Municipal road foundation pit guardrail, also known as foundation pit guardrail, is a common safety protection fence on construction sites. However, the following precautions should be taken during construction to ensure that everything is foolproof:

1. To ensure the safety of the pit foundation guardrail, the vertical pole of the pit foundation guardrail should be driven into the ground at a depth of 50-1750px, with a height of 1.2m above the ground. The vertical pole should be set at a distance of 2m, and the distance between the vertical pole and the slope of the pit should not be less than 0.5m.

2. When constructing foundation pit guardrails, if the falling height reaches 2 meters or more, it is required to set up protective facilities such as foundation pit edge guardrails at the edge of the foundation pit.

3. The general requirements for foundation pit guardrails are a total height of 1.2 meters above the ground, 0.06 meters from the ground to the edge guardrail of the foundation pit, a column height of 1.3 meters, and a spacing of 2 meters between the edge guardrails of the foundation pit. The edge guardrail should be able to withstand an external force of 1000N and ensure the stability of the frame.

4. The surface of the foundation pit guardrail column is required to be painted with black and yellow warning paint.

5. The bottom of the foundation pit guardrail should have a 0.2 meter skirting line and be painted with black and yellow zebra shaped warning paint. The safety warning slogan "Beware of Falling" should be hung on the inside of the foundation pit guardrail.

6. The foundation pit guardrail is fully equipped with a dense safety net on the side of the foundation pit, and a safety warning sign "Beware of Falling" is hung in a prominent location, with night warning lights installed.

7. During the construction of foundation pit guardrail, the surface water is controlled to adjust drainage measures and control the surface stagnant water as follows: open drainage ditches are set up along the protective fence around the foundation pit. In order to drain the open water suddenly from the rainstorm in the rainy season and prevent the drainage ditch from not discharging enough, an accumulation tank is specially set up on one side of the foundation pit, and then the accumulated water is pumped to the plant drainage system through the sewage pump in time to achieve organized drainage and ensure smooth drainage.
