连城电厂冷却塔地段施工降水井的优化设计

连城电厂厂区地下水含水层埋藏浅 ,透水性好 ,宜采用管井降水为主的降水方案。但因厂区尤其是冷却塔地段上部的填土层主要为卵、漂石 ,结构疏松 ,下部的卵石层混有大块漂石 ,质地坚硬 ,成井的难度很大且成本较高 ,为既满足施工对降水的要求又尽可能少布置降水井以降低成本 ,设计了三种布井方式 ,采用无界含水层干扰井群计算公式反复计算 ,得出最优化的方案。该方案在现场施工中已被充分证明是合理、安全、经济的。

Optimal Design of Pumped Well in Cooling Tower Section in Liancheng Power Plant

It is adaptable pumping water from the tube well to decrease the level of groundwater because the groundwater of Liancheng Power Plant is shallow and permeate quickly The method of pumping water from tube well to decrease the level of groundwater is utilized widely in similar engineering and acquired well effect of engineering and economics It is very difficult and costly to drill the tube well in the cooling tower area of Liancheng Power Plant due to the scattered upper soil of and the hard lower soil made up of pebble and boulder, so the optimal plan that can satisfy the need of construction and decrease the cost was designed by compared three plans The plan utilized in the construction of cooling tower is reasonable and safe and economical
