Embodiment Construction

[0018] The present invention relates to a method for on-line overall replacement of equipment foundations, which includes: an off-line prefabrication step for new equipment foundations before the shutdown of the production line, a removal step of the original concrete foundation after the shutdown of the production line, and subsequent lifting of the removed concrete foundation The departure steps and the online assembly steps of the new equipment foundation that has been prefabricated off-line are hoisted in place by double-machine hoisting, see figure 1 .

[0019] In the online overall replacement method of the equipment foundation, the original concrete removal step includes removing the original concrete foundation by using a row of hole cutting method, a diamond chain cutting method, a butterfly cutting method, a static crushing method or a cracking method.

[0020] The method for on-line overall replacement of the equipment foundation, the method for cutting ...

Abstract

The invention relates to upgrading of equipment in industrial and mining enterprises, in particular to a renovation construction method of a replaced equipment foundation. An on-line overall replacement method of an equipment foundation comprises a step of carrying out off-line prefabrication on a new equipment foundation before stopping of a production line, a step of dismantling an original concrete foundation after stopping of the production line, a step of hoisting the dismantled concrete foundation to leave the field and a step of carrying out on-line assembly on the new equipment foundation which completes off-line prefabrication. According to the on-line overall replacement method, the construction period is greatly shortened, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to equipment renovation in industrial and mining enterprises, in particular to a renovation construction method for replaced equipment foundations. Background technique [0002] In the past ten years, due to the economic development of our country, a large number of reconstruction and reconstruction projects have been caused to meet the growing demand. The original production facilities, etc., must be more or less involved in the demolition of the structure during the transformation. Using traditional concrete demolition equipment such as pneumatic picks and pick machines, the transformation may cause problems such as tight space, more construction waste, dust, noise, and high labor intensity. The efficiency is low, and it will affect other equipment, production and construction. Vulnerable to damage to preserve the integrity of part of the structure. [0003] The most important thing is that the transformation takes a long time...
