Single pre-stressed anchor rod combined foundation reinforcement construction method
The invention mainly relates to the field of foundation reinforcement, in particular to a single pre-stressed anchor rod combined foundation reinforcement construction method. The method comprises the steps that A1, a site is leveled; a2, measuring and placing a grouting point position and an anchor rod pile position; a3, grouting construction; b1, anchor rod hole construction; b1.1, an anchor rod is manufactured, and a grouting pipe is installed; b2, mounting an anchor rod; b3, grouting the anchor rod hole; b4, anchor rod anti-corrosion and waterproof sealing; b5, prestress tensioning and locking; b6, anchor sealing; a traditional anti-floating anchor rod construction method is simplified, a single rod body is adopted, factory machining and on-site installation construction are conducted, application of rod body materials is reduced, on-site machining links are reduced, construction efficiency is improved, and the construction period is effectively shortened. And foundation soil grouting reinforcement is carried out in advance, so that the risk problems of hole collapse, hole stringing and the like caused by geological conditions are perfectly solved, and the one-time construction qualification rate of the anchor rod hole of the anchor rod pile is ensured. Foundation soil grouting reinforcement is carried out in advance, construction investment is reduced, and the construction period is shortened.
本发明主要涉及地基加固领域，具体的说是一种单根预应力锚杆结合地基加固施工方法。本方法包括:A1场地整平；A2注浆点位、锚杆桩位测放；A3注浆施工；B1锚杆孔施工；B1.1锚杆制作、注浆管安装；B2安装锚杆；B3锚杆孔注浆；B4锚杆防腐防水封闭；B5预应力张拉锁定；B6封锚；简化传统抗浮锚杆施工方法，采用单根杆体，工厂加工，现场安装施工，减少了杆体材料应用，减少了现场加工环节，提高了施工效率，有效缩短施工工期。通过提前进行地基土注浆加固，完美解决了因地质条件问题造成塌孔、串孔等风险问题，确保了锚杆桩锚杆孔一次施工合格率。提前进行地基土注浆加固，减少了施工投入，缩短施工周期。
