Description

Technical Field

[0001] This invention relates to the field of road construction inspection technology, specifically a road construction quality inspection device. Background Technology

[0002] In the field of road construction quality inspection, traditional methods often rely on manual sampling or single-function equipment. Manual inspection is not only inefficient, but the results are also heavily influenced by the operator's subjective factors, making it difficult to guarantee accuracy and consistency. Existing testing equipment often faces numerous problems when dealing with the need for multiple sampling inspections of a construction area. Frequent and close sampling within a single area generates a large number of sampling holes, which can cause soil deformation. This soil deformation negatively impacts subsequent foundation construction quality, such as reducing the soil's bearing capacity and affecting the stability of the road base, potentially leading to road settlement, cracking, and other quality issues. Furthermore, some devices designed to repair soil at sampling locations simply employ traditional compaction during the repair process. However, road construction soil is generally hard and lumpy, and traditional compaction cannot effectively bond the repaired area, affecting construction quality. Devices using water spraying functions can wet and damage large areas of soil during spraying, affecting the hardness and quality of the soil, increasing later road maintenance costs, and even threatening road safety. Furthermore, traditional testing equipment cannot guarantee the integrity of soil samples during the sampling process. Samples are easily detached or damaged due to external forces during extraction, leading to deviations in the test data and failing to accurately reflect the true quality of road construction.

[0003] Therefore, in order to solve the problem, a road construction quality inspection device is proposed that can reduce damage to soil structure while ensuring the accuracy of the test, and has the characteristics of automation and multi-functionality. Summary of the Invention

[0004] The purpose of this invention is to provide a road construction quality testing device that solves the problem of soil deformation caused by frequent sampling in existing road construction quality testing, which affects the quality of foundation construction. The device can accurately detect the quality of road construction while effectively restoring the sampled soil area. In particular, the newly added adhesive function improves the adhesion effect after soil restoration, further ensuring the quality of construction.

Drainage holes are evenly opened on the side of the collecting cylinder, and the drainage holes communicate with the cavity. Several wetting holes are evenly opened on the side of the collecting cylinder, and the wetting holes communicate with the cavity.

[0011] Furthermore, grooves are provided above the cutting cylinder and below the connecting cover, and several balls are evenly arranged in the grooves;

[0012] A cutting gear is fixedly installed on the inner side of the upper part of the cutting cylinder.

[0013] Furthermore, the inner wall of the water-blocking tank is symmetrically provided with reset damping rods, and a tamping plate that is movably adapted to the inner wall of the collection cylinder is fixed below the reset damping rods. A tamping rod is fixed above the tamping plate. A detection motor is fixedly provided on the inner wall of the connecting cover, and a detection gear is adapted to the output end of the detection motor.

[0014] The detection gear meshes with the cutting gear;

[0015] A detection rod is fixedly installed inside the collection cylinder, and a temperature and humidity detector is installed inside the detection rod.

[0016] The surface of the tamping plate is equipped with a detection scraper, which is dynamically adapted to the surface of the detection rod.

[0017] Furthermore, symmetrical holes are provided on the lower part of the body.

[0018] Furthermore, the rotating device includes a rotating motor fixedly installed on the upper part of the inner wall of the machine body, and the output end of the rotating motor is adapted to have a rotating shaft.

[0019] Furthermore, the lifting device includes a lifting slide rail fixedly installed below the rotating shaft.

A lifting slide plate is fixedly installed at one end of the lifting damping rod, and a lifting ring is fixedly installed on one side of the lifting slide plate.

[0020] Furthermore, the pressure device includes a pressure rod fixedly installed on the upper part of the inner wall of the machine body, and a conical plate fixedly installed below the pressure rod.

[0021] Furthermore, the bonding device includes a water tank fixedly installed above the machine body and a water pump fixedly installed above the inner wall of the machine body. The water pump and the water tank are connected and communicate with each other through water pipes. A wetting pipe is fixedly installed below the water pump, and the wetting pipe faces the water-blocking tank.

[0022] The beneficial effects of this technical solution are:

[0023] (1) Through the unique design of the detection device, the present invention can ensure the integrity of the soil sample during the sampling process, avoid soil falling off due to rotation, and improve the accuracy of the detection results. The temperature and humidity detector built into the detection rod can monitor the soil temperature and humidity data in real time, providing a scientific basis for the proportion of road construction materials and the adjustment of construction technology. Compared with traditional detection methods, the detection data is more comprehensive and accurate.

[0024] (2) The automatic lifting of the detection device is achieved by using pressure device and lifting device, which is convenient and quick to operate and improves the efficiency of detection work. In addition, the device integrates multiple functions, eliminating the need for operators to frequently change equipment or perform complex operation steps, thus greatly saving manpower and time costs.

[0025] (3) The rotating device can switch between the two detection devices. When conducting multiple sampling tests, it reduces repeated damage to the soil in the same area. At the same time, this design also increases the flexibility of the detection device. The working mode of the detection device can be flexibly adjusted according to different detection needs and site conditions to adapt to the complex and ever-changing road construction environment.

[0026] (4) By combining the tamping hammer and the testing device, after a new sampling is completed, the soil sampled last time can be backfilled and tamped in a timely manner, which effectively reduces the impact of the sampling hole on the soil structure, ensures the quality of foundation construction, reduces the cost of road maintenance in the later stage, and improves the overall quality and safety of road construction. In addition, the testing scraper cleans the surface of the testing rod during the tamping process, which can prevent soil residue from affecting the normal operation and testing accuracy of the testing rod, extend the service life of the testing device, and reduce the frequency and cost of equipment maintenance.

[0027] (5) The cavity between the cutting tube and the collecting tube increases air circulation and improves cooling efficiency, which helps protect the testing device and soil sample. When conducting testing in a high-temperature environment, this design can effectively avoid performance degradation and failure caused by overheating of the equipment, ensuring the continuity and stability of the testing work. At the same time, it can better preserve the original characteristics of the soil sample and ensure the reliability of the test data.

[0028] (6) The adhesive device can perform targeted wetting and bonding treatment on the soil before backfilling. Through the precise adhesive delivery path design, only the outside of the soil in the collection tube is wetted, avoiding excessive wetting and damage to large areas of soil. After the soil is treated with adhesive and compacted, the bonding effect with the original ground is significantly improved, effectively solving the problem that traditional compaction cannot effectively bond hard block soil, further enhancing the stability of the soil after repair, and providing a more reliable guarantee for the quality of road construction.

[0046] A water-proof groove 718 is fixedly provided on the inner wall of the connecting cover 701. A water storage trough 719 is provided in the water-proof groove 718 for temporarily storing soil adhesive. Water passage holes 720 are symmetrically opened in the water storage trough 719 to facilitate the flow of adhesive into the water storage cavity of the collection cylinder 703. A partition plate 715 is fixedly provided on the upper part of the inner wall of the collection cylinder 703 by welding.

[0048] A tamping hammer 9 is fixedly installed on the other side of the inner wall of the machine body 1 by welding, which is used to tamp and restore the soil area after sampling; symmetrical holes 101 are opened at the bottom of the machine body 1 to facilitate the descent of the detection device 7 for sampling and soil backfilling.

[0049] An adhesive device 10 is fixedly installed on the inner wall of the machine body 1. The adhesive device 10 includes a water tank 1001 fixedly installed on the upper part of the machine body 1 and a water pump 1002 fixedly installed on the upper part of the inner wall of the machine body 1. The water tank 1001 is used to store soil adhesive. The water pump 1002 is connected to the water tank 1001 through a water pipe. The water pipe adopts a quick-connect interface for easy installation and maintenance. A wetting pipe 1003 is fixed below the water pump 1002 by bolts. The wetting pipe 1003 faces the water-blocking trough 718. The water pump 1002 can draw out the adhesive in the water tank 1001 and spray it out through the wetting pipe 1003. The orientation design of the wetting pipe 1003 allows the sprayed adhesive to fall accurately into the water-blocking trough 718, preparing for subsequent soil wetting and adhesion.

[0050] The specific implementation process is as follows:

[0051] The operator grips the push rod 3 and pushes the device with their own strength. The roller 2 moves across the road construction area using the rolling friction with the ground, transporting the device to the designated testing point. Upon arrival at the testing point, the operator sets parameters on the control panel 4, including testing depth, number of samplings, and compaction strength, and selects to start the testing program. At this point, the device enters the standby state.

[0052] Control panel 4 sends a descent command to pressure rod 801, the motor inside pressure rod 801 starts, driving the lead screw to rotate; the lead screw, through threaded transmission, causes the nut to move downward along the lead screw, thereby pushing pressure rod 801 to extend downward; pressure rod 801 drives tapered plate 802 to descend synchronously, after the tapered surface of tapered plate 802 contacts connecting cover 701, as pressure rod 801 continues to descend, tapered plate 802 applies pressure evenly to connecting cover 701;

[0053] Under pressure, the connecting cover 701, through its bolt connection with the lifting ring 605, drives the cutting cylinder 702 and the collecting cylinder 703 to move downwards; the lifting ring 605 pushes the lifting slide plate 604 to slide within the lifting groove 602 of the lifting slide rail 601, and the lifting slide plate 604 squeezes the lifting damping rod 603 to retract it; during the retraction process, the lifting damping rod 603 uses its internal hydraulic or spring structure to generate damping force, which plays a buffering role, preventing the detection device 7 from descending too quickly, while ensuring the smoothness of the descent process and preventing the device from shaking and affecting the sampling accuracy;

[0054] As the detection device 7 descends, the control panel 4 activates the detection motor 710. Upon powering on, the stator of the detection motor 710 generates a rotating magnetic field, and the rotor begins to rotate under electromagnetic force. The rotor drives the detection gear 711 to rotate via a key connection. The detection gear 711 meshes with the cutting gear 712, transmitting power to the cutting gear 712. The cutting gear 712 is fixed to the inner side of the upper part of the cutting cylinder 702. As the cutting gear 712 rotates, the cutting cylinder 702 begins to rotate around its own axis. Since the cutting cylinder 702 and the collecting cylinder 703 are connected by ball bearings 706 and do not contact each other, the rotation of the cutting cylinder 702 does not cause the collecting cylinder 703 to rotate. During the rotation of the cutting cylinder 702, its sharp blade at the lower end cuts the soil. The cut soil sample enters the collecting cylinder 703. Simultaneously, the cavity 704 between the cutting cylinder 702 and the collecting cylinder 703 promotes air circulation, carrying away the heat generated during the cutting process, reducing the device temperature, and protecting the original properties of the detection device 7 and the soil sample.

[0055] The temperature and humidity detector built into the detection rod 713 inside the collection tube 703 monitors the temperature and humidity data of the soil sample in real time and transmits the data to the control panel 4 for storage and display, providing data support for subsequent road construction quality analysis;

[0056] When the cutting cylinder 702 and the collecting cylinder 703 descend to the predetermined detection depth, and the soil sample in the collecting cylinder 703 is collected, the control panel 4 sends an upward command to the pressure rod 801; the motor inside the pressure rod 801 reverses, the lead screw drives the nut to move upward, causing the pressure rod 801 to contract, and the conical plate 802 rises accordingly, relieving the pressure on the connecting cover 701.

[0057] Under the action of its own elastic restoring force, the lifting damping rod 603 pushes the lifting slide plate 604 to slide upward in the lifting groove 602. The lifting slide plate 604 drives the connecting cover 701, the cutting cylinder 702 and the collecting cylinder 703 to rise through the lifting ring 605 until the detection device 7 returns to the initial position.

[0058] Control panel 4 starts the rotary motor 501. After the rotary motor 501 is powered on, its rotor rotates under the drive of electromagnetic force, which drives the rotary shaft 502 to rotate through the key connection. The rotary shaft 502 drives the lifting slide rail 601 to rotate 180 degrees. The lifting slide rail 601 drives the detection device 7 to rotate through the welded and fixed lifting slide plate 604 and lifting ring 605, rotating the originally non-working detection device 7 to above the hole 101 below the machine body 1, preparing for the next sampling.

[0059] During the process of moving the device from the previous sampling location to the next sampling location, the operator controls the water pump 1002 via the control panel 4. After the water pump 1002 starts, it uses its own suction to extract the soil binder stored in the water tank 1001. The binder can be water or other special binders. It is transported through the water pipe to the wetting pipe 1003 and sprayed out from the wetting pipe 1003. Since the wetting pipe 1003 faces the water-blocking trough 718, the sprayed soil binder collects in the water stored in the water-blocking trough 718. In the tank 719, as the amount of adhesive in the water storage tank 719 increases, the adhesive flows into the water storage cavity in the collection cylinder 703 through the water passages 720 that are symmetrically opened inside. The adhesive in the water storage cavity is then discharged into the cavity 704 through the drain hole 716 on the side of the collection cylinder 703. In the cavity 704, the adhesive comes into contact with the dry soil in the collection cylinder 703 through the wetting hole 717, wetting the outermost layer of the soil and forming a wet layer with adhesive effect on the outermost layer of the soil, thereby enhancing the adhesion between soils.

[0060] Secondary sampling and testing and subsequent procedures:

[0061] The operator pushes the device so that the hole 101 near the push rod 3 at the bottom of the machine body 1 is aligned with the soil hole left by the previous sampling; the control panel 4 restarts the pressure rod 801 and the detection motor 710, repeating the above operation process of the detection device 7 descending and sampling, to collect a new soil sample.

[0062] While new samples are being collected, the control panel 4 activates the tamping hammer 9; the tamping hammer 9 begins to descend slowly with a small downward amplitude. When the lower end of the tamping hammer 9 contacts the tamping rod 707, as the tamping hammer 9 continues to descend, its impact force is transmitted to the tamping plate 709 through the tamping rod 707; the tamping plate 709 moves downward in the collection cylinder 703, pushing out the soil sample collected in the collection cylinder 703 and filling the soil hole left by the previous sampling.

[0063] The tamping hammer 9 continues to repeatedly strike the tamping rod 707 with a gradually increasing downward amplitude, causing the tamping plate 709 to compact the backfilled soil. During the compaction process, the soil surface is moistened by the adhesive, resulting in better adhesion. This allows the sampled dry soil to better bond with the original ground surface. Simultaneously, the detection scraper 714 on the surface of the tamping plate 709 contacts the surface of the detection rod 713, scraping away the soil adhering to the surface of the detection rod 713, keeping the surface of the detection rod 713 clean, and ensuring the normal operation and detection accuracy of the temperature and humidity detector. After multiple hammer blows, the backfilled soil is compacted, restoring the soil density and reducing the impact of the sampling hole on the soil structure. Furthermore, the adhesive further ensures the construction quality. By repeating the above operation process of lowering and sampling, raising and repositioning, applying adhesive, and backfilling and compacting the soil, multiple sampling tests can be carried out in the road construction area, and the soil area after each sampling can be effectively restored and bonded with high quality.
