Description

Technical Field

[0002] Permeable concrete, also known as porous concrete, sandless concrete, and permeable floor, is a porous lightweight concrete made of aggregate, cement, reinforcing agent and water. It does not contain fine aggregate. Permeable concrete is composed of a thin layer of cement slurry covered on the surface of coarse aggregate and bonded together to form a honeycomb structure with evenly distributed pores. Therefore, it has the characteristics of air permeability, water permeability and light weight. At the same time, it is an excellent paving material for protecting groundwater, maintaining ecological balance, and alleviating urban heat island effect. It is beneficial to the benign development of the human living environment and urban rainwater management and water pollution prevention and control. It is of special importance. After the production of permeable concrete is completed, it is usually necessary to test the water-based concrete.

[0003] Current testing devices usually focus on measuring water permeability, but in actual projects, the performance evaluation of concrete may involve more parameters and indicators, such as considering the impact of temperature on concrete performance. Changes in temperature will significantly affect concrete's durability, shrinkage performance, crack resistance and other indicators. The current testing devices are relatively single in function and cannot be tested at one time.

[0004] Therefore, it is necessary to provide a new permeable concrete testing device to solve the above technical problems. Utility Model Content

[0023] It should be noted that: the scale 7 is used to facilitate observation of the water level, the buoy 8 is used to facilitate recording of the water level, and the setting of the heating device 9 and the heating copper tube 10 makes it convenient to drive the heating device 9 to heat the tested water body through the controller 11, thereby obtaining the changes of the water-based concrete under high temperature.

[0025] It should be noted that when the user needs to recycle the test water, the user opens the valve on the suction pipe 14 and then drives the pump head 12 to draw the water into the inner cavity of the drainage pipe 13 through the suction pipe 14, and then discharges the water into the inner cavity of the test shell 1 again, thereby recycling the water and reducing resource waste.

[0026] refer to Figure 1 and Figure 3 As shown, the bidirectional screw rod 501 is arranged at the bottom of the inner cavity of the test shell 1, one side of the bidirectional screw rod 501 passes through the outside of the test shell 1 and is fixedly connected to the turntable 502, threaded sleeves 52 are sleeved on both sides of the surface of the bidirectional screw rod 501, the front and rear sides of the two threaded sleeves 52 are fixedly connected to extension plates 503, a clamping plate 504 is fixedly connected between the tops of the two extension plates 503, one side of the extension plate 503 is fixedly connected to a sliding sleeve 505, the inner cavity of the sliding sleeve 505 is provided with a sliding rod 506, both sides of the sliding rod 506 are fixedly connected to the inner wall of the test shell 1, one side of the clamping plate 504 is fixedly connected to a reinforcing plate 507, and the bottom of the reinforcing plate 507 is fixedly connected to the extension plate 503.
