    摘要:

    我国地下水污染已呈现从点状污染向带状和面状污染发展的态势,传统修复材料投放工艺粗糙、在含水介质中难扩散,且地下水存在分层、赋存状态多变,注入参数控制难度大,易导致各层水交叉污染等问题。针对这些问题,本文提出了集垂直/导向钻进、旋转喷射注入、微压压裂扩散、扩张封隔等一体的原位喷射注入工艺,研制了配套钻进—注入一体化钻具,总结了喷射注入过程中修复材料的运移和修复机制,为污染场地原位修复系统的设计奠定基础,为绿色精准修复提供参考。

    Abstract:

    Groundwater contamination in China has developed from point-like to band-like and surface-like contamination. Traditional remediation materials are roughly placed, difficult to diffuse in the water-bearing media, and there are problems such as stratification of groundwater, variable storage states, difficulty in controlling injection parameters, and easy cross-contamination of various layers of water. To address these problems, this paper proposes an in-situ injection process that integrates vertical/guided drilling, rotary injection, micro-pressure fracture diffusion and expansion seal, develops an integrated drilling-injection tool, summarises the transport of remediation materials and remediation mechanisms during injection, lays the foundation for the design of in-situ remediation systems for contaminated sites, and provides a reference for green and precise remediation.
