Abstract
The utility model discloses a blockage-prevention dam foundation seepage monitoring catch drain structure which comprises a catch drain (1) and a reinforced concrete cover plate (2), wherein the reinforced concrete cover plate with holes (2) is covered on the catch drain (1), a plastic blind ditch (3) is paved on the reinforced concrete cover plate with holes (2), needling earthwork cloth (4) is paved on the plastic blind ditch (3), and a crushed stone cushion layer (5) is paved on the needling earthwork cloth (4). The blockage-prevention dam foundation seepage monitoring catch drain structure can realize the reverse filter protection through paving the plastic blind ditch, the needling earthwork cloth and the crushed stone cushion layer on the reinforced concrete cover plate with holes, and guarantees that people can normally enter the catch drain to clean slag or deposit in the operation of a dam through selecting appropriate dimension of inner cavity of the catch drain for not blocking the catch drain, and effectively prevent blockage, guarantees the reliable operation of the catch drain and the safety of the dam.
Description
Technical field
The utility model relates to a kind of Dam Foundation Seepage monitoring catchwater structure of Dam Foundation Seepage monitoring catchwater structure, particularly a kind of silting blocking of reservoir.
Background technology
In Hydraulic and Hydro-Power Engineering, because of irrigation draught or generating etc. need, the formation reservoir of will building a dam usually.Seepage phenomenon to a certain degree always appears in the dam foundation, and the size of water amount of seepage is directly connected to the safety of dam body.Therefore, most important to the observation of the leakage of dam foundation water yield, generally establish catchwater and carry out seepage monitoring at dam foundation position.Empty size is less in the tradition catchwater, and its cover plate is a concrete structure with holes, easily silting, and be subjected to the restriction of empty size in the catchwater after the silting, the people can't enter and clear up, and catchwater is lost compile the function that the dam foundation seeps water, and can not reach the purpose of monitoring leakage of dam foundation water yield size.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of silting, reliable silting blocking Dam Foundation Seepage of effectively preventing to monitor the catchwater structure, thereby overcome the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of silting blocking Dam Foundation Seepage monitoring catchwater structure.Its formation comprises catchwater and steel concrete cover plate with holes, steel concrete cover plate with holes is to cover on catchwater, on steel concrete cover plate with holes, be covered with the plastics french drain, on the plastics french drain, be covered with the acupuncture geotextiles, on the acupuncture geotextiles, be covered with hardcore bed.
In the above-mentioned silting blocking Dam Foundation Seepage monitoring catchwater structure, the headroom section width d of catchwater is 0.8～1.0m, and height h is 1.0～1.2m.
In the aforesaid silting blocking Dam Foundation Seepage monitoring catchwater structure, the specification of acupuncture geotextiles is preferably 200g/m
2
In the aforesaid silting blocking Dam Foundation Seepage monitoring catchwater structure, the thickness of hardcore bed is preferably 10cm, and the rubble maximum size in the hardcore bed is 10cm.
The beneficial effects of the utility model: compared with prior art, the utility model can prevent effectively that by do anti-filter protection at traditional steel concrete cover plate with holes upper berth plastics french drain, acupuncture geotextiles and hardcore bed the inlet opening of cover plate from silting taking place.The utility model is selected suitable interior empty size (the wide 0.8m that is not less than of catchwater headroom section of catchwater simultaneously, height is not less than 1.0m), to guarantee the dam body run duration, the people can normally enter and clear up slag body or deposit in the catchwater, make catchwater not by silting, can prevent silting effectively like this, guarantee the catchwater reliability service, ensure the safety of dam body.The main feature of plastics french drain has: surperficial percent opening and void content be up to more than 85%, and collection, drainage performance are fabulous; Compressive strength can reach every square metre of tens of ton, and resistance to pressure is good; Flexible good, it is strong to adapt to the soil deformation ability; Acid-alkali-corrosive-resisting, uvioresistant, anti-aging and good endurance; In light weight, easy construction; Shape is various, adapt to the construction requirement under the complicated bad border.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plane sketch of the utility model cover plate.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment 1.As shown in Figure 1, comprise catchwater 1 and steel concrete cover plate 2 with holes, steel concrete cover plate 2 with holes covers on catchwater 1, is provided with inlet opening 6 and suspension ring 7 (as shown in Figure 2) on steel concrete cover plate 2 with holes.On steel concrete cover plate 2 with holes, be covered with plastics french drain 3, on plastics french drain 3, be covered with acupuncture geotextiles 4, on acupuncture geotextiles 4, be covered with hardcore bed 5.Wherein the headroom section width d of catchwater 1 is 0.8m, and height h is 1.0m, and the specification of acupuncture geotextiles 4 is 200g/m
2, the thickness of hardcore bed 5 is 10cm, the rubble maximum size in the hardcore bed 5 is 10cm.
During making: the first step, adopt concreting catchwater 1 as shown in Figure 1.Second step, adopt concrete prefabricated steel concrete cover plate 2 with holes as shown in Figure 2, reserve φ 100mm inlet opening 6, and suspension ring 7 are set.In the 3rd step, at steel concrete cover plate 2 upper berth plastics french drains 3 with holes, its specification is 20cm * 5cm (wide * thick).The 4th step repaved acupuncture geotextiles 4 on plastics french drain 3, its specification is 200g/m
2The 5th step, on acupuncture geotextiles 4, spread hardcore bed 5 at last, the thickness of hardcore bed 5 is that 10cm is thick, rubble maximum size is 10cm.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
