Abstract
Description
Technical field
[0001] The invention belongs to the field of structural engineering. More specifically, it relates to a top-supporting arc steel plate external prestressed steel cable diverter, which is mainly used to realize external prestressing by using the diverter when the existing structure is reinforced by external prestressing. The steering of the stress cable. Background technique
[0002] Most of the existing more than 600,000 bridges in my country have a low design load level, many bridges have diseases and cannot meet the actual vehicle traffic requirements. They are in overload and "diseased" operation. These bridges need to be reinforced and reconstructed And other ways to improve its carrying capacity. The old bridge reinforcement methods can be summarized as active and passive reinforcement methods. Active reinforcement method is relatively complex in technology, but it has better reinforcement effect and can be artificially intervened in structural forces and is...
