The backflow prevention member 2 is communicated with the sump, and the backflow prevention member 2 is located above the sump.
[0026] It is understandable that the drainage groove member 1 can be arranged in the buffer room floor 3, and the drainage groove member 1 is attached to the insulation board 4 for discharging the accumulated water in the buffer room floor 3. The anti-backflow member 2 can prevent the water vapor and peculiar smell in the sump from rising into the cold storage space where the buffer room floor 3 is located.

[0028] It is understandable that the drain pipe 201 and the water seal bend pipe 202 can be of an integral structure. The water seal bend pipe 202 can retain part of the accumulated water to form a water seal, and the stop valve 203 can control the opening and closing of the anti-backflow member 2. The two cooperate to well prevent the water vapor and peculiar smell in the sump from rising into the cold storage space where the buffer room floor 3 is located.
[0029] Please continue to refer to Figure 1 , in some embodiments, the water seal bend pipe 202 includes at least two arc segments, and the two arc segments are communicated with each other to form an inverted S shape, and the two arc segments are respectively connected to a drain pipe 201.
[0030] It can be known that the two arc segments can be in a centrally symmetric form, and the arc segment and the corresponding drain pipe can be of an integral structure. The water seal bend pipe 202 of this structure can well store water to form a water seal.
[0031] Please refer to Figure 1 , in some embodiments, the drainage groove member 1 includes a cover plate 105, a trench 101 and a first drainage ditch 104. The cover plate 105 covers the trench 101, the trench 101 is communicated with the first drainage ditch 104, and the trench 101 is located above the first drainage ditch 104. The first drainage ditch 104 is communicated with the sump through the anti-backflow member 2.
[0032] It is understandable that the cover plate 105 can be of a metal mesh plate structure and can be made of stainless steel or aluminum materials. The accumulated water flows into the trench 101 through the cover plate 105, and then flows into the first drainage ditch 104 through the trench 101. The first drainage ditch 104 discharges the accumulated water into the sump through the anti-backflow member 2. The anti-backflow member 2 can be located in the sump, and JS waterproofing can also be done in the trench 101, that is, JS (polymer cement-based) waterproof coating is applied to the inner wall of the trench. The thickness of the JS waterproof coating can be 0.5 mm.
[0033] Please refer to Figure 1 In some embodiments, the drainage groove member 1 further includes a first filler 102 and a connecting pipe 103.

[0034] It can be understood that the first filler 102 can be foamed with black and white materials, the connecting pipe 103 can be embedded in the black and white material foam, the connecting pipe 103 can be a DN50 galvanized drainage pipe, and the first filler 102 can be used as a heat and gas insulation layer, that is, it can well reduce the heat and gas rising from the sump to the area where the buffer room floor 3 is located. The first drainage ditch 104 can be composed of an inverted U-shaped folding member and a stainless steel plate. The stainless steel plate is connected to the upper end of the inverted U-shaped folding member, and the stainless steel plate communicates with the connecting pipe 103.

[0037] The drainage groove member 1 includes a low wall 101a, an arc cover 101b and a second drainage ditch 101d. The arc cover 101b covers the entrance of the second drainage ditch 101d. The low wall 101a is located on the concave side of the arc cover 101b. The second drainage ditch 101d communicates with the sump through an anti-backflow member 2.
[0038] It can be understood that the low wall 101a can be selected to be made of reinforced concrete structure to provide higher strength and durability. The wall height of the low wall 101a is 300 mm, and the surface is covered with 0.5 mm thick waterproof coating. On the one hand, the low wall 101a can prevent collision with the insulation board 4, and on the other hand, it can also prevent external accumulated water from invading the indoor floor area inside the insulation board 4. The arc cover 101b cooperates with the low wall 101a to drain the accumulated water to the entrance of the second drainage ditch 101d. The arc cover 101b can be provided with a liquid discharge port, and the edge of the arc cover 101b can also be covered with SBS waterproof coiled material to improve the sealing performance with the insulation board 4. The accumulated water enters the second drainage ditch 101d through the arc cover 101b, and the accumulated water in the second drainage ditch 101d flows into the sump through the anti-backflow member 2. The upper part of the second drainage ditch 101d can be filled with black and white material foam, and a drainage pipe can be embedded in the black and white material foam. The drainage pipe can drain the accumulated water to the bottom of the second drainage ditch 101d. The bottom of the second drainage ditch 101d can be designed with reference to the structure of the first drainage ditch 104, and the inner wall of the second drainage ditch 101d can also be waterproofed with reference to the above.
[0039] Embodiment Three
[0040] Please refer to Figure 1 and Figure 2 , this embodiment provides a cold storage floor assembly, which includes the above-mentioned cold storage floor drainage structure, and also includes a thermal insulation board 4, an in-store floor 6 and a buffer room floor 3. The in-store floor 6 and the buffer room floor 3 are located on both sides of the thermal insulation board 4, and the drainage trench member 1 is located at the position of the buffer room floor 3.
[0041] It can be understood that the in-store floor 6 and the buffer room floor 3 are respectively located on both sides of the thermal insulation board 4. The in-store floor 6 can be located in the in-store area, the buffer room floor 3 can be located in the out-of-store area, and the drainage trench member 1 can be located in the buffer room floor 3.
[0042] Please refer to Figure 1 , in some embodiments, the in-store floor includes an in-situ floor 601, a heating pipe layer 602, a slope-forming layer 603, a first moisture-proof layer 604, a plurality of insulation layers 605, a second moisture-proof layer 606, a leveling layer 607, a concrete layer 608 and a wear-resistant floor layer 609, which are arranged in sequence from bottom to top. The in-situ floor 601, the heating pipe layer 602, the slope-forming layer 603, the first moisture-proof layer 604, the second moisture-proof layer 606, the leveling layer 607, the concrete layer 608 and the wear-resistant floor layer 609 are all adhesively connected to the thermal insulation board 4. The water separation groove 611 is arranged on the wear-resistant floor layer 609. The plurality of insulation layers 605 are arranged in parallel and offset to form a filling space with the thermal insulation board 4, and the filling space is filled with a foaming layer 610 so that the insulation layer 605 is adhesively connected to the thermal insulation board 4.
[0043] It can be understood that the heating pipe layer 602 can be a C20 fine aggregate concrete layer with a thickness of 100 mm, in which floor heating pipes can be pre-embedded. The floor heating pipes can be HDPE ethylene glycol anti-freezing and swelling heating pipes. The slope-forming layer 603 can be a C20 fine aggregate concrete layer with a thickness of 80 to 100 mm, in which HDPE ethylene glycol anti-freezing and swelling heating pipes can also be pre-embedded. The first moisture-proof layer 604 can be an SBS waterproof asphalt flexible coil layer. The first moisture-proof layer 604 and the adjacent insulation layer 605 can also be arranged in a staggered manner. The insulation layer 605 can be an XPS extruded insulation board. The overall thickness of several insulation layers 605 can be 250 mm. The insulation layers 605 can be arranged in parallel and staggered, that is, the distances between the ends of the insulation layers 605 and the insulation board 4 are inconsistent. Therefore, a filling space will be formed between several insulation layers 605 and the insulation board 4. The foaming layer 610 filled in the filling space can be a polyurethane foaming layer. The filling space can be formed by enclosing the insulation layer 605, the insulation board 4, the second moisture-proof layer 606 and the slope-forming layer 603. The second moisture-proof layer 606 can also be an SBS waterproof asphalt flexible coil layer. The leveling layer 607 can be a C40 fine aggregate concrete layer with a thickness of 50 to 70 mm. The concrete layer 608 can be a C40 concrete layer with a thickness of 250 mm, in which double-layer and double-directional steel bars ∅14@150 plus steel fibers of 15 kg / m2 can be tied. The wear-resistant floor layer 609 can be a floor with diamond abrasion resistance, polished with a surface penetration curing agent. The wear-resistant floor layer 609 can be selected to be set or not according to actual needs. When applied in the first embodiment, the insulation board 4 can be placed on the slope-forming layer 603. In the second embodiment, a concrete wall 7 can be built on the original floor 601. The upper end surface of the concrete wall 7 can be flush with the upper end surface of the slope-forming layer 603, and the insulation board 4 is placed on the concrete wall 7.
[0044] Please continue to refer to Figure 1 and Figure 3 , in some embodiments, the interior floor 6 of the warehouse further includes a flow guide plate 5. Correspondingly, a water separation groove 611 is provided on the interior floor 6 of the warehouse. The flow guide plate 5 has ductility and is used to connect the insulation board 4 and the water separation groove 611. The flow guide plate 5 can include a fitting section 501, a flow guiding section 502 and a connecting section 503. The fitting section 501 is connected to the connecting section 503 through the flow guiding section 502. The fitting section 501 is used to fit and connect the insulation board 4. The flow guiding section 502 has ductility and is used to guide the water flow into the water separation groove 611. The connecting section 503 is used to fit and connect in the water separation groove 611. The flow guiding section 502 includes an end portion and a middle portion. The end portions are located at both ends of the middle portion, and the end portions are respectively connected to the fitting section 501 and the connecting section 503. The middle portion deviates towards the direction where the insulation board 4 is located, so that the flow guiding section 502 is in an arc shape, and the middle portion has ductility.
[0045] It is understandable that the fitting section 501 can be parallel to the thermal insulation board 4, the connecting section 503 can be parallel to the vertical wall surface of the water separation tank 611. The fitting section 501, the diversion section 502 and the connecting section 503 can be of an integral structure, and the fitting section 501, the diversion section 502 and the connecting section 503 can all be made of metal materials, such as 304 or 316 stainless steel, so they have certain ductility, thus better adapting to the environment in the storage. The fitting section 501 can be bonded to the thermal insulation board 4, and the bonding method can be bonding to the thermal insulation board 4 through polyurethane low-temperature sealant. The diversion section 502 can divert the condensed water flowing down from the thermal insulation board 4 to the water separation tank 611, thus preventing the condensed water from flowing into the gap at the connection between the thermal insulation board 4 and the floor main body. The water separation tank 611 can discharge the condensed water. The connecting section 503 can well improve the connection effect between the diversion section 502 and the water separation tank 611. Due to the low temperature in the storage, the connecting section can prevent the diversion section from detaching from the water separation tank 611 under the action of the principle of cold shrinkage. The connecting section 503 can be embedded into the water separation tank 611. Therefore, the connecting section 503 can be bonded in the water separation tank 611 or not. If bonded, polyurethane low-temperature sealant can also be used. The lengths of the above-mentioned fitting section 501 and connecting section 503 can be two centimeters. The size of the water separation tank 611 needs to be set according to the height of the cold storage. The higher the height of the thermal insulation board 4 of the cold storage, the larger the water separation tank 611 to be set. In this embodiment, the depth of the water separation tank 611 is 3-5 centimeters and the width is 5-10 centimeters.
[0046] From the above description, it can be known that the cold storage floor drainage structure and the cold storage floor assembly provided by the present invention can prevent water vapor and peculiar smell from flowing back into the cold storage space through the anti-backflow member 2, thus not affecting the working environment in the cold storage.
[0047] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
