Abstract
The invention discloses a water permeable masonry tailing dam structure which comprises a dam body formed by grout masonry, wherein the dam top of the dam body is of a convex drain tooth groove structure arranged in the horizontal direction in arraying mode. A dam body upper portion auxiliary drain hole, a dam body middle portion main drain hole and a dam body lower portion auxiliary drain hole which are of square structures are arranged on the upper portion, the middle portion and the lower portion of the dam body in the horizontal direction in arraying mode. The hole opening size of the dam body upper portion auxiliary drain hole and the dam body lower portion auxiliary drain hole is smaller than that of the dam body middle portion main drain hole. The groove width of the convex drain tooth groove is smaller than the groove height. The water permeable masonry tailing dam structure has the advantages of achieving the purposes of reasonably and effectively intercepting bed loads and draining water flow through drain channels arranged on different portions of the dam body and having different hole opening sizes and shapes, is simple in structure and small in work amount and saves investment cost.
Description
Technical field
The present invention relates to the dregs-blocking dam in Hydraulic and Hydro-Power Engineering, especially relate to dankness type stone-laying dregs-blocking dam structure.
Background technology
In Hydraulic and Hydro-Power Engineering, the upstream in river, particularly the upstream of mountain stream often with current drift about a large amount of to push away, suspended load, if these push away, suspended load especially bed load do not add obstruction, rush at downstream with current arbitrarily, huge harm can be caused to the Hydraulic and Hydro-Power Engineering of lower reaches of river.For reaching the impact controlling bed load, reduce downstream hydraulic engineering, often needing to build dregs-blocking dam in the upstream in river course, hydraulic engineering place, bed load is tackled.Dregs-blocking dam not only will play that interception pushes away, the object of suspended load, also wants to make smooth in water flow pass through, the stability of such guarantee dregs-blocking dam itself.The domestic dregs-blocking dam built mostly is stone-filled structure at present, utilizes rockfill self to carry out pushing off the slag, utilizes the space between enrockment to carry out water.But due to complexity and the diversity of waterpower, landform, geology and service condition, stone-filled structure might not be applicable to all engineerings as dregs-blocking dam, therefore, the suitable debris retaining form of the employing of suiting measures to local conditions to guarantee engineering safety, facilitate engineering application and manage most important.
Summary of the invention
The object of the invention is to provide a kind of dankness type stone-laying dregs-blocking dam structure, thus more effectively, more reasonably tackles river bed load.
For achieving the above object, the present invention can take following technical scheme:
Dankness type stone-laying dregs-blocking dam structure of the present invention, comprises the dam body built up by stone masonry, and the dam crest of described dam body is arrange " recessed " shape draining tooth slot structure offered in the horizontal direction; In the upper, middle and lower portion of dam body, arrangement offers main osculum, dam body lower secondary osculum in the middle part of the dam body upper secondary osculum of square structure, dam body in the horizontal direction respectively; The port size of described dam body upper secondary osculum, dam body lower secondary osculum is less than the port size of main osculum in the middle part of described dam body; It is high that the groove width of described " recessed " shape draining teeth groove is less than groove.
Main osculum in the middle part of described " recessed " shape draining teeth groove, dam body upper secondary osculum, dam body, dam body lower secondary osculum are to be tilted to down to downstream from upstream and offer.
In the middle part of described dam body, main osculum is of a size of 0.5m × 0.5 m, and the size of dam body upper secondary osculum and dam body lower secondary osculum is all 0.3m × 0.3m; The groove width 1.0m of described " recessed " shape draining teeth groove, groove height 2.0m.
Advantage major embodiment of the present invention is:
1, be opened in " recessed " shape draining teeth groove at dam body top, utilize teeth groove abutment wall to tackle bed load particle, in teeth groove, be convenient to again the smooth and easy overcurrent of upland water; It is high that the groove width of teeth groove is less than groove, not only effectively increases interception result, and also increase flow section, be convenient to great flood and pass through dregs-blocking dam smoothly.
2, main osculum in the middle part of the dam body be opened on dam body is arranged in the horizontal direction, make to be blocked by dregs-blocking dam at bed load particle, at its upstream in banking process, owing to corresponding to the bed load particle mostly being greater particle size that dam body central region is piled up in the upstream of dregs-blocking dam, if draining port size is less, then easily by the bed load particulate blockage of Large stone, be unfavorable for that current are drained, so the port size being opened in main osculum in the middle part of the dam body in the middle part of dam body is comparatively large, not only effectively bed load can be tackled but also smooth in water flow can be made to be drained by aperture.
3, bed load particle is blocked by dregs-blocking dam, at its upstream in banking process, owing to corresponding to the bed load particle mostly be compared with small particle diameter piled up in region, dam body upper and lower part in the upstream of dregs-blocking dam, if arrange larger-size draining aperture, the bed load particle of small particle diameter easily enters downstream river course by osculum, dregs-blocking dam does not have the effect of debris retaining, therefore, the port size of dam body upper secondary osculum, dam body lower secondary osculum is arranged to be less than main osculum in the middle part of dam body, like this, not only effectively bed load can be tackled but also smooth in water flow can be made to be drained by aperture.
The present invention utilizes and is opened in different parts on dam body, different openings size, difform drainage channel, thus reaches the object that reasonable, effective interception bed load plays again excretion current.Meanwhile, structure of the present invention is simple, quantities is few, saves investment cost.

Detailed description of the invention
As shown in Figure 1, 2, dankness type stone-laying dregs-blocking dam structure of the present invention, comprises the dam body 2 built up by stone masonry 1, and the dam crest of described dam body 2 is arrange " recessed " shape draining teeth groove 3 structure offered in the horizontal direction; In the upper, middle and lower portion of dam body 2, arrangement offers main osculum 5, dam body lower secondary osculum 6 in the middle part of the dam body upper secondary osculum 4 of square structure, dam body in the horizontal direction respectively; Wherein in the middle part of dam body, main osculum 5 is of a size of 0.5m × 0.5 m, and the size of dam body upper secondary osculum 4 and dam body lower secondary osculum 6 is all 0.3m × 0.3m; Namely the port size of dam body upper secondary osculum 4, dam body lower secondary osculum 6 is less than the port size of main osculum 5 in the middle part of described dam body; The groove width 1.0m of described " recessed " shape draining teeth groove 3, high 2.0m, it is high that groove width is less than groove.The drainage channel that in the middle part of " recessed " shape draining teeth groove 3, dam body upper secondary osculum 4, dam body, main osculum 5, dam body lower secondary osculum 6 are formed is to be tilted to down to downstream from upstream and offers.
