Embodiment Construction

[0036] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0037] Such as figure 1 Shown, the highly saturated heterogeneous dredging fill foundation treatment method of the present invention comprises the following specific steps:

[0038] In step 100, within the entire dredging reclamation site, rolling piles of high rocks along the east-west direction are thrown and filled to form several east-west dyke working faces.

[0039] In step 101, use the east-west dike working face, and then pile up rocks along the north-south direction respectively for throwing and filling, forming several north-south dike working faces, and the entire dredging and filling site forms several blocks.

[0040] Step 102, judging whether there is accumulated surface silt in the block; if yes, proceed to step 103; if not, proceed to step 104.

[0041] Step 103, removi...

Abstract

The invention discloses a processing method for a highly saturated and uneven dredger fill soil foundation. The processing method for the highly saturated and uneven dredger fill soil foundation comprises the following steps that S1, rock blocks are rolled and stacked to carry out dump filling, a plurality of dam work surfaces in the east-west direction and the south-north direction are formed and are inserted, a plurality of blocks are formed in a filling field, and then stone throwing for packing sedimentation, backfilling and pavement are carried out on each block; S2, dynamic compaction and reinforcing processing are carried out on deep soil of the blocks through a high-level or ultrahigh-level dynamic compaction replacement method; S3, full compaction processing is carried out on shallow soil in the blocks through a continuous lapping ram. The processing method for the highly saturated and uneven dredger fill soil foundation is easy and convenient to construct, is reasonable in technology and economy, achieves the processing effect needed by foundation processing, meets the requirements for strength, stability and deformation and effectively improves the unevenness of the soil. Particularly, the processing method can resolve the preprocessing problem in the earlier stage of construction of a field, and achieves the comprehensive functions of foundation processing.

Description

technical field [0001] The invention relates to a treatment method for dredging and filling soil foundations, in particular to a treatment method for highly saturated uneven dredging filling soil foundations. Background technique [0002] Dredging fill is a kind of land area that uses high-pressure water to dredge rivers, lakes and seas or sand from tidal flats through pipelines to hydraulically transport the sand to the shore of the water area to form a land area, and gradually accumulates, flows and deposits. The formed special artificial fill. The soil property of this kind of artificial filling is generally fine-grained silt or silt-fine sand, and at the same time entrains silty clayey soil, which has poor uniformity and low strength. [0003] Due to its special water saturation and structure, the soil has slow settlement speed, long consolidation time, and has drying shrinkage and rheological characteristics. The inhomogeneity of dredger fill is not only manifested in...
