Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The invention provides a kind of step building block of Collection utilization rainwater, as shown in FIG. 1 to 3, illustrated therein is a kind of preferred embodiment of the present invention.The step building block of Collection utilization rainwater of the present invention comprises the permeable surface layer 1, articulamentum 2, first purifying layer 3, water holding layer 4, second purifying layer 5, the storage cavity 6 that set gradually from top to bottom, the inlet channel 7 be communicated with described storage cavity 6 is provided with bottom described water holding layer 4, the bottom of described storage cavity 6 is provided with outlet conduit 12, and in the building block of upper level step, outlet conduit 12 is connected with inlet channel 7 in the building block of next stage step.
The void content of permeable surface layer 1 of the present invention is 10% ~ 25%, and thickness is 2 ~ 4cm.Described permeable surface layer 1 is formed by one or more layings in pervious asphalt, pervious concrete, water-permeable brick, permeable gravel, be preferably pervious asphalt, pervious concrete, water-permeable brick, permeable gravel are no less than the combination of 2 kinds, and the described permeable surface layer 1 width wide 1 ~ 3cm of each layer comparatively below.The Main Function of described permeable surface layer 1 is by the rainwater rapid osmotic on road surface to underground, and completes the primary filter to rainwater, avoids some bulky grain things to enter underground;
Preferably, described articulamentum 2 is that the aggregate of 0.1 ~ 0.3cm and cementing agent mix by particle diameter, and described aggregate is coarse sand and/or slag, and described cementing agent can be inorganic, organic or the two cementing agent mixed mutually.And the thickness of described articulamentum 2 is 0.8 ~ 1.2cm, and permeability rate is more than or equal to 2.0 × 10
-2cm/s.The Main Function of described articulamentum 2 is for connecting permeable surface layer 1 and the first purifying layer 3.
The thickness of described first purifying layer 3 is 2 ~ 4cm, is made up of resin, haydite, aerobic microbiological, and wherein resin is the full porous resin of aperture at 100 ~ 1000nm, and haydite is the porous ceramic grain of particle diameter at 2 ~ 2.5cm.Its Main Function is: described first purifying layer 3 is better apart from the nearlyer gas permeability in ground, when rain penetration is got off, microorganism can amount reproduction, and on the resin being attached to porous and haydite, utilize microorganism to the removal effect of rain water pollutant as COD, TN, TP and ammonia nitrogen, the catharsis that can carry out rapidly and efficiently to rainwater
As shown in Figure 1, described first purifying layer 3 have water holding layer 4, described water holding layer 4 by particle diameter 1 ~ 2cm graded broken stone lay form, thickness is 2 ~ 4cm, and porosity is 15% ~ 25%.By arranging water holding layer 4, utilize its material void surface can adhere to and keep portion of water, after becoming a fine day, slow evaporation can be raised along with temperature, the other loose structure of reduction surface temperature can adsorb the TP in rainwater, make it form the compound precipitations such as insoluble calcium, iron to get off, play purification and the double action of evaporating.
Preferably, described water holding layer 4 have the second purifying layer 5, the thickness of described second purifying layer 5 is 2 ~ 3cm, be made up of resin, haydite, aerobic microbiological and anaerobe, wherein resin is the full porous resin of aperture at 100 ~ 1000nm, and haydite is the porous ceramic grain of particle diameter at 2 ~ 2.5cm.The action principle of described second purifying layer 5 is roughly the same with the first purifying layer 3, but because the second purifying layer 5 is far away apart from ground, form certain anaerobic environment, the pollutant in the rainwater oozed is slowly purified in water holding layer further by anaerobe, TN mainly in rainwater, strengthens clean-up effect.
Connecting pipe in the present invention is made up of inlet channel 7 and outlet conduit 12.Described inlet channel 7 is positioned at bottom water holding layer 4, and inner-walls of duct diameter is 0.8 ~ 1cm, makes it be receive the water of overflow in the building block of upper level step and enter in the storage cavity 6 of next stage step building block.Outlet conduit 12 is positioned at the bottom of storage cavity 6, inner diameter is 0.6 ~ 0.8cm, slightly be narrower than inlet channel 7, make it to be nested in the inlet channel 7 in the building block of next stage step, water unnecessary in storage cavity 6 can be entered in the building block of next stage step.
As shown in Figure 2, the second cement water-stop sheet 10 that described storage cavity 6 comprises outer wall 8, is horizontally installed on the first cement water-stop sheet 9 in described storage cavity 6 and is longitudinally arranged in described storage cavity 6, the top of described first cement water-stop sheet 9 is provided with guiding gutter 11.In the present invention, " transverse direction " refers to the direction be orthogonal to along step, and " longitudinal direction " refers to the direction along step.Preferably, preferably, the cavity in the building block of upper level step between the first cement water-stop sheet 9 and outer wall 8 is connected with inlet channel 7 in the building block of next stage step by outlet conduit 12.And the height of described storage cavity 6 is 6 ~ 10cm; The groove depth of described guiding gutter 11 is 1 ~ 2cm, and groove width is 3 ~ 5cm.
The rainwater that upper strata has purified can store by described storage cavity 6 of the present invention, after the rainwater height stored exceedes the lower edge of described guiding gutter 11, to fall into next stage step due to gravitational difference, until the step of bottommost, its water (flow) direction A as shown in Figure 3.First cement water-stop sheet 9 and the second cement water-stop sheet 10 can ensure all to store a part of rainwater in every grade of step.When running into dry weather, the water in storage cavity 6 can upwards evaporate, and improves region microclimate, alleviating urban heat island effect.And unnecessary rainwater is downward step by step, until all described storage cavity 6 have filled up rainwater all, ensure the effect of this step collection and purification storm-water system, unnecessary rainwater can connect greening pipe network carries out greenery patches pouring as greening water, saving water resource.Store rainwater in storage cavity 6 in addition, runoff amount of rainfall can also be reduced, reduce outside region and arrange rainwater.
It is should be also step basis of formation that place arranges step building block, can adopt usual manner and carry out Material selec-tion and laying according to actual conditions.Step building block of the present invention can be constructed with reference to following steps:
A. preparation of construction: prune job place, does good material, instrument prepares;
B. according to designing requirement unwrapping wire;
C. step base layer construction, ensures step base fixed;
D. step building block is mated formation, guarantee the nested against one another of the inlet channel of step building block and outlet conduit and the superior and the subordinate's step building block;
E. site clearing, maintenance coming into operation.。
Step building block tool of the present invention has the following advantages:
(1) collect step self and collect the rainwater come, reaching the effect of rainwater-collecting;
(2) multiple purifying structure, the rainwater of collection can purify rear use, saving water resource;
(3) overall structure water conservation, can reduce surface temperature by slow evaporation;
