求翻译：由于本工程桩顶埋深较大、桩基大部分是按抗拔桩设计，桩基施工时务必采取有效措施，防止土体大量涌入管桩空心内部，影响将来的灌芯质量。是什么意思？

As the project is top of the pile depth larger pile most of the uplift pile design, pile foundation construction must take effective measures to prevent soil from the influx of the pipe pile hollow internal, influencing the future quality of grouted.

This works because the buried deep piles are large, most of them are piling on piling anti-pull design, pile construction, be sure to take effective measures to prevent the influx in piles, affected in the future a hollow inside the tank core quality.

Because of this engineering pile top embedded depth large, mostly as uplift pile design of piles, pile base construction must take effective measures to prevent the influx of soil pipe piles of hollow internal, influencing the future-filled quality.

Because this project head of pile burying depth is big, the pile foundation majority is according to the anti-pile pulling design, when pile foundation construction takes the effective action by all means must, prevented the soil body inrushes the steel pipe driven in as piling massively hollow in,
