Mobile assembly type steel structure bridge culvert

Abstract

The invention relates to a mobile assembly type steel structure bridge culvert. The bridge culvert comprises a main bridge, an approach bridge I, an approach bridge II, a supporting assembly I and a supporting assembly II, the first supporting assembly and the second supporting assembly are used for supporting the first approach bridge and the second approach bridge respectively. The main bridge is located between the first approach bridge and the second approach bridge, and the two ends of the main bridge are supported by the first supporting assembly and the second supporting assembly respectively. The first approach bridge, the main bridge and the second approach bridge are sequentially in butt joint to form a continuous bridge floor. The invention has the positive effects that the same-level or approximately same-level transportation of the cross-belt conveyor on the dump truck is realized, the invalid transportation distance of the truck is reduced, the transportation efficiency of an open-pit mine truck system is improved, and the investment of transportation equipment is reduced; the bridge and culvert moving cost and the bridge and culvert construction cost are reduced, thebridge and culvert moving construction period is shortened, the effective production operation time of the strip mine is prolonged, and efficient production of the strip mine is guaranteed.

Description

technical field [0001] The invention relates to a process equipment for solving the cross influence of the open-pit mine transportation system, which is applied to the straddle-belt conveyor for truck transportation in the open-pit mine, in particular to a removable assembled steel structure bridge and culvert. Background technique [0002] Large-scale open-pit mines in my country usually adopt a combination of multiple processes to form a comprehensive production and transportation system in which truck transportation and continuous and semi-continuous processes using belt conveyors coexist. However, in the actual mining process, due to the influence of the layout of the belt conveyor, there is often an intersection phenomenon between the truck transportation and the belt conveyor system. Conveyor trenches intersect with truck roads. The specific cross-effects are manifested as: arranging belt conveyor trenches or plane roads at the end of the open-pit mine or other locati...

AI Technical Summary

Problems solved by technology

However, with the impact of the regular relocation of the belt conveyor, the culvert is faced with multiple demolition and reconstruction processes, which not only increases the construction period, but also increases the construction investment because the culvert cannot be reused as a whole; Under the condition of truck transportation as the mainstay, in the open-pit mine stope at the end side or other appropriate positions, by erecting the belt conveyor trestle, realize the three-dimensional non-crossing transportation system of the truck transportation under the trestle and the belt conveyor transportation on the upper part

However, due to the large tonnage of trucks in large open-pit mines, generally 100-220 tons, the height of the truck itself is generally 5-8m. At the same time, considering a certain safety clearance height, the height of the trestle bridge where the trucks pass is above 6.5-9.5m. As a result, the structure of the trestle bridge is complex, the cost is high, and it is more difficult to relocate in the later stage. At the same time, uncertain safety hazards are added
