埋设永久性的测量标志,要求浇制标石质量要好,时间要快。这里谈谈我组在进行浇制混凝土标石的一点经验。 1.用木料模型板。为了防止脱模时扯滥标石面,我们在打标石之前,模型板先用清水浸透,再用肥皂水抹(一月一、二次)好后才进行工作。 2.把水泥和砂子先合得很匀,然后再慢慢倒水。这样合好的水泥不会起团;慢慢的倒水可以避免水泥浆流走。 Buried permanent measurement signs, requiring pouring stone quality is better, time is faster. Here to talk about my group in the pouring of concrete standard stone experience. 1. Use lumber model board. In order to prevent drafts of standard stone surfaces during demolding, before we typed the stone, the model plate was soaked with water and then wiped with soap and water (January, second and second) before working. 2. Put the cement and sand together well before pouring water slowly. Such a good cement will not play the regiment; slow pouring to avoid the flow of cement slurry away.
