The application discloses an intelligent detection device and method for detecting the impermeability of high-performance concrete, and relates to the technical field of high-performance concrete impermeability detection. The device and method are characterized by the cooperation between a hydraulic rod, an impermeability detection mechanism, a driving mechanism, a containing seat mechanism and a water supply mechanism. The driving mechanism can drive the impermeability detection mechanism to intermittently contact the top surface of multiple high-performance concrete test blocks at different positions. The impermeability detection mechanism is used to detect the humidity of multiple points on the top surface of the high-performance concrete test blocks. The impermeability of the high-performance concrete test blocks is evaluated through comprehensive detection of multiple points, which can avoid accidental errors caused by single-point detection, dynamically capture the humidity change characteristics of different areas on the top surface of the test blocks during the penetration process, improve the comprehensiveness of the impermeability evaluation, and make the impermeability detection results more accurate and reliable.

This invention provides a controllable-depth penetration device and method. The device includes: a deep-burying module, an explosive installation module, a gas compression module, a depth detection module, and a management module. After the management module obtains the final explosion depth scale, it controls the deep-burying module to limit its movement at the final explosion depth scale, disconnects the explosive installation module from the deep-burying module, and controls the gas compression module to drive the explosive installation module to move to the final explosion depth scale inside the deep-burying module. The explosive installation module then detonates at the final explosion depth scale. This method of penetrating first and then controlling the explosive depth provides adjustable explosion depth, increasing the feasibility of achieving the optimal explosion effect. Furthermore, the management module records acceleration data during the penetration process, providing practical data reference for obtaining the optimal depth and improving the reliability of the explosion effect.

The present invention relates to a technique for forming a via hole having a diameter of approximately 0.1 mm or slightly larger in a thin glass, made of a glass material, such as a thin semiconductor substrate or an interposer, wherein a bar-shaped heating element having an outer diameter that corresponds exactly to the diameter of a via-hole in a thin glass to be processed is heated to a high temperature and then rotated in place to form the via-hole that penetrates from one surface to the other surface of the thin glass. According to the present invention, the outer diameter is formed small in the direction opposite the penetration direction of a high-frequency heating element, thereby preventing the occurrence of cracks during the penetration process.

The application relates to the technical field of geotechnical engineering, and discloses a method for determining the limit value of puncture and extrusion damage in the pile shoe penetration process, which obtains the measured resistance data of the pile shoe in the layered soil to construct a measured penetration resistance curve, and constructs corresponding theoretical penetration resistance curves of pure sand and pure clay by using a bearing capacity formula. The limit value is determined based on the characteristics of the measured curve and comparison results: for the sand-on-clay working condition, the vertical distance from the growth inflection point of the measured curve to the interface of the lower stratum is determined as the puncture damage limit value; for the clay-on-sand working condition, the vertical distance from the position where the resistance ratio of the measured curve to the pure clay theoretical curve reaches the extrusion effect control threshold to the interface of the lower stratum is determined as the extrusion damage limit value. Finally, the above limit value is output, and the area where the distance from the bottom surface of the pile shoe to the interface between layers is less than the limit value is defined as a critical risk area. The application realizes quantitative definition of the position where the damage mode of the layered soil occurs.
