Abstract

The present invention discloses an environmental protection and water permeable brick for outdoor use, which can be laid on the ground of the cities to solve the groundwater drawdown of cities. The present invention comprises a brick body, wherein a plurality of through holes arranged in parallel and used for downwards permeating rain are arranged between the upper surface and the bottom face of the brick body. One improvement is that the through holes are taper holes with small upper parts and big lower parts, the structure can prevent the fillers in the holes from being compressed so as to facilitate the permeating of rain and the growth of plant in cities with good ventilating effect; the holes can be filled with soil to plant grass to beautify the environment and can also not be filled with soil, and the holes can naturally adsorb the dirt on the earth surface. The side wall of the brick body can also be provided with a tenon locking mechanism composed of a lug and a groove which are matched with each other; an embedded connection type structure is formed between brick bodies when the brick bodies are inlaid, and the embedded connection type structure is suitable for athletic grounds and training fields. The other improvement is that the side wall of the brick body is provided with a groove and the corners are provided with notches so as to form grouting holes; the brick has stable structure after being grouted, and is suitable for vehicle passing road surfaces and the side slopes of the railways and highways, such as parking lots, squares, etc.

Description

Use permeable environmental protection floor tile in the open

Technical field

The present invention relates to a kind of prefabricated floor tile that is used to lay open-air ground, city.

Background technology

Urban groundwater over-extraction problem is a big environmental protection difficult problem at present, and the unresolved rainwater of urban sewerage and drainage system replenishes phreatic problem.Open-air activity place, city of the prior art, its ground generally adopt the sclerosis measure to handle the face of land, have stoped the infiltration of rainwater, and rainwater can only enter sewer by the drainage system collection and enter the river course, and can not permeate the ground enters underground water storage layer.This open-air ground rainy day ponding, fine airborne dust, the aqueous vapor of having blocked the above and below ground exchanges, and has not only influenced the health of urban vegetation, has also aggravated urban heat land effect.Existing a kind of land use for greening brick, its brick body central authorities are provided with four kind grass holes, after floor tile is completed, can adorn native grass planting in the hole, this brick has certain following effect of oozing rainwater, but its perforate is bigger, the influence walking can only be local use the in the greenbelt zone on sidewalk, in addition, because its intensity is relatively poor, can not make the bus or train route face.Publication number is that the Chinese patent of CN2410321Y discloses a kind of pavior brick, is distributed with the aperture of up/down perforation on the brick body, and a kind of up-small and down-big infiltration hole scheme is wherein arranged, and not only can ooze rainwater down but also can prevent that earth from falling into the obstruction aperture.There is the unsteady problem in position between the brick body in this pavior brick.

Summary of the invention

The problem to be solved in the present invention be to provide a kind of be convenient to ooze under the surface water have a water-permeable and air permeable function use permeable environmental protection floor tile in the open.

The present invention adopts following technical scheme, comprise the brick body, be provided with several through holes that is used to seep water arranged side by side between the upper surface of described brick body and the bottom surface, described through hole is a bellmouth, described bellmouth aperture in brick body upper surface place is less, and the following aperture of bottom surface is bigger, and the peripheral side wall middle part of described brick body is provided with the groove that along continuous straight runs extends, the bight of described brick body upper surface is provided with small gap, grout hole of the adjacent small gap of adjacent bricks body one-tenth capable of being combined when paving ground.The brick body mat formation smooth after, inject cement paste from grout hole, cement paste enters the groove around the brick body sidewall, dry and hard back forms the locked mechanism locking position of will mating formation.

Adopt the present invention to have following advantage:

1, the through hole of brick body helps infiltering under the surface water into underground water storage layer rise groundwater table, has also reduced flow path surface, has environment protecting.

2, owing to also have ventilatory effect, help the interchange of above and below ground water, gas, heat, can promote urban vegetation growth, alleviating urban heat island effect, improve the comfort level of urban residence.

In the through hole of brick body, can insert earth when 3, mating formation, but the grass planting or the weeds self-sow of leaving in the hole there is the effect of afforesting and beautifying environment, if the soil that do not filler in the hole also has the function of absorption face of land dirt.

4, the bellmouth structure can make the hole inner stuffing keep rarefaction, is beneficial to permeable and ventilative.

5, the structure that adopts sidewall notches and establish grout hole, construction grouting forms locked mechanism, its Stability Analysis of Structures.This structure is suitable for parking lot, square and waited ground, parking lot and dykes and dams, railway, slope of highway.Available rubble adds earth and does basic unit, puts into effect to spread with cement mortar and handle in the compacting back.

6, because the aperture, last aperture of brick body is less, can be controlled to below the 16mm, do not influence people's walking.

The specific embodiment

As Fig. 5, Fig. 6, shown in Figure 7, embodiments of the invention, comprise brick body 1, be provided with several through holes 2 arranged side by side mutually between the upper surface of described brick body 1 and the bottom surface, described through hole 2 is a bellmouth, described bellmouth aperture in brick body 1 upper surface place is less, the following aperture of bottom surface is bigger, the peripheral side wall middle part of described brick body 1 is provided with the groove 8 that along continuous straight runs extends, the bight of described brick body 1 upper surface is provided with small gap 9, grout hole 10 of adjacent small gap 9 one-tenth capable of being combined of adjacent bricks body 1 when paving ground.

The horizontal cross sectional geometry of brick body of the present invention can be designed to other multiple shapes such as square, equilateral triangle, regular hexagon.The sidewall of brick body of the present invention also can be the tenon latch mechanism or the common plane formula structure of other type.

The present invention is not limited to the concrete structure of the foregoing description, and the equivalence exchange of other homogeneous structure all falls within protection scope of the present invention.

Claims
