[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 — Figure 4The utility model discloses a prefabricated assembled concrete retaining wall, including prefabricated concrete piles, prefabricated concrete tension beams and prefabricated concrete baffles. Furthermore, the prefabricated concrete piles include two parts: an above-ground prefabricated concrete pile and an underground prefabricated concrete pile. Preferably, the above-ground prefabricated concrete piles are hollow prefabricated concrete piles, and the lower half of the underground prefabricated concrete piles are conical. During the specific construction, the underground prefabricated concrete piles can be nailed into the ground. Furthermore, a straight threaded sleeve 1 is pre-embedded on the underground prefabricated concrete piles, and the straight threaded sleeve 1 is pre-embedded at the uppermost end of the underground prefabricated concrete piles. A semi-grouting sleeve 2 is pre-embedded in the above-ground prefabricated concrete piles, and a grouting hole 3 and a grouting hole 4 are reserved at corresponding positions in the above-ground prefabricated concrete piles. Furthermore, a straight threaded steel bar 5 is inserted into the straight threaded sleeve 1, and the above-ground prefabricated concrete piles and the underground prefabricated concrete piles are connected by the straight threaded steel bar 5, and the straight threaded steel bar 5 plays the role of positioning and reinforcing bars.

[0019] Furthermore, a concrete baffle interface 6 and a concrete tie beam interface 8 are reserved on the side of the ground precast concrete pile. Preferably, the concrete baffle interface 6 and the concrete tie beam interface 8 are both reserved in advance, and the precast concrete tie beam is connected to the precast concrete piles at both ends through the concrete tie beam interface 8.

[0020] The precast concrete piles are arranged regularly according to the size of the precast concrete baffles, and the concrete baffle interface 6 and the precast concrete tension beam are correspondingly arranged at the corresponding position of each precast concrete pile.

[0021] Furthermore, a slot 7 is reserved on the precast concrete tie beam. Preferably, the slot 7 is reserved on both the upper and lower surfaces of the precast concrete tie beam to facilitate upper and lower splicing. The precast concrete baffle is connected to the precast concrete piles at both ends through the concrete baffle interface 6 and the slot 7. The upper and lower ends of the precast concrete baffle are clamped on the slot 7 on the precast concrete tie beam.

[0022] Furthermore, the heights of the driving positions of all precast concrete piles should be kept consistent, and after installation, the semi-grouting sleeve 2 and the precast concrete piles on the ground are filled, preferably, with concrete mortar.

[0023] In this embodiment, the concrete retaining wall is mainly assembled and installed by means of the concrete retaining plate interface 6, the concrete tension beam interface 8 and the slot 7, and is grout-connected and fixed at the same time. Optionally, the precast concrete piles, precast concrete tension beams and precast concrete retaining plates can be adjusted in size according to actual application conditions.

[0024] During the specific construction, first, after the underground precast concrete piles are nailed into the ground, the straight threaded steel bars 5 are inserted into the straight threaded casing 1, and the above-ground precast concrete piles and the underground precast concrete piles are spliced. After the splicing and installation are completed, the precast concrete baffles are installed on the concrete baffle interfaces 6 on both sides, and the precast concrete tie beams are spliced ​​and installed on the concrete tie beam interfaces 8 on both sides. The slots 7 on the precast concrete tie beams clamp the precast concrete baffles. After the splicing and installation are completed, grouting is performed through the grouting holes 3 reserved on the precast concrete piles until grouting occurs through the grouting holes 4. Mortar is used to seal the grouting holes 3 and the grouting holes 4, and grouting is performed into the hollow precast concrete piles at the same time until they are full.

[0025] It is worth noting that before grouting the hollow precast concrete pile, a mortar fluidity test needs to be carried out, and grouting and compaction need to be carried out simultaneously. At the same time, anti-rust measures need to be taken for the straight threaded casing 1.
