Problems solved by technology

[0003] The first purpose of the present invention is to provide a method for rectifying the deflection of the low-position high-voltage charged frame / support foundation in order to overcome the disadvantage that the existing conventional equipment cannot sink the foundation of the low-voltage high-voltage live frame / support under live conditions. This correction method can ensure the effective correction and reset of high-voltage live frame / support sinking, and meet the requirements of safe operation of equipment

Abstract

The related process method for low-position high-pressure charged frame / bracket foundation declined sinkage comprises: 1. cleaning the field for the requested work surface of correction device and the holding platform; 2. adjusting the jack of the correction device to deviate from the axis of pressed peg; 3. on the holding platform of correction device, stacking as the single-peg request; 4. inserting the short peg with length less than 2m from the pre-set cavity of door-type steel frame; and 5. lifting the platform by the hydraulic jack and back-pressed shift, transferring the back-pressure to the top of short peg to make the fundament peg sink. This invention has well reliability, and introduces no noise or pollution.

Description

Technical field [0001] The invention relates to a method for correcting deviation of a low-position and high-voltage live frame / support foundation and a special correcting device thereof. It belongs to the technical field of power station frame / support foundation construction. Background technique [0002] At present, many substations are built on deep silt sites, and it is easy to cause large-area settlement of the foundation of the structure after a period of operation. Due to the large-area sinking of the foundation of the frame, it will cause distortion and deformation of the frame beams of the entire power station. This will seriously threaten the safety of the operation of power equipment on the one hand, and on the other hand will seriously affect the power supply reportability of the hub station. Since this type of substation is built on a deep silt site, the equipment of the substation is low, therefore, when the equipment is energized, the conventional equipment of the...
