Abstract
Description
Technical Field
[0001] This utility model relates to the field of mud sampling technology, specifically a mud sampling device for construction. Background Technology
[0002] In construction, drilling mud plays a vital role in wall protection, slag removal, and cooling, especially in the construction of bored piles and diaphragm walls. Therefore, the testing of drilling mud is of paramount importance.
[0003] Currently, mud sampling is mainly done at the borehole opening. During construction, as the depth increases, the mud circulation path becomes longer, and the soil, sand, and other materials in the mud will inevitably sink under their own weight, resulting in a significant difference in the properties of the mud at the bottom of the borehole and the mud at the borehole opening. Alternatively, an open-type sampler can be placed at the bottom of the pile, and an open-type sampler can be used for sampling, which can easily cause the sampled mud to be disturbed by external factors.
[0004] Sampling at the borehole opening can lead to problems because the properties of the mud at the bottom of the borehole differ significantly from those at the opening, resulting in samples that do not accurately reflect the actual conditions and can affect the quality of the project. Sampling with an open sampler can also cause the sampled mud to be affected by external interference, as the physical properties of the mud circulating to the borehole opening change significantly, leading to contamination of the sampled mud and preventing it from accurately reflecting the actual conditions at the bottom of the borehole, thus affecting the quality of the project. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a construction mud sampling device, which solves the problem that the sampled mud cannot reflect the true situation, thus affecting the quality of the project.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction mud sampling device, comprising a mud sampling chamber, a gate, and a piston port. The gate is engaged with the mud sampling chamber, and the piston port is located at the bottom of the mud sampling chamber. The gate is used to open and close the mud sampling chamber, and the piston port is used to discharge the sampled mud. The mud sampling chamber comprises a square device plate and a top cover plate. The top cover plate is fixed inside the square device plate, and a lifting ring is fixedly installed on the top of the square device plate.
[0007] The gate includes a lifting steel plate and a sealing strip. The sealing strip is fixedly installed on both the inner and outer sides of the lifting steel plate. A lifting ring is fixedly installed on the top of the lifting steel plate, and a pull rope is connected to the lifting ring. Sliding inserts are installed at both ends of the lifting steel plate.
[0008] Preferably, the square device plate is connected to a gate, and the gate is provided with a sliding groove.
