Prestressed anchors have made considerable progress in recent years, and are mainly used in highway and railway bridge construction
Prestressed anchors have made considerable progress in recent years, and are mainly used in highway and railway bridge construction, urban overpass and light rail construction, high-rise buildings, water conservancy and hydropower dam construction, port and wharf construction, rock slope protection and anchoring , Building foundation reinforcement project, tunnel and mine roof anchor roof, prestressed grid, large warehouse building construction, sliding film intermittent propulsion project, bridge and tunnel jacking construction, large container and some ships, sleepers replacement bridge support projects, buildings Carbon fiber reinforcement, pre-tensioned beam field construction, external pre-stressed engineering, and pre-stressed anchors are often used in anti-magnetic and anti-corrosion projects.
As more and more prestressed products are applied to specific construction, the protection of prestressed product materials mainly includes the following aspects: related prestressed materials, anchors, etc. must be clean and clean, and in the storage of related materials and During the handling process, care should be taken to avoid mechanical damage and harmful corrosion; when the prestressed materials are stored in the warehouse, the warehouse must be dry, moisture-proof, have good ventilation conditions, and no corrosive medium is allowed. If the prestressed material is stored in an outdoor empty field, the storage time should not exceed half a year, and it is strictly forbidden to directly stack the prestressed anchor material on the ground. It is necessary to put sleepers under the prestressed material and must use tarpaulin for effective Coverage measures. The relevant pre-stressed anchors, fixtures and connectors must be kept by a special person, and be registered in a timely manner, and the records should be properly kept. The overhead drive link method uses a special shelf installed at the bottom of the driving head and the wellhead tensioning equipment for effective connection.
