Construction method of pebble bed anchor rod post-insertion method
The invention discloses a pebble bed anchor rod post-insertion construction method, and relates to the technical field of anchor rod construction. The pebble bed anchor rod post-insertion construction method comprises the steps that drilling and forming of a pebble bed are carried out, grouting is carried out through a drill rod, post-insertion of an anchor rod is carried out after grouting, a pile casing is not used in drilling and forming, the drill rod is not withdrawn after drilling and forming, and hole channel grouting is carried out through the drill rod. According to the pebble bed anchor rod post-insertion construction method, the difficulty that a hole cannot be formed can be avoided, the situation that the anchoring force is insufficient due to hole collapse is greatly reduced, construction is convenient, a pile casing is not used in construction, and the situation that part of the pile casing cannot be pulled out and is finally embedded into the hole, and consequently pile casing materials are wasted is also avoided. Construction is convenient and fast, and the purposes of saving time, labor, energy and materials are achieved while the requirement for the anchoring force of the anchor rod is met.
本发明公开了一种泥卵石层锚杆后插法施工方法，涉及锚杆施工技术领域。该泥卵石层锚杆后插法施工方法，包括泥卵石层钻孔成型、通过钻杆注浆、注浆后进行后插锚杆且在钻孔成型中不使用护筒，钻孔成型后不退出钻杆，并通过钻杆进行孔道注浆。该泥卵石层锚杆后插法施工方法可以避免无法成孔的困难，较大的减少了塌孔造成锚固力不足的情况，施工方便，且施工中不使用护筒，也避免了部分护筒无法拔出，最终埋入孔洞造成的护筒材料浪费情况。本发明施工方便快捷，能达到满足锚杆锚固力要求的同时，省时省工，节能节材目的。
