Abstract
The invention discloses a treatment method of extensive dredging dredger fill foundation and its infiltration pipe. The treatment method contains the following steps: firstly, set the infiltration pipe (2) vertically on the dredger yard (5) and divide (5) into at least two dredger areas. Then, dredge the muddy dredger fill (3) into the dredge areas. Finally, set artificial hard shell (1) on (3). The head of (2) extends into the upper surface of (1). The treatment method in this invention firstly divides the extensive dredger yard into small areas and dredges simultaneously to improve the efficiency of foundation treatment. Setting discharge channels before dredging can realize dredging and discharge consolidation simultaneously instead of treating after dredging, which shorten the time to enhance the foundation strength.
Description
Technical field
The present invention relates to a kind of barged-in fill foundation treatment technology, relate in particular to a kind of large tracts of land dredging barged-in fill method for processing foundation and soakaway trench thereof.
Background technology
Along with the mushroom development of coastal cities expanding economy and city infrastructure, the situation of land-based area deficiency appears in more domestic harbours, and the mud that dredging is come out is used for sea reclamation, has become the important means of coastal cities land development.Correspondingly, the geotechnical engineering problems relevant with barged-in fill is more and more outstanding, and key problem is the processing of barged-in fill, at present, mainly contains methods such as two ash stakes, deep-mixed pile, piling prepressing, vacuum preloading for the reinforcement measure of barged-in fill ground.But because barged-in fill ground soil property is too poor, fixed performance is bad again, uses two ash method and deep-mixed pile method often not ideal; And preloading and vacuum method need fixed naturally through 1～3 year of barged-in fill ground, therefore, necessaryly in the hydraulic reclamation process it are carried out certain pre-consolidation process.
Summary of the invention
The invention provides a kind of discharging consolidation that can quicken ground, shorten foundation strength large tracts of land dredging barged-in fill method for processing foundation and the soakaway trench thereof of rise time.
The present invention adopts following technical scheme:
A kind of large tracts of land dredging barged-in fill method for processing foundation, this processing method may further comprise the steps:
1. soakaway trench vertically is set on blast-filled ground, and blast-filled ground is divided at least two hydraulic reclamation zones,
2. with mud matter barged-in fill hydraulic reclamation to the above-mentioned hydraulic reclamation zone,
3. on mud matter barged-in fill, artificial crust layer is set, and the opening of soakaway trench extends to the upper surface of artificial crust layer.
A kind of soakaway trench that is used for large tracts of land dredging barged-in fill method for processing foundation is provided with the hole on the surface of this soakaway trench.
Compared with prior art, the present invention has the following advantages:
1, the present invention can quicken the discharging consolidation of ground, shortens foundation strength rise time.Processing method of the present invention at first is divided into pocket with large-area blast-filled ground, carrying out hydraulic reclamation simultaneously handles, improved the efficient that ground is handled, simultaneously, just set drainage channel before native hydraulic reclamation, the limit hydraulic reclamation just can the limit discharging consolidation like this, rather than native hydraulic reclamation is well handled again, shorten foundation strength rise time, playing a multiplier effect aspect soil body discharging consolidation and the foundation strength growth.
2, the present invention can reduce the construction costs cost.Because the present invention is provided with artificial crust layer on mud matter barged-in fill, and artificial crust layer seeps water hardly, simultaneously because the wall of the soakaway trench that uses is provided with the hole, then the water in the barged-in fill is discharged fast at deadweight effect lower edge soakaway trench, and gather soil layer top, then the water of Pai Chuing directly is covered in the loading that becomes preloading on the soil layer, employs other objects with regard to not needing in addition for preloading, both make things convenient for construction, reduced the construction costs cost again.

The specific embodiment
Embodiment 1
A kind of large tracts of land dredging barged-in fill method for processing foundation, this processing method may further comprise the steps:
1. soakaway trench 2 vertically is set on blast-filled ground 5, and blast-filled ground 5 is divided at least two hydraulic reclamation zones,
2. with mud matter barged-in fill 3 hydraulic reclamations to the above-mentioned hydraulic reclamation zone,
3. artificial crust layer 1 is set, and the opening of soakaway trench 2 extends to the upper surface of artificial crust layer 1 on mud matter barged-in fill 3.
In the present embodiment, soakaway trench 2 becomes four zonules with the hydraulic reclamation region separation after vertically placing.
A kind of soakaway trench that is used for large tracts of land dredging barged-in fill method for processing foundation is provided with the hole on the surface of this soakaway trench 2, and is coated with filter screen at the external surface of soakaway trench 2.
Claims (3)
1, a kind of large tracts of land dredging barged-in fill method for processing foundation is characterized in that this processing method may further comprise the steps:
Soakaway trench (2) 1. vertically is set on blast-filled ground (5), and will be divided at least two hydraulic reclamation zones on the blast-filled ground (5),
2. with mud matter barged-in fill (3) hydraulic reclamation to the above-mentioned hydraulic reclamation zone,
Artificial crust layer (1) 3. is set, and the opening of soakaway trench (2) extends to the upper surface of artificial crust layer (1) on mud matter barged-in fill (3).
2, a kind of soakaway trench that is used for the described large tracts of land dredging of claim 1 barged-in fill method for processing foundation is characterized in that being provided with the hole on the surface of this soakaway trench (2).
