Description

Technical Field

[0001] The present invention relates to the technical field, and specifically relates to an integrated maintenance monitoring system and a maintenance monitoring method for bridge piers. Background Art

[0002] In bridge engineering, the construction material often used is concrete. During the construction, the early strength of the concrete needs to reach a certain target, and the curing of the concrete is particularly important. At present, in order to ensure the concrete strength, the common curing inspection methods for bridge piers are as follows:

[0003] 1) Using a crane to lift, and personnel stand in the hanging bucket to wind the film along the pier for curing. However, this method has great potential safety hazards;

[0004] 2) Placing a drip water tank on the pier and curing by the drip irrigation method. This method requires frequent replacement of the drip water tank using a crane, increasing the curing cost;

[0005] 3) Using bridge pier spray curing machinery and equipment. This method has a high cost and the water evaporates relatively quickly, requiring multiple curing operations;

[0006] 4) Using a rebound and core drilling sampling device to monitor the concrete strength. Core drilling sampling damages the main body, the rebound error is relatively large, and it is easily affected by external factors. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an integrated maintenance monitoring system and a maintenance monitoring method for bridge piers.

[0008] The technical solution adopted by the present invention to solve its technical problems is: an integrated maintenance monitoring system for bridge piers, including: a film winding device, a drip irrigation curing device, a water supply device, and a concrete strength monitoring device; wherein,

[0009] The film winding device is used to wind the film around the outer periphery of the bridge pier with the assistance of a crane, and specifically includes a connecting rod, and rolling pulleys are detachably installed at both ends of the connecting rod. A hanging ring is arranged at the outer end of the central roller shaft of each rolling pulley;

[0010] The drip irrigation curing device is used to perform drip irrigation curing on the bridge pier, and specifically includes a tank body, a water inlet is arranged at the upper part of the tank body, and drip irrigation ports are uniformly arranged along the axial direction at the lower part of the tank body;

[0011] The water supply device is used to supplement water source to the tank body;

[0012] The concrete strength monitoring device is used for real-time detection of the concrete strength of bridge piers, and specifically includes a sensor, a data processing module, and a wireless communication module. The sensor continuously detects the temperature during the concrete solidification process. The data processing module determines the strength detection result by establishing a maturity curve based on the temperature using the maturity method. The wireless communication module uploads the strength detection result to the remote monitoring platform.

[0013] Optionally, the water supply device includes a water tank, a controller, a storage battery, a solar panel, and a water pump. The water pump is placed inside the water tank, and the water outlet of the water pump is connected to the water inlet of the tank body through a water pipe. The controller is electrically connected to the storage battery, the solar panel, and the water pump.

[0014] The present invention also discloses a maintenance monitoring method for bridge piers, which is used for the above-mentioned integrated maintenance monitoring system, and includes:

[0015] Before the concrete pouring of the bridge pier, the concrete strength monitoring device is embedded inside the pier. The wireless communication module establishes communication with the remote monitoring platform, and basic information indicating the pier number and pouring date is established through the remote monitoring platform.

[0016] After the pier is poured, a roll of plastic film is sleeved on the connecting rod. Rolling pulleys are installed at both ends of the connecting rod. The hanging ring on one of the rolling pulleys is hung on the crane hook, and the hanging ring on the other rolling pulley is connected to a pulling rope.

[0017] The crane hoists the film winding device to the top of the pier. After the end of the plastic film is fixed to the top of the pier, the worker pulls the pulling rope on the ground and walks around the pier. At the same time, the crane cooperates with the worker's movement and slowly lowers the film winding device until the plastic film is wound around the outer circumference of the pier.

[0018] The sensor continuously detects the temperature during the concrete solidification process. The data processing module determines the strength detection result by establishing a maturity curve based on the temperature using the maturity method. The wireless communication module uploads the strength detection result to the remote monitoring platform. The worker can understand the concrete strength of the pier in real time through the strength detection result displayed on the remote monitoring platform.

[0019] The tank body is hoisted to the top surface of the pier. The water supply device is connected to the water inlet on the tank body through a water pipe. The water supply device regularly injects water into the tank body, and the water in the tank body falls to the pier through the drip irrigation port to complete drip irrigation maintenance.

[0020] The present invention adopting the above technical solution, compared with the prior art, has the outstanding features: 1. It can ensure the curing time; 2. It reduces the labor cost; 3. It reduces the crane mechanical cost; 4. It reduces the waste of water resources; 5. It can reduce the electricity cost and does not require connecting cables; 6. Compared with rebound and core drilling sampling, it belongs to an accurate non-destructive testing method. Description of the Drawings
