Description

A kind of installation method of gas cabinet

technical field

The invention relates to a method for installing a large dry-type gas tank.

Background technique

Dry-type gas holder is a kind of gas holder. This construction device is used in many construction sites. According to different construction requirements, the specifications and sizes of dry-type gas holders are also different. The common installation method of dry-type gas tank is to use crane or tower crane to complete the installation directly. However, this conventional installation method is only suitable for gas tanks with small capacity and low height. For large dry-type gas tanks, especially the height of For dry-type gas tanks over 50m in height, it is difficult to complete the installation task by commonly used cranes or tower cranes due to insufficient height. More importantly, the use of cranes or tower cranes will be limited by the construction site. If tower cranes cannot be installed on the construction site, or cranes cannot be used for construction, then the installation of gas tanks cannot be implemented, and the construction cost of using cranes or tower cranes is very high. , the average daily construction cost can even reach more than 20,000 yuan, and the installation of a large dry-type gas tank often takes a month or even longer, so the total cost of using tower cranes or cranes for construction may be as high as hundreds of thousands, which greatly exceeds the budget , which increases the cost of the construction party, so adopting a new installation method or adopting a new process is an inevitable choice for dry gas cabinet installation.
