The provincial public security organ has repaired and repaired the damaged steel mesh on the Penghu expressway, strictly prevented pedestrians and animals from driving at high speed, and resolutely put an end to the road traffic accidents caused thereby. The brigade police carefully touch the damaged steel mesh with steel wire rope, steel bar and steel bar to eliminate the hidden danger in time.
Register and summarize the serious steel mesh defects in detail, and inform the owner unit in time for rectification. In the process of construction, 20 steel nets were damaged and 16 sites were repaired. The unqualified steel mesh directly endangers our lives.
Steel mesh is also used to lay the deck. At present, most of the steel mesh produced is used for bridge deck pavement. As we all know, in recent years, the bridge collapse accidents are often caused by the property loss. The specification and size of steel bar safety hazards shall be designed in accordance with national standards, and the quality of steel mesh shall be produced in strict accordance with national standards and specifications.
The longitudinal and transverse reinforcement of the reinforcement grid form a network structure, which has good anchorage performance with the concrete and uniform load distribution, which significantly improves the anti-seismic cracking performance of the reinforced concrete structure. Laying welded steel mesh on the road can reduce more than 75% of the cracks. The use of steel mesh can make the construction faster. As long as the steel mesh is laid according to the requirements, the concrete can be poured, the reinforcement can be cut off, placed one by one, and the support and other links can be ignored.
