Abstract
The utility model discloses a rock-fill dam for preventing seepage by combining with grouted stone. The rock-fill dam comprises a grouted stone filling region (2), a broken stone filling region (3) and a stone pilling region (4), wherein the height of the broken stone filling region (3) is 0.6-0.7 time of the total height of a dam body, and the upstream end face of the grouted stone filling region (2) is provided with a glass fiber reinforced plastics seepage-proofing layer (1). By adopting the grouted stone as a seepage-proofing structure and combining with the glass fiber reinforced plastics seepage-proofing layer, the rock-fill dam has the advantages of a simple structure, and capabilities of effectively reducing size of the dam body, decreasing project amount and saving investment. Because glass fiber reinforced plastics have excellent properties of preventing seepage, resisting acid, alkali and oil, and the like. The rock-fill dam is suitable for a water retaining dam of water conservancy and hydropower, and is also suitable for tailing dams such as chemical industry and mine, thus the application field of the rock-fill dam is greatly expanded, and remarkable economic benefit and social benefit are obtained.
Description
Technical field
The utility model relates to the loose rock dam technical field, particularly relates to a kind of loose rock dam that combine stone masonry to carry out antiseepage.
Background technology
In Hydraulic and Hydro-Power Engineering,, perhaps need build a dam and form the mine tailing storehouse at chemical industry, mine etc. because of needs such as irrigation draught or the generating formation reservoir of will building a dam usually.The dam mainly contains types such as concrete dam and loose rock dam, and dam type commonly used in the loose rock dam has core wall rockfill dam and rock (hereinafter to be referred as face dam).The antiseepage body of face dam is mainly concrete slab, geotextiles (film), pitch plank etc.; Thereafter for rolling dam bodys such as rockfill; In industries such as chemical industry, mine tailing often is corrosive to concrete, pitch plank especially, and the construction investment of geotextiles (film) is bigger; Cause the use of panel material to receive very big restriction, and the volume of existing loose rock dam also all causes more greatly, and engineering quantity is big, investment is high.
Summary of the invention
The utility model technical problem to be solved is the defective that overcomes existing loose rock dam, and a kind of loose rock dam that combine stone masonry to carry out antiseepage are provided, and the build of these loose rock dam is littler than existing loose rock dam, has reduced engineering quantity, has reduced investment.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme;
The loose rock dam that the utility model combines stone masonry to carry out antiseepage comprise stone masonry enrockment district 2, broken body enrockment district 3 and enrockment district 4; The height in broken body enrockment district 3 is 0.6～0.75 times of dam body overall height, and the upstream face in stone masonry enrockment district 2 is provided with glass fiber reinforced plastic impervious barrier 1.
Above-mentioned combination stone masonry carries out the loose rock dam of antiseepage, and the thickness of glass fiber reinforced plastic impervious barrier 1 is 3～5mm.
The slope ratio in each enrockment district is respectively: the up stream slope in stone masonry enrockment district 2 is than being 1:0.2～0.3, and the slope, downstream is than being 1:0.2～0.25; The slope, downstream in broken body enrockment district 3 is than being 1:0.45～0.6; The slope, downstream in enrockment district 4 is than being 1:1.3～2.0.
Compared with prior art, the utility model adopts stone masonry as leakage preventing structure, combines the glass fiber reinforced plastic impervious barrier simultaneously; Simple in structure, can effectively reduce the dam body build, reduce engineering quantity; Reduce investment outlay, because glass fiber reinforced plastic has excellent properties such as antiseepage, acidproof, alkaline-resisting, oil resistant, the utility model not only is applicable to the checkdam of water conservancy and hydropower; Also be applicable to the tailing dam in chemical industry, mine etc., widened the application of loose rock dam greatly, have remarkable economic efficiency and social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The utility model loose rock dam comprise stone masonry enrockment district 2, broken body enrockment district 3 and enrockment district 4; The height in broken body enrockment district 3 is 0.6～0.75 times of dam body overall height; Upstream face in stone masonry enrockment district 2 is provided with glass fiber reinforced plastic impervious barrier 1, and the thickness of glass fiber reinforced plastic impervious barrier 1 is 3～5mm.The up stream slope in stone masonry enrockment district 2 is than being 1:0.2～0.3, and the slope, downstream is than being 1:0.2～0.25; The slope, downstream in broken body enrockment district 3 is than being 1:0.45～0.6; The slope, downstream in enrockment district 4 is than being 1:1.3～2.0.
During the dam body construction:
At first accomplish building by laying bricks or stones of stone masonry enrockment district 2; Adopt M7.5 mortar building block stone, piece stone profile roughly is square, and upper and lower faces is substantially parallel and roughly smooth; No wedge angle, featheredge, piece is thick should be greater than 20cm; Maximal side (length) should not be greater than 100cm, and saturated compressive strength is more than the 30MPa, and width at dam crest B confirms according to standard and service requirement.
Two, accomplish the construction in stone masonry enrockment district 2 after, its upstream face is carried out beginning after the smooth processing construction of glass fiber reinforced plastic impervious barrier 1, glass fiber reinforced plastic impervious barrier 1 raw material adopt epoxy resin.The job practices of glass fiber reinforced plastic impervious barrier 1 is: one epoxy resin of primary coat treats that it solidifies one epoxy resin → paving glass fabric one deck of one epoxy resin → paving glass fabric one deck in back → brush again → be coated with → be coated with one epoxy resin → paving glass fabric one deck → one front cover of brush ring epoxy resins promptly to accomplish construction.
Three, accomplish filling of broken body enrockment district 3 and enrockment district 4.It is the above rubble of 30MPa that broken body enrockment district 3 adopts piece stone maximum particle diameter 40cm～60cm, saturated compressive strength; Enrockment district 4 is a placed rockfill; Piece stone profile roughly is square, and upper and lower faces is substantially parallel and roughly smooth, and no wedge angle, featheredge, piece is thick should be greater than 20cm; Maximal side should not be greater than 100cm, and saturated compressive strength is more than the 30MPa.With automobile above-mentioned stockpile is transported to the broken body enrockment of dam district 3 and enrockment district 4, adopts bulldozer to pave, bed thickness 80cm sprinkles water 15% then, adopts vibrating roller to roll 8～10 times, satisfies the requirement of porosity 15～20%.Continue construction to filling completion.
