specific Embodiment approach 1
[0009] Embodiment 1: As shown in Figure 1, the detection device for detecting the permeability of the concrete surface described in this embodiment includes a pre-embedded pipe 2, a semi-embedded pipe 3, a short pipe 4, a nut 5, a first humidity Sensor 6, the second humidity sensor 7, the first partition 4-1 with through holes and the second partition 4-2 with through holes; the side wall of the embedded pipe 2 is evenly opened with several through holes 2-1, there is a hole 5-1 on the top of the nut 5, the middle side wall of the embedded pipe 2 and one end of the half-embedded pipe 3 are vertically fixed together to form a T-shape, the embedded pipe 2 and the half-embedded pipe The buried pipe 3 is connected, and the side wall of the other end of the semi-embedded pipe 3 is provided with an external thread 3-1 and is threadedly connected with one end of the short pipe 4. The other end of the short pipe 4 is screwed into the nut 5, and the short pipe 4 A first partition 4-1 w...
specific Embodiment approach 2
[0010] Embodiment 2: The pre-embedded pipe 2 and semi-embedded pipe 3 in this embodiment are all stainless steel pipes. Stainless steel pipes are not easily oxidized. Other components and connections are the same as those in the first embodiment.
specific Embodiment approach 3
[0011] Specific embodiment three: As shown in Figure 1, the detection device described in this embodiment also includes a pre-embedded column core 2-2 and a half-embedded column core 3-2, and a pre-embedded column core 2-2 and a half-embedded column core 3-2 are vertically connected, the pre-embedded column core 2-2 is arranged in the pre-embedded pipe 2, and the half-embedded column core 3-2 is arranged in the half-embedded pipe 3. The purpose of setting the embedded column core 2-2 and the semi-embedded column core 3-2 is to reduce the space volume of the embedded tube 2 and the semi-embedded tube 3, thereby reducing the gas space and improving the accuracy of humidity measurement . Other compositions and connections are the same as those in the first or second embodiment.
