Abstract
The invention relates to a drain dam with the water draining function, characterized in that the two sides and the central part of the dam body is provided with a plurality of drain culverts in the horizontal direction, the two sides and the central part is provided with a plurality of drain culverts in the vertical direction. The lowest culvert of the vertical culverts is a small size culvert, the size of the culvert is gradually enlarged from the bottom to the top, the draining speed is swifter when the water level of the dam is higher.
Description
One, technical field
The present invention relates to be exclusively used in the dam for flood discharger of draining flood discharge effect.
Two, background technology
Traditional dam all need be constructed dam in order to solve the draining flood discharge problem of unusual time, is mainly finished by the sluice of dam crest when the draining flood discharge.Shortcoming is that drainage speed is slow, and water has only when surpassing floodwater releasing port by the time, just can carry out draining.
Three, summary of the invention
In order to solve the problems referred to above that traditional dam exists, the present invention has a kind of just continuing the function of draining at ordinary times, when the generation great flood, and all flood discharge culvert drainings fast, water level is high more, and draining is fast more.
Dam for flood discharger of the present invention, because of the flood discharge culvert is arranged at the bottom of dam body, when water level during to first floor flood discharge culvert, what water will not stop flows, and can not make the water on the riverbed become stagnant water, and the water yield that stores just can be used at ordinary times.This dam for flood discharger is easy to construction and makes up, and is suitable for using in the few river course of mud, and structure is some in the river course has the dam for flood discharger of drop just to have several small reservoirs.Dam for flood discharger is when making up, and the flood discharge culvert of minimum one deck has a segment distance from the river bed, decide the height of flood discharge culvert by the water supply volume that needs at ordinary times.
Accompanying drawing is the Facad structure schematic diagram of dam for flood discharger.
1 is dam body among the figure; 2 are the flood discharge culvert; 3 is horizontal plane.
Below in conjunction with accompanying drawing the CONSTRUCTED SPECIFICATION of the embodiment of the invention being done one describes in detail;
The main feature of this dam for flood discharger is: 1, the bottom of dam body 1 makes up some flood discharge culverts 2 along same horizontal plane, the quantity of flood discharge culvert 2 and highly also have size by storage capacity with come the water yield to determine.2, the flood discharge culvert that dam body 1 is minimum vertically makes up some flood discharge culverts 2 more than 2, and the quantity of this culvert, height and the size flow during by coming the water yield and flood takes place at ordinary times decides.Dimension of opening is from bottom to top, and is ascending, promptly high more flood discharge culvert, and dimension of opening is big more, and its water yield is also just big more.3, plane storing water and just can use at ordinary times below 3.
Claims (4)
1, a kind of dam for flood discharger that is exclusively used in draining flood discharge effect is characterized in that being built with some groups of flood discharge culverts at the same horizontal plane in dam body upper edge, vertically is built with some groups of flood discharge culverts.
2, dam for flood discharger according to claim 1 is characterized in that the flood discharge culvert that vertically makes up, and the bottom is a small size flood discharge culvert, and from bottom to top, size increases gradually.
3, flood discharge culvert according to claim 1 is characterized in that said flood discharge culvert has the wearing layer of thickening.
4, flood discharge culvert according to claim 1 is characterized in that the below, hole stores the water that uses at ordinary times along the minimum big vast culvert of a drainage of horizontal plane.
