Galvanized corrugated culvert pipe introduction and advantages

Galvanized corrugated culvert pipe refers to the corrugated steel pipe laid in the culvert under the road, railway, it is made of Q235 carbon steel plate rolled or made of semicircular corrugated steel sheet circular bellows, is a new technology. Its performance stability, convenient installation, favorable environmental protection, low cost advantages quickly replace the traditional reinforced concrete in highway construction, development prospects are very broad, mainly used in roads, Bridges, channels, retaining walls and various mines, roadway retaining wall support, reinforcement of old Bridges and culverts, tunnels, subgrade drainage ditch, escape hatch and many other projects.

Basic requirements for quality inspection of galvanized corrugated culvert pipe

(1) Galvanized corrugated culvert pipe monomer must be accompanied by product quality certificate when leaving the factory, no qualified certificate shall not leave the factory.

(2) Galvanized corrugated culvert pipe must be inspected piece by piece after it is transported to the construction site. No deformed steel plate shall be used during transportation.

(3) The bearing capacity of the foundation must meet the calculation requirements. Overdigging, backfilling and elevation control are strictly prohibited.

(4) galvanized corrugated culvert pipe, in order to ensure that the joint lap tight, must clean the joint.

(5) The installation and laying of galvanized corrugated culvert pipe should be smooth, the slope of the bottom of the pipe should not be reversed, and there should be no soil, masonry and other debris in the culvert.

(6) Effective measures must be taken to ensure the quality of galvanized corrugated culvert pipe backfill soil.

(7) After the high-strength bolt is tightened, the joint should be coated with sealed waterproof material (or hot asphalt), and then the secondary anti-corrosion.

Compared with reinforced concrete culvert, galvanized corrugated culvert has the following advantages:

1, galvanized corrugated culvert pipe is easy to maintain, just do a good job of the inner wall protection.

2. Galvanized corrugated culvert pipe has obvious economic benefits in alpine frozen soil area and soft soil road base zone.

3, galvanized corrugated culvert pipe after anticorrosion treatment of high durability.

4, galvanized corrugated culvert pipe good integrity, plasticity of complex geological conditions on the section of deformation resistance.

5, galvanized corrugated culvert pipe good thermal conductivity to the permafrost area of the subgrade disturbance is small, roadbed stability.

6, galvanized corrugated culvert pipe adopts industrial production, production is not affected by the environment and is conducive to quality control.

7, galvanized corrugated culvert pipe assembly construction, short construction period, light weight, convenient installation, in high altitude area to reduce a large number of manual, and can be constructed in winter.
