The damage caused by the long period of the concrete pouring in the mechanical borehole pile
Intraductal XiaBuQu concrete construction of the first said He said do go down If the pipe concrete surface is put forward The broken pile nine times out of ten his find a small strain Knock on look at were at ease
How do you prevent the pile when the underwater concrete is poured? 1, the quality problem and the phenomenon 1) in the pouring concrete process, because the catheter pull out, the mud into the pipe, causes the hole in the hole to decrease rapidly. 2) because the catheter is not well sealed, the mud enters the catheter, and if it continues to be filled, the mud layer will appear in the concrete. 3) the catheter cannot be mentioned because the catheter is embedded too deep, and when the concrete is too long, or when the concrete is plugged into the catheter, it solidifies the concrete of the precast injection. 4) in nondestructive testing, there is a mud layer in one part of the pile.
The length of the pouring cycle may cause a bad adhesion, and a severe fracture may occur.
