在使用过程中，将斜拉索本体6的两端通过锚紧装置3进行紧固在一起，然后安装到桥梁上进行工作时，对斜拉索本体6进行通气，使进入的气体从斜拉索本体6的一端进入到另一端，从而实现对斜拉 索进行除湿处理，在安装过程中，斜拉索的两端可以通过锚垫板4安装固定在斜拉索桥上，锚垫板4一端的斜拉索及上、下锚头部分通过保护罩2进行防护，使雨水不易进入两端对其进行腐蚀，同时，将湿度低的干燥空气采用高压气体的方式从通气装置1打入下锚头，从而对下锚头、锚垫板4、固定螺杆等进行除湿处理，另一部分干燥空气从导气管9进入斜拉索本体6内，从而使干燥空气对斜拉索本体6、索导管5、防护套管20等进行除湿处理，干燥空气再从斜拉索本体6另一端的上锚头通气装置1将湿气排出，还有一部分直接从斜拉索本体6内的通孔进入上锚头，对上锚头、锚垫板4、固定螺杆等进行除湿处理，再通过上锚头通气装置1将湿气排出，从而利用干燥空气对斜拉索本体及上、下锚头进行全面的除湿处理，使斜拉索及上、下锚头在长期使用过程中均保持干燥，尽量减少水汽等对斜拉索本体及上、下锚头的腐蚀，能够有效的防止斜拉索的腐蚀发生，全面解决斜拉索本体及上、下锚头易锈蚀的问题，以达到对斜拉索本体桥上的斜拉索上、下锚头及斜拉索本体进行保护，减少斜拉索的维护更换及封桥频率的目的。
斜拉索本体6在携带、使用和安装等过程中，锚紧装置3出口端的斜拉索本体6容易出现弯曲现象，在锚紧装置3的一端设一索导管5，能够有效的防止锚紧装置3一端的斜拉索本体6出现严重弯曲现象，从而提高斜拉索本体6内的通气效果，使斜拉索的除湿效果更好，也能对斜拉索本体6起到导向作用，使斜拉索在制作过程中更加方便。
在使用过程中，通过防护套管20和索导管5的组合，能够有效的对裸露在外的斜拉索本体6进行隔离防护处理，从而使斜拉索本体的防腐蚀效果更好，使用寿命更长，同时，所述索导管5两端各设有一个分别对锚紧装置3出料端的斜拉索本体6和防护套管20进行防护的减震器18，通过减震器18既能够对斜拉索本体6相对于索导管5部分在使用过程中进行减震处理，使斜拉索本体6在索导管5内的定位更加精确，限位效果更好，同时，也索导管5也不会对斜拉索本体6产生碰撞，还能起到密封效果，使斜拉索本体6使用寿命更长。
所述定位筒22固定在锚紧装置3上，在本实施例中，定位筒22通过螺丝固定在锚紧装置3的锚杯16上。锚紧装置3与索导管5之间通过定位筒22转接，通过定位筒22和定位环21的组合，对锚紧装置3一端的斜拉索本体6进行限位紧固处理，从而使斜拉索本体6在使用过程中不会出现分离现象，从而提高每根金属丝的工作效率，所述索导管5的一端设有一连接索导管5与防护套管20的防水套19，防水套19采用热收缩管结构，通过防水套19收缩性原理对索导管5与防护套管20之间的间隙进行密封出去里，从而有效的杜绝空气和水的进入，从而保证斜拉索本体6不会出现受潮而腐蚀的现象发生。
在通过锚紧装置3对斜拉索本体6进行锚紧固定的过程中，斜拉索本体6穿过锚孔14，通过锚孔14前端的锥口进行缩紧后再通过定位环21进行限位，能够使斜拉索本体6通过锚孔14锥口后紧密的靠拢在一起，导气管9插接在斜拉索本体6的中间，能够使空气进入斜拉索本体6后，除湿更加均匀，锚孔14后端锥口的斜拉索本体6通 过锥形孔结构呈放射状分布，当锚孔14后端锥口填入环氧铁砂100后，通过环氧铁砂100对位于锚孔14内的斜拉索本体6和导气管9进行固定，再通过分丝板15对斜拉索本体6上的每根金属丝和导气管9进行分别固定，最后通过锚杯16一端的封板10密封，当环氧铁砂100凝固后，能够使斜拉索本体6、导气管9、分丝板15、锚杯16和封板10形成一整体，通过锚环17相对于锚垫板4进行旋进的过程中，当锚环17一端与锚垫板4接触后，再旋进就能使斜拉索本体6、导气管9、分丝板15、锚杯16和封板10形成的整体向锚环17移动轨迹的反方向移动，从而使斜拉索本体6在使用过程中实现拉紧作用，从而使拉索两端的锚紧装置3在安装斜拉索的过程中，能够对斜拉索本体6内的各根金属丝进行张紧处理，从而使斜拉索本体在使用过程中受力更加均匀。通气装置1靠近斜拉索本体6的一端面与锚紧装置3罩设于保护罩2内的一端面间隔设置，当干燥空气从保护罩2进入后，一部分空气通过封板10能够进行分流，从而使干燥空气对位于防护罩2和锚杯16之间的空间进行除湿处理，另一部分通过通气孔11进入锚杯16内，再从导气管9进入和排出斜拉索本体6，从而实现对斜拉索的整体除湿，结构更加简单，导气效果更好。作为优选的实施方式，锚孔14包括锥孔段，锥孔段靠近封板10一端的孔径大于锥孔段远离封板10一端的孔径。具体的，锥孔段的孔径从锚杯16靠近封板10的一端向远离封板10的一端逐渐减小，斜拉索本体6具有安装于锥孔段内的锥形段，锥形段的形状与锥孔段的形状适配，斜拉索本体6穿过锚孔14，通过锥孔段远离封板10一端进行缩紧后 再通过定位环21进行限位，从而使斜拉索本体6通过锥孔段后紧密的靠拢在一起，位于锥孔段靠近封板10一端的斜拉索本体6通过锥形孔结构呈放射状分布。在具体实施例中，斜拉索本体(6)的长度的延伸方向与通气管(9)的长度的延伸方向平行。优选地，斜拉索本体(6)的中心线与通气孔(9)的中心线重合，这种结构的新型斜拉索的导气管9插接在斜拉索本体6的中间，能够使空气更加均匀地进入斜拉索本体6，除湿更加均匀。通过高压管12和高压管组合接头13的组合接入气体或/和释放气体，能够使接入的气体压力更大，从而使斜拉索内的空气流动性更强，除湿效果更好。
所述保护罩2的一端通过螺母紧固在锚垫板4上，所述锚垫板4与保护罩2之间还有密封圈，能够有效的保证保护罩2与锚垫板4之间的密封效果，从而提高除湿效果，所述斜拉索本体6出气端的通气装置1上设有至少一个传感器7或/和控制阀8，所述传感器7采用温湿度传感器，所述控制阀8采用恒压阀，通过感器7或/和控制阀8对导气管9上出气端进行监测，能够时时的监控并发现斜拉索是否流通问题，能够及时的对出现破损、封堵、腐蚀等现象进行及时的发现并维修，从而使维修效率高，维修成本低。
本发明实施例还提供一种桥梁，包括如上所述的新型斜拉索。该桥梁的新型斜拉索在使用过程中，将斜拉索本体6的两端通过锚紧装置3进行紧固在一起，然后安装到桥梁上进行工作时，对斜拉索本体6进行通气，使进入的气体从斜拉索本体6的一端进入到另一端，从而实现对斜拉索进行除湿处理，在安装过程中，斜拉索的两端可以通 过锚垫板4安装固定在斜拉索桥上，锚垫板4一端的斜拉索及上、下锚头部分通过保护罩2进行防护，使雨水不易进入两端对其进行腐蚀，同时，将湿度低的干燥空气采用高压气体的方式从通气装置1打入下锚头，从而对下锚头、锚垫板4、固定螺杆等进行除湿处理，另一部分干燥空气从导气管9进入斜拉索本体6内，从而使干燥空气对斜拉索本体6、索导管5、防护套管20等进行除湿处理，干燥空气再从斜拉索本体6另一端的上锚头通气装置1将湿气排出，还有一部分直接从斜拉索本体6内的通孔进入上锚头，对上锚头、锚垫板4、固定螺杆等进行除湿处理，再通过上锚头通气装置1将湿气排出，从而利用干燥空气对斜拉索本体及上、下锚头进行全面的除湿处理，使斜拉索及上、下锚头在长期使用过程中均保持干燥，尽量减少水汽等对斜拉索本体及上、下锚头的腐蚀，能够有效的防止斜拉索的腐蚀发生，全面解决斜拉索本体及上、下锚头易锈蚀的问题，以达到对斜拉索本体桥上的斜拉索上、下锚头及斜拉索本体进行保护，减少斜拉索的维护更换及封桥频率的目的。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于发明权利要求的保护范围之内。
