Then, the clamping and positioning is released, and the building concrete sample falls into the positioning ring 256 in the corresponding material placement piece 25 and contacts the third sealing rubber ring 255, so as to automatically load the building concrete sample;

[0045] In this way, the building concrete samples on both sides are transported to the corresponding positioning rings 256 on the material placement parts 25 through the transport mechanisms 5 and the loading mechanisms 6 on both sides and contacted with the third sealing rubber ring 255;

The movably clamped part is connected to the top of the bottom sealing cylinder 36, the bottom end of the material storage cylinder 35 contacts the upper surface of the second sealing rubber ring 254, and the top end of the bottom sealing cylinder 36 contacts the lower surface of the first sealing rubber ring 253, so as to seal and clamp the material storage cylinder 35, the bottom sealing cylinder 36 and one of the material placing parts 25, and the fourth sealing rubber ring 373 at the bottom end of the ring frame 371 contacts the upper surface of the building concrete sample and squeezes the tension spring 374, so as to effectively limit the upper surface of the building concrete sample, thereby realizing effective sealing of the lower surface of the building concrete sample;

[0048] Subsequently, the gas output system and the flow control valve 363 are controlled to be turned on, and the booster pump 362 is turned on to adjust the gas pressure. The gas is introduced into the bottom sealing cylinder 36 through the second connecting pipe 364 and the second pipe 361, and then introduced into the building concrete sample through the connecting clamp ring 252.
