Description

Technical Field

[0001] The utility model belongs to the technical field of pressure monitoring, and in particular relates to a deep-water pore pressure monitoring device. Background Art

[0002] Generally, during the deep underground water installation and monitoring process, it is often necessary to insert a cannula into the ground hole to be monitored, and then place the pore pressure gauge into the cannula, and extend it into the deep underground water layer for installation and monitoring. During this period, the connecting line at one end of the pore pressure gauge must pass through the cannula to connect with the external monitoring equipment on the ground in order to receive the monitoring data of the underground pore pressure gauge. However, the connecting line on the ground can be easily pulled and displaced due to the movement of people or accidental external pulling, causing the pore pressure gauge connected to one end of the connecting line to produce an upward pulling displacement, which may deviate from the monitoring position of the deep water layer on the ground, resulting in inaccurate monitoring. Therefore, a deepwater pore pressure monitoring device is needed to solve the above problems. Utility Model Content

[0005] By setting the above structure, when the pore pressure meter is inserted into the insert pipe set in the ground, and the pore pressure meter is extended and set in a predetermined position of the deep underground water layer, the handle can be turned, and the handle will drive the second threaded rod to drive the first threaded rod to rotate. The rotation of the first threaded rod and the second threaded rod will drive the clamping block to clamp and displace towards each other through the displacement block, and finally clamp and fix the connecting wire of the upper section of the fixed ring block, so that the connecting wire and the pore pressure meter below the clamping point of the two clamping blocks will not be easily affected by the accidental pulling and movement of the ground outside 1 because of the fixation of the connecting wire section, which will help the pore pressure meter to maintain a stable installation position, thereby helping to ensure the monitoring stability of the pore pressure meter.

[0006] As a preferred embodiment, the pore pressure gauge is located below the cannula.

[0007] As a preferred implementation, the first threaded rod, the second threaded rod and the sliding rod are all located close to the edge of the central hole of the fixing ring block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a clamping block. When the pore pressure gauge is inserted into the insert pipe set in the ground and the pore pressure gauge is extended and set in a predetermined position of the deep underground water layer, the handle can be rotated, and the handle will drive the second threaded rod to drive the first threaded rod to rotate. The rotation of the first threaded rod and the second threaded rod will drive the clamping block to clamp and displace towards each other through the displacement block, and finally clamp and fix a section of the connecting wire on the upper part of the fixed ring block, so that the connecting wire and the pore pressure gauge below the clamping point of the two clamping blocks will not be easily affected by accidental pulling and movement of the ground outside 1 because of the fixation of a section of the connecting wire, which will help the pore pressure gauge to maintain a stable placement and installation position, thereby helping to ensure the monitoring stability of the pore pressure gauge.

[0014] The utility model provides rubber pads on the adjacent sides of two clamping blocks. When the two clamping blocks clamp and fix a section of the connecting line, the provision of the rubber pads can not only increase the friction clamping force on the connecting line, but also help prevent the connecting line from being easily damaged when being clamped due to the soft nature of the rubber pads.
