In general, when the main structures are buried in the ground during soft ground and excavation work, especially when it is difficult to predict the amount of compression occurring in each layer due to the complicated structure of the layers, a settlement system is installed at the desired point to determine the settlement and speed of the tooth layer. The amount of elasticity and consolidation settlement for each strata is measured.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention includes a floor settling meter 50 which is buried in the ground, and a wire displacement measurement value 100 which electrically detects a mechanical settling amount measured from the floor settling meter 50.

The layered sedimentation system 50 is inserted and protected in the casing 90, as shown in Figs. 1,2,3, is embedded in the ground by an indenter not shown and a head anchor 54 for fixing to the ground layer at the bottom thereof is mounted. The corrugated pipe 52 having a predetermined length is provided, and the corrugated pipe 52 has a plurality of elastic spiders 61A to 66A in an up and down pair for being fixed to each strata while being located in the set strata to be measured. Several settlement elements 61 to 66 are mounted in the form of donuts.

At this time, the reason why the corrugated pipe 52 is used is to enable accurate settlement measurement by increasing friction with the ground layer generated during settlement.

In the present embodiment, the number and spacing of each of the settlement elements 61 to 66 are configured as shown in FIG. 1, but the number of the settlement elements and their spacing are set according to the height of each layer.

One spider connection wire 80 is commonly connected to the spiders 61A to 66A in order to unfold the folded spiders 61A to 66A of the respective settlement elements 61 to 66A.

That is, the spider connection wire 80 initially functions to connect both ends of the tie bands 81 that bind the respective spiders 61A to 66A as shown in FIG. 2, and the corrugated pipe 52 is embedded in the ground. After the spider connection wire 80 is pulled upward, the tie band 81 is released by the elastic restoring force of the spider, and the spider 61A to 66A folded by the elastic force of the spiders 61A to 66A is unfolded. It has a fixed function.

In addition, each of the settlement elements 61 to 66 has a displacement for measuring the settlement behavior of the settlement elements 61 to 66 according to the settlement of individual strata to each displacement measurement sensor 111 to 116, which will be described later. Steel wires 71-76 are connected.

On the other hand, the steel wire displacement measuring device 100 is located on the ground where the layered sedimentation meter 50 is introduced to measure the displacement of the displacement measuring steel wire (71 ~ 76) connected to each settling element of the layered sedimentation system The work table 102 is provided on the ground, and the measuring equipment mounting table 104 is horizontally disposed on the work table 102. (See Fig. 3)

Settlement displacement measurement measuring the displacement of the displacement measuring steel wire according to the settling amount of the sinking elements (61 to 66) is connected to the measuring equipment mounting table 104 corresponding to the several displacement measuring steel wires (71 to 76), respectively. The wire displacement tranceducers 111 to 116 are arranged in the circumferential direction, and the respective displacement measuring sensors 111 to 116 are wound with the respective displacement measuring steel wires 71 to 76, respectively, to the displacement amount of the selected settlement element. The bobbins 111A to 116A which rotate along the same are provided.

In addition, the center of the measuring equipment mounting table 104 is inserted into the sinking elements (61 to 66) in the corrugated pipe (52), the inner for guiding this during the falling behavior of each sinking element (61 to 66) and at the same time to center The rod 82 has an insertion position, and several wires supporting the displacement movement of each displacement measuring steel wire 71 to 76 in the circumferential direction on the side of the measuring equipment mounting table 104 which is the circumference of the inner rod 82. The support rollers 121-126 are rotatably mounted.

At this time, it is preferable that the parts of the present invention are subjected to corrosion treatment in consideration of corrosion by sea water in consideration of the case where it is used in the soil of the coastal area.

The method of using the present settlement measurement system configured as described above will be described.

First, as shown in FIG. 2, the spiders 61A to 66A are tied to the tie band 81 so as to be in close contact with the corrugated pipe 52 side, and then the corrugated pipe 52 is inserted into the casing 90 as shown in FIG. The summer 50 is introduced into the casing 90 of steel and then forcibly embedded in the ground using an intruder (not shown).

Thereafter, the inner rod 82 is inserted into each of the settlement elements 61 to 66 positioned in the corrugated pipe 52 to enable vertical movement of the settlement elements 61 to 66. (See Fig. 5)

Next, as shown in FIG. 6, the casing 90 is pulled up again by an injector (not shown), and the corrugated pipe 52 is left in the ground, and the head anchor 54 under the layered sedimentation system 50 is buried in the ground. The furnace casing 90 is separated.

Then, when the spider connection wire 80 is pulled up to release the tie band 81 that is folding the spiders 61A to 66A, the tie bands 81 are released and each spider 61A to 66A is elastically sequentially from the bottom to the top. Unfolded by resilience, fixed to the strata.

Subsequently, the other end of each displacement measuring steel wire 71 to 76 connected to the sinking elements 61 to 66 is connected to the respective settlement amount displacement measuring sensors 111 to 116 through the wire supporting rollers 121 to 126 corresponding thereto. The dense measurement preparation is completed by connecting the bobbins 111A to 116A with high density.

In this case, when settlement occurs in each strata, the corresponding settlement elements 61 to 66 are selectively settled (in this case, the corrugated pipe is extended), which in turn is a displacement measuring wire connected to each settlement element 61 to 66. The bobbins 111A to 116A selected via 71 to 76 are rotated, and the corresponding settlement displacement measurement sensors 111 to 116 are electrically detected.

Accordingly, each settlement displacement sensor 111 to 116 detects the displacement of the displacement measuring wires 71 to 76, which is preferably transmitted remotely through a transmission device, not shown, and then through a display device (not shown). Have the observer display the measurement information.

According to the present invention configured and operated as described above, it is possible to reduce the inconvenience of having to directly measure the amount of settlement of the strata each time as in the prior art.

In addition, the automatic measurement at a long distance can reduce the time and measurement cost of the system operation, especially the electrical measurement rather than manual measurement, the reliability of the measurement is high.

The minimum measurement unit of the liquid settlement system is 20-30mm, while the present invention has high accuracy as 0.5-1mm.

In addition, the displacement measuring steel wire (71 ~ 76) in the sinking behavior is safely operated in the corrugated pipe (52), and does not damage by freezing and wind even at sea exposure, high durability of the device and less risk of failure.

As described above, according to the present invention, it is possible to easily obtain a reliable and precise measurement value of subsurface subsidence, and to perform remote automatic measurement, which greatly improves the workability of the measurement and has excellent durability.
