喷射砼是一种多快好省的施工工艺,但目前作为黄土岸坡的衬护尚不多见。1979年11月我们在气温5℃的条件下,在1:0.2的黄土岸坡上进行了喷射砼的衬护试验,衬护厚5公分,砼配合比1:3:3:0.15(水泥:砂子:石子:粘土),未加养护,经过一个冬春进行检查,无异常现象。1980年5月到11月,在荥阳县高山乡余顶大队、穆沟大队进行了喷射砼衬护小型蓄水池的试验,经过几年运用,没有发生什么问题。1983年春又在郑州市郊常庄水库进行了60多亩鱼池的衬护施工,一年多运用没发现裂缝
Jetting concrete is a much faster and better construction technology, but as the lining of loess slope is still rare. In November 1979, we carried out the lining test of sprayed concrete on a 1: 0.2 loess slope at a temperature of 5 ° C with a lining thickness of 5 cm and a concrete mixing ratio of 1: 3: 3: 0.15 (cement: Sand: gravel: clay), unprotected, after a winter inspection, no abnormalities. From May to November 1980, the team from Yuding Battalion and Mugou Brigade, Gaoshan Township, Leiyang County conducted a test of injecting concrete-filled small reservoirs. After several years of operation, no problems occurred. The spring of 1983 and in the suburbs of Zhengzhou Zhuangzhuang reservoir 60 mu of fish pond lining construction, found no more than a year of cracks
