Problems solved by technology

When the pile foundation is poured on site, the construction machinery will drill holes on site, the steel bars will be bound on site, and the concrete will be mixed on site, which has the disadvantages of large manpower consumption, large noise pollution, long construction period, and high cost. Excessive thickness of sediment, collapse of holes, and rapid pile extraction lead to problems such as necking of the pile body, making it difficult to guarantee the quality of the pile body. At the same time, a large amount of mud garbage will be generated during the construction process, and the construction environment on site is poor. Difficult to handle, high requirements for environmental protection

Abstract

The invention relates to a drill-buried type prefabricated pipe pile for an electric transmission line. The drill-buried type prefabricated pipe pile comprises an internal flow-guiding component, a flow-guiding steel pipe, a prefabricated miniature pipe pile, a grouting head, a grouting head top plate, a grouting hole, a grouting steel pipe, a grouting head bottom plate, reinforcing ribs, an open hole, a top plate, a pore, bolt holes, an external positioning nesting component, four fork feet, angle steel and mortar, the internal flow-guiding component and the external positioning nesting component are connected through the grouted mortar, the internal flow-guiding component comprises the flow-guiding steel pipe, the prefabricated miniature pipe pile and the grouting head, the reinforcing ribs are welded into the grouting steel pipe, the open hole is formed in the grouting steel pipe, the top plate is welded to the top of the flow-guiding steel pipe and provided with the pore, the bolt holes are formed in the four corners of the top plate, and the four fork feet are welded to the outer wall of the external positioning nesting component through the angle steel at equal distances. The drill-buried type prefabricated pipe pile has the advantages of small environmental influence, high construction efficiency, reliable quality and low cost, and is suitable for being used and promoted.

Description

technical field [0001] The invention relates to a drilled and buried prefabricated pipe pile for power transmission lines. Background technique [0002] my country has a vast territory, and the transmission line construction project is huge. The traditional transmission line pile foundation is mainly formed by on-site pouring. When the pile foundation is poured on site, the construction machinery will drill holes on site, the steel bars will be bound on site, and the concrete will be mixed on site, which has the disadvantages of large manpower consumption, large noise pollution, long construction period, and high cost. Excessive thickness of sediment, collapse of holes, and rapid pile extraction lead to problems such as necking of the pile body, making it difficult to guarantee the quality of the pile body. At the same time, a large amount of mud garbage will be generated during the construction process, and the construction environment on site is poor. It is difficult to h...
