Description

Road rainwater drainage water permeable brick for collapsible loess area

Technical Field

The utility model belongs to the technical field of building engineering, a road rainwater drainage brick that permeates water for collapsible loess area is related to.

Background

Collapsible loess is a soil of special property, and its soil property is more even, the structure is loose, when not soaking by water, and general intensity is higher, when soaking the back by water under certain pressure, the soil structure can destroy rapidly, produces great additional and sinks, and intensity reduces rapidly, leads to the ground collapsible easily, produces the harm to the building. Although the permeability of the urban ground is increased to a certain extent by the existing water permeable bricks, the problem that the impermeability is difficult to ensure exists, so that a road brick which has stronger impermeability and can quickly drain water is urgently needed when urban construction is carried out in collapsible loess areas.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the problem that prior art exists, a road rainwater drainage brick that permeates water for collapsible loess area is provided, solved present brick that permeates water impervious ability weak, the not fast problem of drainage speed inadequately.

Therefore, the utility model adopts the following technical proposal:

the utility model provides a road rainwater drainage brick that permeates water for collapsible loess area, includes the brick body, its characterized in that, the brick body is squarely, and its week side is equipped with the cross section and is trapezoidal water conservancy diversion border, the water conservancy diversion border has certain contained angle with the brick face, the brick body is equipped with permeable bed, drainage layer and impervious layer by last under to in proper order, the permeable bed is the mesh board, the drainage layer is equipped with the through-hole of a plurality of vertical ranges, the impervious bed is the dislocation set with the drainage layer, and its position department that corresponds the through-hole is equipped with the catch basin.

Furthermore, a filter screen is arranged between the permeable layer and the drainage layer.

Furthermore, the flow guide edges of the four bricks enclose a flow guide hole, and a water storage tank is also arranged at the position of the impervious layer corresponding to the flow guide hole.

Further, the inner wall of the through hole is provided with a rubber layer.

Furthermore, the included angle between the flow guide edge and the brick surface is 5-10 degrees.

Further, the permeation resistant layer is made of an ABS material.

The beneficial effects of the utility model reside in that:

the utility model discloses the brick body has continuous space, has stronger infiltration capacity, can effectively reduce the earth's surface path flow, and the guide rainwater infiltrates down fast, avoids road ponding, and with anti-seepage layer and drainage layer dislocation set simultaneously, the brick of avoiding permeating water continues to infiltrate down to the soil body after the rainwater infiltration concatenation gap when using, leads to the condition that the soil body wet falls.

fig. 2 is a schematic top view of the present invention.

In the figure, 1-brick body, 2-flow guiding edge, 3-flow guiding hole, 4-permeable layer, 5-flow guiding layer, 51-through hole, 6-anti-seepage layer, 61-water storage tank and 7-filter screen.

Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings and implementation methods.

As shown in fig. 1 and 2, the road rainwater drainage permeable brick for the collapsible loess area comprises a brick body 1, wherein the brick body 1 is square, a flow guide edge 2 with a trapezoidal cross section is arranged on the periphery of the brick body 1, and an included angle between the flow guide edge 2 and the brick surface is 5 degrees, so that rainwater can slide off in time; after the four bricks 1 are spliced, the respective flow guide edges 2 of the four bricks enclose to form a flow guide hole 3, and the flow guide hole 3 is used for timely discharging rainwater collected in the flow guide edges 2.

The brick body 1 is sequentially provided with a permeable layer 4, a drainage layer 5 and an impervious layer 6 from top to bottom, the permeable layer 4 is a mesh plate, meshes of the permeable layer are strip-shaped, and compared with a round hole mesh plate, the brick has the advantages that the permeable area is larger, the drainage speed is higher, a filter screen 7 is arranged between the permeable layer 4 and the drainage layer 5, the filter screen 7 is used for filtering impurities, preventing fallen leaves, silt and the like from blocking a drainage pipeline, and removing the impurities on the surface of the filter screen 7 in time in daily road cleaning; the drainage layer 2 is formed by mixing high-strength cement and a cement polymer reinforcing agent with polypropylene fibers and then pressing after stirring, and mainly functions as drainage and support, the drainage layer 5 is provided with a plurality of vertically arranged through holes 51, the inner walls of the through holes 51 are provided with rubber layers, and the rubber layers are beneficial to the water drops to slide down as soon as possible, so that the situation that the hole walls absorb water to cause corrosion is avoided; the positions of the anti-seepage layer 6 corresponding to the through holes 51 and the diversion holes 3 are provided with water equalizing storage tanks 61, and the water equalizing storage tanks 61 are connected with municipal drainage pipelines; anti-seepage layer 6 is dislocation set with drainage layer 5, its advantage lies in, after the brick body 1 arranges and lays, the rainwater of infiltration can directly drip to the catch basin 61 in its concatenation gap, avoid the rainwater to see through concatenation gap infiltration soil, it sinks to lead to the ground to absorb water easily to make up for a long time, preferentially, anti-seepage layer 6 is made by the ABS material, the ABS material not only has sufficient intensity, corrosion-resistant and waterproof advantage has simultaneously, compare traditional concrete material, ABS material advantage is more outstanding, the while quality is lighter, can make the whole weight of brick body 1 alleviate, easily transport.

The utility model discloses in the use, in some rainwater, ponding etc. flow into water conservancy diversion hole 3 along with water conservancy diversion border 2, another part will flow into the through-hole 51 of drainage layer 5 from the permeable bed in, then, the water of water conservancy diversion hole 3 and through-hole 51 will converge into catch basin 61 together, because catch basin 61 communicates with each other with municipal drainage line, so the rainwater can be discharged rapidly, in addition, the utility model discloses the brick body 1 still has the advantage that rupture strength is high, weight is lighter, and the suitability is strong, easily promotes.
