At about 14:00 on May 5, Humen Bridge vibrated significantly, and then it was fully closed in both directions

According to the latest expert analysis, water horses are the cause of vortex vibration, and the Humen Bridge is structurally safe

As soon as the bridge jittered, in order to ensure the safety of the bridge, the management and maintenance unit of the Humen Bridge has urgently begun a comprehensive inspection of the bridge.

In fact, it is not only when the bridge is shaking

On average, 174 million people pass on bridges with structural defects every day

There may be various defects and discontinuities in the weld

Welds and bolts connecting bridge steel supports are particularly susceptible to discontinuity, which can lead to corrosion and cracks

Professional testing personnel are naturally inseparable from professional testing equipment

Traditional non-destructive testing (NDT) methods

The traditional NDT method for detecting bridges is the Liquid Penetration Test (PT), which uses liquid dyes to detect cracks on the weld surface

Radiography is also a traditional NDT method for bridge inspection, but it is gradually abandoned by inspectors

Different categories of NDT methods

Industrial endoscope inspection point

• Support bearing: rubber deformation
• Floor back side: concrete cracks and peeling
• Floor drain: blocked
• Light poles and sign poles: anchor bolts and the roots of the poles

The service life of the bridge is generally about 50 years

What VANTA can accomplish are:

• 
  
  Check the grades of rebar materials
  .
  High-strength low-alloy steel used in earthquake-prone areas, high-chromium steel used in coastal areas corroded by sea salt/northern snow melting agent
  .
  
  


• 
  
  Study and detect the chlorine element penetrating into concrete bridges
  .
  Sea water, snow melting agent and road salt are easily absorbed by concrete materials, thereby corroding the steel materials in the concrete
  .
  
  


• 
  
  Detect the phosphorus content in the asphalt to determine the residual amount of added phosphoric acid
  .
  The difference in the content of sulfur and vanadium in the asphalt makes the type of asphalt different significantly
  .
  
  


• 
  
  Detect the content of arsenic and lead in the reflective glass beads added to the asphalt
  .
  Reflective glass beads added to asphalt can improve the reflectivity of the road surface, and reflective glass beads are mainly made of some recycled materials
