Curing agent for curing bentonite slurry and construction method thereof
The invention relates to the technical field of pile foundation construction, and discloses a curing agent for curing bentonite slurry and a construction method thereof, and the curing agent comprises the following main cost components: cement clinker 10-30:quick lime 8-15:superfine slag powder 25-35:fly ash 12-25:desulfurized gypsum 5-15:sodium bicarbonate 0.8-1.5:lignosulfonate 1-2:an accelerator 1-5. The curing agent with the raw material component ratio is low in mixing amount in practical application when being mixed with bentonite slurry, the mixing amount is 15-25% of the weight of the bentonite slurry, the using amount of the curing agent is saved, and the compressive strength is 0.8 Mpa or above. The construction method adopted according to the raw material ratio comprises the following steps: S1, stirring the powdery curing agent according to the parameter conditions of the pile hole and the bentonite slurry; S2, connecting and debugging the air compressor and the injection machine; S3, adding a powdery curing agent into the injection machine and injecting the powdery curing agent into the pile hole; and S4, maintaining the solidified bentonite slurry in the pile hole. By means of the optimized curing agent and the construction method, financial resources, material resources and time cost are saved, and potential safety hazards caused by left pile holes are avoided.
本发明涉及桩基础施工技术领域，公开了用于膨润土泥浆固化的固化剂及其施工方法，所述固化剂主要成本成分包括水泥熟料10‑30:生石灰8‑15:矿渣微粉25‑35:粉煤灰12‑25:脱硫石膏5‑15:碳酸氢钠0.8‑1.5:木质磺酸盐1‑2:速凝剂1‑5。上述原料组分配比的固化剂，与膨润土泥浆混合实际应用中掺量少，为与膨润土泥浆重量的15～25％，节省固化剂用量，抗压强度为0.8Mpa以上。根据原料配比采用的施工方法是：S1、根据桩孔和膨润土泥浆的参数情况进行搅拌粉态固化剂；S2、对空压机和喷射机进行连接调试；S3、往喷射机中加入粉态的固化剂并往桩孔中喷射；S4、对桩孔中固化后的膨润土泥浆进行养护。通过优化的固化剂和施工方法，节省财力、物力及时间成本，避免遗留桩孔形成安全隐患。
