Description

一种铠装排泥管的设计方法及其排泥管 技术领域
本发明涉及疏浚工程中使用的有关装备技术领域，尤其涉及一种用于疏浚工程的铠装排泥管的设计方法及其排泥管的技术领域。
背景技术
河道、航道、港池浚深、海港浅滩、码头基槽等机械疏浚工程都需要大量的排泥管连接而成的排泥管线来实现输送，而在整个排泥管线中不可缺少的用于调整排泥管线方向的排泥弯管，至今大部分一直使用的自浮式排泥橡胶管，由于自浮式排泥橡胶管在输送如岩石、珊瑚礁、矿石等有锐缘的固体物料时很快会被磨穿，失去使用价值，而将导致整个疏浚工程系统停工，进行修复或整根排泥管线报废，耗费宝贵的施工时间和较高的管线维修费用。为解决这一技术问题，进一步改进自浮式排泥橡胶管所存在的技术缺陷，国家知识产权局2011年03月02日公开的专利号为：ZL201020214517.8的技术方案和2009年12月02日授权公告的专利号为：ZL200920036395.5的技术方案都为解决背景技术中存在的技术缺陷，在提高耐磨性能方面采取了在胶管的最内层增加耐磨性能好的有机胶粘剂和耐磨钢环的技术方案，为提高自浮式排泥橡胶管的使用寿命提供了新的技术措施。但是由于自浮式排泥橡胶管本身所存在的产品缺陷而致使存在如下不足之处：其一是自浮式排泥橡胶管虽然具有一定的弯曲性能，但是由于调整排泥管线方向的弯曲度是靠由里到外的整体变形的方案来实现的，这种变形对于自浮式排泥橡胶管来说是靠管体各个部位的弹性变形来完成的，而各个部位的弹性变形对于管体的同一圆周截面来说，又存在着拉伸和压缩的双重受力，因而这一技术方案本身存在着在没有弯曲外力的条件下，自浮式排泥橡胶管靠本身橡胶制品的弹性变形量是无法保证达到弯曲度规定的要求的缺陷，特别是在与捆绑式托浮金属排泥管配套使用时所显示出的不配套的缺陷更为突出；其二是自浮式排泥橡胶管通过在胶管的最内层增加有机胶粘剂和耐磨钢环的技术方案来提高橡胶管的耐磨性能，当该自浮式排泥橡胶管在使用过程中，被输送的固体物料在一个由有机胶粘剂和耐磨钢环组成的输送管道内反反复复的运行，由于有机胶粘剂和耐磨钢环制成的内壁会被固体物料反复碰撞，有机胶粘剂和耐磨钢环的磨损程度是不一样的，这不仅会发生输送阻力影响输送速度，而且也会直接影响到使用寿命，由于内管壁耐磨损性能不一致难以与更好的金属复合排泥管配套使用，特别是在作业环境更为恶劣条件下输送矿石、南海输送珊瑚礁的作业时，这种不配套现象就表现得更为突出；因此，如何在现有技术的基础上提供一个新的设计方法，对排泥管线进行新的设计并制造一种铠装排泥管既满足用来调整排泥管线方向的用途，同时又能达到与金属复合排泥管的耐磨性能相接近，全面提高金属排泥管的使用寿命，降低疏浚工程的生产成本，提高企业经济效益，这对于本技术领域的技术人员来说确是一个亟待解决的技术课题。
