Embodiment 1

[0038] refer to figure 1 and figure 2 Shown, a kind of ground stratification subsidence monitoring device of the present invention comprises:

[0039] The settlement pipe 1 is buried vertically in the borehole of the foundation, and a plurality of settlement monitoring units are arranged along the extension direction of the settlement pipe 1, and the settlement monitoring of different positions of the foundation can be realized synchronously through the plurality of settlement monitoring units; the settlement monitoring The unit is set in the settlement tube 1 to ensure that the settlement monitoring unit will not be affected during the working process and ensure long-term stable work;

[0040] The settlement monitoring unit includes: a displacement sensor 2 arranged in the settlement pipe 1, an anchor head monitoring device 4 connected to the displacement sensor 2, the anchor head monitoring device 4 includes an anchor head base 401, and is arranged on an anchor head base 4...

Embodiment 2

[0052] refer to Figure 4 As shown, an assembly method of a foundation layered settlement monitoring device is used to realize the assembly of the above-mentioned foundation layered settlement monitoring device, including the following steps:

[0053] (1) Choose a stainless steel tube, and install a stainless steel metal corrugated hose 3 in the stainless steel tube;

[0054] (2) Install the displacement sensor 2 on the inner wall of the stainless steel pipe, retract the telescopic anchor head 402 in the anchor head monitoring device 4 into the anchor head base 401, and connect the anchor head monitoring device 4 to the displacement sensor 2;

[0055] (3) On the side wall of the stainless steel pipe, a strip-shaped hole is opened at the position corresponding to the telescopic anchor head 402 for the telescopic anchor head 402 to pass through, and the telescopic anchor head 402 can slide in the strip-shaped hole;

[0056] (4) On the side wall of the stainless steel metal corr...

Abstract

The invention relates to a foundation layered settlement monitoring device and an assembly method thereof. The monitoring device comprises a settlement pipe which is vertically buried in a drill hole of a foundation, and is provided with a plurality of settlement monitoring units along the extension direction of the settlement pipe; each settlement monitoring unit comprises a displacement sensor arranged in the settlement pipe and an anchor head monitoring device connected with the displacement sensor; the anchor head monitoring device comprises an anchor head base, a telescopic anchor head arranged in the anchor head base and an anchor head driving source for driving the telescopic anchor head; a strip-shaped hole allowing the telescopic anchor head to penetrate through is formed in the side wall of the settlement pipe; the anchor head driving source drives the telescopic anchor head to penetrate through the strip-shaped hole to be inserted into the foundation; and the telescopic anchor head can move up and down in the strip-shaped hole along with the foundation. According to the assembling method, the laying and using method of the foundation layered settlement monitoring device is provided, the workload of drilling and burying is reduced, in-situ monitoring of different positions is achieved, and the monitoring efficiency and the monitoring precision are improved.

Description

technical field [0001] The invention relates to the technical field of soil settlement monitoring, in particular to a foundation layered settlement monitoring device and an assembly method thereof. Background technique [0002] The deep (layered) settlement of the foundation is mainly observed by embedding settlement markers (deep settlement markers, layered magnetic ring settlement markers) in the foundation soil, of which: [0003] For the burial of deep subsidence marks, it is required to be buried at the required depth of the foundation soil design. The leveling elevation measurement method is used to measure the settlement of subsidence marks at different depths, which is similar to the surface settlement observation method. Multiple burials at different depths are not required. Only one deep subsidence mark can be buried in one hole, and multi-hole burial is required, and the workload is relatively large; [0004] The layered magnetic ring settlement standard can be r...
