Embodiment 1

[0016] Example 1: Automatic adjustment and deformation device for steel face dam see figure 1 with figure 2 , a steel truss 3 is set between the dam body 1 and the steel panel 2, and a plurality of deformation adjustments with thrust function are evenly distributed and connected between each fulcrum of the steel truss 3 (where the steel bars meet) and the inner wall of the steel panel 2 device 4. An anchor rod is connected between the steel truss 3 and the dam body 1 .

[0017] see image 3 , the deformation regulating device 4 is an oil pressure jack, the deformation regulating device 4 outside is covered with a spring 5, and one or both ends of the spring 5 are equipped with a pressure sensor 6, and the thrust increase or decrease of the deformation regulating device 4 is controlled by judging that the pressure of the spring 5 increases. It can quickly solve the local deformation problem of the steel face dam. Through the information feedback of the pressure spring 5 and...

Embodiment 2

[0018] Embodiment 2: On the basis of Embodiment 1, a control system is provided, each pressure sensor 6 is connected to the signal input end of the control system, and the output end of the control system drives each corresponding deformation adjustment device 4 . By setting the control system, the pressure sensor 6 can be automatically detected to determine the pressure situation at any position, and the corresponding deformation adjustment device 4 can be adjusted according to the local pressure change, so as to realize the purpose of automatic adjustment.

Embodiment 3

[0019] Embodiment 3: On the basis of Embodiment 1, the deformation adjustment device 4 is changed into an adjustable bolt, and nuts are arranged on both sides of the adjustable bolt. The thread directions of the two nuts are opposite, and the two nuts are respectively welded to the steel panel 2 and the steel structure. On the fulcrum of truss 3. The middle adjustment socket of the adjustable bolt can be easily adjusted by inserting the lever.

Abstract

The invention discloses an automatic adjustment and deformation device for a steel face dam. A truss is arranged between the dam body and the steel face, and a plurality of deformation adjustment devices with thrust function are evenly distributed and connected between each fulcrum of the truss and the inner wall of the steel face. A spring is set on the outer side of the deformation adjustment device, and a pressure sensor is installed at one or both ends of the spring, and the increase or decrease of the thrust of the deformation adjustment device is controlled by judging the increase of the spring pressure. The invention can quickly solve the local deformation problem of the steel face dam, and through the information feedback of the pressure spring and the pressure sensor, the local stress situation can be detected and adjusted in time, and the deformation problem can be solved in the micro-deformation stage, thereby preventing the occurrence of larger deformation . The adjustment method is quick and effective. Maintain the structural inconvenience of the dam body as a whole and prolong the life of the dam body.

Description

technical field [0001] The invention belongs to the technical field of steel face dam support adjustment in water conservancy engineering, and in particular relates to an automatic adjustment and deformation device for a steel face dam. Background technique [0002] The steel face dam uses the steel face as the facing surface of the dam body to prevent the dam body from being deformed or damaged by water erosion and to ensure that the water pressure is evenly transmitted to the side of the dam body. Common steel face dams such as steel face rockfill dam, steel face gravel dam, steel face gravity dam, etc. However, due to the unstable water pressure or the local deformation of the dam body, the local stress on the steel panel will be uneven, resulting in local deformation of the steel panel. If the local deformation of the steel face plate is not dealt with in time, the deformation will be further accelerated, which will eventually affect the safety of the dam body. However...
