Description

Technical Field

[0001] The utility model relates to the field of geotechnical engineering survey, and in particular to a foundation pit monitoring point protection device. Background Art

[0002] Geotechnical engineering investigation is a geological survey and work conducted for various construction projects, such as new construction, renovation and expansion, as well as existing buildings and cultural relics protection projects. The main purpose of this work is to find out the geological conditions of the project site, analyze existing geological problems, and conduct engineering geological evaluation of the construction area. During the geotechnical engineering investigation, foundation pit monitoring points need to be set up on the ground. Foundation pit monitoring points refer to a series of monitoring locations established during the construction of foundation pit projects to monitor and control key factors such as foundation pit deformation, groundwater level changes, and soil displacement. When the foundation pit monitoring points are not in use, protective devices are needed to protect the foundation pit monitoring points to prevent external factors from affecting the foundation pit monitoring points and causing hidden dangers in geotechnical engineering investigations.

[0003] The cam is provided with a plurality of locking plates, the locking plates having the plurality of locking plates being secured to the bottom of the base plate and the plurality of locking plates being secured to the bottom of the base plate.

[0004] During the use of the existing foundation pit monitoring point protection device, since different foundation pit monitoring points have different sizes, and the size of the protection device is basically fixed, when protecting different foundation pit monitoring points, it is necessary to select matching protection devices. Carrying multiple protection devices of different sizes at a time is not only inconvenient to carry, but also the above-mentioned comparative case lacks the means to adjust the size of the foundation pit monitoring point protection device. In this way, when the foundation pit monitoring point protection device is used, multiple protection devices of different sizes not only increase the use cost of the foundation pit monitoring point protection device, but also the large area of ​​geotechnical engineering survey requires frequent replacement of protection devices, which also delays the overall use time.

[0005] Therefore, it is necessary to invent a foundation pit monitoring point protection device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a foundation pit monitoring point protection device, which can freely adjust the size of the protection device to match the size of the current foundation pit monitoring point through a telescopic frame, a fixing knob, a butt joint, a connecting sleeve, a splicing frame, a positioning plate, a positioning screw and an upper enclosure plate. This not only saves the use cost of the foundation pit monitoring point protection device and expands the overall use range, but the free adjustment also makes the device easy to disassemble and carry, avoiding the problem of delaying the overall use time when the area of ​​geotechnical engineering survey is large and the protection device is frequently replaced. At the same time, the positioning plate and the positioning screw also strengthen the connectivity between the device and the ground around the device, so that the device can better protect the foundation pit monitoring point. The effect is to solve the problem that in the prior art, the size of the foundation pit monitoring point protection device is different during use, while the size of the protection device is basically fixed. When protecting different foundation pit monitoring points, it is necessary to select matching protection devices, so that carrying multiple protection devices of different sizes at a time is not only inconvenient to carry, but also the above-mentioned comparative case lacks the means to adjust the size of the foundation pit monitoring point protection device. In this way, when the foundation pit monitoring point protection device is used, multiple protection devices of different sizes not only increase the use cost of the foundation pit monitoring point protection device, but also the large area of ​​geotechnical engineering survey requires frequent replacement of protection devices, which also delays the overall use time.

A connecting sleeve is arranged outside the docking joint. A splicing frame is fixedly installed on one side of the connecting sleeve.

[0009] The positioning plate is arranged on the outside of the telescopic frame and is used to assist in the installation of the positioning screw. A fixing bolt passes through the top of the telescopic frame, one end of the fixing bolt is movably connected to the upper enclosure plate, and a side protection plate is fixedly installed above the upper enclosure plate.

[0010] Preferably, the connecting sleeve is movably connected to the telescopic frame, and the positioning plate and the positioning screw are vertically distributed.

[0014] Preferably, the support rod is movably connected to the fixing sleeve, and the fixing sleeve is symmetrically arranged with respect to the central axis of the side protection plate.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] The utility model is provided with a telescopic frame, a fixing knob, a butt joint, a connecting sleeve, a splicing frame, a positioning plate, a positioning screw and an upper enclosure plate. When the device is used to protect the foundation pit monitoring point, the fixing knob can be twisted to adjust the length of the telescopic frame according to the size of the current foundation pit monitoring point, and then the upper splicing frame can be installed through the butt joint and the connecting sleeve. In this way, the size of the protective device matching the current foundation pit monitoring point can be freely adjusted according to the size of the current foundation pit monitoring point. This not only saves the use cost of the foundation pit monitoring point protection device and expands the overall use range, but the free adjustment also makes the device easy to disassemble and carry, avoiding the problem of large area of ​​geotechnical engineering survey and delaying the overall use time when the protective device is frequently replaced.
