Drilling and burying type prefabricated miniature pipe pile for power transmission line and construction method of drilling and burying type prefabricated miniature pipe pile
The invention discloses a drilling and burying type prefabricated miniature tubular pile for a power transmission line and a construction method of the drilling and burying type prefabricated miniature tubular pile, and belongs to the field of power transmission line construction. The drilling and burying type prefabricated miniature tubular pile comprises an internal flow guide component and an external positioning and nesting component which form a pile body, and the internal flow guide component is composed of a flow guide steel pipe, a prefabricated miniature tubular pile and a grouting head; the grouting head is composed of a prefabricated steel pipe, a top sealing steel plate, a bottom sealing steel plate and a plurality of stiffening ribs, and the internal flow guide component and the external positioning nesting component are connected through poured high-strength cement mortar. According to the drilling and burying type prefabricated miniature pipe pile for the power transmission line, the prefabricated pipe pile body is buried through drilling, high-strength mortar is pressed into the gap in the outer side of the pipe pile through the grouting device, the mortar and the PHC pipe pile body form a common stress structure, all components of the designed drilling and burying type prefabricated miniature pipe pile for the power transmission line are prefabricated in a factory and assembled on site, construction is easy and convenient, influences on the environment are small, and manpower and material resources are saved; and full-mechanical construction of the power transmission line foundation is realized.
本发明公开了一种输电线路钻埋式预制微型管桩及其施工方法，属于输电线路施工领域，包括构成桩身主体的内部导流构件和外部定位嵌套构件，所述的内部导流构件由导流钢管、预制微型管桩和注浆头组成，所述注浆头由预制钢管、封顶钢板、封底钢板和多个加劲肋组成，所述内部导流构件和外部定位嵌套构件由灌注的高强度水泥砂浆连接。本发明通过钻孔埋入预制管桩主体，通过压浆装置在管桩外侧缝隙中压入高强度砂浆，砂浆与PHC管桩主体形成共同的受力结构，设计的输电线路钻埋式预制微型管桩各构件工厂预制，现场组装，施工简单便捷，对环境影响小，节省人力物力，实现了输电线路基础的全机械化施工。
