The arch installation trolley is a multifunctional piece of construction equipment that plays a crucial role in tunnel construction. This equipment not only improves construction efficiency but also enhances safety. Here are the main functions of the arch installation trolley in tunnel construction.
1. Steel Frame Installation
One of the primary functions of the arch installation trolley is to install steel frames inside tunnels. The steel frame acts as the skeleton of the tunnel structure, supporting its stability and safety. By using the installation trolley, the steel frames can be accurately positioned and quickly installed, increasing work efficiency and installation precision.
2. Mesh Installation
In addition to steel frames, the arch installation trolley is also used for installing mesh. The mesh is part of the tunnel lining, used to distribute and absorb ground stress, preventing rock loosening and collapse. The installation trolley can carry and secure the mesh, allowing it to be installed quickly and accurately.
3. Connecting Bar Installation
Connecting bars are crucial components between steel frames and mesh, ensuring the integrity and stability of the entire support structure. The arch installation trolley assists in the installation of connecting bars, ensuring each connection point is firm and reliable.
4. Assisting in Inspection and Hazard Mitigation
Safety inspections and hazard mitigation are vital during tunnel construction. The arch installation trolley is equipped with relevant devices and tools, assisting construction personnel in conducting safety inspections and hazard mitigation work, promptly identifying and addressing potential dangers to ensure construction safety.
5. Under-excavation Handling
During tunnel excavation, under-excavation may occur, where the actual excavation size is smaller than the design size. The arch installation trolley can assist construction personnel in handling under-excavation, ensuring the tunnel cross-section meets design requirements.
6. Explosive Installation
In tunnel construction requiring blasting operations, the installation of explosives is a critical step. The arch installation trolley is equipped with safety protection devices and operation platforms, aiding construction personnel in safely and accurately installing explosives, ensuring the safety and effectiveness of blasting operations.
7. Rock Bolt Installation
Rock bolts are a crucial part of tunnel support, used to stabilize the surrounding rock and prevent collapses. The arch installation trolley can carry rock bolts and installation equipment, assisting construction personnel in installing rock bolts, thereby improving construction efficiency and safety.
The arch installation trolley integrates several key processes in tunnel construction. Its multifunctional applications significantly enhance construction efficiency, quality, and safety. The widespread use of this equipment provides solid support for tunnel construction.
