A fixed column 2 is buried in the soil on the right side of the retaining wall 1. A deep pit can be drilled out of the soil using a drilling rig, and then the fixed column 2 is buried in it. The fixed column 2 is separated from the retaining wall 1 by a certain distance. A locking mechanism 5 is provided in the fixed column 2. A fixing nail 3 is fixedly connected in the retaining wall 1. The fixing nail 3 can be driven horizontally into the soil, and the other end of the fixing nail 3 is locked in the locking mechanism 5. Through the fixing of the fixed column 2 and the connection between the retaining wall 1 and the fixed column 2 by the fixing nail 3, the retaining wall 1 can withstand greater pressure and is not easy to collapse. Preferably, there are two fixing nails 3, one at the top and one at the bottom.

The fixing nail 3 is located on one side of the retaining wall 1 and extends out of the retaining wall 1. The left end of the fixing nail 3 is provided with a drainage outlet. When there is a lot of rain, there is a lot of water in the soil. When the original drainage mechanism of the retaining wall 1 is slow, some of the water will seep through the seepage hole 201, be filtered by the sand and gravel 4 and enter the drainage outlet 302. Finally, it will be discharged from the drainage outlet through the fixing nail 3, thereby reducing the drainage pressure and avoiding the collapse of the retaining wall 1 due to excessive water accumulation.
