Abstract
The utility model discloses a kind of sand-gravel dam slope protection device; comprise be laid on sand-gravel dam domatic on multiple concrete blocks; each described concrete block centre position is provided with a drain hole, is embedded with pvc pipe, is filled with stone in described pvc pipe in described drain hole.Water in dam, by arranging drain hole, pvc pipe and stone in concrete block, can be discharged, prevent inverse osmosis to the destruction of dam slope by the utility model in time.Meanwhile, the mode of polylith concrete block splicing can adapt to dam deformation preferably, prevent cracking destruction, and concrete block can carry out before construction, has batch machining prefabricated, and site operation speed is fast, is convenient to the advantages such as maintenance or replacing.
Description
Technical field
The utility model relates to sand-gravel dam technical field, particularly relates to a kind of sand-gravel dam slope protection device.
Background technology
Sand gravel is extensively distributed in riverbed and bank slope beach, and exploitation construction cost is low, and having higher Strength and Dformation modulus after compacting, is the good natural materials constructing dam.But natural soft-clay material is due to the discreteness of grating, discontinuity and construction easy separation; impermeabilisation destroy and erosion ability poor; the domatic needs of sand-gravel dam arranges protective device; the domatic main employing cast in place concrete plate of current sand-gravel dam is protected; but there is working procedure complexity, better can not adapt to the problems such as dam deformation.
Utility model content
The utility model mainly solves technical problem existing in prior art, thus provides a kind of working procedure simple, better can adapt to dam deformation, discharge the sand-gravel dam slope protection device of dam internal water accumulation fast.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Sand-gravel dam slope protection device of the present utility model, comprise be laid on sand-gravel dam domatic on multiple concrete blocks, each described concrete block centre position is provided with a drain hole, is embedded with pvc pipe, is filled with stone in described pvc pipe in described drain hole.
Further, be also provided with geotextiles between described pvc pipe and drain hole, described geotextiles is coated on the external surface of described pvc pipe.
Further, the shape of described concrete block is hexagon.
Further, the shape of described drain hole is circular, and its size and described pvc pipe adapt.
Compared with prior art, the utility model has the advantage of: by arranging drain hole, pvc pipe and stone in concrete block, water in dam can be discharged in time, preventing inverse osmosis to the destruction of dam slope.Meanwhile, the mode of polylith concrete block splicing can adapt to dam deformation preferably, prevent cracking destruction, and concrete block can carry out before construction, has batch machining prefabricated, and site operation speed is fast, is convenient to the advantages such as maintenance or replacing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of sand-gravel dam slope protection device of the present utility model;
Fig. 2 is the structural representation of the concrete block of sand-gravel dam slope protection device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1-2; sand-gravel dam slope protection device of the present utility model, comprise be laid on sand-gravel dam domatic on multiple concrete blocks 1, each concrete block 1 centre position is provided with a drain hole 2; be embedded with pvc pipe 3 in drain hole 2, in pvc pipe 3, be filled with stone 4.Water in dam, by arranging drain hole 2, pvc pipe 3 and stone 4 in concrete block 1, can be discharged, prevent inverse osmosis to the destruction of dam slope by the utility model in time.Meanwhile, the mode that polylith concrete block 1 splices can adapt to dam deformation preferably, prevent cracking destruction, and concrete block 1 can carry out before construction, has batch machining prefabricated, and site operation speed is fast, is convenient to the advantages such as maintenance or replacing.
Preferably, be also provided with geotextiles between pvc pipe 3 and drain hole 2, geotextiles is coated on the external surface of pvc pipe 3, can prevent the fine grained taken away during draining in sand gravel, occur that dam slope damages.The shape of concrete block 1 is hexagon, also can adopt other splicing shapes, as square etc.More tight in order to make drain hole 2 and pvc pipe 3 coordinate, the shape of drain hole 2 is circular, and its size and pvc pipe 3 adapt.
Above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
