Embodiment 1

[0043] Such as Figure 1-4As shown, a bridge deck structure with adjustable deck elevation includes a bridge deck roof system 1, an adjustable truss support system 2, a bridge deck bottom plate system 3, and a bridge deck side plate 20; the bridge deck roof system 1 includes several Bridge deck trusses 4 arranged at certain intervals in the longitudinal direction of the bridge, several bridge deck purlins 5 arranged above the bridge deck trusses 4 along the longitudinal direction of the bridge and connected to two adjacent trusses 4 , and bridge deck steel plates 6 arranged above the bridge deck purlins 5 The adjustable truss support system 2 includes a truss support vertical bar 7, a threaded support sleeve 8 on the inside, and a support bottom plate 10 with a screw rod 9; the bridge deck bottom plate system includes a shaped steel mesh 11 composed of shaped steel 19; The bridge deck side plate 20 is a steel plate, the upper edge is connected with the bridge deck steel plate ...

Embodiment 2

[0068] Different from Embodiment 1, in this embodiment, a bridge deck structure with adjustable deck elevation is applied to the Pinkuan Bridge project. The solution of this embodiment will be described in more detail below with a more specific example.

[0069] Such as Figure 5-6 As shown, in a city road upgrading and reconstruction project, a new Pinkuan bridge was built on the side of the original old bridge. The bridge width of the old bridge was 11.85m, and that of the Pinkuan bridge was 4.6m. The design vehicle load level is city-A level, and the design safety level is level one. The newly built Pinkuan Bridge adopts a bridge deck structure with adjustable deck elevation to adjust the deck elevation, which mainly includes the following steps:

[0070] Step 1. The factory assembles a bridge deck structure with adjustable deck elevation; it includes a bridge deck roof system 1, an adjustable truss support system 2, and a bridge deck floor system 3; the bridge deck roof ...

Abstract

The invention discloses a bridge floor structure capable of adjusting a bridge floor elevation. The bridge floor structure comprises a bridge floor top plate system, an adjustable truss support system, a bridge floor bottom plate system and bridge floor side plates. The bridge floor top plate system can be integrally lifted, the adjustable truss support system is used for supporting the bridge floor top plate system and can vertically adjust the height of the bridge floor top plate system, the adjustable truss support system is arranged on the bridge floor bottom plate system, and the bridge floor side plates seal the peripheries of the bridge floor top plate system, the adjustable truss support system and the bridge floor bottom plate system. The invention further discloses a bridge floor elevation adjusting method. The method has the advantages of light jacking or hoisting weight, convenience in construction, high construction safety coefficient and the like, and has good economical efficiency. And the elevation of the bridge floor can be flexibly adjusted and can be high or low, so that the application range is wider. And the bridge floor elevation is very simple to adjust, and the construction progress is fast. The requirements of economic development in China on traffic transportation can be better met.

Description

technical field [0001] The invention relates to a bridge deck structure and a bridge deck elevation adjustment method, in particular to a bridge deck structure with adjustable bridge deck elevation and a bridge deck elevation adjustment method, belonging to the technical fields of highway engineering and municipal engineering. Background technique [0002] With the rapid development of transportation and the increasing number of highways and municipal constructions, the connection between bridges, subgrades, and tunnels, and the connection between the new bridge and the old bridge in the Pinkuan Bridge project have also gradually received attention. Due to the uneven settlement of the foundation and the additional compression of the backfill soil on the back of the abutment, after a period of use, the bridge has a sudden change in height at the connection with the road behind the abutment, the tunnel and the old bridge of Pinkuan Bridge, resulting in jumping This phenomenon ...
