Reveal the whole process of tunnel lining construction

Want to know how the tunnel "puts on a solid coat"? Reveal the whole process of tunnel lining construction and let you find out.

Check the section, pay-off positioning.

Before tunnel lining construction, it is necessary to check the section, setting-out and positioning of the tunnel to ensure the accuracy and accuracy of lining construction.

Prepare arched formwork and formwork.

In the tunnel lining construction, it is necessary to prepare tools such as arch formwork and vertical formwork to create a perfect "skeleton" for the tunnel and prepare for the subsequent lining construction.

Concrete preparation and transportation

In tunnel lining construction, the preparation and transportation of concrete are very important links. It is necessary to ensure that every drop of concrete is in place accurately and ensure the quality and efficiency of lining construction.

concrete pouring

In tunnel lining construction, concrete pouring is the key link. Through concrete pouring, the "coat" of the tunnel is gradually formed, which provides a solid guarantee for the use of the tunnel.

Maintenance and disassembly

After the tunnel lining construction is completed, it needs to be maintained and removed to ensure the quality and durability of the tunnel. Through maintenance and demolition, the tunnel has a new color and is more durable.
