The Integrated Arch – Anchoring – Shotcreting Trolley is an advanced mechanical equipment used in the construction of underground projects such as tunnels and mine roadways. It integrates three key support operations: arch – frame installation, rock – bolt construction, and shotcrete spraying, which greatly improves the efficiency and quality of underground engineering support construction.

In terms of arch – frame installation, the trolley is equipped with precise robotic arms and a positioning system. It can quickly and accurately grasp and install steel arch frames, ensuring the precise installation position of the arch frames in the tunnel or roadway, and providing a stable basic support for subsequent support operations.

During the rock – bolt construction process, this trolley can efficiently complete a series of operations such as drilling, rock – bolt installation, and grouting. Its advanced drilling equipment can accurately drill rock – bolt holes of appropriate depth and diameter according to different geological conditions. Then, the rock bolts can be smoothly inserted and grouted, so that the rock bolts are closely combined with the surrounding rock, enhancing the stability of the surrounding rock.

When performing shotcrete spraying operations, the spraying system of the trolley can accurately control the amount, pressure, and angle of shotcrete spraying according to construction requirements, enabling the concrete to be evenly sprayed onto the surface of the surrounding rock to form a solid support layer. This promptly seals the surrounding rock and prevents it from weathering and collapsing.

The Integrated Arch – Anchoring – Shotcreting Trolley is usually equipped with an intelligent control system. Operators can control various operations through the operation panel or remote control, which not only reduces labor intensity but also improves the safety and accuracy of construction. In addition, its compact and reasonable structural design enables it to operate flexibly in narrow underground spaces, adapting to different construction sites and working conditions. With its high – efficiency and multi – functional characteristics, the Integrated Arch – Anchoring – Shotcreting Trolley plays an indispensable and important role in modern underground engineering construction.
