Problems solved by technology

Due to the large number of monitoring items, different locations of ballast bed measuring points, limited monitoring time and long-distance monitoring range, these instruments installed on tripods are very heavy and repetitive in retracting, moving, positioning, and leveling. Various problems such as continuous measurement, difficulty in positioning, cumbersome leveling, time-consuming and labor-intensive, etc.

Embodiment Construction

[0021] see Figure 1 to Figure 3 As shown, the present invention provides a mobile tripod leveling platform device for subway protection and monitoring, including a self-made tripod 1, a round bubble 2, a strip groove 3, a zigzag groove 4, a telescopic foot screw 5, and a track Wheel 6, bearing plate 7, square reinforced backing plate 8, rail 9 and railing 10.

[0022] Further, the length of the bearing platform 7 is 2.4m, and the width is 1.5m. The first half is designed for erecting the self-made tripod 1, and the second half is designed for the operator to stand on.

[0023] Further, there are three zigzag grooves 4 arranged in regular triangles with a certain depth on the periphery of the front half of the platform plate 7, and the zigzag grooves 4 do not pass through the platform plate 7, and the zigzag grooves 4 can be Fix the rod frame 13 of the self-made tripod 1 so that the zigzag groove 4 will not slide during measurement.

[0024] Further, the self-made tripod 1 i...

Abstract

The invention discloses a mobile tripod leveling bearing platform device and a use method thereof. The device comprises a user-made tripod, a stripy groove, saw tooth grooves, telescopic foot helixes,track wheels and a square bearing platform plate, wherein three saw tooth grooves which do not penetrate through the bearing platform plate are formed in the top surface of the bearing platform plate; the three saw tooth grooves are formed in a regular triangle; the user-made tripod is arranged in the three saw tooth grooves and can be moved leftwards and rightwards; a through hole in which a detection instrument is mounted is formed in the center of the base of the user-made tripod; the stripy groove is flatly formed in the position of a central line of the regular triangle formed by the three saw tooth grooves and penetrates through the bearing platform plate; track wheels contacting a track are arranged close to four corners on the bottom surface of the bearing platform plate; one telescopic foot helix connected with the bearing platform plate is mounted above the cover plate of each track wheel. By adopting the device, the problems that a detection instrument in conventional subway protection monitoring cannot measure continuously and is difficultly arranged in place and great time and labor are acquired in leveling are solved.

Description

technical field [0001] The invention relates to subway protection and monitoring technology, in particular to a mobile tripod leveling platform device applied to subway protection and monitoring, and a method for using the mobile tripod leveling platform device. Background technique [0002] With the development of urban rail transit, the development of commercial and residential buildings along the line is developing towards diversification and three-dimensional development. It is inevitable that post-construction projects will affect the existing tunnels. Underground space, foundation pit project of Shanghai Plaza, etc., either straddle the subway tunnel, or are adjacent to the subway tunnel, among which the impact of deep and large foundation pits on the subway tunnel is the most common. The unloading of the foundation pit excavation will inevitably cause the surrounding strata to move, resulting in changes in the displacement field and stress field of the tunnel, which s...
