-situ pile refers to the use of percussion drilling rigs according to geological conditions, mud retaining method to form holes, concrete is mixed centrally by mixing station, transported by concrete mixer truck, steel cage is processed and formed at one time, and a kind of foundation is poured into underwater concrete by conduit method. ;During construction, due to the existence of internal support in the foundation pit, the construction starts from the ground downward to avoid the rotary drilling rig touching the internal support. Therefore, after the concrete is poured, there will be a section from the ground to the top of the pile that does not need to be reinforce...
