Specific methods to prevent uneven settlement of steel bellows culverts
In order to prevent uneven settlement of steel bellows culverts, the construction process of foundation pit excavation and substrate treatment is very important.Before the excavation of the foundation pit, the construction of the ground drainage system should be done well, including the construction of a cut-off ditch around the top of the foundation pit, and the setting of a drainage slope with an outward slope between the top edge of the pit and the cut-off ditch to avoid the instability of the pit wall caused by the flow of ground water into the foundation pit; during excavation, slope excavation or step excavation should be carried out according to the excavation depth of the foundation pit, and the elevation of the bottom of the foundation pit should be strictly controlled to avoid over-digging.

Effect of different corrugated culvert, on its service life
Corrugated culvert life is used in working conditions, can guarantee the normal work of the shortest deadlines or number of cycles. Made of corrugated culvert elastic sealing system, often working at varying load to bear more cycle times and larger displacement, so determining the service life of the corrugated pipe culvert, has important significance.
