Auxiliary blasting construction technology in rotary drilling hole used for rock-socketed pile foundation
The invention provides an auxiliary blasting construction technology in a rotary drilling hole used for a rock-socketed pile foundation, and relates to the technical field of building construction. The auxiliary blasting construction technology in the rotary drilling hole used for the rock-socketed pile foundation comprises the following steps that S1, construction preparation is conducted, specifically, firstly, a pile pier working platform is dug in a construction site, and then main construction equipment is prepared; S2, hole site arrangement is conducted, specifically, drilling is carriedout at the pile pier by using a down-the-hole drill, 12 drilled holes are formed in the pile diameter of 2.2 m, 9 drilled holes are formed in the pile diameter of 2.0 m; and S3, explosive filling isconducted, specifically, after drilling is completed, explosive filling is conducted, specifically, 2 # rock emulsion explosive is adopted as the explosive, a millisecond tube is adopted as a detonator to be installed in two sections, the detonator and the explosive and the explosive and the explosive are bound firmly by adopting adhesive tape, and scratching damage during explosive filling is prevented. By using the auxiliary blasting construction technology in the rotary drilling hole used for the rock-socketed pile foundation, the working procedure time can be greatly shortened, the construction expenditure is reduced, and meanwhile potential quality safety hazards caused by manual hole digging are effectively avoided.
本发明提供一种用于嵌岩桩基的旋挖钻孔内辅助爆破施工技术，涉及建筑施工技术领域。该用于嵌岩桩基的旋挖钻孔内辅助爆破施工技术，包括以下步骤：S1.施工准备，首先在施工地点挖好桩墩工作平台，然后准备好主要施工设备；S2.孔位布置，使用潜孔钻机在桩墩处进行开孔，桩径桩径2.2米设置钻孔12孔，桩径2.0米设置9孔；S3.装填炸药，钻孔完成后，装填炸药，炸药采用2#岩石乳化炸药，雷管使用毫秒管分两段位安装，雷管与炸药以及炸药之间采用胶带捆绑牢固，防止填炸药时剐蹭损坏。通过该用于嵌岩桩基的旋挖钻孔内辅助爆破施工技术的使用，可以大大缩短工序时间、减少施工经费，同时有效的避免的人工挖孔所带来的质量安全隐患。
