Description

Technical Field

[0001] The utility model relates to the technical field of settlement monitoring, in particular to a hoisting installation structure for layered settlement monitoring equipment. Background Art

[0002] Currently, there are two types of installation methods for stratified settlement monitoring equipment: general installation and hoisting installation. General installation involves placing the bottom of the monitoring equipment on the bedrock to monitor the settlement changes of the strata above it. Hoisting installation, on the other hand, is primarily used for monitoring the settlement of soil layers buried deep within the bedrock. However, because the soil layer below the stratified settlement monitoring equipment also settles when subjected to loads from above, the settlement data for each soil layer within the monitoring range is inaccurate and cannot meet the monitoring accuracy requirements.

[0003] To this end, the utility model proposes a hoisting installation structure for layered settlement monitoring equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a hoisting installation structure for layered settlement monitoring equipment, which can ensure that accurate layered settlement values ​​can be obtained when each soil layer settles due to upper loads.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0011] Each set of settlement monitoring units can monitor the settlement of each soil layer respectively, and each set of settlement monitoring units includes a settlement meter, a settlement meter measuring rod and a magnetic ring;

[0012] The settlement meter and the settlement meter rod are both arranged inside the settlement tube, the arrangement position of the settlement meter is aligned with the top of the corresponding soil layer, and the bottom of the settlement meter is connected to the settlement meter rod;

[0013] The magnetic ring is located outside the sedimentation tube and cooperates with the sedimentation instrument measuring rod.

[0014] Preferably, any two adjacent groups of settlement monitoring units are connected via a settlement meter connecting rod.

[0015] Preferably, between two adjacent groups of settlement monitoring units, the settlement meter measuring rods of the relatively upper group of settlement monitoring units and the settlement meters of the relatively lower group of settlement monitoring units are connected via a settlement meter connecting rod.

[0016] Preferably, as the embankment or roadbed filling is improved, the number of cascades of artificial measuring rods and protective pipes gradually increases, and the lengths of the artificial measuring rods and protective pipes increase.

[0017] Preferably, the outer contour of the magnetic ring is annular, and a plurality of supporting claws are arranged at equal intervals on the side wall of the magnetic ring;

[0018] Among them, the initial position of the magnetic ring in the uppermost soil layer is aligned with the middle and upper part of the settlement meter rod in the soil layer, and the initial positions of the magnetic rings in the remaining soil layers and the settlement meter rods in the corresponding soil layers are gradually moved downward.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] Combine Figures 1 to 3 As shown, the utility model proposes a hoisting installation structure for layered settlement monitoring equipment, through which the layered settlement monitoring equipment hoisting installation structure can ensure that when each soil layer settles due to upper load, the layered settlement value can also be accurately measured.

[0037] Combine Figure 2 As shown, the hoisting installation structure of the layered settlement monitoring equipment mainly includes an artificial measuring rod 1, a protection pipe 2, a settlement pipe 3, a top connecting rod 41 and a settlement monitoring unit 5.

[0038] Combine Figure 1 As shown, the artificial measuring rod 1 is arranged vertically, and a protective tube 2 is provided on the outside of the artificial measuring rod 1. The protective tube 2 is a galvanized protective tube, which can protect the artificial measuring rod 1.

[0039] The manual measuring rod 1 and the protection tube 2 both adopt a step-by-step connection structure, and the lengths of both are adjustable.

[0040] Specifically, during construction, the artificial measuring rods 1 can be gradually extended upward as the embankment and roadbed are constructed. As the embankment or roadbed is constructed, the number of artificial measuring rods 1 and protective tubes 2 connected in cascade gradually increases. Each artificial measuring rod 1 is 1 meter long, and the ends of the artificial measuring rods 1 are connected by threads. The lengths of both the artificial measuring rods 1 and protective tubes 2 are increased accordingly and extended to the top of the embankment. The lengths of the connected artificial measuring rods 1 are recorded.

[0041] Combine Figures 1 to 3 As shown, the top connecting rod 41 is arranged inside the sedimentation tube 3, the top connecting rod 41 is arranged vertically, and the sedimentation tube 3 is arranged inside the pre-opened borehole b.

[0042] The lower part of the artificial measuring rod 1 and the protection pipe 2, the top connecting rod 41, and the upper part of the settlement pipe 3 are all fixed by pouring plain concrete a.

[0043] The bottom end of the top connecting rod 41 is connected to each group of settlement monitoring units 5 in sequence, and each group of settlement monitoring units 5 can monitor the settlement of each soil layer respectively.

[0044] Combine Figure 3 As shown, the settlement monitoring unit 5 mainly includes a settlement meter 51 , a settlement meter measuring rod 52 and a magnetic ring 53 , etc., wherein the settlement meter 51 and the settlement meter measuring rod 52 are both arranged inside the settlement tube 3 .

[0045] The layout position of the settlement meter 51 is aligned with the top of the corresponding soil layer. A threaded hole is provided at the bottom of the settlement meter 51. The top of the settlement meter measuring rod 52 is provided with an external thread. The bottom of the settlement meter 51 is connected to the settlement meter measuring rod 52 through a thread. The magnetic ring 53 is located on the outside of the settlement tube 3 and cooperates with the settlement meter measuring rod 52.

[0046] Combine Figure 3 As shown, the outer contour of the magnetic ring 53 is annular. The initial position of the magnetic ring 53 in the top soil layer is aligned with the upper middle portion of the settlement meter rod 52 in that soil layer. The initial positions of the magnetic ring 53 in the remaining soil layers are gradually shifted downward, with the initial position of the magnetic ring 53 in the bottom soil layer being aligned with the lower middle portion of the settlement meter rod 52 in that soil layer.

[0047] Specifically, the magnetic ring 53 is sleeved on the outside of the settlement tube 3, and the initial position of the magnetic ring 53 is determined according to the position of the monitored soil layer. Generally, the initial position of the magnetic ring 53 corresponding to the upper soil layer should be above the middle of the corresponding settlement meter rod 52, and the initial position of the magnetic ring 53 corresponding to the lower soil layer needs to be gradually moved downward. Because the settlement of the settlement tube 3 is greater than the settlement of a single layer of soil during the hoisting installation, the settlement magnetic ring 53 corresponding to the single layer of soil will move upward relative to the settlement tube 3. Figure 1 As shown, the difference in settlement between the magnetic ring 53 corresponding to soil layer 2 and the settlement tube 3 is small, so the initial position of the magnetic ring 53 of soil layer 2 is in the upper middle part of the settlement meter rod 52, and the initial position of the magnetic ring 53 corresponding to soil layer 3 should be lower than the initial position of the magnetic ring 53 corresponding to soil layer 2. According to the rule, the initial position of the magnetic ring 53 corresponding to the lowest soil layer should be at the lower part of the settlement meter rod 52. The initial position of the magnetic ring 53 of each soil layer should be calculated based on the theoretical layered settlement and the total settlement to ensure that the settlement magnetic ring 53 of each soil layer is within the range of the settlement meter rod 52 throughout the settlement period. The settlement meter 51 determines the real-time settlement of each soil layer by measuring the distance the magnetic ring 53 moves downward.

[0048] Combine Figure 3 As shown, the sidewalls of the magnetic ring 53 are evenly spaced with multiple support claws made of spring steel sheets. When multiple sets of settlement monitoring units 5 are lowered, the support claws are secured to the circumferential sidewalls of the settlement tube 3 using water-soluble tape. Once the units are lowered into borehole b and the water-soluble tape breaks upon contact with water, the support claws of the magnetic ring 53, under their own elastic force, penetrate into the corresponding soil layer.

[0049] Combine Figures 1 to 3As shown, any two adjacent groups of settlement monitoring units 5 are connected by a settlement meter connecting rod 42, which can be used to measure the settlement of different soil layers. Specifically, between two adjacent groups of settlement monitoring units 5, the settlement meter measuring rod 52 of the relatively upper group of settlement monitoring units 5 and the settlement meter 51 of the relatively lower group of settlement monitoring units 5 are connected by the settlement meter connecting rod 42.

[0050] After the embankment and high roadbed are cleared, the installation of the hoisting installation structure of the layered settlement monitoring equipment can be started. The specific installation steps are as follows:

[0051] 1. Drill hole b at the predetermined location on the surface of the cleared foundation. The hole depth is determined based on the total thickness of each layer of the monitored stratified settlement;

[0052] 2. Determine the position of the settlement meter 51 according to the stratum stratification, and each settlement meter 51 corresponds to the top position of the corresponding soil layer;

[0053] 3. Mark the positions of the settlement meter 51 and the settlement meter rod 52 on the settlement tube 3. Insert the magnetic ring 53 into the settlement tube 3 and place it at the corresponding position of each layer. Temporarily fix the three supporting claws of the claw-type magnetic ring 53 to the outside of the settlement tube 3 with water-soluble tape. After the water-soluble tape breaks after being placed in the borehole b for a certain period of time, the supporting claws of the magnetic ring 53 are inserted into the corresponding soil layer under the action of their own elastic force.

[0054] 4. Place the sedimentation tube 3 into the borehole b, and place the sedimentation meter 51 and the sedimentation meter measuring rod 52 into the sedimentation tube 3; record the length of each sedimentation meter 51, the sedimentation meter measuring rod 52 and the sedimentation meter connecting rod 42, and record the positional relationship between each magnetic ring 53 and the corresponding sedimentation meter 51.

[0055] 5. Use plain concrete a to cast the settlement tube 3, top connecting rod 41, manual measuring rod 1, and protective tube 2 together, ensuring that the manual measuring rod 1 and protective tube 2 are vertical. Record the relative positions of the settlement tube 3 and manual measuring rod 1 in the plain concrete a.

[0056] 6. During the embankment filling process, extend the manual measuring rod 1 and the protective tube 2 to the top of the embankment at any time and record the length of the connected manual measuring rod 1;

[0057] 7. It should be noted that L1 is the reserved length of the settlement tube 3 in the plain concrete a, L2 is the reserved length of the manual measuring rod 1 and protective tube 2 in the plain concrete a, and L3 is the length of the manual measuring rod 1 exposed outside the plain concrete a. The total length of the manual measuring rod 1 is L2 + L3. Use a level to measure the elevation Z0 of the top of the manual measuring rod 1 through a reference point of known elevation and record it.

[0058] 8. The settlement of each stratum can be calculated by the real-time absolute elevation of the top of the stratified settlement monitoring equipment and the stratified settlement monitoring data;

[0059] Taking soil layer 1 as an example, the distance between the bottom of the sedimentation instrument 51 and the magnetic ring 53 corresponding to soil layer 1 is h0, and the initial absolute height of the magnetic ring 53 is H0 = Z0 - (L3 + L2 + L1 + h0);

[0060] During a certain measurement, the elevation of the top of the manual measuring rod is Z1. At this time, the absolute elevation of the magnetic ring 53 is H1 = Z1 - (L3 + L2 + L1 + h1). At this time, the settlement of the soil layer 1 is ΔS1 = H0 - H1. Similarly, the real-time settlement of each soil layer can be calculated.

[0061] Combine Figures 1 to 3 As shown, the utility model proposes a hanging installation structure of a stratified settlement monitoring device, which is connected to the stratified settlement monitoring unit 5 by an artificial measuring rod 1 exposed on the top of the embankment or the road surface. The real-time and accurate elevation of the stratified settlement monitoring unit 5 is obtained by using the elevation of the top of the artificial measuring rod 1. This solves the serious drawback of the stratified settlement monitoring unit 5 in the soil layer, especially when the embankment or roadbed is filled layer by layer during the construction period, that is, the inaccurate settlement data of each soil layer is monitored. The stratified settlement monitoring unit 5 can be applied to foundation stratification in situations where the bedrock is deeply buried, the overburden is thick, and the high roadbed is covered. Settlement monitoring; the utility model can monitor the settlement of each soil layer and meet the requirements of monitoring accuracy; in addition, the details of the installation structure are also optimized and improved, and a galvanized protective tube 2 is set on the outside of the artificial measuring rod 1 to protect it to a certain extent, effectively improving the service life of related components; during the construction period, the artificial measuring rod 1 can be extended upward section by section as the embankment and roadbed are filled, so as to realize the continuity of settlement monitoring data throughout the construction period; the installation structure of the utility model has a simple structure, a reasonable layout, and a high measurement accuracy, and has a high use value.

[0062] Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention and should be protected by the present invention.
