Function
Surface cleaning: It can effectively remove impurities such as floating dust, loose materials, and virtual slag on the inverted arch, keeping the surface of the inverted arch clean and providing a good foundation for subsequent construction.
Enhanced adhesion: By grinding the surface of the inverted arch to make it rough, the adhesion between the concrete and the inverted arch is improved, ensuring that the concrete can be tightly combined with the inverted arch after pouring and improving the integrity and stability of the structure.
Structure and materials
Brush head: Usually made of high-strength steel wire or alloy steel, it has good wear resistance, can maintain a good cleaning effect during long-term use, and can also effectively clean and grind the surface of the inverted arch.
Other components: In addition to the brush head, it also includes components such as connecting devices to install the steel brush on the excavator bucket or other equipment, realizing the supporting use of different equipment. Commonly, there are steel brushes suitable for 200 excavators.
Advantages
Improve construction efficiency: Compared with the traditional manual slag cleaning method, using the tunnel inverted arch steel brush in conjunction with equipment such as excavators for cleaning can complete a large area of inverted arch cleaning work in a short time, greatly saving construction time and improving the construction progress. For example, if manual slag cleaning is used, a work team needs to work 2.5 shifts to complete the workload, while using the steel brush head can save about 12 hours.
Reduce costs: It reduces the large amount of labor input required for manual slag cleaning and reduces labor costs. At the same time, improving the construction efficiency also means shortening the construction period of the entire project, indirectly reducing the total cost of the project. Each group of inverted arch construction can save 0.60,000 yuan in costs.
Ensure construction quality: It can more thoroughly remove impurities on the surface of the inverted arch, ensure the flatness and cleanliness of the initial support surface, provide a clean and flat base surface for concrete pouring, thereby improving the project quality and ensuring better combination between the initial support surface of the inverted arch and the inverted arch concrete.
Protect the tunnel structure: The steel brush head has a certain degree of flexibility. During the cleaning process, it can effectively protect the integrity of the primary support surface and the steel arch, avoiding damage caused by improper operations during the cleaning process, thus ensuring the overall stability and safety of the tunnel structure.
The steel brush for tunnel invert is a key tool to ensure the quality of the base surface in invert construction. Its core function is to remove impurities through physical mechanical force, laying the foundation for the subsequent structural layer construction. When selecting the type, it is necessary to consider the tunnel scale, geological conditions and mechanization degree. During the construction, the cleaning scope and quality standards should be strictly controlled. In the future, it will develop in the direction of intelligence and greenness, contributing to the efficient and safe construction of tunnel projects.
