一种桥式滤水管连接结构
[0001]本技术属于桥式滤水管
,尤其涉及一种桥式滤水管连接结构。
技术介绍
[0002]桥式滤水管是一种有桥型孔眼的滤水器材,它在发达国家早已被广泛使用,并取得了令人满意的效果,被誉为“理想的水井过滤器”。主要在水文地质勘探、钻井、凿井施工、水库降水、基础深挖降水、地热开发利用、矿泉水开发利用、低温空调、坏井修复及地下水源取水等活动中使用,由于单根桥式滤水管的长度一般为六米长,而所打孔洞一般可达十几米深,所以一般需要两到三根桥式滤水管组合起来使用,相邻两根桥式滤水管之间通过采用焊接方式连接,若将几根桥式滤水管在场外先焊接组装好,但由于长度太长不利于起吊,所以现有是先将一根桥式滤水管吊入孔洞内,待其上端与地面相平齐时,起吊第二根桥式滤水管,在地面处进行焊接,焊接完成后继续下放,依此类推完成整个桥式滤水管的安装,采用这种焊接的方式极大的增加了下放时间,效率低下,若地质复杂,粉质黏土或水量过大,在等待期极易出现塌孔,影响最后打井效率,增加额外费用。
技术实现思路
[0003]针对上述现有技术的不足,本技术所要解决的技术问题是:如何提供一种桥式滤水管连接结构,其能够大幅减少各桥式滤水管之间连接时间,降低桥式滤水管下放时间,提高工作效率。
[0004]为了解决上述技术问题,本技术采用了如下的技术方案:
[0005]一种桥式滤水管连接结构,包括上级桥式滤水管和下级桥式滤水管,所述上级桥式滤水管的管内下部同轴设有第一环形挡板,所述第一环形挡板底端与上级桥式滤水管底端平齐 ...
