Problems solved by technology

[0003] Under the existing technical conditions, the inclinometer pipe holes and the groundwater level pipe holes (piezometer pipe holes) are arranged independently. The water level in the sealed inclinometer tube cannot represent the actual water level of the monitored body. If other technical measures are used to make the water level in the inclinometer tube represent the water level of the monitored rock mass, the piezometer and cable installed in the tube will affect the water level of the monitored body. Inclinometer works normally

Embodiment Construction

[0027] An inclinometer hole piezometer device, such as figure 1 As shown, it consists of a standard inclinometer tube 1, a standard inclinometer tube joint 2, a seepage plate 3 placed between the standard joints, a flower hole tube 4 and a standard bottom cover 9 for the inclinometer tube. The standard inclinometer tube 1 is divided into Segmental inclinometer pipe, each section is connected by standard joint 2; the standard joint 2 of the inclinometer pipe is connected by segmented standard inclinometer pipe 1; the seepage plate 3 is a PVC or aluminum or ABS circular plate, the plate There is a round hole drilled in the middle, and it is placed between the joint of the lowest section inclinometer pipe 1 and the flower hole pipe 4, which can not only make the groundwater in the flower hole pipe 4 flow into the inclinometer pipe, but also prevent the inclinometer probe from continuing to flow during monitoring. Downward; the flower hole pipe 4 is processed by the standard incli...

Abstract

The invention discloses an inclination measuring hole osmometer device and an installation method. The inclination measuring hole osmometer device is provided with a borehole; an inclination measuring pipe, a water seepage plate, a flower hole pipe and an inclination measuring pipe standard bottom cover; the water seepage plate is installed between the bottom part of the inclination measuring pipe and the top part of the flower hole pipe, and is used for separating the inclination measuring pipe and the flower hole pipe; an osmometer is installed in the flower hole pipe; the bottom part of the flower hole pipe is provided with the inclination measuring pipe standard bottom cover. According to the device and the method, an inclination measuring pipe hole and a groundwater level pipe hole (a pressure measuring pipe hole) are combined by the borehole into one; not only can the deep horizontal displacement of the borehole be monitored, but also the groundwater level and the osmotic pressure can also be monitored; therefore the monitoring on the inclination measuring pipe hole and the pressure measuring pipe hole through the same pipe hole is realized.

Description

technical field [0001] The invention relates to a safety monitoring method and device for geotechnical engineering, which is suitable for the specific conditions of monitoring the horizontal displacement of an inclinometer hole and the monitoring of an underground water level hole and seepage pressure. Background technique [0002] As we all know, in the safety monitoring of geotechnical engineering, deep horizontal displacement, groundwater level and seepage pressure are important items of geotechnical engineering monitoring. Under the existing technical conditions, the inclinometer is used to monitor the horizontal displacement of the deep part, that is, the inclinometer is drilled in the monitoring body and the inclinometer is buried, and the horizontal displacement of the deep part can be measured by putting the movable inclinometer into the pipe ;Drilling and installation of water level pipes are also required to monitor groundwater level holes, soaking lines, seepage a...
