Abstract
The utility model discloses a construction structure for a water passing earth-rock dam. The construction structure comprises a trapezoid dam body built on a base rock face (or a cover layer). The trapezoid dam body is composed of earth-rock materials, a clay core wall and a filter material, wherein the clay core wall and the filter material are built among the earth-rock materials. A reinforcing cage protecting slope is built on the upstream dam face of the trapezoid dam body. The dam top and the downstream dam face of the trapezoid dam body are provided with a plurality of reinforcing concrete face plates. The reinforcing concrete face plates are connected into one to form a water passing face. The reinforcing concrete face plate on the bottom of the downstream dam face is provided with a water passing hole. The construction structure has the advantages of adopting the anti-scouring structure of a rock block gasket and the reinforcing concrete face plates arranged on the dam top and the downstream face, the reinforcing cage protecting slope arranged on the upstream dam body, and a concrete toe wall of the downstream dam foot, achieving the water passing function of the earth-rock dam, and being safe, economical and convenient to construct.

Technical field
The utility model relates to a kind of structure of constructing of over-flow earth-rock dam, belongs to the dam construction technique field.
Background technology
Earth and rockfill dam is historical the longest a kind of dam type, also is a kind of dam type that is most widely used during present world dam worker builds.The advantage of earth and rockfill dam is to gather materials on the spot, and can save the constructional materialss such as Shui Ni ﹑ steel, and cost is low, and is simultaneously simple in structure, is convenient to keep in repair and increase.Its dam body is native stone bulk solid structure, and the adaptive deformation ability is strong, and is low to foundation requirement, and construction is simple, convenient.
But existing dam body can not be crossed this obvious weakness of water, and dam crest in order to satisfy the flood discharge requirement, often need increase special release floodwatering facility in the engineering in case cross water and will exert an influence to safety of dam body, such as flood-discharge tunnel etc.Cross water if can realize the earth and rockfill dam dam body, with the great change of the function generation that makes earth and rockfill dam.
The utility model content
The purpose of this utility model is to provide the structure of constructing of over-flow earth-rock dam, can solve earth and rockfill dam and can not cross water problem.
The purpose of this utility model is achieved through the following technical solutions: a kind of over-flow earth-rock dam construct structure, comprise the trapezoidal dam body of building on bedrock surface, described trapezoidal dam body is comprised of earth and stone material and earth core and the filter material built between earth and stone material, built the reinforcing cage bank protection on the upstream dam facing of trapezoidal dam body, be provided with polylith steel concrete panel on the dam crest of trapezoidal dam body and the downstream dam facing, the steel concrete panel formation flow surface that links into an integrated entity, wherein, be provided with water hole on the steel concrete panel of downstream dam facing bottom.
Be provided with piece stone bed course between the dam crest of described steel concrete panel and trapezoidal dam body and the downstream dam facing.
Be provided with concrete toe wall on the base of dam of described trapezoidal dam body.
Adopt " Z " type joint to connect between the described steel concrete panel.
The beneficial effects of the utility model are: the structure that has increased dam crest and downstream dam facing piece stone bed course and steel concrete panel, upstream dam facing reinforcing cage bank protection, downstream base of dam concrete toe wall protection against erosion, realized that earth and rockfill dam crosses water function, had the characteristics of safety, economy, easy construction.

Fig. 1 is structural representation of the present utility model.
Wherein, 1-earth and stone material, 2-earth core, 3-filter material, 4-steel concrete panel, 5-reinforcing cage bank protection, 6-piece stone bed course, 7-concrete toe wall, 8-drain hole, 9-" Z " type joint, the 10-bedrock surface, the trapezoidal dam body of 11-, 21-upstream dam facing, 22-dam crest, 23-downstream dam facing.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Such as Fig. 1, a kind of over-flow earth-rock dam construct structure, comprise the trapezoidal dam body 11 of building on bedrock surface (or covering layer) 10, described trapezoidal dam body 11 is by earth and stone material 1 and build in earth core 2 and the filter material 3 of 1 of earth and stone material and form, built reinforcing cage bank protection 5 on the upstream dam facing 21 of trapezoidal dam body 11, reinforcing cage bank protection 5 makes trapezoidal dam body 11 have good stablizing, be provided with polylith steel concrete panel 4 on the dam crest 22 of trapezoidal dam body 11 and the downstream dam facing 23, among the figure, arrow is depicted as water (flow) direction, the steel concrete panel 4 formation flow surface that links into an integrated entity, make earth and rockfill dam have discharge capacity, wherein, be provided with water hole 8 on the steel concrete panel 4 of downstream dam facing 23 bottoms, drain hole 8 is arranged on steel concrete panel 4 lower positions, can get rid of the infiltration in the trapezoidal dam body 11, prevents that internal water pressure from producing jacking to steel concrete panel 4 and destroying.
Be provided with piece stone bed course 6 between the dam crest 22 of described steel concrete panel 4 and trapezoidal dam body 11 and the downstream dam facing 23, as the transition between steel concrete panel 4 and dam crest 22 and the downstream dam facing 23, the thickness of piece stone bed course 6 is 50cm～100cm.
Be provided with concrete toe wall 7 on the base of dam of described trapezoidal dam body 11, can prevent current to the washing away of base of dam, concrete toe wall 7 should place bedrock surface 10 or enter metastable basis, and the end face of concrete toe wall 7 is concordant with the earth's surface.
Adopt " Z " type joint 9 to connect between the described steel concrete panel 4, can prevent like this deformation effect that trapezoidal dam body 11 differential settlements produce steel concrete panel 4.
Utilize dump truck that earth and stone material 1, earth core 2 and filter material 3 are transported to construction storehouse face, adopt the vibrating roller grinding compacting, form trapezoidal dam body 11, the bottom of earth core 2 should enter bedrock surface 10 or relative impervious layer; At upstream dam body 21 reinforcing cage bank protection 5 is set afterwards, in steel concrete panel 4 bottoms piece stone bed course 6 is set, and build base of dam concrete toe wall 7, drain hole 8 can adopt at steel concrete panel 4 interior built-in pipes and form, wherein, filling of trapezoidal dam body 11 expects that index, placement grinding construction and degree of compaction etc. should satisfy the related request of earth and rockfill dam, and earth and stone material 1 can adopt the ballast of Project Areas excavation, and the thickness of earth core 2 and filter material 3 is determined according to height of dam; According to height of dam and inflow-rate of water turbine size, the thickness of the reinforcing cage bank protection 5 of upstream dam facing 21 is generally 50cm～120cm; The thickness of the steel concrete panel 4 of dam crest 22 and downstream dam facing 23 is 50cm～100cm; Array pitch 1.0m～1.5m between drain hole 8, the aperture is 50mm～100mm.
