Problems solved by technology

[0003] The object of the present invention is to provide an energy-absorbing pier anti-collision clothing and its construction method. The anti-collision clothing has strong buffering and energy-absorbing functions, and the components are freely assembled and assembled, which can improve the currently used rigid and flexible anti-collision clothing. The lack of safety and reliability of collision facilities plays an important role in ensuring the safety of bridge structures, the safety of traffic drivers and passengers, and reducing property losses of vehicles and ships.

Embodiment 1

[0025] Depend on Figure 1-Figure 2 The shown energy-absorbing pier anti-collision clothing includes a honeycomb intermediate reinforcing body 2 arranged around the outer circumference of the bridge pier 1 and an outsourcing steel plate 4 fixed around the outer circumference of the honeycomb intermediate reinforcing body 2, and the two outer covering steel plates 4 The end is closed, and the outer surface of the outsourcing steel plate is provided with a reflective mark, which is not shown in the figure.

[0026] The honeycomb-type intermediate reinforcement 2 is composed of several hollow cylinders 3 that are in the same extension direction as the pier 1 and fixed together in a honeycomb structure. The honeycomb structure is a honeycomb body composed of hollow cylinders arranged in sequence toward the outer circumference. A single hollow column The body and its peripheral hollow cylinder are overlapped or contacted and fixedly connected. The cross section of the honeycomb bod...

Embodiment 2

[0031] Depend on Figure 1-Figure 2The construction method of the energy-absorbing pier anti-collision clothing shown is the method of constructing the energy-absorbing pier anti-collision clothing described in Example 1, which includes the following steps: (1) according to the construction drawing of the pier 1, the construction of the pier 1 construction, and set the embedded parts 7 on the pier 1, (2) Make the hollow cylinder 3: each hollow cylinder 3 is made of a regular hexagonal tube with a side length of 30cm in cross section ( That is, a regular hexagonal steel pipe prism), the height of the hollow cylinder 3 is 300cm, and the height of the hollow cylinder 3 is determined according to the impact height of the vehicle (overpass land pier) and ship (water pier); the thickness of the steel plate of the hollow cylinder 3 Determined according to calculation and structure; the bottom of the hollow cylinder 3 is welded and sealed with a corresponding regular hexagonal steel p...

Abstract

The invention discloses energy-absorbing pier collision avoiding clothes and a building method thereof. The energy-absorbing pier collision avoiding clothes comprises a honeycomb type medium reinforced body arranged at the peripheral ring of a pier and an exterior steel plate arranged around the peripheral ring of the honeycomb type medium reinforced body; an energy absorbing material layer is arranged between the honeycomb type medium reinforced body and the pier; the honeycomb type medium reinforced body is formed by a plurality of hollow pillar bodies consistent with the pier in the extending direction; the bottom ends of the hollow pillar bodies are closed; adjacent hollow pillar bodies are fixedly connected; energy absorbing materials are arranged in bee holes of the honeycomb type medium reinforced body; the pier is provided with a precast part and is fixedly connected with the honeycomb type medium reinforced body by the precast part. The building method of the energy-absorbing pier collision avoiding clothes is an implementation method based on the energy-absorbing pier collision avoiding clothes. The energy-absorbing pier collision avoiding clothes and the building method have higher buffering and energy-absorbing actions.

Description

technical field [0001] The invention belongs to the field of bridge pier anti-collision technology, and in particular relates to an energy-absorbing bridge pier anti-collision clothing and a construction method thereof. Background technique [0002] Since the accidents of sailing ships or vehicles driving under the bridge colliding with the piers often occur, causing great harm to the bridge structure, the life safety of traffic drivers and passengers, and the property of vehicles and ships. An important way to protect the safety of bridge structures is to set up anti-collision facilities for bridge piers. Bridge pier anti-collision facilities are generally located on relevant piers with navigation requirements or in the three-dimensional traffic of cities and expressways, which can be used for safe diversion, warning, collision prevention and buffering in the event of collisions, while absorbing and reducing the impact of collisions. Bridge pier anti-collision facilities ca...
