Specific implementation mode
The following further describes the present invention with reference to the drawings.
As shown in Figure 1 and Figure 2, the present invention includes the gear dam main body being arranged in cheuch, and gear dam main body is divided into excessive
Section 1 and non-overflow section 2 are flowed, the overflow segment 1 is that multiple buttresses 11 are spaced the comb teeth-shaped structure being arranged to, and are arranged on gear dam
In the middle part of main body, the non-overflow section 2 is monolithic devices, and setting is in 1 both sides of overflow segment, and whole height is higher than overflow segment 1.Specific
When arranging overflow segment 1 and non-overflow section 2, each section of length, thickness and height equidimension should be considered according to actual place, to ensure
The direction of dredging of stable structure and overflow segment 1 is moved towards with cheuch subject to unanimously.
Using the comb teeth-shaped structure that 11 interval of multiple buttresses is arranged to as overflow segment 1, ensure that flood discharge, it is lower sluice stream
Meanwhile, it is capable to which the mountain stone and branch to bulk play the role of blocking, avoid that downstream waters is caused to stop or be destroyed.And work as mudstone
When stream outburst, since the overflow segment 1 at middle part is less than the non-overflow section 2 of both sides, so mud-rock flow can return to the overflow segment 1 at middle part
Hold together, so that mud-rock flow 1 is let out under dam body middle part, avoid that downstream cheuch two sides are caused to wash away, reduces material resource and increase.And mud-rock flow
Viscous flow phenomenon can be formed when by the overflow segment 1 of comb teeth-shaped, its flow velocity is made to reduce, scale reduces.Therefore the structure, which has both, blocks
Effect is kept off and dredged, existing debris dam, shilong dam, crib dam etc. are better than to the protection effect of mud-rock flow.
In order to enable overflow segment 1 to play best effect of putting together to mud-rock flow, obtained according to theory analysis and experiment, institute
The difference in height of the overflow segment 1 and non-overflow section 2 of stating gear dam main body is preferably 1~2m, wherein it is preferred that 1.5m.
Since 1 one side of overflow segment will block to mountain stone, the branch of bulk, on the one hand meet the mistake of mud-rock flow again
Stream needs, so the gap of each buttress 11 cannot be too big, it can not be too small, and while also to ensure the stabilization of 11 self structure of buttress
Property.According to the scale and characteristic of general mud-rock flow, the gap of 1 each buttress 11 of the overflow segment and thickness control 100~
150cm is more reasonable, both ensure that the intensity of buttress 11, and good viscous flow effect can be also played to mud-rock flow.
