How to Create a Cunette Effectively?
Introduction:
"Creating an effective drainage channel is essential to facilitate the flow of wastewater within manholes. In this tutorial, we will guide you step by step through positioning an inspection chamber, ensuring the correct placement of the pipe, and finally, how to install an effective drainage channel."
Manhole Positioning:
When installing the inspection chamber, it is crucial to respect the alignment axes to ensure optimal flow. These axes are marked using a chalk line on the concrete base, guaranteeing precise positioning.
Openings and Pipes:
The openings for the pipes are crucial. Using two mallets, one to break the existing structure and the other to prevent chipping, the inspection chamber is prepared. The pipe, which must extend 50 cm beyond each side, is then carefully positioned.
Installing the Drainage Channel:
Creating an effective drainage channel involves two main steps. A first layer of lean concrete is laid, followed by a layer of mortar with a specific mix for the finish. A 10% slope is recommended to effectively guide the runoff.
Conclusion: Gutters, these masonry structures, are vital for optimal runoff. With the right techniques and strict adherence to the steps, their installation becomes child's play.
