Large-diameter steel pipe anti-slide pile anti-corrosion protection layer and construction method thereof
The invention belongs to the technical field of steel pipe anti-slide pile protection, and particularly relates to a large-diameter steel pipe anti-slide pile anti-corrosion protection layer and a construction method thereof. The problems existing in existing anti-corrosion coating protection and electrochemical protection are solved. According to the scheme, the large-diameter steel pipe anti-slide pile anti-corrosion protection layer comprises a concrete core pile poured on a slide mass and a slide bed, wherein a steel pipe is arranged on the concrete core pile, and a fiber concrete protection layer, a macromolecule corrugated pipe and a grouting body are sequentially arranged on the steel pipe from inside to outside. The specific construction method comprises the steps that mechanical hole forming or hole digging is carried out, and the hole depth is checked; the steel pipe is hoisted, positioned and temporarily fixed; the macromolecule corrugated pipe is mounted; a positioning support is mounted and unfolded; the concrete core pile is poured; the fiber concrete protection layer is poured; and the grouting body is poured. The technology of the large-diameter steel pipe anti-slide pile anti-corrosion protection layer can be adopted in a site with high corrosivity and can also be used in an area with the high underground water level, the problem that a steel pipe anti-slide pile is poor in corrosion resistance can be solved, and the durability and service performance of the steel pipe anti-slide pile are improved.
本发明属于钢管抗滑桩防护技术领域，具体涉及到一种大直径钢管抗滑桩防腐保护层及其施工方法；克服现有防腐涂层防护和电化学保护存在的诸多问题，本方案包括浇筑于滑坡体和滑床上的混凝土芯桩，在混凝土芯桩上设有钢管，所述钢管上由内至外依次设有纤维混凝土保护层、高分子波纹管和注浆体。具体施工包括：机械成孔或者挖孔，并检查孔深；吊装钢管，定位并临时固定；安装高分子波纹管；安装定位支架并展开；浇筑混凝土芯桩；浇筑纤维混凝土保护层；浇筑注浆体。本发明提供的大直径钢管抗滑桩防腐保护层的技术可在具有较强腐蚀性的场地采用，也可在地下水位较高的地区使用，可以克服钢管抗滑桩耐腐蚀性差的问题，提高其耐久性和服役性能。
