(2) Project Overview
        Xiake Ferry (formerly known as Huangye Ancient Ferry) is one of the five ancient ferries in Lingling Ancient City. In history, it was a transportation hub for entering and leaving Lingling County and between Hunan and Guangxi. Nowadays, it is also one of the must pass road attractions for local residents and tourists from other places to travel between Liuzongyuan Scenic Area and Dongshan Scenic Area. It is a historical and cultural link connecting Dongshan and Xishan. This plan is based on“ Transportation as the main focus, integrating historical and cultural background; Design based on the concept. The entire floating bridge lies horizontally; Clear and secluded; On the Xiaoshui River, it showcases a rustic style. After the completion of the new bridge, it will continue to fulfill its historical mission and witness the wind, rain, dawn, dusk, and vicissitudes of the ancient county of Lingling as always. It will also become an eternal cultural sentiment in the hearts of the people of Lingling.
        Yongzhou City is located in the southern part of Hunan Province, at the confluence of the Xiao and Xiang rivers. The city is divided into two districts: Lingling and Lengshuitan. Among them, Lingling District is located in the southern part of Yongzhou City, at the intersection of Xiaoshui River and Xiangjiang River. The project is located on the Xiaoshui River between Liuzongyuan Scenic Area and Dongshan Scenic Area in Lingling District, Yongzhou City。

        The total length of the landscape floating bridge built in this project is 143 meters, the width is 4.1 meters, and the total area is 586.3 meters; The floating bridge connects to the Liuzongyuan scenic area with a distance of 10m; A 2.5m activity approach bridge, connected to the Dongshan Scenic Area end with 8m× One 2.5m activity approach bridge.
        Design scope: The main structural type of the floating bridge is steel boat body+steel structure platform+aluminum alloy railing. The floating bridge is composed of steel structural sections connected together, with a standard length of 10m and a width of 4m. The lower part of the structural section consists of two steel boats, and the upper part is equipped with railings on the sides. The surface of the structural section is covered with anti-corrosion wooden boards. The dimensions of the main steel boat body (Loa× B× D) are: 11× 2× 1.1m、11× 2.2× 1.1m. Each 10m× The 4m structural section consists of two 10m frames; It is composed of 2m steel structure frame connection. The side longitudinal beam of the steel structure frame is 16a # channel steel, the side longitudinal beam of the middle connection is 16a # channel steel, the end cross beam is 16a # channel steel, the cross brace is 10 # channel steel, and the slant support is 63× 4 angle steel. The steel frame is subjected to anti-corrosion treatment as a whole. The railing is made of aluminum alloy and the column is 120× 120× 4mm aluminum alloy square tube and 120× 80× 3mm aluminum alloy square tube, with handrails of 100× 50× 3mm aluminum alloy square tube, horizontal bar made of 100× 50× 3mm aluminum alloy square tube and 20× 20× Composed of 2mm aluminum alloy grids, the railing is made in a wooden like form and painted with colored paint on the surface.
        The floating bridge connecting to the shore and the movable approach bridge are 10m× 2.5m、8m× 2.5m， Aluminum alloy structure, the style of the handrails on both sides of the approach bridge is the same as that of the floating bridge railings.
        The entire floating bridge is in a straight line shape, satisfying the travel needs of local people and the viewing experience of tourists. Standing under the long corridor and looking out over the Xiaoshui River from afar, it creates a picturesque scene; On the blue waves of the boat, people swim in the painting; A poetic and picturesque scene arises spontaneously.

Navigation and dismantling
        Due to the high frequency of fishing boats and navigation on the Xiaoshui River, the design of this plan fully considers the navigation requirements of local fishing boats and other small boats. By increasing the depth of the load-bearing hull, the freeboard of the hull is improved, thereby increasing the height between the floating bridge surface and the water surface. This design height is suitable for slow navigation of small boats with a total height not exceeding 0.8 meters and a width not exceeding 3 meters.

(3) Project Features
        The entire floating bridge is in a straight line shape, satisfying the travel needs of local people and the viewing experience of tourists, achieving the integration of floating bridge and cultural landscape, and forming a rich sensory experience.
        The use of materials with an antique atmosphere further showcases the culture and urban image of Lingling District.
