Description
Technical field
The invention belongs to Water Ecological Recovery technical fields, and in particular to a kind of novel ecological permeable dike and its construction method.
Background technique
A large amount of mill weir dams that block that the province mountain area such as Zhejiang, Fujian, Jiangxi is built at present may result in section generation downstream
Subtract dehydration, causes many water environmental problems such as aquatic animals and plants extinction, soil erosion.Meanwhile rural area production and living sewage, agricultural
Pollution of area source etc. causes mountain area middle and small river water pollution serious, and blocks mill weir dam and prevent the natural flowing of river water, also exacerbates
The deterioration of water pollution trend.In order to solve this problem, currently used measure includes: and builds more steps to block mill weir dam,
It forms limited water storage section, or is blocked in small hydropower station and add dewatering orifice, pipe etc. in mill weir dam and release ecological flow.However,
The new more steps of build block mill weir dam, and cost is larger, also only solves lower reache to a certain extent and subtracts dehydration problem；It adds
Although dewatering orifice blocks mill weir and can efficiently solve and subtract dehydration problem, exist release ecological flow facility easily by river garbage or
The disadvantages of artificial blocking, destruction.In addition, above-mentioned measure is difficult to cope with mountain area middle and small river water pollution issue, it is difficult to effectively
The reparation of ground realization Ecology.
Ecological permeable dam is a kind of weir pattern occurred in recent years.The structure is used to construct Plain River Network Areas earliest preposition
Library system is the effective engineering technology being evolved from traditional dam for administering water quality pollution of area source.It is stored before ensureing dam
While water, the downstream river sluicing of dam body tunneling boring seepage flow mode can be passed through；Dam body hole can grow some green plantss,
The polluter in adsorption and permeation water flow can be decomposed, effectively to realize mountain area middle and small river Water Ecological Recovery；It builds needed for the dam
Building stones be available locally, construction cost can be greatly reduced, have good economy.Common permeable dike include earth and rockfill dam,
Stone masonry dam and concrete dam etc., wherein native stone permeable dike is built up with weathering earth material or enrockment, dam body intensity is not high, stability

Although and concrete permeable dam stability and intensity are higher, and drainage channel need to specially be arranged, and comprehensive unit price is higher.
Cement sand and gravel is by the broken of the natural grit granulation in the riverbed near dam site or mountain area, dead meal or purchase
In the building stones such as building stones, a small amount of gelling agent is added, made of water mixes and stirs.When gelling agent volume is lower than 60kg/m3When, its surface is deposited
In certain gap, biocompatibility green cement can be selected can have so that dam surface pore can grow some green plantss
Effect decomposes the polluter in adsorption and permeation water flow, to realize mountain area middle and small river Water Ecological Recovery；Sand gravel in the material
Material is available locally, and the construction cost of ecological permeable dam can be greatly reduced, and economy is good；In addition, relative to rockfill, it is strong
Du Genggao.
How cement sand and gravel technology to be combined with the design of permeable dike, it is made both to can guarantee the ecological permeable dam
Intensity controls seepage discharge, and can simplify construction, reduce cost, is current urgent problem.
