The town river levee structure comprises a plurality of fixed foot planting sections 1, wherein each fixed foot planting section 1 comprises a soil retaining body 2 and a fixed foot body 3, and the lower end of the soil retaining body 2 is fixedly connected with the fixed foot bodies 3. A sewage intercepting pipe 4 is arranged in the foot fixing body 3 and is connected with a town sewage pipeline through the sewage intercepting pipe 4, so that the town sewage can be conveniently and intensively treated. Soil filling cavities 5 are formed in one side of the soil retaining body 2 and the upper end of the foot fixing body 3, planting soil 6 is filled in the soil filling cavities 5, and the planting soil 6 is used for planting aquatic plants.

During construction, the sewage intercepting pipe 4 is laid along the original vertical grout or concrete retaining wall of the revetment, and the sewage intercepting pipe 4 is wrapped by concrete to form the fixing foot body 3. The solid foot bodies 3 meet the design requirements of pipelines of the sewage interception pipes 4, meanwhile, the impact resistance of the river channel needs to be considered, the scouring depth is calculated by parameters such as water flow speed, and the like, and the foundation bed elevation meets the condition that the foundation bed elevation is arranged below the calculated maximum scouring depth by 0.5-1.0 m, so that the solid foot bodies 3 can be ensured to play a role in stabilizing the existing river channel retaining wall 14.

In order to prevent the sewage interception pipe 4 from being affected by uneven settlement, the structural foundation bottom needs to be tamped firstly, and a 15-20 cm gravel cushion layer 9 is arranged, namely the gravel cushion layer 9 is arranged below the foot fixing body 3 to support the foot fixing body 3. Meanwhile, a tamping layer 8 is arranged below the broken stone cushion layer 9 so as to further prevent the influence of uneven settlement on a sewage interception pipe in the foot fixing body.

It can be understood that, when the structure of the embodiment is built, the foundation is firstly tamped to form the tamped layer 8, and then the gravel cushion layer 9 is laid on the tamped layer 8; after the gravel cushion layer 9 is laid, the sewage intercepting pipe 4 is erected on the gravel cushion layer 9 so as to lay a pipeline; after the pipeline is laid, concrete is coated to form the solid legs 3. Therefore, the fixing foot body 3 is not only concrete wrapped outside the pipe network, but also is a part of the design of the pipe network of the sewage interception pipe 4, and the structure of the fixing foot body also meets the relevant requirements of the relevant regulation and specification of outdoor drainage.

The soil retaining body 2 is a concrete wood-like pile or pebble to further enhance the ornamental value of the river levee, and in the embodiment, the soil retaining body 2 is a concrete pine-like pile. Specifically, the concrete pine-like pile is pre-buried in the foot fixing body 3, and is integrally fixed and formed when the foot fixing body 3 is poured; the diameter of the concrete imitation pine board is 10-15 cm, the pile top elevation is higher than the perennial water level by 50-70 cm, and the burial depth in the foot fixing body 3 is determined through structural calculation.

The planting soil 6 is provided above the leg body 3, and is held between the soil retaining body 2 and the river retaining wall 14 by the soil retaining body 2. In order to ensure the growth of plants, the thickness of the 6 soil layers of the planting soil is more than or equal to 40 cm. The aquatic plant can be selected from herba Oenanthes Javanicae, herba Alii Fistulosi, etc.

A hydrophilic viewing platform 10 is arranged between two adjacent foot fixing planting sections 1, and the hydrophilic viewing platform 10 is provided with inspection wells 11 so as to meet the requirement that the inspection wells need to be arranged at intervals along the pipeline of the sewage intercepting pipe 4.
