Description
Technical Field
The invention belongs to the technical field of hot-mixed epoxy resin special for steel bridge decks, and particularly relates to a preparation method and application of hot-mixed second-order epoxy adhesive layer oil with excellent construction workability for paving steel bridge decks.
Background
At present, bridge construction is rapidly developed, and the wide application of a new material and a new structure enables the construction technology of large-span bridges such as suspension bridges, cable-stayed bridges and the like to be greatly improved. The steel bridge deck pavement technology is still a difficult problem which is not well solved.
The four innovative concepts of cable-stayed bridges, superposed beams, orthotropic plate steel bridge floors and prestressed concrete segment construction methods have obvious influence on bridge engineering in the world at present, orthotropic steel bridge deck structures have the advantages of light member weight, excellent structural performance, transportation and erection aspects, low construction cost, short construction period and the like, and orthotropic steel bridge decks are mostly adopted for large-span bridge decks which are built in the past or are currently built.
The main girder of the large span bridge built in China generally adopts a steel box girder structure such as a Shanghai Yangpu bridge, a Nanjing Yangtze river two bridge, a RunyingChangjiang river highway bridge, a YangyingChangjiang river bridge, a Xiamen sea cang bridge, a Guangdong Timen bridge, a Wuhan Yang prowl bridge, a Xiling Changjiang river bridge, a Wuhan army Changjiang river bridge, a Hangzhou Bay bridge and the like. Due to the fact that the orthotropic steel bridge deck is large in kneading degree and under the common influence of the traveling load and natural factors such as temperature, wind load and earthquake, the stress and deformation of the orthotropic steel bridge deck are complex compared with those of a highway pavement or an airport pavement, and particularly under the action of the heavy vehicle load, the steel bridge deck is larger in local deformation. The stress of the pavement layer is more complex and unfavorable, and the special use conditions for paving the orthotropic steel bridge deck slab put forward higher requirements on the strength, the deformation stability, the fatigue durability and the like of the pavement material, and simultaneously put forward special requirements on the use performance such as high cohesiveness, light weight, waterproofness and the like. As an important component of a bridge driving system, the comfort, safety, bridge durability, investment benefit and social benefit of driving are directly affected by the pavement quality of the bridge deck.
In the construction process of paving the epoxy asphalt concrete on the steel bridge deck in China, the epoxy resin waterproof bonding layer is generally adopted. The waterproof bonding layer has the advantages of good water seepage prevention effect, strong bonding force and high drawing strength. The second bridge of Changjiang river of Nanjing, Jiangsu Runyang, Tianjin Zhi bridge, Sutong bridge and the like in China all adopt the waterproof bonding layer form, and the pavement structure is not damaged and has good effect after the vehicle is started. Although manufacturers of hot-mix second-order epoxy resin adhesive layer oil exist in China, the construction workability is poor, and the epoxy resin A component and the epoxy resin B component are cured after being mixed for less than 5min at 40 ℃, so that the hot-mix second-order epoxy resin adhesive is not suitable for being used at high temperature in summer, and therefore a hot-mix second-order epoxy adhesive with excellent construction workability is urgently needed.
