1固结灌浆设计1．1灌浆目的为改善进水塔地基岩石的力学强度和变形模量,增强基岩的整体性,补强在结构开挖中形成的基岩损伤,设计要求对进水塔基础做固结灌浆处理。1．2灌浆孔布设形式、孔排距及孔深(1)灌浆孔的布置采用方格形,3个次序,孔排距均为3m。断层带两侧以及灌浆后单位吸水率＜3Lu的地区,其孔位、孔距,可根据现场地质情况,做适当调整或加密。
1 Consolidation Grouting Design 1.1 Grouting Purpose In order to improve the mechanical strength and modulus of deformation of infill tower foundation rock, enhance the integrity of bedrock, and reinforce the bedrock damage caused by structural excavation, the design requirements for influent Tower foundation consolidation grouting. 1.2 Grouting hole layout, hole row spacing and hole depth (1) Grouting hole layout with square shape, three orders, row spacing are 3m. Both sides of the fault zone and grouting unit water absorption <3Lu area, the hole, hole distance, according to the site geological conditions, make appropriate adjustments or encryption.
