Description

A kind of fast row stores filter formula road surface

Technical field

The utility model belongs to brick or concrete duct field, relates to a kind of fast row and stores filter formula road surface.

Background technology

At present, urban road, square, commercial street, pavement, parking lot, community and parkway extensively make With dense bitumen compound, cement concrete and the material such as granite, marble, urban surface is not gradually by Permeable surface layer covers.But this pavement structure exists some problems, as urban groundwater can not get supplementing, ground Table water cannot ooze by under pavement structure, compromises the water balance in city, have impact on the growth of urban surface plant, Destroy the ecological balance of urban surface simultaneously.In big city, level of ground water loses in downward trend year by year, the soil body , easily there is fault sag in the ability of balance in situ；Increase the weight of urban waterlogging disaster, due to the road surface of surface compact Structure the rainy day can not draining in time, inside pavement structure, lack water storage design simultaneously, moisture penetration can be caused To subgrade soils, form destabilization of roadbed；Current collection device, somewhat expensive and engineering need to be set up in road both sides Measure huge；Water body one-way flow, pavement structure does not possess long-time retaining storage capacity, and water body flow direction is One-way flow.

Utility model content

The purpose of this utility model is to provide a kind of fast row to store filter formula road surface, solves current pavement structure and makes city City's underground water can not get supplementing, and surface water cannot ooze by under pavement structure, causes roadbed to damage, pavement structure Not possessing long-time retaining storage capacity, pavement temperature is high, compromises the isorrheic problem in city.

The utility model be employed technical scheme comprise that and knitted by asphalt concrete layer, the first geotechnique the most successively Nitride layer, sub-surface and the second geotextile layer composition, wherein sub-surface uses super absorbent resin layer, storage Water crushed rock base course, biozeolite layer superposition from top to bottom composition, described bituminous concrete layer porosity is not less than 22%.

Further, described asphalt concrete layer is open-shelf range OGFC asphalt concrete material.

Further, described concrete layer thickness be 5-10cm, super absorbent resin layer thickness be 3-5cm, water storage Crushed rock base course thickness is 50-70cm, biozeolite layer thickness is 5-10cm.

The beneficial effects of the utility model are that surface water can ooze by under pavement structure, and when road surface possesses long Between retaining storage capacity, can slowly discharge moisture for a long time, the water discharged both can permeate downwards supplementary Underground water source, upwards can evaporate at high temperature season again, reduces road table temperature, reduces urban heat land effect.

Accompanying drawing explanation

Fig. 1 is that the utility model arranges storage filter formula pavement structure schematic diagram soon.

In figure, 1. asphalt concrete layer, 2. the first geotextile layer, 3. sub-surface, 4. the second geotextile layer, 301. super absorbent resin layers, 302. water storage crushed rock base courses, 303. biozeolite layers.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is described in detail.

The utility model asphalt concrete layer 1 as shown in Figure 1 preferably employs open-shelf range OGFC (Open Graded Friction Course) asphalt concrete material, its design porosity ensures not less than 22%. Under asphalt concrete layer 1 one layer is first geotextile layer, the i.e. first geotextile layer 2, the first soil Being sub-surface 3 below work tissue layer 2, sub-surface 3 uses super absorbent resin layer 301, water storage rubble Basic unit 302 (water-loss reducer), biozeolite layer 303 (drainage agent) superposition composition.Bottom one layer is second Geotextile layer that is second geotextile layer 4.The utility model pavement structure asphalt concrete layer 1 thickness is 5-10cm, super absorbent resin layer 301 thickness is 3-5cm, water storage crushed rock base course 302 thickness is 50-70cm, Biozeolite layer 303 thickness is 5-10cm.

The feature that fast row of the present utility model stores filter formula pavement structure is as follows:

(1) possesses the performance on conventional drainage road surface

Use macrovoid (voidage is not less than 22%) OGFC bituminous concrete surfacing as road surface Layer, can make rainwater enter inside pavement structure quickly through road surface, meet the requirement of general drainage pavement, with Time top layer, macroporous road traffic noise is also had obvious sound deadening.

(2) storage filter formula sub-surface design is used

Eliminate the full impregnated water tube hose in conventional discharge pavement structure, use the additional water-loss reducer of rubble water storage basic unit Layer, the design of drainage oxidant layer.Water-loss reducer uses super absorbent resin, and it is that a kind of water absorbing capacity is the strongest Functional high molecule material.Nontoxic, repeatedly release water, water suction, be mainly used in arid area crop growth, By its mixing in road gallet water storage basic unit, once rainfall, can quickly absorb and exceed own vol 200 Water body again, prevents precipitation leakage excessive, damages roadbed.Water-loss reducer has water conservation concurrently simultaneously, the function of retaining can Slowly to discharge moisture for a long time, the water discharged both can permeate downwards recharge of groundwater source, again can be High temperature season upwards evaporates, and reduces road table temperature, reduces urban heat land effect.Drainage agent uses biological boiling Stone, biozeolite is the sedimentary rock sprayed through volcano, possess the adsorptivity to organic one's share of expenses for a joint undertaking, have filter, The effects such as natural decoloring agent and removal poisonous and harmful substance, use biozeolite can permeate pathway table Water body carries out purification filtering effect, it is ensured that the safety of underground water source.

(3) twice Geotextiles Design, it is ensured that the monolithic stability of pavement structure

Novel fast row stores filter formula Pavement Structure Design and uses twice geotextile layer, and first geotextile layer is arranged Below top layer, road, it is therefore an objective to reinforced surface layer further, improve bearing capacity and the surface layer rutting resistance on road surface. Second geotextile layer is arranged between drainage basic unit and roadbed, prevents soil particle from entering base by pump-absorb action Layer.

Pavement structure of the present utility model is also advantageous in that: construction is simple, and cost performance is high, and novel fast row stores filter formula Pavement structure and the construction technology on plain asphalt road surface, construction equipment are essentially identical.With other Quick drainage road surfaces Comparing, decrease the rainwater-collecting processing equipment of road both sides, its cost performance is higher.Use water-loss reducer and drainage The design of agent makes moisture the most slowly to discharge, two-way penetration, has higher social benefit and environmental protection effect Benefit.

The utility model pavement structure breaks through conventional road Pavement Structure Design theory, and porous pavement can be straight by rainwater Connect and permeate the ground rather than enter river, lake through special current collection processing system implementing.Rainwater is by pavement structure Being filtrated to get purification, maintain the steady of earth's surface hydraulic pressure, supplement groundwater resources, water body can be on road simultaneously Face structure can slowly discharge with long-time storage, both can complete the discharge under current direction the short time and collect, Slowly can upwards discharge for a long time again, reduce road table temperature, become " the meeting with good ecological environment benefit Breathe " pavement structure.

The above is only to better embodiment of the present utility model, not makees the utility model any Pro forma restriction, every any simply repaiies made for any of the above embodiments according to technical spirit of the present utility model Change, equivalent variations and modification, belong in the range of technical solutions of the utility model.
