Abstract

The invention provides a green fire passage, which includes a packed soil layer and a rammed 37 lime-earth layer and is characterized in that a sand cushion layer that is favorable for the water penetration and soil conservation is laid on the basis of the rammed 37 lime-earth layer; grass-planting grids are laid on the basis of the sand cushion layer and planting soil is filled in the grass grids; and grass seeds are planted in the planting soil which is laid on the basis of the grass grids to form a vegetation or green sod is laid on the basis of the plant soil after the planting soil is laid. The invention plants lawn or lays green sod on the surface of the fire passage under the precondition of meeting the fire-control design specification and emergent fire-control traffic; simultaneously, the invention can disperse the vehicle and pedestrian, improve the greening rate, absorb rainwater, regulate the temperature and humidity, decrease the heat island effect and improve the living environment, and has bright prospect for generalization in the northwestern arid area where the rainfall is low and the evaporative capacity is high.

Description

Green fire-fighting passage

Technical field the invention belongs to the road construction technical field, is specifically related to a kind of sub-district green fire-fighting passage.

Background technology is present, and common passageway for fire apparatus great majority are laid by hard materials such as concrete, pitch, stone materials, only brings into play fire-fighting, emergent and current function.Because China's " Code for fire protection design of high rise buildings " GB 50045-95 4.3.4 bar is clearly stipulated: the width in fire-fighting track should be less than 4.0m.For satisfying the width requirement of passageway for fire apparatus, tend to take the more area in residential quarter, both caused the mixed row of people from residential quarter car, weakened again the greening of living environment, obstruction soil drinks up the rain, and with significantly " heat island " effect generation, is unfavorable for the construction of health, ecology and green residential quarter.

Summary of the invention the object of the present invention is to provide a kind of fire-fighting emergent needs that can satisfy in emergency circumstances, can improve community's green percentage again, improves the green fire-fighting passage of community's ecological environment.

For achieving the above object, the technical scheme taked of the present invention is:

A kind of green fire-fighting passage comprises rammed earth layer and 37 lime earth rammed layer, it is characterized in that: the sand cushion that is beneficial to permeable and soil conservation is laid on the basis at described 37 lime earth rammed layer; Grass-planting grid is laid on basis at sand cushion, interior filling planting soil between the grass planting checkerwork cell; Lay planting soil layer sowing grass-seed on the basis of grass-planting grid and form vegetation, or after the planting soil layer is laid on the basis of grass-planting grid, lay turf.

The thickness of described 37 lime earth rammed layer is 200～500mm; Sand bedding course thickness is 30～100mm; Being used to sow the planting soil layer thickness that grass-seed lays is 40～100mm, and the planting soil layer thickness that is used to lay turf is 0～50mm.

For further being beneficial to the absorption of rainwater, also be provided with sand pebble layer between described 37 lime earth rammed layer and the sand cushion.

The thickness of described sand pebble layer is 80～150mm.

Above-mentioned green fire-fighting passage provided by the invention, under the prerequisite of guaranteeing the current function of design for fire protection code requirement and fire-fighting emergent, surperficial turf plant or laying turf in the passageway for fire apparatus, can guarantee fire-fighting emergent needs in emergency circumstances, also play the sub-district human and vehicle shunting simultaneously, improve green percentage, receive rainwater, regulate humiture, reduce heat island effect, improve the function of dwelling environment, the northwest arid area little at amount of precipitation, that evaporation capacity is big has promotion prospect widely.

Description of drawings Fig. 1 is the cross-sectional view of green fire-fighting passage basis embodiment

Fig. 2 optimizes the cross-sectional view of embodiment for green fire-fighting passage

The specific embodiment for technological means, character of innovation that the present invention is realized, achieve the goal and effect is easy to understand, further set forth the present invention below in conjunction with accompanying drawing.

As shown in Figure 1, with original rammed earth, guarantee compacting factor 〉=0.93, form the rammed earth layer 1 that reaches the regulation packing, lay 37 lime earth and compacting on the basis of rammed earth layer 1, form the thick 37 lime earth rammed layer 2 of 300mm; Lay sand (husky in preferably adopting) and compacting on the basis of 37 lime earth rammed layer 2, form the thick sand cushion of 100mm, be beneficial to permeable and soil conservation; Grass-planting grid 4 is laid on basis at sand cushion 3, filling planting soil between the hole of grass-planting grid 4 is (according to the plantation soil property, preferably mix at least 30% peat), the grass-planting grid 4 of laying is made by 100% high density polyethylene (HDPE) regenerated plastics, and is extremely light, be easy to transportation, simple installation, quick has excellent permeability, can prevent that the lawn is because of tire extruding depressed deformation, and reusable edible, the weight that its surface can be carried can reach 200 tons/meter ²Lay the plantation soil layer 5 (according to the plantation soil property, preferably mixing at least 30% peat) of 50mm on the basis of grass-planting grid 4, sow grass-seed in the plantation soil layer 5, grass-seed grows into vegetation.

In order more to help the growth of plants on surface, can scheme shown in Figure 1 basic enterprising one-step optimization, as shown shown in 2:

For further being beneficial to the absorption of rainwater, lay sandy gravel and compacting on the described 37 lime earth rammed layer 2, form the good sand pebble layer 6 of water permeability, the thickness of sand pebble layer 6 is 100mm; Re-lay sand (husky in preferably adopting) and compacting on the basis of sand pebble layer 6, form the thick sand cushion 3 of 30mm; Grass-planting grid 4 is laid on basis at sand cushion 3, lays the thick planting soil of 50mm on the grass-planting grid 4, directly lays turf 7 on the planting soil.

For those skilled in the art, on the basis of above-described embodiment, can suitably adjust each layer thickness according to the soil property situation, can realize purpose of the present invention equally, still, above-mentioned various variations obviously should be in the protection domain of claims of the present invention.
