Advanced tank jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking advanced tank jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters advanced tank jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

l Environmental protection measures
The installation of pipeline construction equipment is one of the necessary steps in the industrial field, and the installation and construction of pipeline construction equipment is a very important stage in project construction.
Due to the influence of various factors during project construction, there are many problems in the installation of pipeline construction equipment. In order to promote the improvement of industrial pipeline installation quality, certain measures need to be taken to control the pipeline installation quality to ensure the smooth completion of project construction.
① The construction site should be kept clean. All items should be arranged in time and placed in an orderly manner.
② Noise should be controlled during operation, and operation time should be arranged reasonably to reduce the impact on the surrounding environment.
③ The working lights at night should be irradiated into the field, and protective measures should be taken for the welding arc.
④ The oil used in operation machinery shall not be dumped at will to prevent pollution.
⑤ Waste materials, steel materials, welding heads, welding wire heads, etc. left over during operation should be collected separately, treated or recycled in a unified manner.
Introduce the influencing factors in the installation of pipeline construction equipment.
l Bracket installation quality
In the installation of pipeline construction equipment, the installation of the bracket is relatively important, which plays a very good role in the quality of pipeline installation and the normal operation of the equipment. Among them, the installation of the bracket has a certain impact on the overall performance of the pipeline.
For example, the carrying capacity of the scaffold must meet the standard, the sliding surface of the support and the supporting surface have good connection performance, etc. Therefore, the pipeline construction process needs to be carried out according to the engineering construction drawings and pipeline construction equipment installation and construction process specifications to avoid installation Quality has a certain impact.
l Welding quality
Welding in the installation of pipeline construction equipment is also one of the necessary links. The quality of welding affects the overall quality of pipeline installation. Pipe welding can ensure the performance of the undertaking project frame group, thereby ensuring the overall performance of the pipeline. Therefore, precise welding is required in welding, positioning welding position to ensure welding quality, and welding in strict compliance with welding procedures and specifications.
In welding, especially the position of the welding seam, the welding process requirements of the welding workers are very high. The relevant personnel are required to do a good job in welding quality control in this link, and to formulate specific solutions for possible situations to avoid The overall performance of pipeline construction equipment has a certain impact.
l Pipeline anticorrosion
The particularity of the use environment of pipeline construction equipment and the particularity of the use location require the pipeline to have certain anti-corrosion performance. In the pipeline anti-corrosion, the anti-corrosion material will choose paint, and the economical and reasonable pipeline paint can be selected for pipeline anti-corrosion in the process of use.
To reduce the risk of pipeline construction equipment being corroded, paint itself is a corrosion-resistant substance, which is an industrial raw material and anti-rust material for construction. Applying a layer of paint on the surface of the pipeline can extend the service life of the pipeline.
