机制钢筋混凝土管(简称机制管)强度较高,管壁不易漏水。在小水库和渠系配套建筑物工程中,有许多建筑物可用机制钢筋混凝土管。它比现场浇筑混凝土管质量好,施工进度快,节省模板。湖北省有些水利工程上,正在推广机制管。现将各地使用机制管的技术经验和应注意的问题,简述于下,以供参考。(一)机制管的施工安装一、机制管的埋设方式和受力情况一般埋设管子方法可分为沟埋式(如图1)和平埋式(如图2)。沟 Mechanism Reinforced concrete pipe (referred to as the mechanism tube) high strength, difficult to leak the wall. In the construction of small reservoirs and canal systems, there are many structures available for the mechanism of reinforced concrete pipe. It is better than the cast-in-place concrete pipe construction, construction speed, save the template. Some water conservancy projects in Hubei Province, is to promote the mechanism tube. At present, the technical experience and attention should be paid to the technical experience of using mechanism pipe in various places for the following reference. (A) the construction and installation of mechanical pipe First, the mechanism of the buried pipe and the stress situation Generally buried pipe method can be divided into trench buried (Figure 1) and buried (Figure 2). ditch
