Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is done further in detailThin description.
The step building block that the utility model provides a kind of collection to utilize rainwater, as Fig. 1～Fig. 3Shown in, wherein show a kind of preferred embodiment of the present utility model. Receipts of the present utility modelCollection utilizes the step building block of rainwater to comprise the permeable surface layer 1, the articulamentum that set gradually from top to bottom2, the first purifying layer 3, water holding layer 4, the second purifying layer 5, water storage cavity 6, described water holding layer4 bottoms are provided with the inlet channel 7 being communicated with described water storage cavity 6, the end of described water storage cavity 6Portion is provided with outlet conduit 12, and outlet conduit 12 and next stage platform in the building block of upper level stepIn the building block of rank, inlet channel 7 is connected.
The voidage of permeable surface layer 1 of the present utility model is 10%～25%, and thickness is 2～4cm.Described permeable surface layer 1 is by one in pervious asphalt, pervious concrete, water-permeable brick, permeable gravelKind or multiple laying form, and are preferably pervious asphalt, pervious concrete, water-permeable brick, permeable gravelStone is no less than the combination of 2 kinds, and described permeable surface layer 1 width each layer of wide 1～3cm below.The Main Function of described permeable surface layer 1 is that the rainwater rapid osmotic on road surface is extremely underground, and completesTo the primary filter of rainwater, avoid some bulky grain things to enter underground;
Preferably, described articulamentum 2 is 0.1～0.3cm by particle diameter aggregate and binding agent mixForm, described aggregate is coarse sand and/or slag, described binding agent can be inorganic, organic or the twoThe binding agent mixing mutually. And the thickness of described articulamentum 2 is 0.8～1.2cm, and permeability rate is greater thanOr equal 2.0 × 10-2Cm/s. The Main Function of described articulamentum 2 for connect permeable surface layer 1 withThe first purifying layer 3.
The thickness of described the first purifying layer 3 is 2～4cm, by resin, haydite, aerobic microbiologicalComposition, wherein resin is the full porous resin of aperture at 100～1000nm, haydite is that particle diameter existsThe porous ceramic grain of 2～2.5cm. Its Main Function is: described the first purifying layer 3 apart from groundNearly gas permeability is better, and in the time that rain penetration is got off, microorganism can amount reproduction, and is attached to manyOn the resin and haydite in hole, utilize microorganism to rain water pollutant as COD, TN, TP andThe removal effect of ammonia nitrogen, can carry out catharsis rapidly and efficiently to rainwater
As shown in Figure 1, under described the first purifying layer 3, be provided with water holding layer 4, described water holding layer4 graded broken stones by particle diameter 1～2cm are laid and are formed, and thickness is 2～4cm, and porosity is15%～25%. By water holding layer 4 is set, utilize its material void surface to adhere to and to keepPortion of water, after becoming a fine day, can, along with the temperature slow evaporation that raises, reduce surface temperatureLoose structure can adsorb the TP in rainwater in addition, makes it form the chemical combination such as insoluble calcium, ironThing precipitates, and plays the double action purifying with evaporation.
Preferably, under described water holding layer 4, be provided with the second purifying layer 5, described the second purifying layer5 thickness is 2～3cm, formed by resin, haydite, aerobic microbiological and anaerobe,Wherein resin is the full porous resin of aperture at 100～1000nm, and haydite is that particle diameter is at 2～2.5cmPorous ceramic grain. The action principle of described the second purifying layer 5 and the first purifying layer 3 are roughly the same,But because the second purifying layer 5 is far away apart from ground, form certain anaerobic environment, can pass throughPollutant in the rainwater that anaerobe is oozed under further purifying in water holding layer slowly, is mainlyTN in rainwater, strengthens clean-up effect.
Connecting pipe in the utility model is made up of inlet channel 7 and outlet conduit 12. InstituteState inlet channel 7 and be positioned at water holding layer 4 bottom, inner-walls of duct diameter is 0.8～1cm, makes itFor receiving the water of overflow in the building block of upper level step and entering the water storage cavity of next stage step building blockIn 6. Outlet conduit 12 is positioned at the bottom of water storage cavity 6, and inner diameter is 0.6～0.8cm,Slightly be narrower than inlet channel 7, make it to be nested into the inlet channel 7 in the building block of next stage stepIn, water unnecessary in water storage cavity 6 can be entered in the building block of next stage step.
As shown in Figure 2, described water storage cavity 6 comprises outer wall 8, is horizontally installed on described water storageThe first cement water-stop sheet 9 in cavity 6 and be longitudinally arranged in described water storage cavity 6Two cement water-stop sheets 10, the top of described the first cement water-stop sheet 9 is provided with guiding gutter 11. At thisIn utility model, " laterally " refers to the direction being orthogonal to along step, and " longitudinally " refers to along platformThe direction on rank. Preferably, preferably, the first cement water-stop sheet 9 Hes in the building block of upper level stepCavity between outer wall 8 is by inlet channel 7 in outlet conduit 12 and the building block of next stage stepBe connected. And the height of described water storage cavity 6 is 6～10cm; The groove of described guiding gutter 11Be 1～2cm deeply, groove width is 3～5cm.
The rainwater that described water storage cavity 6 of the present utility model can purify upper strata stores upDeposit, when the rainwater height storing exceedes behind the lower edge of described guiding gutter 11, will fall due to gravitational differenceEnter in next stage step, until the step of bottommost, its water (flow) direction A as shown in Figure 3. TheOne cement water-stop sheet 9 and the second cement water-stop sheet 10 can ensure all to store in every grade of step a part ofRainwater. In the time running into arid weather, the water in water storage cavity 6 can upwards evaporate, upgrading areaTerritory miniclimate, alleviating urban heat island effect. And unnecessary rainwater is downward step by step, until all institutesState water storage cavity 6 and all filled up rainwater, ensure the effect of this step collection and purification storm-water system,Unnecessary rainwater can connect greening pipe network and carry out the pouring in greenery patches as greening water, saves water moneySource. The interior storage rainwater of water storage cavity 6, can also reduce runoff amount of rainfall in addition, reduces regionOuter row's rainwater.
It is should be also step basis of formation that place arranges step building block, can adopt usual manner alsoCarry out material selection and laying according to actual conditions. Step building block of the present utility model can with reference to asLower step is constructed:
A. preparation of construction: prune job place, do good material, instrument preparation;
