Specifically, taking the levee 60 of a certain reservoir area as a level 3 as an example, the flood standard is designed to be 50 years, the corresponding elevation is 35.33m (1985 national elevation standard, the same below), and the normal water storage level is 24.0 m. Before the reservoir is built, a dike road combination type is adopted, the elevation of a dike top road surface is 27.5m, the width of the dike top is 82m, a traffic road is arranged in the middle, and shops are arranged on two sides. In order to meet the flood control requirement, the top of the dike needs to be heightened by nearly 10 m. If the conventional earth dike is heightened, the two sides of the earth dike near the back water are set to be sloping according to the ratio of 1:2, the occupied land is 56m, a large amount of land is occupied, the width of the road surface at the top of the dike is greatly narrowed, and the commercial and traffic requirements cannot be met. Therefore, a multifunctional flood control wall integrating flood control, commerce and viaducts is adopted.
At the top of the dike combined with the prior dike, the depth of an excavation foundation pit is 3.2m close to the side close to water, a bottom plate 10 of the flood control wall is arranged, the width is 20m, the buried depth under the ground is 2.5m, the thickness of the bottom plate 10 is 0.6m, and the thickness is increased at the positions of the impervious wall 20 and the pier wall 50.
Pouring the pier wall 50, the impervious wall 20 and the soil partition plate 30 on the top of the pier wall 50 on the bottom plate 10. The pier walls 50 are positioned at two sides of the impervious wall 20, and the distance between the pier walls 50 is 10m, the length is 8.4m, the thickness is 0.8m, and the height is 6 m. The impervious wall 20 is 0.6m thick, the top elevation of the reinforced concrete structure is 36.8m, and the height is 1.5m higher than the designed flood level. The space between adjacent pier walls 50 can be used as a shop.
The pier wall 50 can be provided with door and window openings, but the flood wall is not provided with door and window openings, and shops on two sides are completely separated by the flood wall.
The pier 41 is arranged at the top of the pier wall 50 at intervals of 20m, the longitudinal beams and the groove beams of the bridge are installed, the bridge deck 43 is paved, and the anti-collision wall 44 is installed.
Along the direction of the bottom plate 10 of the impervious wall 20 close to the water side, a high-pressure jet impervious wall 70 with the wall thickness of 0.3m and the depth of 10.8m is arranged in the foundation and penetrates into the relative impervious bed 1m of the foundation so as to weaken the hydraulic connection between the inside and the outside of the dike and prevent the dike foundation from being damaged. Backfilling clay 80 and tamping the space at the top of the high pressure jet grouting impervious wall 70 combined with the bottom plate 10. The pit of the floor 10 is filled with backfill clay 80 to a design ground level of 27.5 m.
A gate 21 is arranged on the impervious wall 20 every 100-200 m along the longitudinal direction of the impervious wall 20. The width of the gate 21 is 8.8m, the gate is opened at ordinary times, when flood rises, people and property on the side close to the water are evacuated in advance, and the gate 21 is closed. The high-pressure jet grouting impervious wall 70, the impervious wall 20 and the gate 21 form a closed flood control system. The multifunctional flood control wall occupies less land, has high rigidity, integrates flood control, commerce and viaducts into a whole, and has a novel structure.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
