Mounting method of deep well high pressure aeration reactor steel drum

Abstract

The invention discloses an installation method for a steel cylinder of a high-pressure aeration reactor of a deep well, comprising the following steps of: processing and manufacturing an inner baffle; determining the installation position of the inner baffle: the steel cylinder consists of a plurality of groups of steel cylinder sections from bottom to top, the inner baffle is arranged on the steel cylinder section with the number of M and the length ratio of the upper part and the lower part of the inner baffle is 2.5 to 4.0 : 6.0 to 7.5; installing a plurality of groups of steel cylinder sections of the lower part of the inner baffle in sequence from bottom to top; installing the inner baffle; sinking and temporarily fixing the steel cylinder section with the number of M+1; sinking and installing the steel cylinder section with the number of M+2 after the pressure in the cylinder is transmitted up uniformly and installing a plurality of groups of steel cylinder sections of the upper part in sequence according to the installation method thereof; pouring concrete or mortar to the outside of the steel cylinder; releasing the pressure and carrying out cutting recovery of the inner baffle. The invention can solve the lifting problem of the steel cylinder and the instability and distortion problem of the steel cylinder under the effect of the side pressure of the slurry outside of the cylinder, can ensure that the steel cylinder sinks to the designed elevation safely and smoothly and can save the construction cost.

Description

technical field [0001] The invention relates to the technical field of deep well operation and construction, in particular to a method for installing a steel drum of a deep well high-pressure aeration reactor. Background technique [0002] At present, for the deep well high-pressure aeration reactor developed and produced in Canada, the diameter of the reactor steel drum is 3200mm, the wall thickness is 20mm, and the depth is 92m. It is large in size and heavy in weight. The construction is very difficult and difficult to operate. Due to the large depth of the steel barrel of the reactor, in the actual installation process, the steel barrel is generally divided into multiple groups from bottom to top for group installation, and most of them are divided into thirteen groups. [0003] The installation method provided by the Canadian manufacturer is the suspension method and the water-sinking method, that is, the steel drum is installed by using the suspension method to fill a...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an installation method for the steel drum of a deep well high-pressure aeration reactor, which can effectively solve the problem of instability and deformation of the steel drum under the lateral pressure of the mud outside the drum. And the hoisting of the steel drum can ensure that the steel drum can be safely and smoothly sunk to the design level and can save construction costs
