Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:
as shown in FIG. 1, the present embodiment provides a multifunctional miniature static sounding rod, which is composed of a probe 1, a connecting rod 2 and a connecting top plate 3.
The probe 1 is provided in three forms in total according to different penetration depths, different soil conditions and different structure conditions. The top surfaces of the probes 1 in the three forms are all provided with grooves, are tapped in the grooves and are used for placing and connecting the miniature pull pressure sensor.
As shown in fig. 2, the first probe 1 is a conventional tapered probe having a cone angle of 60 °. The conical probe is mainly used for indoor model tests in sandy soil and silt, and the corresponding penetration resistance corresponding to the soil property parameters is provided according to various corresponding specifications.
As shown in fig. 3, the second probe 1 is a cylindrical probe (commonly known as T-bar) comprising a horizontally placed cylinder having a diameter corresponding to the diameter of the connecting rod 2 and a length of 60 mm. The diameter of the cylindrical probe can be selected within the range of 10-40 mm, and the length can be selected within the range of 40-400 mm. The cylindrical probe is suitable for indoor model tests in cohesive soil, and the corresponding theoretical solution of the penetration resistance in the penetration process is also applied by various specifications.
The third probe 3 is a drag reduction ring probe, which comprises a drag reduction ring and a connecting part above the drag reduction ring, wherein the connecting part is generally a cylinder with a threaded blind hole at the upper part, the drag reduction ring is in a circular table shape with the diameter of the bottom surface smaller than that of the top surface, the diameter of the top surface of the drag reduction ring is generally selected within the range of 110-180% of the diameter of the connecting rod 2, and the included angle between the side surface of the drag reduction ring and the vertical direction is generally selected within the range of 10-45 degrees. The drag reduction ring probe is a probe type with a brand-new design, the drag reduction ring can change a soil body damage mode in a sinking process, friction resistance is greatly reduced, total resistance of penetration of a probe rod is further reduced, the diameter and the inclination angle of the top surface of the drag reduction ring are changed, and end resistance and friction resistance change rules can be obtained through the measurement data of an upper miniature pull pressure sensor and a lower miniature pull pressure sensor. Therefore, the probe can reflect the stress condition of the anti-drag structure in the installation process more truly.
The connecting rod 2 is a hollow thin-wall steel pipe with two through ends, the diameter of the connecting rod 2 is determined according to the size of the existing miniature pull pressure sensor with the minimum size and the penetration resistance value listed by the corresponding specification, for example, the inner diameter can be selected to be 10mm, the outer diameter can be selected to be 12mm, and the length can be selected to be 60 cm. Generally, the length of the connecting rod 2 is 50-200 cm. The both ends of connecting rod 2 are processed a degree of depth respectively and are 1 mm's recess, simultaneously in the recess internal tapping of connecting rod 2 for place and connect miniature pressure sensor that draws.
As shown in fig. 4, the connecting top plate 3 includes a square plate structure and a connecting portion disposed at a lower portion of the plate structure, and a groove is formed in a bottom surface of the connecting portion and is tapped in the groove for placing and connecting the micro pull pressure sensor. The square flat plate structure of the connecting top plate 3 is provided with four screw holes at four corners respectively, so that the loading device corresponding to the upper part can be conveniently connected, accurate levelness adjustment can be carried out, and the vertical degree of the probe rod is ensured to ensure the test precision.
The connecting rod 2 is connected with the probe 1 through an internal miniature pull pressure sensor and is not in direct contact with the probe, so that the resistance of the conical head is only end resistance. The connecting rod 2 and the connecting top plate 3 are also connected through an internal miniature pull pressure sensor, and the connecting rod 2 is not in direct contact with the connecting top plate 3, so that the miniature pull pressure sensor can measure the total resistance of the probe 1 and the connecting rod 2. The connecting rod 2 is punched at a position close to the connecting top plate 3 to lead out two miniature connecting wires for pulling the pressure sensors from the connecting rod 2, so that the effective length of a measuring range is ensured, and the interference of a wire to a soil body is prevented. The pile end resistance and the total resistance are measured without interruption in the penetration process, so that the frictional resistance of the connecting rod 2 is calculated reversely, the sensor at the bottom can measure the end resistance in time, the sensor at the top can measure the total resistance, and the frictional resistance is calculated by the difference value of the two.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various changes without departing from the spirit and the scope of the invention as claimed.
