Where is the steel plate welded at the end of the reinforcing cage (600-diameter finished product stacking site) used? Is the steel plate welded at the end used for water stop or embedded parts? thank you First of all, this is used for: core grouting and steel bar insertion at the upper end of concrete hollow pipe pile.

After the concrete hollow pipe pile is driven underground, it should be connected with the foundation concrete during the foundation construction. The specific method is as follows:

1, pile hole cleaning-cleaning the mud and water in the hole at the upper end of the pipe pile;

2, manufacturing a reinforcing cage, and welding the reinforcing cage at the bottom with an iron plate slightly smaller than the diameter of the inner hole of the pile;

3, put the reinforcing cage into the pile hole, put down the steel plate, keep part inserted into the pile hole, part exposed pile top (insert

The concrete length and size of the exposed part should meet the requirements of the specification for anchorage length), and after the position is aligned, the reinforcement cage should be fixed with other short steel bars.

Ensure that the reinforcing cage will not move up and down in the subsequent construction;

4. Pouring concrete into the pile hole, vibrating and compacting until the pile top is flat;

5. The steel bars exposed from the pile top will be anchored with the foundation concrete in the subsequent foundation construction.

This steel plate is welded below to prevent concrete from falling down during construction, because the hole of hollow pipe pile is generally tens of meters deep, and the length of concrete to be poured into reinforcement cage is generally only tens of centimeters to one or two meters.

Secondly, if the steel plate is thick and the hoop on the reinforcing cage reaches the top, it is also possible that it is used for burial (because it is used for core filling).

As long as the thickness of the steel plate meets the welding requirements, there is no need to expose the hoop at the top of the pile), but it may also be used for core grouting, and the construction is wrong.

The hoop of the reinforcing cage is pushed by mistake.

Thirdly, if you still see a pipe pile with an inner hole slightly larger than 600 in the excavated foundation pit, then it must be used to fill the core of the pipe pile.
