Corrugated steel pipe culvert suitable terrain：

1. The Corrugated steel pipe culvert can be used to replace the bridge and culvert in the gully of mountainous and hilly areas, which has the advantage of fast construction speed and cost saving.

2, mountain high fill can use Corrugated steel pipe culvert  construction.In the high fill highway construction, due to the transportation of building materials, the site to the bottom of the ditch and other difficulties and can not build temporary pavement can use Corrugated steel pipe culvert half construction 'installation speed' construction period is short and other characteristics, but also can avoid due to backfill caused by uneven settlement and other problems.

3, highway construction in coal mine goaf, due to an underground goaf can cause varying degrees of decline, uneven settlement, produce different degrees of damage to general concrete structure, steel corrugated pipe culvert is a kind of flexible structure, corrugated pipe has excellent characteristics of lateral displacement of compensation in the structure, can give full play to the steel tensile performance is strong, the characteristics of deformation of superior performance,It has great resistance to deformation and settlement, especially suitable for soft soil, expansive land, collapsible loess foundation bearing capacity is low and earthquake prone areas.

4. In the case of low foundation bearing capacity, there is no need for special treatment of the foundation, as long as a certain thickness of sand and gravel cushion is replaced.

5. Partial rainstorm is more frequent in some areas, which is easy to damage the bridge and culvert structures, and the concrete structures cannot be reused after being washed out. New culverts must be built, resulting in broken ties and rebuilt, increasing the construction cost and long construction time, and the bellows can be reused after water damage.

6, old culvert quick repair project;

Due to the uneven settlement in some areas, culverts are damaged to varying degrees, such as stone arch culverts. It takes a long time to dig out and repair the culverts in the high fill areas, and it will increase the cost to break off the traffic or build the pavement. It is difficult to construct the cement round pipes embedded in the culverts, and it is difficult to fill cement mortar between the pipes and the old arch culverts.

The use of bellows culvert can be connected outside the culvert after the advance, no gap at the joint;

A hole is made on the side of the pipe for filling with schist and mortar to increase the integrity of the pipe culvert and the original culvert;

In addition, the bellows tube body is light and easy to construct;

During the construction, the foundation should be cleaned while pushing forward to ensure the safety of the construction personnel.

7. When there is no access road along the mountain danger, the use of bellows can be divided into construction, to ensure the opening time in advance.

8. When shallow filling, corrugated culvert can be used for construction.

Because of the shallow filling soil, the cement circular culvert is prone to crack in the construction process. The bellows is a kind of flexible structure, which can adapt to the requirements of deformation and the passage of heavy load vehicles.

9, instead of small bridge using bellows porous use.

10. When the two roads intersect, the steel corrugated plate channel can be used.
