How to control the accuracy during the production and assembly process of building blocks

This is a major challenge faced by the project

To this end, the project drew inspiration from the prefabricated substructure

In municipal and plain area highways

After successful application experience

Conducted a second round**

During the production process

Strictly control key parameters

The error of each part of the prefabricated component finished product is within the range of 5 millimeters

During the assembly process

Installation using a pier beam integrated bridge erecting machine

Adjusting the jack and reaction frame

Can control installation accuracy within a range of 5 millimeters

In addition, there is an industry recognized difficulty

That is the quality control of the assembly nodes of "building blocks"

In prefabricated bridges

Higher requirements for node connection technology between "building blocks"

During this process, Guangxi Liyu 14 bid

An anchoring system using a combination of embedded steel bars, sleeves, and grouting materials

The joint surface is leveled with high-strength mortar and the sleeve is used after leveling

Control the deviation of pier column spacing within ± 2 millimeters

The Panlong Bridge not only meets the requirements of

The green concept of sustainable development

And the entire construction process is safe, * *, and controllable

To create quality engineering

For the four small brands of the company, "prefabricated buildings"

Provided successful cases
