Description
Technical field
The present invention is a kind of hydraulic engineering field water retaining structure, particularly a kind of autocontrol steel facing dam.
Background technology
According to statistics, there are more than 50000 bars in drainage area river in the range of 100-1000 square kilometre, the whole nation,
Wherein it is positioned at mountain area greatly.Mountain stream has the feature that water yield spatial and temporal distributions is uneven, Summer and winter flow
Very different, up to hundreds times.Gear sluicing facility in hydraulic engineering at present often uses gate, and it can be installed
On the hydraulic structures such as Overflow Section, spillway on bank, spilled water hole, hydraulic tunnel, to intercept current, control
For the purpose of controlling the water circulation position, regulation flow, discharge silt and drift etc..Traditional gate is a system engineering,
Including gate flap, bury many accessory structures such as solid part, open/close machinery, gate pier, lock chamber, access bridge.Wherein door
Leaf includes again load-carrying members, walking support, support arm, hinge, antipriming, hanger etc.；Bury solid part to include
Track, free bearing, sealing seat, corner protector etc..On the whole, gate have design complexity, have difficulty of construction and
The shortcoming such as relatively costly.And gate pier can produce bigger flood passage resistance when flood period sluices, and affects in river course
Flow condition.Therefore, less for usual flow, water level is relatively low, flood period, flow significantly increased, to row
Flood requires higher mountain stream, it is proposed that a kind of autocontrol steel facing dam.This autocontrol steel facing dam is permissible
Arbitrarily regulated dam body lifting heights by water pump, and can fall completely within riverbed when sluicing.With common sluice
Compare to have and sluice flood period fully, the advantage not affecting flood passage.Relative to have been put into use rubber slab,
It has wear-resisting feature, is more suitable for making on the river, bed load riverbed, mountain area that water flow mud-sand content is higher
With.This autocontrol steel facing dam passes through artificial water-filling, and the mode of automatic drainage is controlled, and takes into full account
The feature in bed load river, mountain area, is that one possesses the multi-functional ecological hydraulic structure of low impact, meets with water
Environment and Ecology protection and view and entertainment environment build for the purpose of the demand of river comprehensive realignment.
Summary of the invention
The purpose of the present invention aims to above-mentioned existing problems, it is provided that a kind of autocontrol steel facing dam, this autocontrol
Steel facing dam simple in construction, difficulty of construction are low, and critical piece uses the form of prefabrication, makes the construction period big
Significantly shortening, cost is relatively low, has preferable economic serviceability in engineering, is particularly well-suited to flow at ordinary times little,
Water level is low, flood period flow big, flood discharge capacity is required higher bed load river, mountain area.

Water inlet connect, outlet pipe is connected with the outlet of float chamber, and water intaking valve and outlet valve are respectively arranged at and river
The position that face maintains an equal level.
The operation principle of the present invention: when this steel facing dam utilizes the level of tail water to be less than certain altitude, make water surface ball float
Height reduction, controls watertight rubber and opens inlet valve, closes flowing water Valve, and by Artificial Control water pump,
To bottom, steel facing dam water tank water-filling, steel facing dam crest is played the novel water retaining structure of dash.Work as the level of tail water
During rising, the water within water tank can be will be filled with and discharge, discharge head pressure, make steel facing dam naturally fall,
Reach the effect sluiced.
The invention has the beneficial effects as follows:
This autocontrol steel facing dam has the feature of standardized production, reliable in quality, utilize people's chemical water pump water-filling and
Floating ball rod device automatic drainage；In the dash phase, steel facing dam can bear abrasion and the punching of bed load sediment granule
Hit impact；In flood period, pre-manufactured steel face dam is avoided that after falling after rise that works is affected by Sediment Siltation, and to river
Road flood passage is without impact, and ball float system can be automatically adjusted downstream line sluicing simultaneously.This autocontrol steel facing dam structure
Simply, difficulty of construction low, critical piece use prefabrication form, make the construction period the most significantly shorten, become
This is relatively low, has preferable economic serviceability, be particularly well-suited to flow at ordinary times little in engineering, and water level is low,
Flood period, flow was big, and flood discharge capacity is required higher bed load river, mountain area.
