Abstract

The invention provides Y-shaped pipe jacking equipment. A back half Y frame and a front half Y frame synchronously and relatively do forward and backward movement; in the synchronous relative forward and backward movement process of the back half Y frame and the front half Y frame, first stirring teeth and second stirring teeth which are arranged on the back half Y frame and first stirring teeth and second stirring teeth which are arranged on the front half Y frame drill soil in a range beyond four stirring drill bits but within a Y frame formed by the back half Y frame and the front half Y frame, and the soil is stirred with water to form slurry; the slurry is discharged out of a jacking pipe by a slurry pump; the pipe jacking equipment forms a hole with the Y-shaped cross section in the propelling process; then, a pipeline with the Y-shaped cross section forms a long-distance Y-shaped pipe jacking pipeline in the section-by-section following process. The full-cross-section cutting is used, so that the resistance is small during the pipe jacking.

Description

technical field [0001] The invention relates to a pipe jacking device, in particular to a Y-shaped pipe jacking device used in pipe jacking projects. Background technique [0002] At present, the Y-shaped pipe jacking equipment used in pipe jacking projects all use multiple drill bits to rotate and cut the soil to form an approximately Y-shaped section, and the resistance of the Y-shaped pipe jacking pipe is very large during the pressing process. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a Y-shaped pipe jacking device. [0004] The present invention is achieved through the following technical solutions: [0005] A Y-shaped pipe jacking equipment, the outer ring of the actuator is fixed to the Y-shaped shell through a partition, the right end of the actuator is equipped with a motor, and the right end of the motor is fixed with a pressure arm; the left end of the actuator is equipped with agitator shaft 1 and...
