在山丘地区的水利建设中,采用装配式结构时,由于运输和吊装重件不便,构件过重往往致使采用装配式结构成为不可能或很不经济。因而要解决的突出问题之一,就是如何尽可能地减轻预制构件的重量。为此,我们在赣县经旗水库大渡槽采取了薄壁预制槽身,并进行了试制工作,取得了一些初步成果。经旗水库槽身和支墩排架,均采用预制装配式结构。槽身采用加筋钢丝网水泥轻型桔构,排架等构件计划采用钢筋混凝土预制构件。本文仅就试制成功的(10.0米跨度〕加筋钢丝网水泥轻型槽身作一介绍。一、钢丝网水泥的特性钢丝网水泥是一种新的复合材料,它是利用匀质性较好的高标号细集料混凝土(水泥砂浆一般R_(28)=300～700公斤/厘米~2)和分散性很高的钢丝网组成的。由于钢丝的直径较小,表面积大,与砂浆
In the case of water conservancy construction in hill areas, the use of fabricated structures, due to the inconvenience of heavy lifting and lifting loads, tends to make the use of fabricated structures impractical or uneconomical. Therefore, one of the outstanding problems to be solved is how to reduce the weight of prefabricated components as much as possible. For this reason, we adopted the thin-wall prefabricated tank body in the Jingdezhen Reservoir reservoir aqueduct and conducted trial production work, and achieved some preliminary results. The flag reservoir tank body and pier mounts, are prefabricated assembly structure. Groove body reinforced steel mesh with light orange structure, frame and other components planned to use reinforced concrete prefabricated components. This article only on the successful trial (10.0 meters span) reinforced steel mesh lightweight light tank made an introduction.First, the characteristics of steel mesh steel mesh cement is a new composite material, which is the use of better homogeneity High-grade fine aggregate concrete (cement mortar general R_ (28) = 300 ~ 700 kg / cm ~ 2) and highly dispersed wire mesh composition.Since the wire diameter is small, the surface area, and the mortar
