Corrugated pipe culvert construction key point

In special environments，corrugated pipe culvert construction should be worked with special treatment.

Rainy Season Construction of Corrugated Pipe Culverts

Strengthen the observation of foundation settlement on the construction site of corrugated pipe culverts, especially in unfavorable areas.

Prevent rain water from soaking the foundation pit. If it is soaked, excavate the soaked part and backfill with the same material as the foundation

Set up water barriers in the foundation pit, to prevent surface water from flowing in. A collection well is installed in the foundation pit, and it should be equipped with sufficient water pumps, and water connection measures are set up in the slope.

After the excavation of the foundation pit on the construction site of corrugated pipe culverts, pour concrete or cushion layer in time. to prevent it from being soaked in water.

Before construction of corrugated pipe culverts, the drainage system should be inspected, dredged or reinforced, if necessary, additional drainage should be added.

After raining, Before pouring concrete, The mud and debris on the form work and steel bars should be removed

Lightning protection measures should be set up in lightning prone areas, and high-rise structures should have lightning protection designs.

The connection of corrugated pipe culvert and Rainproof measures, in the process of installation, when connecting the steel corrugated pipe culverts, the temporary rain canopies should be set up. And it is to prevent rainwater erosion and ensure the integrity and stability of corrugated pipe culverts.

Construction of Corrugated Pipe Culverts in winter or cold areas

1) Pour concrete when the temperature is high during the day, and do not pour concrete at night or when the temperature is low

Mix concrete with hot water to ensure that the outlet temperature of the concrete is not lower than 10 ℃.

The concrete tanker adopts insulation method and is covered with insulation coversthis is to ensure the temperature of the concrete entering the mold, The temperature should not be lower than 5 ℃.

Prepare for construction before pouring concrete, create a smooth flow of work, and ensure the best possible results Complete concrete pouring in a short time.

The poured concrete is first covered with a thin film, and then covered with other insulation materials. About Parts that are particularly susceptible to freezing, covered with insulation materials.

In summery, installing steel corrugated pipe culvert in winter, the environment temperature, concrete construction, transportation and pouring should be paid more attention, as well as the connection of corrugated pipe culvert and power supply and electromechanical equipment, etc. To ensure the standard installation process and long-term stability quality of corrugated pipe culverts
