The invention discloses a soft foundation water passing wharf structure which comprises cast-in-place piles, jet grouting piles and cement soil mixing piles. The cast-in-place piles penetrate througha silt layer, a medium fine sand layer and a clay layer of a wharf, and the multiple cast-in-place piles are arranged around the outer side contour of the wharf. The jet grouting piles are arranged inspace surrounded by the cast-in-place piles, the multiple jet grouting piles are arranged along the arrangement path of the cast-in-place piles, and the jet grouting piles penetrate through the siltlayer, the medium fine sand layer and the clay layer of the wharf. The space surrounded by the jet grouting piles is filled with the multiple cement soil mixing piles, and the cement soil mixing pilespenetrate through the silt layer and the medium fine sand layer of the wharf. Gaps between the adjacent cast-in-place piles are blocked through the jet grouting piles, a soft soil foundation is firmly limited, lateral deformation of the soft soil foundation under the action of vertical loads is controlled, the cement soil mixing piles reinforce soft soil limited by the cast-in-place piles, and the bearing capacity of the soft soil is greatly improved.
本发明公开了一种软基过水码头结构，包括灌注桩、旋喷桩和水泥土搅拌桩；灌注桩穿过码头的淤泥层、中细沙层和粘土层，多个灌注桩围绕码头的外侧轮廓布置；旋喷桩置于灌注桩包围的空间内，多个旋喷桩沿灌注桩的布置路径排列布置，旋喷桩穿过码头的淤泥层、中细沙层和粘土层；多个水泥土搅拌桩填充布置于旋喷桩包围的空间内，水泥土搅拌桩穿过码头的淤泥层和中细沙层；所以相邻灌注桩之间空隙用旋喷桩封堵，将软土地基牢固限制，控制了软土地基在竖向荷载作用下的侧向变形，而水泥土搅拌桩将加固受灌注桩限制的软土，大大提高软土的承载力。
