Description
Technical Field
[0001] The invention belongs to the technical field of unloading platform support of a mine crushing station, and in particular relates to an assembled retaining wall of a mobile crushing station. Background Art
[0002] At present, the primary crushing system of open-pit mines includes two forms: fixed crushing station and semi-mobile crushing station, and the semi-mobile crushing station is the main development trend. The semi-mobile crushing station is also called modular unit or sled unit. It is to place the machine body at a suitable working level in the open-pit mine. With the advancement and extension of the working steps, the crushing unit is moved as a whole (or in parts) by crawler transport vehicles or other traction (pulling) equipment. Semi-mobile crushing stations are usually arranged on the end wall of the mine, and the ore and rock transportation distance is less than 3km. When the mine steps extend beyond the reasonable transportation distance and climbing height of the car, the next relocation will be carried out.
[0003] In the design of semi-mobile crushing stations in open-pit mines, retaining walls are generally used to reduce the impact of the crushing station on the soil slope. Retaining walls refer to structures that support roadbed fill or hillside soil and prevent fill or soil from deforming and becoming unstable. In the prior art, concrete retaining walls or reinforced soil retaining walls are mostly used for construction, and then the slopes near the semi-mobile crushing stations in open-pit mines are poured to form concrete retaining walls to support the slopes. With respect to the above-mentioned related technologies, the inventor believes that when concrete retaining walls or reinforced soil retaining walls are used, the retaining walls will be abandoned when the crushing station needs to be moved, and the retaining walls have a long construction period, high cost, and cannot be reused, resulting in a lot of waste.
