Lock catch steel pipe pile water stop flexible plugging material and preparation method and application thereof
The invention belongs to the technical field of building materials, and discloses a lock catch steel pipe pile water stop flexible plugging material, which comprises the following components by weight: 40-50% of bentonite, 0.08-0.10% of a polymerizing agent, 9.0-15.0% of slag, 0.81-1.35% of an alkali activator, and 40.09-43.57% of an aggregate. The preparation method comprises the following steps: weighing the bentonite and the polymerizing agent in percentage by weight, adding the bentonite and the polymerizing agent into a stirrer, stirring at a medium speed for 1.5-2.5 minutes, then adding water which is 2% of the weight of the bentonite, continuously stirring for 3 minutes to form a mixture with uniform mass, standing for 2 hours, then adding the slag, the alkaline exciting agent and the aggregate into the mixture in percentage by weight, stirring at a medium speed for 2 minutes, and finally adding the aggregate into the mixture to obtain a finished product. And then adding water with the total mass ratio of 1: 1, and continuously stirring for 10 minutes to form the flow-state flexible plugging slurry. The buckling steel pipe pile water stop flexible plugging material prepared by the invention has the characteristics of no dispersion and underwater aggregation, and has good flowability and relatively small viscosity, so that gaps are better plugged, and the purpose of effective water stop is achieved.
本发明属于建筑材料技术领域，公开了一种锁扣钢管桩止水柔性封堵材料，按重量百分比包括以下组分：膨润土40‑50％，聚合剂0.08‑0.10％，矿渣9.0‑15.0％，碱性激发剂0.81‑1.35％，骨料40.09‑43.57％。制备方法包括：先按重量百分比称取膨润土和聚合剂加入搅拌器中，中速搅拌1.5‑2.5min，然后加入膨润土重量的2％的水，继续搅拌3min，形成质量均匀的拌合物并静置2h，接着按重量百分比将矿渣、碱性激发剂和骨料加入拌合物中，中速搅拌2min，随后加入总质量比1:1的水，继续搅拌10min形成流态柔性封堵料浆。本发明制备的扣钢管桩止水柔性封堵材料具有不分散且水下聚集的特点，具有良好的流动性以及较小的粘性，从而更好地封堵缝隙，达到有效止水的目的。
