Abstract

The utility model discloses a composite draining and air pumping electrode tube which is formed by an inner tube provided with a plurality of pores on the tube wall and enwrapped in a percolation layer, and an unsaturated zone with a rugged surface is arranged between the inner tube and the percolation layer. The composite draining and air pumping electrode tube is integrated with draining, subpressure transfer and an electrode into a hole, particularly realizes effective subpressure transfer, has simple operation and low cost, and can be used in a processing method of a large-area soft base.

Description

Composite water drainage air-exhausting electrode tube

Technical field

The utility model relates to the clad pipe that a kind of Ground Treatment is used, and especially relates to a kind of composite, water-drain, bleeds, the electric osmose pipe.

Background technology

At present, in large-area soft foundation consolidation process worker method, it is 200710050724.7 patent that the used clad pipe of technology such as vacuum preloading, electric osmose and composite electroosmosis and vacuum preloading has application number, this invention is mainly wrapped up in the single or multiple lift filtration beds outward by the draining exhaust tube and is formed, vacuum is drawn water and electroosmosis electrode acts on simultaneously, but it is difficult to form negative pressure space with surrounding soil, can't realize the vacuum preloading function simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of composite water drainage air-exhausting electrode tube is provided, and its collection draining, negative pressure transmission and electrode are one, not only draining, energising, key can also realize effective negative pressure transmission, and simple to operate, with low cost.

The purpose of this utility model is achieved in that

A kind of composite, water-drain, bleed, electrode tube is to wrap up in the only permeable not filter layer of saturating silt outward by the interior pipe that tube wall is distributed with a lot of apertures, between interior pipe and filter layer unsaturated zone arranged, it is the packed layer of surface irregularity.

Compared with the prior art, the utility model has following advantage:

1, because of between the utility model filter layer and the interior pipe pore space being arranged, makes the outer wall universe of clad pipe all can transmit vacuum and negative pressure, change the conventional composite pipe and can only realize that vacuum draws water and the electroosmosis electrode effect, and can not realize the limitation of vacuum preloading.

2, make simply.

3, fully based on current material, it is very extensive to draw materials.

Description of drawings

Fig. 1 is the utility model composite, water-drain, bleed, the vertical section schematic diagram of electrode tube.

Fig. 2 is the utility model composite, water-drain, bleed, the electrode tube schematic cross section.

Among the figure: interior pipe 1, interior pipe aperture 2, unsaturated zone 3, filter layer 4.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1, the 2nd, structural representation of the present utility model, it be by the interior pipe 1 that is distributed with many apertures 2 on the tube wall be wrapped with only permeable not saturating silt filter layer 4, between interior pipe and filter layer, have the rough packed layer of surfaces externally and internally to make unsaturated zone 3 to constitute.

Embodiment

The experimental area, Zhejiang, composite vacuum prepressing and electric osmose reinforcing soft ground are handled 6 meters of the degree of depth.

1, smooth place.

2, with wide 1256cm, the plastic draining board of long 6.5m is made unsaturated zone, is wrapped in bore 40cm, is distributed with outside the coating steel pipe of many apertures on the long 6.5m tube wall, then filter cloth is wrapped tightly in being rolled on the columned plastic draining board, promptly made clad pipe of the present utility model.

3,, the NEW TYPE OF COMPOSITE pipe is put into the hole, from the vacuum pump that connects suitable for reading of clad pipe at the desired location preexisting hole.

4, start vacuum pump, begin to vacuumize.

5, after 10 days, breakdown NEW TYPE OF COMPOSITE pipe, the vacuum preloading effect is better than the clad pipe of prior art, and handles evenly.

Claims

1. a composite water drainage air-exhausting electrode tube interior pipe that is distributed with a lot of apertures by tube wall is wrapped up in the only permeable not filter layer of saturating silt outward and is formed, and it is characterized in that between interior pipe and filter layer unsaturated zone being arranged, and unsaturated zone is the packed layer of surface irregularity.
