Background

In the mud-water balance pipe jacking construction process, a pipe piece for tunnel support is single-section jacking in sequence, each time a pipe piece is jacked, pipelines such as mud-water pipelines and power supply systems which are placed inside the pipe piece are required to be disconnected, then new pipe pieces are installed, finally various pipelines are connected and then jacking is resumed, in the jacking process, the pipe piece continuously moves forwards, various pipelines also follow the length (2.5 m) of the moving pipe piece, and the telescopic allowance of the pipeline is required to be considered. The disassembly and connection of the muddy water pipeline are key links affecting the construction efficiency, and the existing construction scheme adopts a rubber steel wire hose as an excessive connecting pipe and utilizes manpower to carry and disassemble. On one hand, when tunneling is performed in a rock stratum or a sandy pebble layer, more stone particles can pass through a slurry discharge pipeline, a hose can be easily worn out to burst a pipe, more cost is increased, and construction safety hazards exist; on the other hand, the diameter of the muddy water pipeline is generally more than 200mm, the muddy water pipeline is very heavy and difficult to bend, and the muddy water pipeline is also greatly wasted in manpower in the continuous disconnection and connection process and has low efficiency. Therefore, the integrated pushing system of the muddy water pipe jacking machine has important practical significance for realizing efficient connection and pushing circulation of the muddy water system.
