Novel compaction grouting soil nail and pull-out test device thereof
The invention belongs to the technical fields of civil engineering and geotechnical testing, and provides a novel compaction grouting soil nail and a pull-out test device thereof. The novel compactiongrouting soil nail is expanded by injecting cement slurry into special latex balls into to achieve compaction anchoring with a surrounding soil body. The pull-out test device comprises the novel compaction grouting soil nail, a test box, a grouting pressurization system, a pulling system, a measurement system and a data acquisition system and can be used for pulling tests of the novel compactiongrouting soil nail. The novel compaction grouting soil nail and the pull-out test device thereof have the beneficial effects that the novel compaction grouting soil nail can effectively avoid bleeding, penetration grouting or split grouting in the surrounding soil body; and the pull-out test device can be used for simulating compaction grouting processes under different saturation conditions and exploring the shear strength of a soil-nail interface and the response of the surrounding soil body to provide a basis for the design and safety assessment of the novel compaction grouting soil nail.
本申请属于土木工程、土工试验技术领域，提供一种新型压密注浆土钉及其拉拔试验装置。包括新型压密注浆土钉和拉拔试验装置。其中，新型压密注浆土钉通过将水泥浆液注入一种特殊的乳胶球使其膨胀，实现与周围土体的压密锚固；拉拔试验装置包括新型压密注浆土钉、试验箱、注浆加压系统、拉拔系统、量测系统以及数据采集系统，可用于新型压密注浆土钉的拉拔试验。本申请提供的方案，其有益效果在于：新型压密注浆土钉可有效避免周围土体发生泌水现象、渗透注浆或劈裂注浆；拉拔试验装置可用于模拟不同饱和度条件下压密注浆过程，探求土‑钉界面的抗剪强度和周围土体响应，为新型压密注浆土钉的设计和安全评估提供依据。
