Description

Technical Field

In order to ensure the normal service life and safety of the building, and to provide reliable data and corresponding settlement parameters for future survey, design and construction, it is necessary to monitor it. However, many building settlement monitoring devices are currently unable to be flexibly adjusted during use, and are prone to tilt when used on inclined roads, which in turn affects the monitoring results. Patent documents have been made to improve this.

Beneficial Effects

[0016] The present invention provides a method for monitoring the settlement of a construction engineering foundation. Compared with the existing technology, it has the following beneficial effects: (1) The method for monitoring the settlement of the foundation of a construction project uses a protective locking mechanism and a monitoring extension mechanism in combination. The arrangement of the two mechanisms can fix the entire device by lowering the U-shaped pressure plate when in use, and unlock the L-shaped pull plate frame at the same time. When the unlocked L-shaped pull plate frame is pulled, the monitoring extension mechanism will be extended and opened. When the staff sits on the top of the L-shaped pull plate frame, they can lock the device by pressing to ensure stability during use. At the same time, the monitoring device body can be protected after it is retracted into the protective box body, effectively preventing the equipment from being damaged and extending its service life.

The arrangement of these structures can allow the tooth plate to drive the lifting vertical rod to rise through the gear cylinder when the concave frame is pulled, so that the return-shaped baffle frame and the main body of the monitoring device can rise and be displayed from the inside of the sealing frame, which is convenient for the use of the main body of the monitoring device. At the same time, all structures can be retracted in conjunction with the protective box body to ensure that they can be protected when not in use.

[0018] (3) The method for monitoring the settlement of the foundation of a construction project comprises installing a curved pressure plate inside the L-shaped pull plate frame, and installing a bent abutment plate used in conjunction with the latch plate at the bottom of the curved pressure plate. The arrangement of these structures enables the curved pressure plate to be pressed by the weight of the staff after all the structures are unfolded, so that the bent abutment plate can be pressed against the latch plate, thereby preventing the concave frame and the L-shaped pull plate frame from retracting, thereby ensuring that the entire structure inside the protective box body is locked, making it more stable.

[0019] (4) The method for monitoring the settlement of the foundation of a construction project utilizes the rising of the circular retaining frame to drive the shielding top umbrella and the dust shielding panel to rise together. The shielding top umbrella can be used to shield the workers and equipment, reducing the impact of weather conditions on the equipment and people. The integrated fan can blow air to reduce the heat of the workers, providing comfort for the workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-12 The present invention provides a technical solution: a method for monitoring the settlement of a construction engineering foundation, which specifically comprises the following steps: S1. Fixing the equipment: Use the rectangular cone 122 in the protective locking mechanism 1 to fix the entire equipment to the ground; S2, equipment unlocking: after the fixation is completed, the L-shaped pull plate frame 111 is pulled to unlock the monitoring extension mechanism 2 as a whole; S3, instrument deployment: by pulling the L-shaped pull plate frame 111, the return-shaped baffle frame 207 and the monitoring device body 208 in the monitoring extension mechanism 2 are simultaneously lifted and deployed; S4, structural locking: by pressing the arc surface pressure plate 114, the curved abutment plate 115 locks and limits the entire protection locking mechanism 1 and the monitoring extension mechanism 2; S5. Settlement monitoring: Use the monitoring device body 208 to monitor the building.

[0024] The above-mentioned method for monitoring the settlement of foundation of a construction project is more specifically as follows: S1. Fixing the equipment: Use the wheels at the bottom to push the protection locking mechanism 1 to the position to be monitored, and then rotate the two threaded columns 120 at the same time under the limit of the rectangular plug cone 122, driving the U-shaped pressing plate 121 and itself to descend, and finally insert the rectangular plug cone 122 into the ground to fix the protection locking mechanism 1 as a whole, and at the same time the latch plate 123 will descend and disengage from the plug-in frame 124; S2, equipment unlocking: after the overall fixation of the protective locking mechanism 1 is completed, the L-shaped pull plate frame 111 is pulled by hand to drive the concave frame 108 to move forward under the limit of the sliding guide frame 106 to open the positive pull slot 104. After the concave frame 108 is pulled, the two arc surface portions 109 no longer press the arc bottom block 118. At this time, the storage box 117 is loosened, and then the storage box 117 is pulled outward through the side pull slot 105 and finally limited by the arc bottom block 118. At this time, the equipment is unlocked; S3, instrument deployment: After the concave frame 108 is pulled forward, the gear cylinder 205 is driven to rotate through the meshing of the tooth plate 110 and the tooth plate 206. After the gear cylinder 205 is driven to rotate, it will use the meshing with the tooth block 203 to push the lifting vertical rod 202 to rise inside the tooth block 203. After the lifting vertical rod 202 rises, it will push the return-shaped baffle frame 207 to rise from the inside of the sealing frame 103. At this time, the monitoring device body 208 is outside the protective box body 102. At the same time, after the return-shaped baffle frame 207 rises, it will push the shielding top umbrella 209 to rise together, and use the limit of the vertical rod frame 210 to drive the dust shielding panel 211 to rise to expose the integrated fan 119. At this time, the deployment of the monitoring device body 208 is completed; S4, structural locking: after the L-shaped plate frame 111 is fully opened and the monitoring device body 208 is raised, the user sits on the top of the L-shaped plate frame 111 and the concave frame 108, and the arc pressure plate 114 is pressed down by the body weight and drops into the inside of the L-shaped plate frame 111. When the arc pressure plate 114 drops into the inside of the L-shaped plate frame 111, the curved abutment plate 115 will also drop. After the curved abutment plate 115 drops, it will be located at the latch plate 123 and abut against it. At this time, the L-shaped plate frame 111 will not move anymore, so that the tooth plate 110 will not move at will, ensuring the locking of the gear cylinder 205 so that the lifting vertical rod 202 will not drive the return-shaped baffle frame 207 to drop; S5. Settlement monitoring: After steps S1, S2, S3 and S4 are all completed, the monitoring device body 208 is used to monitor the building foundation. During the monitoring process, the integrated fan 119 will blow air to reduce heat, and the shielding top umbrella 209 will provide shielding to reduce the impact of weather on operations and personnel.
