Background
At present, the construction industry is changing to the direction of standardization, quality and efficiency, along with the continuous improvement of the design time speed of the high-speed railway, the requirements of construction quality are increasingly strict, new tools and new tools are continuously adopted, the labor efficiency is improved, the labor force is saved, and the development trend of the construction industry in the future is realized. At present, domestic labor is seriously aged, the ages of staff are too large, heavy physical labor is difficult to conduct, and the risk coefficient is large. In traditional bridge construction, the anti-falling stop block should be placed in the girder cavity of the box girder in advance and reach the designated position along with the erection of the box girder, but in actual construction, the anti-falling stop block usually needs to be dumped in later period due to the fact that the anti-falling stop block enters the field untimely, the erection period of the box girder is compact and the like. At present, three common transportation modes are adopted in a construction site, one is to manually transport the bridge head (bridge abutment) into a box girder, transport the bridge head (bridge abutment) to a designated position one by using a trolley, and then manually transport the bridge head to the pier top for installation. The method has extremely low work efficiency, is time-consuming and labor-consuming, and requires more labor cost. If an oversized long bridge is encountered, the transportation of a plurality of kilometers is very difficult; in addition, the continuous Liang Liangqiang structure is complex, and the trolley cannot pass through, so that the transportation difficulty is greatly increased. The other method is to vertically hoist the anti-falling stop block from the pier bottom to the pier top, and although the method can save manpower, the crane needs to be erected and the crane needs to take up legs in a large amount of time, the construction efficiency is extremely low, the cost of the crane for a shift is higher, and the method is extremely uneconomical. The third method is that on the beam surface, a hoist is used to transport the anti-drop stop block from the bridge pier end to the hanging basket, and then the anti-drop stop block is manually and secondarily transported to the groove of the bridge pier, but the method cannot be constructed after the construction of the beam surface protective wall, the A wall and the B wall is completed. In addition, because the anti-falling stop block structure is irregular and the weight is large, once the situation that the number of the anti-falling stop blocks entering the field is not matched with the erection progress of the box girder occurs, the engineering progress can be influenced, and therefore, the safe, efficient and economical transportation of the anti-falling stop block to the pier top is very important. The conventional shipping methods are time-consuming, labor-consuming, high in shipping cost, slow in progress, high in unsafe risk and limited.
