5 types of smart construction

▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄

Ready-mixed fluid solidified soil backfill process

Can flow into deep and narrow fertilizer trough by itself

High strength after molding and curing

Avoid dust easily generated by traditional earthwork backfilling

Poor backfill quality problem

Automatic welding technology

Can greatly improve the flatness and stitching quality of welding

Effectively guarantee the quality and beauty of construction

BIM modeling and 3D printing technology

In line with the concept of green development

Able to perform entity analysis and application on complex nodes

thereby improving the accuracy of the construction process

Greatly improve work efficiency and save material consumption

Glodon Intelligent Material Acceptance System

Can automatically collect real-time accurate data

Leverage cloud computing technology

Effectively accumulate and integrate all data

and conduct comprehensive control over the entry and exit of materials.

Cloud tunnel safety management and control system

Adopt 5-layer architecture solution

Can effectively manage the access of personnel in underground pipe corridors

and device positioning

Real-time call data communication is also possible

and provide emergency protection

In this way, the operation in the limited space of the pipe gallery can be achieved from a macro perspective.

conduct behavioral control

Achieve environmental information monitoring and safety warning
