Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and more specifically, relates to a deep foundation pit construction monitoring system at a construction site. Background Art

[0002] A deep foundation pit refers to an excavation depth exceeding 5 meters (inclusive), or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment, and underground pipelines. During the construction of a deep foundation pit, scientific instruments, equipment, and methods are required to comprehensively monitor the displacement, tilt, settlement, stress, cracking, basement uplift, dynamic changes in groundwater levels, and pore water pressure of the supporting structure and the surrounding environment (soil, buildings, roads, underground facilities, etc.).

[0003] Existing monitoring systems often use inclination sensors to monitor the sidewalls of deep foundation pits. However, over extended periods of use, these sensors can become depleted, leading to interruptions in monitoring. This presents limitations. In light of these limitations, this paper investigates and improves existing structures and shortcomings, aiming to provide a deep foundation pit construction monitoring system for construction sites with the goal of achieving greater practical value.

[0027] The connecting mechanism includes a connecting rod 9 that is slidably connected to the inner side of the connecting column 3. A pyramid 10 is fixedly installed on one end of the connecting rod 9 to reduce the resistance encountered by the connecting rod 9 when the connecting rod 9 is inserted into the side wall of the deep foundation pit.

[0028] Among them, two groups of blocks 11 are symmetrically and slidably connected on the inner side of the connecting rod 9, and two groups of openings for the blocks 11 to pass through are respectively provided on both sides of the connecting rod 9 corresponding to the two groups of blocks 11. The block 11 is provided with a sloped surface 1 on the side extending out of the opening and away from the connecting column 3, and is provided with a sloped surface 2 on the side located on the inner side of the connecting rod 9 and close to the connecting column 3. The two groups of sloped surfaces 2 are jointly slidably connected with a top block 12 to increase the stability of the connecting rod 9 when it is fixed; a limit plate 15 is fixedly installed on the inner side of the connecting rod 9, which is arranged to resist the two groups of blocks 11, to prevent the top block 12 from moving excessively and causing the block 11 to fall off.

[0029] Among them, dovetail blocks are fixedly installed on both sides of the top block 12, and dovetail grooves are provided on one side of the two groups of clamping blocks 11 corresponding to the dovetail blocks. The dovetail grooves are slidably connected to the dovetail blocks. When the connecting rod 9 needs to be disassembled, the two groups of clamping blocks 11 can be driven to retract into the inner side of the connecting rod 9.

[0030] Among them, a stud 13 is rotatably connected to the inner side of one end of the connecting rod 9, and a threaded barrel 14 is threadedly connected to the outer side of the stud 13.

[0031] Among them, a through slot is provided on one side of the main frame 1, and a pointer 16 is fixedly installed on one side of the sliding seat 6. A slide groove is provided on the top side of the through slot, and multiple groups of sliders 17 are slidably connected to the inner side of the slide groove corresponding to the pointer 16.

[0033] The two groups of connecting rods 9 are both fixedly mounted with a limiting seat 21 on one end away from the pyramid 10 to prevent the connecting rods 9 from falling off the connecting column 3 .

[0034] The working principle of this embodiment is as follows: when it is necessary to monitor the deep foundation pit, first fix the main frame 1 and the base 20 to the ground with expansion screws, then fit the connecting column 3 with the side wall of the deep foundation pit, insert the connecting rod 9 into the side wall of the deep foundation pit until the limit seat 21 is tightly fitted with the connecting column 3, and then rotate the stud 13 to drive the threaded cylinder 14 and the top block 12 to move, and drive the two sets of blocks 11 to move to the outside of the connecting rod 9 to complete the installation of the main frame 1. When the side wall of the deep foundation pit tilts, the connecting column 3 will follow the tilt and drive the sliding seat 6 to move through the connecting rod 5 and the connecting seat 7. The inclination angle of the side wall of the deep foundation pit is judged by the moving distance of the sliding seat 6.
