[0034] See also Figure 1-Figure 4 Now, an empty box type flood wall provided by an embodiment of the utility model is described.
[0035] In one embodiment, an empty box type flood wall of the embodiment of the utility model comprises: a foundation bottom plate 5, a water-facing side wall 4, a water-receiving side wall 6, a top plate 12 and floor tiles 2. The foundation bottom plate 5 is arranged on the foundation 16; the lower side of the water-facing side wall 4 is connected to the foundation bottom plate 5; the bottom of the water-facing side wall 4 is provided with a drainage hole 11, and the drainage hole 11 communicates with the water-facing side river channel and the inside of the cavity 17; the lower side of the water-receiving side wall 6 is connected to the foundation bottom plate 5, and the water-receiving side wall 6 is symmetrically arranged with the water-receiving side wall 4, and the water-receiving side wall 6 is used to abut against the road surface 14 behind the wall, and the road surface 14 behind the wall is provided with a road drainage pipe 13; the two sides of the top plate 12 are respectively connected to the water-facing side wall 4 and the water-receiving side wall 6; a cavity 17 is formed between the foundation bottom plate 5, the water-facing side wall 4, the water-receiving side wall 6 and the top plate 12; and the floor tiles 2 are laid on the top plate 12.
[0036] like Figure 1 As shown, in this embodiment, the water-facing side wall 4 and the water-receiving side wall 6 are respectively arranged at the front and rear sides of the foundation slab 5, and the foundation slab 5 is a reinforced concrete structure. The thickness of the water-facing side wall 4 and the water-receiving side wall 6 is not less than 0.2m, and they are integrally cast with the top slab 12 to form a reinforced concrete box culvert structure. The concrete strength grade is not less than C30, and expansion joints are set every 10m on the flood wall, with a width of 2cm. The expansion joints are filled with polyethylene low-foaming caulking plates and water-swelling water-stopping rubber strips.
[0037] A hollow box flood wall of the utility model embodiment can reduce the weight of the wall by setting a cavity 17 structure in the wall, making the wall lighter and reducing the slope load, so that it can be built and used on a soft foundation, and greatly saves masonry materials, which is more economical.
[0038] The hollow box flood wall of the utility model embodiment is provided with drainage holes 11, so that flood water in the flood season can enter the cavity 17 of the flood wall through the drainage holes 11 at the bottom of the water-facing side wall 4, so as to achieve the balance of water pressure inside and outside the cavity 17 of the flood wall under different water level conditions, reduce the concentration of structural stress, and use the water in the cavity 17 to increase the overall deadweight of the flood wall, ensure the anti-slip and anti-tilt stability of the flood wall, and discharge the flood water from the cavity 17 into the river channel during the receding period, so as to reduce the deadweight. The hollow box flood wall of the utility model embodiment fully takes into account durability, economy and safety.
[0039] In this embodiment, an empty box-type flood wall is set at the edge of the embankment. The width of the foundation bottom plate 5 is not less than 0.7 times the retaining height. The height of the water-facing side wall 4 and the backwater side wall 6 is higher than the height of the design flood level 15. The depth of the foundation 16 is not less than 1m. If the base surface of the foundation 16 is anti-sliding and stable or the foundation stress does not meet the requirements of the specification, foundation treatment is required. The foundation 16 can be reinforced by replacing or adding pile foundations, which is convenient for construction. The replacement depth or pile foundation type depends on factors such as the height of the flood wall, the retaining height behind the wall, and the water level in front of the wall. The specific engineering design is determined by stable calculation.
[0040] Furthermore, an empty box-type flood wall of the present embodiment also includes a vertical drainage pipe 10, and a lateral drainage ditch 9 is provided on one side of the floor tile 2 close to the backwater side wall 6; the upper end of the vertical drainage pipe 10 is connected to the lateral drainage ditch 9, and the lower end is connected to the urban road drainage pipe 13. The accumulated water on the floor tile 2 is discharged into the road drainage pipe 13 through the lateral drainage ditch 9 and the vertical drainage pipe 10. Therefore, preferably, the floor tile 2 is inclined to one side of the lateral drainage ditch 9 to facilitate the accumulated water to flow quickly into the lateral drainage ditch 9 along the slope, and the slope can be set to 2%. The vertical drainage pipe 10 and the drainage hole 11 can be pre-buried and preset with PVC or other material pipes, with a hole diameter of 15 to 20 cm and a horizontal hole spacing of 3 to 5 m, which can be adjusted according to the size of the flood wall.
[0041] Furthermore, the hollow box type flood wall of this embodiment further comprises a slope protection 8, one end of which is connected to the base plate 5. Specifically, the slope protection 8 is a Reno slope protection with a thickness of not less than 0.3m, and a geotextile (not less than 230g / cm 2 ). In this way, the water-facing side of the flood wall can be planted with Reno slope protection, the drainage system is well concealed, and the ecological landscape effect is better.
[0042] Furthermore, the bottom side of the foundation slab 5 of this embodiment is provided with a trapezoidal tooth groove, and the trapezoidal tooth groove depends on factors such as the height of the flood wall, the height of the retaining wall behind the wall, and the water level in front of the wall, and the specific engineering design is determined by stable calculation. When installing the foundation slab 5, the upper side of the foundation 16 is first dug into an outward convex trapezoidal shape matching the trapezoidal tooth groove, and then the foundation slab 15 is placed on the foundation 16. In this way, the connection between the foundation slab 5 and the foundation 16 is in a trapezoidal tooth groove shape, which can increase the anti-slip force of the foundation slab 5 and make it more stable on the foundation 16.
[0043] Furthermore, the hollow box flood wall of this embodiment further includes a buffer layer 7, which is disposed between the base slab 5 and the foundation 16. The buffer layer 7 can be formed by pouring C15 plain concrete. A buffer zone is formed between the base slab 5 and the excavated fill of the foundation 16 by the buffer layer 7.
[0044] Furthermore, battlements 1 are also provided on the top of the water-facing side wall 4 and the water-retaining side wall 6 of the present embodiment. Battlements 1 can be built with antique bricks. Furthermore, wall tiles 3 are also affixed to the exposed surfaces of the water-facing side wall 4 and the water-retaining side wall 6 of the present embodiment. Wall tiles 3 can be made of antique city wall tiles. Furthermore, floor tiles 2 can be made of antique blue bricks, and the thickness of the antique blue bricks can be 12 cm. The selection of antique blue bricks and antique city wall tiles can fully consider the local ancient cultural humanities and keep the color difference basically consistent. Specifically, after the water-facing side wall 4 and the water-retaining side wall 6 are cast and reach the design strength, the top antique brick battlements 1, the antique city wall bricks 3 on the facade, and the antique blue brick floor tiles 2 on the hollow box structure concrete top plate 12 can be constructed. In this way, the flood wall of this embodiment has an appearance of an antique city wall, the facade is tiled with ancient city wall bricks 3, and the top city wall battlement 1 is brick-built, taking into account the antique humanistic ecological landscape and citizens' leisure and sightseeing, and is easy to repair.
[0045] Traditional flood walls often only focus on flood control performance requirements, but ignore the beautifying effect of flood walls on the riverside landscape. The appearance is rigid and stereotyped, the landscape effect is poor, and it is not conducive to tourists' experience and appreciation of the river scenery. The empty box flood wall of this embodiment is not only light in structure, economical and reasonable, and occupies a small area, but also has multiple functions such as flood control safety, antique cultural landscape, and citizen leisure.
[0046] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
