Anti-erosion cement jet grouting pile and construction method thereof
The invention relates to the technical field of building construction, and particularly discloses an anti-erosion cement jet grouting pile and a construction method thereof. The slurry of the jet grouting pile is prepared from the following components in parts by weight: 200 to 260 parts of Portland cement, 20 to 40 parts of slag powder, 110 to 150 parts of water, 4 to 8 parts of anti-crack fiber, 18 to 26 parts of water swelling rubber powder, 2 to 4 parts of magnesium aluminum hydrotalcite powder, 0.2 to 0.6 part of SAP resin and 2.2 to 3.0 parts of polycarboxylate superplasticizer. The anti-erosion cement jet grouting pile has a good resistance effect on chloride ion erosion, can still keep high strength under the action of chloride ion erosion, can fully reinforce foundation soft soil under the condition that the chloride ion concentration in soil and underground water is high, and is suitable for being applied to a maritime work environment or an inland saline-alkali environment.
本申请涉及建筑施工技术领域，具体公开了一种抗侵蚀水泥旋喷桩及其施工方法。旋喷桩的浆液包括如下重量份的组分：硅酸盐水泥200‑260份，矿渣粉20‑40份，水110‑150份，抗裂纤维4‑8份，吸水膨胀胶粉18‑26份，镁铝水滑石粉2‑4份，SAP树脂0.2‑0.6份，聚羧酸减水剂2.2‑3.0份。本申请的抗侵蚀水泥旋喷桩对氯离子侵蚀具有良好的抵抗效果，在氯离子侵蚀作用下仍然能够保持较高的强度，能够在土壤和地下水中氯离子浓度较高的情况下实现对地基软土的充分加固，适合应用于海工环境或内陆盐碱环境。
