Introduction

The middle supporting structure of a multi-span bridge is called a pier. Bridge Pier Protection are divided into solid piers, column piers, and bent piers and so on. According to the plane shape, it can be divided into rectangular pier, tip pier, circular pier and so on. The materials of bridge piers can be made of wood, stone, concrete, reinforced concrete, steel and so on.

The pier is mainly composed of top cap and pier body. The abutment is mainly composed of top hat and abutment. The function of the top cap is to transmit the large and concentrated force from the bridge span support to the pier body and platform body in a scattered and symmetrical manner. Therefore, the top cap should be built with high strength materials, generally not less than 200 grade reinforced concrete buildings, and the thickness is not less than 40 cm. In addition, the top cap must have a larger plane size to provide the necessary working face for the construction and maintenance of the beam. 

The pier body and abutment are the main structures supporting the bridge span, which not only bear all the loads from the bridge span structure, but also directly bear many kinds of loads, such as earth pressure, water flow impact force, ice pressure, ship impact force and so on. therefore, the pier body and abutment have sufficient strength, stiffness and stability.

Bridge protection products are usually selected square fender, installed at the side of bridge, to alleviate the impact of the ship docked on the bridge. The Bridge pier protection may be square, rectangular or other shaped products.

Application

Plastic fender is a new type of water bank collision protection product used in the field of port wharf, embankment, ship edge and pier protection, which is used to prevent or avoid damage caused by collision to ships, wharf, embankment and pier. Application fields are as follows:

Port wharf protection: replace traditional wooden and rubber fender, and use it as anti-collision pile and protection system for inland river and coastal ports. Bridge pier and river protection: used as a collision barrier for protecting bridge piers and rivers. The impact force is unloaded by elastic buffering and extremely low friction coefficient to ensure maximum protection of bridge piers and vessels.

Embankment, retaining wall: good weather resistance, no freezing cracking, long service life, high corrosion resistance.

Floating row and floating wood: It can be used as floating material on the shore. It can float on the surface of the water. Length can be customized, single or multiple rows, and the collision force can be used for collision avoidance.

Protection of reclamation, soft soil and marsh construction of reclamation project: good weather resistance, no cracking due to freezing, long service life and high anti-corrosion.

Protective piles and offshore working platforms: excellent anti-corrosion performance, no decay, no rust, no pollution to seawater.

Protection of the ship lock entrance and diversion wall: low friction coefficient, good impact resistance, corrosion resistance and long service life. Pier corner protection: use the ground rail and the dock retaining edge, and use it with the dock fender. Density during 0.7-0.9, can float in water, density also can be customized according to needs.
