一、问题的提出采用预应力锚索锚固地下洞室、稳定岩土边坡、加固地基基础、处理坝体或混凝土结构裂缝等,在实际工程中常会遇到需将锚孔布置成水平或上仰的,以获得经济合理的锚固效果。特别是对于全长有粘结的、采用水泥注浆胶结式的内锚固段,为便于注浆,使内锚固段提供可靠的锚固力,需要设置一个把内锚固段与张拉段分隔开的装置(阻浆装置)。即使是对于下斜锚孔,应用阻浆装置,可以在加固孔壁周围岩层或土体压浆时,保持所需要
I. Proposals The use of prestressed anchor cables to anchor underground caverns, stabilize rock and soil slopes, reinforce foundation foundations, treat dams or cracks in concrete structures, etc., often encountered in practical projects require the anchor holes to be arranged horizontally or horizontally. Yang Yang, in order to obtain economic and reasonable anchoring effect. Especially for the integral anchorage section with cemented cement grouting type, it is necessary to provide an internal anchorage section separated from the tensioning section in order to facilitate grouting and provide a reliable anchorage force for the inner anchorage section. The device (resistance device). Even for the downwardly inclined anchor holes, applying a slurry resistance device can maintain the required strength when reinforcing rock formations or soil around the hole walls.
