The speed bump is almost always seen by people who cross the road. It is not unfamiliar in our lives. It is a kind of traffic facility used to slow down. Below I will introduce the construction method of the speed bump. Let’s take a look. :

General installation method of cast steel deceleration belt: installation is more convenient, usually any combination of standard blocks and advanced "internal expansion anchoring technology" are used to firmly fix it on the ground with screws, and the installation is firm, stable and reliable. Will loosen.
The speed bumps are installed on the asphalt pavement: 1. Arrange the speed bumps neatly into a straight line (black and yellow), and place a semicircular row end at each end. 2. Use a percussion drill to install a 10mm drill bit to drill a hole vertically at each installation hole of the speed reducer, with a depth of 150mm. 3. Fix it with a long nail with a length of 150mm and a diameter of 12mm.

The cast steel speed bumps are installed on the cement road: 1. Arrange the speed bumps neatly into a straight line (black and yellow), and place a semicircular row end at each end. 2. Use a percussion drill to install 14 drills vertically to drill holes in each installation hole of the deceleration belt, with a depth of 150mm. 3. Drive in the inner expansion bolts with a length of 120mm and a diameter of 10mm, and tighten them with a 17 hex wrench.

Cast steel speed bumps are generally installed in places with a lot of traffic and people to slow down the speed of driving and ensure that the person is not dangerous. It also makes a huge contribution to the traffic industry. Therefore, we must Cherish our public facilities!
