Tingbu and jumping pier are also called. Although they are the most primitive forms of water-crossing and have been replaced by new technologies, they can still be used in gardens to give full play to the interesting cross-water scenery, so that people can walk in Tingbu with countless close-water intimacy of clean-flowing fish under their feet. Tingbu is the most suitable surface for small-span shoal streams. There is also a combination of rolling dam body set up over the dam step, but pay attention to safety.
Beams and single-timber bridges are the most primitive bridges across water. It can still be used on the surface of small rivers and streams in gardens with small widths. Even if the width of the water surface is not deep, piers can be built to form multi-span bridges. Beam bridge is smooth and easy to walk and traffic . In the design of water scene, beam bridge can not only arrange traffic, but also combine with the surrounding environment to form a poetic and picturesque artistic conception, which is interesting.
Arch coupon is the creation of large-span engineering with human stone. It has been used in our country for a long time. Arch bridges are of various forms, from single arch, three arch to continuous multi-arch, which are convenient for the selection of gardens in different environments. Functionally, they are used to the requirements of above and below navigation. Arch bridges have more unique landscaping effect in gardens. Therefore, there is a description of "Changhong sleeping in a circle of shadows". Such as the Jade Belt Bridge and the Seventeen-hole Bridge in Beijing. The Jade Belt Bridge is the only high arch stone bridge on the Xidi. Its arch is tall and thin. It is just like a jade belt dancing across the water. It has a messy shape and exquisite structure, reflecting a graceful shadow on the water.
Floating bridge is a simple and temporary method for wide water surface. It can avoid engineering measures such as pier foundation and so on. It only uses boat or buoy instead of girder slab on pier and cable to fix it to become a viable pontoon bridge. In the design of water scenery, it has many effects, but its main point is not to arrange traffic. Because it is firm and unstable, people have the tendency of shaking and chaos on it, giving people a feeling of uneasiness. Using the unstable factors of floating bridge, it can make a strong contrast with the static state of water, and can stimulate people to take risks and be active and enterprising.
In the deep stream of rapids, high mountains and canyons, there is no condition to build piers under bridges. For example, in the southwest of China, suspension bridges are most suitable. The suspension bridge has beautiful curves and gives people a sense of lightness. Standing on the bridge, you can see both from afar and from afar. With the development of science and technology in our country, more and more lightweight suspension bridges with beautiful curves will appear in the design of water scenery in the future.
Pavilion Bridge and Corridor Bridge
This kind of bridge, which has both traffic effect and recreational function and landscaping effect, is very suitable for garden requirements. For example, on the West embankment of the Summer Palace in Beijing, Pavilion bridges such as Youfeng Bridge, Jingqiao Bridge, Lianqiao Bridge and Greenwillow Bridge have been built. These bridges play a resting effect on the long dike tour line, breaking the horizontal line composition of the upper dike in the long view, having the effect of comparing the landscape and dividing the water level . The flower bridge of Qixingyan, Guilin, is the first scene to be built at the entrance of the park. The Wuting Bridge on the Slender West Lake in Yangzhou is the main view on the long axis of the Slender West Lake.
