Problems solved by technology

Therefore, compared with the lifting and dismantling operations of towers with the same weight and the same geometric size without suction, lifting and dismantling towers with suction requires a larger crane, resulting in more crane costs and labor costs
[0004] Therefore there is above-mentioned inconvenience and problem in the tower body that there is suction in known hoisting and dismantling

Abstract

The invention provides a method for eliminating suction between a tower bottom plate and a foundation in tower replacement construction. The method is characterized by comprising the following steps that (a) a device for eliminating the suction between the tower bottom plate and the foundation is prefabricated; (b) the device for eliminating the suction between the tower bottom plate and the foundation is mounted on a tower foundation seat; (c) the device for eliminating the suction between the tower bottom plate and the foundation is connected with the tower foundation seat; (d) a jack is mounted; and (e) the jack is operated to form a gap in a jacking mode to eliminate the suction between the tower bottom plate and the foundation. The method for eliminating the suction between the tower bottom plate and the foundation in tower replacement construction has the advantages that the structure is simple, manufacturing is convenient, the suction between the bottom plate and foundation oil sand is thoroughly eliminated in the tower dismounting process, the tower dismounting time is effectively shortened, the specification of a crane is decreased, the crane rent cost is reduced, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a tower replacement construction method, in particular to a tower replacement construction method for eliminating suction between a tower bottom plate and a foundation. Background technique [0002] Towers are widely used in chemical production, and towers often need to be replaced after a period of use (or upgrade and replace towers with more advanced processes, or replace damaged towers). In the tower replacement, a crane is generally used to lift the tower away as a whole, but after the tower works for a certain period of time, there is a large suction force between the tower bottom plate and the base oil sand layer. There are two reasons for this suction: first, there is adhesion between the tower bottom plate and the base oil sand; second, the lack of air between the tower bottom plate and the base oil sand layer forms a vacuum, which causes the tower to bear downward. atmospheric pressure. [0003] figure 1 It is a sch...
