Description

Technical Field

[0001] The utility model belongs to the technical field of water permeability coefficient, and specifically relates to a water permeability coefficient detection tool. Background Art

[0002] Permeable concrete refers to porous concrete made of cement, coarse aggregate, water and appropriate admixtures. It is also called sandless concrete, sandless concrete, and permeable floor. It is a porous lightweight concrete made of aggregate, cement, reinforcing agent and water, and it does not contain fine aggregate. Permeable concrete is composed of a thin layer of cement slurry covered on the surface of coarse aggregate, which are bonded together to form a honeycomb structure with evenly distributed pores. Therefore, it has the characteristics of air permeability, water permeability and light weight. Therefore, in recent years, permeable concrete has been widely used in urban roads such as parking lots, sidewalks, and park trails.

[0003] After searching, a document with publication number (CN216411009U) discloses a device for detecting the permeability coefficient of permeable concrete, including a box body, a detection box is fixedly installed on the left side of the box body, a clamping mechanism is fixedly installed inside the detection box, a partition rod is fixedly installed inside the detection box and at the bottom of the clamping mechanism, and the clamping mechanism includes a motor, a rotating shaft, a connecting plate, a clamping base, a clamping plate and a telescopic rod.

[0004] The above device drives the clamping plate to move through the telescopic clamping base of the telescopic rod to make it more stable, thereby achieving the effect of convenient fixing. By setting a water pump, water is first injected into the water tank from the water inlet pipe, and the water inside the water tank is introduced into the water pipe through the water pump. The water inside the water pipe then flows into the nozzle, and the nozzle sprays water on the permeable concrete for detection. However, the above device lacks peripheral seals and water injection seals, which causes the spray water to fall from all sides of the permeable concrete and mix with the infiltrated water, thereby reducing the accuracy of the permeability performance detection.

[0005] In view of this, the present utility model is proposed. Utility Model Content
