[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 7 , a prefabricated assembled sinking foundation for an additional building elevator, comprising a prefabricated cement layer 1, a plurality of cement frames 2 are arranged outside the prefabricated cement layer 1, the cement frames 2 are fixedly installed on the prefabricated cement layer 1, a storage cavity 201 is formed between the inner wall of the cement frame 2 and the outer wall of the prefabricated cement layer 1, and compressed soil is contained in the storage cavity 201; An extrusion assembly 3 for extruding soil is provided inside the storage cavity 201. The extrusion assembly 3 includes a counterweight block 301. The counterweight block 301 is slidably installed inside the storage cavity 201. The outer wall of the cement frame 2 is provided with a plurality of first discharge ports 202, the interior of the storage cavity 201 is communicated with the exterior of the cement frame 2 through the first discharge ports 202, a plurality of transition grooves 101 are provided inside the lower side of the prefabricated cement layer 1, the transition grooves 101 are communicated with the interior of the storage cavity 201, a second discharge port 102 is provided at the lower end of the transition groove 101, the transition groove 101 is communicated with the exterior lower side of the prefabricated cement layer 1 through the second discharge port 102, and the transition groove 101 is communicated with the interior of the storage cavity 201; The extrusion assembly 3 further includes a vibration motor 302 for driving the counterweight block 301 to vibrate. The vibration motor 302 is fixedly mounted on the upper end of the counterweight block 301 .

[0021] By adopting the above technical solution, after the soil around the precast cement layer 1 is lost, the vibration motor 302 can drive the counterweight block 301 to vibrate continuously after working, thereby surprising the soil inside the storage cavity 201. At this time, the soil in the storage cavity 201 can enter the transition trough 101, and the soil will flow out of the storage cavity 201 and the transition trough 101 through the first discharge port 202 and the second discharge port 102, thereby replenishing the lost soil around.

[0022] The upper end of the storage chamber 201 is rotatably connected to a winding wheel 203, a servo motor 204 is provided on one side of the winding wheel 203, an output end of the servo motor 204 is fixedly connected to the central axis of the winding wheel 203, the servo motor 204 drives the winding wheel 203 to rotate, a pull rope 205 is wound around the outer wall of the winding wheel 203, and the other end of the pull rope 205 is fixedly connected to the upper end of the counterweight block 301; A plurality of extrusion springs 303 are fixedly mounted on the upper end of the counterweight block 301. The upper ends of the extrusion springs 303 are pressed against the inner wall of the storage chamber 201, and one end of the extrusion springs 303 close to the counterweight block 301 presses the counterweight block 301. A feed port 105 is provided at a position of the inner wall of the prefabricated cement layer 1 relative to the storage chamber 201. A one-way valve is installed inside the feed port 105. After opening the one-way valve, the staff can input the prepared soil into the storage chamber 201 through the feed port 105. After the input is completed, the one-way valve is closed. Two switches 106 are fixedly installed on the inner wall of the prefabricated cement layer 1, one of the switches 106 controls the forward and reverse rotation of the servo motor 204, and the other switch 106 controls the start and stop of the vibration motor 302. When the winding wheel needs to work, one of the switches 106 is adjusted to control the servo motor 204 to rotate forward or reverse. When the soil in the storage chamber 201 needs to be squeezed, the other switch 106 is adjusted to control the vibration motor 302 to work, thereby driving the counterweight block 301 to vibrate.

[0023] By adopting the above technical solution, when it is necessary to add soil to the storage chamber 201, the servo motor 204 is controlled to work so that the winding wheel rotates, thereby winding the pull rope 205 through the winding wheel. When it is necessary to compact the soil in the storage chamber 201, the servo motor 204 is first controlled to rotate in the opposite direction so that the pull rope 205 is in a relaxed state, and then the vibration motor 302 is started to drive the counterweight block 301 to vibrate, thereby compacting the soil in the storage chamber 201. The extrusion spring 303 can always squeeze the counterweight block 301 so that the counterweight block 301 is always in close contact with the soil, and when the vibration motor 302 is not working, the soil in the storage chamber 201 is prevented from expanding.

[0024] A plurality of electronic tape measures 103 are embedded in the outer wall of the prefabricated cement layer 1. The number of the electronic tape measures 103 is the same as the number of the cement frames 2, and each electronic tape measure 103 corresponds to one of the cement frames 2. One end of the electronic tape measure 103 is fixedly connected to the upper end of the counterweight block 301. The position of the electronic prefabricated cement layer 1 corresponding to the electronic tape measure 103 is rotatably connected to a guide wheel 104 through a rotating frame, and the outer wall of the guide wheel 104 is in frictional contact with the outer wall of the electronic tape measure 103.

[0025] By adopting the above technical solution, after the counterweight block 301 descends, it can drive the extension end of the electronic tape measure 103 to move, so that the electronic tape measure 103 begins to extend, so that the descending distance of the counterweight block 301 can be recorded by the electronic tape measure 103.

[0026] The inner wall of the prefabricated cement layer 1 is installed with a data processing module 107, a control module 108 and a calculation module 109. The inner wall of the prefabricated cement layer 1 is also installed with an alarm 110. The electronic tape measure 103 transmits the elongation data to the data processing module 107. The data processing module 107 analyzes the data collected by the electronic tape measure 103. When the elongated length data of the electronic tape measure 103 is transmitted to the control module 108, a decision tree model is trained by the data of the electronic tape measure 103. When the elongated length of the electronic tape measure 103 reaches a certain length, the control module 108 controls the alarm 110 to alarm. A display screen 111 is installed inside the prefabricated cement layer 1. The elongation data of the electronic tape measure 103 is transmitted to the display screen 111 and displayed by the display screen 111. The calculation module 109 calculates the volume of soil that needs to be added to the storage chamber 201 according to the volume of soil discharged from the storage chamber 201 by the following formula: ; Wherein, V is the volume of soil to be replenished, N is the area of ​​the lower end of the counterweight block 301, ρ1 is the density of the compacted soil in the storage chamber 201, ρ0 is the relaxed soil density, and L is the distance the counterweight block 301 descends; The calculation module 109 calculates the total amount of soil lost around the prefabricated cement layer 1 according to the following formula: ; Where V 总 is the total amount of soil lost around the prefabricated cement layer 1, V i The calculation module 109 transmits the calculated total amount of soil to be replenished and the amount of soil to be replenished in each storage chamber 201 to the display screen 111 for display on the display screen 111 .

[0027] By adopting the above technical solution, when the counterweight block 301 drops a certain distance, the length of the electronic measuring tape 103 becomes longer. When the amount of soil stored in the storage cavity 201 is insufficient, the control module 108 will control the alarm 110 to sound an alarm, reminding the staff to replenish the soil in time. Among them, the display screen 111 can display the extended length of the electronic measuring tape 103. The staff can replenish the soil in the storage cavity 201 in advance according to work needs. The calculation module 109 can determine the amount of soil that needs to be replenished in each storage cavity 201 according to the distance moved by the counterweight block 301, and can calculate the total amount of soil needed, so that the staff can prepare the appropriate amount of soil.

[0028] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
