Abstract
The present invention provides a kind of irrigation canals and ditches in sponge city, mainly includes the heavy mud groove of sawtooth pattern, half deep mud platform, slag net, buffering gate and Man Shuipo.The heavy mud groove of sawtooth pattern has multiple and scattering device in the bottom of trench of irrigation canals and ditches and keeps recess depths away from water (flow) direction；Half deep mud platform is had multiple and is staggered on the right and left upper half wall of irrigation canals and ditches with semiellipse column gap shape；Buffering gate is stood using rotatable turbine in irrigation canals and ditches water outlet end, and laterally neat irrigation canals and ditches width setting and height only account for the half of trench depth；3-5 blade is evenly distributed in the shaft of turbine, neat half ditch depth of water flow can push blade drainage；The slope Man Shui is located at the top of the nearly water outlet end unilateral side wall of irrigation canals and ditches and its neighbouring soil, absolute altitude are lower than neighbouring earth's surface, and along water (flow) direction absolute altitude lifting step by step, and slag net is stood on before the slope Man Shui in irrigation canals and ditches.Body refuse can deposit on heavy mud groove, heavy mud platform and the slope Man Shui；Water flow can also accumulate when smaller and slow release.
Description
Technical field
The present invention relates to a kind of irrigation canals and ditches in sponge city, be while ensureing drain function, be attached with water purification step by step with
The irrigation canals and ditches of water storage slow-release function.
Background technique
The function of irrigation canals and ditches mainly conveys water flow, therefore effectively Quick drainage is its major function.With sponge city
Propulsion and pay attention to day by day to water environment Ecology, the drainage ditch for having water purification function will be provided with good Ecological Effect
Benefit.In actual life, due to the excessively attention to controlling flood and draining flooded fields, many nature irrigation canals and ditches or it is hardened or is split curved cut-off, it is less
Ground considers ecological purification function.Even if some consider, it is also difficult to consider the categorised collections such as floating material and hypostasis respectively, while right
The precipitating collection of body refuse is also insufficient, also to appropriate water storage so as in the deficiency using consideration.
Summary of the invention
The present invention provides a kind of irrigation canals and ditches in sponge city.The invention mainly comprises sawtooth pattern sink mud groove, half deep mud platform, block
Slag net, buffering gate and Man Shuipo, used technical solution are: the heavy mud groove of the sawtooth pattern has multiple and scattering device
Irrigation canals and ditches bottom of trench and keep recess depths away from water (flow) direction；Half deep mud platform is had multiple and is handed over semiellipse column gap shape
Mistake is arranged on the right and left upper half wall of irrigation canals and ditches；Buffering gate is stood using rotatable turbine in irrigation canals and ditches water outlet
End, laterally neat irrigation canals and ditches width setting and height only account for the half of trench depth；3-4 leaf is evenly distributed in the shaft of turbine
Piece, neat half ditch depth of water flow can push blade drainage；The slope Man Shui is located at the top of the nearly water outlet end unilateral side wall of irrigation canals and ditches and its neighbouring
Soil, absolute altitude is lower than neighbouring earth's surface, and along water (flow) direction absolute altitude lifting step by step, slag net is stood on before the slope Man Shui in irrigation canals and ditches.
Sawtooth pattern of the present invention sink mud groove scattering device irrigation canals and ditches bottom of trench and keep recess depths away from water flow
Direction is not only convenient for tool scraper cleaning of the soil after ramped shaped recess repeatedly precipitates and stops convenient for water flow.With half
Cylindroid gap shape is staggered the half deep mud platform on the right and left upper half wall of irrigation canals and ditches, can be in irrigation canals and ditches impeded drainage
When accommodate water flow because of widened volume and be gradually deposited on platform by flow velocity is reduced by body refuse, while some branches etc. float
Object can also be retained inlay card step by step.The rotatable turbine buffering gate for accounting for half of ditch depth of irrigation canals and ditches water outlet end neat bottom setting because
Stop the discharge that can delay water flow for the discontinuity of moving blade, creates hammed water condition raising of water level and reduce irrigation canals and ditches lower part
Water velocity reinforces the heavy mud effect of the heavy mud groove of sawtooth pattern.Meanwhile it being not enough to push turbine blade before neat half ditch depth of water flow
Draining plays and the accumulation moisture of dam is drawn to recycle function；Turbine is not by before water jet propulsion, mainly between blade and irrigation canals and ditches
The penetration mode in gap slowly discharges；Water flow is also slow release after subsiding.The slope Man Shui of nearly water outlet end setting, because of absolute altitude
Lower than neighbouring earth's surface, it is equal to the active cross-section for expanding irrigation canals and ditches top, convenient for compensating because turbine stops the emergency of loss
Drain function；Along the absolute altitude of water (flow) direction lifting step by step, and the slope Man Shui is assigned in the heavy body refuse function of water recession period.In irrigation canals and ditches
Slag net, mainly protection turbine and convenient for centralized collection and cleaning floating material.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is plan view of the invention.
Fig. 2 and Fig. 3 is partial structural diagram of the invention.
Specific embodiment
Shown in Fig. 1,2,3: a kind of irrigation canals and ditches in sponge city mainly include sawtooth pattern heavy mud groove, half deep mud platform, debris retaining
Net, buffering gate and Man Shuipo；The heavy mud groove of the sawtooth pattern has multiple and scattering device in the bottom of trench of irrigation canals and ditches and keeps recessed
It falls into depths and deviates from water (flow) direction；Half deep mud platform is had multiple and is staggered with semiellipse column gap shape in the right and left of irrigation canals and ditches
On the wall of the upper half；Buffering gate is stood using rotatable turbine in irrigation canals and ditches water outlet end, laterally neat irrigation canals and ditches width setting and
Height only accounts for the half of trench depth；3-5 blade is evenly distributed in the shaft of turbine, neat half ditch depth of water flow can push
Blade drainage；The slope Man Shui is located at the top of the nearly water outlet end unilateral side wall of irrigation canals and ditches and its neighbouring soil, and absolute altitude is lower than neighbouring earth's surface, and
Along water (flow) direction absolute altitude lifting step by step, slag net is stood on before the slope Man Shui in irrigation canals and ditches.
