Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a concrete sampling device. Background Art

[0002] Concrete, also known as "concrete," is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. Concrete, commonly referred to as cement as the binder, sand and stone as aggregates, and water (which may contain admixtures and additives) mixed in a specific proportion, is widely used in civil engineering. Cement concrete, also known as ordinary concrete, is widely used in civil engineering.

[0003] When mixing concrete, sampling needs to be done from the center to facilitate observation of the internal mixing conditions. Traditional sampling devices are unable to remove the residual concrete inside in time after sampling, which causes the concrete to solidify, making the sampling device unable to be used multiple times. Moreover, after sampling, the sample needs to be poured out and cannot be easily removed. Therefore, a concrete sampling device is proposed. Utility Model Content
