Embodiment Construction
[0031] see figure 1 , figure 2 and image 3 In the present embodiment, four thin-walled piers are arranged on the concrete cap 1 in a rectangular distribution, and the anti-ship facilities are arranged on the concrete cap 1 and one on both sides of the limbs thin-walled piers. The steel concrete column is used as the anti-collision pier 3, and "D" type rubber fenders 4 are respectively arranged on the outer walls of the anti-collision pier 3 and the thin-walled pier 2; Beams 5 are connected horizontally.
[0032] In specific implementation, the corresponding structural settings also include:
[0033] Such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the horizontal beam 5 is a section steel assembly, which is a triangular structure formed by a pair of horizontal channel steels 51 arranged in a "V" shape and a horizontal I-beam 52 connected between the pair of horizontal channel steels 51; 52 are also jointly connected between two thin-walled bridge pier...

The invention discloses a four-leg thin-wall pier facility against ship collision and a construction method thereof. A four-leg thin-wall pier is formed in a way that four thin wall piers are rectangularly distributed on a concrete bearing platform. The four-leg thin-wall pier facility against ship collision is characterized in that steel reinforced concrete upright posts are respectively arranged at the two sides of the four-leg thin-wall pier on the concrete bearing platform as crash bearers, the outer side walls of the crash bearers and the thin-wall piers are respectively provided with D-shaped rubber fenders, and the top ends of the crash bears and the thin-wall piers are horizontally connected by installing horizontal beams. The four-leg thin-wall pier facility against ship collision provided by the invention is simple in structure, low in cost and small in occupied waterway space, and accords with a navigation span requirement; furthermore, various loading states of ships can be dealt in various water level conditions, therefore the ships cannot directly strike the piers, and the anti-collision fenders are good in energy absorption and energy consumption effects.
Description
technical field [0001] The invention relates to a pier anti-ship collision facility and a construction method thereof, and more particularly relates to an anti-ship collision facility and a construction method for a thin-walled pier with four limbs. Background technique [0002] With the continuous development of national transportation, a large number of bridges across rivers and rivers have been built, and the volume of ship transportation has also increased rapidly. The probability of ships colliding with bridge piers has increased significantly. Therefore, how to effectively protect bridge piers is particularly important. Traditional protection methods for bridge piers include artificial islands, protective piles, and anti-collision casings, etc., but the existing forms are complex in structure, difficult in construction, high in project cost, cumbersome in maintenance and replacement, occupy a large space in the river, and have limited anti-collision functions. Limitati...
