Problems solved by technology

However, how to fix the displacement gauge in the simulated tunnel has become a stumbling block for many scholars, and there is no related device on the market that can be used directly
Many scholars directly use the method of welding on the pipeline or indirectly measuring the displacement of the soil layer to convert it to the tunn...

Embodiment 1

[0038] Embodiment 1 of the present application provides an indoor model test displacement meter fixing device, including a main structure and ancillary devices, such as Figure 1-7 shown.

[0039] The main structure includes a screw 2 and a fixture, wherein the fixture is mainly composed of a clip 4, a clip seat 5 and a screw socket 6, the clip 4 and the clip seat 5 are welded to form a whole, and the clip seat 5 is provided with a screw socket 6. The clamp and the screw rod 2 are made of inelastic material, which may be metal material, and the length of the screw rod 2 can be freely selected and manufactured according to needs. The clip 4 is made of U-shaped steel sheet, and the U-shaped steel sheet is provided with a card slot, which does not affect the lead-out of the displacement meter signal line while clamping the displacement meter. Screw jack 6 can adopt smooth hole also can adopt threaded hole, as long as can be fastened on the screw rod 2 and get final product.

Embodiment 2

[0043] Embodiment 2 of the present application provides a method for installing an indoor model test displacement gauge fixing device, including the following steps:

[0044] 1) Tunnel model drilling: Before the test starts, holes are drilled at the corresponding positions of the model tunnel according to the test design.

[0045] 2) Fixing of the displacement meter: First, use a pair of displacement meter fixing devices to clamp the ears on both sides of the displacement meter 7 with clips 4, and then tighten the claw fastening screw 3 to fix the displacement meter 7.

[0046] 3) Installation of the displacement meter: Remove the horn nut 1 on the outside of both ends of the screw rod 2, adjust the position of the displacement meter 7, insert the screw rod 2 into the drilled hole from the inside of the tunnel, and screw the horn nut 1 on from the outside of the tunnel , fix the screw rods on both sides on the tunnel wall 8, and then the displacement gauge 7 can be fixed.

Abstract

The invention relates to a laboratory model test displacement meter fixing device, which comprises a screw, a clamp, claw nuts and claw fastening screws, wherein the clamp is mainly composed of a clamping piece, a clamping piece base and a screw insertion hole, the clamping piece and the clamping piece base are welded into a whole, the screw insertion hole is punched in the clamping piece base, the clamping piece is made of a U-shaped steel sheet, a clamping groove is formed in the side face of the U-shaped steel sheet, and the clamping groove is matched with the end part of a displacement meter; the claw nuts penetrate through the two ends of the screw, one end of the screw penetrates through the tunnel wall and is fixed to the tunnel wall through the claw nuts located on the inner side and the outer side of the tunnel wall, and the clamp penetrates through the other end of the screw and is fixed through the claw nuts; and each clamping piece is provided with the claw fastening screwon the side away from the displacement meter. The device has the beneficial effects that the device is composed of the screw and the clamp, the structure is simple, the use is convenient, direct manual screwing can be achieved by adopting the claw nuts and the claw fastening screws, and no external tool is needed.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering in geotechnical and underground engineering, in particular to an indoor model test displacement meter fixing device and an installation method. Background technique [0002] With the development of urban infrastructure construction and the further development of urban underground space, rail transit has become an important part of underground engineering in large cities, and it is showing an increasingly dense trend. It is inevitable that other engineering construction will be carried out in the vicinity of these projects, such as foundation pit excavation, pipeline crossing, etc. The engineering construction will inevitably have an adverse impact on the adjacent tunnels or pipelines, causing deformation of the tunnel, and may cause severe damage. Engineering accidents caused a lot of losses. Therefore, the engineering community has carried out a lot of research on tunnel structure saf...
