The construction process of the tunnel wet spraying manipulator is an efficient and precise tunnel construction method. Through hydraulic technology and automation equipment, the premixed concrete is quickly and evenly sprayed onto the construction surface to form a solid concrete support layer. This process is widely used in railway and highway tunnels, water conservancy and hydropower culverts, underground mines and other fields. The following is a detailed introduction to the construction process of the wet spraying manipulator.

  Construction process flow

   The construction process of the tunnel wet spraying manipulator is mainly divided into the following steps:

   Preparation of premixed concrete: Before the construction begins, the concrete needs to be mixed according to the predetermined ratio. The premixed concrete has good fluidity and adhesion, which can ensure the spraying effect.

   Concrete transportation: The premixed concrete is transported to the nozzle through a pipeline using a hydraulic system. The use of hydraulic pressure ensures the stability and continuity of the concrete during the transportation process, avoiding blockage and uneven transportation.

   Nozzle connection compressed air and accelerator: Compressed air and accelerator are connected at the nozzle. The role of compressed air is to enable the concrete to obtain sufficient power and speed during the spraying process to ensure that it can evenly cover the sprayed surface. The accelerator can accelerate the coagulation and hardening of concrete and improve construction efficiency.

   Concrete spraying: Concrete is sprayed onto the sprayed surface at high speed through the nozzle. Due to the action of compressed air and accelerator, the concrete can quickly coagulate and form a solid support layer. This process ensures the adhesion and density of the concrete and effectively improves the construction quality.

   Coagulation and hardening: The concrete sprayed onto the sprayed surface will coagulate and harden in a short time, and finally form a solid concrete support layer, providing the necessary support and protection for the tunnel.

   The construction process of the tunnel wet spraying manipulator has broad application prospects in modern tunnel engineering due to its high efficiency, safety and environmental protection. With the continuous development and improvement of technology, the wet spraying manipulator will play an important role in more fields and more complex projects, and promote tunnel construction towards higher quality, higher efficiency and higher safety.
