Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a multi-module-based static penetration process parameter monitoring system and an application method thereof. Background Art

[0002] Geotechnical engineering investigation usually uses some investigation methods and means to obtain the geotechnical conditions and geological environment characteristics of the construction site, which often determines the safety and quality of the building, and therefore becomes an indispensable part of engineering construction. Among them, the commonly used investigation methods and means are engineering geological mapping, drilling, in-situ testing and indoor testing. Static penetration testing is a common means of geotechnical engineering investigation at present. It is an in-situ testing method that divides soil layers, determines soil liquefaction and some basic physical and mechanical properties by measuring penetration resistance, lateral resistance and pore water pressure during the test.

[0003] Among them, the factors that affect the reliability of static penetration data are mainly divided into the following aspects: 1. Depth problem. At present, during the static penetration test, it cannot be guaranteed that the static penetration depth meets the requirements. 2. Verticality problem. A common problem in static penetration tests is that the inclination angle of the probe during the penetration process cannot be obtained in real time. Therefore, it cannot be guaranteed that the probe can work within a reasonable inclination range, resulting in reduced accuracy and precision of the acquired parameters or even unusable, affecting soil layer identification. 3. If the probe deviates, a torque will be generated at the connection between the probe and the probe rod, and the greater the angle, the greater the torque, which can easily cause the probe to be scrapped or even broken due to force exceeding its bearing capacity.

[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0059] Embodiment 1

[0060] In this embodiment, as Figure 1 shown, a static cone penetration process parameter monitoring system based on multiple modules includes: a static cone penetration data acquisition module, a static cone penetration data conversion module, a static cone penetration data analysis module, a transmission module, and a terminal module.

[0061] The static cone penetration data acquisition module is used to acquire the original data of the working state of the static cone penetrometer and output an analog signal of the static cone penetration working state. The analog signal includes: a probe rod displacement signal and a probe rod inclination angle signal.

[0062] The static cone penetration data acquisition module includes: an oil pressure monitoring unit, a depth monitoring unit, and a verticality monitoring unit. The oil pressure monitoring unit is used to monitor the change of the oil pressure of the hydraulic system of the static cone penetrometer in real time; the depth monitoring unit is used to acquire the probe rod displacement signal of the probe rod of the static cone penetrometer; the verticality monitoring unit is used to acquire the probe rod inclination angle signal of the probe rod of the static cone penetrometer.

[0063] In this embodiment, the oil pressure monitoring unit is an oil pressure transmitter. Its working principle is that when pressure directly acts on the surface of the measurement diaphragm, causing a small deformation of the diaphragm, the high-precision circuit on the measurement diaphragm converts this deformation into a voltage signal proportional to the pressure. Then, a dedicated chip is used to convert this voltage signal into an industrial standard 4 to 20 mA current signal or a 1 to 5 V voltage signal. Since the hardness of different soil layers is different, that is, the resistance values received by the probe are different, and the static cone penetration test maintains a uniform motion during the penetration process, the oil pressure required to provide the power equipment is also different. Therefore, only the oil pressure data of different soil layers need to be collected during the test, and the oil pressure ranges of different soil layers are summarized to achieve the purpose of monitoring the depth data.

[0064] Among them, the depth monitoring unit includes: a displacement mounting plate, a snap ring, and a displacement sensor; as Figure 2 、 Figure 3 and Figure 4 shown, the displacement mounting plate is installed on the upper part of the lifting platform that controls the up and down displacement of the sounding rod in the penetration system; the displacement sensor is installed on the moving end of the displacement mounting plate; the snap ring is installed at the bottom of the lifting platform and is connected to the measuring head of the displacement sensor. In this embodiment, the displacement mounting plate can be a wire-drawing type displacement mounting plate, and the displacement sensor can be a wire-drawing type displacement sensor. The wire-drawing type displacement records the displacement of the penetration equipment in real time. While the wire-drawing sensor moves up and down cyclically with the lifting platform of the sounding rod, it meets the set threshold of the oil pressure sensor. Its effective displacement can be approximately regarded as composed of multiple up and down cyclic movements. The maximum displacement in each cyclic movement is denoted as s i ,the minimum displacement is denoted as s i ’.

[0065] The verticality monitoring unit can not only grasp the inclination angle in real time, but also set an early warning value (determined by the penetration depth and geological conditions, usually 8° or 10°). When the inclination angle reaches the early warning value, it can send an alarm signal and stop the static cone penetration test in time. The verticality monitoring unit is as Figure 5 shown, and includes: a connecting pipe and an inclination sensor; the connecting pipe is used to connect the sounding rod and the probe; the inclination sensor is arranged between the sounding rod and the probe and is fixed by the connecting pipe. In this embodiment, the verticality monitoring unit can include a connecting steel pipe, an irregular small module with a groove, a cover, a fixing disc, and an inclination sensor. The irregular module is as Figure 6As shown in the figure, the design requirements are as follows: (1) The upper and lower end threads of the connecting steel pipe are respectively matched with the probe rod and the probe head; (2) The module is equipped with an external thread, which is matched with the internal thread at the upper end of the connecting steel pipe, and is fixed in the middle of the connecting steel pipe by rotation, and there is a semi-circular hole with a diameter of 30 mm to allow the static penetration cable to pass through; (3) The groove matches the size of the inclination sensor, and the cover is used to seal the groove and is fixed with waterproof glue to prevent water and dust from affecting or damaging the inclination sensor; (4) The fixed disc also closely adheres to the small module by rotation to prevent the inclination sensor from being unable to maintain a horizontal position due to cable pulling.

[0066] The static penetration data conversion module is used to convert analog signals into digital signals and record the digital signals in real time. The digital signals include: probe rod displacement data and probe rod inclination angle data.

[0067] The static penetration data analysis module is used to analyze and judge the depth and verticality of the digital signals, and calculate the real-time penetration depth and verticality of the probe rod.

[0068] The static penetration data analysis module includes: a power supply device, a controller, and a on-site human-computer interaction device; the power supply device is used for long-term power supply of the static penetration data analysis module; the controller is used to analyze based on the probe rod displacement data and the probe rod inclination angle data to obtain the penetration depth and verticality, and generate a penetration depth-time change curve graph and a verticality-time change curve graph; the on-site human-computer interaction device is used to provide an interaction platform for on-site staff.

[0069] The on-site human-computer interaction device includes: a depth display unit, a threshold setting unit, a curve display unit, and a data storage unit; the depth display unit is used to display the penetration depth; the threshold setting unit is used to input the threshold of the oil pressure monitoring unit; the curve display unit is used to display the penetration depth-time change curve graph and the verticality-time change curve graph; the data storage unit is used to store the original data, the penetration depth, and the verticality.

[0070] The transmission module is used to send the original data, the penetration depth, and the verticality to the terminal module.

[0071] The transmission module includes: a switch and an intelligent gateway; the switch is used for information transmission between the on-site human-computer interaction device, the controller, and the intelligent gateway; the intelligent gateway is used to send the original data, the penetration depth, and the verticality to the terminal module. In this embodiment, the intelligent gateway uses the tcp protocol to send the data to the terminal module through the 4G / 5G network.

[0072] The terminal module is used to display the penetration depth and verticality to the management personnel in real time, and standardize the operations of on-site staff through indicator lights. In this embodiment, the terminal module can include a mobile phone terminal or a computer terminal.

[0073] Embodiment Two

[0074] In this embodiment, an application method of a static cone penetration process parameter monitoring system based on multiple modules includes the following steps:

[0075] S1. Fix an oil pressure monitoring unit at the part of the oil pipe that controls the up and down displacement of the sounding rod, fix a depth monitoring unit on the upper part of the lifting platform, and fix a verticality monitoring unit between the probe and the sounding rod.

[0076] S2. Convert the analog signal of the static cone penetration working state into a digital signal through the static cone penetration data conversion module and send it to the static cone penetration data analysis module.

[0077] S3. Through the controller, judge whether the penetration interval is valid according to the threshold value of the oil pressure monitoring unit for the digital signal, and then perform real-time input and storage. After that, calculate the real-time penetration depth and verticality of the sounding rod and draw a curve graph changing with time.

[0078] In this embodiment, the method for judging whether the penetration depth interval is valid is as follows: Analyze the data of the oil pressure monitoring system through on-site actual measurement. It can be obtained that when the static cone penetration probe is in a state without resistance, the penetration oil pressure range is 1.6 - 1.8 MPa, and when actually penetrating the soil layer, the oil pressure is generally greater than 2.3 MPa. Therefore, when calculating the depth of the wire-pulling distance sensor, the displacement stage with an oil pressure less than 2.2 MPa during the penetration state is regarded as invalid displacement and no depth calculation is performed. On the contrary, the displacement stage with an oil pressure greater than 2.2 MPa during the penetration state is regarded as valid displacement, and this interval is recorded as the effective penetration interval.

[0079] S4. Transmit the analyzed data to the human-machine interaction device and the intelligent gateway through the switch. The penetration depth, verticality, and curve graph are displayed in real time through the on-site human-machine interaction device, and the data is saved and exported in real time through the data storage unit. The intelligent gateway sends the received data to the terminal module.

[0080] S5. The management personnel monitor the working state and penetration depth of the static cone penetrometer in real time through the terminal module. When the staff finds that the working state or penetration depth of the static cone penetrometer is abnormal, they send an instruction to the on-site equipment. After receiving the instruction, the on-site human-machine interaction device prompts the on-site staff in the form of indicator light flashing.

[0081] Embodiment III

[0082] The following will introduce the specific application method of the present invention in detail through actual engineering data.

[0083] S1. Fix an oil pressure monitoring unit at the position of the oil pipe of the static cone penetrometer penetration system; fix a wire-pulling displacement monitoring unit on the upper part of the lifting platform that controls the up and down displacement of the penetration system, and fix a wire sensor at the lower part of the lifting platform with a snap ring; fix a verticality monitoring unit between the sounding rod and the probe.

[0084] S2. Convert the analog signals collected by the piezocone data acquisition module into digital signals through the information conversion module and send them to the piezocone depth measurement module.

[0085] S3. Use the controller to determine whether the penetration interval is valid according to the threshold of the oil pressure monitoring unit for the digital signals, and then perform real-time input and storage. After that, calculate the real-time penetration depth and verticality of the sounding rod and draw a curve graph that changes with time, as Figure 7 、 Figure 8 and Figure 9 shown.

[0086] After analyzing a large amount of data obtained on-site, by comparing the oil pressure with the soil layer information of this project, it can be seen from Figure 8 that six penetration stages can be clearly distinguished according to the change of oil pressure. The oil pressures in stage Ⅰ, stage Ⅱ, stage Ⅲ, stage Ⅳ, stage Ⅴ and stage Ⅵ are different. Among them, during the penetration process in stage Ⅰ, the oil pressure range is 2.5 - 2.7 MPa, in stage Ⅱ the oil pressure range is 2.7 - 3.3 MPa, in stage Ⅲ the oil pressure range is 2.55 - 2.8 MPa, in stage Ⅳ the oil pressure range is 3.6 - 3.9 MPa, in stage Ⅴ the oil pressure range is 3.3 - 3.7 MPa, and the oil pressure range in stage Ⅵ is 4 - 6 MPa. It is obvious that the oil pressure ranges of different soil layers are different, and there is a certain similarity relationship with the hardness of the soil layer, which can achieve the purpose of monitoring the authenticity of the depth. Although each engineering geological layer group and sub-layer cannot be specifically distinguished, typical soil layers can be roughly distinguished. Through the above analysis of the oil pressure, it can be obtained that when the piezocone probe is in a state without resistance, the penetration oil pressure range is 1.6 - 1.8 MPa, and when it is in the real state of penetrating the soil layer, the oil pressure is generally greater than 2.3 MPa. Therefore, when calculating the depth of the pull-wire distance sensor, the displacement stage with an oil pressure less than 2.2 MPa during the penetration state is regarded as an invalid displacement and no depth calculation is performed. On the contrary, the displacement stage with an oil pressure greater than 2.2 MPa during the penetration state is regarded as a valid displacement, and this interval is recorded as the effective penetration interval.

[0087] In its effective displacement stage, it can be approximately regarded as composed of multiple cyclic motions of moving up and down. In each cyclic motion, the maximum displacement is denoted as s i , and the minimum displacement is denoted as s i '. Among them, i is the i-th cyclic motion, the depth is represented by d, and the oil pressure during the penetration state is denoted as o. Then the calculation formula for the piezocone hole depth is:

[0088]

[0089] Draw the data into a curve graph that changes with time, and write the above content into the controller in the form of programming language for real-time calculation of the penetration depth of the sounding rod.

[0090] S4. Transmit the data analyzed by the controller to the on-site human-machine interaction device and the intelligent gateway through the switch. In the on-site human-machine interaction device, the real-time depth value, the values of each monitoring module, and the curve graph of various data changing with time can be seen in real time, and the data can be saved and exported in real time through the data saving module; after receiving the data, the intelligent gateway uses the TCP protocol to communicate directly with the mobile phone side and the computer side through the 4G / 5G network.

[0091] S5. The staff can monitor the working state of the static penetrometer and the penetration depth of the static penetration rod in real time on the mobile phone side and the computer side. When the staff finds that the working state of the static penetrometer or the depth display is abnormal, they can send instructions to the on-site equipment. After receiving the instructions, the on-site equipment will prompt the staff of the static penetrometer in the form of indicator light flashing.

[0092] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
