The technical solution used in the present invention is:
Strengthen a method for gentle slope, city porous pavement permeability performance, comprise the following steps:
(1) before porous pavement is laid in region, gentle slope, city, carry out mima type microrelief arrangement, form the intercepting drain of horizontal direction;
(2) punch in intercepting drain;
(3) add in the hole accomplished fluently hard, porous granular material and light pressure is guaranteed firm;
(4) carry out conventional porous pavement and lay operation.
The gentle slope porous pavement mentioned in step (1) comprises concrete structure road surface and/or permeable brick structure road surface.
Further, region, indication gentle slope is the gradient in the region of 5 °-30 °.
Further, described intercepting drain is shallow die bed, and the degree of depth is 2-10cm, and bottom width is 2-10cm.Preferably, the degree of depth is 5cm, and bottom width is 5cm.
Further, the spacing on gently sloping surface between intercepting drain is every 1-10m mono-.Preferably, ditch spacing is 5m.
In step (2) intercepting drain, punching construction is after paved road mima type microrelief arranges, before the operations such as paving sand, compacting, tile work;
Further, in intercepting drain, punching spacing is 0.5-1.5m, is preferably spacing 1m.
Further, the diameter of described hole is 2-5cm, is preferably diameter 5cm;
Further, the degree of depth of described hole is 0.5-1.5m, is preferably degree of depth 1m.
Further, the granular material of step (3) hard used, porous is used for being formed with the Vertical Infiltration pore channel of support, is preferably charcoal granular material.
Further, described charcoal granular material is the cracking under anoxic, 300-600 DEG C condition of hard agriculture and forestry organic waste material, and is crushed to diameter <1cm, obtained.This material has the features such as stability is high, degree of porosity is large, density is little.
Further, described hard agriculture and forestry organic waste material comprise in branch, corn ear one or both.
The conventional porous pavement that step (4) is carried out is laid operation and is comprised: paving sand, compacting, tile work etc.
Principle of the present invention is: carry out mima type microrelief arrangement before adopting region, gentle slope, city permeable and retain Soil Slope top layer runoff, simultaneously by soil punching in intercepting drain and packing material forms the method for vertical macrovoid passage, build artificial macrovoid preferential flow system, formation top layer porous pavement is permeable, lower floor's level ditch of runoff harvesting classification retains, the gently sloping surface Infiltration system of vertical soil hole water guide, strengthen the precipitation infiltration performance of gentle slope porous pavement entirety, effectively reduce flow path surface.
Effective effect of the present invention comprises:
The invention provides a kind of method strengthening gentle slope, city porous pavement permeability performance, there are market prospects widely: can be widely used in the hard surface construction of city, as: city square greenery patches, greenbelt in little residential region, Road Green Space, forest park etc.
(1) under the present invention effectively can improve gentle slope, city porous pavement, infiltration divides the infiltration capacity in lower soil body, while retaining domatic pathway, more precipitation is quickly transferred in deep soil, effectively reduces Soil Reservoir under flow path surface, charging point.
(2) aperture of punching in the present invention is less, and hard is filled in employing, porous material is supported, and can not destroy the structural stability of gentle slope, city porous pavement.
(3) the preferred charcoal of holes filling material of the present invention, this material has drawn from agriculture and forestry organic waste material, contributes to the recycling of agriculture and forestry organic waste material, simultaneously as a kind of high stability material, can play long-term support, maintain effect pore space structure.
(4) the present invention has simple, convenient, the advantages such as engineering quantity is little.
