Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, an anti-cracking bridge structure includes a concrete bridge body 1 and a steel cylinder 2 arranged in the concrete bridge body 1; the steel cylinder 2 is a rectangular hollow steel cylinder, the two ends of the steel cylinder 2 are closed, and the middle part of the steel cylinder 2 is A solid body 3, the top of the solid body 3 is provided with a water inlet hole 4 extending vertically downward, and the side of the solid body 3 is provided with a water outlet hole 5 extending horizontally and communicating with the water inlet hole 4 and the hollow part of the steel cylinder 2; The upper end of the water inlet hole 4 is provided with a threaded plug 6; the hollow part of the steel cylinder 2 is filled with water 7.

[0027] The installation process of the present invention is as follows:

[0028] Water 7 is injected into the steel cylinder 2 through the water inlet hole 4 , and then the water inlet hole 4 is blocked by a scre...

Embodiment 2

[0030] Such as figure 1 As shown, this embodiment is based on Embodiment 1, and the inner upper surface of the steel cylinder 2 is provided with an accommodation groove 8 , and the height of the water surface is lower than the accommodation groove 8 .

Embodiment 3

[0032] Such as figure 2 As shown, on the basis of any one of the above-mentioned embodiments, this embodiment also includes a protective cover 9, the protective cover 9 is disc-shaped, and a plurality of connecting blocks 10 are arranged on the outer circular surface of the protective cover 9; the solid The top of the body 3 is provided with a circular groove 11, and the water inlet 4 extends vertically downward from the bottom of the circular groove 11; the circular groove 11 is compatible with the protective cover 9, and the surroundings of the circular groove 11 are provided with accommodating connection The accommodating opening 12 of the block 10 is welded to the connecting block 10 and the accommodating opening 12 .

Abstract

The invention discloses a cracking-preventing bridge structure. The cracking-preventing bridge structure comprises a concrete bridge body and a steel cylinder arranged in the concrete bridge body. The steel cylinder is rectangular and hollow, the two ends of the steel cylinder are closed, the middle of the steel cylinder is a solid, the top of the solid is provided with a water inlet hole vertically extending downwards, the side face of the solid is provided with a water outlet hole which extends horizontally and is communicated with the water inlet hole and the hollow part of the steel cylinder at the same time, the upper end of the water inlet hole is provided with a thread blocking plug, and the hollow part of the steel cylinder is filled with water. The steel cylinder is filled with water, and due to the fact that the specific heat capacity of water is large, the difference between the temperature inside concrete and the temperature outside the concrete can be reduced very well, the temperature inside the concrete and the temperature outside the concrete is made to reach the balance state as much as possible, and the concrete is effectively prevented from cracking when the difference between the temperature inside concrete inside and the temperature outside the concrete is excessively large.

Description

technical field [0001] The invention relates to the field of construction, in particular to a bridge structure. Background technique [0002] Existing bridges are mostly constructed of concrete. [0003] In areas with a large temperature difference between day and night, it will cause a large temperature difference between the inside and outside of the concrete. After the bridge has been in operation for a long time, the large temperature difference inside the concrete will cause the concrete to crack. Because the bridge is subjected to irregular loads for a long time, the cracks in the concrete will continue to grow, which greatly affects the safety of the bridge. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a crack-proof bridge structure. [0005] The object of the present invention is achieved through the following technical solutions: [0006] An anti-cracking bridge structure, co...
