喷头一转 清凉一夏
林都园林兴环项目创新高边坡喷灌养护系统
时间:2020-08-04 阅读:次

面对水车无法对高边坡草木进行有效喷水养护的难题,林都园林公司承建的兴义环城高速公路景观绿化项目汇聚众智,利用一个小小的喷头创新,于近日成功攻克难关,实现边坡生态修复、景观绿化的效果。

在兴义环高绿化合同段K18+066-K19+660处,左侧边坡共6级,平均每级高度12米左右。因边坡较高,常规的水车喷水射程不够,导致边坡已发芽生长的草得不到有效灌溉。

项目管理人员看在眼里、急在心里,发动大家集思广益,多次讨论、研究解决问题的方法,最后决定仿农业喷灌系统进行养护试验。主要措施为:在三级及以上边坡上沿铺设主管50毫米的PVC管,每隔6-8米设置一个旋转喷头,每级坡面管道均设置一个总闸阀;用柴油机作为动力装置,用离心式水泵进行泵送。启动动力装置并泵送到位后,打开闸阀进行边坡喷灌。

经过试验,该喷灌系统取得良好效果——喷灌可完全覆盖相邻喷头之间的区域;蓄水容积大,喷灌一级边坡可持续50分钟,完全达到养护要求;对边坡坡面冲刷较小,水滴打击强度可控,避免对成品工程营养基质和种子(小苗)等的冲刷,减少水土流失;喷灌坡面均匀程度较常规水车养护更胜一筹,能更好地为草、灌生长提供有利条件,大大提高边坡绿化成效,加强边坡生态植被的恢复。
