Abstract

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.

Description

technical field [0001] The invention relates to the field of wharf construction, in particular to a soft foundation water-passing wharf structure. Background technique [0002] The wharf built along the river bank is often covered with soft soil such as silt, which is prone to problems such as excessive settlement deformation and uneven settlement, which will have a negative impact on the stability of the wharf structure. The superstructure cracked and even collapsed. For working wharves used by water affairs or maritime law enforcement ships, because they are only used by staff and have a small load, structural safety issues are ignored, and cracks and collapses often occur, affecting normal use. Contents of the invention [0003] The purpose of the present invention is to provide a soft foundation water-passing wharf structure to solve the problem of insufficient security of the existing soft foundation reduction wharf. [0004] In order to solve the above-mentioned te...
