Abstract

The utility model relates to a plate for water drainage and ground strengthening. The utility model comprises a plastic strip-shaped core plate which is provided with water drainage grooves; filtering film cloth is arranged outside the core plate, and the water drainage grooves are arranged on both surfaces of the plastic core plate which is wrapped by the filtering film cloth; the filtering film cloth and the plastic core plate are overlapped with each other inside and outside a single side, and adhesive agent is coated between two overlapped layers to form an annular sealing cross section. The utility model has the characteristics of good sealing, uniform wrap, high water filtering rate, large water drainage quantity, ensured engineering quality, etc. No through hole is remained in the manufacture.

Description

The ground stabilization band drain

The utility model relates to the adrainage material of ground stabilization, is mainly used in the reinforcing draining of the high soft foundation of water content such as tidal land, husky film.

With plastics (as polyethylene etc.) is that raw material is made central layer, be that raw material is made filter membrane cloth with terylene, polypropylene fibre or vinylon fibre etc. again, filter membrane cloth is wrapped in the central layer outside makes band drain, band drain inserts underground, making underground water enter the central layer rhone by filter membrane and discharge, is a kind of new material that is applicable to that reinforced soft soil ground is handled.Existing above-mentioned band drain is by suture central layer and filter membrane cloth to be made together, be the filter membrane cloth that suture passes central layer and parcel outside, thereby produce following defective: the one, underground mud enters quilted plastic panel by the pinprick of sewing up, stop up the drainage channel of quilted plastic panel, influence band drain at underground drainage effect, reduced the displacement of actual demands of engineering; The 2nd, in sewing up making, the manually-operated sewing machine, be difficult to accomplish the interior straight line stitching of a groove of plastic draining board, and pinprick sample different in size, the degree of tightness of parcel is inconsistent, composite construction to band drain does not reach stay-in-grade requirement, and therefore, applying of this technology will be had a strong impact on.

The purpose of this utility model provides a kind of avoiding and sews up, and makes plate core and filter membrane cloth injury-free, guarantees the ground stabilization band drain of drainage effect.

The technical scheme of the utility model ground stabilization band drain is: the banded central layer that plastics are made, rhone is arranged on the central layer, there is filter membrane cloth the outside of central layer, it is characterized in that rhone is on the two sides of quilted plastic panel, filter membrane cloth ring bag central layer, and overlapping inside and outside a side, coating adhesive forms ring-type involution cross section between two overlapping layers.

Ground stabilization band drain of the present utility model, its so-called filter membrane cloth is nonwoven.

The utility model is a kind of reinforced soft soil ground band drain, particularly to the improvement of central layer and filter membrane cloth fit structure, makes central layer and filter membrane cloth injury-free, does not have artificial through hole with the external world, avoids the intrusion of fine earth particle, and every rhone is unimpeded on the central layer.Therefore, compared with the prior art, it is good to have an involution, and parcel degree of tightness unanimity is not made and not stayed through hole, the filtration rate height, and displacement is big, guarantees workmanship, obtains beyond thought effect.

Fig. 1 is the utility model ground stabilization band drain cross-sectional structure schematic diagram;

Fig. 2 is the utility model ground stabilization band drain filter membrane cloth cover and rhone schematic diagram.

Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.

The utility model relates to the construction material band drain, makes banded central layer 1 by plastic raw materials, and there are uniform muscle 2 and rhone 5 in the two sides of central layer, the coated outside filter membrane cloth 4 of whole piece central layer 1, and filter membrane cloth is overlapping by two-layer bound edge, middle coating adhesive 3.So-called bonding agent is a kind of chemical glue, and chemical glue is expressed on the filter membrane cloth 4 by extruder by heating the back, and is bonding through bonder again.Bonder needs temperature automatically controlled, outside the automatic speed regulation, also draw-gear must be arranged.In order to guarantee the stability of adhesion process,, the Wrap device of filter membrane cloth and quilted plastic panel is installed at the front end of bonding packing machine.To the requirement of bonding agent, not only bond strength is good, and will be fit to be embedded in the needs of underground long term, has the performance of good anti-aging, anti-soda acid.

Claims (2)

1, ground stabilization band drain, the banded central layer that plastics are made, rhone is arranged on the central layer, there is filter membrane cloth the outside of central layer, it is characterized in that rhone (5) is on the two sides of quilted plastic panel (1), filter membrane cloth (4) ring bag central layer (1), and overlapping inside and outside a side, and coating adhesive between two overlapping layers (3) forms ring-type involution cross section.

2, ground stabilization band drain as claimed in claim 1 is characterized in that so-called filter membrane cloth (4) is nonwoven.
