Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal and highway technology, specifically a rapid detection device for loose paving thickness in road construction. Background Technology
[0002] Based on past construction experience, the loose-lay thickness of traditional road construction paving materials is often controlled by on-site quality inspectors who rely on their construction experience or use auxiliary tools such as iron bars, long screwdrivers, and measuring tapes to test the loose-lay thickness of the filler. However, the accuracy of the test is not high, the measuring rods are prone to skew, and the measured values have large deviations. This often leads to problems such as material waste, poor construction quality, inadequate control of structural layer elevation, and poor flatness due to inaccurate actual test data. Cost reduction and efficiency improvement are perpetual themes in any engineering project. Cost control and quality control are both extremely important. The quality of cost control directly affects the production and operation of construction companies, while the quality of construction directly impacts the company's reputation and image. In municipal road or highway engineering, the cost of materials accounts for a very high proportion and the quantity used is also very large. As we all know, important roads such as expressways, first-class highways, expressways, and main roads are often characterized by their wide width and long routes, requiring high strength, rigidity, and stability of the structure itself. This necessitates the use of a large amount of high-quality or modified materials or mixtures to pave a layered structure. In addition to paving road materials, there are also many costs associated with the use of large equipment and labor. If the paving thickness is too thin, it will affect the structural strength of the road and reduce its service life. If the paving thickness is too large, it will not be conducive to compaction and will affect the quality. Furthermore, since road projects are very long, ranging from tens of kilometers to hundreds or thousands of kilometers, even a slight deviation in paving thickness will result in a large amount of material waste and increased costs. Severe deviations may even lead to the risk of large-scale rework. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1-3As shown, this utility model provides a technical solution: a rapid detection device for loose paving thickness in road construction, comprising: an insertion rod 8, a ruler 7, and a display screen 6. The insertion rod 8 is inverted L-shaped. The inverted L-shape effectively prevents the user's hand from being injured by the tail end of the insertion rod 8 if the control handle 1 is accidentally damaged when pressed down. In the event of an accident, the user's hand will also be thrown onto the loose paving or the base 4 due to inertia, greatly reducing the risk of injury. The insertion end of the insertion rod 8 is conical, which allows for easier insertion into the loose paving to detect the bottom of the loose paving and thus accurately measure its thickness. The connecting end of the insertion rod 8 is provided with a handle 1, and the surface of the handle 1 is provided with anti-slip threads. To ensure grip stability, the connection point is located at the inverted L end of the insertion rod 8. Compared to the original detection device, this improves safety and prevents the possibility of accidental punctures. The insertion rod 8 and the display screen 6 are connected by a connecting plate 2. The connecting plate 2 is rectangular, which increases the connection area between the insertion rod 8 and the display screen 6, enhancing the stability and service life of the device and preventing accidental damage. The connecting plate 2 ensures that the insertion rod 8 and the display screen 6 move synchronously, allowing the display screen 6 to move synchronously with the insertion rod 8 on the scale 7, so that the detection data can be accurate to the millimeter level. The display screen 6 is equipped with a sliding sleeve on the scale 7, which ensures that the display screen 6 can slide up and down on the scale 7 without detaching from it.
[0022] A base 4 is provided on the connecting end of the scale 7. The base 4 is used to support the entire device on the loose surface to ensure that the device can remain upright when in use. The base 4 and the scale 7 are connected by a fastener 3. The fastener 3 is used to connect the scale 7 to ensure that the scale 7 can be fixed on the base 4. A baffle 5 is provided on the other end of the connecting end of the scale 7. The baffle 5 is located on the top of the scale 7 to prevent the display screen 6 from accidentally detaching from the scale 7 when it moves upward. It is used to prevent the sliding sleeve from detaching from the scale 7.
[0023] A positioning hole is provided on the base 4. The positioning hole is opened through the base 4 and is located at the bottom of the insertion end of the plug rod 8, so as to ensure that the plug rod 8 can pass through the positioning hole and pass through the base 4. The position of the positioning hole corresponds to the position of the plug rod 8.
[0024] like Figure 4 As shown, a method for using a rapid detection device for loose paving thickness in road construction includes the following steps:
[0025] The base 4 is placed on the pine mat. Ensure that the rapid detection device is perpendicular to the pine mat. Set the value of the display screen 6 to zero. Use the handle 1 to drive the insertion rod 8 into the pine mat. When the lower end of the insertion rod 8 reaches the top surface of the lower layer, read the value of the display screen 6, record the value, pull out the insertion rod 8 and put away the device.
[0026] When the insertion rod 8 is inserted into the loose bed, the display screen 6 connected to the insertion rod 8 by the connecting plate 2 moves synchronously with the insertion rod 8 on the scale 7 using a sliding sleeve to ensure accurate reading.
[0027] As described above, this embodiment is a rapid detection device for loose paving thickness in road construction, comprising: a rod 8, which is inverted L-shaped, and a handle 1 is provided on the connecting end of the rod 8. The inverted L-shape of the rod 8 can effectively prevent the user's hand from being injured by the tail end of the rod 8 if the handle 1 is accidentally damaged when the control handle 1 is pressed down. If the inverted L-shape is accidentally damaged, the user's hand will also be hit by the loose paving or the base 4 due to inertia, greatly reducing the risk of injury. The insertion end of the rod 8 is conical, which can be inserted into the loose paving with less effort to detect the bottom of the loose paving, thereby accurately measuring the thickness of the loose paving.
[0028] As described above, this embodiment is a rapid detection device for loose paving thickness in road construction, comprising: a ruler 7 and a display screen 6. An insertion rod 8 and the display screen 6 are connected by a connecting plate 2. The connecting plate 2 is rectangular, which strengthens the connection area between the insertion rod 8 and the display screen 6, enhancing the stability and service life of the device and preventing accidental damage. The connecting plate 2 ensures that the insertion rod 8 and the display screen 6 move synchronously, allowing the display screen 6 to move synchronously with the ruler 7, thus ensuring data accuracy down to the millimeter level. A sliding sleeve is provided behind the display screen 6, mounted on the ruler 7, ensuring that the display screen 6 can slide up and down on the ruler 7 without detaching from it. When the insertion rod 8 is inserted into the bottom of the loose paving and fixed, the display screen 6 reads the value from the ruler 7 and displays it, facilitating real-time image data capture and storage.
[0029] Compared to the original measuring device, the scale 7 may be affected by dirt on site, so the scale 7 needs to be cleaned during use to ensure that there is no jamming or unclear reading. At the same time, the reading is too small, which makes it inconvenient to keep the license plate, and there will be deviation when reading.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
