Abstract

The invention discloses a coal bunker construction technology. The technology comprises the steps as follows: the center point of a coal bunker is determined and a raise-boring machine is mounted; 2)the raise-boring machine drills a guide hole at the center point of the coal bunker, and the guide hole is reamed; 3) after a blank hole is formed after reaming, the raise-boring machine is dismounted, and a drawing hoist is mounted; 4) an arm protecting sleeve is mounted; 5) after the perpendicularity of the arm protecting sleeve is adjusted, an annular gap is filled with concrete; 6) performingbrushing expansion and wall supporting on a loading chamber of a lower port of the coal bunker, the side of the loading chamber adopts I-shaped steel as a gable to support a coal feeder platform, concrete is poured, then, a whole coal bunker funnel wall is poured from bottom to top. The technology has the advantages that one-time reaming forming can be realized with the construction technology, the labor intensity of workers is reduced, the construction efficiency is improved, operators are not required to go deep into the coal bunker for construction, the safety coefficient is high, meanwhile, the process is simplified, assembly is convenient and simple, labor force and time are greatly saved, and the construction cost is saved.

Description

technical field [0001] The invention relates to the technical field of coal mine construction, in particular to a coal bunker construction technology. Background technique [0002] Large-scale coal preparation plants in my country's coal industry generally have to build large coal bunkers such as raw coal bins, gangue bins, and mixed coal bunkers. In the past, the coal bunker construction process: the ordinary smooth blasting method was used for construction, and the charges were charged in stages. The construction method of blasting and "one tunneling, one anchor, mesh spraying support" is used. After the construction section reaches a height of 1.5m, the metal skeleton is erected and the wooden formwork or steel formwork is used for concrete pouring. After 24 hours of solidification, the next cycle of construction will be carried out. The existing announcement number CN106223978B discloses "Construction Technology of Integral Downward Metal Formwork Construction Coal Bunker...
