The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
Due to the limitations of engineering technical conditions and the like, particularly relates to the field of gravity type retaining wall semi-prefabrication technology, is in a horizontal plate assembly type structure at present, mainly adopts cast-in-situ construction, but the construction method is difficult to meet the construction requirement under the conditions that the construction period is particularly urgent and traffic cannot be closed for a long time. In addition, the whole size of the existing prefabricated retaining wall baffle is oversized, the wall body reaches the design elevation once, and inconvenience is brought to transportation and installation.
In order to solve the above problems, as shown in fig. 1, 2, 3 and 4, a semi-assembled arch retaining wall according to an embodiment of the present utility model includes: the cast-in-situ reinforced concrete retaining wall comprises a cast-in-situ reinforced concrete base 1, a cast-in-situ reinforced concrete first buttress wall 2, a cast-in-situ reinforced concrete second buttress wall 3 and a precast reinforced concrete arch retaining wall 4.

That is, the prefabricated reinforced concrete arch retaining wall 4 is simultaneously connected with the cast-in-situ reinforced concrete first buttress wall 2, the cast-in-situ reinforced concrete second buttress wall 3, and the installation surface 11.
Wherein, cast-in-situ reinforced concrete first buttress wall 2 and cast-in-situ reinforced concrete second buttress wall 3 are arranged at intervals along the length direction of installation face 11.

It can be understood that when the number of the cast-in-situ reinforced concrete first buttress wall 2 and the cast-in-situ reinforced concrete second buttress wall 3 is plural, the plurality of cast-in-situ reinforced concrete first buttress walls 2 and the plurality of cast-in-situ reinforced concrete second buttress walls 3 are arranged in parallel, and the arrangement directions are consistent, so that the load born by the semi-assembled arch retaining wall can be uniformly dispersed, and the structure of the semi-assembled arch retaining wall is firmer.
In an alternative embodiment, as shown in fig. 1, a plurality of prefabricated reinforced concrete arch-shaped retaining walls 4 are provided, and the plurality of prefabricated reinforced concrete arch-shaped retaining walls 4 are sequentially stacked in a direction away from the installation surface 11.

The length of the protrusion 42 may be equal to or slightly smaller than the length of the bottom side of the precast reinforced concrete arch retaining wall 4. In the case where there are three protrusions 42, there are three grooves 41. The three protrusions 42 are respectively arranged at two ends and the center of the bottom side of the precast reinforced concrete arch retaining wall 4, and the grooves 41 are arranged in one-to-one correspondence with the protrusions 42.
