摘要
灌注桩后注浆施工技术可在各类钻、挖、冲孔灌注桩及地下连续墙的沉渣、泥皮和桩底、桩侧一定范围土体的加固工程中应用,通过预先放置在桩内的导管注入水浆和泥浆的混合物,从而加固桩端与桩侧的沉渣,提高桩基的承载性能。灌注桩后注浆技术提高了桩基础的承受能力,降低了后期沉降量,也降低了施工成本,是值得推广应用的一项技术。
Post-grouting construction technology can be applied in various types of drilling,digging,punching and pouring piles and sediments of underground continuous wall,mud and pile bottom,and reinforcement of a certain range of soil on the pile side.Put The conduit placed in the pile injects a mixture of slurry and mud to reinforce the sediment at the pile end and the pile side and improve the bearing capacity of the pile foundation.Post-grouting technology improves the bearing capacity of the pile foundation,reduces the settlement at the later stage,and reduces the construction cost.It is a technology worthy of popularization and application.
