Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a concrete core drilling and sampling device. Background Technology

[0002] High chloride ion content impairs concrete's resistance to chemical corrosion, directly affecting its wear resistance and thus reducing its strength. This can easily lead to loosening and insufficient load-bearing capacity in concrete structures, shortening their service life and causing premature failure. The presence of chloride ions accelerates the chemical erosion process of concrete, damaging its internal structure and reducing its durability. This may result in concrete being more prone to cracking and spalling during long-term use. Furthermore, chloride ions are a major cause of steel reinforcement corrosion. When chloride ions penetrate the concrete and come into contact with the steel reinforcement, they damage the passivation film on the surface of the reinforcement, leading to electrochemical corrosion. This corrosion process reduces the strength and load-bearing capacity of the steel reinforcement, thus affecting the stability of the entire concrete structure. The rust products produced by steel reinforcement corrosion expand and fill the voids between the reinforcement and concrete, reducing the bond strength between them. This affects the overall performance of the concrete structure and may even lead to structural failure.

[0003] Existing concrete pile testing equipment can only perform simple sampling and testing of concrete piles. However, in marine engineering construction, the chloride ion content generated inside concrete piles varies at different depths of seawater, and the conditions for chloride ion generation in concrete exhibit certain regularities. Conventional sampling equipment cannot perform real-time sampling and testing of concrete piles. Therefore, there is an urgent need for a core drilling and sampling device that can detect the regular chloride ion generation in concrete piles at different depths of seawater to solve the above problems.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example

[0021] like Figures 1 to 3 As shown, this utility model provides a concrete core drilling sampling device, including a reinforced concrete pile, a drilling machine fixedly installed on the top of the reinforced concrete pile, a drilling assembly fixedly connected to the bottom of the drilling machine, and a detection component provided inside the drilling assembly.

[0022] As a further explanation of this embodiment, existing concrete pile testing equipment can only perform simple sampling and testing of concrete piles. However, in marine engineering construction, the chloride ion content generated inside concrete piles varies at different depths of seawater, and the conditions for chloride ion generation in concrete have a certain regularity. Conventional sampling equipment in the prior art cannot perform real-time sampling and testing of concrete piles. Therefore, there is an urgent need for a core drilling sampling device for detecting the regular chloride ion generation in concrete piles at different depths of seawater. In this embodiment, the drilling assembly 2 is first driven by a drilling machine to perform core drilling on any concrete pile 1, so that the detection assembly 3 goes deeper into the concrete pile 1 along with the drilling assembly 2. When the drilling assembly 2 reaches the predetermined depth, the drilling stops and the detection assembly 3 is activated to continuously detect and sample the inner wall of the concrete pile 1. The sampled data is uploaded to the data processing center for classification and management, forming a supervised machine learning dataset. Based on Fick's second law, the supervised dataset is used to obtain the time-varying parameters of chloride ion transport in the concrete structure using the supervised dataset big data machine learning module. Finally, an intelligent detection center for durability safety platform is formed to detect the durability of concrete piles 1 located in the same area or the same building, thereby performing the most basic and accurate detection of structures used in marine engineering construction.

[0023] Based on a preferred embodiment of a concrete core drilling sampling device, the drilling assembly 2 includes a hollow drill rod 21 fixedly connected to the drilling machine, and a drill bit 22 is fixedly connected to the bottom of the hollow drill rod 21.

[0024] Based on a preferred embodiment of a concrete core drilling sampling device, the detection component 3 includes multiple bearings 31 fixedly installed inside the hollow drill rod 21, and the multiple bearings 31 are connected to the same mounting rod 32. A base 33 is fixedly installed inside the mounting rod 32, and multiple detection sensors 34 are sleeved on the base 33.

[0025] As a further explanation of this embodiment, the concrete pile 1 in this embodiment is generally divided into the following zones according to the depth of immersion in seawater: atmospheric zone, splash zone, tidal zone, fully immersed zone, and sea mud zone. The bottom of the hollow drill rod 21 can reach a depth that is mostly in the fully immersed zone. Taking the chloride ion sensor results in the fully immersed zone as a reference, a concrete humidity probe is added in both the tidal zone and the splash zone to continuously measure the concrete humidity history in the tidal zone and the splash zone, and analyze the average humidity of the concrete in the tidal zone and the splash zone. Based on the potential data of chloride ion detection sensors 34 in the tidal zone and splash zone measured on-site, and the concrete humidity results, the chloride ion concentration analysis is performed by establishing a quantitative relationship between the chloride ion probe potential and the concrete humidity through indoor experiments using a combination of chloride ion detection sensors 34 and humidity probes. This quantitative relationship is then used to correct and calibrate the chloride ion concentration results in the tidal zone and splash zone. Furthermore, the above data analysis results can be applied to the analysis of chloride ion content data obtained from actual detection in multiple areas. Specifically, the seawater immersion depth of the reinforced concrete pile 1 is measured, and corresponding atmospheric, splash, tidal, fully immersed, and marine mud zones are delineated. Multiple detection sensors 34 are then pre-installed on the base 33 according to the zone divisions. Each detection sensor 34 performs classified sampling and detection for each zone, and the data is uploaded to the data center for further classification and management and learning. This achieves the installation of a gradient array of detection sensors 34, thereby obtaining a more accurate understanding of chloride ion generation patterns within the concrete pile 1.

[0026] Based on a preferred embodiment of a concrete core drilling sampling device, the side wall of the mounting rod 32 is provided with a plurality of avoidance holes 321 for avoiding the detection sensor 34, and the hollow drill rod 21 is provided with a plurality of receiving holes 211 corresponding one-to-one with the avoidance holes 321.

[0027] As a further explanation of this embodiment, the chloride ion detection sensor 34 in this embodiment is an optical fiber sensor. Currently, optical fiber sensors used to detect chloride ion concentration are mainly divided into optical fiber sensors based on the refractive index of the environment and optical fiber sensors based on the principle of fluorescence quenching. When the refractive index of the external medium changes, the center wavelength of the long-period fiber grating will shift. When the chloride ion concentration changes, it will cause the refractive index in the solution to change. Therefore, by observing and recording the change in the center wavelength of the long-period grating, the concentration of chloride ions can be detected. In order to further enhance the accuracy of the optical fiber sensor detection, corresponding holes are opened on the side wall of the mounting rod 32 and the side wall of the hollow drill rod 21 to avoid the emission source of the optical fiber sensor, thereby improving the accuracy of the sampling detection results.

[0028] Based on a preferred embodiment provided by a concrete core drilling sampling device, a mud-proof mesh is fixedly installed in each of the receiving holes 211.

[0029] Based on a preferred embodiment of a concrete core drilling sampling device, the diameter of the drill bit 22 is larger than the diameter of the hollow drill rod 21.
