Pinyin and meaning of pier

Pierre's pinyin is qiáo and dūn, which refers to the pier under the bridge.

Foundation explanation: the pier under the bridge plays a bearing role and is made of stone or concrete.

Detailed explanation: The piers supporting the bridge body under the bridge are mostly stone or reinforced concrete. Engineer in Du Pengcheng: "On both sides of this big river, there stands a tall pier."

In this case, the design of the collapse of the anti-collision pier is particularly important.

Architectural features:

The pier is mainly composed of a top cap and a pier body. Abutment is mainly composed of top cap and abutment body. The function of the top cap is to transfer the large and concentrated force from the bridge span support to the pier and abutment in a decentralized and symmetrical way. Therefore, the top cover should be made of high-strength materials, generally using reinforced concrete of not less than grade 200, with a thickness of not less than 40 cm. In addition, the top hat must have a larger plane size to provide the necessary working face for beam erection and maintenance.

Pier is the main structure supporting the bridge span, which not only bears all the loads from the bridge span structure, but also directly bears various loads such as earth pressure, water impact force, ice pressure and ship impact force, so the pier has sufficient strength, stiffness and stability.
