Description

A flood discharge channel for water conservancy projects

technical field

The utility model relates to the field of water conservancy engineering, in particular to a flood discharge trough for water conservancy engineering.

Background technique

The spillway is an open type or an overflow discharge structure with breast wall water inlet used to vent the flood that cannot be accommodated by the planned reservoir to ensure the safety of the dam body. It generally does not work frequently, but it is an important building in the reservoir hub. things. According to flood discharge standards and operating conditions, the flood discharge channels are divided into normal flood discharge channels and extraordinary flood discharge channels. The former is used to vent design floods, and the latter is used to vent extraordinary floods. According to its location, it can be divided into riverbed spillway and bank spillway.

In the event of an emergency flood, in order to discharge the flood, the spillway is often manually excavated. Because the soil on both sides of the newly dug spillway is soft, it is often washed away by the flood, and it needs continuous reinforcement, which is very time-consuming and labor-intensive. Certain dangers, in order to solve these problems, we propose a kind of spillway for water conservancy projects.

In order to achieve the above purpose, the utility model provides the following technical solutions: a flood discharge trough for water conservancy projects, including a plurality of steel structure plate groups, and bolts are used to fix the adjacent steel structure plate groups, and the steel structure plate groups include left inclined steel plate, right inclined steel plate, first connecting steel plate, second connecting steel plate and widened steel plate, the upper end surface of the left inclined steel plate, the left and right sides of the first connecting steel plate, the right side of the widened steel plate, the second connecting The right end surface of the steel plate and the upper end surface of the right inclined steel plate are provided with steel connecting plates of the same specification, and the rigid connecting plate on each part and its parts are integrally formed. The lower end surface of the left inclined steel plate and the widened steel plate The left side, the left side of the second connecting steel plate and the lower end surface of the right inclined steel plate are all provided with connecting grooves matching the rigid connecting plate. The left inclined steel plate, the first connecting steel plate, the widened steel plate, the second The connecting steel plate and the right inclined steel plate are connected sequentially from left to right through the insertion of the rigid connecting plate into the connecting groove, and are fixed by bolts.

Preferably, the left side of the first connecting steel plate and the right side of the second connecting steel plate are symmetrical inclined planes, and the angle between each plane and the horizontal plane is 45 degrees, which is different from the left inclined steel plate and the right inclined steel plate. Grooves can be formed when connected.

Preferably, the number of widened steel plates can be increased or decreased according to the actual width of the spillway, which can meet the needs of floodways with different widths, and the widened steel plates can be pre-installed to save time.

Preferably, the number of the left inclined steel plate and the right inclined steel plate is increased or decreased according to the height required by the actual flood discharge channel, and the flood discharge channel that can meet different height requirements can be pre-installed in advance to save time.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. The utility model has a simple structure, adopts a steel plate structure, can cope with the impact of floods, saves manpower, has good flood discharge performance, and is convenient to connect each part;

2. The utility model can increase or decrease the width and height of the flood discharge trough according to the scale of the flood discharge to meet the needs of use, and can pre-install components in advance, which can reduce the time for on-site assembly and improve construction efficiency.
