TECHNICAL FIELD
[0001] The utility model relates to a pipe jacking construction technical field, concretely to a mud balance mechanical jacking device for pipe jacking into a shaft. BACKGROUND

The mud balance pipe jacking is a mechanical automatic pipe jacking construction method which cuts soil in the full section, balances the soil pressure and the underground water pressure by using the mud water pressure, and uses the mud water as the medium for conveying the discarded soil. The basic principle is mud water protection wall. In the pipe jacking construction, the excavated surface must be kept stable, and a certain pressure of mud water must be injected into the mud water tank. The mud water penetrates into the soil under the pressure, and forms a layer of mud skin on the excavated surface, which prevents the mud water from continuing to penetrate into the soil, and the pressure of the mud water acts on the excavated surface through the mud skin to prevent collapse. The jacking head needs to be connected with the mud water pipe to balance the mud water pressure. After the concrete pipe is jacked into the construction channel, a person needs to enter the pipe to disconnect the connection between the mud water pipe and the jacking head, place a new concrete pipe, and then reconnect. With the deepening of the concrete pipe, the distance between the jacking head and the outlet becomes longer, and the time required for the personnel to enter becomes longer, which consumes a lot of working time and also has safety hazards. Therefore, the mud balance mechanical jacking device for pipe jacking into a shaft is provided. CONTENT OF THE UTILITY MODEL
