[0002] As my country's urbanization level increases and its economy continues to develop, people's demand for a better life is getting higher and higher. Urban green coverage rate and per capita sports venue area are important indicators for improving people's needs for a better life. Nowadays, there is less and less land available for development in cities. In urban areas where every inch of land is valuable, it has become a trend to develop greening and sports venues in the air. The construction of aerial greening and sports venues can greatly increase the urban green coverage rate and per capita sports venue area, and achieve three-dimensional and healthy development of urban greening and sports venue construction.

[0003] At present, the existing sky garden drainage technology is a rigid drainage structure layer, which is only suitable for some sky gardens without floating loads. However, in sky football fields, sky leisure lawns and other sky gardens with floating loads, once the rigid drainage structure is structurally damaged or blocked, it is difficult to repair. Summary of the invention

In addition, the floor structure of the present invention has the six functional effects of "seepage, retention, storage, purification, use, and drainage" of the sponge concept.

[0007] To solve the above-mentioned first technical problem, the present invention adopts the following technical solution:

[0010] The drainage structure layer includes a first ceramsite layer, a first geotextile, a second ceramsite layer, a second geotextile, and light planting soil arranged in sequence from bottom to top, and a lawn is planted on the light planting soil;

[0011] The drainage device is arranged between the first ceramsite layer and the second protective layer. The drainage device is connected with a nozzle. The nozzle is placed above the lawn and is used for spraying the water collected by the drainage device onto the lawn.

[0012] Furthermore, the inner side of the wall is sequentially paved with a fourth protective layer, a third anti-seepage layer, and a third protective layer from the outside to the inside.

[0013] Furthermore, the drainage device includes a detachable drainage pipe and a water tank, the detachable drainage pipe is pre-applied between the first expanded clay layer and the second protective layer; the water tank and the detachable drainage pipe are connected by a first water pipe, a water pump for pumping water to the nozzle is arranged in the water tank, and the water pump and the nozzle are connected by a second water pipe.

[0014] Furthermore, the drainage device also includes a drain pipe protection cover for preventing expanded clay from entering the detachable drain pipe; the drain pipe protection cover is a hollow cylindrical shape, the front half of the drain pipe protection cover is provided with an internal thread, and the rear half is arranged in a lattice shape; the water inlet end of the detachable drain pipe is provided with an external thread, and the drain pipe protection cover and the detachable drain pipe are detachably connected via threads.

[0015] Furthermore, the water inlet port of the detachable drain pipe is set to a 45° oblique opening, and a filter screen is provided at the oblique opening.

[0016] Furthermore, the first anti-seepage layer, the second anti-seepage layer and the third anti-seepage layer are all made of elastomer-modified asphalt waterproof membrane.

[0017] Furthermore, the first protective layer, the fifth protective layer and the sixth protective layer are made of polymer cement waterproof mortar, and the second protective layer, the third protective layer and the fourth protective layer are made of fine stone concrete.

[0018] Preferably, the ceramsite layer is made of bauxite ceramsite sand having the characteristics of high strength, strong flow conductivity and corrosion resistance.

[0019] To solve the above second technical problem, the technical solution adopted by the present invention is:

[0020] A construction method for a floor structure capable of adapting to floating loads and having a sponge function, comprising the following steps:

[0021] (1) Building walls around the floor decking;

[0022] (2) Laying the fourth protective layer, the third anti-seepage layer, and the third protective layer on the inner side of the wall from the outside to the inside;

[0023] (3) Lay a leveling layer on the floor decking, and then lay a bonding layer on the leveling layer;

[0024] (4) Apply waterproof coating to the laid bonding layer, and then lay the first anti-seepage layer on this basis;

[0025] (5) Laying the first protective layer on the laid first anti-seepage layer, applying waterproof coating on the laid first protective layer, and laying the second anti-seepage layer on this basis;

[0026] (6) Laying a second protective layer on the laid second anti-seepage layer;

[0027] (7) filling the first ceramsite layer on the second protective layer, and arranging a drainage device between the second protective layer and the first ceramsite layer;

[0028] (8) laying a first geotextile on the first ceramsite layer;

[0029] (9) filling a second ceramsite layer on the first geotextile;

[0030] (10) laying a second geotextile on the second ceramsite layer;

[0031] (11) Fill the second geotextile with lightweight planting soil, and finally plant lawn on the lightweight planting soil.

[0032] Furthermore, the drainage device comprises a drainage pipe protective cover, a detachable drainage pipe and a water storage tank. In step (1), the drainage pipe protective cover is pre-applied to one side of the wall during the construction process and is located between the second protective layer and the first expanded clay layer. The surface of the second protective layer presents a 2% slope, so that the relative elevation of the side of the second protective layer close to the detachable drainage pipe is lower than that of other positions, so that water falling on the second protective layer can be collected on the side where the detachable drainage pipe is located; the detachable drainage pipe is detachably connected to the drainage pipe protective cover, the detachable drainage pipe is connected to the water storage tank through a first water pipe, a water pump is arranged in the water storage tank, the water pump is connected to the second water pipe, a nozzle is installed at the other end of the second water pipe, and the nozzle is arranged above the lawn.

[0033] By adopting the above technical solution, a waterproof structure layer is laid on the floor deck, and a double waterproof membrane layer and a double protective layer are staggered on the plane to achieve flat waterproofing. A double protective layer and a layer of waterproof membrane layer are laid on the facade to form a "barrel"-shaped waterproof structure, and the drainage structure layer is wrapped in the waterproof structure layer;

[0034] A staggered double-layer ceramsite and double-layer geotextile are laid on the second protective layer in the waterproof structure layer. The ceramsite layer and the geotextile will not cause irreversible damage to the drainage structure due to the upper load, and the ceramsite and the geotextile are separated and easy to repair. Therefore, compared with the traditional rigid drainage structure which is hard and difficult to change, and once changed, it is irreversible, the drainage structure layer of the present invention fully embodies the characteristic of "flexibility";

[0035] A drainage pipe protective cover is pre-applied on the waterproof layer wall at the first expanded clay layer in the drainage structure layer, and a detachable drainage pipe and a first water pipe are installed and connected in sequence. This part can discharge the rainwater collected by the drainage structure layer into a water storage tank to collect the rainwater. A water pump is installed inside the water storage tank to pump out the rainwater through the water pump and reach the sprinkler through the second water pipe to spray the lawn.

[0036] The "barrel"-shaped waterproof structure and "flexible" drainage structure realized by the above technical solution embody the construction method of the present invention based on the sponge concept; among them, the present invention realizes the characteristic of water seepage by using geotextile with specific water seepage function and ceramsite granular filling.

[0037] At the same time, compared with the rigid drainage structure in the prior art, which uses drainage boards and hollow drainage inside drainage pipes, the present invention is not conducive to delaying rainwater. The present invention uses a staggered layered combination structure filled with geotextiles and expanded clay particles. The expanded clay layer filling structure, irregular gaps and unevenly distributed holes relatively delay the discharge of rainwater, reflecting the characteristics of delaying rainwater drainage.

[0038] As mentioned above, the outer periphery of the drainage structure layer is wrapped by a "barrel"-shaped waterproof layer, and rainwater can only be discharged through the only channel of the detachable drainage pipe. Its structural form has the characteristics of gathering rainwater and preventing rainwater from being discharged irregularly, and the rainwater discharged from the detachable drainage pipe flows into the water storage tank through the first water pipe for storage and recycling.

[0039] Rainwater that penetrates through the drainage structure layer can only flow out through the detachable drainage pipe. The detachable drainage pipe is connected to the first water pipe and discharged to the designated water storage tank. The storage and discharge structure of the present invention can drain rainwater to a designated location, reflecting its characteristic of controllable rainwater discharge.

[0040] In addition, the expanded clay in the expanded clay layer has the function of absorbing harmful elements and bacteria in the water body and mineralizing water quality. It is a filter material with very good effect of active biological degradation of harmful substances and the best biofilm carrier in the biological filter tank, which reflects the characteristic of the present invention that it can purify rainwater.

[0041] When performing daily maintenance on the lawn, the water pump in the water tank can be started to pump the stored rainwater out of the water tank, and then reach the sprinkler head through the second water pipe. The sprinkler head sprays the lawn, thus embodying the feature of rainwater collection and utilization.

[0042] In summary, the synergistic effect between the various structural layers of the present invention makes the overall technical effect of the present invention consistent with the concept of "seepage, retention, storage, purification, use and discharge" in the sponge concept, and can make better use of water resources.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] (1) The floor structure provided by the present invention can adapt to floating loads and has sponge functions. Its drainage structure layer is a flexible structure, so that its structure can adapt to floors of different shapes and structures, has strong applicability, low repair difficulty, simple structure, simple construction process and low cost.

[0045] (2) The structural characteristics of the waterproof structure layer and the drainage structure layer of the present invention conform to the sponge concept of "seepage, retention, storage, purification, use, and drainage", and adapt to the trend of the times in the construction of modern urban sponge cities.

DETAILED DESCRIPTION

[0051] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can better understand and implement the technical solution of the present invention.

[0052] The present invention provides a floor structure that can adapt to floating loads and has a sponge function, including a floor deck 1, a waterproof structure layer and a drainage structure layer, wherein the waterproof structure layer is laid on the floor deck 1, the drainage structure layer is laid on the waterproof structure layer, a drainage device is arranged between the waterproof structure layer and the drainage structure layer, a wall 16 is built on the floor deck 1 around the drainage structure layer, the waterproof structure layer and the light planting soil 12, and at least one protective layer is laid on the inner side of the wall 16; in the present invention, a "barrel"-shaped waterproof structure is formed between the waterproof structure layer below the drainage structure layer and the protective layer laid on the inner side of the wall 16, and the drainage structure layer is wrapped therein, rainwater can only be discharged through the only channel of the detachable drainage pipe, and the structural form has the characteristics of gathering rainwater and preventing rainwater from being discharged irregularly;

[0053] like Figure 1 As shown, the waterproof structure layer includes a leveling layer 2, a bonding layer 3, a first anti-seepage layer 4, a first protective layer 5, a second anti-seepage layer 6, and a second protective layer 7 which are arranged in sequence from bottom to top;

[0054] The drainage structure layer includes a first ceramsite layer 8, a first geotextile 9, a second ceramsite layer 10, a second geotextile 11, and a light planting soil 12 arranged in sequence from bottom to top, and a lawn 15 is planted on the light planting soil 12;

[0055] The protective layer inside the wall 16 includes a fourth protective layer 18, a third anti-seepage layer 19, and a third protective layer 17 which are laid sequentially from the outside to the inside;

[0056] The drainage device includes a drainage pipe protective cover 13, a detachable drainage pipe 14 and a water tank 21. The drainage pipe protective cover 13 is pre-applied on the wall 16 and is located between the first expanded clay layer 8 and the second protective layer 7. The drainage pipe protective cover 13 is detachably connected to the detachable drainage pipe 14; the water tank 21 is connected to the detachable drainage pipe 14 through a first water pipe 20, and a water pump 22 for pumping water to the nozzle 24 is arranged in the water tank 21, and the water pump 22 is connected to the nozzle 24 through a second water pipe 23.

[0057] In order to enable rainwater that penetrates the second protective layer 7 to be gathered in the detachable drain pipe 14 in large quantities, the second protective layer 7 is sloped at 2% so that the relative elevation of the side close to the detachable drain pipe 14 is lower than that of other positions.

[0058] In the present invention, the drain pipe protection cover 13 is a hollow cylinder, the front half of the drain pipe protection cover 13 is provided with an internal thread, and the rear half is arranged in a lattice shape; the water inlet end of the detachable drain pipe 14 is provided with an external thread, and the drain pipe protection cover 13 and the detachable drain pipe 14 are detachably connected through threads; the function of the drain pipe protection cover 13 is to protect the detachable drain pipe 14 and prevent the expanded clay in the first expanded clay layer 8 from pressing down the detachable drain pipe 14 under the action of gravity, and at the same time, the lattice in the rear half of the drain pipe protection cover 13 can block the expanded clay.

[0059] In addition, the water inlet port of the detachable drain pipe 14 is set to a 45° bevel, and a filter net is provided at the bevel. The gap of the filter net is much smaller than the size of a single expanded clay, which can further prevent the expanded clay from clogging the drain pipe. Compared with the flat pipe mouth, the 45° bevel design on the detachable drain pipe 14 increases the water inlet area and filters smaller objects.

[0060] When it rains, rainwater infiltrates from the lightweight planting soil 12, passes through the second geotextile 11, the second ceramsite layer 10, the first geotextile 9, and the first ceramsite layer 8 in sequence, and then infiltrates to the second protective layer 7 at the bottom of the first ceramsite layer 8. Since the second protective layer 7 is set with a 2% slope, the rainwater will gather in large quantities at the detachable drainage pipe 14 after falling on the second protective layer 7, and then flow out from the detachable drainage pipe 14, and finally reach the water storage tank 21 through the first water pipe 20, and then the water pump 22 inside the water storage tank 21 is started to supply the stored rainwater to the sprinkler 24 through the second water pipe 23 to spray the lawn 15;

[0061] Even if a small amount of rainwater cannot be discharged from the drain pipe, since the leveling layer 2, the bonding layer 3, the first anti-seepage layer 4, the first protective layer 5 and the second anti-seepage layer 6 are laid under the second protective layer 7, it is possible to prevent rainwater from seeping into the floor decking.

[0062] The first anti-seepage layer 4, the second anti-seepage layer 6 and the third anti-seepage layer 19 are all made of elastomer-modified asphalt waterproofing membrane.

[0063] The first protective layer 5 and the fourth protective layer 18 are made of polymer cement waterproof mortar, and the second protective layer 7 and the third protective layer 17 are made of fine stone concrete.
