Description

Technical Field

[0001] The present application belongs to the technical field of foundation detection, and in particular, relates to a building foundation bearing capacity detection device and a detection method. Background Art

[0002] Foundation bearing capacity testing refers to testing the mechanical properties of soil or foundation to determine the bearing capacity of soil, thereby providing a basis for the design and safety of other structures such as buildings and foundation engineering. Common foundation bearing capacity testing methods include static load test method, dynamic penetration test method, rebound method, etc. Among them, static load test method is a relatively common and efficient testing method, which mainly sets up testing equipment on the foundation to be tested so that the testing equipment can directly measure the foundation bearing capacity. The existing static load test method only detects the bearing capacity at one stress point of the foundation to be tested, which is prone to detection errors, so multi-point detection is required. When performing multi-point detection, it is necessary to manually move and adjust the detection equipment, which is time-consuming and labor-intensive.

[0003] Therefore, the existing building foundation bearing capacity detection equipment has the problem of low detection efficiency. Summary of the invention

[0004] The present application provides a building foundation bearing capacity detection device and a detection method for improving the detection efficiency of the foundation bearing capacity.

[0005] In the first aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A building foundation bearing capacity detection device, comprising: A vehicle body, wherein a crawler track is arranged at the bottom of the vehicle body, and a driving arm of the vehicle body is provided with a hydraulic telescopic rod; A linkage member, fixedly connected to the telescopic end of the hydraulic telescopic rod; A fixing member, used to bear against the surface of the foundation to be measured; A connecting member, the connecting member passes through and is slidably connected to the linkage member, one end of the connecting member away from the linkage member is connected to the fixing member, at least four connecting members are provided, and the multiple connecting members are evenly spaced; A spring, sleeved on the connecting member, one end of the spring abuts against the linkage member, and the other end of the spring abuts against the fixing member; A pressure-sensitive sensor for an external reading device, wherein the pressure-sensitive sensor is arranged on a side of the fixing member close to the linkage member.

[0006] Through the above technical scheme, when the inspector needs to inspect the surface of the foundation to be inspected, the inspector can sit in the vehicle body, manipulate the vehicle body to move near the foundation to be inspected, and then drive the driving arm and hydraulic telescopic rod of the vehicle body to make the fixing part press against the surface of the foundation to be inspected, and make the spring sleeved on the connecting part contract, so that the linkage part presses the pressure-sensitive sensor. When the surface of the foundation to be inspected is deformed to a certain extent, the pressure value output by the pressure-sensitive sensor to the reading device is equal to the bearing capacity of the foundation. Compared with the prior art, the equipment of the present application increases the force-bearing area of ​​the point to be measured through the fixing part, thereby improving the detection accuracy. The pressure-sensitive sensor does not contact the surface of the foundation to be measured, thereby reducing the influence of soil properties on the detection effect. In addition, the equipment of the present application can flexibly detect each point to be measured on the surface of the foundation to be measured, thereby improving the detection efficiency of the foundation bearing capacity.

[0007] The present application is further configured as follows: the linkage member is disc-shaped, at least four distance measuring sensors are evenly spaced on the outer circumference of the linkage member, and the distance measuring sensors are used to measure the relative distance between the linkage member and the surface of the foundation to be measured.

[0008] Through the above technical scheme, the disc-shaped linkage part has the characteristics of easy processing and strong bearing capacity; at least four distance measuring sensors are arranged at intervals on the outer periphery of the linkage part to measure the relative distance between the linkage part and the surface of the foundation to be measured, and then the inclination angle of the fixing part relative to the surface of the foundation to be measured is calculated based on multiple relative distances, thereby assisting the detection personnel to adjust the inclination angle of the fixing part so that the fixing part can fit horizontally to the surface of the foundation to be measured, so that the pressure-sensitive sensor is evenly stressed, thereby improving the detection accuracy of the foundation bearing capacity.

[0009] The present application is further configured as follows: the fixing member is disc-shaped, a groove is provided at the center of the fixing member, the pressure-sensitive sensor is arranged in the groove, and a first protrusion for squeezing the pressure-sensitive sensor is provided at the center of the linkage member.

[0010] Through the above technical scheme, the disc-shaped fixing part has the characteristics of easy processing and strong bearing capacity; the groove is used to limit the movement of the pressure sensitive sensor relative to the fixing part, and the first protrusion is used to press the pressure sensitive sensor when detecting the surface of the foundation to be tested; compared with the prior art, the pressure sensitive sensor is located at the geometric center of the fixing part, so that the force on the pressure sensitive sensor is more uniform, thereby further improving the detection accuracy of the foundation bearing capacity.

[0011] The present application is further configured as follows: a plurality of second protrusions are provided at the bottom of the fixing member, the plurality of second protrusions are evenly spaced along the outer circumference of the fixing member, and the second protrusions are made of tungsten steel material.

[0012] Through the above technical scheme, the second protrusions made of tungsten steel material have high hardness and can bear greater pressure; when the fixing piece is against the surface of the foundation to be measured, multiple second protrusions can increase the pressure on the surface of the foundation to be measured, so that the detection personnel can intuitively observe the deformation degree of the surface of the foundation to be measured; and the second protrusions are evenly spaced, which is conducive to making the bottom side of the fixing piece evenly stressed, so that the pressure-sensitive sensor is also evenly stressed.

[0013] In the second aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A method for detecting the bearing capacity of a building foundation, applied to the above-mentioned device for detecting the bearing capacity of a building foundation, the method comprising: Sending a driving signal to the driving arm of the vehicle body and the hydraulic telescopic rod to move the fixing member to the position just above the surface of the foundation to be measured; Acquire a plurality of relative distance signals emitted by a plurality of the distance measuring sensors; Based on the plurality of relative distance signals, calculating the inclination angle of the fixing member relative to the surface of the foundation to be measured; If the tilt angle is less than a preset angle threshold, a loading signal is sent to the hydraulic telescopic rod so that the fixing member is pressed against the surface of the foundation to be measured and the linkage member squeezes the pressure-sensitive sensor; Receive the foundation bearing capacity detection signal sent by the pressure-sensitive sensor.

[0014] Through the above technical scheme, a driving signal is first sent to the driving arm of the vehicle body and the hydraulic telescopic rod to move the fixed part to the top of the foundation surface to be measured, and then multiple relative distance signals are obtained through multiple distance measuring sensors, and the inclination angle of the fixed part relative to the foundation surface to be measured is calculated according to the multiple relative distance signals. When the inclination angle is less than the preset angle threshold, it means that the fixed part is parallel to the foundation surface to be measured, and then a loading signal is sent to the hydraulic telescopic rod to make the linkage part drive the fixed part to descend. When the fixed part is against the foundation surface to be measured, the hydraulic telescopic rod gradually applies pressure to the linkage part, so that the linkage part slides on multiple connecting parts. When the linkage part presses the pressure-sensitive sensor, the pressure-sensitive sensor sends a foundation bearing capacity detection signal. Compared with the prior art, the method of the present application can automatically detect multiple foundation surface nodes to be measured, and has higher detection efficiency.

[0015] The present application is further configured as follows: after calculating the inclination angle of the fixing member relative to the surface of the foundation to be measured based on the plurality of relative distance signals, the method further comprises: If the tilt angle is greater than a preset angle threshold, a correction signal is sent to the driving arm of the vehicle body, and after the tilt angle is less than the preset angle threshold, a loading signal is sent to the hydraulic telescopic rod.

[0016] Through the above technical scheme, when the tilt angle is greater than the preset angle threshold, it means that the fixing part is not parallel to the surface of the foundation to be measured. At this time, a correction signal is sent to the driving arm of the vehicle body until the tilt angle is less than the preset angle threshold, and then a loading signal is sent to the hydraulic telescopic rod to improve the detection accuracy of each detection of the surface node of the foundation to be measured; compared with the prior art, the method of the present application has the function of automatically correcting the fixing part to make the pressure-sensitive sensor evenly stressed, and has higher detection accuracy; and the method of the present application realizes automatic correction, which further improves the detection efficiency.

[0017] The present application is further configured as follows: after receiving the foundation bearing capacity detection signal emitted by the pressure-sensitive sensor, the method further includes: If the foundation bearing capacity detection signal is higher than the bearing capacity threshold, the position information of the fixing part is recorded and a compliance signal is issued.

[0018] Through the above technical solution, when the foundation bearing capacity detection signal is higher than the bearing capacity threshold, it means that the surface node of the foundation to be tested has reached the bearing capacity index, and a compliance signal is issued and the position information of the fixing parts is recorded to assist the detection personnel in verification and avoid repeated detection of the same node.

[0019] In the third aspect, the invention objective of the present application is achieved by adopting the following technical solutions: A building foundation bearing capacity detection system, using the above-mentioned building foundation bearing capacity detection method, the system comprises: A driving module, used for sending a driving signal to the driving arm of the vehicle body and the hydraulic telescopic rod, so that the fixing member moves to the position just above the surface of the foundation to be measured; A distance signal acquisition module, used to acquire a plurality of relative distance signals emitted by a plurality of the distance measuring sensors; An angle calculation module, used for calculating the inclination angle of the fixing member relative to the surface of the foundation to be measured based on the plurality of relative distance signals; A loading module, used for sending a loading signal to the hydraulic telescopic rod if the tilt angle is less than a preset angle threshold, so that the fixing member is pressed against the surface of the foundation to be measured, and the linkage member squeezes the pressure-sensitive sensor; The foundation bearing capacity signal receiving module is used to receive the foundation bearing capacity detection signal sent by the pressure-sensitive sensor.

[0029] Embodiment 1 The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0030] The embodiments of the present application provide a building foundation bearing capacity detection device and a detection method to improve the detection efficiency of the foundation bearing capacity.

[0031] Embodiment 1 like Figure 1 and Figure 2 As shown, a construction foundation bearing capacity detection device of an embodiment of the present application includes a vehicle body 1, a linkage member 2, a fixing member 3, four connecting members 4, four springs 5 ​​and a pressure-sensitive sensor 6; in this embodiment, the vehicle body 1 uses an existing existing excavator, which has a crawler 11 and a driving arm 12, and is suitable for traveling and working in a muddy construction site; a hydraulic telescopic rod 13 is provided at the end of the driving arm 12, and the linkage member 2 is fixedly connected to the telescopic end of the hydraulic telescopic rod 13; four connecting members 4 are evenly spaced around the outer edge of the linkage member 2, the connecting member 4 passes through and is slidably connected to the linkage member 2, and one end of the connecting member 4 away from the linkage member 2 is threadedly connected to the fixing member 13. Part 3, so that when the hydraulic telescopic rod 13 is extended and retracted, the linkage part 2 drives the fixed part 3 to perform lifting movement through the connecting part 4; four springs 5 ​​are respectively mounted on the rod body of the connecting part 4, and one end is against the linkage part 2, and the other end is against the fixed part, so that when the fixed part 3 does not resist the surface of the foundation to be measured, the linkage part 2 and the fixed part 3 are stretched apart; the pressure-sensitive sensor 6 is arranged on the side of the fixed part 3 close to the linkage part 2, so that when the fixed part 3 resists the surface of the foundation to be measured, the foundation bearing capacity of the corresponding point on the surface of the foundation to be measured is indirectly measured by detecting the clamping force between the linkage part 2 and the fixed part 3; the pressure-sensitive sensor 6 is externally connected to a reading device to realize data visualization.

[0032] Compared with the prior art, the device of the present application increases the force-bearing area of ​​the point to be measured through the fixing part 3, thereby improving the detection accuracy; and, when detecting the surface of the foundation to be measured, the device of the present application separates the pressure-sensitive sensor 6 from the surface of the foundation to be measured, thereby avoiding the possibility of soil flow on the surface of the foundation to be measured eroding the pressure-sensitive sensor 6, thereby further improving the detection accuracy; in addition, the detection personnel can drive the vehicle body 1 to flexibly detect various points on the surface of the foundation to be measured, thereby improving the detection efficiency of the foundation bearing capacity.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the device of the present application also includes four distance measuring sensors 7 for detecting the relative distance between the linkage member 2 and the surface of the foundation to be measured; the linkage member 2 is disc-shaped, which is convenient to produce and process and has a high bearing capacity; the four distance measuring sensors 7 are evenly and spaced along the outer circumference of the linkage member 2, so as to facilitate respectively detecting the relative distances between the four parts of the linkage member 2 and the surface of the foundation to be measured, and indirectly obtain the inclination angle of the linkage member 2 and the fixing member 3 relative to the surface of the foundation to be measured, so as to assist the detection personnel in finding the level, so that the fixing member 3 can be horizontally attached to the surface of the foundation to be measured, so that the pressure-sensitive sensor 6 is evenly stressed, thereby further improving the detection accuracy of the foundation bearing capacity.

[0034] In this embodiment, the linkage member 2 is made of tungsten steel, which has good corrosion resistance and structural strength.

[0035] Reference Figure 1 and Figure 2 The fixing member 3 is also disc-shaped, and has the characteristics of easy processing and strong bearing capacity. A circular groove 31 is provided at the center of the fixing member 3, and the pressure-sensitive sensor 6 is arranged in the groove 31. The groove 31 is used to fix the position of the sensor to reduce the possibility that the pressure-sensitive sensor 6 is offset due to the lateral external force or component force and affects the detection. The linkage member 2 is provided with a first protrusion 21 for squeezing the pressure-sensitive sensor 6 at the position corresponding to the groove 31. When the fixing member 3 is against the surface of the foundation to be measured, the hydraulic telescopic rod 13 applies pressure to the linkage member 2, so that the linkage member 2 is relative to the connecting member 4. Slide and make the first protrusion 21 squeeze the pressure sensitive sensor 6, so that the pressure sensitive sensor 6 is evenly stressed, and the foundation bearing capacity of each point on the foundation surface to be measured is detected more accurately; a plurality of second protrusions 32 made of tungsten steel are arranged at the bottom of the fixing member 3, which are used to increase the pressure of the fixing member 3 on the foundation surface to be measured, so that the detection personnel can intuitively observe the deformation degree of the foundation surface to be measured when pressure is applied; a plurality of second protrusions 32 are evenly spaced along the outer circumference of the fixing member 3, so that the bottom side of the fixing member 3 is evenly stressed, and then the pressure sensitive sensor 6 is evenly stressed, further improving the detection accuracy.

[0036] The principles implemented in the embodiments of the present application are as follows: When the inspector needs to inspect the surface of the foundation to be inspected, the inspector sits in the vehicle body 1, manipulates the vehicle body 1 to move near the foundation to be inspected, and then drives the driving arm 12 and the hydraulic telescopic rod 13 of the vehicle body 1 to make the fixing part 3 press against the surface of the foundation to be inspected, and make the spring 5 sleeved on the connecting part 4 contract, so that the linkage part 2 presses the pressure-sensitive sensor 6. When the surface of the foundation to be inspected is deformed to a certain extent, the pressure value output by the pressure-sensitive sensor 6 to the reading device is equal to the bearing capacity of the foundation.

[0037] Embodiment 2 like Figure 3 As shown, the embodiment of the present application discloses a method for detecting the bearing capacity of a building foundation, which is applied to a building foundation bearing capacity detection device in embodiment 1. The method of the present application includes: S10: Sending a driving signal to the driving arm and the hydraulic telescopic rod of the vehicle body to move the fixing member to the position just above the surface of the foundation to be measured.

[0038] In this embodiment, the inspector can manipulate the vehicle body from within the vehicle body or through a remote controller.

[0039] Specifically, the inspector manipulates the vehicle body through a controller inside the vehicle body, and sends a driving signal to the driving arm and the hydraulic telescopic rod, so that the fixing part rotates and moves until it moves to just above the surface of the foundation to be tested.

[0040] S20: Acquire multiple relative distance signals sent by multiple distance measuring sensors.

[0041] Specifically, a controller in the vehicle body or an external computer device obtains multiple relative distance signals.

[0042] S30: Calculating the inclination angle of the fixing member relative to the surface of the foundation to be measured based on the multiple relative distance signals.

[0043] Specifically, the external computer device calculates the spatial angle of the fixing member relative to the surface of the foundation to be measured as the inclination angle based on the existing spatial angle calculation method and the Pythagorean theorem through multiple relative distance signals.

[0044] After step S30, the method of the present application further includes: If the tilt angle is greater than the preset angle threshold, a correction signal is sent to the driving arm of the vehicle body, and a loading signal is sent to the hydraulic telescopic rod until the tilt angle is less than the preset angle threshold.

[0045] In this embodiment, the angle threshold is 5 degrees; the deviation correction signal can be automatically sent to the driving arm of the vehicle body by the computer device after calculation and judgment.

[0046] Specifically, when the tilt angle is greater than the preset 5 degrees, it means that the fixing part is not parallel to the surface of the foundation to be measured. The inspector sends a correction signal to the driving arm of the vehicle body through the controller to make the tilt angle less than 5 degrees, and then sends a loading signal to the hydraulic telescopic rod. The hydraulic telescopic rod descends, so that the linkage part presses the pressure-sensitive sensor under the premise of being level with the surface of the foundation to be measured, thereby improving the detection accuracy of each detection of the surface node of the foundation to be measured; compared with the prior art, the method of the present application has the function of automatically correcting the fixing part to make the pressure-sensitive sensor evenly stressed, and has higher detection accuracy.

[0047] S40: If the tilt angle is less than a preset angle threshold, a loading signal is sent to the hydraulic telescopic rod so that the fixing member is pressed against the surface of the foundation to be measured and the linkage member squeezes the pressure-sensitive sensor.

[0048] In this embodiment, when the inclination angle is less than 5 degrees, it indicates that the fixing member is parallel to the surface of the foundation to be measured.

[0049] Specifically, when the inclination angle is less than the preset angle threshold, a loading signal is sent to the hydraulic telescopic rod, so that the linkage part drives the fixed part to descend. When the fixed part is against the surface of the foundation to be measured, the hydraulic telescopic rod gradually applies pressure to the linkage part, causing the linkage part to slide on multiple connecting parts. When the linkage part presses the pressure-sensitive sensor, the pressure-sensitive sensor sends a foundation bearing capacity detection signal.

[0050] S50: receiving a foundation bearing capacity detection signal sent by a pressure-sensitive sensor.

[0051] Specifically, a reading device external to the pressure-sensitive sensor reads the foundation bearing capacity detection signal and sends it to a computer processing device.

[0052] Compared with the prior art, the method of the present application can automatically detect and read multiple surface nodes of the foundation to be measured, and has higher detection efficiency.

[0053] After step S50, the method of the present application further includes: If the foundation bearing capacity detection signal is higher than the bearing capacity threshold, the position information of the fixing parts is recorded and a compliance signal is issued.

[0054] It should be noted that when the inspectors in the vehicle body inspect the surface of the foundation to be tested, auxiliary personnel are also required to observe the deformation of the surface of the foundation to be tested to avoid overpressure.

[0055] Specifically, when the foundation bearing capacity detection signal is higher than the bearing capacity threshold, the computer equipment automatically records the position information of the fixing to indicate that the detection is completed at that position; at the same time, the computer equipment also sends a compliance signal to indicate that the foundation bearing capacity of the node meets the standard, thereby assisting the detection personnel in verification.
