In municipal engineering applications, chain trenching machines demonstrate outstanding performance. Equipped with efficient asphalt-cutting capabilities, these machines enable rapid and precise road surface excavation, providing robust support for pipeline installation while significantly enhancing project efficiency. For oil and gas pipeline construction, the integrated system combining rock-cutting cutterheads with wear-resistant picks effectively breaks through gravel-stratum geological challenges. This coordinated operation ensures high-precision trenching execution, establishing a solid technical foundation for safe pipeline installation in complex geological environments.
