Description
Technical field
The present invention relates to large-span cast-in-situ arch bridge arch knots in cast-in-place concrete bridge construction field, especially high mountain gorge
Structure and method for dismounting in situ.
Background technology
Due to big with span ability, the characteristics such as durability is good are widely used concrete arch-type bridge, are particularly suitable in high mountain
It is built in valley, large-span cast-in-situ concrete arch-type bridge is built in valley frequently with tool-type steel construction arch as supporting, is waited for
Top arch ring concreting needs arch carrying out disengaging dismounting after finishing the intensity for reaching certain.Due to top concrete arch
Circle blocks, and is usually used goes out after concrete arch ring to carry out decomposing again hanging by arch whole lateral moving at this stage, be traversing
And it is mostly to need the temporary structure processed using the support of articulated structure sandbox and sliding rail to unload frame to facilitate the arch springing of general arch
More, when mounted due to sandbox support and articulated structure poor controllability, low construction efficiency, arch frame structure holds when arch traversing dismounting
Easy unstability, security risk is big, needs a large amount of temperature pier.
