What measures are used to prevent the manhole cover?

With the arrival of the rainy season, including more and more into our field of vision, and prevent the settlement cover, also more and more application of the product, botou tianlong casting manhole cover to prevent subsidence with its superior function of six popular

1. Impact: a u-shaped groove is arranged through the round mouth of the wellhead, and the rubber is synthesized by T, which is embedded in the u-groove, which ACTS as a buffer to reduce the vibration during the process of contact with the well cover.

2. Noise prevention: the contact between the well cover and the well circle is directly applied to the T - type rubber strip, which is designed to eliminate noise.

3, anti-theft, outer cover, a square convex groove, the lining on the cap snap ring through the fixed shaft is connected to the manhole covers, locating pin on the other side of the wall body is fixed, and anti-theft function, when open the manhole cover is placed in a 90 - degree or ideal manhole covers, convenient construction. The lock is made of nylon bushing, never rusting, equipped with special tools, safe and reliable.

4. Anti-skid: the surface of the well cover is composed of a raised 3mm pattern, providing good anti-slip effect.

5. Prevent displacement: the four bolts of the rivets are reserved, evenly distributed at 90 degrees, each using 4 bolts. During the construction process, due to mechanical compaction, it has been eliminated and played a safe role.

Six. Crushing: this is the most characteristic of ductile iron manhole covers. Ductile cast iron manhole cover can withstand pressure 36T / 60T. Light pressure can pressurize 21T. Even if the load pressure exceeds its limit, the ball cap is not as damaged as the normal cast iron manhole cover, but slightly deformed, and has certain safety protection for the car and pedestrians.

In order to prevent accidents, botou tianlong casting produced a new generation of ductile iron anti-theft card pin type manhole cover. Botou tianlong casting products have the functions of shockproof, noise-proof, anti-theft, anti-slip, anti-slip and anti-breakage.
