Novel high-pressure jet grouting pile drill pipe system
The novel high-pressure jet grouting pile drill rod system comprises a drill bit, an air hammer pump, a slurry spraying pipe, a connector, a drill rod and a slurry inlet head which are coaxially and sequentially detachably connected, and a first inner pipe, a second inner pipe, a third inner pipe and a fourth inner pipe which are coaxially arranged are formed in the slurry spraying pipe, the connector, the drill rod and the slurry inlet head correspondingly; a first air channel, a second air channel, a third air channel and a fourth air channel are respectively formed between the slurry spraying pipe and the first inner pipe, between the connector and the second inner pipe, between the drill rod and the third inner pipe, and between the slurry inlet head and the fourth inner pipe; a guniting nozzle communicating with the interior of the first inner pipe is formed in one side of the guniting pipe. According to the invention, the integration of drilling and grouting is realized, the grouting operation can be realized while drilling, and the sequence of drilling and grouting is operated according to the actual situation.
本申请公开了一种新型高压旋喷桩钻杆系统，包括同轴依次可拆卸连接的钻头、气锤泵、喷浆管、连接器、钻杆、进浆头部，所述喷浆管、连接器、钻杆、进浆头部的内部分别形成有同轴设置的第一内管、第二内管、第三内管、第四内管，所述喷浆管与第一内管之间、所述连接器与第二内管之间、所述钻杆与第三内管之间、所述进浆头部与第四内管之间分别形成有第一空气通道、第二空气通道、第三空气通道、第四空气通道，所述喷浆管的一侧形成有连通所述第一内管内部的喷浆嘴。本发明实现了钻与灌的合一，在钻的同时可以实现灌浆操作，根据实际情况来操作钻与灌的顺序。
