Novel synchronous grouting material capable of adjusting initial setting time and preparation method thereof
The invention discloses a novel synchronous grouting material capable of adjusting initial setting time and a preparation method of the novel synchronous grouting material. The novel synchronous grouting material is prepared by mixing the following components in parts by weight: 1650-1700 parts of matrix slurry, 13-26 parts of an early strength agent and 1.1-2.2 parts of a thickening agent, the early strength agent is prepared by mixing the following components in parts by weight: 0.08-0.12 part of triethanolamine, 2.5-5.6 parts of calcium chloride and the balance of water glass. The initial setting time of the slurry can be shortened, the early strength of the slurry can be improved, meanwhile, the later strength of the slurry can be effectively guaranteed, then the purposes of controlling pipe piece floating and stratum settlement are achieved, and the construction quality is guaranteed.
本发明公开了一种可调整初凝时间的同步注浆新型材料及其制备方法，同步注浆新型材料是由以下组分按重量份配比混合而成：基体浆液1650‑1700份，早强剂13‑26份，增稠剂1.1‑2.2份；早强剂是由以下组分按重量份配比混合而成：三乙醇胺0.08‑0.12份，氯化钙2.5‑5.6份，其余为水玻璃。本发明不仅可以缩短浆液的初凝时间、提高其早期强度，同时还能有效保证浆液的后期强度，进而达到控制管片上浮和地层沉降的目的，保证施工质量。
