According to the probe structure for measuring the concrete irrigation height below the slurry surface, when the concrete surface position below the slurry surface needs to be measured, the concrete irrigation height below the slurry surface is measured by arranging the measuring tools such as the measuring rope 30 on the probe structure; the cone-shaped probe body 10 sinks rapidly in the slurry, penetrates through a loose sediment layer and is embedded into a concrete surface with large resistance at the lower part of the sediment layer, the slurry and the sediment layer cannot enter the collecting tank 20 under the action of the transition ring surface 12 in the sinking process of the probe body 10, when the probe body 10 is extracted, the concrete can preferentially enter the collecting tank 20, and in the extracting process of the probe body 10, the concrete which has entered the collecting tank 20 can block the slurry and the sediment layer, so that the slurry and the sediment layer cannot easily enter the collecting tank 20; after the probe body 10 is extracted, observing the collecting tank 20, and if concrete exists, indicating that the concrete surface is reached; thus, the irrigation height of the concrete can be directly and accurately measured, and the error of measuring the irrigation height of the concrete is reduced.
In this embodiment, the probe body 10 includes an upper probe portion 11 and a lower probe portion 13, the upper probe portion 11 is located above the transition ring surface 12 and contacts the transition ring surface 12, and the lower probe portion 13 is located below the transition ring surface 12 and contacts the transition ring surface 12; the collecting groove 20 is arranged on the lower probe part 13; like this, along top-down direction, go up to visit portion 11, transition anchor ring 12 and visit portion 13 down and arrange according to the preface, under the cooperation of visiting portion 11, transition anchor ring 12 and visiting portion 13 down, visit the body 10 when sinking, effectively prevent mud and sediment layer entering collecting vat 20 to guarantee the measuring accuracy.
In addition, the upper probe part 11, the transition ring surface 12 and the lower probe part 13 are integrally formed; the production of the probe body 10 is convenient, and meanwhile, connecting elements among the upper probe part 11, the transition ring surface 12 and the lower probe part 13 are avoided, so that the manufacturing cost of the probe body 10 is reduced; in addition, the connection stability of the upper probe part 11, the transition ring surface 12 and the lower probe part 13 is greatly enhanced, so that the service life of the probe body 10 is prolonged.
The downward probing part 13 is in a conical shape, and the upward probing part 13 is in a big-end-up shape along the direction from top to bottom; the resistance of the slurry and the sediment layer to the probe body 10 is reduced, and the probe body 10 is convenient to sink.
Specifically, the collecting tank 20 includes a tank bottom extending into the probe body 10 and tank walls formed between the tank bottom and an opening of the collecting tank 20, and the tank walls are arranged in an inclined manner along a top-down direction; in this way, the phenomenon that slurry or sediment enters the collecting tank 20 in the sinking process of the probe body 10 can be avoided to the greatest extent, and the accuracy of measuring the concrete irrigation height below the slurry surface is improved; also, with this arrangement, the collection groove 20 does not enhance resistance to sinking of the probe 10, thereby facilitating sinking of the probe 10.
Furthermore, along the direction deviating from the opening of the collecting tank 20, the bottom of the tank protrudes inwards and is in an arc surface shape; when the probe body 10 is extracted, concrete enters the collecting tank 20, and under the action of the arc-surface-shaped tank bottom, the buffer effect is exerted on substances entering the collecting tank 20, so that the shaking of the probe body 10 is reduced, and the accuracy of measuring the concrete irrigation height below the mud surface is enhanced.
