Description

Technical Field

[0001] The utility model relates to the technical field of foundation settlement detection equipment, in particular to a foundation settlement detection instrument. Background Art

[0002] 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. Excessive settlement, especially uneven settlement, will cause the building to tilt, crack and become unusable. Therefore, it is necessary to observe this phenomenon so as to deal with this problem in a targeted manner. An important point in foundation settlement detection is to find a reference point outside the area to be detected so that the base of the detection instrument can be placed. However, the outdoor environment is complex and diverse, and there is a certain angle deviation between the foundation of the area to be detected and the reference point. Therefore, it is necessary to process the terrain of the reference point in advance, which brings additional workload to the detection work, and some places are more difficult to handle. In view of this, we propose a foundation settlement detector. Utility Model Content

[0003] The utility model aims to solve the shortcomings of existing foundation settlement detection equipment that it is difficult to adjust the detection angle according to the specific environment, which increases the extra workload for the detection work, and proposes a foundation settlement detection instrument.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A foundation settlement detector comprises a mounting base, on which a detection component capable of adapting to different mounting angles of the mounting base is provided;

[0006] The detection component includes a fixed frame fixedly installed on a mounting base, an adjusting rod is rotatably installed on the fixed frame, a sliding cavity is opened on the adjusting rod, and a measuring rod is slidably installed through the sliding cavity, and an insertion rod in contact with the foundation is provided at the bottom of the measuring rod, and a fixing component for fixing the adjusting rod is provided on the fixed frame.

[0007] Preferably, the fixing assembly includes a fixing worm rotatably mounted in a fixing frame, one end of the fixing worm penetrates the fixing frame and is provided with a rotating end, and the outside of the fixing worm is meshed with a fixing worm wheel coaxially fixed with the adjusting rod.

[0008] Preferably, the outermost end of the rotating end is set to a smooth spherical surface, which can reduce the time that external impurities stay on the rotating end, reduce the probability of the rotating end exposed to the outside world being corroded, and extend the service life of the rotating end.

[0009] Preferably, a level cavity is provided on the adjusting rod, so that the staff can more intuitively observe whether the adjusting rod is placed horizontally through the water bubble in the level cavity, thereby improving the accuracy of settlement data measurement.

[0010] Preferably, the insertion rod is rotatably connected to the measuring rod, and a driving end face is provided at the connection. The insertion rod is externally sleeved with a soil drilling blade, and the setting of the soil drilling blade facilitates the discharge of soil in the foundation and reduces the resistance encountered when the insertion rod is inserted into the ground.

[0011] Preferably, a guide groove is provided on the inner wall of the sliding cavity, and a guide block fixed to the measuring rod is slidably installed in the guide groove. This arrangement increases the contact area between the measuring rod and the sliding cavity, improves the stability of the measuring rod movement, and ensures the accuracy of the sedimentation data.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model realizes the detection of foundation settlement data through the setting of the detection component, and through the free rotation of the adjustment rod, the device can adapt to the measurement of most terrains. Compared with the traditional method, there is no need to clean the reference point, which reduces a large number of work steps and reflects the practicality of the device.

[0014] 2. The utility model enables the insertion rod to be inserted deep into the foundation through the coordination of structures such as the soil drilling blade and the driving end face, thereby avoiding the influence of changes in the foundation surface on the detection results and further improving the accuracy of data detection. In addition, the setting of the guide block and the guide groove increases the contact area between the measuring rod and the sliding cavity, thereby improving the stability of the measuring rod movement.

[0015] 3. The utility model uses the unique self-locking performance of the worm wheel and the worm to ensure that the adjusting rod coaxially fixed with the fixed worm wheel will not rotate easily under the influence of external force, thereby achieving the fixation of the position of the adjusting rod.

DETAILED DESCRIPTION

[0020] 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.

[0021] In order to prevent foundation settlement, a series of measures need to be taken. For example, strengthening the foundation, doing a good job of earthwork on the foundation slope, and improving geological conditions. However, this requires the previous record of foundation settlement data so that this problem can be better solved. However, the terrain of the detection area is relatively complex, and it is not easy to determine a good benchmark point, which has a certain impact on the installation of the detection equipment. To solve the above defects, we proposed the following solution.

[0022] Embodiment 1

[0023] Existing foundation settlement detection equipment is not easy to adjust the detection angle according to the specific environment, which adds extra workload to the detection work. Figure 1-Figure 3 This embodiment proposes a foundation settlement detector, which realizes the detection of foundation settlement data, and through the free rotation of the adjustment rod 22, the device can adapt to the measurement of most terrains. Compared with the traditional method, there is no need to clean the reference point, which reduces a lot of work steps. It is mainly composed of an installation base 1, and the installation base 1 is provided with a detection component 2 that can adapt to different installation angles of the installation base 1. When performing foundation settlement detection, it is necessary to first install the installation base 1 to a position outside the area to be detected, and then perform detection through the detection component 2.

[0024] In order to make the detection equipment suitable for settlement detection in most terrains, the present embodiment proposes a detection component 2, which reduces the probability of cleaning the reference point, reduces a part of the workload, and improves the installation efficiency of the detection equipment. Figure 1As shown, the detection component 2 includes a fixed frame 21 fixedly mounted on the mounting base 1, an adjusting rod 22 is rotatably mounted on the fixed frame 21, a sliding cavity is opened on the adjusting rod 22, and a measuring rod 24 is slidably mounted through the sliding cavity, and a plug rod 25 in contact with the foundation is provided at the bottom of the measuring rod 24, and a fixing component 29 for fixing the adjusting rod 22 is provided on the fixed frame 21. After the mounting base 1 is installed, the adjusting rod 22 can be rotated to an angle horizontal to the foundation of the detection area, and then the adjusting rod 22 is fixed by the fixing component 29 so that it is not easy to rotate under the action of external force, and then the tail end of the plug rod 25 is placed on the foundation of the detection area, and the data on the measuring rod 24 at this time is recorded, which is recorded as A1. After a period of time, the number on the measuring rod 24 is observed again and recorded as A2. Therefore, the settlement data of this area is A1-A2. This measurement and detection method is suitable for reference points of different terrains. Compared with the traditional method, there is no need to clean the reference points, which reduces a large number of work steps and reflects the practicality of the device.

[0025] The outdoor environment is relatively complex and there are many interference factors. The adjusting rod 22 is easily tilted under the action of external force, thereby affecting the final observation data. In this embodiment, the effect of fixing the adjusting rod 22 is achieved by setting a fixing component 29. The fixing component 29 includes a fixed worm 291 rotatably installed in the fixing frame 21, and one end of the fixed worm 291 passes through the fixing frame 21 and is installed with a rotating end 293. The fixed worm 291 is externally meshed with a fixed worm wheel 292 coaxially fixed with the adjusting rod 22. When controlling the rotation of the adjusting rod 22, the rotation of the fixed worm 291 can be controlled by the rotating end 293. The position of the adjusting rod 22 can be adjusted in real time through the meshing relationship between the fixed worm 291 and the fixed worm wheel 292. Because of the unique self-locking performance of the worm wheel and the worm, the adjusting rod 22 coaxially fixed with the fixed worm wheel 292 will not easily rotate under the influence of external force, thereby achieving the fixation of the position of the adjusting rod 22.

[0026] The outermost end of the rotating end 293 is set as a smooth spherical surface. The setting of the smooth spherical surface reduces the time that external impurities stay on the rotating end 293, reduces the probability of the rotating end 293 exposed to the outside world being corroded, and extends the service life of the rotating end 293.

[0027] A level cavity 23 is provided on the adjusting rod 22. When the adjusting rod 22 is controlled to rotate, the staff can more intuitively observe whether the adjusting rod 22 is placed horizontally through the water bubble in the level cavity 23, thereby improving the accuracy of the settlement data measurement.

[0028] Embodiment 2

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the shortcomings of existing foundation settlement detection equipment that it is difficult to adjust the detection angle according to the specific environment, which adds extra workload to the detection work. However, under the influence of wind and sun, the height of the foundation surface is easy to change, but this is not necessarily caused by foundation settlement. The measuring blocks used in existing foundation settlement equipment are generally placed directly on the foundation surface, which makes the measurement data of the settlement data have large errors.

[0030] Reference Figure 1-Figure 3 The insertion rod 25 is rotatably connected to the measuring rod 24, and a driving end face is provided at the connection. A soil-boring blade 26 is sleeved on the outside of the insertion rod 25. In this embodiment, the soil-boring blade 26 is provided so that when the staff installs the equipment, they can insert the insertion rod 25 deep into the foundation by rotating the driving end face, thereby avoiding the influence of the foundation surface on it and further improving the accuracy of equipment detection.

[0031] A guide groove 27 is provided on the inner wall of the sliding cavity, and a guide block 28 fixedly connected to the measuring rod 24 is slidably installed in the guide groove 27. The setting of the guide block 28 and the guide groove 27 increases the contact area between the measuring rod 24 and the sliding cavity, thereby improving the stability of the movement of the measuring rod 24 and ensuring the accuracy of the settlement data.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
