Condensation joint cutting and sealing integrated device for bridge deck concrete

Abstract

The invention discloses a bridge deck concrete contraction joint cutting and sealing integrated device which structurally comprises a contraction joint cutting and sealing device, decks and piers. Thecontraction joint cutting and sealing device is provided with a scale size adjusting descending device, a vehicle body, a sealing leveling device and a sealant introducing device. The bridge deck concrete contraction joint cutting and sealing integrated device has the beneficial effects that through the contraction joint cutting and sealing device, the strength of concrete at the deck position can be detected via a concrete strength detector inside equipment, then a contraction joint is cut by the scale size adjusting descending device, and thus a concrete crack can be guided to be generatedalong a cut joint, and random cracks are prevented; then the contraction joint is filled with materials through a rail forwarding glue filling device in the sealant introducing device, after materialfilling, the sealing leveling device can be arranged on a groove moving rail to walk so as to conduct leveling through a leveling unit, and cutting, injecting and leveling are integrally achieved through the contraction joint cutting and sealing device.

Description

technical field [0001] The invention relates to a shrinkage joint cutting and sealing integrated device for bridge deck concrete, which belongs to the field of bridge construction. Background technique [0002] A bridge is a building that vehicles and pedestrians can safely pass through in existing life, and bridge construction is a professional construction Concrete is the most important pouring material for building bridges. Bridges are made of concrete. Currently The disadvantages of technology sharing are as follows: [0003] During the setting and hardening of concrete, the cement hydration will release a large amount of heat, which will cause the temperature of the concrete to rise. After the cement hydration reaction is over, the temperature of the concrete begins to drop. During the cooling process, the concrete has solidified and hardened, and the temperature drops The shrinkage of the concrete will cause the concrete to crack, and the direction of the cra...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an integrated device for shrinkage joint cutting and sealing of bridge deck concrete, so as to solve the problem that cement hydration will release a large amount of heat during the concrete setting and hardening process, which will cause the temperature of the concrete to rise and greatly Part of the cement hydration reaction ends, and the concrete temperature begins to drop. During the cooling process, the concrete has solidified and hardened. The shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relatively random, which seriously affects the quality and service life of the pavement. The cracks will cause rainwater to enter Inside the roadbed, it will speed up the damage of the bridge
