Problems solved by technology

[0005] 1) During the hoisting process, in order to improve the hoisting efficiency, it often requires the cooperation of multiple people, and whether it is before or after the hoisting, it is necessary to manually hook the hook to the prefabricated basic component or hook the hook Removing it from it requires a large amount of manual work, and it is not convenient to remove the hook from the assembled basic component
[0006] 2) When the traditional simple spreader is used for hoisting, it is necessary to manually adjust the lifting balance, and the stability of the traditional spreader is not good, especially when working in windy weather, the spreader will shake obviously due to poor stability. In turn, the reliability of hoisting is increased by unstable factors, and there are greater construction safety hazards when hoisting at high altitudes

Embodiment Construction

[0042] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and To facilitate its practice, but not as a limitation of the invention.

[0043] Such as figure 1 As shown, a construction method of an outdoor substation, the construction method specifically includes the following steps:

[0044] S1. Clean up weeds and rubbish on the ground to be constructed, and initially level the ground, and then locate the defense line according to the requirements of the construction drawing; excavate the earthwork at the position of the foundation pit on the ground determined after positioning and laying out the line, until the design is reached To the depth position, and clean the bottom and trim the founda...

Abstract

The invention relates to an outdoor transformer substation building construction method, in particular to a special lifting appliance for a GIS assembly type foundation componen. The lifting appliance comprises a suspension frame, a suspension arm group mechanism, a side support rod assembly and a lifting hook mechanism. According to the outdoor transformer substation building construction method, when assembly construction of a GIS assembly type foundation is carried out, in the hoisting process of prefabricated parts through the special lifting appliance, compared with a traditional simple lifting appliance, the human input is reduced, the inconvenience of manual operation is solved, automatic hooking and hook unloading can be realized, and high-efficiency lifting operation is facilitated; in addition, the structure of the whole lifting appliance is more stable and reliable, the lifting appliance is not easily influenced by severe outdoor weather such as strong wind, the balance is better, the use reliability of the lifting appliance during lifting is enhanced, and the potential safety hazard during high-altitude lifting operation is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of substation construction and specifically proposes an outdoor substation construction method. Background technique [0002] In the construction and assembly of substations, GIS is an important switchgear in the main control room. The full name of GIS is gas-insulated metal-enclosed switchgear. The optimized design is organically joined into a whole, and it is sealed in a metal shell, filled with SF6 gas as a closed combination of arc extinguishing and insulating medium. [0003] The GIS equipment foundation is the installation foundation for carrying and placing GIS equipment. The commonly used foundation forms of GIS equipment foundation include thick slab foundation, beam raft foundation, buttress raft foundation, box foundation, etc. None of these foundation forms can get rid of the problems that the GIS foundation has a large volume, a long construction period, and cracks are not easy to control. Th...
