AI Technical Summary
In the old city area, buildings are dense and rainwater and sewage separation is difficult to transform. The demand for existing revetment reinforcement and sewage interception and discharge is increasing. However, traditional methods will damage the existing structure and land resources are scarce, making it difficult to achieve effective trenchless construction and good sewage interception and discharge effects.
The reinforced revetment structure consists of precast piles, breast walls, retaining walls, sewage main pipes, and backfill. Precast piles are driven on the outside of the existing revetment and connected to the breast walls and retaining walls. Sewage main pipes and interceptor pipes are installed, and the sewage main pipes are covered with soil to cover them, achieving trenchless construction. Green plants are planted on the inside of the retaining walls, and sewage is collected by sewage wells, forming an integrated design.
The reinforcement will be carried out without damaging the existing riverbank structure, thereby achieving the effects of sewage interception and discharge, improving the landscape along the river, and preventing structural loss through soil covering and greening, thus reducing the impact on the current situation.

[0013] 3) sewage main pipe top is provided with covering soil, load green plants, improve the landscape along the river. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is standard segment structure schematic view in the embodiment of the utility model.
[0015] Figure 2 It is sewage well segment structure schematic view in the embodiment of the utility model. DETAILED DESCRIPTION
[0016] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in combination with the drawings and embodiment, and the utility model is further detailed.The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0017] In the embodiment, the land side is the inner side, and the river side is the outer side.
[0018] As shown in Figure 1 , Figure 2 The utility model embodiment proposes a reinforced revetment structure with sewage interception and discharge function, comprising prefabricated pile 1, breast wall 2, retaining wall 3, sewage main pipe 4, sewage interception pipe 5, covering soil 6.
[0019] The prefabricated pile 1 is punched into the soil outside the existing revetment, and the top of each prefabricated pile 1 is connected with the breast wall 2 that is cast in situ.
[0020] The breast wall 2 is integrally connected with the retaining wall 3 that is cast in situ on the outer side above the breast wall 2, and the sewage main pipe 4 is arranged on the breast wall 2 above the breast wall 2 along the river direction on the inner side of the retaining wall 3, the sewage main pipe 4 is connected with the sewage outlet on the existing revetment through the sewage interception pipe 5, and the covering soil 6 is backfilled on the breast wall 2 above the breast wall 2 on the inner side of the retaining wall 3 to press the sewage main pipe 4.
[0021] The reinforced revetment structure proposed in the application can reinforce the existing revetment by punching the prefabricated pile 1 outside the existing revetment and erecting the breast wall 2 and the retaining wall 3 that are cast in situ, and can realize trenchless construction and have little influence on the existing situation, the sewage outlet on the existing revetment is connected with the sewage main pipe through the sewage interception pipe to realize source control and sewage interception along the revetment, the far end of the sewage main pipe 4 can be connected with the urban sewage treatment pipe network to send the collected sewage to the sewage treatment plant for treatment, avoiding direct discharge of sewage into the river, and the covering soil 6 is used to press the sewage main pipe 4 to prevent the sewage main pipe from floating.
[0022] Further, the precast piles 1 are provided in two rows; the breast wall 2 is in inverted L shape, the vertical part of which is connected with the outer row of precast piles 1, and the horizontal part of which is connected with the inner row of precast piles 1; the length of the outer row of precast piles 1 is longer than that of the inner row of precast piles 1; as the river slope of the river channel is in slope, the outer row of precast piles 1 is longer and connected with the vertical part of the inverted L-shaped breast wall 2, thus the structure is more stable and can better reinforce the existing revetment.
