Problems solved by technology

[0003] However, according to the research on the field operation test of static penetration sounding in Shanghai for many years, a series of problems such as temperature drift and operating inclination of traditional static penetration sounding instrument can no longer meet the requirements of high-precision measurement
At the same time, due to the insufficient design of traditional instruments, it is difficult to identify the authenticity of the collected data

Embodiment

[0029] Embodiment: the design and principle of the inclinometer device of the present embodiment are as follows: the inclinometer device in the present embodiment is made up of gravity accelerometer and processing chip, promptly adds X, Y, Z on single bridge probe 1 or double bridge probe 10 The gravitational accelerometers in three directions measure the verticality, and the measured verticality is transmitted to the processing chip 5, and then transmitted to the data acquisition instrument after processing.

[0030] Such as Figure 5 , 6 According to the readings of the three gravity accelerometers, the angle between the direction of gravity and the axis of the instrument is obtained through calculation, that is, the inclination angle. The angle α between the Z axis and the direction of gravity g is the inclination angle of the measured point.

[0031] The measured values ​​of the X, Y, and Z axes are respectively: the measured values ​​of the X, Y, and Z axes are: Gx, Gy,...

Abstract

The invention relates to the field of ground survey, in particular to a probing method of a static penetrometer. The probing method is characterized by at least including the following steps: installing a survey device on a static probing probe, and enabling the survey device to measure an inclined angle of the static probing probe; and arranging an analog-to-digital converter on the static probing probe, and enabling the analog-to-digital converter to receive analog signals measured by a static probing sensor, convert the analog signals into digital signals and transmit the digital signals to a data collector. The probing method has the advantages of being digitalized, capable of measuring angle values and temperature values, unidirectional in data, capable of performing controlling through a touch screen, audio-visual in data and capable of performing wireless transmission.

Description

technical field [0001] The invention relates to the field of land survey, in particular to a detection method of a static penetration sounder. Background technique [0002] Static CPT refers to using the pressure device to press the penetrating rod with the probe into the test soil layer, and through the measurement system to measure the penetration resistance of the soil, some basic physical and mechanical properties of the soil can be determined, such as the deformation mode of the soil. volume, the allowable bearing capacity of the soil, etc. Compared with conventional exploration methods such as "drilling-sampling-indoor test", it has the characteristics of fast, accurate, economical and labor-saving. The static penetration test is an important in-situ test method in engineering geological exploration. [0003] However, according to the research on field operation tests of static penetration sounding in the Shanghai area for many years, a series of problems such as tem...
