Problems solved by technology

[0006] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a construction method for the steel structure of the main bridge: by starting the drive motor, the drive motor rotates through the linkage shaft and the feed cylinder to drive the spindle-shaped tank to rotate, start the stirring motor to run, and the stirring motor Drive the diversion stirring wheel to rotate, and transport the epoxy asphalt resin, mixture, and modified epoxy resin to the feeding pipes of the three bridge deck construction equipment through the delivery pump, and the epoxy asphalt resin or mixture or modified epoxy resin After the resin is diverted by the split stirring wheel, it enters the feeding barrel through the feed port, and then falls into the spindle-shaped tank. The rotating spindle-shaped tank transports the epoxy asphalt resin or the mixture or the modified ring through the conveying shear blade. The oxygen resin is continuously sheared, and the bridge deck construction equipment is hung on the carrier through t

Abstract

The invention discloses a main bridge steel structure construction method which comprises the following steps: sequentially paving an epoxy asphalt carbon fiber protective layer, an epoxy asphalt macadam shear layer, an epoxy asphalt concrete layer, a modified epoxy waterproof reinforcing layer and a modified epoxy macadam micro-surfacing treatment layer on a steel structure bridge deck to finish the construction of the steel structure bridge deck of a main bridge. The main bridge steel structure construction method is low in construction environment temperature requirement, normal-temperature construction and normal-temperature curing are achieved, construction conditions are easy to achieve, construction is easy and convenient, by laying the six layers of protection structures on the steel structure bridge deck, the steel structure bridge deck is high in fatigue resistance, resistant to high temperature and water damage, waterproof and corrosion-resistant, the service life of a main bridge is prolonged, meanwhile, raw materials of the six-layer protection structure are common, so that later maintenance is convenient, and cost is low; according to the construction method, laying construction is conducted through the bridge deck laying construction equipment, and the bridge deck laying construction equipment is high in automation degree, high in construction efficiency and low in construction cost.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a construction method for a steel structure of a main bridge. Background technique [0002] From the point of view of the entire physical structure of the bridge, the approach bridge abutment at both ends is the dividing point between the route and the abutment, and the part where the bridge hole crosses the main obstacle (such as a river) is called the main bridge. The existing bridge adopts steel structure as the main support structure , and it is necessary to construct the deck of the steel structure bridge to increase the physical performance of the bridge. [0003] When the existing bridge deck is being constructed, a large amount of asphalt mixed raw materials are needed, so several large tankers need to be used to transport the asphalt mixed raw materials from the production area of ​​the asphalt mixed raw materials. The cost is high. [0004] Therefore, how to solve t...
