Description

Technical Field

[0001] This utility model relates to the field of roadbed compaction measurement technology, and more specifically, to a road engineering roadbed compaction measuring device. Background Technology

[0002] Subgrade compaction degree is one of the key indicators for testing the construction quality of subgrade and pavement. It characterizes the density after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. In road construction, ensuring that the subgrade compaction degree meets the design requirements is an important link in ensuring the service life of the road and driving safety. However, existing subgrade compaction degree measuring devices have some problems in use.

[0003] Traditional methods for determining subgrade compaction, such as the ring cutter method, involve pressing a ring cutter into the subgrade, taking a sample, and then transferring the sample to a laboratory to derive the compaction value using relevant formulas. However, the ring cutter sampling tube and device are often fixed in place, making it inconvenient to disassemble and clean the inside of the tube during use. Therefore, we propose an improved subgrade compaction determination device for road engineering. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As described in the background art, traditional methods for determining the compaction degree of roadbeds, such as the ring cutter method, involve pressing the ring cutter into the roadbed, taking a sample, transferring the soil sample to the laboratory, and obtaining the specific value of compaction degree based on relevant formulas. However, the ring cutter sampling tube and device are mostly fixed, making it inconvenient to disassemble the sampling tube during use, and consequently, inconvenient to clean the inside of the sampling tube.

[0028] To solve this technical problem, this utility model provides a device for measuring the compaction degree of roadbed in road engineering.

[0029] For details, please refer to Figures 1-4 The road engineering subgrade compaction degree measuring device specifically includes:

[0030] A support plate 1 has an installation groove 103 on its side. A sampling cylinder body 105 is installed in the installation groove 103. A support seat 104 is sleeved on the outer surface of the sampling cylinder body 105 through a bearing. A side groove 106 is opened on the outer periphery of the support seat 104 and is inserted into the inner wall of the installation groove 103. A stop rod 108 is hinged to one side of the support plate 1 and is inserted into the inner wall of the side groove 106.

[0031] The road engineering subgrade compaction degree measuring device provided by this utility model, through the installation groove 103 and the side groove 106, enables the support base 104 and the support plate 1 to cooperate with each other to support the sampling cylinder body 105, so that the sampling cylinder body 105 can be removed from the support plate 1, thereby facilitating the cleaning of the inside of the sampling cylinder body 105 and making it convenient for testing personnel to use.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1, please refer to Figures 1-4 A roadbed compaction degree measuring device includes a support plate 1, with an installation groove 103 on the side of the support plate 1. A sampling cylinder body 105 is disposed in the installation groove 103. A support seat 104 is sleeved on the outer surface of the sampling cylinder body 105 via a bearing. A side groove 106 is formed on the outer periphery of the support seat 104, and the side groove 106 is inserted into the inner wall of the installation groove 103. A stop rod 108 is hinged to one side of the support plate 1, and the stop rod 108 is inserted into the inner wall of the side groove 106. The device uses the insertion of the installation groove 103 and the side groove 106 to enable the support seat 104 and the support plate 1 to cooperate in supporting the sampling cylinder body 105, allowing the sampling cylinder body 105 to be removed from the support plate 1, thus facilitating cleaning inside the sampling cylinder body 105 and making it convenient for testing personnel to use.

[0036] Furthermore, such as Figures 1-2 As shown, a hand-tightening bolt 109 is provided on the stop rod 108, and a fixing seat 110 is fixedly installed on the side of the support plate 1. The fixing seat 110 is provided with a threaded hole, and one end of the hand-tightening bolt 109 is connected to the threaded hole. The position of the stop rod 108 can be fixed by the cooperation of the threaded hole, the fixing seat 110 and the hand-tightening bolt 109, so that the stop rod 108 limits the support seat 104. After rotating the hand-tightening bolt 109 to separate the hand-tightening bolt 109 from the threaded hole, rotating the stop rod 108 to separate the stop rod 108 from the side groove 106 can release the limitation on the support seat 104.

[0037] Furthermore, such as Figure 1As shown, a motor 101 is installed on the top of the support plate 1. The output shaft of the motor 101 is connected to a drive gear 102. The drive gear 102 meshes with a driven gear 107, and the driven gear 107 is fixedly sleeved on the outer surface of the sampling cylinder body 105. The motor 101 can drive the sampling cylinder body 105 to rotate through the mutual cooperation of the drive gear 102 and the driven gear 107, so that the blade at the bottom of the sampling cylinder body 105 can perform a ring cutting operation.

[0038] Example 2 further optimizes the road engineering subgrade compaction degree measuring device provided in Example 1, specifically, as follows: Figure 1 and Figure 3 As shown, a push plate 2 is slidably disposed inside the sampling tube body 105. A push rod 201 is fixedly connected to the top of the push plate 2. The top end of the push rod 201 protrudes from the top of the sampling tube body 105. After sampling is completed, the push rod 201 can be pushed to push the soil sample out of the sampling tube body 105 through the push plate 2, thereby facilitating the removal of the soil sample. The push plate 2 and the push rod 201 can be removed from the sampling tube body 105 for easy cleaning.

[0039] Furthermore, a base 3 is provided below the support plate 1, and a lifting component is provided between the base 3 and the support plate 1. The lifting component can drive the support plate 1 to rise and fall, thereby realizing the rising and falling of the sampling cylinder body 105.

[0040] Furthermore, such as Figure 1 As shown, the lifting component includes a hydraulic cylinder 301 mounted on the top of the support plate 1. The piston rod of the hydraulic cylinder 301 passes through the support plate 1 and is connected to the base 3. The hydraulic cylinder 301 can drive the support plate 1 to rise and fall.

[0041] Furthermore, such as Figure 1 As shown, limit rods 302 are fixedly connected to both sides of the top of the base 3. The top ends of the two limit rods 302 pass through the support plate 1. The limit rods 302 can limit the support plate 1, thereby improving the stability of the support plate 1 when it is raised or lowered.

[0042] Furthermore, such as Figure 2 As shown, a through-hole 303 is provided on the base 3. The position of the through-hole 303 corresponds to the position of the sampling tube body 105. The through-hole 303 is used to avoid the sampling tube body 105.

[0043] Example 3 further optimizes the road engineering subgrade compaction degree measuring device provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, a protective sleeve 4 is inserted into the inner wall of the port 303. The protective sleeve 4 is inserted into the bottom opening of the sampling tube body 105. Before use, the protective sleeve 4 protects the blade at the bottom of the sampling tube body 105, which can reduce the possibility of damage to the blade.

[0044] Furthermore, such as Figure 1 As shown, the base 3 is provided with several fixing bolts 305, which can fix the base 3 to the roadbed to improve the overall stability during use.

[0045] The usage process of the road engineering subgrade compaction degree measuring device provided by this utility model is as follows:

[0046] Place the base 3 in the sampling area, rotate the fixing bolt 305 so that the fixing bolt 305 is screwed into the roadbed, the hydraulic cylinder 301 drives the support plate 1 to rise, and remove the protective sleeve 4 from the opening 303. Then the hydraulic cylinder 301 drives the support plate 1 to fall. During the fall of the support plate 1, the motor 101 drives the driven gear 107 to rotate through the drive gear 102, and then drives the sampling cylinder body 105 to rotate, so that the sampling cylinder body 105 is screwed into the roadbed for sampling. After the sampling is completed, the hydraulic cylinder 301 drives the support plate 1 to rise, rotate the hand-tightening bolt 109 so that the hand-tightening bolt 109 is separated from the threaded hole, rotate the stop rod 108 so that the stop rod 108 is separated from the side groove 106, push the support seat 104 to remove the support seat 104 and the sampling cylinder body 105, push the push rod 201, and the push rod 201 drives the push plate 2 to push out the soil sample in the sampling cylinder body 105. The soil sample can then be transferred to the laboratory for testing.

[0047] During installation, insert the side groove 106 into the mounting groove 103, and make the driven gear 107 correspond to and mesh with the driving gear 102. Rotate the stop bar 108 to insert the stop bar 108 into the side groove 106. Tighten the hand-tightening bolt 109 into the threaded hole. Place the protective sleeve 4 into the through port 303. The hydraulic cylinder 301 drives the support plate 1 to descend so that the bottom of the sampling cylinder body 105 is inserted into the protective sleeve 4.
