Abstract
The utility model discloses wavy tailing dam slope drainage ditches for coping with a rainstorm. The wavy tailing dam slope drainage ditches for coping with the rainstorm are characterized in that dam face troughs (3) and dam face crests (4) are formed in an original dam face (2) of a dam body (1) at certain width intervals in a digging and filling mode, bituminous concrete is poured on the surfaces of the dam face troughs (3) to form the dam slope drainage ditches, and vegetation is paved on the surfaces of the dam face crests (4) to form protective slopes (6). Due to the fact that the gradient of the slope face drainage ditches is large and waterproof materials such as the bituminous concrete is poured, a large amount of rainwater can be carried away, a seepage line is prevented from increasing sharply, and stability of the dam body is guaranteed.
Description
Technical field
The utility model relates to a kind of tailing dam dam slope dewatering installation, specifically relate to a kind of adopt pitch mix the earth small pieces of cloth used for patches in order to tackle the tailing dam dam slope gutter of heavy rain.
Background technology
The mine tailing storehouse mainly is made up of tailing dam, the facility that drains off floodwaters, dam facing drainage and other supporting facility, wherein the dam facing drainage be only second to tailing dam, the system of drainning off floodwaters influence one of key factor of dam stability.The purpose of dam facing drainage setting is to wash away dam abutment or rainwater and be trapped in dam facing and cause dam facing to draw ditch in order to prevent that the hillside heavy rain from confluxing, and for reaching this purpose, the dam slope gutter is set normally.
There are two classes in the dam slope gutter at present: a class is along hillside and dam slope joint portion the cemented rock catchwater to be set, and washes away dam abutment to prevent that the hillside heavy rain from confluxing; Another kind of is in the domatic setting in dam body downstream gutter in length and breadth, and the rainwater water conservancy diversion of dam facing is discharged outside the dam, causes dam facing to draw ditch in order to avoid rainwater is trapped in dam facing, influences the safety of dam body.
Traditional dam slope gutter generally is to pile up placed rockfill and cemented rock at the bottom of concrete, be subjected to the construction technology condition restriction, after building by laying bricks or stones, also will wipe one's face with the M5 cement paste at the ditch inner surface usually, to prevent that current are along the furrow bank seepage in the ditch, working procedure complexity in a word, consume material; In addition, the dam body of tailing dam is constantly to raise, its side slope belongs to unstable geology district, and branch traverse furrow, longitudinal furrow and crisscross ditch are just moved towards according to the plane of arranging in existing dam facing gutter, less change at the domatic soil body stress gutter is set, to such an extent as to the crack appears in gutter easily.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, and a kind of dam slope gutter simple and easy and that can effectively prevent heavy rain erosion damage dam stability of constructing is provided.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
A kind of waveform tailing dam dam slope gutter of tackling heavy rain, it is characterized in that: on the former dam facing of dam body, form dam facing trough and dam facing crest every certain width shoveling embankment, build bituminous concrete on dam facing trough surface and form the dam slope gutter, lay slope vegetation protection on dam facing crest surface.
Compared with prior art, the beneficial effects of the utility model are:
Be the waveform dam facing with original plane dam facing in-situ reformation, it is simple and easy to construct, and has saved earth and stone material.Dam slope gutter trend has been strengthened drainage effect along domatic gradient than general orientation, has guaranteed the stability of dam body.And bituminous concrete is built in the gutter, namely waterproofly can adapt to the unlikely destruction of changeable stress again.The slope vegetation protection stability of not only having strengthened side slope has played the effect of environmental protection again in addition.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model just along domatic gradient than general orientation excavation forms dam facing trough 3 every certain width dam body 1 on former dam facing 2, shoveling is filled in dam facing trough 3 both sides form dam facing crest 4.Build bituminous concrete on dam facing trough 3 surfaces and form the dam slope gutter, lay slope vegetation protection 6 on dam facing crest 4 surfaces.This had both reduced bank protection face permeability and had prevented heavy rain destruction, had effectively stoped the soil erosion of bank protection face again.
Place, the dam slope gutter gradient is bigger, and bituminous concrete is built in the gutter, i.e. the waterproof unlikely destruction of variation that can adapt to stress again, so a large amount of rainwater can be taken away in the dam facing gutter, reduce the degree of raising of tailing dam saturation line under the heavy rain situation effectively, guaranteed the stability of dam body.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
Claims (1)
1. waveform tailing dam dam slope gutter of tackling heavy rain, it is characterized in that: go up every certain width shoveling embankment at the former dam facing (2) of dam body (1) and form dam facing trough (3) and dam facing crest (4), build bituminous concrete on dam facing trough (3) surface and form the dam slope gutter, lay slope vegetation protection (6) on dam facing crest (4) surface.
