[0002] Cities can be like sponges, with good "elasticity" in adapting to environmental changes and responding to natural disasters. The internationally accepted term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water can be released and utilized, allowing rainwater to migrate freely in the city.

[0003] When the soil layer is saturated with water, the phenomenon that the water in the soil moves downward under the influence of gravity is called permeability. Soil permeability is one of the important properties of soil. It can measure the ability of soil to retain water and is also an important indicator of sponge cities. The permeability coefficient of soil is the amount of water that free water in saturated soil can pass through a unit area of ​​soil in a unit time under a unit water pressure gradient.

[0004] The existing soil permeability coefficient test device includes a double-layer iron ring base, a bracket, two water supply bottles with rubber stoppers inverted on the bracket and a pair of water supply oblique glass tubes. The base consists of an inner ring and an outer ring. The water supply bottle is located above the base. The upper ends of the water supply oblique glass tubes are inserted into the two water supply bottles from the bottoms thereof and are located in the water body.

The base 1 is composed of an inner ring 6 and an outer ring 7 sleeved on the inner ring 6 to form a double-ring base, and a gravel layer 8 is laid on the bottom soil of the inner ring 6 and the bottom soil between the inner ring 6 and the outer ring 7. The water supply bottle 2 is located directly above the base, and the upper ends of the pair of water supply oblique-mouth glass tubes 3 are respectively inserted into the two water supply bottles 2 from the bottom thereof and are located in the water body, the lower end of one water supply oblique-mouth glass tube 3 is inserted below the water surface of the inner ring 6, and the lower end of the other water supply oblique-mouth glass tube 3 is inserted below the water surface between the inner ring 6 and the outer ring 7. The remote liquid level meter 5 is communicatively connected to the terminal controller. The remote liquid level meter 5 is arranged in the water supply bottle 2. The remote liquid level meter 5 uploads the collected liquid level data to the terminal controller for display. The terminal controller synchronously calculates and records the soil infiltration amount according to the liquid level data.

[0023] The upper ends of the pair of pressure difference controlling beveled glass tubes 4 are respectively inserted into the two water supply bottles 2 from the bottom thereof and are located above the water surface, the lower end of one of the pressure difference controlling beveled glass tubes 4 is inserted into the inner ring 6 and the upper edge of the bevel is flush with the water surface, while the lower end of the other pressure difference controlling beveled glass tube 4 is inserted between the inner ring 6 and the outer ring 7 and the upper edge of the bevel is flush with the water surface, and the lower ends of the pair of pressure difference controlling beveled glass tubes 5 are beveled at the same height.

[0024] The water supply oblique-mouth glass tube 3 is composed of a glass tube and a rubber hose connected to the lower end thereof, and a valve 9 is provided on the rubber hose.

[0025] The bracket 1 includes four support columns 10 and two support plates 11 horizontally mounted on the support columns 10. The four support columns 10 are located at the periphery of the base, and the top and bottom surfaces of the water supply bottle 2 are fixed on the upper support plate and the lower support plate respectively.

[0026] The utility model adds the automatic water supply function of the water supply bottle, the real-time liquid level monitoring function and the remote information transmission function to the original soil permeability coefficient test device, and can remotely transmit the soil water seepage data, and the terminal controller can monitor it in real time. The controller has a timer, which can synchronously calculate and record the soil permeability.

[0027] Calculate the soil permeability coefficient as follows:

[0028]

[0029] In the formula: kT is the permeability coefficient; Q is the amount of water that has seeped in. The double-ring method is the amount of water that has seeped in from the inner ring; t is the time; Ah is the area of ​​the iron ring. The double-ring method is the area of ​​the inner ring.

[0030] The soil permeability coefficient test value shall comply with the provisions of the design documents. If there is no clear provision in the design documents, it shall comply with the limit value of 1×10 in the "Guangdong Province Green Building Testing Standard" DBJ / T-234-2021. -6 ~1×10 -3 m / s.

[0031] When the utility model is installed and used, the double-layer iron rings (inner ring and outer ring) of the base are placed in a concentric circle manner and the lower ends thereof are inserted into the soil, and then a 2 cm thick gravel layer is evenly spread on the soil at the bottom of the double-layer iron rings, and then clean water is injected into the double rings until they are full, and the bracket is placed in a horizontal position. Two water supply bottles filled with clean water are inverted on the bracket, and two water supply oblique-mouth glass tubes are respectively inserted below the water surface between the inner ring and the inner and outer rings, and then the test begins. During the test, it is necessary to ensure that the water level in the double rings remains unchanged. The utility model adds a pressure difference control oblique-mouth glass tube under each water supply bottle, and the oblique mouth is at the same height as the water surface of the double rings. The tube is the only air intake pipe of the water supply bottle. When the water surface in the double rings is higher than the tube, due to the effect of air pressure, the water in the water supply bottle cannot flow into the ring, and the water injection is stopped. As the soil infiltrates, the water level in the double rings drops. When it is lower than the lower end of the pressure difference controlled oblique glass tube, external gas can enter the water supply bottle, and the water in the water supply bottle can flow into the rings, that is, water injection begins. Therefore, this device can make the water supply bottle automatically supply water to the double rings.

[0032] This device has been put into practical testing and has been used in more than ten projects so far, generating more than 100,000 yuan in economic benefits. It has greatly simplified the procedure for soil permeability testing and is convenient and easy to operate.

[0033] The implementation methods of the utility model are not limited to this. According to the above content of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the utility model, the utility model can also make other various forms of modifications, replacements or changes, all of which fall within the scope of protection of the utility model.
