Problems solved by technology

De-icing and ice-breaking methods require more energy or manpower; although the coating method can effectively reduce the bond strength between ice and the surface of the structure and reduce the vertical ice load between the ice and the structure, the coating The layer is easily damaged and fails, and the horizontal ice load cannot be reduced
The slope structure has a good effect on reducing the horizontal ice load, but it cannot reduce the vertical ice load; the buffer device is suitable for both the structure to be built and the built structure, and has good applicability, but the existing The structure of the buffer device is relatively complicated, and the construction is relatively cumbersome, and the buffering effect on the horizontal ice load is mainly considered

Embodiment 1

[0043] like Figure 1-3 As shown, a protection unit, protection unit 1, is used to reduce ice loads acting on bridge piers and / or pile structures, and protection unit 1 includes:

[0044] At least one upper compartment 2, after the protection unit is inflated, is used to bear the ice load acting on the surface of the protection unit;

[0045] At least one of the lower compartments 3 connected to the lower end of the upper compartment 2, after the protection unit is inflated, part of the protection unit 1 can be placed in water for the counterweight of the protection unit 1.

[0046] Specifically, fine sand and water are used as the counterweight material in the lower compartment 3 .

[0047] Specifically, when the upper cabin 2 and the lower cabin 3 are arranged as separate bodies, the materials of the upper cabin 2 and the lower cabin 3 are all butadiene rubber with strong elasticity, wear resistance and cold resistance.

Embodiment 2

[0049] like Figure 1-3 As shown, on the basis of the structure of Embodiment 1, further, the upper cabin 2 and the lower cabin 3 can be integrally formed, and the part connecting the upper cabin 2 and the lower cabin 3 is the cabin partition layer 4 .

[0050] Specifically, when the upper cabin 2 and the lower cabin 3 are integrally arranged, the upper cabin 2, the lower cabin 3 and the cabin partition layer 4 are made of butadiene rubber with strong elasticity, wear resistance and cold resistance.

Embodiment 3

[0052] like Figure 1-3 As shown, on the basis of the structures of Embodiment 1 to Embodiment 2, further, the upper cabin 2 is provided with a multi-layer horizontal wire drawing structure 5, which is used for after the upper cabin 2 is inflated, the upper cabin The form of 2 is a thin plate form.

[0053] Specifically, the wire drawing structure 5 is a high-strength fiber layer.

Abstract

The invention relates to an air cushion type ice-resistant protection structure for a wading pier column, a protection unit and a construction method of the air cushion type ice-resistant protection structure. A buffer deformation zone with high toughness is constructed between the pier column and an ice surface, so that ice expansive force and ice thrust caused by peripheral uneven expansive force can be effectively weakened; the vertical acting force generated by lifting of the ice surface driven by fluctuation of the water level can be weakened, and the device is particularly suitable for reducing ice-resistant protection of the pier stud in the still water area. In addition, the modular unit construction mode of the protective structure is convenient to construct and maintain, and the practicability is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of ice damage prevention and control in water conservancy projects, in particular to an air-cushion type anti-icing protection structure, a protection unit and a construction method for wading piers and columns. Background technique [0002] For wading structures in cold regions, ice load is usually a key controlled environmental load, which is very important for structural optimization design and safe operation and maintenance. The research and development of anti-icing protection methods, devices or structures for eliminating or reducing the influence of ice loads has always been a hot and difficult point in the research field of engineering ice damage prevention technology. [0003] For rivers, channels, sluice vertical banks, bridge piers, wharf piles, offshore platform columns and other pile-type structures in cold waters, the ice loads suffered during the ice age can be divided into horizontal ice load...
