Corrugated Steel Culvert Pipe: 9 Attention Measures For Winter Construction

Steel corrugated culvert pipe is extruded from high-density polyethylene. The inner wall of the pipe is smooth, the outer wall is corrugated, and the inner and outer walls are hollow. Winter low-temperature pipes are harder and less flexible than pipes in other seasons. At this time should pay attention to the construction.


1.Welding temperature

Welding ambient temperature should be no less than -20 ℃, and should take measures to prevent snow, wind and other measures to reduce the temperature difference between the welded parts. Welding joints are strictly prohibited immediately after contact with snow and ice.

2. Measures to prevent icing

Cold weather in winter, in order to avoid the impact of freezing on the pipeline installation construction, the excavated trench should take effective anti-icing measures. On the excavated trench, you can lay some simple grass curtain, discarded cotton clothes and other clothing to avoid trench icing.

3. Concrete matching ratio

When mixing concrete in winter, the proportion and slump of concrete should be strictly controlled, and the aggregate should not be with ice, snow and frozen masses. Before feeding, hot water or steam should be used to rinse the mixer mixing plate or drum. The order of adding materials should be first for the aggregate, water, and then add cement after a little mixing, and the mixing time should be 50% longer than at room temperature.

4. Establish temporary drainage system

When steel corrugated culvert pipes are constructed, drain water in time to avoid accumulation of water during the construction process. Once water accumulates on the construction site in winter, it is easy to freeze and affect the construction progress. Secondly, water will wash away the excavated ditches, causing ditch slope landslides and other consequences.

5. Take drainage measures for the pipe trench

The trench should be drained in a timely and concentrated manner to prevent water from accumulating in the trench. When water accumulates in the ditch, measures should be taken immediately to drain the ditch, remove the softened soil layer that has been soaked through, fill it with sand and gravel, and treat the soil layer in the ditch. Water work in the ditch is strictly prohibited.

6. Choose sunny day

Concrete pouring should choose a sunny day and ensure that it is completed before cooling down, and at the same time, it should be insulated and maintained, and should not be frozen before the concrete strength reaches the design requirements.

7. Concrete out of the machine temperature

Concrete out of the machine temperature should not be less than 10 ℃, its transport equipment should be insulation measures, and should minimize the transport time, into the mold temperature should not be less than 5 ℃.

8. Shorten the construction period

The temperature is low in winter and it is easy to freeze. Constructors should excavate quickly, install quickly and backfill quickly to prevent the impact of freezing on installation and backfill.

9. Concrete insulation measures

Concrete transport vehicles should have insulation measures to minimize the transportation time of concrete.


The above-mentioned steel corrugated culvert pipes need to be paid attention to during winter construction. Although they are all small details, we still need to pay attention. Details decide everything. We are a Corrugated steel pipe Exporter, please feel free to contact us if you need them.
