Drawings

FIG. 1 is a schematic structural view of a slope-shaped diversion drainage plate according to an embodiment of the present invention;

fig. 2 is a structural side view of the slope-shaped diversion drainage plate of the embodiment of the invention.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention, the following description will explain embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.

As shown in fig. 1-2, in the slope-shaped diversion and drainage plate of the embodiment of the present invention, the bottom of the drainage plate is a horizontal plane so as to be matched with the ground; the top of the drainage plate is provided with a drainage surface 1, the drainage surface 1 has a preset gradient, so that water can be drained conveniently, the gradient is 3-10 degrees, and the specific gradient can be designed according to practical application occasions; the drain bar 1's drainage face has a plurality of rows of water drainage tank, and every row of water drainage tank includes the several water drainage tank 10 that distributes in proper order along the slope direction, and the water drainage tank 10 that is located same row communicates in proper order and constitutes drainage channel, and the water accessible drainage channel of seepage to water drainage tank discharges.

Wherein, in the drainage grooves in the same row, the adjacent drainage grooves are communicated through a channel 12 along the gradient direction; that is, the channels between the drainage grooves in the same row are positioned on the same slope straight line, so that the water in the drainage grooves is discharged without resistance. In addition, the size of the opening of the drainage groove is larger than that of the bottom of the drainage groove, so that the structural strength of the drainage plate is improved.

Be equipped with reverse supporting seat 11 in every water drainage tank 10, supporting seat 11 protrusion is on water drainage tank 10's opening for the supporting seat can bear weight. All the supporting seats 11 have the same height, so that the upper plane and the lower plane of the drainage plate are kept horizontal. Wherein, the supporting seat 11 is the frustum structure, and the supporting seat 11 is hollow structure, compromises the structural strength and the material cost of drain bar.

In addition, the bottom of the drainage groove at the lowest slope is flush with the drainage surface of the drainage plate connected with the drainage groove, so that water in the drainage grooves in the same row can be drained sequentially and smoothly.

The utility model discloses drain bar integrated into one piece, the material can be ABS plastics, resin or polycarbonate plate body material.

In order to isolate the bearing objects (such as soil, gravel and the like) on the drainage plate, a filter layer is arranged on the drainage surface of the drainage plate, the filter layer is made of geotextile or non-woven fabric, and is fully paved and covered above the drainage plate to isolate the soil, so that water flow in the soil can permeate into the drainage plate below, and the soil cannot permeate to avoid blocking the drainage channel of the drainage plate.

The utility model discloses slope shape water conservancy diversion drain bar through the reverse support of the supporting seat towards recessed water drainage tank and epirelief, under the prerequisite that two planes keep the horizontal plane about guaranteeing the drain bar, realized that the percolating water moves towards according to predetermined slope and excretes fast, current drain bar compares, on the draining plate plane bottom plate is always oozed to the percolating water, consequently the bottom plate if there is the slope, then drainage effect is good.

In present drain bar main application field and scene, under a plurality of underground space and the planting roofing top does not have the slope or has the condition of hollow concave unevenness, rivers trend is more chaotic and sluggish, and easy ponding (ooze the water and be detained) causes the seepage hidden danger very easily, adopts the utility model discloses above-mentioned problem can be solved to the slope shape water conservancy diversion drain bar of embodiment.

The utility model discloses slope shape water conservancy diversion drain bar mainly uses similar scenes such as planting roofing, underground space roof, underground garage roof, ground road surface, square, and from top road surface or planting layer infiltration's rainwater or irrigation water ooze the back on the drain bar naturally, because the existence of drain bar slope shape bottom surface, the trend of rivers can artificial control management, and the rivers speed of excretion is higher than planar natural drainage far away, has eliminated the ponding hidden danger of the arbitrary unevenness position in plane moreover. Even if the slope exists, the compressive strength of the whole drainage plate plane is not influenced at all, and the bearing gravity centers of all bearing points are not changed, so that the compressive requirement in engineering construction is ensured; the pressure-resistant requirement is the basic guarantee that the product realizes the drainage function.

The utility model discloses slope shape water conservancy diversion drain bar passes through and oozes the collocation combination of calandria with T type or M type, can form effective confined drainage system, can ensure basically that the drain bar below (roof layer, underground space roof, waterproof layer) does not have the rivers that ooze and get into, has played perfect isolation, has thoroughly solved the seepage difficult problem that this type of building roof exists always.

The foregoing has been a detailed description of the preferred embodiments and principles of the present invention, and it will be apparent to those skilled in the art that variations may be made in the specific embodiments based on the concepts of the present invention, and such variations are considered as within the scope of the present invention.
