Soil body curing agent and rotary spraying anchor pile construction process applying soil body curing agent
The invention discloses a soil body curing agent and a rotary spraying anchor pile construction process applying the soil body curing agent, and relates to the technical field of anchor pile construction. The soil body curing agent is prepared from the following raw materials in percentage by weight: 40-60% of cement, 20-35% of desulfurization gypsum, 10-20% of slag powder, 0.01-1% of a water reducing agent and 0.01-5% of a sulphoaluminate exciting agent, wherein P.O.42.5 cement or P.O.52.5 cement is adopted as the cement. Compared with common cement, the soil body curing agent can reduce the construction cost, improve the strength and the anchoring effect of an anchor pile, realize waste recycling and facilitate solving the pollution problem. The invention further provides a construction process of a selective spraying anchor pile. According to the invention, by using the soil body curing agent, the construction cost is effectively reduced, the strength and the anchoring effect of the anchor pile are improved, pollution is reduced, waste recycling is achieved, and good economic benefits are achieved.
本发明公开了一种土体固化剂及应用该土体固化剂的旋喷锚桩施工工艺，涉及锚桩施工技术领域。其中，一种土体固化剂，由下述重量百分比含量的原料组成：水泥40‑60％、脱硫石膏20‑35％、矿渣粉10‑20％、减水剂0.01‑1％、硫铝酸盐激发剂0.01‑5％；所述水泥采用P.O.42.5水泥或P.O.52.5水泥；相较于普通水泥，该土体固化剂能够降低施工成本，提高锚桩的强度和锚固效果，并能实现废弃物资源化，有助于解决污染问题。同时，本发明还提供了一种选喷喷锚桩的施工工艺，应用上述土体固化剂，有效降低施工成本，提高锚桩强度和锚固效果，减少污染，并实现废弃物资源化，具有良好的经济效益。
