Background

In the bridge engineering construction process, when structures such as a capping beam and a bracket cast-in-situ 0# block are constructed by adopting a bracket method, a sand box is adopted to support the template, so that the template can be conveniently removed in later construction. When the precast beam is constructed, a sand box is often used as a temporary support, and when the precast beam is constructed in a structure such as a diaphragm plate, a wet joint, a pier top cast-in-situ section and the like, the box beam is dropped on a support to finish procedures such as unlocking the support. Therefore, the sand box is a common supporting structure and is widely applied to the bridge engineering construction process.

When the prior art is under construction, after the sand box is opened and closed, sand in the sand box flows out of the box body, and the cushion blocks descend along with the sand, so that space is reserved for dismantling the support and the precast beam to fall on the support. However, in the use process of the traditional sand box, sand in the sand box is difficult to recycle, and material waste is caused for construction. Meanwhile, because the sand flowing out speed in the sand box is uneven, uneven sedimentation is easy to occur, accidents such as sliding of the upper support of the frame body are easy to occur, and potential safety hazards are caused to construction.
