The application provides a method for detecting the depth of a conduit in concrete, which comprises the following steps: obtaining the medium density of the space between a first pressure sensor and a second pressure sensor on the conduit, and determining the first space position type of the space between the first pressure sensor and the second pressure sensor on the conduit; obtaining the first medium type corresponding to the position of a first vibration sensor and the second medium type corresponding to the position of a second vibration sensor, and determining the second space position type of the space between the first vibration sensor and the second vibration sensor on the conduit; if the first space position type and the second space position type are consistent, determining the first depth information based on the medium density, determining the second depth information based on the vibration signal, and determining the target depth information according to the first depth information and the second depth information. Through the method, the detection reliability can be improved by avoiding the single signal misjudgment, and the depth detection precision is improved by comprehensively calculating the target depth.

This utility model discloses a grounding strip with a braided structure, belonging to the field of lightning protection grounding technology, including a graphite braided strip and a reinforcing braided layer. The graphite braided strip is formed by weaving graphite wires. The reinforcing braided layer is a layered structure formed by weaving a mixture of reinforcing wires and graphite wires, and the layered structure of the reinforcing braided layer is arranged circumferentially along the interior of the graphite braided strip. The graphite braided strip, woven from graphite wires, provides excellent conductivity and corrosion resistance. The reinforcing braided layer, formed by weaving a mixture of reinforcing wires and graphite wires, enhances the mechanical strength of the grounding strip and reduces the probability of damage or breakage. The mixed weaving of graphite wires and reinforcing wires serves as a structural transition, avoiding discontinuities or abrupt changes in the resistivity of the graphite braided strip, which would lead to an increase in overall grounding resistance and a reduction in current discharge efficiency. The integrated braided structure gives the grounding strip both flexibility and strength, facilitating installation and transportation.
