Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a quality detection device and method for highway construction. Background Art

[0002] The quality inspection of highway construction mainly focuses on the depth of highway structure, the quality of bored piles, fill density and foundation bearing capacity. The foundation bearing capacity inspection method is a key step in evaluating the bearing capacity of the roadbed, which directly affects the safety and stability of the highway. The spiral plate load test method is used to screw the spiral pressure plate into the ground, and the amount of settlement is measured by applying pressure, thereby inspecting the quality of the highway foundation. However, the spiral plate load test method requires the device to be fixed, and it is necessary to drill holes in the foundation again. The fixing method uses threads to enter the foundation for fixing. Screwing the spiral pressure plate below the ground will generate a greater reverse upward force on the device. The surrounding threads enter the foundation in a straight line state. The fixing force is completely dependent on the compaction of the foundation. As a result, the surrounding threads have a weaker fixing force on the device. Under the reverse upward force of the spiral pressure plate, the surrounding fixing threads are easily loosened upward, thus affecting the stability of the test. Summary of the invention

[0003] The present invention provides a quality detection device and method for highway construction, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A quality inspection device and method for highway construction, comprising a controller, a detection mechanism, a fixed plate, and a pull rod structure, wherein the controller is arranged in the middle of the upper end of the fixed plate, and the controller is connected to the internal circuit of the detection mechanism, the fixed plate is arranged in the middle of the upper end of the detection mechanism, and four pull rod structures are rectangularly distributed on the left and right sides of the detection mechanism; The detection mechanism is provided with a pull rod structure, a motor, a base, a drill rod, a stabilizing rod, a bottom plate, and a pusher. Four pushers are provided, which are arranged at the center position of the lower side of the fixed plate and are controlled by the controller to synchronously push the pull rod structure downward so that the pull rod structure slides vertically inside the base. The motor is arranged at the lower end of the pull rod structure. When the pull rod structure slides downward, it drives the drill rod to vertically pass through the bottom plate to generate pressure impact on the foundation. The bottom plate is arranged at the lower end of the base and is horizontally fixed to the foundation surface by the stabilizing rod. The pull rod structure is provided with a spliced ​​rod, a circular joint, and a blocking mechanism. The spliced ​​rod is tilted outward at 50°, and the four spliced ​​rods are symmetrically distributed left and right. The lower end of the spliced ​​rod is bent through the circular joint to allow the blocking mechanism to vertically penetrate into the foundation to fix the base.

[0005] A better technical solution: a circular hole is provided inside the base plate at a position perpendicular to the drill rod. When the pull rod structure is pushed by the pusher, the controller controls the motor to rotate the drill rod, and under the push of the pusher, the drill rod passes through the circular hole in the middle of the base plate and is squeezed into the foundation. A spiral pressure plate is provided on the outer layer of the drill rod. When it rotates into the foundation, the spiral pressure plate generates a squeezing force on the foundation.

[0006] A better technical solution: the circular joint is fitted on the upper end of the blocking mechanism, and the circular joint can rotate in multiple directions with the blocking mechanism as the center point. The circular joint is horizontal to the bottom plate, so that the splicing rod and the foundation surface form a triangular support for the base.

[0007] A better technical solution: the blocking mechanism is provided with a round rod, a push rod, and a blocking plate. The upper end of the push rod moves with the inner thread of the round rod, and the blocking plate is arranged on the outer side of the push rod. The round rod is provided with a hole structure at the position corresponding to the blocking plate. When the push rod drives the blocking plate to move to the hole structure in the round rod, the blocking plate opens outward and squeezes the foundation.

[0008] A better technical solution: the blocking plate is provided with a hinge ring, a bending plate, and a support rod. The bending plates are provided with two, which are divided into upper and lower parts, and the two bending plates are connected and fixed on the hinge ring by the support rod. The hinge ring is arranged inside the push rod, and the middle of the upper bending plate is passed through by the push rod. When the push rod moves downward, the bending plate is driven to squeeze the inner side of the round rod, so that the bending plate elastically presses against the inner wall of the round rod under the support of the support rod.

[0009] A better technical solution: the stabilizing rod is provided with a threaded rod, a nut, and an insertion rod. The threaded rod passes through the base plate, and the outer side of the threaded rod is movable with the nut thread. The insertion rod is arranged at the lower end of the threaded rod, and the outer side of the insertion rod is continuously bent. When the nut rotates, the base plate is squeezed so that it is clamped on the foundation surface by the insertion rod and the nut.

[0010] A better technical solution: the splicing rod is provided with a first connecting rod, a second connecting rod, a threaded tube, and a ball block. The first connecting rod and the threaded tube are threadedly rotated, the ball block is arranged at the lower end of the threaded tube, and the ball block is engaged in the second connecting rod. When the threaded tube rotates, the threaded rotation of the first connecting rod and the threaded tube pushes the second connecting rod connected to the ball block to extend or shorten.

[0011] Quality inspection methods and processes for highway construction: S1: First, the bottom plate at the lower end of the base is placed horizontally on the surface of the highway foundation, and the four round rods are hammered into the foundation by manpower, and the push rod is rotated and screwed into the inside of the round rod to make the blocking plate in a tight elastic pressing state until the bending plate just rotates and moves to the hole structure in the round rod. The bending plate passes through the hole structure under the elastic force to open outward and squeeze into the foundation, so that the blocking mechanism is embedded in the foundation as a whole.

[0012] S2: The thread is screwed into the upper end of the round rod and fixed on the blocking mechanism through the splicing rod connecting the round joint, so that the tie rod structure, the base and the foundation surface form a triangular support.

[0013] S3: At this time, the base plate is fixed on the foundation surface, and the rod is hammered into the foundation through the base plate. By rotating the nut, the nut squeezes the base plate, so that the contact area of ​​the rod in the foundation produces resistance to the left and right movement of the base plate.

[0014] S4: The pusher and the motor are connected to the controller circuit respectively, and the resistance and power pushed by the pusher will be displayed on the controller. From SS, it can be seen that the detection mechanism is fixed as a whole. At this time, the controller controls the pusher to push the pull rod structure, and then the pull rod structure slides vertically in the base. At the same time, the motor is pushed downward by the pull rod structure and rotates the drill rod, so that the drill rod passes through the middle of the bottom plate and squeezes into the foundation. The foundation sinking amount is tested under the pressure of the spiral pressure plate of the drill rod, and the bearing quality of the foundation is measured according to the pressure pushed by the pusher.

[0015] Compared with the prior art, this technical solution has the following advantages: When the bending plate in the present invention elastically presses against the inner wall of the round rod, as the push rod continues to push downward, the bending plate passes through the hole structure corresponding to the round rod and elastically bends outward, and then under the downward force of the push rod, the support rod pushes the bending plate outward and embeds it into the material in the foundation. At this time, the round rod is elastically embedded in the foundation by the blocking plate, and the push rod thread is fixed in the round rod, so the upward force of the push rod by the round rod is shared by the foundation contacted by the bending plate. Therefore, the present invention uses the unique structural grip of the bending plate to the foundation to block the reverse impact received by the base when detecting the foundation quality, thereby ensuring the stability of the detection, preventing the base from vibrating in the opposite direction upward when the drill rod is punched downward, and improving the stability during quality detection.

[0016] After the pull rod structure in the present invention supports the base on all sides, the bottom plate is fixed on the foundation surface by the stabilizing rod, so that after the insertion rod is embedded under the foundation, the threaded rod passes through the bottom plate and is moved by the nut thread, so that when the bottom plate is unstable due to the reverse force, the insertion rod squeezes the contact surface of the foundation left and right. Since the outer side of the insertion rod is bent, the force is relatively uniform and the resistance is large when it moves left and right, ensuring that the bottom plate remains stable through the fixed obstruction of the stabilizing rod, preventing the drill rod from shifting when pushing downward for detection.

[0027] like Figures 1 to 7 As shown, the present invention proposes a quality inspection device and method for highway construction, including a controller 1, a detection mechanism 2, a fixed plate 3, and a pull rod structure 4, wherein the controller 1 is arranged in the middle of the upper end of the fixed plate 3, and the controller 1 is connected to the internal circuit of the detection mechanism 2, the fixed plate 3 is arranged in the middle of the upper end of the detection mechanism 2, and four pull rod structures 4 are rectangularly distributed on the left and right sides of the detection mechanism 2; The detection mechanism 2 is provided with a pull rod structure 4, a motor 22, a base 23, a drill rod 24, a stabilizing rod 25, a bottom plate 26, and a pusher 27. Four pushers 27 are provided, which are arranged at the center position of the lower side of the fixed plate 3 and are controlled by the controller 1 to synchronously push the pull rod structure 4 downward so that the pull rod structure 4 slides vertically inside the base 23. The motor 22 is arranged at the lower end of the pull rod structure 4. When the pull rod structure 4 slides downward, it drives the drill rod 24 to vertically pass through the bottom plate 26 to generate pressure impact on the foundation. The bottom plate 26 is arranged at the lower end of the base 23 and is horizontally fixed to the foundation surface through the stabilizing rod 25. The pull rod structure 4 is provided with a splicing rod 41, a circular joint 42, and a blocking mechanism 43. The splicing rod 41 is tilted outward at 50°, and the four splicing rods 41 are symmetrically distributed on the left and right. The lower end of the splicing rod 41 is bent through the circular joint 42 to allow the blocking mechanism 43 to vertically penetrate into the fixed base 23 inside the foundation, so that the splicing rod 41 and the base 23 are supported in a triangular shape under the fixation of the blocking mechanism 43, thereby fixing the downward push of the pusher 27 to prevent the bottom plate 26 from being separated from the foundation surface and becoming unstable due to the reverse pressure after the bottom plate 26 rotates into the foundation at 254.

[0028] Among them, a circular hole is provided inside the base plate 26 at a position vertically corresponding to the drill rod 24. When the pull rod structure 4 is pushed by the pusher 27, the controller 1 controls the motor 22 to rotate the drill rod 24, and under the push of the pusher 27, the drill rod 24 passes through the circular hole in the middle of the base plate 26 and is squeezed into the foundation. The outer layer of the drill rod 24 is provided with a spiral pressure plate. When it rotates into the foundation, the spiral pressure plate generates a squeezing force on the foundation.

[0029] Among them, the circular joint 42 fits in the upper end of the blocking mechanism 43, and the circular joint 42 rotates in multiple directions with the blocking mechanism 43 as the center point. The circular joint 42 is horizontal to the bottom plate 26, so that the splicing rod 41 and the foundation surface form a triangular support for the base 23, and then the four triangular supports stabilize the base 23 in a rectangular shape to prevent the bottom plate 26 at the lower end of the base 23 from being pushed in the reverse direction.

[0030] Among them, the blocking mechanism 43 is provided with a round rod 431, a push rod 432, and a blocking plate 433. The upper end of the push rod 432 moves with the inner thread of the round rod 431, and the blocking plate 433 is arranged on the outer side of the push rod 432. The round rod 431 is provided with a hole structure at the position corresponding to the blocking plate 433. When the push rod 432 drives the blocking plate 433 to move to the hole structure in the round rod 431, the blocking plate 433 opens outward and squeezes the foundation, so that the blocking plate 433 is embedded in the foundation to increase the upward resistance of the push rod 432, prevent the upper base 23 from driving the splicing rod 41 to pull the blocking mechanism 43, so that the pulling force is shared by the blocking plate 433 to the surrounding foundation, thereby enhancing the stability of the base 23.

[0031] The blocking plate 433 is provided with a hinge ring 4331, a curved plate 4332, and a support rod 4333. The curved plates 4332 are provided with two, one upper and one lower, and the two curved plates 4332 are connected and fixed to the hinge ring 4331 by the support rod 4333. The hinge ring 4331 is arranged inside the push rod 432, and the middle of the upper curved plate 4332 is passed through by the push rod 432. When the push rod 432 moves downward, the curved plate 4332 is driven to squeeze the inner side of the round rod 431, so that the curved plate 4332 is elastically pressed against the inner wall of the round rod 431 under the support of the support rod 4333. Furthermore, each of the curved plates 4332 is equally divided into three arc shapes, and the arc shapes pass through the corresponding hole structures in the round rod 431 .

[0032] Among them, the stabilizing rod 25 is provided with a threaded rod 251, a nut 252, and an insert rod 253. The threaded rod 251 passes through the base plate 26, and the outer side of the threaded rod 251 is threadedly movable with the nut 252. The insert rod 253 is arranged at the lower end of the threaded rod 251, and the outer side of the insert rod 253 is continuously bent. When the nut 252 rotates, the base plate 26 is squeezed so that it is clamped on the foundation surface by the insert rod 253 and the nut 252. The threaded rod 251 passes through the base plate 26, and the outer side of the threaded rod 251 is threadedly movable with the nut 252. There are three threaded rods 251 distributed in a circular array with the drill rod 24 as the center.

[0033] Among them, the splicing rod 41 is provided with a first connecting rod 411, a second connecting rod 412, a threaded tube 413, and a ball block 414. The first connecting rod 411 and the threaded tube 413 are threadedly rotated, and the ball block 414 is arranged at the lower end of the threaded tube 413, and the ball block 414 is engaged in the second connecting rod 412. When the threaded tube 413 rotates, the threaded rotation of the first connecting rod 411 and the threaded tube 413 pushes the second connecting rod 412 connected to the ball block 414 to extend or shorten, thereby adjusting the tightness between the first connecting rod 411 and the blocking mechanism 43 to ensure that the splicing rod 41 to the blocking mechanism 43 is in a tight state. In the tight state, the bottom plate 26 at the lower end of the base 23 is pulled downward by the splicing rod 41 to press against the foundation surface.

[0034] When the curved plate 4332 in the present invention elastically presses against the inner wall of the round rod 431, as the push rod 432 continues to push downward, the curved plate 4332 passes through the hole-shaped structure corresponding to the round rod 431 and elastically bends outward, and then under the downward force of the push rod 432, the support rod 4333 pushes the curved plate 4332 outward and embeds it into the material in the foundation. At this time, the round rod 431 is elastically embedded in the foundation of the blocking plate 433, and the push rod 432 is threadedly fixed in the round rod 431, so that the upward force of the push rod 432 by the round rod 431 is shared by the foundation contacted by the curved plate 4332, and the threads of the first connecting rod 411 and the threaded tube 413 rotate to push the second connecting rod 412 connected to the ball block 414 to extend or shorten, thereby adjusting the tightness between the first connecting rod 411 and the blocking mechanism 43, ensuring that the splicing rod 41 to the blocking mechanism 43 is in a taut state. In the taut state, the bottom plate 26 at the lower end of the base 23 is pulled downward by the splicing rod 41 to press against the foundation surface, so that the reverse force exerted on the bottom plate 26 and the base 23 is shared by the bent plate 4332 into the foundation, so that the blocking mechanism 43 as a whole blocks the upward pulling force of the splicing rod 41. When it needs to be dismantled, the push rod 432 is manually rotated downward to make the bent plate 4332 disengage from the hole structure and press against the inner wall of the round rod 431. At this time, the grip of the round rod 431 on the foundation is weak and the resistance of the round rod 431 in the foundation is small, so the push rod 432 is pulled out to loosen it. Therefore, the present invention uses the unique structural grip of the bent plate 4332 to the foundation, so that the reverse impact exerted on the base 23 when detecting the foundation quality is blocked, thereby ensuring the stability of the detection, preventing the base 23 from vibrating upward in the reverse direction when the drill rod 24 is punched downward, and improving the stability during the detection of quality.

[0035] After the pull rod structure 4 in the present invention supports the base 23 on all sides, the bottom plate 26 is fixed on the foundation surface by the stabilizing rod 25, so that the threaded rod 251 passes through the bottom plate 26 and is threaded by the nut 252 after the insertion rod 253 is embedded under the foundation, and then the nut 252 is rotated so that the bottom plate 26 is clamped on the foundation surface by the nut 252. At this time, the insertion rod 253 generates an upward force on the inside of the foundation, and the resistance is increased by increasing the contact area with the inside of the foundation through the bending structure on the outside of the insertion rod 253. When the bottom plate 26 is unstable due to the reverse force, the insertion rod 253 squeezes the contact surface of the foundation left and right. Since the outer side of the insertion rod 253 is bent, the force is more uniform and the resistance is larger when it moves left and right, ensuring that the bottom plate 26 remains stable through the fixed obstruction of the stabilizing rod 25, preventing the displacement of the drill rod 24 when it is pushed downward for detection.

[0036] Quality inspection methods and processes for highway construction: S1: First, the bottom plate 26 at the lower end of the base 23 is placed horizontally on the surface of the highway foundation, and the four round rods 431 are hammered into the foundation by manpower, and the push rod 432 is rotated and screwed into the inside of the round rod 431, so that the blocking plate 433 is in a tight elastic pressure state, until the bending plate 4332 just rotates and moves to the hole structure in the round rod 431, the bending plate 4332 passes through the hole structure under the elastic force to open outward and squeeze into the foundation, so that the blocking mechanism 43 is embedded in the foundation as a whole, and the blocking mechanism 43 supports the inclined surface of the splicing rod 41. When the base 23 is subjected to an upward reverse force, the blocking mechanism 43 blocks the upward reverse force through the splicing rod 41 to ensure that the base 23 is in a horizontal and stable state.

[0037] S2: The thread is screwed into the upper end of the round rod 431, and the circular joint 42 is connected to the blocking mechanism 43 through the splicing rod 41, so that the tie rod structure 4 and the base 23 and the foundation surface form a triangular support. The triangular support composed of four tie rod structures 4 has a strong stability for the base 23.

[0038] S3: At this time, the base plate 26 is fixed on the surface of the foundation, and the rod 253 is hammered into the foundation through the base plate 26. By rotating the nut 252, the nut 252 squeezes the base plate 26, so that the contact area of ​​the rod 253 in the foundation creates resistance to the left and right movement of the base plate 26. When the base plate 26 shakes left and right, the rod 253 squeezes the foundation left and right, and the stability of the rod 253 on the base plate 26 is increased under the obstruction of its bent surface.

[0039] S4: The pusher 27 and the motor 22 are respectively connected to the controller 1 line, and the resistance and power pushed by the pusher 27 will be displayed on the controller 1. From S1-S3, it can be seen that the detection mechanism 2 is fixed as a whole. At this time, the pusher 27 is controlled by the controller 1 to push the pull rod structure 4, and then the pull rod structure 4 slides vertically in the base 23. At the same time, the motor 22 is pushed downward by the pull rod structure 4 and rotates the drill rod 24, so that the drill rod 24 passes through the middle of the bottom plate 26 and is squeezed into the foundation. The foundation sinking amount is tested under the pressure of the spiral pressure plate of the drill rod 24, and the bearing quality of the foundation is measured according to the pressure pushed by the pusher 27.

[0040] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.

A road construction quality inspection device and method according to claim 1, characterized in that: The splicing rod (41) is provided with a first connecting rod (411), a second connecting rod (412), a threaded tube (413), and a ball block (414); the first connecting rod (411) and the threaded tube (413) are threadedly rotated; the ball block (414) is arranged at the lower end of the threaded tube (413), and the ball block (414) is engaged in the second connecting rod (412); when the threaded tube (413) rotates, the threads of the first connecting rod (411) and the threaded tube (413) rotate to push the second connecting rod (412) connected to the ball block (414) to extend or shorten; Quality inspection methods and processes for highway construction: S1: First, the bottom plate (26) at the lower end of the base (23) is placed horizontally on the surface of the road foundation, and the four round rods (431) are hammered into the foundation by manpower, and the push rod (432) is rotated and screwed into the inside of the round rod (431), so that the blocking plate (433) is in a tight elastic pressing state, until the bending plate (4332) is just rotated and moved to the hole structure in the round rod (431), and the bending plate (4332) passes through the hole structure under the elastic force to open outward and squeeze into the foundation, so that the blocking mechanism (43) is embedded in the foundation as a whole; S2: screwing a thread into the upper end of the round rod (431), connecting the round joint (42) through the splicing rod (41) and fixing it on the blocking mechanism (43), so that the pull rod structure (4) and the base (23) form a triangular support with the foundation surface; S3: At this time, the bottom plate (26) is fixed on the surface of the foundation, and the insertion rod (253) is hammered into the foundation through the bottom plate (26). By rotating the nut (252), the nut (252) squeezes the bottom plate (26), so that the contact area of ​​the insertion rod (253) in the foundation generates resistance to the left and right movement of the bottom plate (26); S4: The pusher (27) and the motor (22) are respectively connected to the controller (1) circuit, and the resistance and power pushed by the pusher (27) are displayed on the controller (1). From S1-S3, it can be seen that the detection mechanism (2) is fixed as a whole. At this time, the controller (1) controls the pusher (27) to push the pull rod structure (4), and then the pull rod structure (4) slides vertically in the base (23). At the same time, the motor (22) is pushed downward by the pull rod structure (4) and rotates the drill rod (24), so that the drill rod (24) passes through the middle of the bottom plate (26) and is squeezed into the foundation.
