طين الحفر المائي - اختبار سلامة خط الأنابيب

تحدي

غالبًا ما يتطلب اختبار سلامة الأنابيب الحفر الهيدروليكي لكشف جزء من الأنبوب للفحص. غالبًا ما تكون طين الحفر الهيدروليكي الناتج منظمًا ويصعب التخلص منه وفي بعض الحالات ملوثًا. في عام 2015، تعاقدت شركة KBL المرخصة من MetaFLO مع مشغل خطوط أنابيب كندي رئيسي في ألبرتا لتوفير التصلب والتخلص من 200 متر مكعب من هذه النفايات.

حل

KBL provided two shale bins placed in parallel at the job site. The hydro excavation trucks offloaded into one of these tanks. With the heavier solids settling at the bottom of the tank, the surface water was pumped to the second tank. The heavier mud was mixed with MetaFLO’s MF006 solidification reagent at a dose appropriate for the whole load. The surface water was then returned to the first tank to finish mixing.

نتيجة

As a result of the MF006 treatment, the hydro excavation material was transformed to the dry, earth like finish in the right photo. This solution required no in-ground sumps, provided optimal efficiency for expensive hydro excavation trucks and low cost disposal options for solid material. Also, the 1% doseage required for solidification with MetaFLO’s reagent, results in a much smaller quantity than would be produced by sawdust or wood chip bulking methods. The client also reduces activities that generate a carbon footprint and mitigates safety and environmental risks associated with shipping large quantities of liquid waste.
