The conventional concrete landscape overflow dam adopts a triangular section commonly used in hydraulic buildings to ensure the stability of a foundation plane, is provided with a simple energy dissipation facility and has certain water harmony landscape and overflowing effects, but the conventional landscape concrete overflow dam has the defects of insignificant landscape, too obvious artificial trace, poor water flow energy dissipation effect and the like.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the problems that the landscape of the existing landscape overflow concrete dam cannot meet the requirements, the artificial trace is too heavy, the energy dissipation effect is poor and the like are solved.
The utility model discloses a realize like this:
a novel drop landscape overflow concrete dam structure comprises a dam body, wherein the dam body is arranged across the high water flow of a river channel; the upper side of the dam body is in a step form, a multi-stage drop landscape is formed in the water flow process, high-strength mortar is arranged on the contact surface of the upper side of the dam body and the water flow, landscape stones including upper landscape stones, middle landscape stones and lower landscape stones are arranged on the high-strength mortar, and a downstream large stone cushion layer is arranged close to the downstream of the dam body.
Wherein, the dam body adopts a combined rectangular section of an enlarged foundation.
Further, the high-strength mortar is poured to be 0.15-0.30 m thick.
Furthermore, the upper landscape stones are flatly laid on the steps on the upper side of the dam body, the lower landscape stones are flatly laid on the steps on the lower side of the dam body, and the middle landscape stones are connected and transited between the upper landscape stones and the lower landscape stones.
Further, the middle landscape slates are arranged in a downward inclined mode or a vertical mode.
Compared with the prior art, the utility model discloses a step overflow dam facing type has effectively increased the view slabstone range of arrangement on dam body surface, can form multistage drop view, promotes the view effect, and drop does the reinforcing simultaneously many times and to the energy dissipation effect of rivers, slows down the erodeing to the low reaches riverbed. The utility model discloses but wide application in the artifical view dam engineering in small-size river course.

Fig. 1 is a typical cross-sectional arrangement of the present invention;
fig. 2 is a typical cross-sectional layout two of the present invention.
The labels in the figures are: 1-a dam body; 2-downstream large rock mat layer; 3-upper landscape slates; 4-high strength mortar, 5-middle landscape flakelite, 6-lower landscape blockstone, 7-water flow, 8-first water drop position and 9-second water drop position.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model is suitable for a small-size river (retaining height is within 5 m), the artifical view overflow dam that has the energy dissipation effect. The novel drop landscape overflow concrete dam structure comprises a dam body 1, wherein the dam body 1 stretches over the gorgeous water flow on the river channel; the upper side of the dam body 1 is in a step form, a multi-stage drop landscape is formed in the water flow process, high-strength mortar 4 is arranged on the contact surface of the upper side of the dam body 1 and the water flow, landscape stones are arranged on the high-strength mortar 4 and comprise upper landscape stones 3, middle landscape stones 5 and lower landscape stones 6, and a downstream massive stone cushion layer 2 is arranged close to the downstream of the dam body 1.
In the specific implementation, the method comprises the following steps:
(1) the dam body 1 adopts a combined rectangular section of an enlarged foundation, so that the contact area of the foundation is increased, the foundation surface and the settlement of the dam body 1 can be effectively reduced, the stability of the dam body 1 is improved, and the stress state of the foundation is improved; the dam body 1 has a large reserved surface, so that arrangement and construction of landscape engineering are facilitated, and the dam body 1 spans the water flow 7 which is blocked on the river channel.
(2) The upper side of the dam body 1 adopts a step form, so that a multi-stage water drop landscape can be formed in the water flow process, the landscape effect in the water flow process is improved, meanwhile, the kinetic energy in the water flow process can be effectively eliminated in the multi-stage water drop process, and the downstream scouring is reduced.
(3) A downstream large rock cushion layer 2 with a certain length is arranged close to the downstream of the dam body 1 and is used as an energy dissipation cushion layer of the overflow landscape dam, so that the scouring of the water flow 7 to a downstream riverbed can be effectively reduced.
(3) And (3) pouring high-strength mortar 4 with the thickness of 0.15-0.30 m on the contact surface of the upper side of the dam body 1 and the water flow, wherein the construction surface treatment between the dam body 1 and the high-strength mortar 4 is practically required in the construction process, so that the tight connection between the dam body and the high-strength mortar is ensured. The surface of the high-strength mortar 4 can be laid with landscape rubbles according to landscape design requirements, preferably form a landscape rubble community with fluctuant, sparse and caused, and correspond to the dam front water retaining and dam surface water drop landscape to form an organic integral pattern. In addition, the contact surface between the high-strength mortar 4 and the landscape slates needs to be increased as much as possible during construction.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
