Threaded pipe pile suitable for weathered gravel soil layer
The invention discloses a threaded pipe pile suitable for a weathered gravel soil layer, the pipe pile is a hollow cylindrical body and comprises a pipe pile wall, a pipe pile inner cavity and threads arranged outside the pipe pile wall, the top of the pipe pile is provided with a bolt and a support embedded part, and the outer side of the pipe pile wall and the surfaces of the threads, the bolt and the support embedded part are provided with metal coatings; a colloid layer is arranged on the surface of the metal coating outside the pipe pile wall; after construction, anticorrosive coatings are arranged outside the colloid layer on the surface of the pipe pile wall, the metal coating on the surface of the bolt and the metal coating on the surface of the support embedded part outside the soil layer. According to the threaded pipe pile provided by the invention, the surface corrosion resistance is improved by adopting the metal coating, the coating is protected by adopting the colloid layer, the part outside the soil layer is protected by the anti-corrosion coating, and the balance of protectiveness and economy is achieved by reasonably setting the coating parameters, the thread spacing and the outer diameter of the pipe pile.
本发明公开了一种适用于风化砂砾土层的螺纹管桩，所述管桩为空心柱状体，包括管桩壁、管桩内腔和设置于管桩壁外的螺牙，所述管桩顶部设置有螺栓和支架埋件，所述管桩壁外侧、螺牙、螺栓和支架埋件表面设置有金属镀层；所述管桩壁外的金属镀层表面设置有胶体层；施工后，位于土层外的管桩壁表面胶体层、螺栓表面金属镀层和支架埋件表面金属镀层外设置有防腐涂层。本发明提供的螺纹管桩，采用金属镀层提高表面抗腐蚀性，采用胶体层保护镀层，防腐涂层保护土层外的部分，合理设置涂层参数、螺牙间距和管桩外径达到保护性和经济型的平衡。
