[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0030] Screw pile is often used to support a sensory integrated pole. Generally, the screw pile is driven into the ground and used as an anchor point for the sensory integrated pole. To ensure the stability of the sensory integrated pole, the screw pile must be installed to an appropriate depth and geological stratum. After installation, the screw pile is subjected to various artificial and natural forces. For example, earthquakes, wind, underground water and changing geological strata can generate natural loads. These forces can exert torsional, lateral, axial (tensile and compressive) and combined loads on the screw pile. In some cases, these forces can exceed the load that the screw pile can bear. Therefore, it is necessary to detect the screw pile.

[0031] In the prior art, due to the large amount and wide range of arrangement of the sensory integrated pole, the detection of the screw pile is usually carried out in a sampling inspection manner. The prior art has the problem that sampling inspection is not complete, which causes the sensory integrated pole to exist in a dangerous working condition, and thus safety accidents are prone to occur. To this end, the embodiments of the present application propose an intelligent sensing system for a screw pile, which aims to solve the above technical problems.

[0032] In combination with Figs. 1 to 4 The embodiments of the present application propose an intelligent sensing system for a screw pile 10. The screw pile 10 includes a hollow tubular body 110 having an outer surface, helical blades 120 arranged at intervals along the axial direction of the hollow tubular body 110, and a grouting passage S1 provided in the hollow tubular body. In the embodiments, the screw pile 10 is drilled into the stratum by a drilling machine, and then mud is injected into the stratum through the grouting passage S1. The slurry is transported from the grouting passage to the grouting hole position of the hollow tubular body 110, fills the gap between the pile and the soil, and is pressed into the soil gap within a certain range around the grouting hole. This can improve the side resistance and end resistance of the screw pile 10, so that the formed pile has high bearing capacity and resistance to deformation, reduces the settlement of the pile, improves the supporting capacity of the screw pile 10, and can improve the stability of the sensory integrated pole 160 supported by the screw pile 10.

[0033] The intelligent sensing system includes:

[0034] A sensory integrated pole 160 supported by the screw pile 10;

[0035] a plurality of data cables 150, which are electrically connected with the perception integrated rod 160; the hollow tubular body 110 is further provided with a cable channel S2 which is separate from the grouting channel S1; the plurality of data cables 150 are arranged in the cable channel S2;

[0036] a plurality of sensors 20, which are attached to the tubular body 110 of the outer surface; and at least one sensor is arranged between every two adjacent spiral blades 120; each sensor is electrically connected with one of the plurality of data cables 150 to upload the perception data collected by the sensor to the perception integrated rod 160; and

In the embodiment, the perception integrated rod 160 is arranged in a natural environment, and the number of the perception integrated rods 160 arranged is wide. The embodiment of the present application utilizes the perception integrated rod 160 to perceive external information while intelligently monitoring the spiral pile foundation 10 where the perception integrated rod 160 is located, and then analyzes whether the spiral pile foundation 10 is in a dangerous working condition. The perception integrated rod 160 obtains the bearing working condition of the spiral pile foundation 10 through analysis of the perception data; if the bearing working condition triggers one or more of a plurality of early warning conditions, the bearing working condition is sent to the server 180, and the server 180 generates order information according to the bearing working condition, which is used to instruct on-site exploration or on-site maintenance of the spiral pile foundation 10, so as to reduce the occurrence of safety accidents.

[0039] In the technical scheme of the embodiment of the present application, the cable 150 of the sensor has a separate cable channel S2, and does not share the channel with the grouting channel S1, which can avoid damage to the cable 150 in the grouting process, and thus can improve the accuracy and timeliness of the perception data transmission, and can improve the effectiveness of the intelligent monitoring of the spiral pile foundation 10.

[0040] In an embodiment, the screw pile 10 is also connected with a support part 170 on the ground. The support part can be a tower structure or a column structure. A sensing integrated pole 160 is installed on the support part.

Of course, those skilled in the art will recognize that the computer storage media described above can be embodied in any computer-readable media. The system memory and the mass storage device described above can be collectively referred to as memory.

That is, the perception integrated rod can be connected to a network through a network interface unit connected to the system bus, or in other words, a network interface unit can also be used to connect to other types of network or remote computer system (not shown).

[0046] In some embodiments, the plurality of sensors 20 includes a plurality of mechanical sensors; the plurality of mechanical sensors is divided into at least two groups. Each group of mechanical sensors includes a stress sensor 132, a strain sensor 131 and a displacement sensor 133. The at least two groups of mechanical sensors are arranged at different axial positions of the hollow tubular body 110, and the helical blades 120 are arranged between the two groups of mechanical sensors which are axially adjacent. In the embodiments of the present application, the groups of mechanical sensors are arranged at different axial positions of the hollow tubular body 110 for analyzing the external loads applied to the screw pile 10 at different depths. These external loads can be torque, bending moment, pressure, etc. Each group of mechanical sensors includes stress, strain and displacement sensors 133 to collect complex loads applied at different axial positions, so as to facilitate the perception integrated rod 160 to analyze the complex working conditions of the screw pile 10 in real time.

[0047] The helical blades 120 play a role in improving the stability of the screw pile 10 in the screw pile 10, so in the embodiments, the helical blades 120 are arranged between the two groups of mechanical sensors which are axially adjacent. Therefore, the technical scheme of the embodiments of the present application can at least collect the stress, strain and displacement of the segments of the hollow tubular body 110 separated by the helical blades 120, so as to facilitate the determination of the bearing capacity of the screw pile 10.

[0048] In specific embodiments, mechanical sensors are arranged between adjacent helical blades 120.

[0049] In some embodiments, the stress sensor 132, the strain sensor 131 and the displacement sensor 133 in the same group of mechanical sensors are arranged at intervals along the ring direction of the hollow tubular body 110 and are located at the same height position of the hollow tubular body 110. That is, in the embodiments, the stress sensor 132, the strain sensor 131 and the displacement sensor 133 of the same group of mechanical sensors are arranged at the same cross-sectional position of the hollow tubular body 110 and are arranged at intervals along the ring direction, so as to collect the stress information at a cross section.

[0050] In some embodiments, the perception integrated rod 160 is configured to: obtain, according to the perception data of the same group of mechanical sensors, the mechanical analysis result of the pipe segment of the hollow tubular body 110 perceived by the group of mechanical sensors; obtain, according to the mechanical analysis results of different groups, the mechanical analysis result of the screw pile foundation 10; the plurality of early warning conditions include a first stress early warning condition, and if the mechanical analysis result of the screw pile foundation 10 triggers the first stress early warning condition, the mechanical result of the screw pile foundation 10 is uploaded to the server 180.

[0051] For example, in an embodiment, the strain collected at the i height is ε hi , the stress is σ hi , and the displacement is Σ hi ; when the server 180 collects the strain, stress, and displacement at different heights, it respectively transmits them to the preset strain calculation model f ε , stress calculation model f σ , and displacement calculation model f Σ to respectively calculate the strain level, stress level, and displacement level of the screw pile foundation 10. The first stress early warning condition includes a first strain early warning value, a first stress early warning value, and a first displacement early warning value. If the strain level exceeds the first strain early warning value or the stress level exceeds the first stress early warning value or the displacement level exceeds the first displacement early warning value, the mechanical result of the screw pile foundation 10 is uploaded to the server 180.

[0052] In an embodiment, the strain calculation model f ε , the stress calculation model f σ , and the displacement calculation model f Σ may be a theoretical model, an experimental model obtained by experimental testing, or a network model obtained by network training of big data.

[0053] In an embodiment, the mechanical conditions of different pipe segments are mainly measured to evaluate the bearing capacity of the screw pile foundation 10 as a whole to analyze whether the screw pile foundation 10 as a whole is in a dangerous working condition.

[0054] In some embodiments, the plurality of early warning conditions includes a second force early warning condition, and the perception integrated rod 160 is configured to: if the mechanical analysis result of the pipe section of the hollow tubular body 110 sensed by a certain group of mechanical sensors triggers the second force early warning condition, then upload the mechanical analysis result of the pipe section of the hollow tubular body 110 sensed by the certain group of mechanical sensors and the position information of the pipe section of the hollow tubular body 110 sensed by the certain group of mechanical sensors to the server 180. That is, in the embodiments of the present application, if the mechanical analysis result of a certain section triggers the second force early warning condition, the mechanical analysis result and the position information of the section also need to be sent to the server 180. For example, if the strain of a certain hollow tubular body 110 exceeds the second strain early warning value, or the stress exceeds the second stress early warning value, or the displacement exceeds the second displacement early warning value, the mechanical analysis result and the position information of the section are sent to the server 180. In this embodiment, the local load bearing condition of the screw pile foundation 10 is mainly evaluated in danger to be able to timely find out whether the local screw pile foundation 10 is overloaded and the position of the overloaded screw pile foundation 10, so as to facilitate maintenance and repair; for example, through this embodiment, it can be found that a certain local pipe section is subjected to impact external load.

[0055] In some embodiments, the plurality of sensors 20 further includes: a plurality of environmental sensors, each group of the mechanical sensors is correspondingly provided with at least one of the plurality of environmental sensors. In the technical solution of the embodiments of the present application, the environmental parameters in which the screw pile foundation 10 is located can be fully reflected, such as the water content and temperature of the soil layer; and each group of mechanical sensors is correspondingly provided with an environmental sensor, so as to analyze the environment in which the hollow tubular body 110 sensed by the group of mechanical sensors is located, thereby facilitating analysis of whether the abnormal bearing working condition is caused by the soil environment.

[0056] In some embodiments, the warning conditions further include a third warning condition, and the perception integrated rod 160 is configured to generate an environment analysis result based on the perception data of the plurality of environment sensors, and upload the environment analysis result to the server 180 if the environment analysis result triggers the third warning condition. By analyzing the environment perception data, it is analyzed whether the environment of the stratum triggers the third warning condition. For example, if an environment parameter exceeds its corresponding preset parameter, the environment parameter is sent to the server 180. For example, in an embodiment, the plurality of environment sensors include at least one of a temperature sensor 141, a humidity sensor 142, or a PH sensor. When the humidity data collected by the humidity sensor 142 exceeds the preset humidity value, it indicates that the water content in the soil layer exceeds the standard, and at this time the stratum may be loose and the screw pile foundation 10 may be unstable; when the PH sensor measures that the soil is acidic or alkaline, it may cause the corrosion speed of the screw pile foundation 10 to increase, and the screw pile foundation 10 may be corroded and damaged; when the temperature sensor 141 measures that the temperature of the soil is too high or too low, it may cause the physical properties of the soil such as internal friction and viscosity to change, and it may also cause the screw pile foundation 10 to be in a dangerous working condition.

[0057] Further, in some embodiments, the warning conditions further include a fourth warning condition, and the perception integrated rod 160 is configured to generate an environment analysis result based on the perception data of the plurality of environment sensors, obtain a mechanical analysis result of the pipe segment of the hollow tubular body 110 perceived by the same group of mechanical sensors according to the perception data of the same group of mechanical sensors; and send the environment analysis result and the mechanical analysis result to the server 180 together if the mechanical analysis result triggers the fourth warning condition corresponding to the environment analysis result. For example, when the humidity value corresponding to a group of mechanical sensors is 85%, the strain level, stress level, or displacement level measured by the group of mechanical sensors exceeds the third strain warning value, the third stress warning value, or the third displacement warning value corresponding to 85%, the humidity value 85% and one or more of the strain level, stress level, and displacement level that exceed the corresponding warning value are sent to the server 180 together; for another example, when the PH value corresponding to a group of mechanical sensors is 4, the strain level, stress level, or displacement level measured by the group of mechanical sensors exceeds the fourth strain warning value, the fourth stress warning value, or the fourth displacement warning value corresponding to the PH value 4, the PH value 4 and one or more of the strain level, stress level, and displacement level that exceed the corresponding warning value are sent to the server 180 together.

[0058] That is, in the technical solution of the embodiment of the application, the preset parameters for judging the mechanical analysis result, the preset parameters for judging the environmental analysis result, and the preset parameters for fusing the environmental analysis result and the mechanical analysis result are preset in the comprehensive sensing rod 160, so as to fully reflect the bearing working condition of the screw pile foundation 10.

[0059] In some embodiments, the order information includes vibration test information for instructing to perform vibration test on the screw pile foundation 10. The plurality of sensors 20 includes a plurality of vibration sensors 190 for detecting vibration signals generated by the surrounding structure of the screw pile foundation 10 when vibration is applied to the structure in which the screw pile foundation 10 is located. The comprehensive sensing rod 160 is configured to evaluate the bearing capacity of the screw pile foundation 10 based on the vibration signals and generate an evaluation result, which is uploaded to the server 180 and / or a terminal device authorized by the server 180. The vibration sensor 190 can be an acceleration sensor, a speed sensor, or a displacement sensor 133. That is, when the comprehensive sensing rod measures that the screw pile foundation 10 is in a dangerous working condition, the server 180 is sent the dangerous working condition, and the server 180 generates vibration test information based on the dangerous working condition for instructing the worker to go to the geographical location of the screw pile foundation 10, and then tests the screw pile foundation 10 by applying vibration on the ground. The displacement, stress, and strain trends over time and vibration frequency are collected by the sensor. These trends are displayed on the server 180 or a terminal device authorized by the server 180 for evaluating the bearing capacity of the screw pile foundation 10. The evaluation result can include various display forms such as charts, curves, and / or text.

[0060] Through the technical solution of the embodiment of the application, the screw pile foundation can be detected without using the sampling inspection method, but by intelligently sensing the bearing working condition of the screw pile foundation to determine whether the screw pile foundation needs to be detected.
