Abstract
The utility model discloses a cemented sand gravel buttress dam structure, which comprises a dam foundation and a dam body arranged on the dam foundation, wherein the dam body comprises an anti-seepage water-retaining layer and a group of buttresses which are arranged behind the anti-seepage water-retaining layer and are perpendicular to the axis of the dam body, and cemented sand gravel is filled between the buttresses; the seepage-proof water-retaining layer is a trapezoidal structure which becomes thinner gradually from the dam foundation to the dam top; the seepage-proofing water-retaining layer is formed by pouring reinforced concrete, and the gradient of the seepage-proofing water-retaining layer is between the gravity dam and the gelled gravel dam. The utility model discloses utilize multistage buttress to share upper reaches water pressure, reduce the atress that the dam body gelled gravel stone material to can reduce gelled sand gravel section, not only can reach the purpose of optimizing the engineering investment, reducible demand to dam site department sand gravel material reserves moreover improves the adaptability of gelled sand gravel dam.
Description
Technical Field
The utility model relates to a cemented sand gravel buttress dam structure belongs to hydraulic and hydroelectric engineering technical field.
Background
The cemented sand gravel dam is a new dam developed in recent years, and the section type is between the cemented sand gravel dam and the concrete gravity dam. The technology of constructing dam with gelled sand and gravel is a new type of dam technology developed on the basis of roller compacted concrete dam technology and face rockfill dam technology, and adopts sand and gravel materials (including sand, ballast, gravel and the like) added with a small amount of gelled materials to construct the dam, and uses high-efficiency earthwork transport machinery and compaction machinery to construct, so that the sand and gravel materials are changed into a continuous rigid body from a granular body. The technology for constructing the dam by the gelled sand gravel has the advantages of safety, reliability, high construction speed, simple process, good economy, reduction of environmental damage and the like.
Because of the local material utilization, the gelled gravel dam needs to utilize the riverbed gravel materials near the dam site, so that the dam type is not suitable for the area with less riverbed gravel material content (if the alternative material field is adopted, the economic advantage is lost). Meanwhile, the dam type is larger than a gravity dam, and more riverbed gravel materials are needed, so that the popularization of the dam type is limited in a plurality of riverbeds with less natural gravel material reserves.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cemented sand gravel buttress dam structure, this buttress dam rational utilization buttress bear the load, can reduce the slope of the upper and lower reaches dam slope of cemented sand gravel dam to reach and optimize the section, reduce the purpose of cemented sand gravel stone material quantity.
The technical scheme of the utility model: the utility model provides a cemented sand gravel buttress dam structure, includes the dam foundation and sets up the dam body on the dam foundation, the dam body include prevention of seepage water-retaining layer and set up behind prevention of seepage water-retaining layer and with a set of buttress that the dam body axis is perpendicular to was arranged, it has cemented sand gravel to fill between the buttress.
Furthermore, the seepage-proofing water-retaining layer is of a trapezoidal structure which becomes thinner gradually from the dam foundation to the dam top.
Furthermore, the seepage-proofing and water-retaining layer is formed by pouring reinforced concrete, and the gradient of the seepage-proofing and water-retaining layer is between the gravity dam and the gelled gravel dam.
Furthermore, the buttress is of a trapezoidal plate-shaped structure and is formed by pouring reinforced concrete.
Since the technical scheme is used, the utility model has the advantages of: the utility model discloses utilize multistage buttress to share upper reaches water pressure, reduce the atress that the dam body gelled gravel stone material to can reduce gelled sand gravel section, not only can reach the purpose of optimizing the engineering investment, reducible demand to dam site department sand gravel material reserves moreover improves the adaptability of gelled sand gravel dam.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail with reference to the accompanying drawings and examples.
The embodiment of the utility model provides a: the structural schematic diagram of the cemented sand gravel buttress dam structure is shown in fig. 1 and fig. 2, and the cemented sand gravel buttress dam structure comprises a dam foundation 1 and a dam body arranged on the dam foundation 1, wherein the dam body comprises an anti-seepage water-retaining layer 3 and a group of buttresses 2 which are arranged behind the anti-seepage water-retaining layer 3 and are perpendicular to the axis of the dam body, the buttresses 2 are in a trapezoidal plate-shaped structure and are formed by pouring reinforced concrete, and cemented sand gravel stones 4 are filled between the buttresses 2. The seepage-proof water-retaining layer 3 is a trapezoidal structure which becomes thinner gradually from the dam foundation to the dam top; the seepage-proofing and water-retaining layer 3 is formed by pouring reinforced concrete, and the gradient of the seepage-proofing and water-retaining layer is between the gravity dam and the gelled gravel dam.
The utility model discloses utilize multistage buttress 2 to share upper reaches water pressure, reduce dam body gelatinization sand gravel 4's atress to can reduce gelatinization sand gravel 4's section, not only can reach the purpose of optimizing the engineering investment, reducible demand to gelatinization sand gravel 4 reserves of dam site department improves gelatinization sand gravel dam's adaptability moreover.
