Embodiment 1

[0037] like figure 1 , figure 2 As shown, the installation device for the longitudinal water stop belt of the second lining of the tunnel described in this embodiment includes a beam 2, a positioning fixture 1 is movably connected with the beam 2, and fasteners 7 are fixed at both ends of the beam 2 to fasten the beam 2. The device 7 is detachably fixed on the surface of the secondary lining steel bar 5.

[0038] Wherein, the positioning fixture 1 includes at least two "L"-shaped angle steel sheets 13, the two "L"-shaped angle steel sheets 13 are symmetrically arranged, and the top of the angle steel sheet 13 is movably connected with the beam 2. Specifically, the top body of the angle steel sheet 13 is connected by connecting pins. 8 is connected with the beam 2 in rotation, and the free ends of the two angle steel sheets 13 (that is, between the clamping ends are used to place the longitudinal water stop 4); The spacing adjustment member 6 can make the free ends of the an...

Embodiment 2

[0049] see Image 6 As shown, this embodiment further improves the design on the basis of the first embodiment. The difference is that the positioning fixture 1 is movably connected with the positioning fixture 1 through the fine-tuning mechanism 14, and the positioning fixture 1 moves left and right along the length direction of the beam 2 through the fine-tuning mechanism 14. , the position of the positioning fixture 1 is fine-tuned left and right, which further facilitates the alignment of the longitudinal waterstop 4 with the construction joint and facilitates the installation of the longitudinal waterstop 4 .

[0050] The fine-tuning mechanism 14 includes a rectangular installation cavity 146 opened along the length of the beam 2 and a rack 141 installed at the inner bottom of the installation cavity 146. A gear set is engaged with the rack 141, and the gear set is rotatably connected to the top of the positioning fixture 1. Drive the gear set to drive the positioning fix...

Embodiment 3

[0058] Please refer to this Figure 8 As shown, this embodiment further improves the design on the basis of the second embodiment. The difference is that for the convenience of a tunnel secondary lining longitudinal waterstop installation device provided in this embodiment, it can adapt to the secondary lining steel bars 5 with different spacings. , the beam 2 is designed in a telescopic structure, and the telescopic structure includes a rectangular strip-shaped telescopic strip 17 arranged at the end of the beam 2. The telescopic strip 17 can move left and right along the length direction of the beam 2 inside the end of the beam 2, so as to achieve adjustment The length of the beam 2 can be adapted to the secondary lining steel bars 5 with different spacings.

[0059] In order to fix the telescopic strip 17 conveniently, a limit bolt 16 is drilled on the surface of the beam 2, the limit bolt 16 is screwed with the beam 2 through a thread, and the tapping end of the limit bolt...

Abstract

The invention discloses a tunnel secondary lining longitudinal waterstop mounting device and a mounting method thereof, and relates to the technical field of tunnel engineering secondary lining waterproof and drainage construction.The tunnel secondary lining longitudinal waterstop mounting device comprises a cross beam, fasteners and positioning fixtures, the fasteners are fixed to the two ends of the cross beam and detachably fixed to the surfaces of secondary lining steel bars, and the positioning fixtures are fixed to the cross beam. The positioning clamp is movably connected with the cross beam, and the positioning clamp is used for clamping a longitudinal water stop belt; the tunnel secondary lining steel bars are adopted as the waterstop conveying and positioning rails, the longitudinal waterstop can be smoothly installed in the corresponding space position, compared with an end formwork for installing the waterstop, the construction speed is guaranteed, meanwhile, the situation that the waterstop is bent in the installation process can be effectively avoided, and the construction efficiency is improved. And therefore, the integral integrity of the waterstop is ensured.

Description

technical field [0001] The invention belongs to the technical field of waterproof and drainage construction of the secondary lining of tunnel engineering, and particularly relates to an installation device for a longitudinal waterstop of the secondary lining of a tunnel and an installation method thereof. Background technique [0002] With the rapid economic development, my country's transportation construction industry has also made great achievements, especially the tunnel survey and design, construction and operation management levels have been greatly improved. my country's highway construction is still in the peak period of construction, and the number and mileage of highway tunnels are increasing rapidly. Due to the fluidity of water and the transferability of water pressure, the lining structure of the tunnel is often subject to high water head pressure. In the environment of groundwater, any defects and diseases in the lining of the tunnel are very likely to cause le...
