Ambuklao HP was designed to provide 75 MW of energy to the Luzon power grid.<\/p>\n\n<p>SN Aboitiz Power Benguet, Inc. took over the operation of the power plant and began major rehabilitation and upgrade of the facility. The upstream slope of the dam that suffered a major erosion problem since 1999 when the power plant stopped its operation requires practical and effective erosion protection that can last for the intended design life of the structure. While the downstream part of the dam or the tailrace where impound water enters the Agno River must be able to resist turbulent waters and be heavy enough to prevent hydrostatic uplift.<\/p>\n\n<p>After a comprehensive evaluation of the site conditions and site challenges, Maccaferri Philippines designed a rigid and effective erosion protection system for the upstream and downstream slope of the dam.\u202f<strong>MacFormer<\/strong>, a grout mattress constructed with high strength woven geotextile, was installed to the submerged portion of the upstream slope face to provide protection against rainfall washouts, high speed scour and compensate for the uneven settlement of the underlying soil.\u202f<strong>Galfan-coated\u202fgabions<\/strong>\u202funderlain with<strong>\u202fMacTex\u202fnonwoven geotextile<\/strong>\u202fwas used for the portions above normal dam water level.<\/p>\n\n<p>A layer of MacTex nonwoven geotextile was placed between the MacFormer mattress and the core of the tailrace for separation, filtration, and additional erosion protection.<strong>\u202fIn addition, vegetation can be cultivated within the open areas, allowing an ecological and environmental friendly scenario.<\/strong><\/p>\n\n<p>The work commenced and was completed in 2010.<\/p>\n\n<p><a href=\"https:\/\/www.maccaferri.com\/ph\/contact-us\/\">Contact us<\/a> for more information.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>","protected":false},"excerpt":{"rendered":"<p>An eco-sustainable and effective natural Erosion Control Protection in the upstream slope and tailrace of Ambuklao Dam in Benguet <\/p>\n","protected":false},"author":49604,"featured_media":30939,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_joinchat":[],"footnotes":""},"categories":[1],"tags":[],"class_list":["post-29404","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.0 (Yoast SEO v27.0) -
