Description

Underwater pier detection device

Technical Field

The utility model relates to a detect technical field under water, particularly, relate to a pier detection device under water.

Background

After the underwater bridge is built, the bridge pier is below the water surface for a long time, the using state of the structure is difficult to observe, check and test visually, and the bridge usually needs to be maintained regularly, particularly the appearance of the underwater part is detected: whether the crack and the cavity are eroded or not needs to be checked whether the overall dimension is deformed or not, and meanwhile, the strength of the concrete needs to be measured.

The existing underwater bridge pier detection technology mainly comprises the following two operation methods:

1. the operation method of the combined underwater camera detector comprises the following steps: the combined underwater camera detector is composed of an underwater camera, an underwater illuminator, a transmission cable, a monitor, a dubbing system, a special hoisting device (used as a vertical moving device of a camera lens) and a barge (used as a working platform). During detection, the rope for the workboat is fixed with the detected abutment, and each shooting point is marked on the water surface above the foundation. A camera is fixed on the initial origin of a part to be detected by adopting special hoisting equipment, vertical shooting is carried out, the distance between the lens and the surface of a target object (based on the fact that the target object can be seen clearly) is required to be kept about 20-30 cm in the shooting process, and the camera can move stably and uniformly as much as possible. After finishing one vertical shooting, the shooting is continued in a translation mode along the base surface or in a reverse mode around a specified interval. During the shooting process, a record and a description are made. The operation method of the combined underwater camera detector has the advantages of high detection speed, low cost and safer operation of detection personnel, and has the defect of higher requirement on the detected environment, namely, the detection effect is better only in the environment that the water quality is relatively clear, no microbes such as aquatic weeds and the like are attached to the surface of the foundation and the depth of the part of the foundation in water is not more than 5 m. Therefore, the method is more suitable for detecting the bridge foundation with small span in mountainous area bridges and plain areas, but not for detecting the foundation of large-span bridges and sea-crossing bridges in plain areas.

2. Provided is a diving detection operation method. During detection, a diver holds an underwater camera with a lighting device to dive, carries a small magnet, a scraper knife, a steel ruler, a water diversion positioning lead rope and a searchlight, and is matched with a real-time monitoring video system to obtain image data of an underwater structure, and the diver is in real-time communication with a water surface monitoring person to ensure the quality of a shot image and all details of the defects of the structure and the response capability of encountering an emergency. The detection range of the operation method is as follows: the pier water surface reaches the position of the river bed. Moving route: from the water line, the underwater structure is roughly divided into a plurality of areas with the depth range according to the range of the pitching visual angle (about 1.5 m) within 60 cm from the base of the diver, and in each depth area, the diver inspects and photographs the base surface of the depth area by 360 degrees, so that the disease condition of the structure under water is completely reflected. And then carrying out disease localization: if a disease is found at a certain position, a diver judges the depth of the disease according to a depth meter or a carried scale, releases a buoy at the position, and water surface personnel roughly judge the direction of the buoy relative to a foundation according to preset coordinates and water flow influence, determines the specific position of the disease by combining the depth, marks the corresponding position on a water level line of an upright post, records the pile number, the height, the radial position and the video file number of the disease on recording paper, and draws a disease direction schematic diagram. And finally, screenshot and video recording: 2-3 pictures are taken for the disease-free piles; besides normal screenshot on the basis of the disease, screenshot on the disease part from different angles, and the picture can completely reflect the type of the disease and the severity of the disease.

In the prior art, the operation mode of the combined underwater camera is only suitable for still water areas and clear water areas, and the areas with turbid water quality or large water flow velocity are often poor in performance. The underwater operation mode of personnel is that the personnel can not operate underwater for a long time, and can not accurately position the flaw detection position, and the requirement on the professional technology of the operating personnel is high, and the personnel often have great risks in dangerous water areas.
