With the popularization of trenchless construction technology in the infrastructure field, higher requirements have been put forward for the professionalism, adaptability and service response speed of pipe jacking equipment. Relying on core technology R&D and a full-chain service system, Jiangsu Xinlilai Heavy Industry Technology Co., Ltd. creates an integrated pipe jacking construction solution of "equipment supply + technical support + after-sales maintenance" for customers, effectively solving construction problems and improving project efficiency.

In equipment R&D, Xinlilai Heavy Industry has achieved precise breakthroughs for different construction scenarios. For the laying needs of small-diameter sewage, rainwater-sewage diversion and thermal pipelines, the company has launched spiral pipe jacking main machines and spiral micro-jacking tool heads. The equipment is compact in size and can be constructed in a circular working well with a diameter of 2600mm. The spiral micro-jacking tool head adopts hydraulic transmission without electrical components, and supports the interchange of multiple shells and the replacement of sockets and spigots, realizing multi-purpose of one machine and greatly reducing construction costs. For complex composite strata, its independently developed slurry balance 1200-type pipe jacking equipment with secondary crushing function has been successfully exported to India, helping to advance overseas infrastructure projects smoothly.

To ensure the smooth progress of the entire construction cycle, Xinlilai Heavy Industry has built a sound service system. The company promises to respond within 24 hours upon receiving customer service information, can provide full-process technical support for equipment installation, commissioning, operation and maintenance, and keeps various spare parts in stock to ensure quick resolution of equipment failures, achieving the goal of "starting with customer needs and ending with customer satisfaction". In addition, the company also provides construction technical guidance for customers, assists in analyzing construction problems and formulating solutions, realizing all-round guarantee from equipment to technology.

In the recently completed Huanggang Yi'ai Lake pipe jacking project of China Railway 11th Bureau Group, the YSD2000-type rock pipe jacking machine provided by Xinlilai Heavy Industry successfully completed rock stratum tunneling with its strong power and high-efficiency crushing capacity. In the Guangzhou power pipe gallery project, the NPD3000-type pipe jacking equipment operated accurately, ensuring the smooth laying of the power pipe gallery. These successful cases have verified the practicability and reliability of Xinlilai's integrated solutions.
