Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a foundation pit slope detection device for construction engineering. Background Art

[0002] With the acceleration of urbanization, high-rise buildings and underground projects are increasing. As the basic part of these projects, the safety and stability of foundation pits are directly related to the quality of the entire project and the safety of personnel. Foundation pit projects involve many factors, such as geological conditions, surrounding environment, construction technology, etc., and the actual situation during the construction process often deviates from the design assumptions, so strict monitoring is required.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN20565291U discloses a foundation pit slope detection device for construction engineering. The device is pulled vertically downward by a traction rope, and the traction rope cooperates with the scale line on the measuring plate to detect the slope of the foundation pit. The current device relies on the staff to manually read the scale line data on the measuring plate, which means that the data acquisition is intermittent rather than continuous. In the case where the foundation pit deformation may occur rapidly, this intermittent data acquisition method may not be able to capture the key deformation information in time. In order to capture the possibility of extreme slopes for prevention, we propose a foundation pit slope detection device for construction engineering. Utility Model Content

They are existing public technical means in this field and will not be described in detail here. A humidity sensor 301 is fixedly connected to the outer wall of the protective shell 3, and the humidity sensor 301 penetrates the base plate 1. The protective shell 3 is fixedly connected to an observation window 4.

A dehumidification component 7 is provided on the surface of the observation window 4, and the scale display device 5 includes a limit rod 51.

[0032] In the embodiment of the utility model, in order to accurately capture the extreme slope, the staff can obtain the change of the slope of the foundation pit in real time and avoid the risk of safety accidents. Specifically, the observation window 4 is arranged on one side of the inner wall of the protective shell 3 and is fixedly connected to the limit rod 51. The limit rod 51 is connected to the counterweight block 52 through the sleeved traction rope. Through the movement of the protective shell 3, the movement of the sleeved traction rope drives the movement of the counterweight block 52 to measure the slope. The inner wall of the observation window 4 is provided with a limit groove 56, and the limit block 55 is clamped in the limit groove 56. The limit block 55 is fixedly connected to the rotating shaft 53, and the rotating shaft 53 is fixedly connected to the flip plate 54. The observation window 4 adjusts the internal components through the opened movable groove 402, and the traction rope cooperates with the scale line 401 on the observation window 4, so that the slope of the foundation pit can be detected. The reset device 6 includes an adjusting rod 61, and the adjusting rod 61 penetrates the protective The shell 3 is arranged in the movable groove 402, and the adjusting rod 61 is pressed to adjust the clamping angle of the adjusting rod 61 in the movable groove 402. The inner wall of the observation window 4 is rotatably connected with a rotating ring 62, and a triangular groove 621 is provided on the surface of the rotating ring 62. The triangular groove 621 is clamped with the adjusting rod 61. When the adjusting rod 61 starts to be adjusted, the clamping part thereon will drive the triangular groove 621 to move together. Since the triangular groove 621 is provided on the rotating ring 62, the rotating ring 62 will also rotate accordingly. The rotating ring 62 is rotatably connected with a clamping plate 63, and the clamping plate 63 is clamped with a clamping block 64, and the clamping block 64 is fixedly connected to the outer wall of the pushing plate 65. The pushing plate 65 is slidably connected in the arc groove 66 provided on the inner wall of the observation window 4. The movement of the rotating ring 62 drives the hinged movement of the clamping plate 63. The movement of the clamping plate 63 drives the clamped pushing plate 65 to be pushed forward. The pushing plate 65 slides to the top of the arc groove 66 to reset the flip plate 54.

[0033] Furthermore, in order to improve the resistance of the slope detection device in the foundation pit environment and improve the use effect of the subsequent slope detection device, specifically, the dehumidification component 7 includes a bamboo fiber film 71, the outer wall of the protective shell 3 is paved with the bamboo fiber film 71, and the bamboo fiber film 71 is fixedly connected with a connecting plate 72, and the connecting plate 72 is hinged in the positioning groove 73 opened by the adjusting rod 61. After pressing for card connection and positioning, the adjusting rod 61 drives the hinged connecting plate 72 to extend and open during the sliding process, and unfolds the rolled bamboo fiber film 71. Bamboo fiber is a natural cellulose extracted from bamboo, with extremely high moisture absorption capacity, ranking first among the five natural fibers, and 3 to 5 times that of ordinary cotton fiber.

After placement, the observation window 4 on the protective shell is observed. Through the movement of the protective shell 3, the movement of the sleeved traction rope drives the movement of the counterweight block 52 to measure the slope. During the measurement, the movement of the counterweight block 52 will squeeze the rotating limit block 55, and the limit block 55 rotates in the limit groove 56 to adjust the angle. Through the rotation angle of the limit block 55, the flipping angle of the flip plate 54 can be clearly observed, so as to read the slope of the foundation pit.

After the measurement is completed, the adjusting rod 61 is pressed to adjust the clamping angle of the adjusting rod 61 in the movable groove 402. The adjusting rod 61 starts to adjust, and the clamping part thereon will drive the triangular groove 621 to move together. Since the triangular groove 621 is provided on the rotating ring 62, the rotating ring 6 2 will also rotate accordingly, the movement of the rotating ring 62 drives the hinged movement of the card plate 63, and the movement of the card plate 63 drives the connected push plate 65 to push forward, and the push plate 65 slides to the top of the arc groove 66 to reset the flip plate 54, which can not only accurately capture the extreme slope, so that the staff can obtain the change of the foundation pit slope in real time to avoid the risk of safety accidents, but also facilitate the reset of the scale display device 5 for repeated use. After pressing for clamping and positioning, the adjustment rod 61 drives the hinged connecting plate 72 to extend and open during the downward movement, and unfolds the rolled bamboo fiber film 71. Bamboo fiber is natural cellulose extracted from bamboo, with extremely high moisture absorption capacity, ranking first among the five natural fibers, which is 3 to 5 times that of ordinary cotton fiber. It contains a special ultra-fine pore structure with a strong capillary effect, can instantly absorb moisture, and can keep the protective shell 3 dry for a long time in a humid environment, thereby improving the resistance of the slope detection device in the foundation pit environment and improving the use effect of the subsequent slope detection device.
