越南锦普火力发电厂位于越南广宁省锦普市,装机容量均为300 MW。桩基应用范围为主动力区,包括主厂房、集控楼、锅炉、电除尘、引风机、烟道支架及烟囱,桩数为1800根。桩的形式为冲孔灌注桩,入岩1 m,设计桩径为600 mm,桩长大致在6~12 m之间。资料显示,局部建筑场区下伏基岩石灰岩中存在岩溶现象,受岩溶现象的影响,岩面埋深变化较大,且岩体内无规律的发育有溶洞。基岩面上覆盖层以粉质粘土、粘土以及煤矸石为主。1冲孔前的准备工作
Vietnam Jinpu thermal power plant is located in Quang Ninh Province, Quintiles City, both installed capacity of 300 MW. Pile foundation application area is the main driving force area, including the main plant, control building, boiler, electric dust removal, induced draft fan, flue support and chimney, the number of piles is 1800. Piles in the form of punched and staked piles into the rock 1 m, designed pile diameter of 600 mm, pile length roughly between 6 ~ 12 m. The data show that karstification exists in the underlying bedrock limestone in the local construction site. Due to the karst phenomenon, the rock depth varies greatly, and karst caves are irregularly developed in the rock mass. Bedrock surface cover to silty clay, clay and coal gangue mainly. 1 preparation before punching
