Power transmission line emergency rescue iron tower base construction method
The invention relates to a power transmission line emergency rescue iron tower base construction method. At present, according to a high-pressure jet grouting pile for emergency rescue iron tower base construction, cement paste is sprayed into a soil layer through a high-pressure rotating nozzle to be mixed with a soil body, a continuously-lapped cement reinforcing body is formed, the environment is prone to being polluted, and the cost is high. A construction method for an emergency rescue iron tower base of a power transmission line comprises the steps that cement grout is prepared according to the mass ratio according to the drawing requirements, a horizontal ruler is used for adjusting a drilling machine to be horizontal and a drill rod to be vertical, after hole forming is completed, the drilling machine is moved away, a jet grouting pile machine is used, a grouting pipe is placed downwards to the designed depth, and then a high-pressure water jet pump, a grouting pump and an air compressor are started for jet grouting operation. After slurry is stopped at the bottom of the pile for about half a minute, the drill rod is lifted, and cement slurry, coarse particles in original soil and a new punching body are rotated into a whole by means of the coordination effect of spraying, rotating and lifting. The method is applied to the power transmission line field.
本发明涉及一种输电线路应急救援铁塔基座施工方法。目前，急救援铁塔基座施工高压旋喷桩是以高压旋转的喷嘴将水泥浆喷入土层与土体混合，形成连续搭接的水泥加固体，容易污染环境，成本较高。一种输电线路应急救援铁塔基座施工方法，按图纸要求进行，按质量比配制水泥浆液，用水平尺调整钻机水平及钻杆垂直，成孔完成后将钻机移走，换用旋喷桩机，将注浆管下置至设计深度后，启动高压水射流泵、注浆泵和空压机进行旋喷作业，在桩底停浆约半分钟后提升钻杆，借喷射旋转提升的协调作用，将水泥浆和原土中的粗颗粒及新的冲切体旋转成一体。本发明应用于输电线路领域。
