Embodiment 1

[0020] A ground subsidence monitoring device for subway tunnel construction, such as figure 1 and 2 As shown, it includes a bracket 1, a drive-in and pull-out component and a monitoring component. The top of the bracket 1 is provided with a drive-in and pull-out component that is driven in and out by rotation, and the lower part of the drive-in and pull-out component is provided with a through A monitoring component for reaction monitoring in a lifting mode.

[0021] Such as figure 1 As shown, the drive-in and pull-out assembly includes a mounting frame 2, a first guide sleeve 3, a helical rack 4, a helical gear 5, and a crank handle 6. The top of the bracket 1 is fixed with the mounting frame 2 through bolts, and the middle part of the mounting frame 2 The first guide sleeve 3 is fixedly connected by bolts, the first guide sleeve 3 is slidingly provided with a helical rack 4, and the rear side of the top of the installation frame 2 is rotatably provided with a helical gear ...

Embodiment 2

[0027] On the basis of Example 1, such as figure 1 and 2 As shown, guide rod 12, lifting plate 13 and second guide sleeve 14 are also included, and guide rod 12 is welded in the middle of the left and right sides of support 1, and guide rod 12 is slidably provided with second guide sleeve 14. Cover 14 is provided with lifting plate 13, and lifting plate 13 is welded with first slide bar 8.

[0028] Such as figure 1 and 2 Shown, also comprise rotating bar 15, bull gear 16, pinion 17, first tooth bar 18, second connecting plate 19 and second tooth bar 20, the rotating type is provided with rotating bar between the lower part of left and right sides of support 1 15. The middle part of the rotating rod 15 is key-connected with a large gear 16 and a pinion 17. The pinion 17 is on the right side of the large gear 16. The front side of the first slide bar 8 is fixedly connected with a first rack 18 by screws. The first rack 18 Engaged with the pinion 17, the lower part of the fro...

Abstract

A ground subsidence monitoring device for subway tunnel construction comprises a support, and a driving-in and pulling-out assembly installed on the support and carrying out driving-in and pulling-outin a rotating mode. Through the driving-in and pulling-out assembly, a monitoring assembly can be rapidly inserted into a required depth, the depth of the monitoring assembly can be accurately controlled, and the practicability of the equipment is improved. The ground subsidence situation can be known by observing the positions of a first sliding rod and a device on the first sliding rod. Becauseof the action amplification effect of a large gear and a small gear, the upward moving height of a second rack is larger, and the ground subsidence situation can be better reflected.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a ground subsidence monitoring device for subway tunnel construction. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway". Many of these systems may be turned into ground or elevated road sections outside the city center in order to match the built environment and consider construction and operating costs. The subway is an urban rail transit system that covers various underground and above-ground right-of-way proprietary, high-density, and high-capacity urban rail transit systems. During the construction of subway tunnels, it is necessary to monitor the settlement of the construction ground at all times. [0003] The patent application publication number is CN11068659A, which discloses a ground settlement monitoring device for sub...
