Screw thread type freezing pipe through hole water stopping method
The invention discloses a screw thread type freezing pipe through hole water stopping method which comprises the following steps that S1, before a pipe piece through hole is drilled, a protective shell is arranged on a front screw thread of a water stopping device in a sleeving mode, and then freezing pipe drill rod drilling is conducted; a conical head water stop ring is arranged on the water stop device; s2, after the duct piece through hole penetrates through the duct piece on the opposite side and the conical head water stop ring abuts against the duct piece, the protection shell is removed from the front portion of the water stop device; s3, a through hole water stop cover plate is installed on the front portion of the water stop device in a screwed mode, and the through hole water stop cover plate is screwed to abut against the pipe piece; by the adoption of the method, the seams between the freezing pipe in the through hole and the through hole can be blocked on the two sides of the through hole of the pipe piece, water and sand in a water-rich stratum are effectively prevented from penetrating out, the through hole construction risk is reduced, and construction safety is guaranteed; and during drilling, screw threads on the water stop device are protected through the protection shell, and the screw threads of the freezing hole can be prevented from being damaged during drilling.
本发明公开了一种丝扣式冻结管透孔止水方法，包括以下步骤：S1在管片透孔钻孔前，止水装置前部丝扣套设保护壳，之后进行冻结管钻杆钻进；所述止水装置上设置有锥头止水环；S2管片透孔穿过对侧管片后，锥头止水环顶在管片上后，将所述保护壳从止水装置前部移除；S3在所述止水装置的前部丝扣安装透孔止水盖板，并将所述透孔止水盖板旋拧至抵紧在管片上；采用本发明的方法，能够在管片透孔的两侧对透孔中冻结管与透孔之间的缝进行封堵，有效防止富水地层中的水、砂透出，降低透孔施工风险，保障施工安全；且在钻进的时候，通过保护壳对止水装置上的丝扣进行保护，能够防止钻孔时对冻结孔丝扣的破坏。
