Water stop structure of tidal mud flat reclamation area and water stop method conducted by using water stop structure

Abstract

The invention discloses a water stop structure of a tidal mud flat reclamation area and a water stop method conducted by using the water stop structure. The water stop structure comprises a steel tubelayer, a filling layer and a fixed layer which are defined sequentially from the edge of the tidal mud flat reclamation area to the direction away from the tidal mud flat reclamation area, wherein aclosed annular structure is formed around the tidal mud flat reclamation area, the bottom end of the steel tube layer penetrates through and is located below a riprap layer of the tidal mud flat reclamation area, the steel tube layer is defined by a plurality of steel tubes in sequence in a manner of mutual abutting, the filling layer is formed by tightly stacking a plurality of sand filling bags,and the fixed layer is formed by splicing a plurality of steel plates. According to the water stop structure of the tidal mud flat reclamation area and the water stop method conducted by using the water stop structure, by means of a three-layer structure from inside to outside, the bottom end of the steel tube layer penetrates through the riprap layer, the area of the riprap layer is effectivelyenclosed, and compared with traditional single-layer enclosure, the water stop structure has better effects, higher strength and higher tightness and effectively isolates erosion of a flow layer. In addition, during construction, the steel tube layer is driven first, followed by the fixed layer, and finally the filling layer is formed, so the laying efficiency is accelerated and a better laying effect is achieved.

Description

technical field [0001] The invention relates to a reclamation area of ​​tidal flats, in particular to a water-stopping structure of reclamation area of ​​tidal flats and a water-stopping method using the same. Background technique [0002] China's tidal flats are rich in resources and fertile soil, so the potential for building tidal flat reclamation areas to develop production in coastal tidal flats is quite huge. In the tidal flat reclamation area, the riprap layer is an important part of the reclamation foundation. However, the riprap layer has a large porosity, a hard texture, and a relatively loose structure. Therefore, for the construction of the reclamation area, it is first necessary to install a water-stop structure for waterproofing . [0003] The common water-stopping measure for seawall construction is to only use steel sheet piles for cofferdam, but on the one hand, because the steel sheet piles are relatively thin, when they are driven into the riprap layer, i...
