[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be further described in detail below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model but not all. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 Embodiment 1, a protective wall structure for a fluidized solidified soil embankment, comprising a protective wall component 1 and a concrete foundation 2. The protective wall component 1 is provided with a left splicing groove 1-1 on the left side, an upper splicing groove 1-2 on the top, a right splicing protrusion 1-3 on the right side, a supporting side arm 1-4 on the inside, and a lower splicing protrusion 1-5 on the bottom.

[0021] The protective wall component 1 at the bottom of the protective wall structure is inserted into the concrete foundation 2 to form a whole, and the upper protective wall of the protective wall structure is spliced ​​by the protective wall components 1. The bottom splicing protrusion 1-5 of the protective wall component 1 can be inserted into the upper splicing groove 1-2 at the top of the protective wall component 1 below to perform upper and lower splicing. While the protective wall components 1 are spliced ​​up and down, the right splicing protrusion 1-3 of the protective wall component 1 can be inserted into the left splicing groove 1-1 of the adjacent protective wall component 1 to perform left and right splicing.

[0022] It should be noted that in this embodiment, the inner side of the protective wall component 1 is provided with supporting side arms 1-4, which can extend into the fluidized solidified soil and can be tightly combined with the solidified fluidized solidified soil. Compared with the flat protective wall, the supporting effect on the fluidized solidified soil roadbed is better.

[0023] In this embodiment, the protective wall component 1 is in an I-shape, has high rigidity, and is not easily deformed. The material may be a plastic steel plate or a concrete plate.

[0024] The lower part of the protective wall component 1 at the bottom of the protective wall structure is inserted into the concrete foundation 2 to ensure the stability of the overall structure.

[0025] The supporting side arms 1-4 are embedded in the fluidized solidified soil after the fluidized solidified soil is cured and solidified, thereby enhancing the overall stability of the fluidized solidified soil embankment.

[0026] After solidification, the fluidized solidified soil embankment forms a whole with the protective wall structure, and there is no need to cut slopes, thus reducing land occupation.

[0027] The utility model also provides a construction method for a protective wall structure of a fluidized solidified soil embankment, and the main steps of the construction method are as follows:

[0028] 1) Determine the required number of protective wall components 1 according to the roadbed design drawings.

[0029] 2) Measure and lay out, dig foundation pits in sections on both sides and in front and behind the designed roadbed position for pouring the concrete foundation 2 of the protective wall structure, vertically insert the protective wall component 1 at the bottom of the protective wall structure into the concrete foundation 2, and form a whole after the concrete foundation 2 hardens.

[0030] 3) According to the designed height of the embankment, pour the fluidized solidified soil in layers. After the fluidized solidified soil is initially solidified, the upper and lower and left and right splicing of the upper layer of protective wall components 1 is carried out. After the splicing is completed, pour the upper layer of fluidized solidified soil, and so on, until the pouring is completed.

[0031] 4) After the fluidized solidified soil embankment is poured and hardened, a hole can be opened at the bottom of the protective wall component 1 at the bottom of the protective wall structure to be used as a subsequent roadbed drainage hole.

[0032] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
