石堡川水库位于洛河支流石堡川河上,库容6220万立方米。引水干渠在黄龙山段就跨越沟谷近二十条,其中较大的过沟填方工程10座。这些填方工程高20～30米,长度30～120米,由于施工时削坡不够,清基不彻底或碾压不实等原因,质量较差,不均匀沉陷严重,最大沉陷量在1.2米以上,并产生横向和纵向缝,影响渠道安全行水。如孙西沟填方工程1973年2月建成,6月投入运用,至1979年春,仅在流量3—4米~3/秒时,决口12次之多。 1979年7月开始对10座填方工程采用灌浆加固处理,至1683年9月共灌浆6次,在
Stone Puchuan Reservoir is located in the Luo River tributary of Shi Po River, storage capacity of 62200000 cubic meters. Diversion canal in Huanglongshan section across the valleys nearly 20, of which the larger crossing ditch project 10. These fillings are 20-30 meters in height and 30-120 meters in length. Due to inadequate cutting, lacking of clear base or compaction during construction, the filling quality is poor and the uneven subsidence is serious with the maximum settlement of 1.2 meters Above, and produce horizontal and vertical seams, affecting the safe passage of water channels. Such as Sun Xigou fill project was completed in February 1973, put into use in June, to the spring of 1979, only flow 3-4 meters ~ 3 / s, the Burst 12 times as much. In July 1979, 10 fillings were started with grouting reinforcement and grouted 6 times by September 1683
