3. The lower slope protection structure is connected with the foot groove by adopting a reinforced concrete structure, and the frame grid is filled with concrete and is provided with drain holes, so that the stability of the protective structure below the foot groove is locally enhanced.
4. The reinforced concrete frame structure can extend deep below the dead water level, and cobbles are filled on the upper layer of the frame grid, so that the problem of attractive appearance when the underwater structure with low water level is exposed out of the water surface is solved.
In summary, the construction sequence of the shore protection engineering is to construct underwater feet protection firstly, then construct foot grooves, and finally construct the water slope protection. The underwater foot protection is water operation, the water slope protection elevation is higher, and the influence of the water level in the dead water period is smaller, so that the control node of the construction of the shore protection engineering is foot groove construction. The elevation of the foot groove is raised to divide the water slope protection into an upper slope protection structure and a lower slope protection structure, so that the influence of flood on construction can be reduced, the construction period can be saved in assembly construction, and the stability and the attractiveness of engineering can be ensured by adopting the structures of pouring concrete at the lower layer and paving cobbles at the upper layer in the precast reinforced concrete frame for the lower slope protection. The anti-interference device has the characteristics of safe structure, attractive appearance, convenience in construction and strong anti-interference capability.
