specific Embodiment approach 1

[0009] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, a bridge anti-drift ice impact device described in this embodiment includes a base 5, several anti-collision units and several reset assemblies 3, the base 5 is set on the outer wall of the pier 6 through a plurality of expansion bolts 4 Two adjacent anti-collision units are connected by a reset assembly 3 , several anti-collision units and several reset assemblies 3 form a closed frame, and the closed frame is sleeved on the base 5 .

specific Embodiment approach 2

[0010] Specific implementation mode two: combination figure 1 and figure 2 Describe this embodiment, each of the anti-collision units of a bridge anti-drift ice impact device in this embodiment includes a corrugated folded steel plate 1 and a shock absorbing block assembly 2, and one end of the shock absorbing block assembly 2 is a corrugated folded steel plate 1, the other end of the shock-absorbing block assembly 2 is connected to the base 5. In this way, other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0011] Specific implementation mode three: combination figure 1 , Figure 7 to Figure 9 To illustrate this embodiment, the shock absorber assembly 2 of a bridge drift ice prevention device described in this embodiment includes two energy-dissipating and shock-absorbing rubber blocks 2-1, and the two energy-dissipating and shock-absorbing rubber blocks 2-1 are parallel to each other. To set up, one end of each energy-dissipating and shock-absorbing rubber block 2-1 is connected to the inner surface of the corrugated folded steel plate 1, and the other end of each energy-dissipating and shock-absorbing rubber block 2-1 is connected to the base 5.

Abstract

The invention relates to a floating ice impact preventing device, in particular to a floating ice impact preventing device for a bridge. The problem that no special floating ice impact preventing device exists at present is solved. The floating ice impact preventing device for the bridge comprises a base, a plurality of impact preventing units and a plurality of reset components, the base is arranged on the outer side wall of a pier through a plurality of expansion bolts in a sleeved mode, every two adjacent impact preventing units are connected through one reset component, a sealed frame is formed by the impact preventing units and the reset components, and the sealed frame is arranged on the base in a sleeved mode. The floating ice impact preventing device is used for the field of bridge construction.

Description

technical field [0001] The invention relates to an anti-drift ice impact device, in particular to a bridge anti-drift ice impact device, which belongs to the construction field. Background technique [0002] Bridges are important buildings in the production and life of human society, and are an important part of transportation infrastructure, especially bridges in some key positions, which are often called lifeline projects. Therefore, ensuring the safety of bridges during their service life is an important task and mission for bridge scientists and technicians. [0003] Our country is a country with many ice damages. The rivers, lakes and seas north of 25 degrees north latitude have ice conditions in winter. The places where ice often occurs every year are mainly in the 16 provinces north of 30 degrees north latitude and the northern part of the Bohai Sea and the Yellow Sea. Serious ice conditions exist in the Yellow River, Liaohe River, Songhua River, Heilongjiang, Nenji...
