Description

Technical Field

[0001] The present invention relates to the technical field of foundation detection, in particular to a water conservancy project foundation detection device. Background Art

[0002] As a vital component of national infrastructure, the safety, stability, and long-term operation of water conservancy projects are directly linked to the national economy and people's livelihood. Water conservancy project foundation testing is a critical step in ensuring the overall quality and safety of water conservancy projects. Comprehensive and systematic foundation testing provides a deep understanding of the foundation's physical properties, such as the distribution of soil layers and particle composition; its mechanical properties, such as the elastic modulus and Poisson's ratio; and the identification of potential engineering risks, such as underground cavities and weak interlayers. This information provides crucial support for the design, construction, and operation of water conservancy projects.

[0003] Among the various indicators tested for water conservancy project foundations, bearing capacity, shear strength, and peak torque are key indicators for evaluating foundation stability and safety. Bearing capacity determines the foundation's ability to withstand superstructure loads, shear strength affects the foundation's ability to resist shear failure, and peak torque is closely related to the foundation's stability under torque. Accurate testing of these key indicators can promptly identify potential foundation risks, allowing appropriate reinforcement or treatment measures to ensure the safety of the building structure.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Reference Figure 1-4 The present invention provides a water conservancy project foundation detection device, comprising:

[0049] An engineering vehicle 1 is provided with adjustable positioning legs 2;

[0050] The sampling mechanism includes a test frame body 3, an angle adjustment component is installed on the engineering vehicle 1, the test frame body 3 is installed on the angle adjustment component, a mounting plate 4 is vertically slidably connected to the test frame body 3, a height adjustment component is installed on the test frame body 3, the mounting plate 4 is installed on the height adjustment component, a mounting platform 5 is horizontally slidably connected to the mounting plate 4, a horizontal position adjustment component is provided between the mounting platform 5 and the mounting plate 4, a sampling component is installed on the mounting platform 5, and a shear plate is installed in the sampling tube 15 of the sampling component;

[0051] A bearing capacity detection mechanism includes a winding motor 6 fixed to the engineering vehicle 1, a guide support assembly is installed on the top of the test frame body 3, a winding roller is installed on the winding motor 6, and a steel wire is wound around the winding roller. One end of the steel wire passes through the guide support assembly and is fixed to a counterweight block;

[0052] The terminal system is used to collect test data.

[0053] During operation, after the engineering vehicle 1 reaches the water conservancy project foundation inspection location, the adjustable positioning legs 2 are adjusted to stably secure the engineering vehicle 1 to the ground, providing a stable work platform for subsequent inspection work and preventing vehicle shaking from affecting inspection accuracy. The angle adjustment assembly adjusts the angle of the test frame body 3 to adapt to different terrains and sampling directions. The height adjustment assembly drives the mounting plate 4 to slide vertically on the test frame body 3, thereby adjusting the vertical height of the sampling assembly. The horizontal position adjustment assembly drives the mounting platform 5 to slide horizontally on the mounting plate 4, achieving horizontal position adjustment of the sampling assembly. Through adjustment in these three directions, the sampling assembly can be precisely positioned at the foundation location where sampling is required. When the sampling assembly reaches the designated location, the sampling tube 15 is inserted into the foundation. During the sampling process, the shear plate within the sampling tube 15 is subjected to the shearing action of the foundation soil. Data such as the shear force applied to the shear plate can reflect the shear strength characteristics of the foundation soil, and this data is recorded for subsequent analysis. The winding motor 6 is started, driving the winding roller to rotate, thereby controlling the retraction and release of the steel wire. One end of the steel wire passes through the guide support assembly and is connected to the counterweight block. By gradually increasing the number or weight of the counterweight blocks, the steel wire applies a downward pulling force to the foundation, simulating the situation where the foundation bears the load. The guide support assembly plays the role of guiding the direction of the steel wire and bearing the tension of the steel wire, ensuring that the tension can be accurately applied to the foundation. By observing the deformation of the foundation under different tensions (such as settlement, etc.), combined with the magnitude of the applied tension, the bearing capacity of the foundation can be calculated. During the sampling and bearing capacity detection process, the relevant test data will be transmitted to the terminal system in real time, and the terminal system will collect, organize and store these data for subsequent analysis and processing.

[0054] Further optimizing the solution, the angle adjustment component includes:

[0055] Tripod 7, the tripod 7 is provided with two groups, the two groups of tripod 7 are symmetrically fixed to the rear side of the test frame body 3, the tripod 7 is fixed with a mounting shaft, the front side of the engineering vehicle 1 is rotatably connected to a connecting arm 9, one end of the connecting arm 9 is rotatably connected to the mounting shaft;

[0056] An angle-adjusting hydraulic cylinder 8 , one end of which is rotatably connected to the front side of the engineering vehicle 1 , and the other end of which is rotatably connected to the tripod 7 , and an angle is set between the connecting arm 9 and the adjusting hydraulic cylinder.

[0057] The angle adjustment hydraulic cylinder 8 is at its initial length, and the connecting arm 9 maintains a relatively stable connection with the front side of the engineering vehicle 1 and the mounting axis of the tripod 7. At this time, the test stand body 3 is at a default angle position.

[0058] When the angle of the test frame body 3 needs to be adjusted, the angle-adjusting hydraulic cylinder 8 begins to extend and retract. If the hydraulic cylinder extends, it pushes the tripod 7 to rotate about the mounting axis. Since one end of the connecting arm 9 is also rotationally connected to the mounting axis and is rotationally connected to the front side of the engineering vehicle 1, the hydraulic cylinder's thrust causes the tripod 7 to lift the test frame body 3 upward, thereby increasing the angle between the test frame body 3 and the front side of the engineering vehicle 1. Conversely, if the hydraulic cylinder retracts, it pulls the tripod 7 to rotate in the opposite direction about the mounting axis, causing the test frame body 3 to tilt downward and reducing the angle between the test frame body 3 and the front side of the engineering vehicle 1. By precisely controlling the extension and retraction of the angle-adjusting hydraulic cylinder 8, the test frame body 3 can be adjusted to any desired angle to accommodate different terrains and sampling directions.

[0059] Further optimizing the solution, the height adjustment component includes:

[0060] The linear motor 10 is vertically fixed on the test frame body 3 , and the mounting plate 4 is fixed on the slide of the linear motor 10 .

[0061] The linear motor 10 is in an initial position, and the mounting plate 4 is fixed on the slide of the linear motor 10 . At this time, the sampling mechanism is at an initial height.

[0062] When the height of the sampling mechanism needs to be adjusted, linear motor 10 is activated, and its slide moves vertically under the motor's action. If the slide moves upward, it lifts the mounting plate 4, along with the horizontal position adjustment assembly and sampling assembly mounted thereon. If the slide moves downward, it lowers the relevant components. By controlling the operation of linear motor 10, the height of the sampling mechanism can be precisely controlled, ensuring that the sampling assembly reaches the specified depth in the foundation for sampling.

[0063] Further optimizing the solution, the horizontal position adjustment component includes:

[0064] Slide rods 11, wherein two groups of slide rods 11 are provided. The two groups of slide rods 11 are symmetrically and horizontally fixedly connected to the front side of the mounting plate 4, and the mounting platform 5 is slidably connected to the slide rods 11;

[0065] The horizontal position adjusting hydraulic cylinder 12 is arranged between the two groups of the slide bars 11. One end of the horizontal position adjusting hydraulic cylinder 12 is fixed on the mounting plate 4, and the other end is fixed on the back of the mounting platform 5. The horizontal position adjusting hydraulic cylinder 12 is arranged parallel to the slide bars 11.

[0066] The horizontal position adjustment hydraulic cylinder 12 is at an initial length, the mounting platform 5 is at an initial position on the slide bar 11 , and the sampling assembly is at a default horizontal position.

[0067] When the horizontal position of the sampling assembly needs to be adjusted, the horizontal position adjustment hydraulic cylinder 12 begins to extend and retract. If the hydraulic cylinder extends, it will push the mounting platform 5 to slide horizontally along the slide bar 11, moving the sampling assembly to one side; if the hydraulic cylinder contracts, it will pull the mounting platform 5 to slide in the opposite direction along the slide bar 11, moving the sampling assembly to the other side. Since the slide bar 11 is symmetrically fixed horizontally on the mounting plate 4, and the horizontal position adjustment hydraulic cylinder 12 is arranged parallel to the slide bar 11, it can ensure that the mounting platform 5 moves smoothly in the horizontal direction, thereby achieving accurate positioning of the sampling assembly in the horizontal direction and meeting the needs of sampling at different horizontal positions.

[0068] Further optimizing the solution, the sampling assembly includes:

[0069] A mounting seat 13, the mounting seat 13 is fixed on the mounting platform 5;

[0070] A sampling hydraulic cylinder 14 , the sampling hydraulic cylinder 14 is vertically fixed on the mounting base 13 ;

[0071] The sampling tube 15 is fixed to the output end of the sampling hydraulic cylinder 14 through a flange.

[0072] The sampling hydraulic cylinder 14 is in the initial contraction state, and the sampling tube 15 is fixed to the output end of the sampling hydraulic cylinder 14 through a flange. At this time, the sampling tube 15 is located above the sampling position, the shear plate is inserted into the slot of the inlet section of the sampling tube 15, and the pressure sensor is in normal working condition.

[0073] The sampling hydraulic cylinder 14 is started, and its output end extends downward, pushing the sampling tube 15 into the foundation. During the process of inserting the sampling tube 15 into the foundation, the foundation soil enters the sampling tube 15, and the shear plate is sheared by the foundation soil. The pressure sensor detects the shear force exerted on the shear plate in real time and transmits the data to the terminal system. When the sampling reaches the required depth, the sampling hydraulic cylinder 14 stops working, completing the sampling operation. Subsequently, the sampling hydraulic cylinder 14 contracts, driving the sampling tube 15 to be pulled out of the foundation, and the soil sample in the sampling tube 15 can be used for subsequent foundation property analysis.

[0074] Further optimizing the solution, the guide support assembly includes:

[0075] A support frame 16, the support frame 16 is fixed to the top of the test frame body 3;

[0076] A mounting frame 17, the mounting frame 17 being fixed to the top of the support frame 16, and being arranged vertically between the mounting frame 17 and the support frame 16;

[0077] The fixed pulleys 18 are arranged in several groups on the mounting frame 17 , and the steel wire is inserted through several of the fixed pulleys 18 in a serpentine shape.

[0078] One end of the steel wire is fixed to the winding roller, and the other end passes through the fixed pulley 18 on the support frame 16 and the mounting frame 17, and a counterweight is fixed. The steel wire is snake-shaped and passes through several fixed pulleys 18. Through the guiding effect of the fixed pulleys 18, the steel wire can move along a predetermined path.

[0079] The winding motor 6 is started, driving the winding roller to rotate and control the retraction and release of the steel wire. When the winding motor 6 rotates forward, the winding roller reels the steel wire, and the steel wire pulls the counterweight block upward through the fixed pulley 18; when the winding motor 6 rotates reversely, the winding roller unwinds the steel wire, and the counterweight block descends under the action of gravity. During the bearing capacity detection process, by gradually increasing the number or weight of the counterweight blocks, the steel wire applies a downward pulling force to the foundation. The fixed pulley 18 in the guide support assembly can ensure that the pulling force is accurately applied to the foundation, while reducing the friction between the steel wire and the support structure, ensuring the stability and accuracy of the pulling force transmission, thereby realizing the detection of the foundation bearing capacity.

[0080] Further optimizing the solution, the engineering vehicle 1 is equipped with a side lifting assembly, and the side lifting assembly includes:

[0081] A lifting hydraulic cylinder 19, which is fixed to the frame in front of the engineering vehicle 1;

[0082] The lifting frame 20 is fixed on the lifting hydraulic cylinder 19 . The lifting hydraulic cylinder 19 has an arc-shaped groove 21 formed on the lifting frame 20 . The arc-shaped groove 21 is arranged corresponding to the sampling tube 15 .

[0083] The lifting hydraulic cylinder 19 is in an initial contracted state, and the lifting frame 20 is located at a lower position. At this time, the sampling tube 15 has not entered the arc-shaped groove 21 of the lifting frame 20.

[0084] When the sampling tube 15 completes sampling and is pulled upward out of the foundation, the lifting hydraulic cylinder 19 is activated, pushing the lifting frame 20 upward. As the lifting frame 20 rises, the sampling tube 15 gradually enters the arc-shaped groove 21 of the lifting frame 20. The arc-shaped groove 21 can match the shape of the sampling tube 15, providing stable support for the sampling tube 15, preventing the sampling tube 15 from being damaged or affecting the sampling quality due to shaking during the extraction process. When the sampling tube 15 is completely pulled out of the foundation, the lifting hydraulic cylinder 19 maintains a certain pressure to ensure that the sampling tube 15 is stably placed on the lifting frame 20, facilitating the subsequent processing and analysis of the soil sample in the sampling tube 15.

[0085] A further optimized solution is that the shear plate has a cross-shaped structure, and a card slot is provided on the inner wall of the inlet section of the sampling tube 15. There are four groups of card slots, and the four groups of card slots are respectively arranged corresponding to the four edges of the shear plate. The shear plate is inserted into the card slot, and an installation slot is installed in the card slot, and a pressure sensor is installed in the installation slot.

[0086] Insert the four edges of the cross-shaped shear plate into the four sets of slots on the inner wall of the inlet section of the sampling tube 15 to ensure the shear plate is securely installed. Simultaneously, a pressure sensor is installed in the mounting groove within the slots, making close contact with the shear plate to accurately detect the shear force acting on the shear plate.

[0087] Data Collection: During sampling, as the sampling tube 15 is inserted into the foundation, the foundation soil exerts a shearing force on the shear plate. A pressure sensor detects the shear force acting on the shear plate in real time, converts the pressure signal into an electrical signal, and transmits it to the terminal system. The terminal system processes and analyzes the received data to obtain information about the foundation soil's shear strength, providing important information for evaluating the foundation's mechanical properties.
