Technical Field

[0001] The utility model relates to the technical field of steel cylinder concrete pipe opening, in particular to a lining type prestressed steel cylinder concrete pipe opening device. Background Art

[0002] With the vigorous promotion and widespread use of PCCP in China, medium and small diameter prestressed steel cylinder concrete pipes have attracted more and more attention from users. However, in actual projects, there are often deviations between pipeline design and actual water supply range, such as the addition of residential areas or corporate water supply outside the original design water supply range, or changes in pipeline design caused by on-site buildings or structures, requiring additional branch pipes. At present, for the form of additional branch pipes, steel tees are usually used to replace the original pipes;

[0003] In the existing method of adding branches, workers are required to use a handheld hole-opening device to mark and drill holes on the upper end of the pipe body when the water supply to the pipe is cut off. However, when using this method, the handheld drilling method is prone to poor drilling stability and low drilling quality, so how to optimize the quality of the hole is something we need to consider.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] A threaded rod lift is set to make the downward drilling work more stable and the quality of drilling is improved. The use of a ring laser light can be used to pre-position before drilling to avoid drilling offset. In addition, an electric telescopic rod is provided to adjust the position of the drill bit and change the position of the drill bit from the vertical plate. Combined with the use of a screw rod lift, it can meet the needs of drilling holes on the upper end of pipes with different radii, thereby improving the overall adaptability of use.
