The concrete layer upper surface that permeates water still can set up the concrete supporting course as required, the layer is ground to anti the dashing of concrete for absorption basin protects smooth bottom plate and has better intensity, can adopt the prefabricated concrete column that permeates water to replace the wash port simultaneously, and feasible construction is more simple and convenient, and is efficient, can not block up, and intensity is higher, and it is favourable to wear -resistant to the bottom plate.
Description
Technical field
The utility model relates to a kind of absorption basin protection-apron base plate anti-filter discharge structure, is applicable to Hydraulic and Hydro-Power Engineering.
Background technology
In hydroelectric project, for reducing absorption basin protection-apron uplift pressure, needing to arrange draining at absorption basin protection-apron base plate, meanwhile, in order to avoid covering layer generation seepage failure in basis during draining, also needing to arrange loaded filter under absorption basin protection-apron base plate.Usual way arranges one deck loaded filter bottom absorption basin protection-apron base plate, then on absorption basin protection-apron base plate, arranges vertical drainage hole, in hole can filled plastics gutter in case drain hole blocking.Loaded filter is generally the grit material according to the preparation of design grating, and under needing during absorption basin protection-apron construction of bottom plates, dig certain depth, basis often exists infiltration, and this brings difficulty to loaded filter construction, and quality also not easily ensures.In addition, on base plate vertical drainage hole mostly be the later stage boring or bottom slab concreting before pipe laying, build front pipe laying due to underplate concrete and there is vertical built-in pipe both fixing difficulties, affect again concrete warehousing, pave, vibrate, therefore many employing later stage boring, and later stage drillman work amount is large, especially thicker (the 3m of base plate, even more than 3m) time, also likely block reinforcing bar, unfavorable to structure stress.
Utility model content
Technical problem to be solved in the utility model is: the absorption basin protection-apron base plate anti-filter discharge structure providing a kind of easy construction, does not affect by infiltration, can ensure construction quality simultaneously.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: absorption basin protection-apron base plate anti-filter discharge structure, comprise basic covering layer, basic tectal upper surface is provided with pervious concrete layer.
Further: the upper surface of pervious concrete layer is provided with concrete anti-abrasion layer, and concrete anti-abrasion layer is provided with drain hole.
Further: the upper surface of pervious concrete layer is provided with concrete anti-abrasion layer, in pervious concrete layer, be provided with prefabricated pervious concrete post, and make the outer end of prefabricated pervious concrete post through concrete anti-abrasion layer.
Further: the upper surface of pervious concrete layer is provided with concrete bearing stratum, concrete anti-abrasion layer outward successively by interior, and concrete bearing stratum, concrete anti-abrasion layer are provided with the drain hole be connected.
