Intermediate jacking station for prefabricated reinforced concrete jacking pipe

Abstract

The invention discloses an intermediate jacking station for a prefabricated reinforced concrete jacking pipe, relates to the technical field of intermediate jacking stations, and aims at solving the problems that an existing intermediate jacking station only provides power through a jack, the jacking force is limited, the construction requirement under the long-distance or complex geological condition is difficult to meet, the large load is prone to being damaged due to overload work, and the working efficiency is poor. And the maintenance cost is increased. The inner wall of the front connecting pipe is connected with the inner wall of the rear connecting pipe through a pushing mechanism, an adjusting mechanism is arranged beside the pushing mechanism, and the adjusting mechanism is connected with the pushing mechanism. Through the cooperation between the pushing mechanism and the adjusting mechanism, extra jacking force can be provided, the relay station is helped to more efficiently push a pipeline to advance, the auxiliary pushing mechanism shares part of the jacking force, the load of the jack is reduced, the service life of the jack is prolonged, the auxiliary pushing mechanism can uniformly distribute the jacking force, and the jacking efficiency is improved. The offset or vibration of the intermediate jacking station in the jacking process is reduced, and the pushing mechanism can provide stronger jacking force.
