The stacker-reclaimer is a novel efficient continuous loading and unloading device in a mechanized raw material yard. The running mechanism of the stacker-reclaimer runs along two parallel steel rails fixed on the ground. The stacker-reclaimer has higher requirements on the deformation, the straightness and the like of the track in the operation process. In order to meet the deformation requirement of the track, rigid foundation or flexible foundation is usually arranged for the track in engineering. The rigid foundation is a continuous long concrete foundation, the section of the rigid foundation is generally large, the rigid foundation has high rigidity and small deformation, but the manufacturing cost is high, especially in soft soil areas. The flexible foundation is composed of a standard railway ballast and a sleeper, has a large adjustment degree, and can adjust the sleeper according to the deformation condition of a track so as to achieve the purpose of eliminating deformation.

However, most of the current raw material yards in the industries of steel, electricity and the like are close to the wharfs of river and sea ports. Soil layers at the bottom of the raw material yard are mostly soft soil such as silt, soft plastic clay, loose sand and soil, the bearing capacity of the soil layers is low, and the sedimentation is large under the stacking effect. Under the condition, if a rigid foundation is adopted, pile foundations are required to be adopted, the quantity of piles is large, the construction cost is high, and under the pressure close to a material pile, the foundation can generate large irreversible horizontal deformation, so that the deformation requirement of the track is difficult to meet.
