A stone bridge is a bridge made of stone. There are stone beam bridges and stone arch bridges, both of which have a long history. The famous stone girder bridges in Chinese history include Luoyang Bridge and Lugou Bridge. Due to the poor bending resistance of stone girders, they can only be used in pedestrian bridges or culverts. Stone arch bridges have not only had brilliant achievements in history, but also have high reference value for bridge construction today.
As the name suggests, the landscape bridge and arch bridge are bridges made of stone. There are stone girder bridges and stone arch bridges. They have a long history. The famous stone girder bridges in Chinese history include Luoyang Bridge and Hudu Bridge. Due to the poor bending resistance of stone beams, they can only be used in footbridges or culverts. The stone-carved arch bridge has not only had brilliant achievements in history, but also plays a certain role in modern railway and highway bridges.
This stone-carved arch bridge is custom made of granite stone. The arch bridge is beautiful in shape, simple and generous, with rounded curves, full of dynamic sense, and parabolic shape. The entire stone arch bridge is divided into two parts, namely the railing part and the bridge deck part.
Let’s talk about the bridge deck first. As the name suggests, the entire stone arch bridge is designed according to the shape of the arch. The arch is also bow-shaped, so the entire bridge deck is in a natural arc shape during processing. Generally, the stone arch bridge part needs to be integrally formed. , so relatively large stones are required for processing. If the stone bridge is relatively large, the main bayonet and wedge must be used during the splicing process. The upper part of the bridge deck adopts a stepped structure, with three steps on the left and right, each step is 5 cm high and 30 cm wide, and the step surface is parallel to the water surface below. The sides of the bridge deck are processed with circular relief lines, with simple and elegant patterns.
As for the railing, we can see that the post of the railing is always perpendicular to the water surface below, on the curved bridge, so the bottom of the entire post, the ground load, is curved and curved. Therefore, the difficulty of design and processing here will be much higher than that of the flat concrete floor. The railings of the stone arch bridge are divided into left and right sides, and the left and right sides are symmetrical. In terms of structure, the left and right door drum stones are used, and the middle part is a three-sided hollowed-out guardrail. In terms of our story, the shape of the door drum is simply processed with thread carving. As for the railings, a special-shaped cutting hole is cut in the middle, which can be completed with water jets and laser engraving machines. This shape is a bit like the shape of a candy jar during the Chinese New Year. The stigma is in the shape of a car stone. It is worth mentioning that the looking pole of this railing is made of circular arc, so the whole stone railing looks very smooth. There are not many carving techniques on this stone arch bridge, and it can only show some simple and basic stone carving culture, but it is simple and not monotonous, and there are still many aesthetic feelings worthy of our appreciation.
