[0027] Embodiment 1: A foundation detection device comprises a foundation base layer 1, two side piers 2 are symmetrically arranged on both sides of the top of the foundation base layer 1, top limit grooves 3 are opened on the tops of the side piers 2, two limit blocks 4 slide symmetrically in the top limit grooves 3, a weight platform 5 is arranged above the foundation base layer 1, both sides of the bottom end of the weight platform 5 are fixedly connected to the top of the limit block 4, a number of counterweight blocks 6 are evenly arranged on the top of the weight platform 5, a foundation pressure detection component 7 for detection is arranged on the top of the foundation base layer 1, and two groups of pressure displacement detection components 8 are symmetrically arranged around the top of the foundation base layer 1.

[0028] The foundation pressure detection assembly 7 includes a pressure plate 701 arranged in the middle of the top of the foundation base layer 1, a jack 702 is arranged above the pressure plate 701, a mounting plate 703 is arranged at the top of the pressure plate 701, four pressure detectors 704 are evenly arranged at the bottom end of the jack 702, the bottom end of the pressure detector 704 is fixed to the mounting plate 703, a reaction beam 705 is arranged above the jack 702, the top surface of the reaction beam 705 is in conflict with the bottom end surface of the weight platform 5, and two support plugs 706 are symmetrically arranged at the top of the foundation base layer 1, and a connecting rod 707 is slidably inserted at the top of the support plug 706, and the top end of the connecting rod 707 is connected to the bottom end surface of the reaction beam 705.

[0029] The compressed displacement detection component 8 includes a side connecting plate 801 arranged around the top of the foundation base layer 1, and a displacement sensor 802 is installed on the inner side of the side connecting plate 801. Two fixed blocks 803 are symmetrically arranged at the bottom ends of both sides of the side connecting plate 801. Fixed sockets 804 are provided on the fixed blocks 803. Four fixed screw holes 806 are symmetrically provided on the foundation base layer 1. Fastening screws 805 are inserted into the fixing sockets 804, and the bottom ends of the fastening screws 805 extend into the fixing screw holes 806.

[0030] Embodiment 2: The difference between this embodiment and embodiment 1 is that the pressure detectors 704 are evenly located around the bottom end of the jack 702.

[0031] The jack 702 is started to support the weight platform 5, and the user can detect the specific value of the pressure on the foundation base 1 through the pressure detector 704 set at the bottom of the jack 702, so as to obtain the foundation pressure value more conveniently.

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that the displacement sensors 802 are located at the edges of both sides of the pressure plate 701 .

[0033] This allows the displacement sensor 802 to more accurately record the displacement of the pressure plate 701 when it is under pressure.

[0034] Example 4: The difference between this example and Example 1 is that two fixing screws 9 are symmetrically threadedly inserted at the top of the side of the side pier 2, and the ends of the fixing screws 9 extend into the top limiting groove 3.

[0035] When a plurality of counterweight blocks 6 are not placed on the weight platform 5 , the limiting block 4 at the bottom of the weight platform 5 can be fixed by rotating the fixing screw 9 .

[0036] In this embodiment, since the existing foundation detection device often uses the analysis of foundation soil samples to preliminarily judge the supporting capacity of the foundation during actual use, this judgment method lacks the necessary experimental data and can only provide a certain reference during the actual detection process, and cannot provide more realistic foundation detection data.

[0037] In summary, in the specific implementation, when the user needs to test the pressure value that the foundation base layer 1 can withstand, the user first needs to symmetrically set two side piers 2 on the foundation base layer 1, and set a weight platform 5 on the top of the side piers 2. By continuously stacking counterweight blocks 6 on the weight platform 5, the weight above the weight platform 5 is increased.

[0038] Next, the user activates the jack 702 in the foundation pressure detection assembly 7 provided in the middle of the bottom end of the weight platform 5, so that the jack 702 can be lifted up, and then move upward together with the counterweight block 6 above the weight platform 5. At this time, the pressure detector 704 provided at the bottom of the jack 702 can detect and record the pressure borne by the jack 702, and the pressure will also resist the pressure plate 701 through the mounting plate 703, so that the user can also observe the force condition of the pressure plate 701 to observe the changes in the foundation base 1 during the pressure process.

[0039] The displacement sensor 802 in the pressure displacement detection component 8 can monitor the position of the mounting plate 703 on the pressure plate 701, so as to accurately determine the displacement distance of the mounting plate 703 on the surface of the pressure plate 701 when the pressure plate 701 is under pressure, so as to detect the pressure friction condition of the surface of the foundation base 1, and then through a real pressure test, more accurate detection test data can be obtained, thereby providing convenience for users' research and detection.
