Alternatives and Reasons for Choosing Concrete Canvas
The initial plan for constructing the irrigation channel was to use traditional methods, such as stone masonry or cast-in-situ. However, because the installation site is located in a rice field area and is inaccessible to four-wheeled vehicles, using traditional methods requires longer construction time, more labor, and higher costs. Therefore, the project owner sought alternative materials that were more effective and efficient. The use of Concrete Canvas provided a solution because this material can be transported to the installation site with the help of labor and is easier and faster to install than traditional methods. This project is a continuation of a project implemented the previous year.
Environmental Conditions
This project is located in a rice paddy area, and access to the installation site is via a footpath. The weather at the time of installation was clear, with no rainfall recorded during the installation process.
Land Preparation
- Clearing irrigation channels of vegetation
- Creating irrigation channel profiles
- Installing wooden formwork
- Digging anchor trenches on both sides of the channel shoulders
Installation, Bonding, and Sealing Methods
CCX-M Concrete Canvas was installed transversely to line the irrigation channel profile. Wooden formwork was used to help shape the channel profile to achieve a neat, uniform shape that matched the design. Due to limited access to the installation site, which consisted only of a footpath, the Concrete Canvas material had to be pre-cut before being transported to the site in smaller sizes. Each small roll of Concrete Canvas used for a channel segment was carried by two workers and placed on the shoulder of the channel to be lined, where the workers rolled it out to form the channel profile. The Concrete Canvas was laid from downstream to upstream of the channel.
The connection method used in this project was screw connection. The screws used were 30 mm stainless steel screws, with a maximum spacing of 10 cm between each screw. Furthermore, 25 cm long J-pins were installed in the anchor trenches on both sides of the shoulder of the channel, spaced 1.8 m apart in each segment.
Hydration Method
The hydration process in this project is carried out using a hose connected to a water pump, with the water source taken from the nearest water source around the irrigation.
Installation Duration
The project was completed in approximately four days, divided into two phases: the first two days in October and the second two days in November. Installation productivity was estimated at approximately 119 m² per day, including site preparation activities such as digging anchor trenches and the Concrete Canvas hydration process.
Project Success
The project was deemed a success, as construction of the irrigation channel continued from the previous year. The owner was satisfied with the speed and ease of Concrete Canvas installation.
