Abstract

The invention discloses an in-tunnel fabricated bridge structure and a construction method thereof. The in-tunnel fabricated bridge structure comprises a bridge floor, a mounting mechanism, a damping mechanism and a pouring mechanism. The mounting mechanism is mounted on the bridge floor, the mounting mechanism is used for connecting and mounting a plurality of bridge structures, and the mounting mechanism comprises a prefabricated convex beam and a prefabricated concave beam; according to the bridge structure provided by the scheme, when the bridge structure is used, the inserting rods in the prefabricated convex beams can be inserted into the inserting grooves of the prefabricated concave beams, one end of the bolts moves downwards and penetrates through the inserting holes in the inserting rods till the inserting blocks at the bottoms of the bolts are inserted into the grooves, and rapid connection and installation of a plurality of bridge structure main bodies are completed, and the splicing efficiency of the bridge structure is increased, concrete is poured into the pouring grooves in the tops of the prefabricated concave beams, and the concrete flows into the multiple inserting grooves through the multiple channels formed in the pouring grooves in the prefabricated concave beams so that the inserting rods in the inserting grooves are reinforced after the concrete is coagulated, and the multiple bridge structures are connected more firmly.

Description

technical field

[0001] The invention relates to the technical field of tunnel bridges, in particular to an assembled bridge structure in a tunnel, and in particular to a construction method for an assembled bridge structure in a tunnel. Background technique

[0002] As we all know, a tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. Among them, projects that cross rivers or cross mountains and tunnels require the construction of various bridges and tunnels.

[0003] However, there are still some problems in the existing prefabricated bridge structure in the tunnel:

[0004] 1. There are many assembly and installation processes between the prefabricated bridges in the existing tunnels, and there are many installation structures, resulting in more complicated installation, which makes the efficiency of...

Examples

Embodiment 1

[0046]see Figure 1-Figure 6 , the present invention provides a technical solution:

[0047] An assembled bridge structure in a tunnel and a construction method thereof, comprising: a bridge deck 1, an installation mechanism, a damping mechanism and a watering mechanism.

[0048] Wherein, the installation mechanism is installed on the bridge deck 1, the shock absorbing mechanism is installed on the bottom of the installation mechanism, and the watering mechanism is installed on the installation mechanism.

[0049] Among them, such as Figure 1-Figure 6 As shown, in order to complete the quick connection installation between multiple bridge structure bodies and increase the splicing efficiency of the bridge structure, the bridge installation mechanism is installed on the bridge deck 1. The installation mechanism includes a prefabricated convex beam 2 and a prefabricated concave beam 5. The bridge deck 1 One side of the bridge deck 1 is fixedly connected to the prefabricated c...

Embodiment 2

[0059] see Figure 1-Figure 6 , the present invention also provides a construction method for a prefabricated bridge structure in a tunnel, comprising the following steps:

[0060] S1, the pier column 11 is placed on the installation place of the tunnel bridge, by pouring concrete at the bottom of the pier column 11, the concrete covers the inserting column 27, the first stirrup 26 and the second stirrup 28, and the guide column in the four pillars 12 14 and the movable column 16 are respectively slidably installed inside the second chute 21 and the first chute 20 of the pier column 11, so that the column 12 is installed on the pier column 11;

[0061] S2. After the pillars 12 are installed, install the prefabricated concave beam 5 on the top of two of the pillars 12 and the prefabricated convex beam 2 on the top of the other two pillars 12, and between the prefabricated concave beam 5 and the prefabricated convex beam 2 The bridge deck 1 is installed, and the support frame 1...
