山东省淄博市淄临区水利局研制出一种氯化铁防水剂水泥砂浆,解决了预制混凝土管接头的技术问题.此法先在接头处铺一层砂浆垫层(水泥:砂=1:3),然后将配有氯化铁防水剂的水泥膏填塞挤紧,再用配有氯化铁防水剂的砂浆(氯化铁:水泥:砂=0.025:1:1),在接头处打一宽8cm、厚2cm的箍,最后覆土养护.这种接头造价低、施工方便,密实度和强度高,防水效果好.(摘自《吉林水利》1990.5)
Zili District, Zibo City, Shandong Province Water Conservancy Bureau developed a waterproof ferric chloride cement mortar, prefabricated concrete pipe joints to solve the technical problems.This method first shop at the joint layer of mortar cushion (cement: sand = 1: 3) Then, the cement paste with ferric chloride waterproofing agent is stuffed tightly and then mortar (ferric chloride: cement: sand = 0.025: 1: 1) equipped with a ferric chloride water repellent is used, A width of 8cm, 2cm thick hoop, the last cover conservation. This joint low cost, easy construction, high density and high strength, good waterproofing. (From “Jilin Water” 1990.5)
