Pile-type adjustable draught fan sinking-reducing pile side circulating grouting reinforcement device and pile-type adjustable draught fan sinking-reducing pile side circulating grouting reinforcement method
The invention relates to the technical field of pile foundation construction, and discloses a pile-type adjustable fan sinking-reducing pile side circulating grouting reinforcement device and method.The pile-type adjustable fan sinking-reducing pile side circulating grouting reinforcement device comprises a plurality of grouting floral tubes, the grouting floral tubes are vertically and evenly distributed on the peripheral side of a cast-in-place pile, and floral tube grouting holes are formed in the grouting floral tubes; a grouting core pipe is arranged in each grouting floral pipe, the top end of each grouting core pipe is used for being connected with a grouting machine through a grouting hose, core pipe grouting holes are further formed in the grouting core pipes and correspond to the floral pipe grouting holes, and grouting plugs are arranged at the ends of the grouting core pipes for sealing. According to the method, the situation that a fan foundation needs to be subjected to multiple times of jacking deviation rectification, after the pile type adjustable fan is subjected to jacking deviation rectification, settlement occurs to a settlement reduction pile, the bearing capacity of the pile and the side friction resistance of the pile are reduced is considered, a grouting floral tube and a grouting core tube are arranged, a burr-shaped cement column is formed through high-pressure grouting, a pile side soil body is split, the pile side soil body is further reinforced, and the side friction resistance is increased; and multiple times of circulating grouting can be achieved.
本发明涉及桩基施工技术领域，公开了一种桩式可调风机减沉桩侧循环注浆加固装置及方法，包括若干注浆花管，注浆花管竖向均匀分布在灌注桩周侧，注浆花管上设有花管注浆孔；每一注浆花管内设有注浆芯管，注浆芯管顶端用于通过注浆软管连接注浆机，注浆芯管上还设有芯管注浆孔，芯管注浆孔与花管注浆孔对应设置，注浆芯管端部设有灌浆塞进行密封；本发明考虑了风机基础需要多次顶升纠偏，在桩式可调风机在顶升纠偏后，减沉桩出现沉降，桩的承载力和桩侧摩阻力减小，通过设置注浆花管和注浆芯管，利用高压注浆形成毛刺状水泥柱，劈裂桩侧土体，进一步加固桩侧土体，增加侧摩阻力；并且本发明可以实现多次循环注浆。
