Problems solved by technology

This method of separate construction is not only time-consuming and labor-intensive, but also requires pile foundations to be constructed separately in the riverbed, resulting in a waste of building materials and an increase in construction costs. Obviously, the coordinated construction of road bridges and road tunnels will achieve better results. effect, but there are no related bridge-tunnel collaborative construction cases in this field for reference, and those skilled in the art urgently need a construction method for bridge-tunnel collaborative construction

Embodiment

[0032] Example: such as figure 1 , 2 , 3, and 4, the present embodiment specifically relates to a beamless construction method of a bridge-tunnel collaborative construction structure, and the beamless construction method mainly includes the following steps:

[0033] (1) At the beginning of the dry season, set up a diversion open channel on the upstream side of the river to divert the river, and renovate the river according to the planned section 12 of the riverbed; the bridge 2 to be constructed and the tunnel 1 to be constructed are obliquely intersected in the river area , and across the riverbed 12, the tunnel 1 is located under the main girder 11 of the bridge 2, the tunnel 1 is a double-hole box culvert structure, the tunnel 1 and the bridge 2 are constructed at the same time, and the stress and deformation are coordinated;

[0034] A circle of foundation pit enclosure structure is set in the river channel area to be constructed, and tunnel uplift piles 3, bridge piles 4...

Abstract

The invention discloses a beamless construction method for a bridge-tunnel collaborative building structure, which comprises the following steps of: carrying out slope excavation on a foundation pit, and correspondingly chiseling away a bridge pile head and a tunnel uplift pile head in a tunnel coverage area after excavating to a designed depth of a tunnel bottom plate; a bottom plate, side walls and a middle partition wall of the tunnel are constructed on the upper portions of the bridge piles and the tunnel uplift piles; then, a tunnel top plate reinforcement cage and a rib plate reinforcement cage are bound, and a rib plate type bridge abutment integrated with the tunnel top plate is formed through synchronous pouring; bridge pile heads on the two sides of the tunnel coverage area are chiseled away, and a straight wall type bridge abutment is constructed; and a bridge girder is erected above the straight wall type bridge abutment and the rib plate type bridge abutment. The structure has the advantages that the bridge lower structure and the tunnel top plate are integrated, the structure force transmission route is clear, meanwhile, construction can be more efficient, the construction period is shortened, and the manufacturing cost is saved; the bridge superstructure is also used as an anti-floating weight of the tunnel, the tunnel is used as a part of a bridge foundation to assist in transferring the load of the superstructure, and displacement control of the two parts is facilitated.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a beamless construction method for a bridge-tunnel collaborative construction structure. Background technique [0002] In the construction of urban municipal transportation, road bridges and road tunnels are common construction projects. For the construction of the two across the river, the conventional practice is to cross the river in the form of bridges on the surface roads, and build tunnels on the side of the bridges to form a composite traffic system. This method of separate construction is not only time-consuming and labor-intensive, but also requires pile foundations to be constructed separately in the riverbed, resulting in a waste of building materials and an increase in construction costs. Obviously, the coordinated construction of road bridges and road tunnels will achieve better results. However, there are no relevant bridge-tunnel collaborat...
