Description

Technical Field

[0001] This invention relates to the technical field of simple deep horizontal displacement monitoring devices for retaining piles, specifically a simple deep horizontal displacement monitoring device for retaining piles and its construction method. Background Technology

[0002] In engineering fields such as foundation pit excavation and tunnel construction, in order to ensure project safety, it is necessary to measure the inclination of the concrete piles in the foundation pit. At present, the commonly used measuring equipment is an inclinometer, which is mainly used in conjunction with an inclinometer tube. The inclinometer tube is tied to the pile reinforcement cage beforehand. After the pile concrete is poured and formed, the pile head is broken to expose the inclinometer tube. At this time, the probe of the inclinometer can be inserted into the inclinometer tube to measure the deep horizontal displacement of the pile.

[0003] However, in existing technologies, the connection between inclinometer tubes in monitoring devices for deep horizontal displacement of retaining piles typically uses a tongue-and-groove fit, secured with self-tapping screws after drilling holes in the tube surface. While this connection method achieves the connection of inclinometer tubes to a certain extent, it presents several problems. In field construction environments, specialized self-tapping screwdrivers must be carried and used to install the screws, which undoubtedly increases the complexity and inconvenience of the construction. Due to the complex conditions of field construction sites, which may be limited by various factors such as terrain and weather, the use of self-tapping screwdrivers is often subject to numerous interferences, resulting in low construction efficiency. Moreover, the entire process of drilling and installing screws is cumbersome, requiring significant time and manpower, severely impacting the progress of the entire monitoring device installation and failing to meet the requirements of efficient construction. Summary of the Invention

[0004] The purpose of this invention is to provide a simple device and construction method for monitoring deep horizontal displacement of support piles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clinometer tube, wherein a convex ring is provided at the first end of the clinometer tube, and multiple sets of first through holes are provided on both sides of the convex ring; a connecting ring is provided at the other end of the clinometer tube, and an insertion groove is provided on the inner side of the connecting ring; an annular groove is provided on the outer side of the insertion groove inside the connecting ring; a telescopic arc plate is elastically connected to both sides of the annular groove; and multiple sets of first insertion posts are provided on the inner side of the telescopic arc plate.

[0006] Preferably, a first spring is provided in the annular groove. The outer side of the first spring is connected to the outer inner wall of the annular groove, and the inner side of the first spring is connected to a telescopic arc plate. The first spring can, through tension, extend multiple sets of first insertion posts provided on the inner side of the telescopic arc plate from the through holes opened on the inner side of the annular groove into the insertion grooves opened on the inner side of the connecting ring.

[0007] Preferably, a through groove is provided in the middle of the inner side of the annular groove, and a connecting steel wire rope is connected in the through groove. The two ends of the connecting steel wire rope extend from the outside of the connecting ring. Pulling the two ends of the connecting ring can cause the connecting steel wire rope to drive the telescopic arc plate to tighten fully through the through groove.

[0008] Preferably, the connecting ring has two sets of insertion slots parallel to the telescopic arc plate, and the telescopic arc plate has a second through slot in the middle. The two sets of insertion slots are perpendicular to the insertion slots in the middle of the telescopic arc plate in the contracted state and the open state, respectively.

[0009] Preferably, the two ends of the connecting wire rope are connected to plug rods, which can be inserted into the second through slot in the middle of the telescopic arc plate through the plug groove, respectively for the telescopic arc plate in the contracted state and the open state.

[0010] Preferably, the connecting ring has a telescopic groove on one side of the middle of the insertion groove, and a second spring is provided in the telescopic groove. One side of the second spring is connected to the inner wall of the telescopic groove, and the other side of the second spring is connected to the telescopic plate. The second spring can drive the telescopic plate to extend and retract in the telescopic groove.

[0011] Preferably, a limiting hole is provided at the top of the plug rod, and two sets of plug posts are provided on the outer side of the telescopic plate. The two sets of plug slots on both sides of the plug post are parallel to the limiting hole at the top of the plug rod. The plug post can be inserted into the limiting hole at the top of the plug rod by the elastic force of the second spring at the rear end of the telescopic plate.

[0012] Preferably, the connecting ring has an extension opening at the top center of the telescopic groove, and a deflector plate is connected to the top rear of the telescopic plate. The deflector plate extends out of the telescopic groove through the extension opening. By deflecting the deflector plate, the telescopic plate can cause the plug-in post to retract into the telescopic groove.

[0013] A simple construction method for a deep horizontal displacement monitoring device for support piles includes the following steps:

[0014] Step 1: Assembly. First, insert the convex ring at one end of one set of inclinometer tubes into the insertion groove on the inner side of the connecting ring at the end of another set of inclinometer tubes. Then, by moving the actuating plate, the actuating plate will push the telescopic plate against the second spring and retract it into the telescopic groove. After that, by taking out the insertion rods inserted into the insertion grooves on both sides of the connecting ring, the limitation on the telescopic arc plate in the annular groove in the middle of the connecting ring is removed. The initial position of the insertion rod is in the insertion groove on the outer side of the connecting ring of the two sets of insertion grooves on both sides of the connecting ring. After taking out the insertion rod, the first spring in the annular groove will spring the telescopic arc plate inward through the tension, so that the first insertion post on the inner side of the telescopic arc plate extends out from the through hole on the inner side of the annular groove and is inserted into the first through hole on both sides of the convex ring inserted in the insertion groove, thus fixing the connection of the two sets of inclinometer tubes.

[0015] Step 2: Installation; Place the assembled inclinometer tube on one side of the wire cage, and wrap the connecting wire rope around the wire cage, leaving enough space for the insertion rod to be inserted into the insertion slots on both sides of the inclinometer tube. At this time, the connecting wire rope starts to pull the telescopic arc plate through the through slot to further tighten it, preventing the first spring from causing slight contraction of the telescopic arc plate, which would lead to unstable connection between the two sets of inclinometer tubes. At the same time, make the second through slot in the middle of the telescopic arc plate precisely perpendicular to the insertion slots on both sides of the inclinometer tube. While tightening the telescopic arc plate, fix the inclinometer tube to the wire cage.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention proposes a simple deep horizontal displacement monitoring device and construction method for support piles. When assembling two sets of inclinometer tubes, firstly, the convex ring at one end of one set of inclinometer tubes is inserted into the insertion groove on the inner side of the connecting ring at the end of the other set of inclinometer tubes. Then, by moving the actuating plate, the actuating plate drives the telescopic plate to compress the second spring and retract into the telescopic groove. Afterward, by removing the insertion rods inserted into the insertion grooves on both sides of the connecting ring, the limiting position of the telescopic arc plate in the annular groove in the middle of the connecting ring is removed. The initial position of the insertion rod is located in the insertion groove on the outer side of the connecting ring of the two sets of insertion grooves on both sides of the connecting ring. After removing the insertion rod, the first spring in the annular groove uses tension to spring the telescopic arc plate inward, causing the first insertion post on the inner side of the telescopic arc plate to extend from the through hole on the inner side of the annular groove and be inserted into the first through hole on both sides of the convex ring inserted into the insertion groove, thus fixing the connection of the two sets of inclinometer tubes. Then, the assembled inclinometer tubes are placed... On one side of the wire cage, the connecting wire rope is wound around the wire cage, leaving enough space for the insertion rod to be inserted into the insertion slots on both sides of the inclinometer tube. At this time, the connecting wire rope begins to pull the telescopic arc plate through the through slot to further tighten it, preventing the first spring from causing slight contraction of the telescopic arc plate, which would lead to instability in the connection between the two sets of inclinometer tubes. At the same time, the second through slot in the middle of the telescopic arc plate is precisely perpendicular to the insertion slots on both sides of the inclinometer tube. While tightening the telescopic arc plate, the inclinometer tube is fixed to the wire cage. Finally, by moving the actuating plate again, the actuating plate is moved to retract the telescopic plate into the telescopic plate. Then, the insertion rod is inserted through the insertion slots on both sides of the inclinometer tube into the second through slot in the middle of the telescopic arc plate to fix the telescopic arc plate. After that, the actuating plate is released, and the second spring in the telescopic slot begins to insert the telescopic plate on the outside of the second spring into the limiting hole at the top of the insertion rod through tension, thus completing the assembly and installation of the inclinometer tube.

[0026] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 7This invention provides a technical solution: a clinometer tube 1, with a protruding ring 2 at one end, and multiple sets of first through holes 5 on both sides of the protruding ring 2; a connecting ring 3 at the other end, with an insertion groove 4 on the inner side of the connecting ring 3; and an annular groove 6 on the outer side of the insertion groove 4 inside the connecting ring 3; telescopic arc plates 8 elastically connected to both sides of the annular groove 6; multiple sets of first insertion posts 9 on the inner side of the telescopic arc plates 8; and a first spring 7 disposed in the annular groove 6, with the outer side of the first spring 7 connected to the outer side of the annular groove 6. On the inner wall, the inner side of the first spring 7 is connected to the telescopic arc plate 8. The first spring 7 can use tension to extend multiple sets of first insertion posts 9 on the inner side of the telescopic arc plate 8 from the through holes opened on the inner side of the annular groove 6 into the insertion groove 4 opened on the inner side of the connecting ring 3; the first spring 7 in 6 uses tension to spring the telescopic arc plate 8 inward, so that the first insertion posts 9 on the inner side of the telescopic arc plate 8 extend from the through holes opened on the inner side of the annular groove 6 and are inserted into the first through holes 5 opened on both sides of the protruding ring 2 in the insertion groove 4, thereby fixing the connection of the two sets of inclinometer tubes 1;

[0028] A through groove 10 is provided in the middle of the inner side of the annular groove 6. A connecting steel wire rope 11 is connected in the through groove 10. The two ends of the connecting steel wire rope 11 extend from the outside of the connecting ring 3. Pulling the two ends of the connecting ring 3 can cause the connecting steel wire rope 11 to pass through the through groove 10 and fully tighten the telescopic arc plate 8. The connecting ring 3 has two sets of insertion grooves 13 parallel to the telescopic arc plate 8. A second through groove 21 is provided in the middle of the telescopic arc plate 8. The two sets of insertion grooves 13 are perpendicular to the insertion grooves 13 in the middle of the telescopic arc plate 8 in the retracted state and the open state, respectively. Insertion rods 12 are connected to both ends of the connecting steel wire rope 11. The insertion rods 12 can pass through the insertion grooves 13 and be inserted into the second through groove 21 in the middle of the telescopic arc plate 8. The telescopic arc plate 8 is in both the contracted and open states. The connecting ring 3 has a telescopic groove 14 on one side of the middle of the insertion groove 13. A second spring 15 is installed in the telescopic groove 14. One side of the second spring 15 is connected to the inner wall of the telescopic groove 14, and the other side of the second spring 15 is connected to the telescopic plate 16. The second spring 15 can drive the telescopic plate 16 to extend and retract in the telescopic groove 14. By moving the actuating plate 19, the actuating plate 19 drives the telescopic plate 16 to squeeze the second spring 15 and retract into the telescopic groove 14. Then, by taking out the insertion rod 12 inserted into the insertion groove 13 on both sides of the connecting ring 3, the limitation on the telescopic arc plate 8 in the annular groove 6 opened in the middle of the connecting ring 3 is removed.

[0029] A limiting hole 20 is provided at the top of the plug rod 12. Two sets of plug posts 17 are provided on the outer side of the telescopic plate 16. The plug posts 17 are parallel to the two sets of plug slots 13 on both sides of the inclinometer tube 1 and the limiting hole 20 at the top of the plug rod 12. The plug posts 17 can be inserted into the limiting hole 20 at the top of the plug rod 12 by the elastic force of the second spring 15 at the rear end of the telescopic plate 16. The connecting ring 3 has an extension opening 18 at the top center of the telescopic groove 14. The top of the telescopic plate 16 is connected to the actuating plate 19. The actuating plate 19 extends out of the telescopic groove 14 through the extension opening 18. Actuating the actuating plate 19 can cause the telescopic plate 16 to drive the plug posts 17 to retract into the telescopic groove 14. When the actuating plate 19 is released, the second spring 15 in the telescopic groove 14 begins to insert the telescopic plate 16 on the outer side of the second spring 15 into the limiting hole 20 at the top of the plug rod 12 by tension, thus completing the assembly and installation of the inclinometer tube 1.

[0030] In practical use, when assembling the two sets of inclinometer tubes 1, first insert the convex ring 2 at one end of one set of inclinometer tubes 1 into the insertion groove 4 opened on the inner side of the connecting ring 3 at the end of the other set of inclinometer tubes 1. Then, by moving the actuating plate 19, the actuating plate 19 drives the telescopic plate 16 to squeeze the second spring 15 and retract it into the telescopic groove 14. Then, by taking out the insertion rod 12 inserted into the insertion groove 13 on both sides of the connecting ring 3, the limitation of the telescopic arc plate 8 in the annular groove 6 opened in the middle of the inner part of the connecting ring 3 is removed, and the initial movement of the insertion rod 12 is... The initial position is located in the two sets of insertion slots 13 on both sides of the connecting ring 3. After the insertion rod 12 is taken out, the first spring 7 in the ring groove 6 uses tension to push the telescopic arc plate 8 inward, so that the first insertion post 9 on the inner side of the telescopic arc plate 8 extends out from the through hole on the inner side of the ring groove 6 and is inserted into the first through hole 5 on both sides of the protruding ring 2 in the insertion groove 4, thus connecting and fixing the two sets of inclinometer tubes 1. Then, the assembled inclinometer tube 1 is placed on one side of the wire cage, and the connecting wire rope is used to fix it. 11 is wound around the wire cage, with a distance reserved for the insertion rod 12 to be inserted into the insertion slots 13 on both sides of the inclinometer tube 1. At this time, the connecting wire rope 11 starts to pull the telescopic arc plate 8 further tighten through the through slot 10, to prevent the first spring 7 from causing the telescopic arc plate 8 to contract slightly, which would lead to instability in the connection between the two sets of inclinometer tubes 1. At the same time, the second through slot 21 opened in the middle of the telescopic arc plate 8 is precisely perpendicular to the insertion slots 13 on both sides of the inclinometer tube 1. While tightening the telescopic arc plate 8, the inclinometer tube 1 is fixed to the wire cage. Finally, by moving the actuating plate 19 again, the actuating plate 19 causes the telescopic plate 16 to retract into the telescopic plate 16. Then, the insertion rod 12 is inserted into the second through groove 21 in the middle of the telescopic arc plate 8 through the insertion groove 13 on both sides of the inclinometer tube 1, thus fixing the telescopic arc plate 8. After that, the actuating plate 19 is released, and the second spring 15 in the telescopic groove 14 begins to insert the telescopic plate 16 on the outside of the second spring 15 into the limiting hole 20 opened at the top of the insertion rod 12 through tension, thus completing the assembly and installation of the inclinometer tube 1.
