Description

Multi-stage porous pipe weir shunts and warps system

Technical field

The utility model relates to the fully-loaded streams in hydraulic and hydroelectric engineering to external drainage warping works, more particularly, to more Grade hole pipe weir, which shunts, warps system.

Background technique

The riverbed of fully-loaded stream often has silting phenomenon, for guarantee river operational safety, it is necessary to warped with Reinforce embankment.Now by taking China the Yellow River as an example, the Yellow River downstream channel is aboveground river world-famous, and river bed is higher by two sides ground 3m ~9m, while river width maximum reaches 25km between the dyke of downstream or so, main stem is gone around swing, " Yokogawa ", " oblique river " and " Shun Dihang Flood " phenomenon has generation more, brings very big hidden danger to the Yellow River flood control.

To solve riverbed silting phenomenon, mainly takes warp the measure of reinforcing embankment in embankment land side at present, i.e., The grid embankment continuously sealed is built along dike in embankment land side, the high extraction of water containing Shahe is entered by mud carrier and is gone here and there one by one Clear water in dike pond is bled off, is increased by stages step by step after sediment deposition by sub- embankment pond even.Above-mentioned silt arrester effect is good, again Silt in river is utilized, becomes the major measure of downstream embankment reinforcement.But occur for fully-loaded stream part section The phenomenon that " slot is high, beach is low, dike root is hollow ", i.e., " double suspended channel " as shown in Figure 7, during the unfavorable form of " double suspended channel " is easily led to Chang Hongshui overbank, when flood passage, form oblique river, Yokogawa, along the river regime of the unfavorable embankment safety such as dike flood passage.To alleviate because " second level is outstanding Threat caused by the unfavorable form in river " to Seawall safety is arranged in dyke side of bordering on the river using building guard dam and choose the conduct of bank of wandering about as a refugee It applies, but the low-lying topography of dike root does not change.

Utility model works principle is summarized as follows:

The utility model changes water flow point using the sediment carrying capacity of water flow and the high power correlation of flow rate of water flow Cloth condition will affect its carrying amount.Different characteristics is flowed by weir flow and hole, realize sediment transport and falls the unification of silt.

The top overflow area 10 of low comb composition, top overflow are equivalent to sharp-crested weir overflow, and inflow-rate of water turbine is big, and sediment carrying capacity is strong. Permeable hole pipe weir bottom hole stream, the overcurrent under upstream and downstream water-head and flow velocity effect, overcurrent flow velocity is small, and sediment carrying capacity is weak, makes mud Husky tunneling boring precipitating.

The utility model proposes and the new method that water flow subregion forms different fluidised forms by hole pipe weir is utilized, i.e., using sandy The method that river water and river shoal topography fall silt naturally.

The utility model proposes new hole pipe weir technologies: in siltation area's overcurrent depression, being overflow by hole arranged pipe weir crest Area 10 is flowed to ensure certain flow and flow rate, is passed through its different location and is distributed the uniformity for guaranteeing carrying, through hole stream reduces Flow section underflow flow velocity makes silt fall silt, realizes and carrys out husky duration and fall husky uniformity.That is: it is located on permeable standpipe 7 The water hole 8 of 1/4 height of portion open up density > be located at permeable 7 lower part of standpipe, 3/4 height water hole 8 open up density.

Engineering is reversible: the standpipe on every round pipe weir can be transferred to reaching to fall after silt requires, and not change the natural soil property rock in riverbed Sexual element；Replace the materials such as building stones, concrete, pollution-free industrial plastic product material (PE pipe) realization is fully utilized and falls silt, it is raw State.
