Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, a construction equipment for the second lining of the vault of the anchor chamber of the suspension bridge tunnel, including a trolley 1, a stand 2, a moving track 3, a traction unit, and a construction formwork 11, the construction formwork 11 is connected to the outside of the trolley 1, The trolley 1, the platform 2 and the traction unit are connected in sequence, and the trolley 1 and the platform 2 are both connected on the moving track 3.

[0026] Pull the platform 2 to the position of the pre-construction vault through the traction unit, install the waterproof board and steel bars, and pull the trolley 1 to this position after completion. After the trolley 1 is in place, lift the trolley 1 and the construction formwork 11 to the top The installation position of the construction formwork, adjust the construction formwork 11, confirm that it is consistent with the design position, and then use a backing plate to pad the bot...

Embodiment 2

[0028] On the basis of Embodiment 1, the traction unit includes a tractor 5, a traction wire rope 6 steering wheel 12, and the stand 2, the steering wheel 12 and the traction machine 5 are sequentially connected by the traction wire rope 6; the traction machine 5 is a traction hoist Or chain hoists. The tractor 5 is arranged on the portal frame of the tunnel anchor hole or the tunnel anchor hole. The number of the tractor 5 can be adjusted according to the actual situation. Compared with chain hoists, traction hoists have faster traction speed and stable construction; chain hoists have relatively simple equipment, which can be selected according to actual conditions and have strong adaptability.

[0029] The trolley 1 also includes a shifter 4 through which the trolley 1 is connected to the moving track 3 . The shifter 4 is convenient for the trolley 1 to slide on the moving track, reduces friction, saves time and effort, and improves work efficiency.

[0030] Such as Figu...

Embodiment 3

[0032] On the basis of Embodiment 2, hangers 7 are also included. The number of hangers 7 is 2 groups and the left and right sides of the 2 groups of hangers 7 are symmetrically distributed on the left side wall and the right side wall of the front anchor room. The axis direction of the front anchor chamber is connected with the moving track 3 . The number of hangers is determined according to the force calculation results of the trolley construction. In this project, there are 6 hangers in 2 groups under the trolley, 3 hangers on each side, symmetrically distributed from left to right; the moving track 3 is a sliding track, and the sliding track adopts The channel steel is made and placed on the hanger 7 of the left side wall and the right side wall of the front anchor room. Ensure that the sliding track and the hanger are all in close contact to facilitate the movement of the trolley.

[0033] Also include a jack 8, the bottom of the jack 8 is connected to the top of the ha...

Abstract

The invention belongs to the technical field of bridge construction equipment, and particularly provides suspension bridge tunnel anchor chamber vault secondary lining construction equipment and method. The suspension bridge tunnel anchor chamber vault secondary lining construction equipment comprises a trolley, a rack, a moving rail, a traction unit and a construction formwork, wherein the construction formwork is connected to the outer side of the trolley, and the trolley, the rack and the traction unit are sequentially connected; the problems that when an existing tunnel anchor front anchorchamber secondary lining vault is constructed, the work amount of scaffold erection is large, a full framing and a front anchor chamber arc vault support are in an unstable state, stress is prone todeviating during concrete pouring, unbalance loading of the full framing is caused, the control difficulty in the construction process is large, and the construction cost is high are solved. The equipment has the advantages of being simple in structure, convenient to use, safe in construction and capable of meeting construction requirements.

Description

technical field [0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a second lining construction equipment and method for an anchor chamber vault of a suspension bridge tunnel. Background technique [0002] In the construction of the second lining of the tunnel-type anchorage chamber of the suspension bridge, because the anchorage tunnel is an inclined structure and the slope of the tunnel is relatively large, it is impossible to use a large lining trolley for the second lining of the tunnel. According to past experience, the second lining of the anchor chamber in front of the tunnel anchorage is usually poured with a full scaffolding support formwork system. Since the anchoring system has been completed during the construction of the second lining of the front anchor chamber, and the distance between the main cable strands at the anchor point is small, the scaffolding must pass through the main cable when erecti...
