Background
Along with the development of hydropower in more and more depth in the world, hydropower resources with good project economic indexes and good natural conditions are less and less, the project economic indexes are relatively poor, the construction conditions are poor, and remote hydropower resource points in the region are more and more emphasized. In order to improve the economic indexes of the projects and meet specific requirements abroad, for example, certain countries require that flood discharge buildings cannot adopt gate control, and a more flexible flood discharge scheme is generally required to be researched, so that the flood discharge safety can be ensured, and the total investment of the projects can be reduced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the water blocking and draining structure is flexible in arrangement and good in flood discharge effect.
The technical scheme adopted for solving the technical problems is as follows: a water retaining and draining structure comprises a water retaining dam provided with a spillway, and further comprises an overflow enhancement system, wherein the overflow enhancement system is arranged at the top of the spillway; during overflow flood discharge, the overflow enhancement system can increase the flow of overflow flood discharge.
Further, the overflow enhancement system is a broken line water retaining weir sequentially arranged at the top of the overflow flood way along the width direction of the river way; in the overflow flood discharge process, the overflow flood discharge length of the overflow flood discharge through the broken line water retaining weir is the sum of the lengths of the weir bodies of all the sections of the broken line water retaining weir.
The preferred mode of the scheme is that the broken line water-retaining weir comprises a plurality of sections of water-retaining thin-wall sub-weirs which are integrally formed, and the sections of water-retaining thin-wall sub-weirs are sequentially connected into a whole along the width direction of the river channel.
Furthermore, at least one overflow groove is respectively arranged on the upper side of each section of the water retaining thin-wall weir, and the elevation of the bottom of each overflow groove is matched with the elevation of the water surface of the normal water storage level.
The preferable mode of the scheme is that a flip bucket is further arranged on the inner side of the output tail end of the spillway.
Further, the projection of the spillway on the side wall is in a soup ladle shape with a hook head.
The utility model has the advantages that: this application sets up one set and overflows the enhancement system through increasing on the current manger plate dam that is provided with the spillway to with this overflow enhancement system arrange at the top of spillway, realize playing the effect of manger plate retaining when not needing the overflow flood discharge, when upstream catchments and increases and need the overflow flood discharge, overflow the flow that the flood discharge was increased through this overflow enhancement system, reach the purpose that improves the flood discharge effect. Because the overflow enhancement system of this application is on the top of direct arrangement spillway to can improve the flexibility that manger plate, overflow flood discharge structure arranged, can guarantee flood discharge safety, can reduce the total investment of project again.
Drawings
Fig. 1 is a schematic plan view of the water blocking and draining structure of the present invention;
fig. 2 is a sectional view of fig. 1 through 1.
Labeled as: the overflow spillway comprises an overflow spillway 1, a water retaining dam 2, an overflow enhancement system 3, a water retaining thin-wall sub-weir 4 and a flip bucket 5.
Detailed Description
As shown in fig. 1 and fig. 2, the above technical problems in the prior art are solved, and the utility model provides a water blocking and draining structure with flexible arrangement and good flood discharge effect. The water blocking and draining structure comprises a water blocking dam 2 provided with an overflow spillway 1, and further comprises an overflow enhancement system 3, wherein the overflow enhancement system 3 is arranged at the top of the overflow spillway 1; during spills, the flow of spills is increased by said spill enhancement system 3. This application sets up one set and overflows the enhancement system through increasing on the current manger plate dam that is provided with the spillway to with this overflow enhancement system arrange at the top of spillway, realize playing the effect of manger plate retaining when not needing the overflow flood discharge, when upstream catchments and increases and need the overflow flood discharge, overflow the flow that the flood discharge was increased through this overflow enhancement system, reach the purpose that improves the flood discharge effect. Because the overflow enhancement system of this application is on the top of direct arrangement spillway to can improve the flexibility that manger plate, overflow flood discharge structure arranged, can guarantee flood discharge safety, can reduce the total investment of project again.
The purpose of arranging the overflow enhancement system in the above embodiment is mainly to increase the discharge amount when overflow flood discharge is needed, at this time, the overflow enhancement system may have various structures, but in order to reduce the investment to the maximum extent, and also to ensure the overflow flood discharge effect, and at the same time, to facilitate the construction, the overflow enhancement system 3 described in this application is a broken line water-retaining weir sequentially arranged at the top of the overflow flood road along the width direction of the river; in the overflow flood discharge process, the overflow flood discharge length of the overflow flood discharge through the broken line water retaining weir is the sum of the lengths of the weir bodies of all the sections of the broken line water retaining weir. At this time, the broken line water-retaining weir preferably comprises a plurality of sections of water-retaining thin-wall sub-weirs 4 which are integrally formed, and the sections of water-retaining thin-wall sub-weirs 4 are sequentially connected into a whole along the width direction of the river channel. Correspondingly, in order to improve the overflow capacity to the maximum extent, at least one overflow groove is respectively arranged on the upper side of each section of the water retaining thin-wall sub-weir 4, and the elevation of the bottom of each overflow groove is adapted to the elevation of the water surface of the normal water storage level.
Furthermore, in order to reduce the erosion of the river channel caused by the downward flow of water, a flip bucket 5 is further arranged on the inner side of the output end of the spillway 1. At this time, the projection of the spillway 1 on the side wall is in a soup ladle shape with a hook head.
In conclusion, the dam constructed by adopting the water retaining and draining structure provided by the application has the following advantages,
the application provides a simple structure, fender drainage structure that flood discharge ability is strong, and the leading principle is, increases a broken line type thin wall construction in conventional overflow weir top, utilizes this kind of thin wall construction manger plate, when the water level is higher than the thin wall construction top, from thin wall construction top flood discharge. At the moment, the flow of the thin-wall structure can be calculated according to the thin-wall weir, and the width of the weir top is the total length of the broken line. This configuration allows for a narrower weir width to be used when dumping the same flow. The problem that the width of a weir needs to be increased by enlarging and digging towards two banks in part of projects due to insufficient overflow width is avoided. The engineering investment can be saved.
