High-pressure grouting device
The invention discloses a high-pressure grouting device. The high-pressure grouting device comprises a drill rod and a grouting pipe. The drill rod comprises a rod body, a drill bit fixed to the lower end of the rod body and a sleeving barrel fixed to the top face of the drill bit and located in the rod body, a guniting pipe is arranged on the periphery of the drill rod, a baffle used for blocking the guniting pipe is arranged on the inner periphery of the drill rod, a baffle pressure spring is connected with the sleeving barrel, a conveying pipe is arranged on the side face of the baffle, and an auxiliary guniting pipe is arranged on the periphery of the sleeving barrel. The auxiliary guniting pipe is connected with the conveying pipe; and the grouting pipe can be inserted into the rod body and is detachably connected with the sleeving cylinder through the locking plate. According to the high-pressure grouting device, the lower end of the rod body is sealed through the drill bit, the grouting pipe is connected through the sleeving barrel, the drill rod and the sleeving barrel are communicated through a pipeline, slurry conveying is achieved, it is guaranteed that the slurry is smoothly sprayed out, the phenomenon that the grouting pipe extends out of the rod body is avoided, direct contact between the grouting pipe and various materials in a drilled hole is avoided, and the grouting efficiency is improved. And the damage probability of the grouting pipe is effectively reduced.
本发明公开了一种高压注浆装置，所述高压注浆装置包括钻杆和注浆管；钻杆包括杆体、固定在杆体下端的钻头和固定在钻头顶面并位于杆体内的套接筒，钻杆的外周设有喷浆管，钻杆的内周设有用于封堵喷浆管的挡板，挡板压力弹簧连接套接筒，挡板的侧面设有输送管，套接筒的外周设有副喷浆管，副喷浆管连接输送管；注浆管能够插接至杆体内并通过锁紧板与套接筒可拆卸连接。所述高压注浆装置通过钻头封闭杆体的下端，通过套接筒连接注浆管，钻杆与套接筒之间通过管道连通并实现浆液的输送，保证浆液顺利喷出，避免了注浆管延伸至杆体外的现象，规避了注浆管与钻孔内各种物料的直接接触，有效降低了注浆管受损的概率。
