[0012] 2. This utility model exposes the internal pouring groove between the two locking half-pipes by opening them, allowing the mixed concrete to enter and fill the pouring groove. Then, the two locking half-pipes are closed, causing the internal concrete to harden and fix the two locking half-pipes, the first thin pipe, and the second thin pipe. This seals and rigidly fixes the joint between the first thin pipe and the second thin pipe, thus forming multiple concrete pipes into a whole that can be stably buried in the soil and has a stronger ability to resist local soil deformation.
