NPD3500 Pebble Crushing Mud-Water Balance Pipe Jacking Machine

Product Overview

The NPD3500 Pebble Crushing Mud-Water Balance Pipe Jacking Machine is high-performance underground tunneling equipment spe

cially developed for trenchless construction projects in pebble layers, gravel formations, and mixed geological environments.

This Slurry Balance Pipe Jacking Machine adopts advanced polygonal eccentric crushing technology combined with intelligent slurry circulation systems to provide powerful pebble crushing capability and stable excavation performance during underground tunneling operations.

As a professional micro tunneling machine and MTBM solution, the NPD3500 is widely used in municipal sewer construction, underground utility tunnel engineering, and long-distance trenchless pipeline installation projects.

Compared with conventional Pipe Jacking equipment, this Pebble Crushing Pipe Jacking Machine provides stronger geological adaptability and more stable tunneling efficiency in difficult underground construction conditions.

Pebble Crushing Technology

The polygonal eccentric crushing structure is specially optimized for pebble layer excavation and underground tunneling operations in complex geological conditions.

During trenchless construction operations, the eccentric cutter disc continuously crushes pebbles, gravel, stones, and hard spoil materials, improving spoil transportation capability and tunneling efficiency.

Each edge of the polygonal cutter disc and the polygonal soil chamber shell generates secondary crushing effects, significantly enhancing excavation capability in underground tunneling projects.

This slurry balance pipe jacking machine can efficiently process pebble formations that are difficult for traditional micro tunneling equipment and conventional MTBM systems.

The optimized crushing structure also reduces blockage risks and improves operational reliability during long-distance underground pipeline installation projects.
