Description

Technical Field

[0001] This utility model belongs to the technical field of soil testing devices, specifically relating to a device for measuring the thickness of backfill soil. Background Technology

[0002] For bare rock areas, long-term exposure to the external environment and exposure to wind and sun can easily lead to sandification, resulting in soil erosion and environmental damage. To avoid this, the existing conventional technical means is to cover the bare rock with a layer of soil and restore greenery by planting vegetation. This avoids the exposure of the bare rock and can also accelerate the restoration of the ecological environment. In order to ensure the stability of the vegetation, the thickness of the backfill soil layer needs to be tested.

[0003] In the relevant prior art, such as Chinese Patent No. CN222617798U, a soil thickness detection device is disclosed. The soil thickness detection device includes a protective sleeve and an insertion mechanism. The insertion mechanism is disposed on the protective sleeve. It also includes a stabilizing mechanism, which includes a stabilizing block, a supporting piercing block, a supporting block, and a connecting mechanism. The supporting piercing block is disposed on the stabilizing block and the stabilizing block abuts against the soil. The supporting block is disposed on the stabilizing block, and the protective sleeve is connected to the supporting block through the connecting mechanism.

[0004] However, in actual use, the protective sleeve restricts the downward movement of the insertion mechanism, resulting in the insertion mechanism needing to be quite long to penetrate the soil. An excessively long insertion mechanism is not conducive to carrying and transportation. Utility Model Content

[0005] The present invention aims to provide a backfill soil thickness measuring device to solve the problem mentioned above that the existing insertion mechanism is too long and not conducive to carrying and transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a backfill soil thickness measuring device, comprising...

[0007] The base plate is equipped with ground nails around its perimeter. Upright plates are fixed to both sides of the base plate. The side walls of the upright plates are provided with grooves, and the upright plates are marked with graduations along the grooves.

[0008] The insertion mechanism includes a cone rod, a top plate, a guide ring, and a limiting ring. The limiting ring is installed on the bottom plate and threaded onto the cone rod. The bottom edge of the cone rod can extend to below the bottom edge of the bottom plate. The guide ring is rotatably installed on the cone rod, and a marking plate is fixed on both sides of the guide ring. The marking plate slides with the slide groove. The top plate is fixed to the top of the cone rod.

[0009] Extension rod assembly, which can be detachably installed on the top plate.

[0010] The principle and effects of this technical solution:

[0011] 1. The cone rod is guided by the guide ring and the cone rod is threadedly engaged with the limiting ring, allowing the cone rod to be raised and lowered relative to the base plate by rotation. The rotation method also facilitates the cone rod to penetrate the soil layer. The insertion mechanism is extended by the detachable extension rod, allowing the user to avoid interference from the vertical plate when controlling the insertion mechanism. At the same time, the space occupied by the device can be reduced by disassembling it when carrying and storing it.

[0012] 2. By driving the ground nails into the soil, the position of the base plate can be stabilized. With the setting of guide rings and marker plates, the penetration depth of the cone rod can be observed through the corresponding scale on the track of the marker plate. At the same time, the track can guide the movement of the marker plate and guide ring, that is, guide the cone rod.

[0013] The present invention is further configured such that: an annular guide rail is fixed to the top of the guide ring, and a connecting bolt is slidably fitted inside the annular guide rail, with the top surface of the connecting bolt fixed to the top plate.

[0014] The principle and effect of this technical solution: By cooperating with the connecting bolt and the annular guide rail, the guide ring can be suspended below the connecting bolt through the annular guide rail, and the connecting bolt can rotate relative to the annular guide rail. The connection between the connecting bolt and the top plate allows the top plate to rotate relative to the guide ring while keeping the distance between the guide ring and the top plate constant, thus not hindering the rotation of the cone rod.

[0015] The present invention is further configured such that the inner cavity cross section of the annular guide rail is inverted "T" shape.

[0016] The principle and effect of this technical solution: The T-shaped design allows the annular guide rail to not only guide the connecting bolts, but also to limit their position.

[0017] The present invention is further configured such that: the extension rod assembly includes an extension rod, a handle, a connecting plate and a connecting nut, the connecting rod is fixed on the top plate, the connecting plate is slidably fitted on the connecting rod, the connecting nut is threadedly fitted on the connecting rod, and the bottom surface of the connecting nut abuts against the top surface of the connecting plate, the extension rod is fixed on the connecting plate, and the handle is fixed on the top of the extension rod.

[0018] The principle and effect of this technical solution: Through the sliding fit between the connecting plate and the connecting rod, the connecting rod can limit the connecting plate, so that the connecting plate can only move vertically relative to the connecting rod. Furthermore, through the connection nut engaging with the connecting rod, the connecting plate can be stably installed on the top plate. Thus, the extension rod can keep in sync with the top plate and the cone rod. At the same time, the restriction on the connecting plate can be released by rotating the connection nut.

[0019] The present invention is further configured such that: a slot is provided on the side wall of the base plate, and an insert plate is slidably fitted in the slot, the bottom surface of the insert plate being flush with the bottom surface of the base plate.

[0020] The principle and effect of this technical solution: By setting up the insert plate, the user can pull out the insert plate to a certain length and then step on it, so that the user can firmly press the bottom plate into the soil surface through the force of stepping on it, thereby overcoming the reaction force when the cone rod is turned into the soil.

[0021] The present invention is further configured such that the ground nail is threaded into the base plate, and the bottom edge of the ground nail extends to the bottom edge of the base plate.

[0022] The principle and effect of this technical solution: By using threaded insertion, the ground nails can be removed and replaced relative to the base plate, and the length of the ground nails extending to the bottom edge of the base plate can also be adjusted.

[0023] The present invention is further configured such that: the bottom surface of the limiting ring is fixed with support rods at intervals, and the support rods are fixed to the base plate.

[0024] The principle and effect of this technical solution: By setting the support rod, the limiting ring can be lifted a certain distance away from the bottom plate, so that the soil brought out by the cone rod when drilling can be discharged from the gap between the support rods, thereby avoiding the obstruction of the soil by the limiting ring and reducing the impact of the soil on the cooperation between the limiting ring and the cone rod.

[0037] Example:

[0038] As attached Figure 1-6 As shown, this utility model discloses a backfill soil thickness measuring device, including a base plate 110, an insertion mechanism and an extension rod assembly. Ground nails 120 are threadedly inserted around the top surface of the base plate 110, and the bottom edge of the ground nails 120 extends to the bottom edge of the base plate 110. Vertical plates 130 are fixed on both sides of the base plate 110. Each vertical plate 130 has a sliding groove 131 on its side wall, and the vertical plate 130 has a scale along the sliding groove 131. A slot 111 is opened on the side wall of the base plate 110, and an insert plate 112 is slidably fitted in the slot 111. The bottom surface of the insert plate 112 is flush with the bottom surface of the base plate 110.

[0039] The insertion mechanism includes a cone rod 210, a top plate 220, a guide ring 230, and a limiting ring 240. Support rods 241 are fixed at intervals on the bottom surface of the limiting ring 240. The support rods 241 are fixed to the bottom plate 110. The bottom plate 110 has insertion holes arranged coaxially with the limiting ring 240. The diameter of the insertion holes is larger than the diameter of the cone rod 210 so that the cone rod 210 can make way for the soil when it is inserted into the soil layer. A limiting ring 240 is threaded onto a tapered rod 210. The bottom edge of the tapered rod 210 extends to the bottom edge of the base plate 110 via a insertion hole. A guide ring 230 is rotatably mounted on the tapered rod 210, and marking plates 231 are fixed on both sides of the guide ring 230. The marking plates 231 are slidably engaged with the slide groove 131. A top plate 220 is fixed to the top of the tapered rod 210. An annular guide rail 310 is fixed to the top of the guide ring 230. The inner cavity of the annular guide rail 310 has an inverted "T" shape. A connecting bolt 320 is slidably engaged inside the annular guide rail 310, and the top surface of the connecting bolt 320 is fixed to the top plate 220.

[0040] The extension rod assembly includes an extension rod 410, a handle 420, a connecting plate 430, and a connecting nut 440. A connecting rod 450 is fixed on the top plate 220. The connecting plate 430 is slidably fitted onto the connecting rod 450. The connecting nut 440 is threaded onto the connecting rod 450, and the bottom surface of the connecting nut 440 abuts against the top surface of the connecting plate 430. The extension rod 410 is fixed to the connecting plate 430, and the handle 420 is fixed to the top of the extension rod 410.

[0041] In use, the insert plate 112 can be pulled out of the slot 111 by a certain length, and then the base plate 110 can be pressed onto the soil. At this time, the ground nail 120 is driven into the soil to reinforce the base plate 110. Then, the user can press the base plate 110 firmly onto the soil surface by stepping on the insert plate 112. At this time, the user can rotate the handle 420 to drive the extension rod 410 to rotate. Through the connection plate 430 and the connection rod 450, the top plate 220 is driven, and the cone rod 210 also rotates synchronously. Then, the cone rod 210 moves relative to the limiting ring 240 and penetrates the soil. After the cone rod 210 contacts the rock surface, it is difficult for the cone rod 210 to continue to penetrate. At this time, the user can obtain the thickness of the soil layer by corresponding the scale on the marking plate 231 and the upright plate 130. By rotating the connecting nut 440, the limiting of the connecting plate 430 relative to the top plate 220 can be released to reduce the space occupied by the device when it is carried.

[0042] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
