Abstract

The utility model provides a kind of broken line type weir that can reduce upstream hammed water height, with light thin-walled weir structure provided by the utility model instead of original thick and heavy weir structure, compared with traditional weir, its structure type is simple, construction technology and construction quality control are convenient, can accelerate construction progress;Because of structure optimization, reduce concrete amount in the construction process, economical environment-protective there are good application conditions as the operation of low weir dam;The broken line type weir provided by the utility model for reducing upstream hammed water height is designed using broken-line type, so that impact obtains obvious energy dissipating mutually when upland water overcurrent, flow rate of water flow is significantly reduced, downstream river course is reduced and washes away, reduce the construction of downstream dissipator of energy facility;In addition, increasing flow section using broken-line type structure, to reduce the upstream depth of water, upstream hammed water is reduced, upstream dyke crest level is effectively reduced, saves construction investment.

Description

A kind of broken line type weir reducing upstream hammed water height
Technical field
The utility model belongs to hydraulic and hydroelectric engineering technical field, can reduce upstream hammed water height more particularly, to one kind Broken line type weir.
Background technique
Traditional weir design common form is single, only plays water storage, irrigation etc. under the premise of meeting flood control substantially and makees With not in view of landscape and ecological requirements.And country vigorously advocates low-carbon emission reduction, energy conservation and environmental protection in recent years, therefore is meeting Under the use premise of flood control safety, it is necessary to can be reduced concrete amount using one kind, improve ecological, landscape novel weir Dam.
Utility model content
The purpose of this utility model is that upstream hammed water can be reduced by providing one kind for the deficiencies in the prior art The broken line type weir of height.
For this purpose, the above-mentioned purpose of the utility model is achieved through the following technical solutions:
A kind of broken line type weir reducing upstream hammed water height, the broken line type weir for reducing upstream hammed water height Including positive weir section and side weir section, the positive weir section includes the positive weir section of the positive weir section in upstream and downstream, and the positive weir section in upstream is arranged in The upstream of overcurrent flowing water, the positive weir section in downstream are arranged in the downstream of overcurrent flowing water, and the side weir section is for connecting upstream Zheng Yan The positive weir section of section and downstream is to form broken line type weir.
While by adopting the above technical scheme, the utility model can also be used or be combined using further below Technical solution:
Preferably, the broken line type weir lower part for reducing upstream hammed water height is equipped with bottom plate, and the bottom plate is for holding Carry positive weir section and side weir section.
Preferably, the positive weir section and/or side weir section are straightway.
Preferably, the side weir section is arc section, and the center of circle of arc section is arranged in downstream side.
The utility model provides a kind of broken line type weir that can reduce upstream hammed water height, and use is provided by the utility model Light thin-walled weir structure is instead of original thick and heavy weir structure, and compared with traditional weir, structure type is simple, construction Technology and construction quality control are convenient, can accelerate construction progress;Because structure optimization reduces concrete in the construction process Dosage, economical environment-protective have good application conditions as the operation of low weir dam;It is provided by the utility model to reduce upstream hammed water The broken line type weir of height is designed using broken-line type, so that impact obtains obvious energy dissipating mutually when upland water overcurrent, it is significant to drop Low flow rate of water flow reduces downstream river course and washes away, reduces the construction of downstream dissipator of energy facility;In addition, using broken-line type structure Flow section is increased, to reduce the upstream depth of water, reduces upstream hammed water, is effectively reduced upstream dyke crest level, is saved Construction investment is saved;Broken line type weir beautiful shape provided by the utility model has beautiful cascade effect, to build Landscape effect;Broken line type weir provided by the utility model can be to the ecology in region by the adjusting to silt, water flow Environment and ecological quality are improved and are administered accordingly, thus development of enhancing harmony between man and nature, and then the life to periphery Bigger contribution is made in state, economy and social development.
Detailed description of the invention
Fig. 1 is the horizontal layout for the broken line type weir that one kind provided by the utility model can reduce upstream hammed water height Figure;
Fig. 2 is the cross-sectional view in the direction A-A in Fig. 1;
In figure: the positive weir section in the upstream 111-;The positive weir section in the downstream 112-;120- side weir section;2- bottom plate.
Specific embodiment
The utility model is described in further detail referring to the drawings and specific embodiments.
A kind of broken line type weir reducing upstream hammed water height, including positive weir section and side weir section 120, positive weir section includes upper The positive weir section 112 of positive weir section 111 and downstream is swum, the positive weir section 111 in upstream is arranged in the upstream of overcurrent flowing water, downstream 112 cloth of positive weir section It sets in the downstream of overcurrent flowing water, side weir section 120 is for connecting the positive weir section 112 of the positive weir section 111 in upstream and downstream to form broken line type Weir.
The broken line type weir lower part that upstream hammed water height can be reduced is equipped with bottom plate 2, bottom plate 2 for carry positive weir section (including 112) and side weir section 120 the positive weir section of the positive weir in upstream section 111 and downstream.
In the present embodiment, positive weir section and/or side weir section 120 are straightway;Certainly in other examples, side weir section 120 may be set to be arc section, and the center of circle of arc section is arranged in downstream side, so that flow section is further increased, Reduce the upstream depth of water, reduces upstream hammed water, be effectively reduced upstream dyke crest level, cost saving.
Above-mentioned specific embodiment is used to illustrate the utility model, the only preferred embodiment of the utility model, and It is not to limit the utility model, it is practical new to this in the spirit and scope of protection of the claims of the utility model Any modification, equivalent substitution, improvement and etc. that type is made, both fall within the protection scope of the utility model.
