Problems solved by technology

[0004] 1) The cofferdam method has a long construction period, which has a great impact on surrounding traffic and pollutes the water environment. It is difficult to detect the high part of the pier for large piers, and it is only suitable for relatively shallow water flow environments;
[0005] 2) Manual underwater detection relies on divers for underwater detection. Due to the complex environment near the pier, the water flow is fast and the impact force is strong, the safety of divers is difficult to be guaranteed. At the same time, due to the complex surface conditions of the pier, it is difficult to rely on divers to eliminate the surface of the pier. The interference of the environment, but the precise disease condition of the pier cannot be detected;
[0006] 3) The underwater robot detection method mostly relies on the ROV robot to perform optical inspection on the surface of the pier, but the under

Example Embodiment

[0070] Example 1

[0071] like figure 1 A prefabricated bridge full-scale structure detection and conservation platform, including a prefabricated bridge ring ring structure, a mounting frame disposed above the prefabricated bridge grouped, disposed on a hanging device on the upper layer space, a hydraulic pressure of the underlayer space Binduted platform and detection conservation platform.

[0072] like image 3 The preformed bridge rocker includes an upper layer and a lower layer projecting a concrete structure, and the prefabricated concrete structure is complemented in the initial stage of the bridge pier.

[0073] As shown in Fig. 4 (a) - (b), four angular positions of the upper space space of the mounting frame are provided with a hanging device, and an early warning device, a storage device, and a positioning storage device are provided.

[0074] The hanging device includes a roller and a height sensor that is secured by a cable and a connector of the detection conservatio...

Example Embodiment

[0093] Example 2

[0094] like figure 2 This embodiment is based on the maintenance work based on the platform. The staff determines whether the bridge pier needs to be maintained according to the test results of the pier.

[0095] After the detection work is completed, the staff determines whether the pier needs to be maintained, when needed, the staff performs the detection of the maintenance platform on the hydraulic ballast platform and the disassembly and assembly of the maintenance operation unit. When the switching of the detection operation device and the maintenance operation device, the staff disassembles the drive motor, the transmission chain, and the pair detecting device of the detecting operation device, and the maintenance operation device is respectively used after the dismantling is completed. The structure, external structure, and safety guard are mounted inside the drive rail, and then the first part, the second portion is connected again, then the staff leaves...

Example Embodiment

[0103] Example 3

[0104] In this embodiment, the upper layer platform of the mounting frame is provided with an early warning device, a storage device, and a positioning storage device. The early warning device includes an infrared sensor, alarm signal, and alarm.

[0105] The infrared sensor transmits infrared rays to the surrounding water, detects the speed and location information of the vessel in the nearby waters, and transmits the acquired vessel speed and location information to the positioning storage device, and determines whether the ship can be safely passing the vessel safely through the bridge. It is guaranteed that the vessel is secured at the waters of the bridge at a safe speed. When it is judged that the vessel is dangerous at risk or the vessel has a risk of colliding with the pier, the warning light will make red light, and the alarm will make a prompt voice, and a sound-light warning reminder for the corresponding vessel.

[0106] The positioning storage devic...

Abstract

The invention discloses a prefabricated pier omni-directional structure detection and maintenance platform which comprises a prefabricated pier surrounding structure used for being matched with a prefabricated pier, wherein a carrying frame is arranged above the prefabricated pier surrounding structure, a lifting device is arranged in the upper-layer space of the carrying frame, and a hydraulic ballast platform and a detection and maintenance platform are arranged in the lower-layer space of the carrying frame; the detection and maintenance platform is located below the hydraulic ballast platform in the working period and ballasts the hydraulic ballast platform in the non-working period; the detection and maintenance platform is connected with a hoisting device and moves in the vertical direction of the pier under the action of the hoisting device; the detection and maintenance platform is arranged on the outer side of the pier in a sleeving mode and internally provided with an annular structure, and the detection and maintenance platform is connected with the detection device in the detection working period or connected with the maintenance device in the maintenance working period; and the detection device and the maintenance device are placed on the hydraulic ballast platform in respective non-working periods.

Description

technical field [0001] The invention relates to the field of bridge pier safety protection, in particular to a prefabricated bridge pier all-round structure detection and maintenance platform. Background technique [0002] In recent decades, with the rapid development of national infrastructure, the total number of domestic bridge piers has exceeded one million, and the number of bridges has continued to grow. However, most bridge piers have a long service life, and bridge safety problems have become increasingly serious. At present, bridge pier detection mostly relies on the cofferdam method, artificial underwater detection, and underwater robot detection. These detection methods are complex, costly, and lack targeted repair of pier damage. [0003] At present, there are the following disadvantages in existing detection methods: [0004] 1) The cofferdam method has a long construction period, which has a great impact on surrounding traffic and pollutes the water environmen...
