Supporting structure for conveyer and construction method thereof

Abstract

The invention provides a supporting structure for a conveyer and a construction method of the supporting structure. The supporting structure for the conveyer comprises a supporting dam and conveyer supporting frames. The conveyer supporting frames are arranged on the two sides of the top face of the supporting dam in the length direction of the supporting dam. The supporting dam is of a laminatedstructure which is formed in the manner that multiple dam body base layers and multiple layers of keels are alternately constructed in a filling manner to become a whole. At least one layer of keels are arranged at the bottom of the supporting dam. The construction method comprises the steps that a construction site is leveled, filling construction is conducted with geotechnical fence nets used asthe keels and with ardealite used as the dam base material locally, and the conveyer supporting frames are installed on the top face of the supporting dam. By the adoption of the supporting structurefor the conveyer and the construction method of the supporting structure, the strength of the supporting structure is improved, installation and construction are convenient, resources are saved, thecost of the supporting structure is lowered, the supporting structure is suitable for keeping stable in severe environments and reduces the harm to the conveyer, and the equipment maintenance cost andthe potential safety hazards are reduced.

[0002] With the continuous development of the mining industry, the depth of mine mining continues to go deep into the ground. In various mining areas, various large-scale electromechanical equipment are widely used for operations. The application of these large-scale mining operation equipment not only reduces labor intensity, but also improves the efficiency of mining operations. , belt conveyor, also known as belt conveyor, is a commonly used mining conveying equipment, with high-speed, stable, low noise, and can be conveyed up and down slopes, etc., mainly used in conveying bulk materials, in the process of mining operations Among them, in order to increase the production output of enterprises, it is usually necessary to use belt conveyors to transport bulk minerals for a long distance. In this process, the geographical routes passed by the conveyors are very long, and various geological conditions are often encountered. And for some mineral resources with special physical and chemical properties, special care must be taken when transporting them. For example, phosphogypsum dihydrate. Take Guiyang Kailin Chemical Fertilizer Co., Ltd. as an example. The company currently widely uses wet-process phosphoric acid for production. The product is phosphogypsum dihydrate. At present, the belt test conveyor is mainly used for conveying operations. The phosphogypsum extracted and filtered contains 20%-25% of water. The phosphogypsum is transported to the unloading yard and stored naturally. For continuous production, the phosphogypsum unloading site continues to expand with production, and the conveying length of the belt conveyor continues to extend to the phosphogypsum accumulation body, but the material on the phosphogypsum accumulation body is generally soft, which is not enough to support the heavy belt conveyor For equipment, if the traditional steel structure is used to fix and support the conveyor, because phosphogypsum is dehydrating and corrosive, its pH value is about 2 to 3, and the phosphogypsum will sink and crack due to dehydration, and because the steel frame structure supports the bottom surface The contact area is small, and often after 2 months of use, the steel structure support will be deformed with the sinking of phosphogypsum. In severe cases, the weld will be cracked and the truss will be overturned, affecting the continuous operation of production, and sometimes even causing safety accidents , jeopardize the safety of operators and inspectors, and affect the service life of the belt conveyor, which increases equipment maintenance costs. If the steel structure truss is used to add sleeper support at the bottom of the steel structure truss, it still cannot change the sinking of the steel structure truss due to the dehydration of phosphogypsum. There is phosphogypsum ground, which causes the problem of deformation of the belt conveyor, and whenever the truss sinks severely, breaks or is in danger of overturning, the production has to be shut down, and the belt conveyor can only be operated after re-laying and installing , which affects the production efficiency, and the section steel dismantled from the steel structure truss can no longer be reused due to the corrosion of phosphogypsum, resulting in a huge waste of resources
