Steel corrugated pipe culvert is a kind of flexible structure. After it is built, Steel corrugated pipe culvert will form a combined structure with the surrounding soil. It is stressed together. The shape of the Steel corrugated pipe culvert and the backfill on both sides are critical. If the backfill is not dense or has a mold part Hollow or partially large rocks directly act on the pipe body, and there will be large local deformations or local bulges, which poses safety hazards and may cause quality accidents in serious cases. Therefore, the backfilling of both sides of the Steel corrugated pipe culvert and the mold part Strictly control during construction.

1. Steel corrugated pipe culvert construction technology

Foundation excavation—construction put auspicious a foundation potential layer filling a Steel corrugated pipe culvert  installation—sealant painting—asphalt coating—Steel corrugated pipe culvert  backfill—hole paving and slope protection and furnace prevention—preventing the construction of cracks in the end wall of the lake chip stone by assembling steel wave twisted pipe Measures.

1.1 When there are design requirements for the culvert where the Steel corrugated pipe culvert is installed, the foundation should be excavated in accordance with the culvert design requirements of the Steel corrugated pipe culvert， ‘when there is no design requirement, the thickness of the foundation layer and the width of the groove. In order to facilitate mechanical rolling, it is recommended to use the basic standard width.

1.2 The excavation of the foundation pit should be carried out according to the requirements. When the base soil is relatively muddy and other bad soil layers, it should be replaced and over-excavated; if over-excavation, the loose and young parts should be clear, and the treatment plan should be reported to the supervisor, Approved by the design unit.

1.3 The soil foundation pit dug to the elevation shall not be exposed, disturbed or soaked for a long time. The size, elevation, and base bearing capacity of the foundation pit shall be checked in time. After meeting the requirements for installing Steel corrugated pipe culvert , foundation construction should be carried out immediately.
