Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, specifically a visual early warning device for deformation and damage of irregularly shaped piles. Background Technology

[0002] Water conservancy and hydropower engineering refers to the engineering and technical field of comprehensively developing and utilizing water resources through the scientific planning, design, construction, and management of water conservancy facilities. Its core objectives include flood control, water supply, irrigation, power generation, navigation, and ecological protection, and it is an important infrastructure supporting socio-economic development and ecological security.

[0003] Irregularly shaped piles (such as X-shaped, H-shaped, bamboo-joint piles, and expanded-base piles) in water conservancy and hydropower projects are widely used due to their high bearing capacity and material efficiency. However, their deformation and failure problems are also quite prominent. The causes of failure involve many factors such as hydrogeology, design, construction and materials. To detect whether irregularly shaped piles (such as X-shaped, Y-shaped, and support piles) are deformed or failed, it is necessary to combine their special cross-sectional shape and stress characteristics and adopt targeted technologies.

[0004] Regarding the cross-sectional characteristics and structural factors of irregularly shaped piles, the asymmetry of the cross-section leads to large differences in stiffness in all directions. For example, L-shaped, T-shaped, and cross-shaped cross-sections have inconsistent stiffness inside and outside the plane. In terms of thin-walled characteristics and stress concentration, irregularly shaped piles are mostly thin-walled components with small cross-sectional curvature and limited bending deformation capacity. In terms of the impact of the construction process, the soil squeezing effect during pile driving will generate additional stress, leading to pile misalignment or bending. In terms of material and load factors, concrete shrinkage and temperature changes will cause deformation, and bending and tension of the pile body under load will also lead to deformation and failure. Therefore, a visual early warning device for the deformation of irregularly shaped piles is needed. However, due to the irregular shape of irregularly shaped piles, the applicability of the early warning device to different pile surfaces is insufficient, and the fixing effect is not good. To address these issues, we propose a visual early warning device for the deformation and failure of irregularly shaped piles. Utility Model Content

[0005] The purpose of this utility model is to provide a visual early warning device for the deformation and damage of irregular piles, so as to solve the problems mentioned in the background art of insufficient visual early warning structure for the deformation of irregular piles and insufficient fixing effect of the early warning device when installed on different piles.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 An embodiment of this utility model is provided: a visual early warning device for deformation and damage of irregular piles, including a display monitor 1, an alarm mechanism 2 inserted inside the display monitor 1, and an installation mechanism 3 provided on the surface of the display monitor 1;

[0026] The warning mechanism 2 includes a temperature measuring cable 210, which is installed at the bottom of the display monitor 1. An alarm light 220 is installed on the surface of the display monitor 1.

[0027] The mounting mechanism 3 includes a first fixing rod 310, which is mounted on the surface of the display monitor 1. A second fixing rod 320 is inserted into the inside of the first fixing rod 310 through a bearing, and a rotating block 330 is fixed on the surface of the second fixing rod 320. A third fixing rod 340 is sleeved on the surface of the second fixing rod 320.

[0028] The bottom end of the temperature measuring cable 210 is pre-embedded inside the irregular pile, and the top end of the temperature measuring cable 210 is installed at the bottom end of the display and monitoring instrument 1. Through the TIP thermal integrity test, the hydration heat effect during the concrete solidification process is utilized to monitor the temperature distribution of the pile body through the pre-embedded temperature measuring cable 210. The abnormal changes in the temperature-depth curve are analyzed to determine the location of defects and the deformation of the pile body outline. Two sets of alarm lights 220 are set, and the two sets of alarm lights 220 are installed at the top and bottom of the display and monitoring instrument 1 respectively. When deformation of the irregular pile is detected, the alarm lights 220 can flash through the electrical signal transmission of the display and monitoring instrument 1 to play a warning role. Alarm lights 220 are set at both the top and bottom to make the warning range of the alarm lights 220 wider.

[0029] The first fixing rod 310 has a sliding groove inside, and the third fixing rod 340 is inserted into the sliding groove. There are two sets of first fixing rods 310. The two sets of first fixing rods 310 are fixed to the surface of the display monitor 1 by bolts. The surface of the second fixing rod 320 is provided with threads, and the interior of the third fixing rod 340 is provided with threaded holes that are compatible with the second fixing rod 320. The second fixing rod 320 and the third fixing rod 340 are threadedly connected. When the second fixing rod 320 rotates, the third fixing rod 340 is inserted into the interior of the first fixing rod 310 to limit the rotation of the third fixing rod 340. This prevents the third fixing rod 340 from rotating, allowing it to move under the rotation of the second fixing rod 320. This adjusts the position of the third fixing rod 340, thereby adjusting the fixing point of the device on the irregular pile.

[0030] The third fixing rod 340 is inserted inside the first fixing rod 310. The interior of the third fixing rod 340 is provided with circular through holes at equal intervals. The fixing bolts can be freely inserted into different circular through holes according to the shape of the irregular pile, so as to achieve stable fixing of the device on the irregular pile, making the device more flexible and more applicable.

[0031] Working principle: When the device is working, the temperature measuring cable 210 is first pre-embedded in the irregular pile, and then the temperature measuring cable 210 is connected to the display monitor 1. The display monitor 1 monitors the irregular pile through the temperature measuring cable 210. When a right deformation is detected, the alarm light 220 will flash to alarm, so that the device can provide a visual early warning of the irregular pile. When it is necessary to fix the device on the irregular pile, according to the shape of the irregular pile, the rotating block 330 is rotated to rotate the second fixing rod 320, so that the third fixing rod 340 moves and fits with the fixing point on the irregular pile. Then, the fixing bolt is passed through the circular through hole on the third fixing rod 340 and inserted into the irregular pile for fixation. The device can adjust the position of the third fixing rod 340 according to the shape of the irregular pile, so that the device can be fixed on irregular piles of different shapes, improving the applicability of the device. The above is the complete working principle of this utility model.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
