该装置包括一穿透上部覆盖土层插入到海底深埋砂土层的钻孔套管，在钻孔套管内，设有进气管、排砂管和振动连接管；进气管和排砂管的下端连接一个吸砂头；振动连接管的下端连接振动头；吸砂头由一中心腔室、环状腔体和吸砂管构成。

The reticulated vessel which has large cavity has thicker wall due to more elastic fibers and more smooth muscles and its endothelium is cuboidal epithelium which has rotundity karyons. But the reticulated vessel which has small cavity has thinner wall due to less elastic fibers and less smooth muscles and its endothelial cells are flat epithelial cells which have long-shuttle-shaped karyons. In some regions, the ducts are very small in diameter and thin of wall, and they become blood sinus in the end.

管腔大者，管壁厚，弹性纤维、平滑肌纤维多，内膜靠腔面内皮细胞多成立方状，细胞核端位近圆形；管腔小者，管壁薄，弹性纤维、平滑肌纤维少，内皮细胞扁平、排列稀疏，胞核长梭形；一些区域管径极小，管壁极薄，成为开放的血窦，只允许一个血细胞通过。
