一、水利工地门塔机的运行特点 水利工地门塔机的运行特点与它的施工特点密切联系着: 第一,建坝需要导流,施工机械的使用因此形成了两个周期,即划分为一期工程和二期工程。 第二,在一个工期里,由于施工对象不同,就有开挖、浇筑和安装三个高峰,施工机械的使用也因此形成了相应的高潮。 第三,由于水利施工有枯水和洪水季节的差别,施工时间观念十分强,任务十分紧,若稍有拖后,一延误就是一年。因此,对使用机械的周期性要求很高。 第四,水利枢纽工程关系到数以万计人民的生命安全和国家财产,质量要求达到100％,因而对施工机械的使用可靠性和完好率要求也很高。
First, the operation characteristics of water conservancy portal crane The hydraulic tower crane operating characteristics and its construction features are closely linked: First, the dam needs diversion, the construction machinery used thus forming two cycles, namely divided into A project and two projects. Second, in one construction period, there are three peaks of excavation, pouring and installation due to different objects of construction. Therefore, the use of construction machinery has also formed a corresponding upsurge. Thirdly, due to the difference between dry season and flood season in water conservancy construction, the concept of construction time is very strong and the task is very tight. If there is a slight delay, a delay is one year. Therefore, the periodicity of the use of machinery is very demanding. Fourthly, the water control project is related to the lives and property of tens of thousands of people and the national property with the quality requirement of 100%. Therefore, the reliability and completeness of construction machinery are also very high.
