Description

Water drop vertical shaft of reservoir spillway

Technical Field

The utility model relates to a water conservancy construction field specifically is a reservoir spillway drop shaft.

Background

The reservoir spillway is a building for discharging flood, when the water level in the reservoir exceeds the safety limit, water flows out from the spillway to the downstream, the reservoir dam is prevented from being damaged, and the reservoir spillway is an important building related to the safety of the reservoir dam. The spillway is used for releasing flood which cannot be contained in planned reservoir capacity, and ensures the safe open type of dam body or the spillway water release structure with a breast wall water inlet. Spillways are generally not frequently operated, but are important buildings in reservoir hubs. Spillways are classified into normal spillways and extraordinary spillways according to flood discharge standards and operation conditions. The former is used to discharge design floods and the latter is used to discharge extraordinary floods. According to the position, the river bed type spillway is divided into a river bed type spillway and a shoreside spillway.

At the end of the spillway, energy dissipation and impact prevention measures are often required to prevent water flow from scouring. The conventional energy dissipation and impact prevention measures are long in length, large in width and large in occupied area, and when the land is limited, the arrangement is difficult, so that the scheme of the drop shaft is provided.

SUMMERY OF THE UTILITY MODEL

The utility model provides a reservoir spillway drop shaft has solved the terminal energy dissipation scour protection measure area's of present spillway great problem.

In order to achieve the above object, the utility model provides a following technical scheme:

The utility model provides a reservoir spillway drop shaft, includes the drop shaft, one side of drop shaft is equipped with the spillway, the opposite side of drop shaft is equipped with the box culvert, the drop shaft is equipped with the wall of a well all around, the box culvert is equipped with the expansion joint with the junction of drop shaft, be equipped with the waterstop in the expansion joint.

As an optimal technical scheme of the utility model, the spillway is close to the bottom arc setting of the one end of drop shaft.

As an optimized technical scheme of the utility model, the height that highly is less than spillway of box culvert.

As an optimized technical scheme of the utility model, the wall of a well is made by reinforced concrete.

As an optimized technical scheme of the utility model, the box culvert is made by reinforced concrete.

The utility model discloses have following useful part: the utility model discloses a set up the drop shaft to can carry out the energy dissipation to the terminal exhaust water of spillway, link up spillway and low reaches water outlet system, satisfy energy dissipation scour protection requirement, practice thrift the land used.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

Example 1

Referring to fig. 1-3, a water fall shaft of a reservoir spillway comprises a water fall shaft 1, wherein a spillway 4 is arranged on one side of the water fall shaft 1, a box culvert 2 is arranged on the other side of the water fall shaft 1, a shaft wall 5 is arranged around the water fall shaft 1, an expansion joint is arranged at the joint of the box culvert 2 and the water fall shaft 1, a water stop 3 is arranged in the expansion joint, the bottom of one end, close to the water fall shaft 1, of the spillway 4 is arc-shaped, and the height of the box culvert 2 is lower than that of the spillway 4.

Example 2

Referring to fig. 1-3, the other contents of the present embodiment are the same as embodiment 1, except that: the well wall 5 is made of reinforced concrete, and the box culvert 2 is made of reinforced concrete.

The utility model discloses in the implementation process, rivers fall to drop shaft 1 behind the end of spillway 4 in to carry out the energy dissipation to water, slow down its impulsive force, then water continues to discharge in flowing into box culvert 2 from drop shaft 1.

The utility model discloses a set up drop shaft 1 to can carry out the energy dissipation to 4 terminal exhaust waters of spillway, link up spillway 4 and low reaches water outlet system, satisfy energy dissipation scour protection requirement, the saving land.

Finally, it should be noted that: 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 described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
