Curing agent for deep single-shaft sludge mixing pile and preparation method thereof
The invention discloses a curing agent for a deep single-shaft sludge stirring pile and a preparation method thereof, the provided curing agent comprises a powder component and a slurry component, according to different construction processes, the powder component is used for powder spraying process construction, and the powder component and the slurry component are jointly used for slurry spraying process construction. Wherein the powder component consists of a cementing material, an exciting agent and a dispersing agent; the slurry agent component is composed of a high-performance water reducing agent, a pumping lubricant, a defoaming agent, a reinforcing agent and water. The invention also provides a preparation method of the curing agent. The method has the advantages that the dispersion uniformity of the curing agent in sludge is improved, and the adhesion resistance to a stirring drill bit is reduced; according to the construction method, stable and uniform mixing of the curing agent in each layer of sludge is guaranteed, upward slurry returning is reduced, the smoothness and the later strength in the construction process are enhanced, the pile forming quality and the foundation reinforcing effect are improved from the curing material end, and the economical efficiency and the environmental protection property are greatly improved.
本发明公开了一种深层单轴淤泥搅拌桩用固化剂及其制备方法，提供的固化剂包括粉剂组份和浆剂组份，根据施工工艺不同，粉剂组份用于粉喷法工艺施工，粉剂组份和浆剂组份共同用于浆喷法工艺施工。其中，粉剂组份由胶凝材料、激发剂和分散剂组成；浆剂组份由高性能减水剂、泵送润滑剂、消泡剂、增强剂和水组成。本发明还提供了一种上述固化剂的制备方法。本发明的优点在于：提升固化剂在淤泥中的分散均匀性，降低对搅拌钻头的黏附阻力；保证了固化剂在每层淤泥中的稳定均匀掺入，减少向上返浆，并且也对施工过程中的流畅度和后期强度都有所增强，从固化材料端提升了成桩质量和地基加固效果，并在经济性和环保性上有较大提高。
