[0042] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0043] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention.

[0044] In order to widen the riverside road, the current plan to add pedestrian passages at the existing river channel is to widen the pedestrian trestle, that is, to build a new pedestrian trestle above the river. No matter it is a steel trestle, concrete trestle or wooden trestle, it is necessary to drive piles and erect piers in the river along the river retaining wall. As the supporting system of the trestle board, the piers of the trestle will encroach on the blue line of the river. In addition, the new trestle is separated from the old road, making traffic organization inconvenient.
[0045] The overhead power pipelines and some overhead weak-current pipelines on the side of the old road are tangled and disorderly. During the reconstruction of the old road, the "upward-downward conversion" of the overhead power lines and the relocation of the communication pipelines are also difficult problems that need to be urgently solved.
[0046] Reference Figure 1 and Figure 2The present embodiment proposes a multifunctional river retaining wall, comprising a cantilevered sidewalk slab 1 and a retaining wall body, wherein the retaining wall body comprises a vertical retaining wall 2 and a single-compartment pipe gallery 3; the top of the vertical retaining wall 2 is the cantilevered sidewalk slab 1, and the bottom is the single-compartment pipe gallery 3; in the present embodiment, the cantilevered sidewalk slab 1, the vertical retaining wall 2 and the single-compartment pipe gallery 3 are an integrally formed concrete structure.
[0047] The cantilevered sidewalk slab 1 is used to provide a pedestrian passage. In the widening scenario of the riverside road, the pedestrian passage is transferred from the outside of the river to the inside of the river. In this embodiment, the retaining wall body is used as a bridge pier to cantilever the sidewalk slab above the river, thereby meeting the pedestrian passage needs after the widening of the riverside road without encroaching on the river space.
[0048] Reference Figure 1 In this embodiment, the cantilevered sidewalk slab 1 and the vertical retaining wall 2 are arranged in a T shape. Figure 2 , the cantilevered sidewalk slab 1 includes a pedestrian area and a green area, and the pedestrian area includes a cantilevered area and a middle area;
[0049] Reference Figure 2 The middle area is located directly above the vertical retaining wall 2, and the side of the middle area close to the river channel is the cantilevered area, that is, the cantilevered area is suspended above the river channel, and the side of the middle area away from the river channel is the greening area.
[0050] The cantilevered area is determined according to the designed width of the road sidewalk, and the greening area is determined according to the designed width of the road greening area. This embodiment is beneficial to the anti-overturning stability of the overall structure by designing the greening area placed on the roadbed soil.
[0051] The vertical retaining wall 2 is a variable-section retaining wall, and the cross-section of the vertical retaining wall 2 is a trapezoid. In this embodiment, the vertical retaining wall 2 adopts a regular trapezoidal concrete structure, and the steel bars penetrate into the cantilevered sidewalk slab 1 and the single-cabin pipe gallery 3 to connect the three into an integrated structure;
[0052] In practical applications, those skilled in the art can determine the maximum width of the trapezoidal cross-section of the vertical retaining wall 2 according to the design moment load transmitted by the cantilevered sidewalk slab 1 .
[0053] Adopt the design concept of combining drainage and blocking:
[0054] The single-cabin pipe gallery 3 is fully waterproofed;
[0055] The bottom of the vertical retaining wall 2 is higher than the normal water level of the target river channel, and a first waterproof layer 35 is provided on one side of the vertical retaining wall 2 close to the target river channel;
[0056] Reference Figure 1 A drainage component is buried in the vertical retaining wall 2, and a sand and gravel filter layer 22 is also provided on the side of the vertical retaining wall 2 away from the river channel.
[0057] One end of the drainage assembly is arranged on a side of the vertical retaining wall 2 close to the river channel, and the other end is arranged on a side of the vertical retaining wall 2 away from the river channel;
[0058] The drainage assembly includes drainage pipes 21 distributed in a plum blossom pattern with a spacing of 30 to 50 cm. In this embodiment, drainage pipes 21 with a diameter of 10 cm are used.
[0059] The thickness of the sand and gravel filter layer 22 is 20-40 cm. In this embodiment, a 30 cm sand and gravel filter layer 22 is laid.
[0060] Reference Figure 1 and Figure 2 The single-compartment pipe gallery 3 has an inner cavity for storing 10kV power pipelines and communication optical cables. Those skilled in the art can determine the spatial size of the inner cavity according to the number of pipelines entering the gallery.
[0061] Reference Figure 1 The single-cabin pipe gallery 3 is a rectangular single-cabin pipe gallery 3 composed of a river-facing wall 31, a river-facing wall 32, a top plate 33 and a bottom plate 34;
[0062] The vertical retaining wall 2 is located directly above the river-facing wall 31, and the steel bars of the vertical retaining wall 2 penetrate into the river-facing wall 31;
[0063] The top plate 33 is higher than the normal water level of the target river channel. In actual application, roadbed soil will be filled above the top plate 33 to provide the overall structure with anti-overturning load.
[0064] The bottom plate 34 is lower than the riverbed of the target river channel, and a wall toe is provided on a side of the bottom plate 34 close to the target river channel. The distance between the bottom plate 34 and the riverbed is greater than or equal to a preset depth distance, which is set to 1 m in this embodiment.
[0065] In order to ensure the dryness inside the single-cabin pipe gallery 3, the single-cabin pipe gallery 3 is fully waterproofed. Figure 1 , specifically:
[0066] The outer side of the river-facing wall 31 is provided with a first waterproof layer 35;
[0067] The outer sides of the top plate 33, the river-side wall 32 and the bottom plate 34 are all provided with a second waterproof layer 36;
[0068] In this embodiment, the first waterproof layer 35 is a waterproof layer formed by applying a colored waterproof coating, and the second waterproof layer 36 is a waterproof layer formed by pasting a waterproof roll.
[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
