Abstract
The utility model discloses inner dams in a karst reservoir, belonging to the field of construction engineering of tailing reservoirs (sludge reservoirs and red mud reservoirs) in karst regions, and aiming to solve the problem that the existing insidious karst possibly causes sludge leakage. Each inner dam in the karst reservoir comprises an inner dam body arranged in the karst reservoir, wherein the porosity of the inner dam body built by stones is not more than 22% and the dry density is not less than 2.1t/m<3>; the slope ratio of the two sides of the inner dam is 1:(1.4-1.6); anti-seepage layers are arranged on the two sides of the inner dam; and anti-seepage gullets are formed on the two sides of the bottom of the inner dam body and are filled with geomembranes and concrete. The inner dams have the following beneficial effects: the whole reservoir region is divided into a plurality of reservoir sections; the reservoir sections are mutually standby to reduce leakage, thus avoiding large-area pollution incidents and shutdown of ore-washing plants because the sludge reservoirs possibly leak at the initial production stage; and the inner dams can serve as the emergency measure of the whole engineering.
Description
Technical field
The present invention relates to karst area and build construction project field, mine tailing storehouse (spoil disposal storehouse, red mud storehouse), being specially provides a kind of karst storehouse Nei Ba, so that subsequent use storehouse section to be set in the storehouse.
Background technology
The aluminous mine engineering is washed back sludge (red mud of alumina producer) and is generally entered near spoil disposal storehouse (red mud storehouse) storage; Aluminous mine for karst area (like Guangxi); Periphery spoil disposal storehouse is all built at karst and is grown the area, and the antiseep problem in spoil disposal storehouse is that construction is an a great problem in the karst region.
Cause the factor of spoil disposal storehouse seepage to have multiple; Main cause is not find out solution cavity during the prospecting, exist to omit the solution cavity without the engineering measure processing in the storehouse in, cause underground water wash away up and down with the storehouse in ooze under water and take away thin layer Quaternary system overburden soil; Thereby cause former undiscovered solution cavity to subside, sludge leaks.
At present latent karst prospecting is still a world-famous puzzle.In the prospecting, adopt the way of existing probing, physical prospecting, the fraction of searching solution cavity is difficult to reach 100%, in case the transmission accident, consequence is hardly imaginable.
Summary of the invention
In order to overcome the deficiency that existing latent karst causes causing the sludge leakage, the present invention aims to provide a kind of karst storehouse Nei Ba, utilizes the reservoir area landform; Dam in the reservoir area punctured position is built; Whole reservoir area is divided into a plurality of storehouses section, subsequent use each other, reduce leakage; Can avoid the spoil disposal storehouse to produce the initial stage seepage effectively and cause pollution in wide area accident and the stopping production of washup factory, thereby as the emergency measure of whole engineering.
To achieve these goals, the technical scheme that the present invention adopted is:
A kind of karst storehouse Nei Ba is characterized in, comprises being located in the karst storehouse karst storehouse is divided into dam at least one of a plurality of storehouses section porosity≤22% of the interior dam dam body that is built into by building stones, dry density>=2.1t/m
3, the slope ratio of said Nei Ba both sides is 1: (1.4 ~ 1.6), said Nei Ba both sides are provided with impervious barrier, and the dam body two bottom sides on said interior dam offers the antiseepage teeth groove, is filled with geomembrane in this antiseepage teeth groove, and is filled by concrete.
Further, in order to improve the anti-seepage effect of impervious barrier, said impervious barrier comprises layer of gravel, geomembrane, layer of gravel and the dry stone wall layer that is located at the outside, interior dam successively; Wherein, said two-layer layer of gravel thickness is 0.2m, and the geomembrane of impervious barrier is 800g/m
2, dry stone wall thickness is 0.3m.
For the fastness of dam dam body in guaranteeing, the maximum particle diameter of building building stones by laying bricks or stones of said interior dam dam body is less than 60cm, and mud content is less than 2%.
Said concrete is the plain concrete of C15.The wide 2000mm of the dam crest of said dam body can make things convenient for driving above that.
By said structure, according to spoil disposal storehouse actual landform,, build one or many interior dams at the physical features punctured position, whole reservoir area is divided into a plurality of independent storage mud place, the initial stage independently uses, and the later stage is linked to be integral body.Dam material is gathered materials on the spot, and adopts piece stone to build a dam, and height of dam is provided with as required, and safety of dam body is by the full mud of a side, and the temporary construction in the empty storehouse of opposite side designs.Dam slope is provided with impervious barrier, avoids the sludge infiltration of dam body both sides to be communicated with.
Compared with prior art; The invention has the beneficial effects as follows: the present invention utilizes the reservoir area landform, and dam in the reservoir area punctured position is built is divided into a plurality of storehouses section with whole reservoir area; Subsequent use each other; Reduce leakage, avoided spoil disposal storehouse production initial stage possibility seepage and caused the pollution in wide area accident and the stopping production of washup factory, can be used as the emergency measure of whole engineering.
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.
Description of drawings
Fig. 1 is the vertical section constructional drawing of an embodiment of the present invention;
Fig. 2 is the vertical view of Fig. 1.
In the drawings:
1-storehouse section one; 2-storehouse section two; Dam 4-goes up the dam step in the 3-;
The 5-impervious barrier; 6-original place upper thread; 7-antiseepage teeth groove; The clear baseline of 8-.
The specific embodiment
At first, in the scope of reservoir area, choose suitable location, as punctured position is as interior dam dam site in the reservoir area, ice cleaning dam foundation humus soil, weeds, turquoise etc. are to fresh old soil layer.
In the 50m scope of dam body two ends, get stone nearby, last dam building stones require fresh complete, and grating is continuous, and maximum particle diameter is less than 60cm, and mud content is less than 2%.
Adopt heavy-duty machinery vibration layered rolling, every layer of shop stone thickness, the test of number of rolling on-site rolling are confirmed.Require the slope ratio of Nei Ba both sides to be 1:1.5, the dam body after rolling requires porosity≤22%, dry density>=2.1t/m
