Abstract
The utility model discloses a light gangue dam face drainage ditch, which is structured by three-sided light precast reinforced concrete; each section of drainage ditch is connected with each other to compose an interweaving drainage network. A first frontal end head of the drainage ditch is connected with the gangue dam. The utility model has the advantages that the section of the light drainage ditch is light and thin; the light drainage ditch consumes less materials and has less production cost, wherein, each section of ditch only needs a 0.753 multiplying 10<-3>m<3> of C20 reinforced concrete, 30% lower compared with the production cost of the traditional M5 cement mortar bricklaying drainage ditch. As only precast components need to be installed on the field to fill the joints, the utility model has shorter process flow and faster speed compared with the construction process flow of the traditional dam face drainage ditch (selecting the rubble-allocating the mortar-bricklaying the rubble-plastering). Besides, the utility model overcomes the disadvantage that the water flow in the traditional dam face drainage ditch is easy to leak. The light drainage ditch is convenient to manage and maintain.
Description
Technical field
The utility model relates to a kind of light-duty tailing dam dam facing gutter, especially a kind of light-duty tailing dam dam facing gutter.
Background technology
The mine tailing storehouse is the association of the various structure of the mine tailing that produces behind the safe storage mine ore dressing, most ofly constitutes by tailing dam, the facility that drains off floodwaters, dam facing drainage, water seepage drainage facility and supporting facility (as observation facility, facility on duty etc.) are several.According to statistics, in the various great disaster in the world, mine tailing storehouse disaster is only second to generation earthquake, cholera, flood and hydrogen bomb etc. and occupy the 18th.In a single day it have an accident, and will cause significant damage to area, the downstream people's life and property, and environment is caused severe contamination.Wherein, the dam facing drainage be only second to tailing dam, one of the key factor that influences mine tailing storehouse security and stability of the system of drainning off floodwaters.
Dam facing drainage function is: prevent that rainwater that hillside and dam facing compile to the washing away of tailing dam dam abutment, dam facing, avoiding causing the bogginess of tailing dam dam facing, reduce the soil erosion of tailing dam dam facing, help the stability of tailing dam.The dam facing drainage mainly is made up of dam facing gutter, dam abutment gutter.
The dam facing gutter is arranged on the dam facing of tailing dam downstream, and the dam abutment catchwater is then along being provided with on the hillside of slope, tailing dam downstream and junction, hillside, two sides.Two kinds of branch traverse furrow and longitudinal furrows are moved towards according to the plane of arranging in the dam facing gutter, and traverse furrow is along tailing dam packway disposed inboard, and spacing is generally 10m on the elevation, longitudinal gradient 1%; Longitudinal furrow is arranged perpendicular to the tailing dam axis of dam, longitudinal furrow spacing 50～100m.Traverse furrow and longitudinal furrow are interconnected, and form the dam facing drainage network, and effectively that the tailing dam downstream is domatic rainwater is collected side by side toward the downstream.Longitudinal and transverse ditch cross section is identical, generally is rectangle.Traditional gutter mostly is masonry of cement mortar piece stone (also using the masonry of cement mortar common brick once in a while) and forms, be subjected to the construction technology condition restriction, ditch sidewall and base plate thickness minimum after generally building by laying bricks or stones also have 300～350mm, cross dimensions is thicker big, for preventing that current are along the furrow bank seepage in the ditch, also need at ditch inner surface M5 cement sand plaster 2 centimetres of the minimum thickness of wiping one's face.Not only expend building stones, speed of application is slow, and the slit is big, cement sand plaster very easily produces the crack because of cemented rock is constructed, easily cause current seepage in the ditch, directly infiltrate in the mine tailing dam body, cause the bogginess of tailing dam dam facing, form soil erosion, influence the security and stability of tailing dam.
Summary of the invention
The purpose of this utility model is to provide a kind of light-duty tailing dam dam facing gutter, and this gutter is with installing prefabricated units, and antiseepage is good, tailing dam is safe.
The technical solution of the utility model is: a kind of light-duty tailing dam dam facing gutter, this light-duty tailing dam dam facing gutter is made of three lightweight plate (for example prefabricated reinforced concrete), every joint gutter is connected, constitutes in length and breadth the drainage network that links to each other, and the termination of the most last joint in gutter is connected with tailing dam.
Advantage of the present utility model is: this light-duty discharge section is frivolous, and consumptive material is few, and cost is low, and every joint ditch only needs C20 steel concrete 0.753 * 10
-3m
3, than the cost low 30% of traditional M5 masonry of cement mortar rubble drain.On-the-spot only need to install prefabricated units → joint filling, flow process is short, speed is fast than the construction technology in traditional dam facing gutter (select piece stone → configuration mortar → masonry block stone → wipe one's face).Overcome the shortcoming of current easy to leak in the ditch of traditional dam facing gutter.Management maintenance is convenient in this light-duty gutter.

Fig. 2 is the light-duty tailing dam dam facing of a utility model gutter A-A sectional view.
The specific embodiment
A kind of light-duty tailing dam dam facing gutter, this light-duty tailing dam dam facing gutter is made of three prefabricated reinforced concrete, and every joint gutter is connected, constitutes in length and breadth the drainage network that links to each other, and the termination of the most last joint in gutter is connected with tailing dam 2.
The present invention does not change the dam facing gutter in the domatic layout in tailing dam 2 downstreams, just to carrying out innovation on the structure of dam facing gutter, form a kind of new light-duty tailing dam dam facing gutter: adopt the light prefabricated reinforced concrete structure of C20, rectangular cross section, net section 0.3m * 0.3m; Side wall top width 6cm, the thick 8cm of base plate, bottom width 45cm; Prefabricated gutter 1m one joint.During on-the-spot the installation, rank mutually successively, it is tight that every joint seam crossing only needs the M5 cement mortar will stitch filling, after the M5 cement mortar for the treatment of filleting is hardened, just realized the splicing between every joint prefabricated units.
Claims (1)
1, a kind of light-duty tailing dam dam facing gutter, it is characterized in that: this light-duty tailing dam dam facing gutter is made of three lightweight plate (1), every joint gutter is connected, constitutes in length and breadth the drainage network that links to each other, and the termination of the most last joint in gutter is connected with tailing dam (2).
