[0023] As Figure 1 shown:

[0024] A foundation soil layer strength testing device, comprising a bottom plate 1.

[0025] In the present embodiment: the existing announcement number: CN221972326U discloses a foundation soil layer strength testing device, which discloses a base plate in this patent. The bottom plate 1 in the present application file adopts the same technical means in this prior art. This technical means is not described here. For the improvement of this prior art, please refer to the following disclosure technology. To solve the technical problems existing in the prior art, as disclosed in the background art above, "the device can only detect a single point at a time during strength detection, and repeated detection is required when the work load is high, which will affect the progress and efficiency of subsequent construction", in combination with use. This problem is obviously a real problem and is relatively difficult to solve. In view of this, to solve the above-mentioned problems, slide column 2 and slide sleeve 3 are added on this basis.

The surface of the slide sleeve 3 is further fixedly installed with the counterweight 4. The surface of the counterweight 4 is fixedly installed with the positioning ring 5 in sliding connection with the bolt 9 on one side. The other surface of the counterweight 4 is fixedly connected with one end of the detection cone 6. The surface of the base plate 1 is further fixedly installed with the rotating shaft 7. The surface of the rotating shaft 7 is rotatably connected with the connecting frame 8. The surface of the connecting frame 8 is fixedly installed with the bolt 9. The surface of the connecting frame 8 is further rotatably connected with the handle 10.

[0029] In this embodiment: When it is necessary to detect the strength of the ground at a certain position, each counterweight 4 and slide sleeve 3 can be moved to the top end of the slide column 2. The height of the counterweight 4 and the positioning ring 5 is fixed by the bolt 9. Then the device can be moved to the position to be detected. At this time, the worker can hold the handle 10 and rotate between the connecting frame 8 and the rotating shaft 7. The bolt 9 will gradually separate from the positioning ring 5. When the two are completely separated, the counterweight 4 and the slide sleeve 3 will slide along the slide column 2. The detection cone 6 will contact between the ground and the position where the base plate 1 is located under the action of the counterweight 4. The counterweight 4 will apply force to the end of the detection cone 6. The detection cone 6 penetrates into the ground to achieve the purpose of strength detection. The strength of the ground at the position can be determined according to the depth of each detection cone 6 inserted into the ground.

[0030] Further:

[0031] In an optional embodiment, equiangular through holes matching the detection cone 6 are formed on the surface of the base plate 1. The diameter of the through holes formed on the surface of the base plate 1 is greater than the diameter of the detection cone 6.

After the counterweight 4 and the detection cone 6 are stationary, the height of the counterweight 4 and the slide sleeve 3 can be observed to confirm the strength of the ground at the position.

[0033] Further:

[0034] In an optional embodiment, eight slide columns 2 are provided. The eight slide columns 2 are arranged parallel to each other. Two slide columns 2 form a group. Each group of slide columns 2 is equiangularly arranged on the surface of the base plate 1.

[0035] In this embodiment: the slide post 2 arranged in parallel can make the sliding sleeve 3 slide along the surface, and further can make the weight block 4 drive the detection cone 6 to move towards the ground, and can stably perform.

[0036] Further more:

[0037] In an optional embodiment, the sliding sleeve 3 is symmetrically arranged on both sides of the surface of the weight block 4, and the shape of the sliding sleeve 3 is a circular ring-shaped geometric body.

[0041] In this embodiment: the rotating shaft 7 and the connecting frame 8 with the height greater than the height of the slide post 2 can make the slide post 2 not affect the rotating work of the rotating shaft 7 and the connecting frame 8, and can make the connecting and separating work of the pin 9 and the positioning ring 5 be smoothly performed.

[0042] Further more:

[0043] In an optional embodiment, the shape of the pin 9 is an arc shape, and the center of the circle where the pin 9 is located and the rotating shaft 7 are on the same straight line.

[0044] In this embodiment: the pin 9 arranged in an arc shape can drive the pin 9 and the positioning ring 5 to form the connecting and separating work when the rotating work is performed between the connecting frame 8 and the rotating shaft 7, and further can make the weight block 4 perform the free fall motion along the slide post 2 through the sliding sleeve 3.

[0045] The working principle and use process of the device are as follows: when the ground at a position needs to be detected, the weight block 4 and the sliding sleeve 3 can be moved to the top end of the slide post 2, and the height of the weight block 4 and the positioning ring 5 can be fixed through the pin 9, then the device can be moved to the position to be detected, at this time, the worker can hold the handle 10 and make the connecting frame 8 and the rotating shaft 7 rotate, the pin 9 will gradually separate from the positioning ring 5, when the two are completely separated, the weight block 4 and the sliding sleeve 3 will slide along the slide post 2, the detection cone 6 will pass through the position where the bottom plate 1 is located and contact the ground under the action of the weight block 4, the weight block 4 will apply force to the end of the detection cone 6, the detection cone 6 will penetrate into the ground and achieve the purpose of strength detection, and the strength of the ground position can be judged according to the depth of each detection cone 6 inserted into the ground.

[0046] Finally, it should be noted that: the above is only the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement.
