Kutaya
Masamba omangidwa m'mphepete mwa nyanja, ndi ofunika kwambiri opangira ma hydraulic kuti athe kupirira mafunde, mafunde kapena mafunde oteteza gombe.Madzi otsekemera amabwezeretsa ndi kuteteza magombe posokoneza mphamvu ya mafunde, ndikulola mchenga kuwunjikana m'mphepete mwa nyanja.
Poyerekeza ndi kudzaza kwa miyala ya tranditonal, machubu olimba a polypropylene geotextile okhala ndi malo otsika mtengo pochepetsa kutulutsa zinthu ndi mayendedwe.
Nkhani Yophunzira
Ntchito: Chongqing Chansheng River Dredging
Malo: Chongqing, China
Mtsinje wa Changsheng uli m'chigawo cha Chongqing, chomwe chili ndi beseni la 83.4km2 ndi mtsinje wautali wa 25.2km.Mtsinje ukuyenda wakhala woipitsidwa kwambiri kwa nthawi yayitali, ndi mavuto monga eutrophication ya madzi, kuwonongeka kwa mapaipi onyansa, magwero a madzi osakwanira komanso kuwonongeka kwa mipanda, etc. mphamvu yoletsa kusefukira.Mu 2018, boma laderalo lidaganiza zogwiritsa ntchito machubu a geotextile kukokera mtsinjewo.
Ntchitoyi inayamba mu October 2018 ndipo imatha mpaka December 2018. Chiwerengero chonse cha silt chomwe chimagwiritsidwa ntchito mumtsinjewu ndi pafupifupi 15,000 cubic metres (90% madzi).Honghuan geotube yomwe imagwiritsidwa ntchito pantchitoyi ndi mamita 6.85 m'lifupi ndi mamita 30 m'litali.
Monga ukadaulo wosavuta kutsitsa madzi amatope, njira yochotsera madzi ya geotube yadziwika pang'onopang'ono.
Choyamba, matope amawathira ndi flocculant kenako amadzazidwa mu geotube.Dothi loyikidwa likhalabe mu chubu ndipo madzi amatuluka kuchokera mu pores wa chubu.Izi zimabwerezedwa mpaka chubu la geotextile lifika patali kwambiri.
