土工膜防渗处理是调蓄水池充分发挥性能的关键

近年来，经济和城市化建设的发展日益加快，缺水问题得到了很大的缓解和改善，在早些年缺水问题困扰很多地区，尤其是落后偏远地区的大问题。为确保供水的连续性及安全性，修建能够起到调节作用的调蓄水池是切实可行的措施。

调蓄水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)的容量需根据水(shui)(shui)(shui)(shui)(shui)(shui)利工(gong)(gong)(gong)程的规模、成本投入、施工(gong)(gong)(gong)周边(bian)的自(zi)(zi)然(ran)环境、地(di)理情(qing)(qing)况及后期维修(xiu)等(deng)综合(he)情(qing)(qing)况确定，常(chang)用的形(xing)式(shi)有混(hun)凝土面板结构、格梁混(hun)凝土结构等(deng)，也(ye)有根据自(zi)(zi)然(ran)地(di)形(xing)开挖(wa)，再做防渗处理的形(xing)式(shi)。整(zheng)个工(gong)(gong)(gong)程分为水(shui)(shui)(shui)(shui)(shui)(shui)源工(gong)(gong)(gong)程、供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)工(gong)(gong)(gong)程及附属工(gong)(gong)(gong)程三(san)大(da)系统。水(shui)(shui)(shui)(shui)(shui)(shui)源可谓(wei)是(shi)工(gong)(gong)(gong)程的源头，至(zhi)关重(zhong)要，仔细筛(shai)选后选择了金强(qiang)河干流(liu)上游处引水(shui)(shui)(shui)(shui)(shui)(shui)，通过枢纽进(jin)行(xing)调节用水(shui)(shui)(shui)(shui)(shui)(shui)，并采(cai)用管(guan)网(wang)输(shu)送的方(fang)式(shi)，将金强(qiang)河的水(shui)(shui)(shui)(shui)(shui)(shui)经引水(shui)(shui)(shui)(shui)(shui)(shui)骨干管(guan)网(wang)汇聚到约9.8万m3的调蓄水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)内，由调蓄水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)调流(liu)调压(ya)系统进(jin)行(xing)供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)网(wang)控制，输(shu)送进(jin)供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)管(guan)网(wang)系统，以(yi)自(zi)(zi)压(ya)供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)的形(xing)式(shi)流(liu)入当(dang)地(di)农(nong)田。自(zi)(zi)该调蓄水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)工(gong)(gong)(gong)程竣工(gong)(gong)(gong)并正式(shi)运行(xing)以(yi)来，将灌(guan)区大(da)田灌(guan)溉供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)保证率由50%提(ti)高(gao)至(zhi)75%，温室大(da)棚(peng)灌(guan)溉供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)保证率提(ti)高(gao)至(zhi)85%，年灌(guan)溉供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)量达2991万m3，对(dui)促进(jin)地(di)方(fang)经济发展起到了重(zhong)要作用。

现代(dai)社会经济高速发展(zhan)(zhan)，人民群众对(dui)生(sheng)活(huo)质量的追求也日(ri)益增高，因此(ci)，对(dui)生(sheng)活(huo)用水(shui)的需求量也越来越大，不断完善水(shui)资源系统(tong)至(zhi)关重(zhong)要(yao)(yao)，水(shui)利工程基础建(jian)设(she)需要(yao)(yao)在新(xin)时代(dai)的发展(zhan)(zhan)中不断创新(xin)，大力发展(zhan)(zhan)智慧水(shui)利。
