Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction reinforcement technology, specifically relating to a reinforcement trolley for cast-in-place partition walls in shield tunnels. Background Technology

[0002] The tunnel substructure adopts a precast box culvert and cast-in-place reinforced concrete backfilling structure. The part above the box culvert uses a 30cm composite secondary lining. A central partition wall (30cm thick) is set between the two tunnel tracks, with a flue slab on top and an emergency evacuation platform in the middle of the central partition wall. After the shield tunnel section is completed, the construction of the cast-in-place central partition wall begins. The construction of the central partition wall is carried out in two stages: the first stage is the construction of 1m high concrete, and the second stage is the construction up to the bottom of the flue slab. The reinforcement of the central partition wall is tied and formed on site inside the tunnel. The base formwork uses steel formwork. Steel formwork is heavy and not easy to fix, which poses construction risks such as falling objects, falling from height, mechanical injury, and lifting injury. It is necessary to design a reinforcement trolley for the cast-in-place partition wall of the shield tunnel to solve the above technical problems. Utility Model Content

[0005] This utility model embodiment provides a reinforcement trolley for cast-in-place partition walls in shield tunnels, including a gantry trolley and a triangular trolley located on both sides of the partition wall (30); the right side plate (5) of the gantry trolley is fixed to the right side of the secondary lining (2) of the tunnel by two first screws (8); the left side plate (6) of the gantry trolley is connected to the bottom and middle of the first vertical plate (10) by two second screws (11); the first demolding oil rod (9) on the top plate (7) of the gantry trolley is connected to the upper part of the first vertical plate (10); the first vertical plate (10) is fixedly connected to the right side steel template (28) by bolts;

[0006] The triangular frame trolley includes a base (13), a second demolding slat (14), a bottom crossbeam (17), a top crossbeam (26), an inclined side plate (18), a second vertical plate (19), and a left steel template (29). The bottom crossbeam (17) is connected to the upper slide of the base (13) by two support columns (15). The telescopic end of the second demolding slat (14) is connected to the upper slide of the base (13) to enable the bottom crossbeam (17) to move left and right along the slide. The inclined side plate (18) and the second vertical plate (19) are respectively connected to the bottom crossbeam (17) and the top crossbeam (26). The second vertical plate (19) is connected to the left steel template (29) by bolts.

[0007] When the partition wall (30) is in the working state, the first vertical plate (10), the right steel template (28), the second vertical plate (19) and the left steel template (29) are fixedly connected by three sets of third screws (12); when the partition wall (30) is formed in the demolding state, the first demolding oil rod (9) and the second demolding oil rod (14) respectively separate the right steel template (28) and the left steel template (29) from the partition wall (30).

[0008] In one optional embodiment of this utility model, the top of the precast box culvert (1) is provided with a slide rail corresponding to the pulleys at the bottom of the gantry trolley and the triangular frame trolley, and the pulleys can move along the slide rail.

[0010] In one optional embodiment of this utility model, a counterweight (20) is fixed between two clamping members (32) on the surface of the bottom crossbeam (17).

[0011] In one optional embodiment of this utility model, a telescopic rod (16) is provided at the end of the bottom crossbeam (17). When the partition wall is cast in place in the working state, the bottom of the telescopic rod (16) is fixed to the top of the precast box culvert (1) in the tunnel.

[0012] Beneficial Effects: This utility model embodiment provides a reinforcing trolley for cast-in-place partition walls in shield tunnels, including a gantry-type trolley and a triangular trolley located on both sides of the partition wall. The first vertical plate of the gantry-type trolley is fixedly connected to the right-side steel template by bolts, and the second vertical plate of the triangular trolley is connected to the left-side steel template by bolts. When the partition wall is being cast in place during operation, the first vertical plate, the right-side steel template, the second vertical plate, and the left-side steel template are fixedly connected by three sets of third bolts. After the partition wall is formed in the demolding state, the first and second demolding hydraulic rods separate the right-side and left-side steel templates from the partition wall, respectively. This reinforcing trolley solves the problem of fixing the steel templates during cast-in-place partition wall construction, improving the construction efficiency and safety of the partition wall.

The left side plate 6 of the gantry trolley is connected to the bottom and middle of the first vertical plate 10 by two second screws 11. The first demolding oil rod 9 on the top plate 7 of the gantry trolley is connected to the upper part of the first vertical plate 10. The first vertical plate 10 is fixedly connected to the right side steel template 28 by bolts.

[0022] Figure 4 Combination Figure 1 The triangular frame trolley includes a base 13, a second demolding slab 14, a bottom crossbeam 17, a top crossbeam 26, an inclined side plate 18, a second vertical plate 19, and a left steel template 29. The bottom crossbeam 17 is connected to the upper slide of the base 13 by two support columns 15. The telescopic end of the second demolding slab 14 is connected to the upper slide of the base 13 to enable the bottom crossbeam 17 to move left and right along the slide. The inclined side plate 18 and the second vertical plate 19 are respectively connected to the bottom crossbeam 17 and the top crossbeam 26. The second vertical plate 19 is connected to the left steel template 29 by bolts.

[0023] like Figure 1 As shown, when the partition wall is in the working state and cast-in-place, the first vertical plate 10, the right side steel formwork 28, the second vertical plate 19, and the left side steel formwork 29 are fixedly connected by three sets of third bolts 12. Figure 2 As shown, after the partition wall is formed in the demolded state, the first demolding oil gun 9 and the second demolding oil gun 14 respectively separate the right side steel template 28 and the left side steel template 29 from the partition wall 30.

[0024] like Figure 5 As shown, the top of the precast box culvert 1 is equipped with slide rails 4 corresponding to the pulleys at the bottom of the gantry trolley and the triangular frame trolley, allowing the pulleys to move along the slide rails. For example, the bottom pulley 5-1 of the right side plate 5 of the gantry trolley moves along one slide rail 4. The bottom pulley of the left side plate 6 of the gantry trolley moves along another slide rail 4. The two pulleys at the bottom of the base 13 move along two other slide rails 4.

[0025] like Figure 1 and Figure 4As shown, a first reinforcing rib 21, a second reinforcing rib 22, a fourth reinforcing rib 24, and a fifth reinforcing rib 25 are connected between the inclined side plate 18 and the second vertical plate 19.
