[0002] The pipe jacking construction technology generally involves making a working well vertically on the ground, and then using a high-pressure hydraulic jack to push cement or steel pipes with lubricating media into the ground. Through the force-transmitting jacking iron and guide rails, the hydraulic jack supported on the rear seat of the foundation pit presses the pipe into the soil layer, while digging and transporting away the soil in front of the pipe. When the first section of the pipe is completely pushed into the soil layer, the second section of the pipe is connected to the back and continues to push forward.
