Abstract
The present invention relates to a flood discharge dam or a flood discharge section of a dam, which is particularly to used for water discharge and flood discharge. The present invention is characterized in that the bottom of a dam body is provided with a plurality of flood discharge culverts, the two ends of every flood discharge culvert are respectively provided with gates, and the flood discharge culverts become a closed system. Pumping holes are arranged in the dam body and are led into the flood discharge culverts, so that the water in the culverts is pumped through the pumping holes to be convenient for maintenance. The present invention also relates to a gate structure and a lifting system thereof which accord with the fluid mechanics principle. The flood discharge dam can rapidly discharge flood at ordinary times and in emergency periods, and the water level of a reservoir can be reduced to a safe level in a short time. The present invention has the capabilities of desilting and discharging sand.
Description
The present invention relates to be exclusively used in the design of the dam for flood discharger of draining flood discharge effect or the flood discharge section in the dam.
Traditional dam is for solving the draining flood discharge problem in unusual time (as great flood takes place), all need construct one section dam for flood discharger (or flood discharge section of title dam), the draining flood discharge of this dam for flood discharger or flood discharge section mainly is to be finished by the floodwater releasing port that is arranged on dam crest.The major defect one that is carried out the draining flood discharge by the floodwater releasing port of dam crest is that draining flood discharge speed is slow; The 2nd, the following water of floodwater releasing port can not be discharged from floodwater releasing port, if (as great flood, earthquake etc.) need drain the water of the following water level of floodwater releasing port in the unusual time, then can only finish by other non-ad hoc channel (as ship lock, generating position etc.) of dam, make these non-ad hoc channels adapt to drainage requirement, the technical requirements that certainly will improve this class facility greatly; The 3rd, this flood discharge dam lacks capability of sediment outflow, and the silt that the reservoir area accumulates at the bottom of the dam can not be discharged by floodwater releasing port, and it is husky that often the artificial way of employing is carried out desilting row, and it is heavy to work.
The objective of the invention is for solve the existing the problems referred to above of traditional dam design a kind of at ordinary times and the unusual time all can carry out quick flood discharge draining, but reduce to the water level of reservoir on the safe level within a short period of time, and have the dam for flood discharger that is exclusively used in draining flood discharge effect of desilting capability of sediment outflow or the flood discharge section of dam.
The flood discharge section of dam for flood discharger that the present invention is constructed or dam, its characteristics are that the bottom of dam body makes up several flood discharge culverts, two ends (water inlet end and water side) at each flood discharge culvert are provided with gate respectively, lead among the flood discharge culvert being provided with suction eye on the dam body simultaneously.When the two ends gate is opened, current will (V be a water speed with V=2gh, h is the height of water level of dam, g is an acceleration of gravity) flow velocity flow through culvert fast, the water level of dam is high more, the speed of flood discharge draining is fast more, because the flood discharge culvert is opened Yu Badi, and high water flow velocity is arranged, the silt at the bottom of the dam will be taken away by current scour, thereby reach the husky purpose of desilting row.When the closing gate of two ends, dam is draining no longer, the culvert of flood discharge simultaneously forms the system of a sealing, at this moment can drain the water in the culvert by the suction eye on the dam body where necessary, so that culvert inside is keeped in repair, be exceedingly fast owing to flow through the current of culvert, current and silt wash away the meeting culvert and cause wearing and tearing, and this maintenance is necessary.In order to improve the intensity of the water-fast stream silt underwashing of culvert, must lay wearing layer at the bottom and the inwall of flood discharge culvert.
The said gate of the present invention adopts forms " doorframe " shape hurdle sluice gate by gate body, top flashboard and both sides flashboard, and its top flashboard and both sides flashboard can be done folding or telescopic moving with respect to the gate body.
During above-mentioned closing gate, at flood discharge culvert port, the dam body end face of gate body and flood discharge culvert leaves the gap to the landing of gate body, seals this gap by mobile top flashboard and both sides flashboard again from the front retaining, and the water proof of finishing flood discharge culvert port seals.Because the gate body is designed to directly not contact with dam body, leaves certain clearance, like this, when putting down gate, equal with the static pressure of back side because of meeting water of gate body, the static pressure of water will show as and not hinder the gate motion; And the dynamic pressure that the gate front is born, because gap location has water constantly to flow into, the two (front current and side current) resistance that motion is produced to gate will have part to offset, thereby in fact as long as just can reach the purpose of barrier gate by the gravity of gate.
Above-mentioned gate body and top flashboard can adopt the operation of drag-line lifting structure, and wherein the gate body is done the lifting operation by cable systems and lifting gear traction by gate riser guide post and guide wheel, and the top flashboard is also done the folding operation by the cable systems traction.Said both sides flashboard can adopt and be built in the gate main body structure, drives from the gate body outwards flexible by piston type.Both sides flashboard telescopic moving can be by electronic or hydraulic-driven.
The present invention can be designed to cavity type with the gate body, and feeding/discharging device to this cavity is set, by water storage or draining in the cavity of gate body, the weight of regulating gate, to adapt to the needs of gate lifting operation, when this cavity water storage, the water feed apparatus on the body that can open the sluices is water inlet automatically in cavity, and also available artificial mode pumps into; Draining then is to inflate or pressurization in the cavity of gate body, can reach the draining purpose.
For improving the tightness of gate and flood discharge culvert port, the sealing-in position of said gate each several part and dam body must mosaic sealing material.
Dam for flood discharger of the present invention integrates flood discharge draining and channel sand-flushing desilting function, and the design of its structure and equipment meets hydromechanical principle, and is safe and reliable to operation, is easy to control.This dam for flood discharger is easy to construction and maintenance, and is cheap, is suitable for using in various types of reservoir dams.
