[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 provides a drainage and pressure relief device that can effectively provide early warning of groundwater pressure, thereby solving the problem in the prior art of being unable to provide early warning of groundwater pressure.

[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] In the prior art, drainage structures are often installed in building basements, combined with pre-buried pipes to connect to groundwater for drainage. However, when drainage structures are used for drainage, new or existing buildings often use anti-floating reinforcement measures such as ballasting, anti-floating anchors, and anti-floating piles. These are passive anti-floating measures that often serve as emergency measures after problems occur and cannot provide early warnings, resulting in excessive groundwater pressure and reduced anti-floating effects on the entire building.

[0033] like Figure 1-Figure 3As shown, after research, by setting up a pressure test structure and using the pressure test structure to control the pressure relief execution structure, the flow of the circulation valve is timely adjusted according to the detected water pressure conditions, which solves the problem in the existing technology that there is no early warning of groundwater pressure, resulting in poor overall anti-floating effect of the building.

[0034] 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.

[0035] Example:

[0036] like Figure 1-Figure 2 As shown, a drainage and pressure relief device is installed in the basement of a building. The drainage and pressure relief device includes a pressure relief execution structure 20 and a pressure testing structure 23. The pressure relief execution structure 20 is connected to the basement of the building.

[0037] The pressure relief execution structure 20 includes a flow valve 21, a first flow guide pipe 201 and a second flow guide pipe 202. The first flow guide pipe 201 and the second flow guide pipe 202 are respectively installed at both ends of the flow valve 21. The flow valve 21 is used to control the flow of the first flow guide pipe 201 and the second flow guide pipe 202.

[0038] The pressure relief execution structure 20 is controlled by a controller, and the controller controls the flow valve 21 on the pressure relief execution structure 20 to open or close;

[0039] The end of the first flow guide pipe 201 away from the second flow guide pipe 202 is installed with a pre-buried pipe 121 and is connected to the pre-buried pipe 121;

[0040] The first flow guide pipe 201 is L-shaped and is connected to the basement of the building through the first support member 122 and the second support member 123;

[0041] The pressure testing structure 23 is installed on the first flow conduit 201 and is used to detect the water pressure in the first flow conduit 201 and send a detection signal to the controller, which controls the pressure relief execution structure 20 to regulate the water pressure.

[0042] By providing a pressure test structure 23 and utilizing the pressure test structure 23 to control the pressure relief execution structure 20, the flow rate of the circulation valve 21 is timely adjusted according to the detected water pressure condition, thereby solving the problem in the prior art of being unable to provide early warning of groundwater pressure, resulting in excessive groundwater pressure and a reduced expected anti-floating effect of the entire building.

[0043] The first flow guide pipe 201 is L-shaped, and the first support member 122 and the second support member 123 are used to support the first flow guide pipe 201. Specifically, the first support member 122 is L-shaped, and the side of the first support member 122 close to the first flow guide pipe 201 supports the horizontal pipe of the first flow guide pipe 201, and the side of the second support member 123 close to the first flow guide pipe 201 supports the vertical pipe of the first flow guide pipe 201, thereby improving the installation stability of the first flow guide pipe 201 and facilitating high-speed water flow through the first flow guide pipe 201 and the second flow guide pipe 202.

[0044] like Figure 1-Figure 3 As shown, the first flow guide pipe 201 is installed with the circulation valve 21 through the flange part 22, and the second flow guide pipe 202 is installed with the circulation valve 21 through the flange part 22. The first flange plate and the second flange plate on the flange part 22 are fixed by a screw, a first nut 225 and a second nut 226, and the second nut 226 is threadedly sleeved on the end of the screw.

[0045] When using the flange 22 for connection, first thread the second nut 226 onto the end of the screw, then pass the screw through the corresponding hole on the flange 22, and use the first nut 225 to install the flange 22 on the first and second flow guide tubes 201 and 202.

[0046] like Figure 2-Figure 3 As shown, a limiting ring 221 is provided on one side of the flange part 22, and a plurality of equally spaced protrusions 222 are provided on the side of the limiting ring 221 away from the flange part 22. A gasket 223 is installed between the first nut 225 and the limiting ring 221, and a groove 224 corresponding to the protrusion 222 is opened on the gasket 223. The gasket 223 is installed with the limiting ring 221 through the groove 224 and the protrusion 222.

[0047] By setting a protrusion 222 on the limiting ring 221 and opening a corresponding groove 224 on the gasket 223, the protrusion 222 and the groove 224 are installed with the limiting ring 221 to improve the stability of the gasket 223 during installation, making it easier for the first nut 225 to tighten the flange 22.

[0048] like Figure 2-Figure 3 As shown, the gasket 223 is sleeved on the screw, and the inner ring diameter of the gasket 223 is larger than the diameter of the screw, and the groove 224 is an inclined groove.

[0049] By setting the inner ring diameter of the gasket 223 to be larger than the diameter of the screw, the installation of the gasket 223 can be facilitated and the wear of the inner ring of the gasket 223 caused by the screw can be reduced. At the same time, the groove 224 is set as an inclined groove and corresponds one-to-one with the protrusion 222, which can further improve the stability of the gasket 223 installed on the limit ring 221.

[0050] Specifically, the limiting ring 221 is integrally formed with the first flange or the second flange on the flange member 22 .

[0051] like Figure 1 As shown, a sump is excavated in the basement of the building, and the sump is composed of a base layer 10, a waterproof layer 11 and a leveling layer 12. The waterproof layer 11 is located between the base layer 10 and the leveling layer 12, and the embedded pipe 121 is located between the waterproof layer 11 and the base layer 10. The end of the embedded pipe 121 away from the first guide pipe 201 is connected to the groundwater.

[0052] By setting up the sump in the form of a base layer 10, a waterproof layer 11 and a leveling layer 12, and setting the embedded pipe 121 between the waterproof layer 11 and the base layer 10, the water collected in the sump in the basement of the building can be connected to the groundwater to perform drainage operations in the sump.

[0053] Specifically, the drainage and pressure relief equipment is installed in the sump or on the floating plate used in the building. The entire drainage and pressure relief equipment is automatically controlled by CNC. In actual application, in order to ensure the safety of drainage and pressure relief on the site and avoid the backflow of pressure relief water into the basement, a two-level pressure standard is designed:

[0054] The first level is the warning pressure, which is temporarily set at 15kPa and will be adjusted later based on the actual situation on site. When the groundwater reaches the warning pressure, drainage and pressure relief will be automatically started and linked with the drainage and pressure relief equipment. If the pressure relief water in the pit cannot be pumped out smoothly, the drainage channel should be closed to prevent the pressure relief water from backflowing.

[0055] The second level is the safety pressure. When the groundwater reaches the safety pressure, drainage and pressure relief are forced to start to ensure the safety of the structure. The safety pressure is set according to the actual situation.

[0056] In summary, compared with the existing technology, the present invention has the following beneficial effects:

[0057] 1. By setting up a pressure test structure 23 and using the pressure test structure 23 to control the pressure relief execution structure 20, the flow of the circulation valve 21 is timely adjusted according to the detected water pressure condition, thereby solving the problem in the prior art of being unable to warn of groundwater pressure in advance, resulting in excessive groundwater pressure and a low expected anti-floating effect of the entire building;

[0058] The first flow guide pipe 201 is L-shaped, and the first support member 122 and the second support member 123 are used to support the first flow guide pipe 201. Specifically, the first support member 122 is L-shaped, and the side of the first support member 122 close to the first flow guide pipe 201 supports the horizontal pipe of the first flow guide pipe 201, and the side of the second support member 123 close to the first flow guide pipe 201 supports the vertical pipe of the first flow guide pipe 201, thereby improving the installation stability of the first flow guide pipe 201 and facilitating high-speed water flow through the first flow guide pipe 201 and the second flow guide pipe 202.

[0059] 2. By setting a protrusion 222 on the limiting ring 221 and opening a corresponding groove 224 on the gasket 223, the protrusion 222 and the groove 224 are installed with the limiting ring 221 to improve the stability of the gasket 223 during installation, making it easier for the first nut 225 to tighten the flange 22.

[0060] 3. By setting the inner ring diameter of the gasket 223 to be larger than the diameter of the screw, the installation of the gasket 223 can be facilitated and the wear of the screw on the inner ring of the gasket 223 can be reduced. At the same time, the groove 224 is set as an inclined groove and corresponds one-to-one with the protrusion 222, which can further improve the stability of the gasket 223 installed on the limit ring 221.
