Deformation directional grouting device and vacuum combined directional grouting foundation construction method
The invention provides a deformation directional grouting device and a vacuum combined directional grouting foundation construction method, and relates to the technical field of construction engineering construction.The deformation directional grouting device comprises a slurry pipeline, a protective sleeve and a cutting blade, the cutting blade is provided with a first connecting structure, and the outer surface of the slurry pipeline is provided with a second connecting structure; the first connecting structure and the second connecting structure are hinged through a connecting piece; the outer side of the slurry pipeline is sleeved with the protective sleeve, the protective sleeve is provided with a groove structure used for allowing the cutting blades to stretch out, a sliding clamping tenon is arranged in the protective sleeve, and sliding grooves matched with the sliding clamping tenon are formed in the outer sides of the cutting blades. The grouting treatment depth is deeper, the treatment effect is better, the speed is higher, the applicability is high, the slurry shape is basically controllable through the vacuum negative pressure drainage guiding effect, a large number of materials are saved, and the overall stability is improved.
本发明提供了一种变形定向注浆装置及真空联合定向注浆地基施工方法，涉及建设工程施工技术领域，包括浆液管道、保护套管以及切削叶片，切削叶片上设置第一连接结构，浆液管道的外表面设置第二连接结构，第一连接结构与第二连接结构通过连接件铰接连接；保护套管套设于浆液管道的外侧，保护套管上开设有用于切削叶片伸出的槽结构，保护套管的内部设置滑动卡榫，切削叶片的外侧设置有与滑动卡榫相配合的滑槽，本发明的有益效果是高压注浆与真空联合预压地基处理相结合，注浆处理深度更深且处理效果更好，速度更快适用性强，通过真空负压引流导向作用，浆体形状基本可控，节省大量材料，提高整体的稳定性。
