随着城市建设的发展,地下各种管道工程日益增多。为了避免管道在开槽施工中,拆除地上或地下的建筑障碍,减少破路对城市交通的影响,顶管法施工已经愈来愈多的推广使用,成为城市施工地下管道的主要方法之一。因此,对目前的顶管施工技术,也迫切需要改进提高,以适应对这种施工方法的要求。现将顶管施工中顶进设备的改进一例,介绍于下。一、目前顶进设备的一例从1953年开始使用顶管法施工以来,在顶进设备方面也曾进行过几次改进:一是从
With the development of urban construction, various underground pipeline projects are increasing. In order to avoid the construction of pipelines during the construction of trenches, to remove the construction barriers on the ground or underground, and to reduce the impact of broken roads on urban traffic, the construction of the pipe jacking method has been more and more popularized, and has become one of the main methods for urban construction of underground pipelines. Therefore, there is an urgent need to improve and improve the current technology of pipe jacking to meet the requirements of this construction method. An example of improvement of jacking equipment in pipe jacking construction will be introduced below. I. Currently, one example of jacking equipment has been used in jacking equipment since the construction of the pipe jacking method in 1953.
