A waterproof strip 5153 made of rubber is inherently arranged on the inner periphery of the slot 5142, and the inner periphery of the waterproof strip 5153 is matched with the outer periphery of the inserted rod in shape. The height of the positioning rod 5141 is equal to that of the water purification unit 512, and the insert block 5143 is provided with the permeable geotextile 516 in a penetrating manner. The water-permeable geotextiles 516 are positioned by the inserting blocks 5143 and horizontally arranged between the water purification units 512 in different layers, and the water purification units 512 in different layers are spaced by the water-permeable geotextiles 516. When the positioning rod 5141 is manually inserted and removed by a user and the insert block 5143 is fitted into the slot 5142, the insert block 5143 is fixed in the slot 5142 by the magnetic attraction between the magnetic piece 5151 and the magnetic block 5152. The waterproof strip 5153 prevents moisture or water from contacting the magnetic sheet 5151 and the magnetic block 5152, reduces the possibility of rusting of the magnetic sheet 5151 and the magnetic block 5152 and influences the stability of the fixing of the inserting block 5143 and the inserting groove 5142, and has long service life.
Referring to fig. 1, in order to facilitate the user to monitor the water purification efficiency, flow meters 66 are disposed at the input end of the landscape tank 523 and the output end of the vertical flow subsurface purification bed 521. The bottom of the landscape pool 523 and the bottom of the vertical-flow subsurface-flow purification bed 521 are respectively provided with a permeable concrete area 67 and an impermeable concrete area 68, the permeable concrete area 67 and the impermeable concrete area 68 are arranged at intervals in a shape of a Chinese character 'hui', and the total area of the permeable concrete area 67 is one tenth of the total area of the impermeable concrete area 68. The flow meter 66 is convenient for users to determine the retention time of rainwater in the landscape tank 523 and the vertical-flow subsurface-flow purification bed 521, can be used for conveniently determining the instantaneous rainstorm capacity of the landscape tank 523 and the vertical-flow subsurface-flow purification bed 521 by matching with the water level meter 64, and can further change the ratio of the rainwater flow of the flow separation purification of the artificial wetland 52 and the water purification reservoir 51 through the flow control pump 65 and the control valve 63, so that the use is more convenient. The pervious concrete area 67 enables the landscape pool 523 and the vertical flow subsurface flow purification bed 521 to have larger instantaneous rainstorm capacity, and the effect of the sponge city is better.
Referring to fig. 5, in order to increase the rainwater collection efficiency during heavy rains, a plurality of square overflow ports 25 communicating with the drainage ditch 22 are provided at one side of the walking road 21, and the overflow ports 25 are arranged in a row along the longitudinal direction of the walking road 21. A filter screen 26 is detachably fixed at the top end of the overflow port 25 through a screw thread piece, a water storage block 24 is placed in the drainage ditch 22, and a pull rope 27 for mutual connection is arranged between the water storage block 24 and the filter screen 26. The water storage block 24 is made of a high polymer flexible water-absorbing material, and in the embodiment, melamine sponge is preferred. The water storage block 24 is arranged in a plate shape, the side length of the end surface shape of the water storage block 24 close to the pull rope 27 is smaller than that of the cross section shape of the overflow port 25, and the water storage block 24 can freely penetrate through the overflow port 25 through deformation and pulling of the pull rope 27. The filter screen 26 is embedded at the top end of the overflow port 25 and is detachably fixed by a screw.
When the water seepage rate of the rainstorm and water seepage bricks is not enough to meet the drainage requirement of the walking road 21, rainwater can enter the drainage ditch 22 from the overflow port 25, and the rainwater collection effect and the waterlogging prevention effect are better. The filter screen 26 can intercept garbage, and reduce the burden of subsequent rainwater purification. The water storage block 24 can temporarily store rainwater by absorbing the rainwater. After the rainfall stops, the water in the water storage block 24 is evaporated and radiated, so that the temperature of the walking road 21 can be reduced, the heat island effect of the city is reduced, and the comfort level of urban residents is improved. The convenient of water storage block 24 has been realized through stay cord 27 when filter screen 26 is convenient to be torn open the ann, and the person of facilitating the use changes water storage block 24, convenient to use after water storage block 24 material is ageing.
The implementation principle of the embodiment is as follows: the rainwater is purified by shunting the artificial wetland 52 and the water purification unit 512, when activated carbon in the water purification unit 512 is adsorbed and saturated, a user can replace the water purification unit 512 through the artificial wetland 52 without interrupting the purification treatment of the rainwater, meanwhile, the economic benefit of the system is increased through the aquatic plants of the artificial wetland 52, the environment beautifying effect of the system is enhanced, the lifting platform 513 is lifted and the positioning rod 5141 is conveniently detached and installed to improve the replacement efficiency when the water purification unit 512 is replaced, and the use is convenient.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
