Method for replacing integral dropper of whole anchor section of 350 km/h high-speed rail contact network

The invention discloses a method for replacing an integral dropper of a whole anchor section of a 350 km/h high-speed rail contact network, and belongs to the technical field of high-speed rail operation updating and reconstruction. The method comprises the following eight steps: dropper calculation parameter measurement, electricity testing and grounding, simultaneous tension application to two ends of a contact line, integral dropper replacement in the integral anchor section, repeated measurement of various parameters, fine adjustment and defect elimination, online horizontal pushing acceptance and ground wire removal and marking. The dropper calculation parameter measurement is carried out in a first skylight point, and electricity testing and grounding, simultaneous tension application to two ends of a contact line, integral dropper replacement in the integral anchor section, repeated measurement of various parameters, fine adjustment and defect elimination, online horizontal pushing acceptance and groun
