Abstract
The utility model discloses a unidirectional water permeable sidewalk base course which comprises a unidirectional water permeable sidewalk base course board. Unidirectional water permeable holes (7) running through the unidirectional water permeable sidewalk base course are uniformly distributed on the unidirectional water permeable sidewalk base course board. In the utility model, the capillary ascent phenomenon of water is eliminated by utilizing the water permeability of the unidirectional water permeable holes of the base course to the underground and the compactness of a base course material (such as a cement stabilizing material, an industrial solid waste stabilizing material and a lime stabilizing material), so that water can only enter without going out. As time passes, the underground water level of a corresponding area in which a sidewalk is constructed rises year by year, so that the unidirectional water permeable sidewalk base course is beneficial for locally regulating microclimate and greening cities and towns, improving the human settlement environment and bringing benefits to descendants. The base course does not have water storage effect, so that the integral anti-freeze capacity of the sidewalk is improved. Under the condition of the same bearing capacity with that of the existing water permeable sidewalk, the thickness and the base course and other layers are reduced. Moreover, the base courses are arranged in blocks, so that the unidirectional water permeable sidewalk base course is convenient for maintenance and modification of the town construction, and the maintenance engineering quantity and the engineering cost of the sidewalk can be reduced.
Description
Technical field
The utility model belongs to urban road People's Bank of China, pavement base layer structure technical field, and what relate generally to is a kind of unidirectional permeable sidewalk basic unit.Adaptable across the sidewalk, cities and towns, the construction of road such as pedestrian street, modern country road, factory road, square, open car park, residential community road, park, nonmotorized vehicle lane.
Background technology
At present; In the town road construction; The basic structure of permeable sidewalk, pavement is surface layer, leveling layer, basic unit, bed course, soil matrix from top to bottom, or surface layer, leveling layer, basic unit, soil matrix, or surface layer, leveling layer, basic unit, subbase, bed course, soil matrix.Surface material is permeable brick or permeable cement concrete; The leveling layer material is medium sand or dry cement mortar; Base material is permeable cement concrete or permeable cement stabilization gravel or permeable graded broken stone, and major function is bearing load, permeable, water storage; Subbase course material is permeable graded broken stone; Course is natural gravel; Soil matrix is the suitable various soil of building permeable sidewalk.Existing full impregnated water structure of sidewalk all is to design with the requirement of satisfying permeable and water storage; Its water storage function can cause the general frost resistance in sidewalk poor; Compressive strength, non-deformability are poor, and coming into operation promptly occurs surface layer brick gross distortion, sinking, cracked soon, influences the city appearance of the city; Increase maintenance cost, influence people's go off daily; Pervious function be through the effective drainage porosity that increases structure and select for use as far as possible water permeability preferably road materials realize increasing coefficient of permeability, underground water constantly evaporates in atmosphere because of capillarity rises, and makes loss of underground water serious.What basic unit adopted is materials such as permeable cement concrete or permeable cement stabilization gravel, and thickness is corresponding bigger, and As time goes on, its active porosity can reduce very soon, reduces basic unit's permeability rate greatly, and the capillary climbing of its moisture content does not reduce.
Because the particularity of existing full impregnated water structure of sidewalk effective drainage porosity, during practice of construction, unit in charge of construction is difficult for accurately getting hold of the construction quality that permeable sidewalk reaches effective drainage porosity, and whether difficult check reaches desired effective drainage porosity.
The utility model content
The purpose of the utility model produces thus, proposes a kind of unidirectional permeable sidewalk basic unit, when strengthening the sidewalk working strength; Can effectively strengthen the sidewalk water permeable ability; Avoid underground water to evaporate in a large number, reduce difficulty of construction and construction cost, practice thrift sidewalk, cities and towns maintenance cost in a large number.
For reaching the foregoing invention purpose; The utility model adopts following technical scheme: a kind of unidirectional permeable sidewalk basic unit; Comprise unidirectional permeable sidewalk basal plate, on the basal plate of unidirectional permeable sidewalk, be uniformly distributed with and be provided with the unidirectional permeable hole that runs through unidirectional permeable sidewalk basic unit.
Above-mentioned basic unit is combined by the polylith basal plate, stays 2～10 millimeters shrinkage joint between every.
The reinforcing bar stratum reticulare is set in above-mentioned basic unit, or in base material, mixes steel fibre or synthetic fibers.
Above-mentioned base material is stable type of cement stabilized type, industrial residue, lime stabilization class material.
Steel mesh reinforcement employing bar diameter is 4～12 millimeters in the above-mentioned basic unit, 100～400 millimeters of size of mesh opening.
The above-mentioned content that in base material, mixes steel fibre or synthetic fibers is 1～5% of mixture quality.
The unidirectional permeable hole that is provided with in the above-mentioned basic unit is rectangular opening or circular port; The circular port diameter is 3～12 centimetres; The aperture, top of permeable hole equates with the aperture, bottom or the aperture, top is slightly larger than the aperture, bottom; Pitch of holes is 15～40 centimetres, and the horizontal gross area of permeable hole is 2～10% of the horizontal gross area of basic unit.
Above-mentioned basic unit is rectangle, triangle, arc, polygon, 60～300 millimeters of thickness.
The utility model utilizes the unidirectional permeable hole of basic unit to eliminate the capillary rising phenomenon of water to underground water-permeable, base material (cement stabilized type, stable type of industrial residue, lime stabilization class material) tight ness rating; Thereby moisture content can only be advanced can not be gone out; If things go on like this, the groundwater table of building the corresponding area on sidewalk rises year by year, is beneficial to local microclimate and regulates and urban greening; Improve the human settlement, the offspring benefits future generations.Because basic unit is as the water storage effect, thereby improved the integral anti-freezing ability on sidewalk.With reduced basic unit and other layer thickness under the condition of the equal supporting capacity in existing permeable sidewalk, basic unit's piecemeal is arranged in addition, has made things convenient for the maintenance of city-building from now on, transformation, can reduce sidewalk maintenance works amount and engineering cost.Standardized designs and standardized construction be can realize, design efficiency and efficiency of construction improved.
