Cage core capsule anchor rod integrated grouting device, cage core capsule anchor rod and construction method
The invention relates to the technical field of foundation rock anchor rod construction, and provides a cage core and capsule anchor rod integrated grouting device, a cage core and capsule anchor rod and a construction method. The air exhausting and slurry discharging integrated assembly comprises a slurry discharging pipe; the cover plate is used for closing or opening the slurry outlet; the elastic damping piece is connected with the grout outlet pipe and the cover plate and used for providing damping force for the cover plate to open the grout outlet; the top end of the exhaust pipe is provided with an exhaust port, and the bottom end is closed; the buoyancy ball is movably arranged in the exhaust pipe and used for closing or opening the exhaust port; the density of the buoyancy ball is larger than that of water and smaller than that of cement paste injected into the bag through the grouting pipe. Compared with traditional secondary grouting, only one-time grouting operation is needed, the working procedure is simple, construction is convenient and fast, the construction difficulty is reduced, especially self-compaction is achieved through grouting in the bag, and the grouting effect in the bag and the anchor rod construction quality are improved.
本申请涉及基础岩石锚杆施工技术领域，提供一种笼芯囊锚杆一体化注浆装置、笼芯囊锚杆及施工方法，一体化注浆装置包括囊袋、注浆管以及排气出浆一体化组件；排气出浆一体化组件包括：出浆管；盖板，用于封闭或开启出浆口；弹性阻尼件，连接出浆管和盖板，用于为盖板开启出浆口提供阻尼力；排气管，顶端设置有排气口，底端封闭；浮力球，活动设置在排气管内，用于封闭或开启排气口；浮力球的密度大于水的密度，且小于通过注浆管注入囊袋内的水泥浆体的密度。相比于传统的二次注浆而言，只需进行一次注浆操作，工序简单，施工便捷，降低了施工难度，尤其是囊袋内注浆实现了自密实，提高了囊袋内注浆效果以及锚杆施工质量。
