Characteristics and Applications of Manhole Step

What is a Manhole Step

Manhole step is wrapped with high-strength engineering plastic and embedded with high-quality round steel or threaded steel. It has the characteristics of beautiful appearance, good anti slip performance, impact resistance, as well as water resistance, oil resistance, acid and alkali corrosion resistance, and chemical resistance. Can be used for a long time in an environment of -15-100 ° C. It is an ideal alternative to traditional climbing stairs.

Characteristics of manhole step

1. The service life of manhole step should be long: basically 50 years underground and 20 years above ground.
2. The installation of manhole step is convenient: it can be directly embedded into the wall through product pre installation, with accurate and firm positioning, making construction very convenient.
3. Good chemical performance: it should be corrosion-resistant, acid and alkali resistant, and suitable for use in humid, salt spray, acid and weak alkali environments.
4. Non conductive, because some power wells have power cables or other potentially conductive objects. When maintenance workers are working up and down, if there is a leakage or situation, they should be able to safely go up and down without danger.
5. Manhole step are fire-resistant and heat-resistant. For example, the safety ladders currently used are mostly plastic steel ladders, which must also meet the requirements of fire resistance and high-temperature resistance.

The purpose of manhole step

Suitable for various inspection wells, water towers, civil air defense projects, slope subway tunnels, civil buildings, industrial buildings, etc. as fixed up and down stairs.

Installation method of manhole step

According to the size of the ladder, an opening is made on the steel mold and the concrete is poured synchronously. The height between the ladder and the top and bottom can be 30-35cm, and the exposed length of the ladder should not be less than 10cm.

Precautions for manhole step

The installation and construction should be carried out according to the correct usage method, and it is prohibited to climb up and down the ladder before the concrete reaches final setting.
