Technical field
The present invention relates to a kind of floatation type surface water dewatering installation and method of in mud stockyard and hydraulic reclamation epeirogenetic place, using thereof of extracting surface area water; Be to be directed to the extremely low mud stockyard of bearing capacity and blast-filled ground especially under conventional drainage plant can't the situation of drainage construction and the dewatering installation of the floating extraction surface area water of design belongs to correlative technology fields such as geotechnical engineering and Environmental Engineering.
Background technology
In the training of river channel desilting engineering and the engineering of reclaiming land from the sea, all can run into the hydraulic reclamation solidification problem of the high-moisture percentage soil body.For hydraulic reclamation the place of high-moisture percentage mud, in short-term, can form one deck have certain thickness surperficial water layer, the soil body below the water layer is still keeping very high moisture content, or even a kind of semifluid form near original state; Under the situation of so surperficial water layer and rare weak soil layer, bearing capacity is extremely low, and condition or some small-sized boring mechanics of not possessing last people's construction all are difficult to get into the place, more need not carry big machinery.Carry out the project of further engineering and the expropriation of land engineering of second ploughing as early as possible for the land used of being eager; How to reduce the moisture content of high-moisture percentage mud in the stockyard apace; Improve the degree of consolidation, increasing bearing capacity is crucial problem, therefore needs to adopt artificial means to accelerate drainage procedure.Through field experience for many years; If after the ponding removing with the top layer, stockyard in very short time; The surface evaporation of exposing to the weather through after a while can form the thicker crust layer of one deck at the barged-in fill laminar surface, is being mingled with herbal rhizome residue; Make topsoil have certain apparent intensity, make follow-up artificial or light-duty drainage machinery to carry out drainage construction the soil body of stockyard deep inside.So be badly in need of developing a kind of at bearing capacity extremely low mud stockyard and blast-filled ground, conventional drainage plant can extract the dewatering installation of surface area water under can't the situation of drainage construction simultaneously, to solve problem actual in the engineering.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention proposes a kind of floatation type surface water dewatering installation and method of in mud stockyard and hydraulic reclamation epeirogenetic place, using thereof of extracting surface area water, in order to solve the extremely low mud stockyard of bearing capacity and blast-filled ground simultaneously conventional drainage plant can't the situation of drainage construction under the engineering roadblock of extraction surface area water.
Technical scheme: for solving the problems of the technologies described above, a kind of floatation type surface water dewatering installation of the present invention comprises floating circle and trap drainage body; Described floating circle center is provided with cylindrical cavities, and floating circle is provided with the mooring circle, and described trap drainage body is the cylindrical frame structure; The external diameter of trap drainage body equates with the cylindrical cavities radius; As support, trap drainage body bottom is provided with permeable filtering material layer with the plastics french drain in trap drainage body inside, and the outside of trap drainage body except that the bottom surface covers sealant; Trap drainage body top is provided with soft vacuum pipe, and described soft vacuum pipe is connected trap drainage body inside with vacuum source.
As preferably, described floating circle is the flexible circle body that light waterproof material is processed.
A kind of suction method based on floatation type surface water dewatering installation may further comprise the steps:
1) the trap drainage body is pressed into the cylindrical cavities in the floating circle, makes that the cylinder bottom surface of trap drainage body and floating circle bottom surface are in the same plane, soft vacuum pipe is connected the top of trap drainage body, and seal;
2) two stay cords are lain on the mooring circle of floating circle,, mounted floatation type surface water row filter body device is fixed on surface, the mud stockyard water surface that needs extraction through pulling two stay cords;
3) open vacuum source, pull of vacuum is passed in the columned trap drainage body through soft vacuum pipe, surface water is progressively extracted;
4) after the surface water of a certain position, mud stockyard is taken out to the greatest extent, the pulling stay cord is repositioned onto the position that the next one is treated draining with floatation type surface water row filter body device;
5) repeating step 2) ~ 4), progressively the surface water of mud stockyard or blast-filled ground is got rid of.
Beneficial effect: the present invention is used in the mud place or blast-filled ground extracts the floatation type surface water dewatering installation and the method thereof of surface area water, can overcome the problem that under conventional drainage plant can't the situation of drainage construction, is difficult to extract surface area water at the extremely low mud stockyard of bearing capacity or blast-filled ground; And this floatation type surface water row filter body structure lightweight, portable, can under weak soil or the hypodynamic situation of mud place surface bears, use; Adopt modularized design, can carry out installing/dismounting easily, safeguard simple and easyly, expense is low; Adopt floating mode, move and control the operating position of water discharging body through stay cord.Floatation type surface water row filter body structure equipment is simple, lightweight, and easy and simple to handle, efficient is high, and the draining cost is low.
