Description

Technical Field

[0001] The utility model relates to the technical field of soil pressure gauges, in particular to a device for monitoring soil stress around a buried pipeline. Background Art

[0002] Soil pressure gauges are used in the process of monitoring soil stress around buried pipelines. Soil pressure gauges mainly use the principles of soil mechanics to determine the pressure state of the soil by measuring the pressure of the soil on the sensor.

[0003] During the installation process, the earth pressure gauge must be dug at the designated location and depth, ensuring smooth pit walls to prevent uneven force from damaging the sensor. However, when the soil is rocky, smooth pit walls may not be guaranteed. Therefore, extra care must be taken when placing the earth pressure gauge in the pit to prevent scratches from rocks and other debris.

[0004] To address the above problems, the traditional earth pressure gauge can be improved to increase its protection so that the earth pressure gauge can be prevented from being scratched when placed in the installation pit, thereby reducing the burden on the staff. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problem and to provide a device for monitoring soil stress around buried pipelines.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for monitoring soil stress around a buried pipeline includes an earth pressure gauge, which extends into a sleeve groove formed on a sleeve block, and two sleeve blocks surround the earth pressure gauge. A screw groove and a slide groove are formed on the sleeve block, and the sleeve block abuts against a rotating block. A round block is fixed on the rotating block and is slidably connected to the slide groove. A screw is rotatably connected to the rotating block, and the screw is threadedly connected to the screw groove. The screw is controlled to rotate by a control member.

[0008] Preferably, the control member includes a placement rod fixedly connected to the screw rod, the placement rod is rotatably connected to a rotating block, and a vertical rod is fixed on the rotating block, the vertical rod passes through a through hole opened on the connecting rod, the connecting rod is slidably connected to the placement rod, and the vertical rod is connected to a screw sleeve through a thread.

[0009] Preferably, a slot is provided on the sleeve block, through which the soil pressure gauge can be directly observed.

[0010] Preferably, when the round block is separated from the sliding groove on the sleeve block, the screw rod is still connected to the screw groove on the sleeve block through a threaded connection. At this time, by applying force to the placement rod, the two sleeve blocks can be separated from the soil pressure gauge.

[0011] Preferably, an elastic gasket is provided on the portion of the sleeve that contacts the soil pressure gauge.

[0012] Preferably, the sleeve block is made of a transparent material, and the outer wall of the sleeve block is provided with a wear-resistant layer.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In this application, the earth pressure gauge is surrounded by two blocks and placed in the installation pit to prevent the earth pressure gauge from being damaged by collision with stones on the inner wall of the pit during the installation process.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] This utility model provides a technical solution, please refer to Figure 1-Figure 3 :

[0024] A device for monitoring soil stress around a buried pipeline includes an earth pressure gauge 1, which extends into a sleeve groove 3 formed in a sleeve block 2. The portion of the sleeve groove 3 contacting the earth pressure gauge 1 is provided with an elastic gasket. The sleeve block 2 is made of a transparent material, and its outer wall is provided with a wear-resistant layer. The two sleeve blocks 2 surround the earth pressure gauge 1. Screw grooves 5 and chute 6 are formed in the sleeve blocks 2, and the sleeve blocks 2 abut against a rotating block 8. A circular block 9 is fixed to the rotating block 8 and slidably connected to the chute 6. A screw rod 10 is rotatably connected to the rotating block 8, and the screw rod 10 is threadedly connected to the screw groove 5. The screw rod 10 is controlled to rotate by a control member. A slot 4 is formed in the sleeve block 2, through which the earth pressure gauge 1 can be directly observed.

[0025] Example 2:

[0026] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the control member includes a placement rod 7 fixedly connected to a screw rod 10. The placement rod 7 is rotatably connected to a rotating block 11, and a vertical rod 12 is fixed to the rotating block 11. The vertical rod 12 passes through a through hole 14 provided on a connecting rod 13. The connecting rod 13 is slidably connected to the placement rod 7, and the vertical rod 12 is threadedly connected to a screw sleeve 15. When the round block 9 is separated from the chute 6 on the sleeve block 2, the screw rod 10 is still threadedly connected to the screw groove 5 on the sleeve block 2. At this time, by applying force to the placement rod 7, the two sleeve blocks 2 can be separated from the earth pressure gauge 1. Subsequently, the two placement rods 7 can be removed from the placement pit, leaving only the earth pressure gauge 1 body in the pit, thus completing the placement of the earth pressure gauge 1 in its entirety into the placement pit.

[0027] In summary, the present embodiment provides a device in which the sleeve grooves 3 of the two sleeve blocks 2 are fitted over the earth pressure gauge 1, thereby enclosing the earth pressure gauge 1 under the action of the two sleeve blocks 2. A rotating block 8 is brought into contact with one sleeve block 2, and the round block 9 at the bottom of the rotating block 8 is inserted into the slide groove 6 provided on the sleeve block 2. Subsequently, the placement rod 7 is rotated, causing the screw rod 10 at the bottom of the rotating block 8 to be threadedly connected to the screw groove 5 on the sleeve block 2.

[0028] Following the above process, the two placement rods 7 are connected to the corresponding sleeve blocks 2, and the connecting rod 13 is then sleeved onto the two placement rods 7 until the bottom of the connecting rod 13 abuts against the rotating block 11 and the vertical rod 12 passes through the through hole 14 on the rotating block 11. The screw sleeve 15 is threadedly connected to the vertical rod 12 to connect the two placement rods 7 into one.

[0029] Then, by controlling the connecting rod 13 or the placement rod 7, the sleeve 2 and the earth pressure gauge 1 can be placed into the excavated placement pit until they reach the bottom of the pit. The screw sleeve 15 can then be rotated to disengage from the vertical rod 12. The placement rod 7 can then be rotated in sequence, causing the round block 9 to disengage from the chute 6 while the screw 10 remains threadedly connected to the screw groove 5. At this point, force can be applied to the placement rod 7, causing the screw 10 at the bottom of the placement rod 7 to separate the two sleeves 2 from the earth pressure gauge 1, exposing the earth pressure gauge 1 in the placement pit. Finally, the placement rod 7 and sleeve 2 can be removed from the placement pit to proceed with subsequent operations.

[0030] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
