Description

Technical Field

[0001] This utility model relates to the field of basement vacuum drainage technology, and in particular to an active anti-buoyancy basement vacuum drainage device. Background Technology

[0002] Construction in high-water-level areas often presents challenges such as high groundwater levels, high water head pressure, and significant seasonal fluctuations in groundwater levels. In these conditions, the basement floor slab of the building will bear immense buoyancy. Traditional construction methods typically employ passive anti-buoyancy techniques such as anti-buoyancy anchors and anti-uplift piles to mitigate the destructive force of buoyancy on the floor slab. However, these methods suffer from high construction costs, long implementation periods, and poor anti-buoyancy capabilities. Therefore, an active anti-buoyancy technology has been proposed, which uses drainage and pressure relief to weaken the buoyancy force on the floor slab, thereby achieving the goal of anti-buoyancy.

[0003] Existing basement floor slabs require a large number of anti-buoyancy anchors and anti-uplift piles for anti-buoyancy purposes, resulting in high costs. Furthermore, when the water flow rises rapidly, it can easily lead to overload damage to the anti-buoyancy components, such as anchor breakage and pile deformation. Therefore, we propose an active anti-buoyancy basement vacuum drainage device. Utility Model Content

[0030] The basement vacuum anti-buoyancy pumping assembly 1 includes a sand discharge pipe 11, a water collection pipe 12, a filter screen 13, a vacuum main pipe 14, a vacuum branch pipe 15, and a one-way valve 16. The sand discharge pipe 11 is fixedly installed inside the water collection well 4, the water collection pipe 12 is fixedly installed inside the sand discharge pipe 11, the filter screen 13 is fixedly installed inside the sand discharge pipe 11 and the water collection pipe 12, the vacuum main pipe 14 is fixedly installed on one side of the vacuum pump 5 and is connected to the vacuum pump 5, one end of the vacuum branch pipe 15 is fixedly installed inside the vacuum main pipe 14, the one-way valve 16 is fixedly installed outside the vacuum branch pipe 15, and the other end of the vacuum branch pipe 15 is fixedly installed inside the water collection well 4.

[0031] In this embodiment, a vacuum pressure gauge 7 is fixedly installed on one side of the vacuum pump 5, and a basement vacuum drainage flushing anti-clogging component 2 is installed on the basement floor structure 3 and the drainage box 6.

[0032] In this embodiment, the basement vacuum anti-buoyancy pumping assembly 1 also includes a pumping pump 17, a pumping pipe 18, a branch flow pipe 19, and a main drainage pipe 20. The pumping pump 17 is fixedly installed on the bottom inner wall of the sump 4, the pumping pipe 18 is fixedly installed at the input end of the pumping pump 17, one end of the branch flow pipe 19 is fixedly installed at the output end of the pumping pump 17, and the other end of the branch flow pipe 19 is fixedly installed on the inner side of the main drainage pipe 20. The main drainage pipe 20 is fixedly installed on one side of the manifold drainage box 6.

[0033] In this embodiment, the basement vacuum drainage flushing anti-clogging component 2 includes a municipal pipeline connecting pipe 21, a first solenoid valve 22, a pump 23, a main outlet pipe 24, a backwash pipe 25, and a second solenoid valve 26. The municipal pipeline connecting pipe 21 is fixedly installed on the rear side of the manifold 6, the first solenoid valve 22 is fixedly installed on the outside of the municipal pipeline connecting pipe 21, the pump 23 is fixedly installed on the front side of the manifold 6, the suction end of the pump 23 is connected to the manifold 6, the main outlet pipe 24 is fixedly installed on the output end of the pump 23, and one end of the backwash pipe 25 is fixedly installed on the main outlet pipe.

A liquid level sensor 27 is installed inside the water collection well 4. When the water flow reaches a certain height, the water pump 17 can be started and the water pumping pipe 18 can be used to extract the water flow. After extraction, the water flow can be transmitted to the confluence drainage box 6 through the branch flow pipe 19 and the main drainage pipe 20. A municipal pipeline connecting pipe 21 connected to the municipal pipeline is installed above the confluence drainage box 6, which can prevent water flow from being wasted and from being discharged randomly.

[0034] In this embodiment, the basement vacuum drainage flushing anti-clogging component 2 also includes a liquid level sensor 27, a control cabinet 28, an alarm module 29, and a signal transmission module 30.

[0036] In this embodiment, an installation groove is provided at the bottom of the water collection well 4, and the sand discharge pipe 11 is installed inside the installation groove. The sand discharge pipe 11 and the water collection pipe 12 form an L-shape. When the water flow is low, the pump 23 can be started to transmit the water flow inside the drainage tank 6 through the main water outlet pipe 24 to multiple backwash pipes 25. The backwash pipes 25 can flush the filter screen 13 inside the sand discharge pipe 11 to prevent mud and sand from clogging it.

[0037] In this embodiment, a sealing top plate is provided on the top of the water collection well 4, and a sealing rubber ring is provided at the connection between the sealing top plate and the water collection well 4; the sealing top plate allows the water collection well 4 to collect water flow when the vacuum branch pipeline 15 is drawing negative pressure, so that the water pump 17 can draw and discharge the water flow.

[0038] Specifically, the operation involves controlling the vacuum pump 5 to start, and through the cooperation of the main vacuum pipeline 14 and the vacuum branch pipeline 15, creating negative pressure inside the water collection well 4. This allows water to flow through the water collection pipe 12 and the sand discharge pipe 11 into the water collection well 4. A filter screen 13 is installed on one side of the water collection pipe 12 and inside the sand discharge pipe 11 to block sediment. A one-way valve 16 is installed on the outside of the vacuum branch pipeline 15 to prevent water from entering the vacuum pump 5. A level sensor 27 is installed inside the water collection well 4. When the water level is detected to reach a certain height, the pump 17 is started, and the pumping pipe 18 draws the water. After drawing, the water is transmitted to the manifold drainage box 6 through the branch flow pipe 19 and the main drainage pipeline 20. A [unclear - possibly a device or device] is installed above the manifold drainage box 6. The municipal pipeline 21, which is connected to the municipal pipeline, ensures that water flow is not wasted and is not discharged arbitrarily. When the water level is consistently at the height of the level sensor 27, the alarm module 29 can transmit an alarm signal through the signal transmission module 30, allowing personnel to take action to prevent damage to the base plate due to excessive buoyancy when the water flow is high. When the water flow is low, the pump 23 can be started to transmit the water flow inside the manifold drainage tank 6 through the main outlet pipeline 24 to multiple backwashing pipelines 25. The backwashing pipelines 25 can flush the filter screen 13 inside the sand discharge pipeline 11 to prevent silt blockage. After the water flow is discharged, the second solenoid valve 26 above the sand discharge pipeline 11 can be opened to allow silt to be discharged from the sand discharge pipeline 11.
