Two-time bolting and grouting integrated construction method for deep and shallow rock masses of inclined drift
The invention provides a twice bolting and grouting integrated construction method for deep and shallow rock masses of an inclined drift, and belongs to the technical field of inclined drift grouting. Comprising the following steps that S1, grouting and anchoring are conducted on a bottom plate, grouting and anchoring are integrally constructed, and secondary construction is conducted according to deep and shallow parts; s2, shallow rock mass construction: firstly drilling shallow holes by using a ZQJJ-200/1.8 pneumatic frame column type drilling machine, immediately lowering a grouting anchor rod after forming the holes, and constructing in rows at intervals, namely firstly drilling holes and lowering the grouting anchor rod according to the row spacing of 1000 * 3200mm, continuously constructing 10 rows, and then continuously performing grouting; and S3, deep rock mass construction. According to the construction method, grouting and anchoring are carried out on the bottom plate, grouting and anchoring integrated construction is carried out, deep and shallow secondary construction is carried out, front bolting and grouting integration is achieved through grouting anchor rods, deep bolting and grouting integration is achieved through solid anchor cables matched with grouting pipes, floor heaves do not occur any more, the side bottom does not move inwards any more, and therefore the requirement for operation of the overhead man-riding device is met; and the safety is improved.
本发明提供了一种斜巷深浅部岩体两次锚注一体化施工方法,属于斜巷注浆技术领域。包括以下步骤:S1.对底板实施注浆与锚固,使注浆与锚固一体化施工,且分深浅部二次施工;S2.浅部岩体施工:使用ZQJJ‑200/1.8气动架柱式钻机首先钻取浅孔,成孔后即刻下放注浆锚杆,每排4孔,间隔排施工,即先按照间排距1000*3200mm钻孔和下放注浆锚杆,连续施工10排,而后连续实施注浆;S3.深部岩体施工。本发明通过对底板实施注浆与锚固,注浆与锚固一体化施工,且分深浅部二次施工,前部锚注一体化用注浆锚杆实现,深部锚注一体化用实心锚索配套注浆管实现,使得底臌不再发生,帮底不再内移,从而满足架空乘人器运行的要求,增加了安全性。
