Considering the disadvantages of caisson, Highway Corporation of Anhui province put forward a brand new foundation style—Rootstalk Foundation, a research group was set up and a national patent was applied. Its construction process are: obligate jack hole in the caisson, jacked the prefabricate rootstalkinto the soil after the caisson sank to the design elevation, assuring that the rootstalks are fixed with the caisson then a root-simulated foundation is completed. The load capacity of ambient soil is greatly activated because of the penetration, compression and stress pervasion of the jacked rootstalk.

为此，安徽省高速公路总公司根式基础课题组提出一种全新的基础形式——根式基础，并申请了国家专利，它是采用沉井预留顶推孔，待沉井下沉到设计标高后在土层中顶推预制的根键，在保证根键与沉井的固结后形成一种仿生基础，由于顶推根键的挤密和应力扩散作用充分调动了基础周边土体的承载潜力，使得基础底部得以"卸载"，其承载力得以大大提高。

From the construction aspect, the difficulties of this engineering consists highness of the water table, the inequality of distributing of the stratum, and how to ensure that the six sections open caisson go down successfully and the appearance looks beautiful under the situation of intermixing powder gushing stake, filling clay and so on. Then this paper narrates the selecting of construction scheme, the groundsill dispose and execution technics of the open caisson, the arrangement of construction order during the going down course, the taphole method and the setting and effect of the block sinking board.
