Description

Technical Field

[0001] This utility model relates to the field of building construction safety monitoring technology, and more specifically, to a deep foundation pit retaining structure deformation monitoring device. Background Technology

[0002] In deep foundation pit construction, the stability of the retaining structure is crucial. To ensure construction safety, it is necessary to monitor the deformation of the retaining structure in real time. The deformation of the retaining structure mentioned here mainly refers to the situation where the retaining structure tilts under the action of the foundation pit wall. In order to facilitate the real-time monitoring of the tilting deformation of the retaining structure, it is necessary to install a deep foundation pit retaining structure deformation monitoring device.

[0003] A search revealed a Chinese utility model with publication number "CN221259856U", which discloses a deformation monitoring device for deep foundation pit retaining structures. The device monitors the deformation of the retaining structure through a structure consisting of a body, an alarm mechanism, a sliding rod, a spring, a baffle, a push rod, a drive device, and a locking mechanism.

[0004] Although the aforementioned document achieves deformation monitoring of the retaining structure, its overall structure is relatively fixed and its size is large, making it very troublesome to install and inconvenient to use. In view of this, we propose a deformation monitoring device for deep foundation pit retaining structures. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a deep foundation pit retaining structure deformation monitoring device to solve the technical problem that the current deep foundation pit retaining structure deformation monitoring device is inconvenient to install and use.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a deep foundation pit retaining structure deformation monitoring device, including an installation structure, an L-shaped installation rod arranged on the installation structure, a scale plate rotatably arranged at the top L-shaped end of the L-shaped installation rod, the scale plate being parallel to the installation structure, and a pointer arranged on the top L-shaped end of the L-shaped installation rod, the pointer corresponding to the scale of the scale plate;

[0007] The dial includes a circular part, the center of which is rotatably arranged with the L-shaped end of the L-shaped mounting rod, and the bottom of the circular part is a triangular plate part, with a counterweight ball arranged at the bottom of the triangular plate part.

[0008] This utility model, through its designed installation structure, L-shaped mounting rod, dial, and pointer, allows for direct fixing of the installation structure to the retaining structure when deformation monitoring of deep foundation pit retaining structures is required. The dial on the L-shaped mounting rod is perpendicular to the retaining structure. Therefore, when the retaining structure tilts backward during its support of the deep foundation pit wall, the installation structure, L-shaped mounting rod, and pointer will tilt synchronously. The dial, under the influence of gravity, will remain vertical and will not rotate. Personnel can then directly determine the tilt angle of the retaining structure by pointing the pointer to the scale on the dial. This facilitates continuous monitoring and understanding of the tilt deformation status of the retaining structure. Thus, the above structure provides effective monitoring of the tilt of the retaining structure. The device for monitoring tilt deformation has a simple and compact overall structure and can be quickly installed on the enclosure structure to monitor its tilt deformation. The scale of this invention consists of a circular disc, a triangular plate, and a counterweight ball. The triangular plate and counterweight ball apply a downward force to the circular disc, ensuring that the scale always maintains its center of gravity downwards. Therefore, when the mounting structure, L-shaped mounting rod, and pointer tilt and deform along with the enclosure structure, the scale remains automatically vertical, preventing rotation and ensuring accurate readings of the tilt deformation angle. This further guarantees the accuracy and convenience of the device in monitoring the tilt deformation of the enclosure structure.

[0009] Preferably, a connecting screw is arranged at the bottom of the triangular plate, and a connecting screw hole is arranged at the top of the counterweight ball, and the connecting screw hole is screwed into the connecting screw.

[0010] Preferably, the mounting structure includes a concave frame, with two sets of symmetrical adjusting screws arranged at the bottom of the concave frame. The adjusting screws extend through the interior of the concave frame and a top fixing plate is arranged at the top. The adjusting screws are rotatably connected to the top fixing plate, and the top of the top fixing plate is provided with anti-slip texture.

[0011] Preferably, a mounting plate is arranged on the top of one side of the concave frame, and a fixing block is arranged at the bottom of the mounting plate. The fixing block is triangular in shape, and one side of the fixing block is connected to the concave frame.

[0012] Preferably, a circular sleeve is arranged at the center of the top of the mounting plate facing away from the concave frame, and symmetrical limiting grooves are opened on both sides inside the circular sleeve. The surface of the L-shaped mounting rod is arranged with limiting protrusions symmetrical to the limiting grooves.

[0013] Preferably, a fixing bolt is arranged on the front side of the circular sleeve, and a fixing screw hole corresponding to the fixing bolt is arranged on the L-shaped mounting rod.

[0014] Preferably, the L-shaped end of the L-shaped mounting rod is provided with a transparent protective sleeve, a sealing cap is screwed onto the rear side of the transparent protective sleeve, and the dial is located inside the transparent protective sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through its designed installation structure, L-shaped mounting rod, dial, and pointer, allows for direct fixing of the installation structure to the retaining structure when deformation monitoring of deep foundation pit retaining structures is required. The dial on the L-shaped mounting rod is perpendicular to the retaining structure. Therefore, when the retaining structure tilts backward during its support of the deep foundation pit wall, the installation structure, L-shaped mounting rod, and pointer will tilt synchronously. The dial, under gravity, will remain vertical and will not rotate. Personnel can then directly determine the tilt angle of the retaining structure by pointing the pointer to the dial's scale. This facilitates real-time monitoring of the retaining structure's tilt deformation. Thus, this device for monitoring the tilt deformation of retaining structures is simple, compact, and can be quickly installed on the retaining structure, effectively monitoring its tilt deformation. This solves the technical problem of current deep foundation pit retaining structure deformation monitoring devices being inconvenient to install and use. Therefore, this utility model possesses the advantages of simple structure and ease of use.

[0017] 2. The dial of this utility model is divided into a circular plate, a triangular plate, and a counterweight ball. Under the action of the triangular plate and the counterweight ball, a downward force can be applied to the circular plate, so that the dial can always keep its center of gravity facing downward. Therefore, when the mounting structure, the L-shaped mounting rod, and the pointer tilt and deform with the enclosure structure, the dial can always be kept in an automatic vertical state, avoiding the dial from rotating and causing errors in the reading of the tilt and deformation angle of the enclosure structure by the pointer and the dial. This further ensures the accuracy and convenience of the device in monitoring the tilt and deformation of the enclosure structure. Attached Figure Description

[0025] like Figures 1 to 5 As shown, the present invention relates to a deformation monitoring device for deep foundation pit retaining structure, including an installation structure 1, an L-shaped installation rod 2 arranged on the installation structure 1, a scale 3 rotatably arranged at the top L-shaped end of the L-shaped installation rod 2, the scale 3 being parallel to the installation structure 1, and a pointer 4 arranged on the top L-shaped end of the L-shaped installation rod 2, and the pointer 4 corresponding to the scale of the scale 3.

[0026] When deformation monitoring of the retaining structure of a deep foundation pit is required, the mounting structure 1 can be directly fixed to the retaining structure. At this time, the scale 3 on the L-shaped mounting rod 2 of the mounting structure 1 is perpendicular to the retaining structure. Therefore, when the retaining structure tilts backward during the process of supporting the deep foundation pit wall, the mounting structure 1, the L-shaped mounting rod 2, and the pointer 4 will tilt synchronously. The scale 3 will remain vertical due to gravity and will not rotate. At this time, personnel can directly understand the tilt deformation angle of the retaining structure by pointing the pointer 4 to the scale on the scale 3. This allows personnel to understand and monitor the tilt deformation status of the retaining structure at any time. Therefore, the above structure forms a device for monitoring the tilt deformation of the retaining structure. The overall structure is simple and compact, and it can be quickly installed on the retaining structure to achieve the monitoring effect of the tilt deformation of the retaining structure. It is convenient and quick to use.

[0027] Specifically, the mounting structure 1 includes a concave frame 101. Two sets of symmetrical adjusting screws 102 are arranged at the bottom of the concave frame 101. A top fixing plate 103 is arranged at the top of the adjusting screws 102, which penetrate into the interior of the concave frame 101. The adjusting screws 102 are rotatably connected to the top fixing plate 103, and the top of the top fixing plate 103 has anti-slip textures. A mounting plate 104 is arranged on the top of one side of the concave frame 101. A fixing block 105 is arranged at the bottom of the mounting plate 104, and the fixing block 105 is triangular in shape. One side of the fixing block 105 is connected to the concave frame 101. A circular sleeve 106 is arranged at the center of the top of the mounting plate 104, facing away from the concave frame 101. Symmetrical limiting grooves 107 are opened on both sides inside the circular sleeve 106. Limiting protrusions symmetrical to the limiting grooves 107 are arranged on the surface of the L-shaped mounting rod 2. Item 201; A fixing bolt 108 is arranged on the front side of the round sleeve 106, and a fixing screw hole 202 corresponding to the fixing bolt 108 is arranged on the L-shaped mounting rod 2; When installing the installation structure 1, first insert the concave frame 101 into the rod of the enclosure structure, and then turn the adjusting screw 102 to move the top fixing plate 103 upward. At this time, the top fixing plate 103, with its anti-slip texture, can be firmly fixed to the rod of the enclosure structure, thereby realizing the quick installation of the installation structure 1. Then, the L-shaped mounting rod 2 is inserted into the round sleeve 106. At this time, the limiting protrusion 201 on the L-shaped mounting rod 2 is inserted into the corresponding limiting groove 107 in the round sleeve 106. Then, the fixing bolt 108 is screwed into the fixing screw hole 202 of the L-shaped mounting rod 2, thereby realizing the installation of the L-shaped mounting rod 2.

[0028] Furthermore, a transparent protective sleeve 203 is arranged at the L-shaped end of the L-shaped mounting rod 2, and a sealing cap 204 is screwed onto the rear side of the transparent protective sleeve 203. The scale 3 is located inside the transparent protective sleeve 203. The transparent protective sleeve 203, together with the sealing cap 204, can directly seal and protect the scale 3, which can prevent the scale 3 from rotating due to external wind or other factors, and ensure the accuracy of the reading on the scale 3 indicated by the pointer 4.

[0029] In an embodiment of this utility model, the dial 3 includes a disc portion 301, the center of which is rotatably arranged with the L-shaped end of the L-shaped mounting rod 2, the bottom of the disc portion 301 is a triangular plate portion 302, and a counterweight ball 303 is arranged at the bottom of the triangular plate portion 302.

[0030] Under the action of the triangular plate 302 and the counterweight ball 303, a downward force can be applied to the disc 301, so that the dial 3 can always keep its center of gravity facing downward. Therefore, when the mounting structure 1, the L-shaped mounting rod 2 and the pointer 4 tilt and deform with the enclosure structure, the dial 3 can always be kept in an automatic vertical state, avoiding the dial 3 from rotating, which would cause the pointer 4 to read the angle of tilt deformation of the enclosure structure on the dial 3 and thus make errors. This further ensures the accuracy of the device in monitoring the tilt deformation of the enclosure structure.

[0031] Specifically, a connecting screw 304 is arranged at the bottom of the triangular plate part 302, and a connecting screw hole 305 is arranged at the top of the counterweight ball 303, and the connecting screw hole 305 is screwed into the connecting screw 304; the counterweight ball 303 is screwed into the connecting screw 304 through the connecting screw hole 305 to complete the installation, which allows the counterweight ball 303 to be replaced and the size of the counterweight to be adjusted. The greater the weight of the counterweight ball 303, the more stable the dial 3 is at this time.

[0032] Working Principle: This embodiment provides a deep foundation pit retaining structure deformation monitoring device. First, when it is necessary to monitor the deformation of the deep foundation pit retaining structure, the mounting structure 1 can be directly fixed to the retaining structure. At this time, the scale 3 on the L-shaped mounting rod 2 on the mounting structure 1 is perpendicular to the retaining structure. Therefore, when the retaining structure tilts backward during the process of supporting the deep foundation pit wall, the mounting structure 1, the L-shaped mounting rod 2, and the pointer 4 will tilt synchronously. The scale 3 will be in a vertical state under the action of gravity and will not rotate. At this time, personnel can directly understand the tilt deformation angle of the retaining structure by pointing the pointer 4 to the scale on the scale 3. This makes it convenient for personnel to understand and monitor the tilt deformation state of the retaining structure at any time. Therefore, the above structure forms a device for monitoring the tilt deformation of the retaining structure. The overall structure is simple and compact, and it can be quickly installed on the retaining structure to achieve the monitoring effect of the tilt deformation of the retaining structure. It is convenient and quick to use.

[0033] Secondly, under the action of the triangular plate 302 and the counterweight ball 303, a downward force can be applied to the disc 301, so that the dial 3 can always keep its center of gravity facing downward. Therefore, when the mounting structure 1, the L-shaped mounting rod 2 and the pointer 4 tilt and deform with the enclosure structure, the dial 3 can always be kept in an automatic vertical state, avoiding the dial 3 from rotating, which would cause the pointer 4 to read the angle of tilt deformation of the enclosure structure on the dial 3 and thus make errors. This further ensures the accuracy and convenience of the device in monitoring the tilt deformation of the enclosure structure.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
