Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; but not all embodiments, are based on the embodiments of the invention; all other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of protection of the present invention.

Referring to fig. 1 to 2, a vertical riverway embankment structure includes a plurality of segment structures, each of which includes a bottom plate 1 and a soil-blocking plate 2 perpendicular to the bottom plate 1; the bottom plate 1 and the soil blocking plate 2 are made of reinforced concrete, the bottom plate 1 is laid at the bottom of a river bed, reinforcing steel bars of the soil blocking plate 2 are bound with reinforcing steel bars of the bottom plate 1 and then are integrally cast, the poured bottom plate 1 provides transverse supporting force for the soil blocking plate 2, soil on the backwater side of the river bank is prevented from collapsing into a river channel, and a safe and stable river bank line is provided for the river channel; meanwhile, after the soil retaining plate 2 is supported by the bottom plate 1 in a sufficient and stable manner, the integral casting process reduces the utilization of the space of the matrix at the lower part of the bottom plate 1, thereby reducing the influence on the existing laid pipeline 5.

For river course water passing area between the both sides retaining plate 2, this vertical type river course embankment structure is formed by connecting a plurality of segmentations, when making things convenient for the building, is provided with expansion joint 6 structures between each segmentation, expansion joint 6 structures are for preventing the too big additional internal stress of structure that temperature variation and concrete contraction arouse to avoid arousing the structure when the internal stress that is pulled surpasss the tensile strength of concrete and produce the crack.

The bottom plate 1 and the retaining plate 2 are respectively and uniformly provided with a water drain pipe 3; the water drain pipe 3 is generally a hard pipeline such as a PVC pipe or a steel pipe, and the water drain pipe 3 is a pipeline which is far away from one side of the river channel water passing area and is inclined downwards and close to one side of the river channel water passing area; through the uniformly arranged plurality of water drain pipes 3, water on one side of the retaining plate, which is far away from the water passing area of the riverway, can be smoothly discharged, the water level of underground water on the back of the retaining plate is reduced, and the water pressure on the back of the retaining plate is reduced, namely the possibility that the retaining plate is unstable or overturned due to pressure is reduced; the geotechnical cloth inverted filter layer can avoid impurities such as soil from entering the water drain pipe 3, and then blocks the water drain hole to cause water to flow out smoothly.

As an optional implementation mode, a geotextile reverse filter layer 4 is arranged at the end of one side of the water drain pipe 3, which is far away from the water passing area of the river channel; the earthwork cloth for engineering has the characteristics of high strength, good water permeability, corrosion resistance and the like, is made of lighter materials, and is more convenient in transportation and laying work; the filter is arranged at one end of the water drain pipe 3 buried in soil, and is usually buried underground, so that the requirement on the antimicrobial property of the material is higher, and the geotextile simultaneously meets the performance requirements, so that the filter is suitable for the work of filtering and preventing impurities at the end of the water drain pipe 3 in the embankment structure from entering the pipe.

As an optional implementation manner, a caulking layer is arranged in the expansion joint 6, and asphalt numb thread caulking is filled in the caulking layer; the filler in the expansion joint 6 is used for ensuring that foreign matters enter the expansion joint 6 to influence the performance of the expansion joint 6, so that the overall structural performance of the river embankment is influenced; the embankment structure adopts the asphalt numb threads for caulking, and the asphalt numb threads have better elasticity and waterproofness, so that the embankment structure can be better applied to nearby water structures, and has the advantages of simplicity and convenience in the actual construction process; therefore, the asphalt numb threads are utilized for caulking, the embankment structure can be better prevented from being damaged by internal tensile stress when deformed due to the change of environmental temperature, and meanwhile, the water flow of the tissue can well enter the member through the contraction joint to wash the foundation layer, so that the phenomena of cracks, collapse and the like are caused.
