Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0029] The express trestle bridge is composed of light and standardized truss unit components made of high-strength steel, beams, longitudinal girders, bridge decks, bridge seats and connectors, etc., and can be quickly assembled on site into truss beam bridges suitable for various spans and loads. Combined with the engineering characteristics of the electric power industry, after optimized design, it is applied to the high-altitude rapid layout of crawler cranes.

[0030] Such as figure 1 As shown, the construction method flow of trestle bridge based on high-altitude crawler crane is: crawler crane type selection → selection of trestle combination method → ​​bearing capacity check → trestle support seat arrangement → trestle assembly installation → walkway plate installa...

Abstract

The invention provides a construction method of a trestle based on a high-altitude crawler crane. The construction method mainly comprises the following steps: selecting the type of a crawler crane; selecting the combined manner of a crawler crane; checking bearing capability; arranging a trestle supporting seat; assembling and mounting a trestle; mounting a walkway plate; strengthening trusses; arranging a supporting seat of a crawler crane host machine; mounting the crawler crane; performing a load test; and putting the crawler crane into use. According to the construction method disclosed by the invention, through the creative arrangement of a high-altitude trestle for a crawler crane in the construction of the power industry, the bottleneck problem that no place can be used for machine arrangement is solved, and the hoisting capacity and the moving capability of a crane during the reconstruction realizing energy conservation and emission reduction are greatly improved. The trestle is rapid and convenient to mount, and the crawler crane can be rapidly put into use; the reconstruction period is greatly shortened; the reconstruction cost is reduced; the equivalent usable coefficients of used machine units are increased.

Description

technical field [0001] The invention belongs to the field of transformation and construction of thermal energy saving and emission reduction, and in particular relates to a construction method for the transformation and construction of a thermal power plant denitrification system based on the design of a high-altitude crawler crane trestle bridge. Background technique [0002] Since the promulgation of the National Environmental Protection "Twelfth Five-Year Plan", the power industry has optimized the power supply structure and promoted technological progress. The energy consumption and exhaust emissions of newly built units have reached the international leading level. In order to minimize the negative impact of the power industry on the environment and achieve a higher goal of energy conservation and emission reduction. Intensifying energy-saving and emission-reduction reforms for thermal power units in service is an urgent and important measure to reduce pollutant emissio...
