Description

Displacement vector monitoring is one of the key monitoring items in slope monitoring. Currently, the displacement monitoring method on the market mainly uses GNSS equipment designed by Beidou positioning technology. This monitoring method has high cost, especially for large-scale slopes, the cost is often in the millions, and considering economic applicability, it cannot be widely laid out, and it is basically single-point monitoring, which leads to narrow monitoring and missed early warning.

For slope protection structures such as lattice beams, arched skeletons, and soil and rock bodies inside the lattice beams, it is difficult to take into account due to topographic problems, and thus effective control of the stability of the entire slope body cannot be achieved.

The universal measuring devices 6 are installed at the top of the columns 5 arranged on the top 1 and platform 2. The specific measuring devices 7 are installed at the top of the columns 5 arranged on the foot 3.

[0033] The slope where the embodiment of the present application is located is a three-stage slope, and three monitoring sections are provided. The measuring device at the three slope feet 3 of each section is a specific type measuring device 7, and the universal type measuring device 6 is installed at the top of the remaining first-stage platform, the top of the second-stage platform and the top of the slope 1. The cable fixing pier 8 is installed behind the measuring point at the top of the slope 1, and the flexible cable 4 of each monitoring section is fixed at the pier. At the same time, the control cable 11 is anchored on the slope surface protection structure or rock mass near the flexible cable 4 of each monitoring section and is fixed with the main cable. It should be noted that the fixing point 10 of the control cable 11 and the main cable needs to be anchored in the direction of the top of the slope 1 in the form of a hanging body (if the fixing point is lower, it will be in the form of a drag towards the slope feet 3, which cannot achieve the monitoring purpose, and at the same time, it will affect the monitoring effect of the upper-stage platforms due to the fixed form of the main cable).

[0034] As shown in Figure 2 , the universal type measuring device 6 includes an encoded counting pulley 61, an angle measuring device 63, a lifting ruler 62 and a universal network module. The counting pulley 61 is used to measure the slope displacement data of the stand column 5. The lifting ruler 62 is used to measure the settlement data of the stand column 5. The angle measuring device 63 is used to measure the rotation angle data of the stand column 5 in the horizontal plane. The universal type measuring device 6 further includes a universal protection box 64. The counting pulley 61 is installed in the universal protection box 64. The universal protection box 64 is provided with perforations on both sides for the flexible cable 4 to pass through. The angle measuring device 63 and the lifting ruler 62 are both in the form of a cylinder. The lifting ruler 62 is installed in the angle measuring device 63.

[0037] The flexible cable 4 is fixed on the cable fixing post 8 of the slope top 1 and passes through the counting pulley 61 of each universal measuring device 6 and the counting pulley 71 of the special measuring device 7 at the slope foot 3. The counting pulley 71 of the special measuring device 7 applies force to the flange wheel 72 to keep the flexible cable 4 tight while the installation of the flexible cable 4 is completed. The flexible cable 4 further comprises a control knot 11 for setting a fixed knot 10 on the flexible cable 4 above the slope structure; the control knot 11 is connected to the fixed knot 10 and the anchor point respectively by setting the anchor point on the slope structure on both sides of the flexible cable 4. The universal network module is used to send the code and the number of rotations of the counting pulley 61 of the universal measuring device 6, the settlement data and the angle data to the designated receiving terminal.

[0038] The special network module is used to send the code and the number of rotations of the counting pulley 71 of the special measuring device 7 to the designated receiving terminal. According to all the data obtained by the slope monitoring device, the current working condition of the slope can be determined by manual or machine, and a warning can be given.

[0039] The slope monitoring device has several measuring lines, and each measuring line is arranged along the slope direction, i.e. the measuring lines are parallel to each other.

[0040] The five working conditions can be warned by using the embodiment of the present application.

[0041] Working condition 1:

[0042] When the slope top 1 slides but the first and second platforms do not slide, there are three cases: ① the cable fixing pier 8 of the slope top 1 does not slide, the third platform rock-soil body and the third slope surface protection structure all slide, at this time, the recording pulley 61 of the universal measuring device 6 of the slope top 1 is displaced, at the same time, the recording pulley of the universal measuring device 6 of the first platform and the special measuring device 7 of the slope foot 3 all only have the recording pulley rotate and the rotation values are completely the same, the recording pulley 61 of the second platform has the same value change as the recording pulley 61 of the first platform and the recording pulley 71 of the slope foot 3, if the slope top 1 collapses not along the slope direction, the angle measuring device 63 of the slope top 1 and the second platform rotates and the directions are the same. The settlement data (the lifting scale 62 is stretched) of the lifting scale 62 proves that the slope body is in settlement, if the angle measuring device 63 data is unchanged, it proves that the slope slides along the slope direction, otherwise, the third slope body sliding direction can be judged according to the rotation value of the angle measuring device 63; ② the cable fixing pier 8 of the slope top 1 and the third platform rock-soil body remain stable but the third slope surface protection structure fails and slides down, at this time, the recording pulley 61 of the universal measuring device 6 of the slope top 1 has no value change, but the lifting scale 62 of the slope top 1 produces the data change (the lifting scale 62 is lowered) and the lifting scale 62 of the first and second platforms has the data change but the amplitude is smaller than that of the slope top 1, if the protection structure does not slide along the slope direction, the angle measuring device 63 of the slope top 1 and the second platform all rotate and the rotation directions are opposite; ③ the cable fixing pier 8 of the slope top 1, the third platform rock-soil body and the third slope surface protection structure all slide, at this time, the biggest feature is that the special measuring device 7 at the slope foot 3 is driven by the flange wheel disc 72 to recover the flexible cable 4 to make it slide and displace, at the same time, the recording pulley 61 of the universal measuring device 6 of the first and second platforms synchronously produces the same displacement data.

[0043] Working condition 2:

[0044] When the slope top 1 and the second platform are stable but the first platform slides, there are two cases: ① the rock-soil body of the general platform slides and the slope surface protection structure partially fails and slides down, at this time, the recording pulley 61 and the lifting scale 62 of the universal measuring device 6 of the first platform measuring device all change, the lifting scale 62 produces the settlement data (the lifting scale 62 is stretched), at the same time, the recording pulley 61 of the universal measuring device 6 of the second and third platforms has no value change, only the lifting scale 62 of the second platform measuring device has the data change (the lifting scale 62 is lowered), the change amplitude is affected by the settlement amplitude of the first platform, if the angle measuring device 63 data is unchanged, it proves that the slope slides along the slope direction, otherwise, the first slope body sliding direction can be judged according to the rotation value of the angle measuring device 63; ② when the rock-soil body of the first platform remains stable but the first slope surface protection structure fails and slides down, at this time, the recording pulley 61 of the universal measuring device 6 of the first to third platforms has no value change, but the lifting scale 62 will produce the data change (the lifting scale 62 is lowered), if the protection structure does not slide along the slope direction, the angle measuring device 63 of the first platform measuring device rotates.

[0045] Case 3:

[0046] When the slope top 1 and the first level platform are stable but the second level platform slips, there are two cases: ① When the general platform rock-soil body slips, the slope surface protection structure partially fails and slides down, at this time, the counting pulley 61 of the second level platform universal measuring device 6 slips, at the same time, the counting pulleys 61 of the first level platform and the slope foot 3 rotate and the rotation values are completely the same, the counting pulley 61 of the slope top 1 has no value change, if the second level platform collapses not along the slope direction, the angle measuring device 63 of the first level platform and the slope top 1 rotates and the rotation directions are opposite. The lifting scale 62 produces subsidence data (the lifting scale 62 stretches) to prove that the slope body is subsiding, if the angle measuring device 63 data is unchanged, it proves that the slope is sliding along the slope direction; ② When the second level platform rock-soil body remains stable but the second level slope surface protection structure fails and slides down, at this time, the counting pulleys 61 of the first to third level platforms have no value change, but the lifting scale 62 produces downward data (the lifting scale 62 descends), if the protection structure is not sliding along the slope direction, the angle measuring devices 63 of the first and second level platforms will rotate and the rotation directions are opposite.

[0047] Case 4:

[0048] When the slope top 1 is stable but the first and second level platforms slip, if the adjacent two or more levels of slope surfaces of the same slope slip at the same time, generally the protection structures of the adjacent sliding slope surfaces have failed at this time, there is only one case, the counting pulley 61 of the first and second level platform universal measuring device 6 slips, the lifting scale 62 produces subsidence data (the lifting scale 62 stretches), the counting pulley 61 of the slope top 1 has no value change, but the lifting scale 62 produces downward data (the lifting scale 62 descends), if the first and second level platforms do not slip along the slope direction, the angle measuring device 63 of the slope top 1 will rotate.

[0049] Case 5:

[0050] When the three measuring platforms slip, there are two cases: ① When the fixed pier of the slope top 1 does not slip, at this time, the counting pulleys 61 and the lifting scales 62 of the first to third level platform universal measuring devices 6 all produce values, at the same time, the sliding direction of the slope is judged according to the value change of the angle measuring devices 63 of the first to third level platforms, when the slope body slips as a whole, the sliding directions of the levels of the slope are consistent. ② When the cable fixed pier 8 of the slope top 1 slips, the main cable is driven to be recovered by the flange wheel, the counting pulleys 61 of the universal measuring devices 6 of the other platforms produce different value sliding displacement data, the specific sliding state of each level platform needs to be calculated and analyzed according to the methods of case 1 to case 4.
