Embodiment Construction

[0042] see Figure 1~3 , figure 1 It is a three-dimensional structure schematic diagram of the dredging soft soil rapid consolidation method for land reclamation according to the present invention. figure 2 It is a schematic elevation view of the floating bridge structure of the present invention. image 3 It is a schematic plan view of the floating bridge structure of the present invention. Depend on figure 1 , figure 2 and image 3 It can be seen that the rapid consolidation method of dredging soft soil for land reclamation of the present invention comprises the following process steps:

[0043] Step 1. Pontoon erection

[0044] 1) According to the shape, size and topography of the treatment area, divide the construction unit block, plan the construction pontoon bridge passage, measure and stake out, and generally the area of ​​the unit construction block for dredging soft soil is 10,000 to 20,000 m 2 .

[0045] 2) Erection of pontoon bridges

[0046] Erect floati...

Abstract

The invention relates to a fast consolidation method of blow-filled soft soil for land reclamation, comprising the following process steps of: erecting a floating bridge; paving a plastic woven cloth; paving a main pipe and a branch pipe; inserting a plastic drainage plate; embedding a joint and a vacuum degree meter of a vacuum pump and a pore pressure meter monitoring device; paving a geotextile; paving a vacuum film; distributing the vacuum pump and trying to vacuumize; vacuumizing; monitoring construction; and carrying out vacuum water covering united pre-loading and unloading detection, wherein the step of erecting the floating bridge comprises: erecting the floating bridge on the blow-filled soft soil requiring the treatment and building a construction platform and a channel on mud. The invention has the advantages that construction members carry out operations of paving the plastic woven cloth, inserting the plastic drainage plate, laying pipes, paving the geotextile and the like on the floating bridge, thereby the technical problem that the follow-up treatment on the new blow-filled soft soil cannot be instantly carried out by using the traditional soft soil foundation treatment technology is solved, and 2-5 years for consolidating the new blow-filled soft soil naturally before retreatment are saved.

Description

(1) Technical field [0001] The invention relates to a rapid consolidation method of dredging soft soil for reclamation land reclamation. It belongs to the technical field of ground treatment. (2) Background technology [0002] In recent years, with the rapid economic and social development in coastal areas, the contradiction between the supply and demand of construction land has become increasingly prominent. Developing towards the sea and developing and utilizing the rich tidal flat resources in coastal areas has become the main way to solve the shortage of land resources in these areas. Land development will be the main way of land development in coastal tidal flat areas in the future. The dredger fill in the coastal area is basically silt and silty soft soil, which has the characteristics of high water content, poor permeability, low strength, and personnel and machinery cannot directly enter the site. Conventional soft ground treatment methods cannot be implemented, wh...
