Description

Technical Field

[0001] The utility model belongs to the technical field of settlement monitoring, in particular to a multi-directional detection foundation settlement monitoring instrument. Background Art

[0002] Before the construction of buildings and geotechnical structures, the self-weight stress caused by the gravity of the soil has already existed in the foundation. The load of buildings and geotechnical structures is transmitted to the foundation through the bottom surface of the foundation or embankment, which changes the original stress state of the natural soil layer. Under the action of the additional three-dimensional stress components, vertical, lateral and shear deformations are generated in the foundation, resulting in vertical and lateral displacements of each point.

[0003] Foundation settlement refers to the sinking of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. A monitoring device is needed to detect how far the foundation sinks, the limiting structure to guide the sinking structure to descend, and the push rod to sink accurately.

[0004] Existing foundation settlement detection devices can usually only detect deformation and settlement in the vertical direction, and cannot simultaneously detect the vertical and lateral deformation and settlement around the device, which makes the detection not comprehensive enough, resulting in the failure to discover the foundation settlement in time, which can easily lead to accidents. Therefore, a foundation settlement monitoring instrument with multi-directional detection is proposed to address the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 4The utility model provides a foundation settlement monitoring instrument with multi-directional detection, comprising a fixed plate 1: a fixed frame 2 is fixed on the top of the fixed plate 1; a sliding rod 4 is vertically fixed on the inner side of the fixed frame 2; a sliding block 21 is slidably connected to the outer side of the sliding rod 4; a fixed rod 3 is fixed to one end of the sliding block 21; a mobile measuring rod 5 is slidably connected to the end of the fixed rod 3 away from the sliding block 21; a fixed block 6 is fixed to the end of the mobile measuring rod 5 away from the fixed rod 3; a sinking rod 7 is fixed to the lower end of the fixed block 6; a sinking block 8 is fixed to the lower end of the sinking rod 7; a transmission assembly is arranged on the inner side of the sinking block 8; and the instrument is used for monitoring the lateral displacement of the foundation. During operation, when monitoring is required, first fix the fixed plate 1 on the ground that will not settle next to the foundation to be monitored, and then pre-bury the settlement block 8 into the foundation to be measured. When the foundation vertically settles, the settlement block 8 and the fixed block 6 will drive the fixed rod 3 and the sliding block 21 to move downward, and then it can be judged whether the foundation has settled by observing whether the sliding block 21 has descended. When the foundation moves and tilts forward and backward, the settlement block 8 and the sinking rod 7 will drive the fixed block 6 and the mobile measuring rod 5 to move, so that it can be judged by observing the elongation length of the mobile measuring rod 5. When the foundation is displaced left and right, the displacement is monitored through the transmission assembly. This step can effectively monitor and measure the displacement in time when the foundation is horizontally displaced through the coordinated structural design of the transmission assembly, the sinking rod 7 and the fixed block 6. At the same time, through the structural design of the fixed rod 3, the mobile measuring rod 5 and the sliding block 21, the settlement can be monitored when the foundation settles, thereby effectively reducing the damage to the building caused by foundation settlement or horizontal displacement, and improving the practicality of the device.

[0026] Further, such as Figure 2As shown, the transmission assembly includes a moving frame 13; the moving frame 13 is arranged on the inner side of the sinker block 8; the moving frame 13 is slidably connected to the sinker block 8; the inner side of the sinker rod 7 is rotatably connected with a transmission rod 15; the two ends of the transmission rod 15 extend to the inner sides of the fixed block 6 and the sinker block 8 respectively; a first gear 16 is fixed to one end of the transmission rod 15 located on the inner side of the sinker block 8; a first rack 14 is fixed to the inner side of the moving frame 13 and at a position corresponding to the first gear 16; the first rack 14 is meshingly connected with the first gear 16; connecting rods 10 are fixed to both ends of the moving frame 13; the end of the connecting rod 10 away from the moving frame 13 extends to the outside of the sinker block 8; a contact plate 9 is fixed to one end of the connecting rod 10 located on the outside of the moving frame 13; an observation assembly is provided on the inner side of the fixed block 6. During operation, when the foundation is displaced left or right, the contact plate 9 will be squeezed, so that the contact plate 9 drives the movable frame 13 to move through the connecting rod 10. When the movable frame 13 moves, it drives the first rack 14 to move at the same time. The first rack 14 drives the transmission rod 15 to rotate through the first gear 16 meshing with it. This step can drive the movable frame 13 and the first rack 14 to move through the contact plate 9 and the connecting rod 10 when the foundation is displaced left or right, so that the transmission rod 15 can be driven to rotate through the first gear 16, and then the observation component can be driven by the rotation of the transmission rod 15, so that the left and right displacement of the foundation can be observed and monitored through the observation component, thereby improving the multi-directional monitoring of the device and the accuracy of foundation monitoring.

[0027] Further, such as Figure 3 As shown, the observation assembly includes a second gear 17; the second gear 17 is fixed to one end of the transmission rod 15 located inside the fixed block 6; a second rack 18 is slidably connected to the position inside the fixed block 6 and corresponding to the second gear 17; the second rack 18 is meshed and connected with the second gear 17. During operation, when the transmission rod 15 rotates, the second gear 17 is driven to rotate, and when the second gear 17 rotates, the second rack 18 meshed and connected therewith is driven to move. This step can drive the second rack 18 to move through the second gear 17 when the transmission rod 15 rotates.

[0028] like Figure 3As shown, an extension rod 19 is fixed to the side of the second rack 18 away from the second gear 17; a first pointer 20 is fixed to the end of the extension rod 19 away from the second rack 18; and a second scale 24 is fixed to the position of the fixed block 6 corresponding to the first pointer 20. During operation, when the second rack 18 moves, the extension rod 19 fixed thereto moves simultaneously, and when the extension rod 19 moves, the first pointer 20 moves simultaneously, and then the second scale 24 corresponding to the movement of the first pointer 20 can be observed. This step can drive the extension rod 19 and the first pointer 20 to move simultaneously when the second rack 18 moves, and then the left and right displacement of the foundation can be monitored through the second scale 24 corresponding to the movement of the first pointer 20.

[0029] like Figure 2 As shown, telescopic rods 11 are fixed on both sides of the end of the sinker 8 close to the contact plate 9; the telescopic end of the telescopic rod 11 is fixedly connected to the contact plate 9; a reset spring 12 is sleeved on the outer side of the telescopic rod 11; one end of the reset spring 12 is fixedly connected to the sinker 8; and the other end of the reset spring 12 is fixedly connected to the contact plate 9. During operation, when the contact plate 9 moves, the reset spring 12 is squeezed, so that the reset spring 12 undergoes elastic deformation to store energy. When the force applied to the contact plate 9 disappears, the contact plate 9 is pushed away from the sinker 8 under the elastic action of the reset spring 12. Through the design of two groups of reset springs 12 and the contact plate 9, the mobile frame 13 can be in the middle position. This step can limit the contact plate 9 through the reset spring 12, thereby preventing the contact plate 9 from moving at will, causing the mobile frame 13 to move, thereby affecting the monitoring results, and improving the stability of the mobile frame 13.

[0030] like Figure 3 As shown, a third scale 25 is fixed on one side of the mobile measuring rod 5. During operation, when the foundation moves forward and backward, the settlement block 8 and the sinking rod 7 drive the mobile measuring rod 5 to move through the fixed block 6. When the mobile measuring rod 5 moves, the forward and backward displacement of the foundation can be quantitatively observed by the position of the third scale 25 at the contact position between the fixed rod 3 and the mobile measuring rod 5. This step can facilitate the observation of the forward and backward displacement of the foundation.

[0031] like Figure 4As shown, a second pointer 22 is fixed to one side of the sliding block 21; a first scale 23 is fixed to the position of the fixed frame 2 corresponding to the second pointer 22. During operation, when the foundation settles, the settlement block 8 and the sinking rod 7 will be driven to move downward. When the sinking rod 7 moves, the fixed rod 3 will be driven to move simultaneously through the fixed block 6 and the movable measuring rod 5. When the fixed rod 3 moves, the sliding block 21 will be driven to move, so that the sliding block 21 drives the second pointer 22 to move simultaneously, and then the foundation settlement can be observed through the position of the first scale 23 corresponding to the second pointer 22. This step can facilitate monitoring whether the foundation has settled, and at the same time, the degree of settlement can be quantified through the first scale 23, which is convenient for judging the degree of settlement.

[0032] Working principle: When monitoring is required, first fix the fixed plate 1 on the ground that will not settle next to the foundation to be monitored, and then pre-bury the settlement block 8 into the foundation to be measured. When the foundation settles vertically, the settlement block 8 and the fixed block 6 will drive the fixed rod 3 and the sliding block 21 to move downward, and then it can be judged by observing whether the sliding block 21 descends. When the foundation moves forward and backward and tilts, the settlement block 8 and the sinking rod 7 will drive the fixed block 6 and the mobile measuring rod 5 to move, so that it can be judged by observing the elongation length of the mobile measuring rod 5. When the foundation moves left and right, the sensor The movable assembly is used to monitor the displacement; when the foundation moves left and right, the contact plate 9 is squeezed, so that the contact plate 9 drives the mobile frame 13 to move through the connecting rod 10, and when the mobile frame 13 moves, it drives the first rack 14 to move at the same time, and the first rack 14 drives the transmission rod 15 to rotate through the first gear 16 meshing with it; when the transmission rod 15 rotates, it drives the second gear 17 to rotate, and when the second gear 17 rotates, it drives the second rack 18 meshing with it to move; when the second rack 18 moves, it drives the extension rod 19 fixed to it to move at the same time, and when the extension rod 19 moves, it drives When the contact plate 9 moves, the first pointer 20 moves at the same time, and then the second scale 24 corresponding to the movement of the first pointer 20 can be observed; when the contact plate 9 moves, the reset spring 12 is squeezed, so that the reset spring 12 undergoes elastic deformation to store energy. When the force applied to the contact plate 9 disappears, the contact plate 9 is pushed away from the sinker 8 under the elastic action of the reset spring 12. The design of the two sets of reset springs 12 and the contact plate 9 allows the moving frame 13 to be in the middle position; when the foundation moves forward and backward, the sinker 8 and the sinking rod 7 drive the mobile measuring rod 5 to move through the fixed block 6. When the mobile measuring rod 5 moves, the forward and backward displacement of the foundation can be quantitatively observed through the position of the third scale 25 at the contact position between the fixed rod 3 and the mobile measuring rod 5; when the foundation settles, it will drive the settlement block 8 and the sinking rod 7 to move downward, and when the sinking rod 7 moves, it will drive the fixed rod 3 to move at the same time through the fixed block 6 and the mobile measuring rod 5. When the fixed rod 3 moves, it will drive the sliding block 21 to move, so that the sliding block 21 drives the second pointer 22 to move at the same time, and then the situation of the foundation settlement can be observed through the position of the first scale 23 corresponding to the second pointer 22.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
