Description

A kind of vertical three-dimensional drainage arrangement reinforced for blowing-filling sludge and application method
Technical field
The present invention relates to a kind of vertical three-dimensional drainage arrangement reinforced for blowing-filling sludge and application method, belongs to hydraulic reclamation silt The reinforcement technique field of mud.
Background technology
With China coast rapid development of economy, construction land day is becoming tight, and coastal, riparian area navigation channel cleaning Caused mud can not usually be handled, and based on this, the reclamation by pumping filling of large area turns into the important method for solving problem above.So And the mud of hydraulic reclamation has moisture content height recently(200% can usually be reached), the features such as void ratio is big, low intensity, if conducting oneself with dignity Consolidation forms certain intensity under stress, then needs the time of 1 to 2 years, this will have a strong impact on the duration, it is therefore necessary to which it is carried out Processing.
The method of generally use is vacuum preloading, the processing for the place after hydraulic reclamation, is substantially the height of use The method that position vacuumizes, vacuum load can not be efficiently transferred in mud.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided one kind is used for blowing-filling sludge and reinforced Vertical three-dimensional drainage arrangement and application method.
In order to solve the above technical problems, 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, the pvc pipe is provided with hole, and the filter membrane is enclosed on pvc pipe, will be some The individual pvc pipe for being cased with filter membrane is connected to design length by the major joint up and down of four-way several described, the four-way Left and right branch joint also connects the pvc pipe for being cased with filter membrane.
Further, the angle of the four-way is 45 degree.
Further, the pvc pipe both ends are provided with joint and are used to connect four-way.
Further, the length given according to design is reserved positioned at the filter membrane topmost on a section pvc pipe, so both The entire length of described device can be neatly adjusted, and be easy to the overlap joint with top supervisor, chimney filter;The section PVC of bottom one Pipe is provided with bottom.
Further, the pvc pipe connected on described four-way or so branch joint is provided with lid.
Further, the filter membrane is fixed on pvc pipe by nylon cable tie.
Further, a kind of application method for the vertical three-dimensional drainage arrangement reinforced for blowing-filling sludge, it is characterized in that, bag Include following steps:
(1)Cofferdam is built, digs press mold ditch, blowing-filling sludge to designed elevation;
(2)To make vertical three-dimensional drainage arrangement workmen normal construction, first layer woven bag is laid, workmen station exists Vertical three-dimensional drainage arrangement is manually inserted on woven bag, filter membrane exposes more than blowing-filling sludge layer upper surface 20cm, and with being responsible for, filtering Pipe is connected;If standing the constructional difficulties on woven bag, pontoon can be borrowed and plug vertical three-dimensional drainage arrangement;
(3)Monitoring instrument is installed according to design given position;
(4)Second layer woven bag is laid, lays two layers of diaphragm seal, and mould is entered into press mold ditch, installation vavuum pump vacuumizes;
(5)Because blowing-filling sludge intensity is weaker, vacuumized by the way of turn on pump rate is stepped up, some strength to be generated Full-load run afterwards;
(6)When the degree of consolidation of design is evacuated down to, stop vacuumizing, remove pumped vacuum systems, reclaim vertical vertical Body drainage arrangement skeleton.
The beneficial effect that the present invention is reached:
1)Vacuum load is effectively transmitted into mud, further shortens drainage distance, accelerates the consolidation of the soil body, Effectively shorten the duration;2)By the way of drain bar is manually set, it is not necessary to sand bedding course is laid in advance, it is especially in short supply in sand source Area, the method effect is fine;3)Vertical drainage device can be reused, and reduce cost.
