[0058] In summary, the utility model realizes the initial protection of the bank of the river channel by setting the prefabricated upright pile wall embankment protection structure 1 on the side of the river channel, and then sets the cast-in-place pile structure 2 on the earthwork on one side of the river channel, and hoists the prefabricated interlaced composite beam 3 on the earthwork on one side of the river channel, so that the prefabricated interlaced composite beam 3 and the first exposed steel bars 121 of the prefabricated upright pile wall embankment protection structure 1 and the second exposed steel bars 21 of the cast-in-place pile structure 2 have an initial position connection relationship, and then arranges the prefabricated retaining wall 5 on the composite roadbed 4, and sets the concrete structure 6 on the prefabricated upright pile wall embankment protection structure 1 and the cast-in-place pile structure 2. The concrete structure 6 is cast above the prefabricated alternating composite beam 3 and the prefabricated vertical pile wall embankment protection structure 1, the cast-in-place pile structure 2, the prefabricated alternating composite beam 3, the composite roadbed 4, and the prefabricated retaining wall 5, so that the concrete structure 6 connects the prefabricated vertical pile wall embankment protection structure 1, the cast-in-place pile structure 2, the prefabricated alternating composite beam 3, the composite roadbed 4, and the prefabricated retaining wall 5 together, thereby quickly forming an assembled integral embankment engineering structure 100 for water retaining protection of the river channel, so as to realize the transformation of the implementation mode of embankment structure construction from traditional cast-in-place to assembled construction, avoiding the problems of poor molding quality and collapsed holes caused by the traditional use of only cast-in-place pile construction and only on-site casting of the integral embankment engineering structure, and ensuring the quality reliability of the embankment engineering. Secondly, assembled construction can complete the assembly of flood control roadbed, retaining wall and face protection of the embankment engineering in a short time, and the technical characteristics of prefabricated construction without formwork can immediately enter the composite casting construction link, greatly shortening the overall construction period of the embankment engineering, and has the characteristics of short construction period in the flood control field that is affected by the complex surrounding environment and flood season and races against time to rush for construction period. Thirdly, the prefabricated upright pile wall embankment protection structure 1, prefabricated interlaced composite beams 3, composite roadbed 4, prefabricated retaining wall 5 and other components of the utility model can be standardized and modularized. Through standardized design, different prefabricated components can be universally used, reducing design and manufacturing costs, which is conducive to reducing component weight, special-shaped contour demoulding and achieving clear concrete surface, making production, transportation and installation more efficient. In addition, the utility model is suitable for complex basin construction environments and is not affected by the construction needs of complex basin construction environments such as no beach outside the embankment, restrictions on existing buildings, and poor foundation soil. Furthermore, the utility model can reduce the construction intensity. The embankment project is constructed in strips along both sides of the river, and the project volume is large. The prefabrication and assembly of the structural components of the embankment project can realize direct installation on the construction site, reducing the construction intensity of steel bar binding and concrete pouring on the traditional embankment project site. In addition, the bored piles, flood control walls and flood control roads can be well streamlined for construction, and the construction and installation are mainly construction hoisting. The construction process reduces the deployment of on-site personnel, reduces the input and dependence of labor, saves labor costs and is conducive to safe production. The construction site reduces construction waste, saves energy, is environmentally friendly and easy to maintain, and is particularly suitable for projects with high requirements for on-site safe and civilized construction.
