Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering, and in particular relates to a side wall deflection monitoring mechanism which is convenient for use on a steel cofferdam. Background Art

[0002] A steel cofferdam is a temporary hydraulic device commonly used in bridge construction. It is used to guide and control water flow during bridge construction. It is usually made of steel plates or other materials and encloses an enclosed area to prevent water flow from interfering with construction. The installation and removal of steel cofferdams are relatively fast and can be adjusted and moved as needed to adapt to different construction environments.

[0003] In the above, since the steel cofferdam needs to be dismantled after the construction period is completed, in daily construction situations, the cofferdam can be used as a solid line of defense to resist water flow. In order to enhance the resistance strength of the cofferdam, symmetrical triangular inner supports are usually used to achieve combined reinforcement. In order to flexibly obtain the deflection data of the inner side of the cofferdam after assembly and splicing, we need to indirectly complete the cofferdam deflection measurement by detecting the support data of the triangular inner supports to avoid interfering with the normal use of the cofferdam.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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 making creative efforts shall fall within the scope of protection of the present invention.

[0021] The embodiment of the present utility model provides a side wall deflection monitoring mechanism that is convenient for use on a steel cofferdam, including a base mechanism 100; for example, Figure 1-Figure 2 shown.

[0022] The base structure 100 includes a base 101, and the base 101 is equipped with a surrounding structure 200 and a supporting structure 300. The surrounding structure 200 includes a purlin plate 201 fixedly connected to the upper surface of the base 101, and the side of the purlin plate 201 is plugged and connected with a docking block 202, and the side of the docking block 202 is adapted and installed with an adaptation groove 203, and the inner side surface of the purlin plate 201 is snap-connected with a bevel angle brace 301, and the outer surface of the bevel angle brace 301 is fixedly connected with a detector 303, and the end face of the detector 303 is plugged and connected with a lead 304.

[0023] The surrounding mechanism 200 also includes a reinforcement 204, which includes a vertical support plate 204a fixedly connected to the top of the surrounding purlin plate 201, and the side of the vertical support plate 204a is plugged into a side plate 204b, and the lower surface of the side plate 204b cooperates with the surrounding purlin plate 201.

[0024] A limiting hole 205 is provided on the side of the bottom of the purlin plate 201 , and a steel pipe column 103 is plugged and connected to the inner side of the limiting hole 205 .

[0025] Specifically, through the cooperation of the base mechanism 100, the surrounding mechanism 200 and the supporting mechanism 300, the process effect of assembling the steel cofferdam is basically achieved. The plug-in arrangement of the purlin plate 201, the docking block 202 and the adapter groove 203 allows more purlin plates 201 to be combined and spliced, so that the flow isolation range of the purlin plate 201 is significantly expanded, which is conducive to more stable engineering construction. The snap connection between the inclined angle brace 301 and the purlin plate 201 makes the adjacent purlin plates 201 have a better supporting effect, strengthens the structural strength of the purlin plate 201, and reduces the deformation of the purlin plate 201 after being impacted by water flow. The fixed connection between the detector 303 and the inclined angle brace 301, The detector 303 can directly detect deformation data, and through the connection between the inclined angle support 301 and the purlin board 201, the deflection data of the purlin board 201 is indirectly obtained, which plays a positive role in the subsequent replacement and maintenance of the purlin board 201. The plug-in connection between the vertical support plate 204a and the side plate 204b enables the purlin board 201 to ensure normal function when resisting the impact of water flow, and also allows the top of the purlin board 201 (the part that is less susceptible to water flow impact) to remain stable, reducing the interference of the side deflection data detection. The plug-in connection between the limit hole 205 and the steel pipe column 103 allows the purlin board 201 to obtain basic protection function on the side during assembly.

[0026] The number of the steel pipe columns 103 is several; for example, Figure 2-Figure 3 shown.

[0027] The sides of several of the steel pipe columns 103 are connected by snap-fitting with engaging blocks 104 , and the engaging blocks 104 are all integrally formed special-shaped blocks.

[0028] The upper surface of the support platform 101 is fixedly connected to an internal base 206, the center of the internal base 206 is consistent with the center of the support platform 101, and the bottom of the support platform 101 is adapted to be installed with bottom piles 102, and the bottom piles 102 are symmetrically distributed at the corners of the support platform 101.

[0029] Specifically, the snap-fit ​​connection between the interlocking block 104 and the steel pipe column 103 allows the steel pipe columns 103 to be connected in series in a row, further improving the basic side protection effect, while also protecting the construction effect of the internal base 206. The bottom piles 102 are symmetrically distributed at the bottom of the pedestal 101, which allows the pedestal 101 to be evenly stressed, ensuring the stability of the pedestal 101.

[0030] The number of the bevel gussets 301 is several; for example, Figure 3-Figure 4 shown.

[0031] A plurality of the beveled angle supports 301 are symmetrically arranged on the purlin plate 201 , and flanges 302 are fixedly sleeved on the sides of the beveled angle supports 301 .

[0032] The purlin plates 201 are arranged in a parallel combination, and the purlin plates 201 are all made of integrally formed steel.

[0033] Specifically, the symmetrical arrangement of the bevel angle braces 301 on the purlin board 201 can make the supporting effect of the purlin board 201 more uniform, and also provide more detection points for the deflection measurement of the purlin board 201, thereby improving the accuracy of the deflection data.

[0034] Working principle: First, the steel pipe column 103 is spliced ​​and installed with the base 101 through the limiting hole 205. Then, the purlin plate 201 is installed in series through the docking block 202 and the adapter groove 203 to block the impact of water flow. After the side plate 204b and the vertical support plate 204a are plugged and installed, they are stably fixed on the top of the purlin plate 201 to stabilize the top of the purlin plate 201.

[0035] When the purlin plate 201 is deformed due to excessive impact of water flow, the flange 302 is fixedly sleeved on the outer surface of the bevel angle brace 301, and the detector 303 and the lead 304 are plugged and installed. Then, by detecting the support data of the bevel angle brace 301 and comparing it with the previous support data, a series of data calculations are performed to obtain the deformation of the purlin plate 201 (i.e., deflection data), and finally the specific usage of the purlin plate 201 is reported.
