摘要
D型软体排是长江航道整治工程中护底结构的主要工艺,为提高D型软体排的纵向连接强度,减少"撕排"现象以更好发挥护底固沙效果,对D型软体排的纵向连接方式进行了方案设计,并对其中的问题进行试验研究,提出了全新的纵向连接方式,并通过工程实践进行了验证,结果显示14 mm丙纶绳的连接方式基本满足沉排要求。
The D-type flexible mattress is the main technology of the bottom protection structures in Changjiang waterway remediation engineering. In order to enhance the longitudinal linking strength of D-type flexible mattress, reduce the “tearing” phenomenon and better play the effect of bottom protection and sand fix, this paper conducts the program design of longitudinal linking mode, conducts the test study on the problems concerned, proposes the new longitudinal linking mode, and verifies it through the engineering practice. The result shows that the linking mode of φ14 mm polypropylene rope meets the requirement of mattress sinking basically.
