Deep foundation pit anchor cable grouting construction method
The invention relates to the technical field of anchor cable construction, in particular to a deep foundation pit anchor cable grouting construction method. Comprising the following construction steps that drilling is conducted on a preset construction surface, the drilling surface is leveled and cleaned, after drilling is conducted, an anchor cable is placed into a hole, a grouting pipe is inserted, concrete is poured into the bottommost part in the hole, the concrete is waited to be solidified, tensile stress treatment is conducted on the anchor cable, and then concrete is integrally poured into the hole. And after the concrete in the hole is solidified, the anchor cable mounting fixing seat is fixed at the hole opening. The grouting pipe is directly inserted into the bottom of a hole, the grouting pipe is pulled out while grouting is conducted, the grouting uniformity is guaranteed, grouting solidification is conducted at the bottom firstly, foundation support is provided for conducting tensile stress treatment on the anchor cable, the fixing base is installed, anchor cable prestress shrinkage is reduced, and the tensile stress of the anchor cable to a building is improved.
本发明涉及锚索施工的技术领域,尤其是涉及一种深基坑锚索注浆施工方法。包括以下施工步骤,在预定施工表面进行打眼钻孔,对钻孔表面进行平整和清理,打眼钻孔后对将锚索放入孔内,插入注浆管,向孔内最底部进行灌注混凝土,等待混凝土凝固,对锚索进行拉应力处理,然后对孔内进行整体灌注混凝土,等待孔内混凝土凝固后,在孔口处对锚索安装固定座进行固定。将注浆管直接插入孔底,灌注的同时将注浆管拉出,保证灌注的均匀性,先在底部进行灌浆凝固,为对锚索进行拉应力处理提供基础支撑,安装固定座减少锚索预应力收缩,提高锚索对建筑的拉应力。
