Background technology
Along with China coast rapid development of economy, construction land day is becoming tight, and the mud that the cleaning of coastal, riparian area navigation channel brings usually cannot process, and based on this, large-area reclamation by pumping filling becomes the important method solving problem above.But, the features such as the mud of hydraulic reclamation has moisture content height (usually can reach 200%) recently, void ratio is big, intensity is low, if consolidation forms certain intensity under weight stress, then need the time of 1 to 2 years, this will have a strong impact on the duration, it is therefore necessary to it is processed.
The method generally adopted is vacuum preloading, and for the process in the place after hydraulic reclamation, the method being substantially the high-order evacuation of employing, vacuum load can not be efficiently transferred in mud.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of vertically solid drainage arrangement and using method reinforced for blowing-filling sludge.
For solving above-mentioned technical problem, the present invention provides a kind of vertical three-dimensional drainage arrangement reinforced for blowing-filling sludge, including filter membrane, pvc pipe and four-way, it is characterized in that, described pvc pipe is provided with hole, described filter membrane is enclosed within pvc pipe, and the pvc pipe that several are cased with filter membrane is connected to design length by the major joint up and down of four-way several described, and the left and right branch joint of described four-way also connects the pvc pipe being cased with filter membrane.
Further, the angle of described four-way is 45 degree.
Further, described pvc pipe two ends are provided with joint for connecting four-way.
Further, it is positioned at the top one filter membrane saved on described pvc pipe and reserves the length given according to design, so can regulate the entire length of described device neatly, and be easy to and the overlap joint of top supervisor, chimney filter；Bottom one saves described pvc pipe is provided with bottom.
Further, the pvc pipe described four-way left and right branch joint connected is provided with lid.
Further, described filter membrane is fixed on pvc pipe by nylon cable tie.
Further, the using method of a kind of vertical three-dimensional drainage arrangement reinforced for blowing-filling sludge, it is characterized in that, comprise the steps:
(1) building cofferdam, dig press mold ditch, blowing-filling sludge is to designed elevation；
(2) for making vertical three-dimensional drainage arrangement workmen's normal construction, laying ground floor woven bag, workmen stands in and is manually inserted vertical three-dimensional drainage arrangement on woven bag, and filter membrane exposes blowing-filling sludge layer more than upper surface 20cm, and is connected with supervisor, chimney filter；If standing in constructional difficulties on woven bag, pontoon can be used and plug vertical three-dimensional drainage arrangement；
(3) according to the position that design is given, monitoring instrument is installed；
(4) lay second layer woven bag, lay two-layer diaphragm seal, and mould is entered press mold ditch, vacuum pump evacuation is installed；
(5) owing to blowing-filling sludge intensity is more weak, the mode evacuation stepping up turn on pump rate, full-load run after some strength to be generated are adopted；
(6) in time being evacuated down to the degree of consolidation of design, stop evacuation, remove pumped vacuum systems, reclaim vertical three-dimensional drainage arrangement skeleton.
The beneficial effect that the present invention reaches:
1) by vacuum load effectively to transmission in mud, shorten drainage distance further, accelerate the consolidation of the soil body, reduction of erection time effectively；2) mode manually setting draining board is adopted, it is not necessary to laying sand bedding course in advance, especially in the area that sand source is in short supply, the method effect is fine；3) vertical drainage device can be reused, and reduces cost.
