Abstract

The invention discloses a combined drain board which comprises a filtering layer, a drain layer and an insulation layer, wherein the drain layer is coated with the filtering layer to form a drain board core arranged on the insulation layer. The combined drain board is characterized in that the drain layer comprises a plurality of belt-shaped drain bands which are bent continuously to form square wave shapes and provided with smooth upper contact surfaces and lower contact surfaces, the upper contact surfaces and the lower contact surfaces have different directions, pits are formed in the corresponding positions of the lower contact surfaces on the drain bands, bosses are arranged at the corresponding positions of the upper contact surfaces on the drain bands, the drain bands are arranged side by side, the pits in the drain bands align to each other, and the lower contact surfaces and the upper contact surfaces are bonded with the filtering layer after the drain layer is coated with the drain layer. Drain performance is reinforced while the drain board has high strength, and better drain effect is achieved.

Description

Combined water-drainage plate

Technical field

The present invention relates to a kind of band drain.

Background technology

Band drain is laid between basic unit and construction layer in civil construction engineering, the moisture that construction layer infiltration is come puts together and is discharged in specific drainage pipe, guarantee that the water content of basic unit and construction layer, in suitable scope, has guaranteed the intensity of basic unit and construction layer.Current band drain consists of drainage blanket and the filtration beds that is wrapped in outside drainage blanket, and wherein, drainage blanket is the plate object on a plate face with boss, and the gap between each boss has formed the drainage channel for water flow.But the boss on its drainage blanket of this band drain takies a part of space, thereby reduced the space of drainage channel, if and by the volume-diminished of boss, not only can reduce the overall space of drainage blanket and reduce the space of drainage channel, and can reduce the weight capacity of boss, affect the intensity of band drain.And because drainage blanket is the plate object of a monoblock, therefore comparatively inconvenient in the laying meeting in some non-flat front.

Summary of the invention

For the deficiencies in the prior art, it is good and can be applicable to the combined water-drainage plate of different terrain that the problem to be solved in the present invention is to provide the high drainage effect of a kind of intensity.

For this reason, the present invention is in the following way: a kind of combined water-drainage plate, comprise drainage layer, drainage blanket and isolation layer, described drainage layer is wrapped in and on drainage blanket, forms band drain core and be placed on isolation layer, it is characterized in that: described drainage blanket comprises some banded drainage belts that are, described drainage belt continuously bending is square-wave-shaped and has towards the opposite and smooth upper contact surface and lower contact surface, described lower contact surface corresponding position on drainage belt is rendered as a pit, described upper contact surface corresponding position on drainage belt is rendered as a boss, some described drainage belts are arranged side by side and the pit on it aligns mutually, described upper contact surface and lower contact surface after drainage layer is wrapped on drainage blanket and drainage layer bonding.

Between adjacent described drainage belt, there is gap.

The width in described gap is not more than the width of drainage belt.

The both sides of described band drain core on drainage belt width are provided with U-shaped water collection sheet.

On described isolation layer soffit, be attached with pressure-sensitive adhesive layer.

Described drainage layer is nonwoven.

In the present invention, drainage belt be arranged side by side and the pit on it aligned with each other, namely boss is also aligned with each other, pit on all drainage belts can be for the drainage channel of water flow one of rear formation aligned with each other, same, boss has also formed a drainage channel after aligned with each other, article two, drainage channel is side by side greatly improved the drainage space of moisture, and reach better drainage effect, and on drainage belt, the size specification of pit and boss is extremely easy to make a change, thereby can very easily to drainage space, adjust, and because upper contact surface and the lower contact surface of boss and pit present position has very smooth and larger contact area, therefore drainage belt has very high compressive property, thereby improved the bulk strength of band drain, and the band drain being comprised of drainage belt itself has necessarily can deformability, therefore can be applicable to how different working face.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is that the present invention is along the sectional view of drainage belt width;

Fig. 3 is the structural representation of drainage belt in the present invention.

The specific embodiment

With reference to Fig. 1, Fig. 2, shown in Fig. 3, this combined water-drainage plate, comprise drainage layer 2, drainage blanket and isolation layer 1, described drainage layer 2 is wrapped in and on drainage blanket, forms band drain core and be placed on isolation layer 1, described drainage blanket comprises some banded drainage belts 3 that are, described drainage belt 3 continuously bending is square-wave-shaped and has towards the opposite and smooth upper contact surface 6 and lower contact surface 7, described lower contact surface 7 corresponding position on drainage belt 3 is rendered as a pit 8, described upper contact surface 6 corresponding position on drainage belt 3 is rendered as a boss 5, some described drainage belts 3 are arranged side by side and the pit on it 8 aligns mutually, described upper contact surface 6 and lower contact surface 7 after drainage layer 2 is wrapped on drainage blanket and drainage layer 2 bonding, between adjacent described drainage belt 3, there is gap, the width in described gap is not more than the width of drainage belt 3, such gap is arranged under the prerequisite that does not affect band drain drainage performance, reduced the laying density of drainage belt 3, also make to have between drainage belt 3 larger space that can deformation simultaneously, the both sides of described band drain core on drainage belt 3 widths are provided with U-shaped water collection sheet 4, on described isolation layer 1 soffit, be attached with pressure-sensitive adhesive layer 9, described drainage layer 2 is nonwoven.After this band drain has been laid, one jiao of U-shaped water collection sheet 4 towards gutter, the moisture of coming from upper strata infiltration enters between drainage belt 3 seeing through nonwoven drainage layer 2, pit 8 on all adjacent drainage channel bands 3 and boss 5 have formed two drainage channels after aligned with each other, moisture flows to U-shaped water collection sheet 4 along these two drainage channels, and collecting and finally flow in gutter by U-shaped water collection sheet 4 places, realize the function of draining.This band drain is laid when such as inclined slope once special, due between drainage belt 3, be flexibly connect and tool gapped, therefore band drain integral body has certain deformability, thereby can be applicable to better the special circumstances such as working face, and the pressure-sensitive adhesive layer 9 on isolation layer 1 soffit can strengthen grabbing of band drain and the laying construction face degree of making a concerted effort, band drain is laid in working face more securely.
