Pipe-jacking slurry with micro bearing capacity and preparation method thereof
The invention provides pipe-jacking slurry with micro bearing capacity and a preparation method thereof. The slurry comprises bentonite raw slurry, a slurrying agent and a high-molecular polymer, thebentonite raw slurry comprises bentonite and water, in each cubic meter of the bentonite raw slurry, the addition amount of the slurrying agent is 55-60 kg, and the addition amount of the high-molecular polymer is 3-3.5 L. The problems that in pipe jacking construction, existing antifriction slurry is easily diluted in a stratum with the high water content, an effective slurry sleeve cannot be formed on the periphery of a pipe jacking machine and the periphery of a pipe joint, the workload of repeated pressure injection is increased in construction, and the pipe jacking construction efficiencyis affected are solved.
本发明提供了一种具有微承载力的顶管泥浆及其制备方法，该泥浆包括：膨润土原浆、制浆剂以及高分子聚合物，所述膨润土原浆包括膨润土和水，在每立方米的所述膨润土原浆中，所述制浆剂的添加量为55kg～60kg，所述高分子聚合物的添加量为3L～3.5L。本发明解决了在顶管施工中，现有的减摩泥浆在含水量较高的地层中，易被稀释，无法在顶管机、管节周边形成有效的泥浆套，施工中增加重复压注的工作量，影响顶管施工工效的问题。
