Anxiang Cili expressway, abbreviated as "Anxiang Cili expressway", is the main part of the expressway network of Hunan Province, passing through Anxiang, Jinshi, Lixian, Linli, Shimen and Cili. The launch and construction of the anci expressway project will greatly improve the service level of the regional comprehensive transportation system, accelerate the construction of the economic circle around Dongting Lake in Northern Hunan, and promote the sustainable development of social economy in Northern Hunan. The construction of the Anzi expressway will also end the history of Shimen's lack of access to the expressway.

Anci Expressway starts from hejiayuan in Anxiang (connected with Changyue Expressway), passes through Jinshi City, Lixian County (intersecting Dongchang Expressway), yangban Township in linli (guojialing, Nanyue Village), Xiumei Town, shanban township (Niutou Village), Shimen Jiashan and jiepaiya, Miaoshi town of Cili County, and ends in Lingyang town of Cili County. The main line of the project is constructed according to the standard of four lane expressway. The design speed is 100 km / h and the subgrade width is 26 meters. The total length of the main line is 121.14 kilometers (including 98.63 kilometers in Changde City and 22.51 kilometers in Zhangjiajie City). It passes through Anxiang, Jinshi, Lixian, Linli, Shimen and Cili. It is a two-way four lane Expressway with a design speed of 100 kilometers / hour, an estimated investment of 10.25 billion yuan and a construction period of 3 years. In 2017, it is planned to complete an investment of 2.36 billion yuan.

The construction of three sections of subgrade surcharge of Anzi Cixi expressway was started at the same time, which was a battle of subgrade surcharge water bag preloading construction. The management team is stationed at the front, and the construction personnel of various subgrade construction sites who have been fighting for a long time meet in Anxiang. Peng Shengyun is responsible for the first bid, sun Yueping is responsible for the second bid, Ren Zhiguo is responsible for the third bid, Yang Hongwei and Ren Chunhua are responsible for the layout and installation of water pump pipes in the second bid and the third bid, Wang Huijun is responsible for material maintenance and living logistics, Peng Lixin and Peng Suo are responsible for water bag maintenance. Although the baseline road of this construction is long, there are many working points, the time is tight, and the task is heavy, the paving of water bags and the laying of water pipes and cables of water pumps have been progressing in parallel. The water bag is filled with water 24 hours a day, 24 hours a day. We have overcome the scorching heat in the day and the mosquito bites at night. The two shifts work in rotation. The first bid is the earliest to enter the site, and the completion of construction tasks is also the earliest; The third bid was also completed in time; The second target has the longest front and the largest workload. Under the coordination and deployment of the management team and the concerted efforts of everyone, the production progress was steadily promoted. The project department fully affirmed the work of the colleagues of suanda, and the leaders of the project department went to the construction site to express condolences to the brothers of suanda. The processing and mobilization of new water bags have been kept intensive and orderly. Since July 28, the impact of the epidemic has caused great trouble to the transportation of new water bags. Under such a severe situation, the people of suanda actively tried to find ways to find trucks through various channels, so that the water bags could be put into use on the site in time, meeting the construction progress and achieving the expected objectives.

The subgrade surcharge of anci expressway is another new work and masterpiece after the subgrade surcharge of Nanyi expressway, Xingshan expressway, Shantou Suei channel, Shantou Zhanjiang expressway, Niutianyang expressway, Guangzhou Nansha port, Xiamen Xiang'an, Zhanjiang Donglei expressway, Yangjiang port and Shantou Hutou mountain.

2018 is the first year that Wuhan suanda construction rubber and plastic products Co., Ltd. started the preloading of water bags for Subgrade stacking. After three years of experience, water bag preloading is more and more widely used in the preloading of subgrade soft foundation. As one of the service sectors of suanda, with the operation of subgrade surcharge water bag preloading service becoming more and more mature and stable, suanda's service road for National Road and bridge construction will become wider and broader.
