Design and Construction of Bridge Implantable Bridge Continuous Device
Abstract Damage to expansion joints of bridges can cause the phenomenon of vehicle jumping. The phenomenon of bridge-head jumping is one of the common problems in the construction of roads and bridges, and it is also a major problem that plagues the industry. This article describes the design and construction technology of the implanted bridge deck continuous device, and aims to provide a reference for solving the bridgehead trip.
The telescoping device of the bridge will significantly reduce the ride comfort, and the telescopic device itself and the structures in its vicinity are prone to damage. In addition, the noise and vibration that accompany the maintenance of telescopic equipment can cause troubles in bridge management. The solution to this problem is to remove the telescopic device and set up a seamless device that allows the road surface to be continuous, that is, the deck is seamless.
Bridge decks are divided into four major categories: continuous main girders, continuous decks, continuous beams, and continuous decks.

In the actual project, the continuous economy and construction of the bridge deck are more feasible, so the application is more extensive. The bridge deck will be continuously introduced below. 13785855258 pay
Since the deformation generated at the continuous surface of the bridge deck is mainly absorbed by the paving material and the paving material does not absorb the large deformation performance, this method is applicable to the existing bridges with shorter beam lengths and lower beam heights. In particular, pre-stressed and reinforced concrete bridges with shorter beam lengths have smaller retracting capacity and less deformation at the ends of the beam, making it suitable for continuous bridge decks.
There are four types of deformation in the stretching position:
1) The telescopic deformation caused by the temperature change of the main beam;
2) Rotational deformation at the end of the main beam caused by the strain caused by the live load;
3) Deformation caused by wheel load acting directly on the telescopic position;
4) Deformation due to drying shrinkage and creep of the main beam.
The function of the continuous absorption and deformation of bridge decks is:
1) Telescopic absorption type;
2) telescopic dispersion type;
3) Flexibility inducing type.
