“七五”攻关项目《截桩技术研究—TK—1型大直径钢筋砼管桩截断机研制及应用》于1991年1月28日在武汉通过国家级鉴定。鉴定确认该项成果达到国际先进水平。目前国际市场上还没有发现TK—1型机的同类产品。用日、荷等国生产的液压桩头砼粉碎机来进行截桩作业时,必需用起重机吊着,砼粉碎后,仍然需用人力去剥离粘附在钢筋上的砼碎块,用氧乙炔火焰切割器割断钢筋和修凿整平桩顶平面,受损的桩顶还要用现浇桩帽包裹起来,因此该产
“Seventh Five-Year” research project “cut pile technology research-TK-1 large diameter reinforced concrete pipe pile cutting machine development and application” in January 28, 1991 in Wuhan passed the national appraisal. Identification confirmed that the achievement reached the international advanced level. At present, no similar products of TK-1 are found on the international market. With Japan, Holland and other countries to produce hydraulic pile head concrete crusher to carry out the operation of cutting pile, it is necessary to use the crane hanging, concrete crushed, still need to use human to peel off the concrete fragments attached to the reinforcement, with oxyacetylene Flame cutters cut steel reinforcement repair and repair leveling the top of the pile, the damaged pile top but also with the pile-wrapped pile cap, so the production
