Specific embodiment
Below by drawings and examples, technical scheme of the present invention is described in further detail.
The present invention provides a kind of step building blocks of Collection utilization rainwater, as shown in FIG. 1 to 3, this hair are shown
A kind of bright preferred embodiment.The step building block of the Collection utilization rainwater of the present invention includes setting gradually from top to bottom permeable
Face layer 1, articulamentum 2, the first purifying layer 3, water holding layer 4, the second purifying layer 5, storage cavity 6,4 bottom of water holding layer be equipped with
The inlet channel 7 that the storage cavity 6 connects, the bottom of the storage cavity 6 are equipped with outlet conduit 12, and upper level step
Outlet conduit 12 is connected with inlet channel 7 in next stage step building block in building block.
The voidage of the permeable face layer 1 of the present invention is 10%~25%, and thickness is 2~4cm.The permeable face layer 1 is by saturating
One or more in bituminous grout, pervious concrete, water-permeable brick, permeable gravel are laid with, preferably pervious asphalt, permeable mixed
Solidifying soil, water-permeable brick, permeable gravel are no less than 2 kinds of combination, and each 1~3cm of slice width of the permeable face 1 width lower of layer.
The main function of the permeable face layer 1 is by the rainwater rapid osmotic on road surface to underground, and completes the primary filter to rainwater, is kept away
Exempt from some bulky grain objects and enter underground；
Preferably, the articulamentum 2 is mixed by the aggregate and binding agent that grain size is 0.1~0.3cm, and the aggregate is
Coarse sand and/or slag, the binding agent can be the binding agent that inorganic, organic or the two mixes.And the thickness of the articulamentum 2
It spends for 0.8~1.2cm, infiltration coefficient is greater than or equal to 2.0 × 10-2cm/s.The main function of the articulamentum 2 is permeable to connect
Face layer 1 and the first purifying layer 3.
The thickness of first purifying layer 3 is 2~4cm, is made of resin, haydite, aerobic microbiological, and wherein resin is hole
Diameter 100~1000nm full porous resin, haydite for grain size 2~2.5cm porous ceramic grain.Its main function is：It is described
First purifying layer 3 is preferable apart from the nearlyer gas permeability in ground, when rain penetration is got off, microorganism can amount reproduction, and be attached to
On porous resin and haydite, the removal of rain water pollutant such as COD, TN, TP and ammonia nitrogen are acted on using microorganism, it can be to rain
Water carries out catharsis rapidly and efficiently
As shown in Figure 1, first purifying layer 3 has a water holding layer 4, the water holding layer 4 by 1~2cm of grain size grade
It is laid with rubble, thickness is 2~4cm, and porosity is 15%~25%.By setting water holding layer 4, its material void is utilized
Surface can be adhered to and keep portion of water, after becoming a fine day, can increase slow evaporation with temperature, it is another to reduce surface temperature
Outer porous structure can adsorb the TP in rainwater, form it into the compound precipitations such as insoluble calcium, iron and get off, play purification with
The double action of evaporation.
Preferably, the water holding layer 4 has the second purifying layer 5, and the thickness of second purifying layer 5 is 2~3cm,
It is made of resin, haydite, aerobic microbiological and anaerobe, wherein resin is complete porous tree of the aperture in 100~1000nm
Fat, haydite are porous ceramic grain of the grain size in 2~2.5cm.The action principle of second purifying layer 5 and the first purifying layer 3 are substantially
It is identical, but due to the second purifying layer 5 apart from ground farther out, form certain anaerobic environment, can be by anaerobe into one
In step purification water holding layer slowly under pollutant in the rainwater that oozes, the mainly TN in rainwater strengthens clean-up effect.
Connecting pipe in the present invention is made of inlet channel 7 and outlet conduit 12.The inlet channel 7 is located at water holding layer
4 bottoms, a diameter of 0.8~1cm of inner wall of the pipe so that it is to receive the water of overflow in upper level step building block and be discharged into next stage
In the storage cavity 6 of step building block.Outlet conduit 12 is located at the bottom of storage cavity 6, and inner diameter is 0.6~0.8cm, slightly carefully
In inlet channel 7, make it possible to be nested into next stage step and build in inlet channel 7 in the block, it can will be in storage cavity 6
Extra water is discharged into next stage step building block.
As shown in Fig. 2, the storage cavity 6 includes outer wall 8, the first cement being horizontally installed in the storage cavity 6
Water-stop sheet 9 and the second cement water-stop sheet 10 being disposed longitudinally in the storage cavity 6, the first cement water-stop sheet 9
Top is equipped with diversion trench 11.In the present invention, " transverse direction " refers to be orthogonal to the direction along step, and " longitudinal direction " refers to the side along step
To.Preferably, the cavity in the building block of upper level step between the first cement water-stop sheet 9 and outer wall 8 by outlet conduit 12 under
Inlet channel 7 is connected in level-one step building block.And the height of the storage cavity 6 is 6~10cm；The diversion trench 11
Groove depth is 1~2cm, and groove width is 3~5cm.
Upper strata can be purified the rainwater completed and stored by the storage cavity 6 of the present invention, when the rainwater of storage is high
After degree is more than the lower edge of the diversion trench 11, it will be fallen into due to gravitational difference in next stage step, until the step of bottommost, water
It is as shown in Figure 3 to flow direction A.First cement water-stop sheet 9 and the second cement water-stop sheet 10 can ensure all to store one in every grade of step
Divide rainwater.When encountering dry weather, the water in storage cavity 6 can evaporate upwards, improve region miniclimate, alleviate Urban Thermal
Island effect.And extra rainwater is downward step by step, until all storage cavities 6 all have been filled with rainwater, ensures that this step is collected
The effect of purifying rainwater system, extra rainwater can connect the pouring that greening pipe network carries out greenery patches as greening with water, save water
Resource.In addition storage rainwater in storage cavity 6, can also reduce runoff amount of rainfall, reduce and arrange rainwater outside region.
Place setting step building block be should also be step structure basis, can be used usual manner and according to actual conditions into
Row material selection and laying.The step building block of the present invention can refer to following steps and construct：
A. preparation of construction：Good material is done in prune job place, tool prepares；
B. according to design requirement unwrapping wire；
C. step base layer construction ensures step base fixed；
D. step building block is mated formation, it is ensured that the inlet channel of step building block and outlet conduit and the superior and the subordinate's step building block
It is nested against one another；
E. site clearing, conserve and come into operation.
