The bottom of the hollow box (12) is connected to the screw (21) by a drive locking assembly (3) for rotating and locking the screw (21).

2. The pipe support structure for a dewatering well of a foundation pit according to claim 1, wherein A corrosion-resistant elastic sleeve (14) can be connected between the hollow box (12) and the support arm (24), and the elastic sleeve (14) wraps the opening on one side of the hollow box (12) and the drive arm (23) inside.

3. The pipe support structure for a dewatering well according to claim 1, wherein The drive locking assembly (3) includes a spline sleeve (31) that is rotatably mounted to the bottom of the hollow box (12). The spline sleeve (31) is connected to the shaft of the screw (21). A spline shaft (32) that meshes with each other is inserted into an opening on one side of the spline sleeve (31). One end of the spline shaft (32) is connected to the side wall of the spline sleeve (33). A spring (34) that is sleeved on the outside of the spline shaft (32) is connected between the spline sleeve (33) and the spline sleeve (31).

4. The pipe support structure for a dewatering well of a foundation pit according to claim 3, wherein The bottom of the hollow box (12) is fixed with a ring plate (36) around the spline sleeve (31). One end of the ring plate (36) and one end of the spline sleeve (33) are provided with a ring of teeth (37) that can mesh with each other. The ring plate (36) and the spline sleeve (33) have a certain distance.

5. The pipe support structure for a dewatering well of a foundation pit according to claim 4, wherein The bottom of the hollow box (12) is fixed with a ring plate two (35) around the ring plate one (36). The ring plate two (35) is provided with an internal thread and a threaded plug (38) is threadedly installed. After the threaded plug (38) is screwed into the ring plate two (35), it abuts against the spline sleeve two (33), and at this time the spline sleeve two (33) meshes with the teeth (37) of the ring plate one (36).

6. The pipe support structure for a dewatering well according to claim 1, wherein An arc plate (13) is connected between the four hollow boxes (12), and the arc plate (13) is attached to the outer wall of the annular sleeve (11) and fixed by screws.

7. The pipe support structure for a dewatering well according to claim 1, wherein A telescopic measuring component (4) is connected between the hollow box (12) and the support arm (24). The telescopic measuring component (4) includes a cylinder (41) rotatably mounted on the side wall of the hollow box (12). A telescopic rod (42) is telescopically slidably mounted on one side of the cylinder (41).
