Description
Technical field
The invention belongs to Hydraulic and Hydro-Power Engineering technical field, and in particular to dyke and dyke structure of a kind of band from discharge structure
Construction method.
Background technology
Dyke building is to resist a kind of flood measure, therefore it is widely deployed and prevents in water conservancy
In big vast engineering.There are various hidden danger such as poor levee body condition, levee body material and construction quality difference in China's existing dike, dyke is in dash
During, usually cause dyke to go wrong because internal penetration pressure is excessive.
The method for reducing dyke internal penetration pressure is mainly " upper anti-lower row ", and dyke upstream face is mainly included at present,
Levee foundation sets cut-pff wall or in bank slope sets fluid-tight geomembrane reduces saturation；Core-wall is set in the middle part of dyke to reduce
Internal penetration pressure；And in back side loaded filter or gutter are set reduce the saturation inside dyke.But, dyke is long
Degree is generally tens kms, to arrange that huge these leakage preventing structure workloads, the substantial amounts of manpower and materials of consuming, construction are difficult in dyke
Degree is big, and protection of either any leakage preventing structure to dyke latter half is smaller, because dyke latter half still have compared with
Saturation high, it is possible to produce piping in dyke latter half, come down equivalent risk.Therefore, it is necessary to design a kind of knot
Dyke of the band that structure is simple, low cost, easy construction, drainage effect are good from discharge structure.
