According to the technical scheme, the sand cylinder for bridge construction is characterized in that the sand cylinder comprises a cylinder body and a supporting piece arranged at the top of the cylinder body, a sand cavity is formed between the interior of the cylinder body and the supporting piece, and two sets of sealing doors sliding relatively are arranged at the bottom of the cylinder body; a two-way screw rod is jointly and spirally connected between the two groups of sealing doors, the two groups of sealing doors are provided with arch collapse structures capable of changing the arch collapse angle at the sand cavity, and the two groups of sealing doors are respectively provided with a top collapse structure which moves along with the sealing doors to collapse the sand in the sand cavity. According to the sand cylinder for bridge construction, the defect that gravels are difficult to take out after being flattened and caked can be overcome for a traditional sand cylinder structure, and the gravels are convenient to take out.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to a sand cylinder for bridge construction. Background technique [0002] The traditional bridge construction sand cylinder is such a structure, a cylinder used as the main body support, a support that can be lifted and lowered in the cylinder, the structural stability of the support is supported by the sand in the cylinder, and the support is Used to support concrete pieces. The use of sand cylinder support can avoid welding. When the support needs to be removed, a part of the sand and gravel is generally extracted from the small hole on the cylinder body, so that the support member goes down, so as to remove the support. This support structure is widely used and has a simple structure. [0003] Although the above-mentioned support structure is simple in structure, it is not a combination of various advantages. The main defects are: to ensure sufficient support reliab...
