[0002] The observation pier is a device used to observe changes in ground settlement, displacement, etc. It is widely used in foundation pit engineering, geological engineering and other fields.

[0003] As infrastructure ages and environmental factors take their toll, there is a growing need to be able to monitor the health of structures in real time. Observation piers are a monitoring tool that are often installed on bridges, dams, and other critical structures so that engineers can collect data on displacement, crack width, and other key metrics.

[0004] Currently, observation piers on the market are usually made of stainless steel or concrete. When stainless steel observation piers are used on site, they are usually fixed to a hard foundation with expansion screws, but the screws will loosen due to long-term vibration, and the hollow support column is prone to deformation. The concrete pouring observation pier has a complicated process and requires mold erection, concrete mixing, etc., which is cumbersome to make.

[0005] The applicant found that the traditional stainless steel observation piers have shortcomings in measurement work: the screws of the stainless steel observation piers will become loose, the hollow supporting columns are easy to deform, and the concrete pouring process of the observation piers is complicated.

[0006] In view of this, an observation pier with concrete injection holes is proposed. Utility Model Content

[0007] The utility model aims to provide an observation pier with a concrete injection hole, which can be more stable and ensure that the observation pier will not move easily.

[0010] By adopting the above technical solution, the installation of the observation pier is simplified during measurement and monitoring, the stability of the observation pier is enhanced, and it is ensured that the observation pier will not move easily.

[0011] Furthermore, the base is a square plate.

[0012] Furthermore, the mounting holes are distributed at the four corners of the base.

[0013] Furthermore, the support column is a hollow tube structure.

[0014] Furthermore, the base, support column, centering plate and connecting screws are all made of metal.

[0015] Furthermore, the connecting screw is located at the center of the centering plate.

[0016] Furthermore, the base, support column, centering plate and connecting screws are coaxially arranged.

[0017] Furthermore, the concrete injection hole is located in the upper part of the support column.

[0018] Beneficial Effects

[0019] Compared with the prior art, the observation pier with a concrete injection hole of the utility model has the advantages of being easy and stable to install, and the observation pier will not move easily. BRIEF DESCRIPTION OF THE DRAWINGS
