Abstract
The utility model relates to a flood discharge safety dam, which belongs to the technical field of hydraulic engineering and is mainly composed of a dam (1) and a flood discharge pipe (2). The utility model is characterized in that the upper segment of the flood discharge pipe (2) is inbuilt horizontally in the dam (1), the center height mark of the flood discharge pipe is as high as a warning water level (4), and the lower segment of the flood discharge pipe (2) is laid along the outer side (5) of the dam to the ground surface (3). The flood discharge safety dam can eliminate flood, can avoid breaches, and can ensure the safety of surrounding cities and villages.
Description
The utility model relates to the dykes and dams in a kind of river, river and lake, it belongs to the hydraulic engineering technical field.It mainly is made up of dykes and dams (1) and flood discharge pipe (2).By retrieval, also there is not the data of Flood discharge safety dyke-dam aspect at present, the most close technology is the flood spillway (Chinese patent, application number are 90110139.7) that weir, dam structure is used.
The purpose of this utility model exactly solve the flooding in river, river and lake with the method for dredging, when making flood reach certain water level, can be released by flood discharge pipe (2) safely.This Flood discharge safety dyke-dam, it is made up of dykes and dams (1), it is characterized in that also being made up of flood discharge pipe (2).The epimere horizontal laying of flood discharge pipe (2) is in dykes and dams (1), and the tube hub absolute altitude is concordant with warning line (4), and its hypomere lays to ground (3) along the outside (5) of dykes and dams (1).The caliber of flood discharge pipe (2) and tube pitch S will determine according to the size of flood discharge.
The utility model can Jiang Jiang, the flood in river and the lake releases safely and do not destroy dykes and dams, flood discharge pipe (2) is equally distributed vertically going up of dykes and dams (1), the flood that releases disperses, does not concentrate very much, so, can not cause big destruction to city on every side and rural area yet.
Description of drawings: figure-1 is a transverse cross-sectional view of the present utility model, and figure-2 is vertical view of the present utility model.
The drawing of accompanying drawing is described as follows: 1-dykes and dams 2-flood discharge pipe 3-ground 4-warning line 5-dykes and dams outside S-flood discharge tube pitch
Narrate an embodiment of the present utility model below in conjunction with accompanying drawing.
The epimere of flood discharge pipe of the present utility model (2) is a level, is embedded in the dykes and dams (1), and its tube hub absolute altitude is concordant with warning line, and the hypomere of flood discharge pipe (2) lays to ground (3) along the outside (5) of dykes and dams (1).The operating pressure of flood discharge pipe (2) should be not less than 0.1MPa, and its material can be with cement and metal etc.If flood discharge is 2000m
3/ s, warning line (4) is 8m with the vertical distance on ground (3), the flood discharge pipe
(2) diameter is 300mm, and then tube pitch S can be 30m.
Claims (2)
1. Flood discharge safety dyke-dam, it is made up of dykes and dams (1), it is characterized in that also being made up of flood discharge pipe (2).
2. Flood discharge safety dyke-dam according to claim 1, the epimere that it is characterized in that described flood discharge pipe (2) be horizontal laying in dykes and dams (1), hypomere is to lay to ground (4) along the outside of dykes and dams (1) (3).
