[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] The embodiment of the present application solves the problem in the prior art that accumulated water containing impurities is directly connected to groundwater by providing an external drainage device, thereby facilitating the discharge of accumulated water in the sump.

[0031] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0032] like Figure 1-Figure 2As shown, by setting the external drainage device in the form of a first water pipe and a second water pipe, and embedding a filter element inside the first water pipe, the filter element is used to filter the accumulated water introduced into the sump, which solves the problems of the existing technology that, during the drainage process, the accumulated water in the sump containing impurities is directly connected to the groundwater, resulting in groundwater pollution, and the accumulated water containing impurities is directly discharged for a long time during the drainage process, resulting in groundwater stagnation and inability to discharge the accumulated water in time, causing the groundwater pressure to be too high and the anti-floating effect of the building to be poor.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] Example:

[0035] like Figure 1 As shown, a drainage external device is buried under the ground consisting of a base layer 10, a waterproof layer 11 and a leveling layer 12, wherein the waterproof layer 11 is located between the base layer 10 and the leveling layer 12, and the leveling layer 12 is located above the waterproof layer 11;

[0036] The external drainage device includes a first water pipe 21 and a second water pipe 22 arranged below the first water pipe 21. The waterproof layer 11 is provided with a first installation groove 121. The first water pipe 21 is embedded in the first installation groove 121. The second water pipe 22 passes through the foundation layer 10 and communicates with the groundwater.

[0037] The first water conduit 21 is connected to the waterproof layer 11 via a mounting member 213;

[0038] The inner diameter of the first water pipe 21 is larger than the inner diameter of the second water pipe 22. A filter element 211 is embedded in the first water pipe 21. The outer diameter of the filter element 211 matches the inner diameter of the first water pipe 21.

[0039] A drainage pipe 20 is laid between the waterproof layer 11 and the leveling layer 12. The end of the drainage pipe 20 close to the first water conduit 21 is connected to the first water conduit 21 through a connecting pipe 212. The end of the drainage pipe 20 away from the first water conduit 21 is connected to a sump. A control valve is installed in the sump to control the drainage of the drainage pipe 20.

[0040] The connecting pipe 212 and the water outlet near one end of the first water pipe 21 are located above the filter element 211 .

[0041] By setting up the external drainage device in the form of a first water pipe 21 and a second water pipe 22, and embedding a filter element 211 inside the first water pipe 21, the filter element 211 is used to filter the accumulated water introduced into the sump, which solves the problem of the existing technology that, during the drainage process, the accumulated water in the sump containing impurities is directly connected to the groundwater, causing groundwater pollution, and the direct discharge of the accumulated water containing impurities for a long time, resulting in the groundwater not circulating, and the inability to discharge the accumulated water in time, resulting in excessive groundwater pressure and poor anti-floating effect of the building.

[0042] When setting the first water pipe 21 and the second water pipe 22, the diameter of the first water pipe 21 is set larger than the diameter of the second water pipe 22. The second water pipe 22 is used to support the filter element 211 to prevent the filter element 211 from moving inside the first water pipe 21, thereby facilitating the filter element 211 to filter out impurities in the accumulated water.

[0043] Specifically, the first water pipe 21 and the second water pipe 22 are detachably connected, thereby facilitating the cleaning and replacement of the filter element 211 in the first water pipe 21 .

[0044] The mounting member 213 includes an upper mounting plate and a lower mounting plate. The upper mounting plate is mounted on the inner wall of the first mounting groove 121, and the lower mounting plate is mounted on the end of the first water pipe 21 away from the second water pipe 22. The upper mounting plate and the lower mounting plate are connected by anchor bolts to realize the installation operation of the first water pipe 21.

[0045] A mounting ring 214 is fixedly provided on the outer surface of the first water pipe 21. During installation, the mounting ring 214 is located in the first mounting groove 121 and abuts against the waterproof layer 11. By providing the mounting ring 214, the installation of the first water pipe 21 can be limited, thereby further improving the stability of the installation of the first water pipe 21.

[0046] like Figure 1-Figure 2 As shown, a second mounting groove 122 is opened on the leveling layer 12, and the second mounting groove 122 and the first mounting groove 121 are connected. A manhole cover 30 is installed in the second mounting groove 122, and the manhole cover 30 includes a frame 31 and multiple reinforcing ribs 32, and the multiple reinforcing ribs 32 cross in the frame 31 to form multiple picking and placing grooves 321.

[0047] The provision of the taking-and-placing groove 321 makes it easier to take the manhole cover 30 .

[0048] Specifically, such as Figure 2 As shown, lining plates 33 are respectively provided in the pick-and-place slots 321 at the corners, and notches 331 are formed between the lining plates 33 and the frame 31 and the corresponding reinforcing ribs 32 . Mounting holes 332 are opened on the lining plates 33 .

[0049] During installation, bolts are installed in the mounting holes 332, and the bolts are used to install the manhole cover 30 on the ground. By setting the lining plate 33, a slot 331 is formed between the lining plate 33, the frame 31 and the corresponding reinforcing rib 32. The bolts installed in the mounting holes 332 are located inside the slot 331. The setting of the slot 331 can maintain the flatness of the surface of the manhole cover 30. At the same time, it can effectively prevent the bolts from falling into the first mounting slot 121 through the pick-up and placement slot 321 during installation, resulting in low installation efficiency.

[0050] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0051] 1. By setting the external drainage device in the form of a first water pipe 21 and a second water pipe 22, and embedding a filter element 211 inside the first water pipe 21, the filter element 211 is used to filter the accumulated water introduced into the sump, which solves the problem of the existing technology that, during the drainage process, the accumulated water in the sump containing impurities is directly connected to the groundwater, causing groundwater pollution, and the direct discharge of the accumulated water containing impurities for a long time, resulting in the groundwater not circulating, and the inability to discharge the accumulated water in time, resulting in excessive groundwater pressure and poor anti-floating effect of the building.

[0052] 2. When setting the first water pipe 21 and the second water pipe 22, the diameter of the first water pipe 21 is set larger than the diameter of the second water pipe 22. The second water pipe 22 is used to support the filter element 211 to prevent the filter element 211 from moving inside the first water pipe 21, so that the filter element 211 can filter out impurities in the accumulated water. The first water pipe 21 and the second water pipe 22 are detachably connected, so as to facilitate the cleaning and replacement of the filter element 211 in the first water pipe 21.

[0053] 3. By setting a lining plate 33, a slot 331 is formed between the lining plate 33, the frame 31 and the corresponding reinforcing rib 32. The bolt installed in the mounting hole 332 is located inside the slot 331. The setting of the slot 331 can maintain the flatness of the surface of the manhole cover 30. At the same time, it can effectively prevent the bolt from falling into the first mounting slot 121 through the pick-up and placement slot 321 during bolt installation, resulting in low installation efficiency.
