Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a cast-in-place pile grouting pipe. Background Art
[0002] In some areas, bored concrete piles are constructed on the natural floor. After the bored concrete piles are constructed, foundation pit excavation is carried out. The top of the bored concrete pile is located 1 meter above the bottom of the foundation pit after excavation. The grouting process at the bottom of the pile is carried out 3-5 days after the pile is completed. After the grouting is completed, earth excavation is carried out. After the earth excavation, the grouting pipes from the top of the pile to the natural ground level need to be treated. At the same time, the construction workers of the earth excavation also need to pay attention to the grouting pipes from the top of the pile to the natural ground level to prevent the grouting pipes from being damaged, which greatly increases the workload of the earthwork construction workers.
