Abstract

The utility model relates to a pervious brick for rapidly permeable stopping pad, belonging to the field of building technology, in particular to a brick for being paved on the ground; the brick comprises a pervious brick body, and a pervious through hole is arranged in the middle of the pervious brick body; the brick is characterized in that: raised table edges are arranged at the lower part of the surrounding of the pervious brick body, a shallow groove is arranged in the middle section of the raised table edge, and four corners of the table edge of the pervious brick body form cutting angle with 45 degrees. The pervious brick has low manufacturing cost, and is convenient for being paved and is not easy to be loosed; the brick can lead all the rain water in heavy rain or torrential rain back to be seeped under ground, thereby being capable of not leading the rain water in the heavy rain or the torrential rain to be accumulated in parking lot. The brick is particularly suitable for the parking lot with high utilization ratio, can better beautify the environment and reduce maintaining cost.

Description

The permeable brick of stopping pad of fast permeable speed

Technical field:

The utility model relates to a kind of permeable brick of stopping pad of fast permeable speed, and it belongs to technical field of buildings, the brick that lay on particularly a kind of ground.

Background technology:

Existing stopping pad is the grass planting brick with permeable brick.Use the grass planting brick all to exist following shortcoming at stopping pad:

1) most grass planting bricks for preventing the loosening cement mortar seat slurry making that needs to adopt, in fact can not play the effect that rainwater bleeds back when laying.Need not sit the higher difficult popularization of grass planting brick cost of slurry making individually, and after having used a period of time, along with the growth on lawn, penetrating passage seals gradually, the permeability of soil variation, the rainwater of moderate rain or heavy rain forms runoff because of not infiltrating the earth rapidly.

2) in the higher parking lot of utilization rate, because automobile makes the grass of parking spot to survive to the blocking of sunlight, survival rate generally is no more than 10%.Survive this part in, its growing way is also quite withered.So use the grass planting brick in the higher parking lot of utilization rate, bleed back and beautify the environment for rainwater and do not have substantial meaning.

Summary of the invention:

The purpose of this utility model is to provide a kind of cheap, easy making, is difficult for the permeable brick of stopping pad loosening, that whole rainwater of heavy or torrential rain can be bled back underground fast permeable speed.

The purpose of this utility model is achieved in that

The permeable brick of a kind of stopping pad of fast permeable speed, it comprises permeable brick brick body, is provided with permeable through hole in the middle of the described permeable brick brick body, the bottom is provided with the edge of table of projection around described permeable brick brick body; The edge of table stage casing of described projection is provided with shallow grooves; Four jiaos of the edge of table of described permeable brick brick body are 45 degree corner cuts.

The permeable through hole of described permeable brick brick body is rectangle or square.

The permeable through hole of described permeable brick brick body is circular or oval.

Described permeable brick brick body is square brick body or straight brick body.

The utility model is cheap, making is convenient and it is loosening to be difficult for; And whole rainwater of heavy or torrential rain can be bled back undergroundly, can not cause the parking lot because heavy rain or heavy rain and ponding.The utility model is specially adapted to the higher parking lot of utilization rate, can beautify the environment, reduce maintenance cost preferably.

The specific embodiment:

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model is further detailed:

Embodiment 1:

As shown in accompanying drawing 1, Fig. 2, Fig. 3.

In the present embodiment, the utility model comprises permeable brick brick body 1, is provided with permeable through hole 4 in the middle of the described permeable brick brick body 1, and the bottom is provided with the edge of table 2 of projection around described permeable brick brick body 1; Edge of table 2 stage casings of described projection are provided with shallow grooves 3; Four jiaos of the edge of table 2 of described permeable brick brick body 1 are 45 degree corner cuts 7.When spreading the utility model on the ground, the node at four angles of four adjacent permeable bricks has constituted foursquare limbers 6 like this; The permeable seam 5 that the edge edge joint position of adjacent permeable brick has formed grooved seam 8 and has been combined into by shallow grooves 3.The permeable through hole of described permeable brick brick body 1 is rectangle or square.In the present embodiment, the permeable through hole of described permeable brick brick body 1 is a square.Described permeable brick brick body 1 is square brick body or straight brick body.Permeable brick brick body 1 is a square in the present embodiment.

In order to realize the purpose of fast permeable speed of the present utility model and Seepage water, the utility model need use following method and step to lay:

A: at first the retaining crushed rock base course should be laid by stopping pad basic unit, and according to the different retaining rates of determining its retaining crushed rock base course of kind of rubble, the retaining rate is calculated by 30～40%, and the macadam compacting is offseted;

B: described permeable brick is tiled in the surface of retaining crushed rock base course, and the node of laying four angles of four adjacent permeable bricks of back has constituted foursquare limbers 6; The permeable seam 5 that the edge edge joint position of adjacent permeable brick has formed grooved seam 8 and has been combined into by shallow grooves 3;

C: cement injection mortar in the square limbers 6 at four jiaos of node places that join of described permeable brick, with four angles of permeable brick bottom surface with and the macadam of below be bonded as one;

D: in described grooved seam 8, fill rubble or pea gravel concreten; In the permeable through hole 4 at permeable brick middle part, fill rubble or cobble again.In the present embodiment, select to fill rubble.

Described permeable brick brick body 1 is a concrete for making, and described concrete crushing strength is not less than 25MPa.

Operating principle of the present utility model is as follows:

Its four angles because described permeable brick only bonds when laying can not resemble common permeable brick and sit slurry and block penetrating passage laying.And permeable brick middle part be provided with a permeable through hole that fills up rubble again, rainwater can flow directly into the rubble aquifer and stores in macadam along this permeable through hole, then slowly in depth down.As long as the thickness of macadam is reasonable, just can store whole rainwater of short-time storm.Usually the retaining rate of macadam can be calculated by 40%.

For the not high parking lot of utilization rate, the square through-hole cement injection mortar at the node place that can join to four jiaos of permeable brick, filling planting soil in grooved seam and rectangular through-hole then, at this moment this permeable brick just can be used as a kind of good grass planting brick use.

Embodiment 2:

As shown in accompanying drawing 4 and Fig. 5.The permeable through hole of permeable brick brick body 1 of the present utility model also can be made becomes circle or ellipse.In the present embodiment, permeable through hole 9 is designed to circle.

During laying, in described grooved seam, lay reinforcing bar earlier, recharge pea gravel concreten.The compressive strength of the pea gravel concreten that adopts during laying should be not less than 20MPa, and the reinforcing bar that is adopted is preferably 5～8mm cold-drawn Ribbed Bar.

Identical among other structure divisions in the present embodiment and laying method and the embodiment 1.
