Problems solved by technology
If the experimental research is carried out directly on the actual project, it will be time-consuming and huge
[0003] At present, there are still very few experimental devices for studying the interaction of ice-water-pillars in low-temperature environments, and most of the remaining ones are large-scale experimental devices. The cost of construction and testing is very high, and it is difficult to be widely used in existing actual projects. Verification of ice load test and safety assessment of bridges

Embodiment 1
[0026] combine Figure 1-5 As shown, the devices and functions of the device are introduced, and the water tank 1 provides the test environment. The horizontal motion support 2 and the motion track 3 provide a motion carrier, and the front sliding beam 4 and the rear sliding beam 5 make the motion more stable and regular. A pressure sensor 8 and a laser rangefinder 15 are used to test the ice-pillar interaction. Two motion rails 3 are installed in parallel on the water tank 1, and the horizontal motion bracket 2 is horizontally placed and installed on the motion rail 3. The front sliding beam 4 and the rear sliding beam 5 sliding beams are arranged on both sides of the horizontal motion bracket 2, which are connected with the front and rear The rollers connected by the sliding beam are located in the groove of the moving track 3, and the horizontal moving support 2 is supported on the moving track 3 by the front sliding beam 4 and the rear sliding beam 5. The reaction beam 6...

The invention discloses an ice-water-pier column interaction test device. The device comprises symmetrically-arranged motion rails installed on the two sides of the top of a water tank, a horizontal motion support is connected to the motion rails in a sliding mode, a front sliding beam is arranged at the front end of the horizontal motion support, a rear sliding beam is arranged at the rear end ofthe horizontal motion support, and the two sides of the front sliding beam and the rear sliding beam are connected with rolling wheels through steel plates. A joint is fixed at one end of the horizontal motion support, the joint is connected with one end of a horizontal loading screw rod through a built-in bearing, and the other end of the horizontal loading screw rod penetrates through a counter-force beam to be connected with a motor. The lower portion of the test pier column extends into water and an ice layer of the water tank, the top of the test pier column is connected with a horizontal movement support through a connecting fastener, and a pressure sensor is arranged between the horizontal movement support and the middle of the test pier column. The device has lower operation requirements on each mechanical structure, is convenient for observing the fracture and crushing process of the ice layer and the structural response of the pier stud, and provides a simple and effective technical scheme for the ice-resistant test research of the bridge in the cold region.
Description
technical field [0001] The invention belongs to the comprehensive field of bridges, water conservancy and cold region engineering, and in particular relates to an ice-water-pier interaction test device. Background technique [0002] For a long time, the water surfaces of a large number of reservoirs, oceans, rivers, and lakes in northern my country tend to freeze and form ice sheets in winter. The deformation of the ice layer and the action of drift ice will cause deformation or damage to the bridges on it, threatening its safety. With the continuous development of my country's transportation and water conservancy, the transportation network has gradually extended to high latitude and high altitude regions, and there are more and more bridges in alpine regions. Subsequently, a large number of deformations and local damages of bridges under ice loads in cold regions may cause huge losses of life and property and adverse social impacts. Therefore, the ice-resistant performan...
