Abstract
本发明公开一种地表定点深孔分层注浆施工方法，包括：自施工区域地表向需要注浆区域的内部垂直钻孔，孔深设定为80～150米。成孔达到设计深度后，将第Ⅰ型袖阀管(100)下入钻孔的末端，再逐节连接第Ⅱ型袖阀管(200)下入钻孔的设计注浆段，然后逐节连接第Ⅲ型袖阀管(300)下入钻孔的非设计注浆段。袖阀管安设完成后，向袖阀管外壁和钻孔内壁之间的空隙注入套壳料进行封孔。封孔完成，待固结后，下入注浆芯管(600)。第一根注浆芯管(600)的末端穿过止浆塞(700)和止浆塞(700)连接，再将其余注浆芯管(600)逐节连接后下入到袖阀管内直至止浆塞(700)下入袖阀管的底部。连接注浆管路至芯管端，准备注浆液，通过注浆芯管(600)开始注浆作业。
The invention discloses a layered grouting construction method for fixed-point deep holes on the ground. After the hole is formed to the design depth, run the Type I sleeve valve tube (100) into the end of the drilled hole, and then connect the Type II sleeve valve tube (200) into the designed grouting section of the drilled hole section by section, and then section by section. Connect the non-design grouting section of the type III sleeve valve pipe (300) into the drilled hole. After the sleeve valve tube is installed, inject the casing material into the gap between the outer wall of the sleeve valve tube and the inner wall of the drilled hole to seal the hole. After the hole sealing is completed, the grouting core pipe ( 600 ) is lowered into after being consolidated. The end of the first grouting core pipe (600) is connected through the grouting stopper (700) and the grouting stopper (700), and then the remaining grouting core pipes (600) are connected section by section and then lowered into the sleeve valve tube until A stopper (700) runs into the bottom of the sleeve valve tube. Connect the grouting pipeline to the end of the core pipe, prepare the grouting liquid, and start the grouting operation through the grouting core pipe (600).
