Technical field
The utility model is related to concrete dam technical fields, more particularly, to a kind of bracing means of concrete dam.
Background technology
The dam body of concrete dam is often cracking under various load actions during longtime running, influences big
Dam safety and anti-permeability performance reduce dam durability, need to carry out consolidation process.In reinforcing engineering, for different dams
Actual conditions, generally can be used and the force methods such as reinforce before dam body surface treatment, grouting treatment, dam post-reinforcing and dam.In general,
In the case that dam body surface treatment has been only applicable to dry working face, for the surface crack ratio at the top of dam body downstream face or dam body
It is appropriate.In the place for having grouting condition, using grouting treatment and the effective means of dam body consolidation, but application conditions are limited
System.It is larger for dam body cracking range, when dam body stress and stabilization are a greater impact, in order to ensure the safety of dam, often
It needs to be reinforced comprehensively by the way of widening dam body.The mode for widening dam body generally has two kinds of reinforcing before dam post-reinforcing and dam
Mode, still, dam post-reinforcing are generally unfavorable to improving dam anti-permeability performance, and reinforcing mode can improve dam before using dam
Anti-permeability performance, but reinforced before dam and need to be vented reservoir, construction is relatively difficult, is not easy to construct.
