Description
Technical field
The utility model relates to a kind of consolidation structure that saturated dredger soft soil is carried out horizontal drainage.
Background technology
In scarce sand ground district, for hydraulic reclamation high-moisture percentage (＞80%), high-ductility index (＞20) reinvent the hydraulic fill foundation of class bury the time, because the characteristics such as soil structure is poor, clay content is high, moisture content is high, compressibilty is high, intensity is low, permeability is low, there is the discharging consolidation weak effect, the problems such as the processing time is very long, and very inhomogeneous, and the foundation strength reliability is low, therefore, generally wanting first airing some months even a few year to carry out treatment effect to barged-in fill can get well again.Processing this class saturated dredger soft soil draining adopts without the in line preloading drainage consolidation method of sand cushion vacuum; In soil layer, plastic draining board is vertical setting, adopt the direct-connected vertical layout plastic draining board of pipeline as vacuum transmission and drainage channel, topping laying geotechnique's bed course and geomembrane, mud or water layer are the top preloading after the overlay film sealing, and basic principle is to utilize the subsidiary stress of upper load and negative pressure of vacuum synergy to accelerate foundation soil to the band drain draining, extracts out vertically upward through band drain again, thereby reduce the water content of foundation soil, improve the intensity of ground.But to new hydraulic reclamation class bury, in the in line vacuum load process, often be formed on native top layer and around compacted zone and the earth pillar protuberance of the 20-30cm thickness of band drain, the formation draining cuts off, it is more difficult that draining and vacuum are transmitted the compared with normal soil body outside the compacted zone, its as a result reality only reinforced sub-fraction foundation soil centered by band drain, other parts do not have consolidation effect substantially.Simultaneously owing to the high-moisture weak soil vacuumized concentrate on surface layer or the band drain, full more water body in the band drain causes vacuum transmission effect under the degree of depth very poor, and the treatment effect of the following soil body of shallow-layer 1m is difficult to the arrival theoretical effect, consumes energy high, and efficient is low.This method also can cause band drain to distort, and hinders draining.
Summary of the invention
The utility model is to overcome the shortcoming that above-mentioned prior art exists, and a kind of saturated dredger soft soil horizontal drainage consolidation structure is provided.
A kind of saturated dredger soft soil horizontal drainage consolidation structure is characterized in that the vertical tube of some row longitudinal arrangements is arranged, and has whenever listed several vertical tubes; Adjacent two classify one minute zone as, and several minutes zone is arranged; Spacing between the two row vertical tubes is 50～125m width; Spacing between adjacent two vertical tubes of every row is 1.6～4m; Caliber 3.5～8cm;
Be communicated with respectively some layers of vertical equity pipe between the bottom of every row vertical tube, top and the vertical tube two ends; Several flexible transverse band drain horizontal cross are arranged between the adjacent two row vertical tubes, and are communicated with corresponding each layer vertical equity pipe; Transverse drainage distance between plates 0.8～2.0m;
Vertical tube, every layer of vertical equity pipe, every layer of transverse drainage plate are interconnected;
By per 800～1000 square metres area one vaccum-pumping equipment 6 is set at top layer, vaccum-pumping equipment is communicated with the top of a vertical tube.
The utility model for hydraulic reclamation high-moisture percentage (＞80%), high-ductility index (＞20) reinvent the hydraulic fill foundation of class bury the time, use as discharge structure.
The utility model can be according to the concrete engineering requirement, at described minute zone along the vertical tube orientation, with the length division unit district of 50～125m; The vertical equity pipe of every layer of both side ends of cellular zone is communicated with by the transverse horizontal pipe; The cellular zone horizontal plane is rectangle or square; Several cellular zones are arranged.Between described adjacent two transverse horizontal pipes, be communicated with by a longitudinal drainage plate.Form thus in length and breadth bi-directional arrangement of band drain.
The utility model when using, can several minutes zone or cellular zone in the layering saturated dredger soft soil.
Use the utility model when dividing minute zone, a vertical collecting well can be set in per 800～1000 square metres zone; Elevation is lower than elevation at the bottom of the hydraulic reclamation district at the bottom of the collecting well; Vertical collecting well is by the pipeline connection horizontal tube.Like this, in work progress, can be to the collecting well draining.
The utility model along the horizontal plastics flexible water drainage of degree of depth arranging multiplayer plate as soil in the horizontal drainage passage, the pipeline that catchments that is connected with the band drain end is as catchmenting passage and negative pressure transmission channels, change the structure of prior art band drain longitudinal arrangement, utilize selfweight stress and negative pressure of vacuum as the power of accelerating draining, thereby reinvent the new hydraulic reclamation ultra-soft of shape clay consolidation process.
The utility model has the advantages that:
(1) utilize the characteristics of dredge fill lifting step by step, the layered arrangement horizontal draining board utilizes the selfweight stress draining of saturated dredger soft soil, and energy consumption is saved than the traditional vacuum precompressed, has accelerated the formation of Soil Body, and the overall duration of tradition is short;
(2) needn't need the top layer of whole treatment region that diaphragm seal and drainage blanket are set such as the traditional vacuum precompressed, can save lot of materials and construction period.
(3) only arrange SLD at the well head that catchments, sealing area is very little, is beneficial to management and control, and energy consumption is low.
(4) between drainage period, band drain can effectively prevent the unfavorable variation of the band drain performance degradations such as band drain bends, well resistance rising with the ground sedimentation.
(5) soil layer thicker upper strata deadweight is larger, and drainage power is larger, and drainage effect is more obvious.
(6) band drain horizontal positioned is the good reinforcement material of barged-in fill, but the bearing capacity of the Effective Raise soil body.
