Description

Technical Field

[0001] This utility model relates to the field of civil engineering equipment technology, and in particular to a rammed earth density testing device. Background Technology

[0002] To test the compaction of the foundation, the density of the rammed earth needs to be tested, usually by water filling or sand filling.

[0003] The prior art discloses a device for testing the density of rammed earth in civil engineering (Publication No.: CN117646462A), which relates to the field of civil engineering equipment. It includes a base, a water-filling cylinder, and a support mechanism. The water-filling cylinder has an inlet and an outlet, with a control valve at the outlet. The base has a central opening, and the outlet of the water-filling cylinder is flexibly connected to the base and communicates with the opening. An annular water storage cavity is formed around the opening within the base, communicating with the opening. The support mechanism includes multiple sets of telescopic rods arranged annularly on the base. The bottom of each telescopic rod is hinged to the base via a hinge assembly, which has a fixed cone. The top of each telescopic rod is fixedly connected to the outer wall of the water-filling cylinder via a first connecting rod, and adjacent telescopic rods are connected via a second connecting rod.

[0004] To reduce the impact of foundation tilt on liquid level readings, existing technologies use movable support rods to keep the liquid storage container vertical. However, the rod structure is relatively complex. In contrast, to ensure the container is vertical, it can be suspended, which guarantees reading accuracy and has a simpler structure.

[0005] Therefore, we propose a device for testing the density of rammed earth. Utility Model Content

[0018] This utility model provides a device for testing the density of rammed earth. It has the following beneficial effects:

[0019] 1. This rammed earth density testing device involves injecting water into a storage tank through a window. The outer wall of the storage tank is marked to record the initial volume of the liquid. A plug is placed at the opening of the drill hole, and a ground nail is driven into the soil. The opening of the drill hole is sealed using a skirt. Water from the storage tank flows into the drill hole through a hose and a hole in the center of the plug. Once the liquid level stabilizes, the volume of the remaining liquid in the storage tank is recorded. The difference between the two liquid volumes is the volume of the cylinder. Because the storage tank is suspended from the bottom of the top plate, it can always remain vertical, thus reducing the interference of uneven or tilted foundations on the liquid level reading and ensuring the accuracy of the liquid level reading.

[0027] A rammed earth density testing device, such as Figure 1 As shown, it includes:

[0028] The top plate 10 has a storage tank 11 for holding liquid suspended at its bottom;

[0029] The stopper assembly includes a stopper body 12, a skirt 13, and a ground stake 14. The stopper body 12 is connected to the storage tank 11 via a hose. The skirt 13 is fixedly connected to the stopper body 12, and the ground stake 14 is slidably connected to the skirt 13. The storage tank 11 forms a sealed tank structure. A window for water injection is provided at the top of the top plate 10. The hose is fixedly installed at the bottom of the storage tank 11. A cable is fixedly connected to the top of the top plate 10 and to the bottom of the top plate 10. The stopper body 12 forms a rubber cylinder. The structure includes a skirt 13 integrally formed on the circumferential surface of the plug body 12, with the skirt 13 flush with the bottom of the plug body 12. The top of the skirt 13 has several circular holes arranged in a ring array, with a ground nail 14 installed in each hole. The ground nail 14 is slidably connected to the corresponding hole. In this design, it is necessary to first drill holes in the foundation using equipment, then weigh the drilled column using a balance, and calculate the compacted foundation by injecting water into the drilled hole or by measuring the volume of the column using the density formula. To determine the density, this method measures the volume of the cylinder by measuring the volume of the borehole. Water is injected into the storage tank 11 through a window. The outer wall of the storage tank 11 has graduations, which record the initial volume of the liquid. The plug 12 is placed at the opening of the borehole, and the ground nail 14 is driven into the soil. The opening of the borehole is sealed using the skirt 13. The hose is clamped with a clamp, which can be removed when water needs to be injected. Water from the storage tank 11 flows into the borehole through the hose and the hole in the center of the plug 12. When the liquid level stabilizes, the volume of the remaining liquid in the storage tank 11 is recorded. The difference between the two liquid volumes is the volume of the cylinder. Since the storage tank 11 is suspended from the bottom of the top plate 10, the storage tank 11 can always remain vertical, thereby reducing the interference of uneven and tilted foundations on the liquid level reading of the storage tank 11, ensuring the accuracy of the liquid level reading, and making the detection convenient and easy to use. The design of the skirt 13 being flush with the plug 12 allows the plug 12 to remain flush with the borehole opening, making it simple and flexible to seal the borehole.

[0030] A support assembly is provided at the bottom of the top plate 10 to support the top plate 10 and adjust the level of the top plate 10.

[0031] The support assembly includes a first support body 20, an adjusting screw 21, a fixing block 22, and a side baffle 23. The fixing block 22 is fixedly connected to the top plate 10, and the side baffle 23 is fixedly connected to the fixing block 22. The first support body 20 is rotatably connected to the fixing block 22. The adjusting screw 21 is threadedly connected to the first support body 20. The fixing block 22 forms a block structure and is fixedly installed at the bottom of the top plate 10. A rotating groove is provided on the bottom surface of the fixing block 22. An integrally formed protrusion is provided on the top of the first support body 20. The protrusion is located in the rotating connection groove. A shaft hole is provided through the fixing block 22 and the protrusion. A rotating shaft is provided in the shaft hole and is fixedly connected to the protrusion. The side baffle 23 forms a rectangular plate structure and is fixedly installed on the side wall of the fixing block 22 and extends inclined towards one side of the fixing block 22. The protrusion can abut against the side baffle 23 to limit the rotation angle of the first support body 20. The first support body 20 forms a hollow cylindrical structure. The first support body 20 has internal threads, and the adjusting screw 21 is threadedly connected to the inner wall of the first support body 20. As a supplementary explanation of the above scheme, by rotating the first support body 20, the protrusion of the first support body 20 rotates in the rectangular groove of the fixing block 22. When the first support body 20 is flipped to the tilted state, the protrusion abuts against the lateral baffle 23, and thus the first support body 20 maintains the tilted state, thereby supporting the top plate 10. At least three sets of support components are provided at the bottom of the top plate 10. By rotating the adjusting screw 21, the bottom of the adjusting screw 21 forms a tip, and thus the adjusting screw 21 can abut against the ground to form support. The three sets of support components work together to adjust the level of the top plate 10 and support the top plate 10, which has good support for the top plate 10 and adaptability to the concavity and convexity of the bottom surface. The flip-out first support body 20 is easy to store and unfold for use.

[0032] The working principle of this utility model is as follows: When the first support body 20 is rotated, the protrusion of the first support body 20 rotates in the rectangular groove of the fixed block 22. When the first support body 20 is flipped to the tilted state, the protrusion abuts against the lateral baffle 23, and the first support body 20 maintains the tilted state to support the top plate 10. At least three sets of support components are provided at the bottom of the top plate 10. When the adjusting screw 21 is rotated, the bottom of the adjusting screw 21 forms a tip, and the adjusting screw 21 can abut against the ground to form support. The three sets of support components work together to adjust the level of the top plate 10 and support the top plate 10.

[0033] Water is injected into the storage tank 11 through a window. The outer wall of the storage tank 11 is marked to record the initial volume of the liquid. The plug 12 is placed at the opening of the drill hole, and the ground nail 14 is driven into the soil. The opening of the drill hole is sealed by the skirt 13. The hose is clamped by a clamp. The clamp can be removed when water needs to be injected. The water in the storage tank 11 flows into the drill hole through the hose and the hole in the center of the plug 12. When the liquid level is stable, the volume of the remaining liquid in the storage tank 11 is recorded. The difference between the two liquid volumes is the volume of the column. Since the storage tank 11 is suspended from the bottom of the top plate 10, the storage tank 11 can always remain vertical, thereby reducing the interference of uneven and tilted foundation on the liquid level reading of the storage tank 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
