Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and in particular to a composite structure of an driven earth pressure gauge. Background Technology

[0002] In geotechnical engineering testing, earth pressure gauges are often buried inside the support structure or foundation, and their installation method directly affects the accuracy and long-term stability of the measurement data.

[0003] To test the changes in earth pressure at the front and rear rows of a curtain-type wharf, earth pressure gauges are typically installed at different depths along the same axis using pilot-hole installation. This method involves using large-diameter pilot holes, which disturbs a large area of ​​soil and cannot be restored quickly, significantly impacting the test results. Furthermore, verticality is difficult to control. In addition, accurately installing earth pressure gauges at different depths at the same location is challenging. If the guide device has too low rigidity, it is prone to bending during installation; if the rigidity is too high, it cannot be installed correctly. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an insertion type earth pressure gauge assembly structure to solve various problems existing in the prior art of using borehole installation of earth pressure gauges.

[0005] To achieve the above and other related objectives, this utility model provides an integrated structure for an inserted earth pressure gauge, comprising a first U-shaped channel steel, the first U-shaped channel steel including a first web plate, a first side plate and a second side plate respectively provided on both sides of the first web plate, a wire hole provided on the first web plate, an earth pressure sensor fixedly mounted on the front side of the first web plate, and a cable of the earth pressure sensor passing through the wire hole to the rear side of the first web plate; a first protective cover, the first protective cover being fixedly mounted on the front side of the first web plate, with the wire hole located below the first protective cover, forming a first protective channel between the first protective cover and the front side of the first web plate; and a second protective cover, the second protective cover being fixedly mounted on the rear side of the first web plate, forming a second protective channel between the second protective cover and the rear side of the first web plate.

[0006] Furthermore, a soil-retaining ring is fixedly provided on the first web plate, and the soil-retaining ring is arranged around the soil pressure sensor.

[0007] Furthermore, the first protective channel is filled with silicone, and both ends of the first protective channel are equipped with sealing baffles.

[0008] Furthermore, the first protection channel is provided with an upwardly extending bulldozer blade at one end near the earth pressure sensor.

[0009] Furthermore, it also includes a second U-shaped channel steel, which includes a second web plate, and a third side plate and a fourth side plate are respectively provided on both sides of the second web plate, wherein the third side plate is welded and fixed to the first side plate, and the fourth side plate is welded and fixed to the second side plate.

[0010] Furthermore, an I-beam is welded and fixed to the side of the second web away from the first U-shaped channel steel.

[0011] Furthermore, the earth pressure sensor is fixedly mounted on the front side of the first web plate by screws.

[0012] As described above, the driven earth pressure gauge assembly structure of this utility model has the following beneficial effects: In use, the driven earth pressure gauge assembly structure can be driven into the soil to be measured using a piling device. Furthermore, multiple driven earth pressure gauge assemblies of this utility model can be spliced ​​together according to the needs of testing soil at different depths, that is, by welding the first U-shaped channel steel of two driven earth pressure gauge assemblies together. Compared with the pre-drilled installation method in the prior art, although the driven earth pressure gauge assembly structure of this utility model also causes compression and disturbance to the soil, the soil remains essentially in its original state. The disturbance caused by pre-drilling is significantly reduced, thus ensuring that the soil pressure measured by the earth pressure sensor is as close as possible to the actual soil pressure, thereby greatly improving the measurement accuracy and ensuring the accuracy of the measurement structure.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Please see Figures 1 to 3 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] This utility model provides a combined structure for an driven earth pressure gauge, such as... Figures 1 to 3 As shown, the driven earth pressure gauge assembly structure includes a first U-shaped channel steel 10, which includes a first web 11. The first web 11 has a first side plate 12 and a second side plate 13 on both sides. Specifically, a wire hole 110 is provided on the first web 11. An earth pressure sensor 100 is fixedly mounted on the front side of the first web 11, and the cable of the earth pressure sensor 100 is passed through the wire hole 110 to the rear side of the first web 11. A first protective cover 20 is fixedly mounted on the front side of the first web 11, and the wire hole... 110 is located below the first protective cover 20. The first protective cover 20 and the front side of the first web 11 form a first protective channel 201. The first protective channel 201 is used to protect the cable of the earth pressure sensor located on the front side of the first web 11. A second protective cover 30 is fixedly provided on the rear side of the first web 11. The second protective cover 30 and the rear side of the first web 11 form a second protective channel 301. The second protective channel 301 is used to protect the cable of the earth pressure sensor that passes through the wire hole 110 to the rear side of the first web 11.

[0039] The beneficial effects of this utility model's driven earth pressure gauge assembly structure are as follows: In use, the assembly structure can be driven into the soil to be measured using a piling device. Furthermore, multiple driven earth pressure gauge assemblies can be spliced ​​together according to the needs of testing soil at different depths, specifically by welding the first U-shaped channel steel of two driven earth pressure gauge assemblies together. Compared to the pre-drilled installation method in the prior art, although this utility model's driven earth pressure gauge assembly structure also causes compression and disturbance to the soil, the soil remains essentially in its original state. This significantly reduces the disturbance compared to pre-drilled installation, thus ensuring that the earth pressure measured by the earth pressure sensor is as close as possible to the actual earth pressure, thereby greatly improving measurement accuracy and ensuring the precision of the measurement structure.

[0040] Furthermore, to ensure that when the earth pressure sensor 100 is driven into the soil, the soil exerts radial pressure on it, thereby affecting the stability of the connection between the earth pressure sensor 100 and the first web 11, preferably, as follows: Figure 2As shown, in this embodiment, a retaining ring 111 is fixedly provided on the first web 11, and the retaining ring 111 is arranged around the earth pressure sensor 100. When the earth pressure sensor is driven into the soil, the retaining ring 111 can protect the earth pressure sensor 100 from radial compression, which greatly improves the stability of the connection of the earth pressure sensor 100 to the first web.

[0041] Specifically, in this embodiment, the earth pressure sensor 100 is fixed to the front side of the first web plate 11 by screws. The structure is simple and easy to assemble and disassemble.

[0042] Furthermore, in order to ensure the stability of the earth pressure sensor cable in the first protection channel 201 and to prevent soil from entering the first protection channel 201 and damaging the cable when it is driven into the soil, preferably, in this embodiment, the first protection channel 201 is filled with silicone, and sealing baffles are provided at both the front and rear ends of the first channel 201.

[0043] Furthermore, to ensure the ease of inserting the earth pressure gauge into the soil, priority should be given to, such as Figure 2 As shown, in this embodiment, a bulldozer plate 21 extending upwards at an angle is provided at one end of the first protective channel 201 near the earth pressure sensor 100. With the bulldozer plate 21 in place, when the earth pressure sensor is driven into the soil, the bulldozer plate 21 is inclined upwards, so it can effectively push the soil to the side, which is beneficial for the downward driving of the first protective cover 20.

[0044] Furthermore, in order to protect the cable in the second protection channel 301, after the pressure sensor cable is passed through the through hole 110 to the rear side of the first web 11, and before the second protective cover 301 is installed, asbestos cloth can be wrapped around the cable, i.e. the cable located on the rear side of the first web 11.

[0045] Specifically, in this embodiment, both the first protective cover 20 and the second protective cover 30 are U-shaped channel steel. Both the first protective cover 20 and the second protective cover 30 are welded to the first U-shaped channel steel, resulting in a simple structure and high strength.

[0046] Furthermore, in order to improve the structural strength of this driven earth pressure gauge assembly, such as... Figure 1 and Figure 3 As shown, in this embodiment, a second U-shaped channel steel 40 is also included. The second U-shaped channel steel 40 includes a second web plate 41. A third side plate 42 and a fourth side plate 43 are respectively provided on both sides of the second web plate 41. The third side plate 42 is welded and fixed to the first side plate 12 of the first U-shaped channel steel, and the fourth side plate 43 is welded and fixed to the second side plate 43 of the first U-shaped channel steel.

[0047] To further improve the structural strength of this driven earth pressure gauge assembly and ensure its stability during driving into the soil, such as... Figure 3 As shown, an I-beam 50 is also welded and fixed on the side of the second web 41 away from the first U-shaped channel steel 10.

[0048] In summary, the driven earth pressure gauge assembly structure of this invention ensures that the earth pressure measured by the earth pressure sensor is close to the actual earth pressure, thereby greatly improving the measurement accuracy and guaranteeing the accuracy of the measurement structure. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
