New-design concrete wall to protect banks against erosion
16 July 18 - The Directorate of Water Resources and Improvement of River System (Mandalay Region) said it has built retaining walls in Amarapura and Ngazun townships in Mandalay Region using a new design for the first time.
The department carried out 19 projects to sustainably protect river banks against erosion along the Ayeyawady River in Mandalay Region with the use of the region's budget for the 2017-2018 financial year. It used a new design that is quite different from the traditional method of constructing a gravel-filled wall. The builder used many six-inch-thick concrete blocks to build the new walls.
U Toe Aung Lynn, director of the department, said such kind of retaining walls will be built in suitable areas over the following financial years based on the fruitful result of this project. The new method is appropriate for the areas beside the Dohtawady River and some villages along the Ayeyawady River.
The foundation is crucial in building a strong retaining wall. Without a strong foundation, the walls will be insecure. Each concrete block has two holes, which help plants get water to grow naturally, he added.
Two-thirds of Phayegyun Village had experienced river bank erosion before the new concrete retaining walls were built. The region's Directorate of Water Resources and Improvement of River System has already submitted a proposal to carry out river bank protection projects with an estimated cost of Ks5 billion across 15 sites in the 2018-2019 fiscal year.—Khine Hsat Wai
