Application scenarios and market development of tunnel robot shotcrete machine

  1. Core application areas: Tunnel robot shotcrete machine play a key role in many fields with their excellent performance. In the construction of railway and highway tunnels, it accounts for as much as 65%. Whether it is a high-speed railway tunnel that crosses mountains and ridges, or a highway tunnel that crosses rivers, it can efficiently complete the concrete spraying support operation to ensure the smooth progress of the project; in the field of mine tunnel construction, its 20% application ratio reflects its good adaptability to complex geological conditions and builds a solid safety barrier for mineral resource mining; in water conservancy and hydropower projects, the 10% application ratio highlights its important value in ensuring construction quality and safety in underground water transfer tunnels, underground powerhouses of hydropower stations and other projects.

   2. Benchmark project practice: Many national key projects have introduced robot shotcrete machine to provide solid guarantees for project quality. In the construction of Naqing Expressway, facing the complex karst landform, the wet spraying trolley effectively coped with geological problems such as caves and fissures with precise spraying technology and efficient construction capabilities to ensure the stability of the initial support of the tunnel; in the Yanjiang Expressway project, the wet spraying trolley achieved rapid transfer and high-quality spraying operations in the construction of long-distance and large-section tunnels, greatly shortening the construction period and becoming a "capable general" for engineering construction.

  3. Industry development trend: From the market data, the global market is expected to grow at a compound annual growth rate of 8.2% from 2023 to 2029, and the industry has broad prospects. Chinese manufacturers occupy an important position in the global market, with a production capacity of up to 45%. They not only meet domestic infrastructure needs, but also rely on their technological advantages and cost-effectiveness to actively explore the international market and promote tunnel wet spraying trolley technology to the world.
