The step 2 comprises the following steps:

the first step is as follows: and the sludge in the riverbed between the waver and the lower cofferdam is cleaned and the riverbed is dug to the designed elevation. Because the impermeable cover is needed to be arranged at the upstream of the wavelike body, the seepage path is increased, and the base permeation slope drop is reduced. The anti-seepage pavements have certain thickness, so that a section of riverbed is dug downwards according to design requirements to balance the space of the riverbed occupied by the anti-seepage pavements, and the condition of lifting the riverbed is avoided. Similarly, because the anti-impact body is required to be arranged at the downstream of the wavelike body, the downstream riverbed of the wavelike body is dug according to the design requirement so as to balance the space of the riverbed occupied by the anti-impact body, and the wavelike body downstream riverbed is prevented from being lifted.

The second step is that: and (4) cleaning the sludge on the overflow surface, the water-facing surface and the wavetop of the wavebody. Sludge on the object of the waver needs to be removed due to poor stability.

On one hand, the shoveling part of the wave top and the overflow surface removes the corroded and damaged parts on the wave top and the overflow surface so as to improve the stability after reinforcement; on the other hand, the method avoids the problem that the elevation of the wavetop or the elevation of an overflow surface is directly increased on the original wavelike body, so that new contradiction is caused by the increase of the wavetop, such as the problem of increasing upstream flooding.

And step 3: an anti-seepage cover is arranged between the wavelike body and the upper cofferdam and is used for increasing seepage path and reducing the wavelike base seepage slope. The impermeable cover can be made of reinforced concrete by pouring.

And 4, step 4: and an anti-impact body is arranged between the wavelike body and the lower cofferdam. The shock-proof body plays the role of energy dissipation and shock prevention, and the water accumulated at the upstream of the wave-like body can raise the water level difference between the upstream and the downstream, thereby increasing the damage to the downstream riverbed.

The second step is that: and pouring reinforced concrete on the wavelike top, the near water surface and the overflow surface after the anchor bars are implanted.

Step 6: a plurality of energy dissipation platforms are poured on the overflow surface after concrete is poured, the energy dissipation platforms are sequentially arranged in a step shape, and an energy dissipation groove is formed between every two adjacent energy dissipation platforms. Several rows of energy dissipation grooves are added on the overflow surface of the wavelike body, thus not only enhancing the integral structural performance of the wavelike body, but also eliminating partial water flow energy in advance, thus playing a certain role in protecting the downstream riverbed and wavelike body. And when the small water amount overflows, the energy dissipation platform can form a waterfall landscape.

Furthermore, when the energy dissipation table is poured, a groove can be reserved on the energy dissipation table to communicate two adjacent energy dissipation grooves. The groove can be used as a fishway to facilitate the tracing migration of fishes.

Adopt the utility model provides a reinforcement method, make full use of original water and wavelength, both can solve seepage, damaged problem, save the investment again greatly. In the reinforcing process, as the mud masonry stone of the original wavelike top part and the overflow surface part is chiseled firstly and then the reinforced concrete is poured, the elevations of the wavelike top and the overflow surface are not increased, the upstream flooding is not increased, and the contradiction is not newly increased. The seepage-proof covering and the scour prevention are respectively arranged at the upstream and the downstream of the waver, so that the upstream and the downstream riverbeds can be effectively protected, and the waver can be protected. The energy dissipation groove is additionally arranged on the overflow surface of the waver, so that the integral structural performance of the waver is enhanced, partial water flow energy can be eliminated in advance, and a waterfall landscape can be formed when small water flows over the waver.
