Description

TECHNICAL FIELD

[0001] The utility model relates to a sea dike structure technical field, concretely is a soft foundation embankment structure of dike body space fusion municipal function. BACKGROUND

[0002] The sea dike engineering is the first line of defense against typhoon storm surge disaster, is the important infrastructure in coastal areas, and the land resources are scarce in the relatively developed coastal areas. The silt coast of China is widely distributed, especially the soft foundation in the east coast of Zhejiang is deep, the land for the implementation of the sea dike engineering is limited, and the technical requirement is high. The traditional soft foundation embankment is mostly large-section gentle slope earth-rock dike, and the land area is huge, and the dike body range plane and space cannot be used for other purposes due to the protection demand of water conservancy engineering management. Since the beginning of the 21st century, the concrete frame sea dike has been built in the east coast of Zhejiang, which better solves the problem of large land area of earth-rock dike on soft foundation, but the built sea dike is mostly open concrete frame type, or the empty box of dike body is closed for the convenience of management, but the inner slope is provided with closed soil, and the dike body space cannot be utilized.

[0003] On the deep soft foundation of coastal beach, the lack of foundation bearing capacity seriously restricts the construction method, and the newly built sea dike is not protected by the old dike, so the construction site needs to build cofferdams or tide construction. The traditional solution is to treat the foundation soil by using vacuum preloading method, and the cofferdam is formed by layered filling earth-rock on the foundation soil, the construction period is long, and the cofferdam section is large to occupy a large range of land, so the treatment is extremely difficult. In addition, the dike body of the soft foundation reinforced concrete frame dike usually adopts cast-in-place pile support, and the negative friction caused by the settlement of the foundation soil around the pile due to backfilling behind the dike is large, which has adverse effects on the stability of the frame dike.
