The reinforcement mesh of tunnel is mainly used in the following aspects: building surface reinforcement or crack prevention, building bearing, beam column reinforcement, foundation construction, roof bearing or floor heating installation, outdoor pavement crack prevention treatment, foundation, floor, roof, etc. Now let Jinan Steel wholesale with you to have a look.
The reinforcing mesh of tunnel is made in factory and welded with cold-rolled ribbed bar or cold-rolled plain round steel bar. It is a good and efficient material for concrete distribution. It is of great significance to improve the construction efficiency, structure quality, safety and reliability, and to change the traditional construction methods. It can be used for reinforcement of reinforced concrete structure and ordinary reinforcement of prestressed concrete structure. In order to standardize the production and application of this material and promote the industrialization level of China's construction industry.
The key points for attention in the construction of tunnel steel mesh are as follows:
The reinforcement mesh shall be installed after the construction of system anchor rod. The type of reinforcement and grid spacing shall be made into mesh outside the tunnel according to the design requirements. When it is installed in the tunnel, the gap between it and the initial shotcrete surface shall not be greater than 3cm, and the crossing point of the reinforcement mesh and the anchor rod shall be welded together, so that the reinforcement mesh is not easy to shake during spraying. Attention should be paid to the installation of steel mesh: the reinforcement should be straightened, derusted and greasy before fabrication to ensure the construction quality.
