For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] See also Figure 1-2 In this embodiment, a measuring limit structure for underwater concrete pouring is provided, including a pouring hole 1 and concrete 5. A casing 2 is fixedly installed on the top inner wall of the pouring hole 1. A pouring conduit 3 is provided inside the pouring hole 1. The lower end of the pouring conduit 3 is inserted into the concrete 5. A funnel 9 is fixedly connected to the upper end of the pouring conduit 3. Mud 4 is provided outside the pouring conduit 3, and the mud 4 is arranged in the pouring hole 1. The concrete 5 is arranged below the mud 4. A horizontally arranged metal plate 6 is fixedly installed on the outer surface of the pouring conduit 3 at a position 2-3 meters away from the bottom. An ultrasonic metal detector 7 is fixedly installed at the top position of the outer surface of the perfusion catheter 3, and a metal detection part is provided at the bottom of the ultrasonic metal detector 7, and the metal detection part is located above the metal plate 6. A scale bar 10 is provided on the outer surface of the perfusion catheter 3. By arranging the scale bar 10 on the perfusion catheter 3 and combining the ultrasonic metal detector 7 and the metal plate 6 on the perfusion catheter 3, the position of the perfusion catheter 3 can be accurately determined, thereby facilitating the operation of the operator when lifting the perfusion catheter 3, without relying on the accumulation of experience of the operator, which can greatly The difficulty of operating the pouring conduit is increased, and the safety during construction is effectively guaranteed to avoid the phenomenon of broken piles caused by the conduit being pulled out of the pouring surface.
