Steam-curing-free high-strength anti-corrosion pipe pile and preparation method thereof
The invention relates to a steam-curing-free high-strength anti-corrosion pipe pile and a preparation method thereof, and belongs to the technical field of pile foundations. The steam-curing-free high-strength anti-corrosion pipe pile comprises 250 to 320 parts of cement, 1000 to 1200 parts of fine aggregate, 1300 to 1500 parts of coarse aggregate, 120 to 210 parts of water, 40 to 60 parts of fly ash, 50 to 70 parts of mineral powder, 6.5 to 8.5 parts of a water reducing agent, 20 to 25 parts of nano calcium carbonate, 0.12 to 0.2 part of sodium hexametaphosphate, 2 to 5 parts of chitosan modified basalt fiber and 10 to 18 parts of polydimethylsiloxane. The preparation method comprises the following steps: uniformly mixing the components to obtain concrete slurry; feeding the obtained concrete slurry into a pipe pile mold with a reinforcement cage, and performing centrifugal forming; hoisting the centrifuged pipe pile mold into a normal-pressure maintenance pool for maintenance; and demolding after curing to obtain the pipe pile. The corrosion-resistant pipe pile has the effect of improving the corrosion resistance of the pipe pile, so that the durability of the pipe pile is improved.
本申请涉及一种免蒸养高强度防腐管桩及其制备方法，属于桩基础技术领域，其按重量份计，包括250‑320份水泥、1000‑1200份细骨料、1300‑1500份粗骨料、120‑210份水、40‑60份粉煤灰、50‑70份矿粉、6.5‑8.5份减水剂、20‑25份纳米碳酸钙、0.12‑0.2份六偏磷酸钠、2‑5份壳聚糖改性的玄武岩纤维、10‑18份聚二甲基硅氧烷。制备方法：将各组分混合均匀得到混凝土浆料；将得到的混凝土浆料送入装有钢筋笼的管桩模具中，离心成型；将离心后的管桩模具吊入常压养护池进行养护；养护结束后脱模得到管桩。本申请具有提高管桩的耐腐蚀性能，从而提高管桩的耐久性的效果。
