Description

For the water permeable device in sponge urban ecology ground system

Technical field

The utility model is related to drainage system field, more particularly to for the permeable dress in sponge urban ecology ground system Put.

Background technology

Sponge city, is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band The aspects such as the natural calamity come have good " elasticity ", also referred to as " water elasticity city ", and in sponge city the most It is important that being arranged on the permeable system on surface, most commonly seen permeable system often adopts laying water-permeable brick permeable to reach Effect.

Simple permeable system can not meet the requirement of people, such as in Publication No. " CN201520735337 .7 " State's patent is disclosed and a kind of increases being applied in sponge urban ecology ground system of tubaeform water-permeable pipe in water permeable device Water permeable device, but such structure and it is not sufficiently stable, cause road surface bearing capacity not enough, sponge city is difficult to popularize in an all-round way.

Utility model content

The purpose of this utility model be to provide a kind of bearing capacity it is higher in sponge urban ecology ground system Water permeable device.

Above-mentioned technical purpose of the present utility model technical scheme is that, one kind be used for sponge city Water permeable device in ecological ground system, including pervious bed, also including the water guide layer being arranged on soil horizon, are placed on water guide layer On firm layer, firm layer includes being mutually connected vertically and fissure of displacement overlap joint polylith reinforcing plate in the same plane, adjacent reinforcement Cavity is surrounded between plate, pervious bed is filled in cavity.

By adopting above-mentioned technical proposal, one layer of firm layer is first laid, then pervious bed is filled in firm layer, it is such Setting does not only affect the original water permeability of pervious bed, and the setting of firm layer can also reinforce pervious bed, make original holding The little pervious bed of weight can bear more weight, and if the setting of reinforcing plate the pervious bed of an originally monoblock is divided into Dry fraction, because shape is less the deformation quantity that can occur when expanding with heat and contract with cold is also smaller, such setting can be with Help pervious bed form when expanding with heat and contract with cold that too big change will not occur.

Preferably, firm layer staggers in the height direction between the reinforcing plate of multiple-level stack and adjacent firm layer.

By adopting above-mentioned technical proposal, more than one layer of firm layer is laid in water permeable device, but multilayer consolidates layer, Multiple firm layers are crisscross arranged, and such setting makes permeable Rotating fields more consolidate.

Preferably, the T-shaped sliding groove that T-shaped projection is engaged with T-shaped projection is provided between adjacent reinforcing plate, phase Coordinated by T-shaped projection and T-shaped sliding groove sliding between adjacent reinforcing plate.

Difficulty of construction can be reduced by adopting above-mentioned technical proposal, such setting, because two pieces of reinforcing plates are in construction During often using welding, but find welding position accurately in welding process compared with the consuming time, and pass through T-shaped sliding groove and T The setting of type projection carries out pre-determined bit to two pieces of reinforcing plates being connected with each other, and such being arranged on can quickly by two pieces in construction The reinforcing plate that needs are connected with each other will again be welded according to the track of sliding groove after reinforcing plate correspondence inlay card, be substantially increased Operating efficiency.

Preferably, the pervious bed includes successively main pervious bed, cushion.

By adopting above-mentioned technical proposal, when only arranging single pervious bed, moisture directly permeates downwards from water guide layer, this Although the setting of sample can quickly arrange light ponding, moisture is not but made full use of, and the cushion for arranging more, can one Determine buffering moisture in degree to permeate downwards and store portion of water in road surface, protection road surface will not be sent out in solar exposure Scald or even damaged.

Preferably, longitudinally offering multiple water storage grooves on the cushion, water storage groove inner surface is coated by waterproof Material.

By adopting above-mentioned technical proposal, water storage groove is longitudinally provided with cushion, moisture is permeated downwards by permeable formation When, have moist part of the part deposit of moisture in water storage groove, instantly when GLITTERING DROPS direct projection ground, in water storage groove Evaporate upwards, it is ensured that the moisture in pervious bed, will not ftracture because of being exposed to the sun all.

Preferably, also laterally offering multiple guiding gutters on the cushion.

By adopting above-mentioned technical proposal, guiding gutter is laterally additionally provided with cushion, when moisture permeates downwards, wherein one Part is flowed away by guiding gutter, can slow down osmotic pressure herein, secondly, if the other end of guiding gutter leads to Soil Surrounding, this Part can be fed in soil by the water of guiding gutter.

Preferably, guiding gutter is connected with water storage groove.

By adopting above-mentioned technical proposal, guiding gutter is connected with water storage groove, moisture will not directly pass through guiding gutter stream Lose, but first save bit by bit in water storage groove, the part overflowed is flowed away by guiding gutter after water product is full in water storage groove, so Setting can slow down discharge and flow rate in guiding gutter, periphery sewer pressure mistake will not be caused because flowing is too fast Greatly.

Preferably, the water guide layer center is recessed downwards forms cistern.

By adopting above-mentioned technical proposal, water guide layer middle body forms a small-sized cistern, stronger in illumination Area, due to road surface specific heat capacity it is less, so can because sunlight irradiation cause road surface hot or even pavement cracking, but by sunlight Acting of the heat that direct projection is produced to moisture in cistern, by water transpiration, retarding heat, so as to reduce pavement temperature.

Preferably, being provided with multiple through holes through whole water guide layer on water guide layer.

By adopting above-mentioned technical proposal, avoid arranging through hole on the position of cistern in water guide layer, moisture is from pervious bed Middle to permeate, a portion is stored in cistern, and another part can enter buried channel by through hole.

Preferably, water guide layer is formed by waterproof material coating, pervious bed is formed by seepy material coating.

By adopting above-mentioned technical proposal, one layer of waterproof material of coating can be effectively prevented moisture and ooze on water guide layer Thoroughly, effectively moisture is blocked in into this layer, prevents from being oozed under continuing；It is this and the material that pervious bed is used is seepy material Setting can to the full extent help the enforcement of this scheme.

In sum, the utility model has the advantages that：One layer of firm layer is inserted into original pervious bed, Reinforcing plate is orthogonal and the fissure of displacement is overlapped in firm layer, such to arrange the bearing capacity that not only improve original pervious bed, And such setting, pervious bed is filled in firm layer and quite pervious bed is separated into each small area grid, can keep away Exempt from road surface to expand with heat and contract with cold cracking.
