Construction Technology And Project Application Studying Of No-dig Horizontal Directional Drilling Pipe Paving

The technology and method of no-dig horizontal directional drilling pipe paving can be systemic analysis and studying from theory and practice in this paper. The character is aimed at the problem of the no-dig horizontal directional drilling application, which can be analyzed deeply. From the point of view of engineering construction practice, how to improve security and construction quality of no-dig horizontal directional drilling in the under pipe paving, i.e. Using no-dig horizontal directional drilling paving under pipe should be the basis of data collection, stratum analysis and pipe detecting, be theory basic of designing of directional tracking. Construction of directional drilling hole is the key. Slop prepare is the important ensuring of back-dragging successfully.In the way of prophase preparing, this paper emphasizes the importance of full collecting inhering under pipe using no-dig horizontal directional drilling paving in the busy street and emphasizes the exploration technology being the main mean of inhering under pipe. Thus it can provide the main pledge measure of under pipe security and operator security.During the detail construction, this paper emphasized the importance and seriousness of designing tracking. When construction of directional hole, according to the demand of designing tracking, we choose suitable directional drilling machine and control equipment and emphasized the importance of slop prepare during the back-dragging.For the problem of present engineering no criterion market and industry standard disunity of no-dig horizontal directional drilling under pipe paving, the view is put forward in particularity and security of no-dig horizontal directional drilling pipe paving and in reason using of under resource. It emphasizes engineering method data management and unify layout management of no-dig horizontal directional drilling. And it analyzes technology economic and discuss the development of under pipe directional equipment and put forward new thought and studying aspect of no-dig horizontal directional drilling construction engineering criterion management-The effect of all kinds of tache and factor in the different no-dig directional drilling construction are discussed from a great deal of detail no-dig engineering examples.
