Abstract

A method for laying the bricks of water-permeable pedestrian include such steps as tamping the bed of pedestrian, spreading broken stone layer, spreading the mixture of ballast and stone powder, levelling, spraying water, compacting, spreading liner layer of broken stone and fine sand, spraying water and laying bricks. Its advantages are high air and water permeability, smooth pavement, high load-bearing power, and low cost.

Description

Porous brickwalk laying method

Technical field:

The present invention relates to municipal and environment-friendly engineering field, be specifically related to a kind of paving method of pavement brick.

Background technology:

The paving method of existing pavement brick, generally be to adopt following dual mode after the tabia spreading: a kind of is full sand cushion, lays the pavement brick above the sand, though full sand cushion good water permeability, shortcoming is not durable, not load-bearing.When raining suddenly, the sand bed of pavement brick bottom is run off by rain drop erosion, causes the paving out-of-flatness of pavement brick, and the pavement brick of this full sand place mat is subdued easy sinking when motor vehicle, makes the road surface become uneven.Another kind is a concrete cushion, though this bed course resistant to pressure, steadiness are good, shortcoming is airtight, waterproof, and the brick face fades comparatively fast.This methods engineering cost height, the engineering time is long, and is unfavorable for the city water conservation.It is reported that the groundwater table in many cities is all ceaselessly descending, and the recovery of urban groundwater position is mainly by precipitation, but lay the pavement brick owing to do bed course with concrete, cause the water permeability forfeiture, make a large amount of rainwater flow into sewer in vain, underground water can not get replenishing.

Summary of the invention:

The purpose of this invention is to provide a kind of porous brickwalk laying method, this method has that speed of application is fast, construction costs is low, road surface weight capacity height, the characteristics that the water-permeable and air permeable performance is good.The present invention realizes by following steps: one, with rammer machine or road roller the former soil layer of roadbed is tamped or compacting; Two, lay macadam: rubble is layered on above the former soil layer of compacting or compacting, the laying depth of its rubble is 30-200mm; Three, lay the grating layer: rock ballast and stone flour are layered on above the macadam, push away the water spray compacting of flat back, the laying depth of its grating layer is 10-100mm; Four, lay laying: behind rubble and fine sand mixing, be layered on above the grating layer, real with depositing in water, the laying depth of its laying is 10-50mm; Five, lay the pavement brick: with the rammer machine laying is rammed and put down, lay the pavement brick then, the thickness of pavement brick is 50-80mm.The average diameter of the used rubble of described macadam is 1-3cm or 2-4cm; The average diameter of described grating layer rock ballast is 0.1-2mm, and the particle diameter of stone flour is 0.01-0.1mm; The volume ratio of rock ballast and stone flour is: 1: 1-2; The rubble of described laying and the volume ratio of fine sand are 1: 1; The diameter of rubble is 0.3-0.5cm, and fine sand is a common building sand.Step 1 usefulness rammer machine of the present invention or road roller are with the original soil rammed of roadbed, to replace the tabia of prior art; The used rubble of each bed course, rock ballast, stone flour are to replace cement or flyash.The present invention is applicable to mating formation of sidewalk, square, parking lot, roadway.The present invention has following seven big advantages: one, the water-permeable and air permeable performance is good: rainwater can in time permeate the ground when raining, help the rise of urban groundwater position, fine, underground aqueous vapor can be distributed in air by the road surface of laying, can regulate the humidity of urban air, help the improvement of ecological environment; Two, pavement brick brick face is smooth, and color is beautiful; Three, the basis firm, can anti-heavy-duty vehicle spreading; Four, severe cold frost heave can not occur winter; Five, exempt to lay underground drain water piping, therefore remove the maintenance of daily drainage from; Six, reduce construction costs more than 25%, seven, improved speed of application.

Description of drawings:

Fig. 1 is the schematic diagram of the present invention macadam, grating layer, laying and the pavement brick laid.

The specific embodiment:

The specific embodiment one: (referring to Fig. 1) present embodiment realizes by following steps: one, with rammer machine or road roller the former soil layer of roadbed is tamped or compacting; Two, lay macadam: rubble is layered on above the former soil layer of compacting or compacting, the laying depth of its rubble is 30-200mm; Three, lay the grating layer: rock ballast and stone flour are layered on above the macadam, push away the water spray compacting of flat back, the laying depth of its grating layer is 10-100mm; Four, lay laying: behind rubble and fine sand mixing, be layered on above the grating layer, real with depositing in water, the laying depth of its laying is 10-50mm; Five, lay the pavement brick: with the rammer machine laying is rammed and put down, lay the pavement brick then, the thickness of pavement brick is 50-80mm.The average diameter of the used rubble of described macadam is 1-3cm or 2-4cm; The average diameter of described grating layer rock ballast is 0.1-2mm, and the particle diameter of stone flour is 0.01-0.1mm; The volume ratio of rock ballast and stone flour is: 1: 1-2; The rubble of described laying and the volume ratio of fine sand are 1: 1; The diameter of rubble is 0.3-0.5cm, and fine sand is a common building sand.

The present invention is used for 12000 meter 2 engineering in a parking lot of certain city square, and not only meet load requirement, and exempt to establish underground drain water piping, parking lot ponding not when raining heavily, water all is penetrated into underground.

Claims

1. porous brickwalk laying method, it is realized by following steps: one, with former soil layer compacting or the compacting with roadbed of rammer machine or road roller; Two, lay macadam: rubble is layered on above the former soil layer of compacting or compacting, the laying depth of its rubble is 30～200mm; Three, lay the grating layer: rock ballast and stone flour are layered on above the macadam, push away the water spray compacting of flat back, the laying depth of its grating layer is 10～100mm; Four, lay laying: behind rubble and fine sand mixing, be layered on above the grating layer, real with depositing in water, the laying depth of its laying is 10～50mm; Five, lay the pavement brick: laying is rammed flat with the rammer machine, lay the pavement brick then, the thickness of pavement brick is 50-80mm, the average diameter of the used rubble of described macadam is 1～3cm or 2～4cm, the average diameter that it is characterized in that described grating layer rock ballast is 0.1～2mm, and the particle diameter of stone flour is 0.01～0.1mm; The volume ratio of rock ballast and stone flour is: 1: (1～2), and the rubble of described laying and the volume ratio of fine sand are 1: 1; The diameter of rubble is 0.3-0.5cm, and fine sand is a common building sand.
