[0002] A foundation pit refers to a deep pit excavated during building construction, that is, a pit dug in advance for building components in the construction industry. The excavation of the foundation pit is an important link in construction engineering, but it also faces some engineering technical problems and safety risks. The construction of the foundation pit needs to take corresponding support measures according to specific situations to ensure the safe progress of the project. Before excavating the foundation pit, it is necessary to detect the earth pressure of the foundation pit in order to timely discover potential safety hazards and ensure the safe progress of the foundation pit construction.

[0003] The utility model with the publication number of CN217084429U discloses an earth pressure detection device for foundation pit detection, which relates to the field of foundation pit detection.

[0032] In this embodiment, the mounting plate 1 provided in the earth pressure detection device for foundation pit detection can limit the installation position of the driving mechanism 2. When the driving mechanism 2 is started, it can drive several adjusting mechanisms 3 to rotate simultaneously. The number of the provided adjusting mechanisms 3 can be greater than or equal to three, and they are arranged around the driving mechanism 2 in a circle. While the adjusting mechanism 3 is rotating, under the limitation of the mounting plate 1, it can adjust the rectangular extension bar 4 threadedly connected to the adjusting mechanism 3 to move. And the number of the rectangular extension bars 4 matches that of the adjusting mechanism 3. Thus, when several adjusting mechanisms 3 rotate simultaneously, it can synchronously adjust several rectangular extension bars 4 to expand and contract.

A pressure detection component 6 is fixedly connected to the lower surface of the mounting plate 1. Starting the pressure detection component 6 can detect the earth pressure of the foundation pit. Further, a universal wheel 7 is fixedly connected to the lower end surface of the support leg 5. Thus, when adjusting the position of the support leg 5, the provided universal wheel 7 can facilitate the movement of the support leg 5, thereby enhancing the movement adjustment effect of the support leg 5 and making this application more conducive to practical use.

[0033] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, the pressure detection component 6 includes a hydraulic cylinder 601 fixedly connected to the lower surface of the mounting plate 1.

A first bevel gear 203 is fixedly connected to the outer wall of the shaft rod 202, and the outer wall of the first bevel gear 203 meshes with the outer wall of one end of the adjusting mechanism 3.

[0036] In this embodiment, the starting motor 201 can drive the shaft rod 202 to rotate.

[0038] In this embodiment, the second bevel gears 301 on the outer wall of the first bevel gear 203 are meshed and connected. Therefore, when the first bevel gear 203 rotates, it can control the meshed second bevel gear 301 to rotate. By the rotation of the second bevel gear 301, the threaded rod 302 can be controlled to rotate. While the threaded rod 302 rotates, the rectangular extension strip 4 can be adjusted to move under the limitation of the mounting plate 1.

[0039] In a further preferred embodiment of the present utility model, as Figure 2 shown, a limiting plate 8 is arranged outside the threaded rod 302. The outer wall of the limiting plate 8 is fixedly connected to the inner wall of the mounting plate 1. A bearing 9 is arranged between the contact surface of the inner wall of the limiting plate 8 and the outer wall of the threaded rod 302.

[0042] In this embodiment, the installation position of the limiting component 11 can be limited through the opened storage groove 10. The arranged limiting component 11 can be adjusted to move up and down inside the storage groove 10 as needed. When the limiting component 11 moves down, the bottom end can be inserted into the soil, thereby limiting the support leg 5 and preventing the present application from moving randomly during detection.

[0043] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 4As shown in the figure, it includes a limiting insertion post 1101 located inside the storage slot 10.

[0044] In this embodiment, the user can control the downward movement of the limiting insertion post 1101 to insert it into the soil by stepping on the pedal 1103, which can limit the support leg 5. At the same time when the limiting insertion post 1101 moves downward, the set insertion cone 1102 can reduce a certain amount of resistance.

[0045] The implementation principle of the soil pressure detection device for foundation pit detection in the embodiment of the present application is as follows:

[0046] When in use, place the soil pressure detection device for foundation pit detection of the present application above the position where the foundation pit needs to be excavated. Start the driving mechanism 2 to drive several adjusting mechanisms 3 to rotate simultaneously. While the adjusting mechanism 3 is rotating, under the limitation of the mounting plate 1, the rectangular extension bar 4 threadedly connected to the adjusting mechanism 3 can be adjusted to move. By the movement of the rectangular extension bar 4, the support leg 5 installed on the lower surface of the rectangular extension bar 4 can be adjusted to move, so that the position of the support leg 5 can be adjusted and supported according to foundation pits of different sizes. And when adjusting the position of the support leg 5, the universal wheel 7 fixedly installed on the lower end surface of the support leg 5 can facilitate the movement of the support leg 5, thereby enhancing the movement adjustment effect of the support leg 5 and making the present application more conducive to practical use.

[0047] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this.
