Description

Technical Field

[0001] The utility model relates to the technical field of bridge foundation construction, in particular to a safety deformation monitoring device for a cofferdam foundation pit with locking steel pipe piles in a thick muddy soil layer. Background Art

[0002] A cofferdam foundation pit with interlocking steel pipe piles in thick silty soil layers refers to the use of interlocking steel pipe piles to support the foundation pit in silty soil. Interlocking steel pipe piles are a special type of steel pipe with an interlocking function that can be spliced ​​into a deep support structure of a certain length. Before excavating the foundation pit, anchor holes of a certain depth must first be excavated on the ground. Then, interlocking steel pipe piles are pushed into the ground one by one along the anchor holes around the foundation pit, forming a circle of cofferdam structures. This can effectively prevent soil collapse and deformation of the soil around the foundation pit. This type of foundation pit support is often used in areas with soft soil and prone to collapse, such as riverbanks, lakesides, and seaside.

[0003] At present, in order to observe the stability of the cofferdam foundation of the locking steel pipe pile in the thick silty soil layer, a leveling instrument is usually used to judge the deformation of the foundation pit. Since the leveling instrument observation method cannot be fixed on the locking steel pipe, it is impossible to make a timely judgment when the locking steel pipe pile has a certain inclination, which leads to the problem of safety hazards. Therefore, a safety deformation monitoring device for the cofferdam foundation pit of the locking steel pipe pile in the thick silty soil layer is needed to improve the above problems.

A slide slot 203 is provided on the side wall of the mounting block 202, and a sliding block 204 is slidably installed in the slide slot 203. A clamping block 205 is fixedly installed below the side of the sliding block 204 away from the mounting block 202. The top of the inner wall of the slide slot 203 is fixedly installed with a translation slot 206, and the sliding block 204 is fixedly installed at the bottom of the translation slot 206. A transfer block 207 is fixedly installed on the side of the mounting block 202 where the slide slot 203 is provided. The transfer block 207 is "L"-shaped, and a plug-in slot 209 is provided at the end of the folded part of the transfer block 207, and a clamping slot 208 is provided at the bottom of the transfer block 207.

[0026] In this embodiment, refer to Figure 1 and Figure 2 As shown, the clamping block 205 is in an “L” shape, the folded end of the clamping block 205 matches the clamping slot 208 and the auxiliary slot 2011 , and the plugging slot 209 matches the plugging block 2010 .

[0027] In this embodiment, refer to Figure 1 and Figure 3 As shown, the mounting assembly 1 includes a main clamping block 101, a secondary clamping block 102 is rotatably mounted on the side wall of the main clamping block 101, a connecting block 201 is fixedly mounted on the outer wall of the main clamping block 101 close to the secondary clamping block 102, a mounting block 202 is fixedly mounted on the outer wall of the secondary clamping block 102 close to the main clamping block 101, and rubber pads are fixedly mounted on the inner walls of the main clamping block 101 and the secondary clamping block 102 respectively.

[0028] In this embodiment, refer to Figure 1 and Figure 4 As shown, an alarm 4 is fixedly installed on the top of the auxiliary clamping block 102 , and a monitoring component 3 is installed on the side wall of the auxiliary clamping block 102 . The monitoring component 3 includes a connecting block 301 .

[0029] In this embodiment, refer to Figure 1 and Figure 4 As shown, the top of the connecting block 301 is triangular with a rotation groove 302, and the three rotation grooves 302 are respectively rotatably installed with rotation blocks 305, and the three rotation blocks 305 are respectively threadedly connected with threaded rods 306, which extend through the connecting block 301 to the bottom.

[0030] In this embodiment, refer to Figure 1 and Figure 4 As shown, the tops of the three threaded rods 306 are respectively installed with rotating blocks 307, and the three rotating blocks 307 are installed with a level detector 304 for common rotation.

[0031] Working principle: When the device is in use, the main clamping block 101 and the auxiliary clamping block 102 are clamped on the outer wall of the steel pipe mountain back, squeezed and fixed, and the installation block 202 is pressed to move downward. At the same time, the sliding plug-in block 2010 is inserted into the plug-in slot 209, so that the clamping slot 208 and the auxiliary slot 2011 overlap with each other. At this time, the installation block 202 is released. Under the action of the translation slot 206, the installation block 202 will drive the clamping block 205 upward, so that the clamping block 205 and the clamping slot 208 and the auxiliary slot 2011 are clamped and fixed with each other, thereby achieving the benefit of quickly installing the detection device;

[0032] After installation, the level detector 304 is adjusted to a horizontal level by rotating the adjusting block 305 to adjust the threaded rod 306. When the level detector 304 tilts, the sensor inside the level detector 304 will transmit a signal to the control module 303, and the control module 303 will control the alarm 4 to sound an alarm. The benefit of issuing an alarm warning when a certain angle of tilt occurs solves the problem of using the naked eye observation method at the current construction site, which leads to the failure of timely warning and causes safety hazards.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
