Furthermore, the cement wall is of a trapezoid structure, and the size of the cement wall is gradually increased from top to bottom, so that the whole wall can conveniently cope with the extrusion force of surrounding soil.

Furthermore, the pouring direction of each layer of cement blocks is from left to right, from right to left, from the middle to two sides or from two sides to the middle, so that the next cement block pouring can be performed after the cement blocks complete shrinkage deformation.

Furthermore, a plurality of shrinkage holes are formed in the middle of the cement block, so that the stress release of the cement block can be further facilitated.

The utility model has the technical effects and advantages that:

1. in the construction process, the wall body is divided into a plurality of cement blocks for pouring, and after the previous cement block is dried and shrinkage deformation is completely completed, the next cement block is poured, so that the stress is basically released completely in the construction process, and the crack of the wall body is avoided, thereby effectively ensuring the stability of the whole wall body.

2. According to the utility model, when the next cement block is poured, waterproof paint can be brushed or a waterproof rubber cushion can be stuck on the side surface of the existing cement block which has completed shrinkage deformation, so that a buffer belt can be formed between two cement blocks, and the release of stress in the cement blocks is further facilitated.
