Abstract
This invention relates to the field of construction support equipment technology and discloses a tunnel construction support device, including columns. A top rod is fixedly connected to the top of each column. Two columns are present, forming a portal frame with the top rod. A support rod is fixedly connected to the inner side of each column below the top rod. A top support mechanism is provided on the upper surface of the top rod, and an adjustment mechanism is provided in the middle of the support rod to adjust the height of the top support mechanism. This invention provides a tunnel construction support device. Through the coordinated arrangement of the top support mechanism and the adjustment mechanism, the height of the upper top support mechanism can be adjusted during construction, ensuring that the top support mechanism supports the top of the tunnel to prevent falling rocks from the tunnel ceiling from injuring construction workers. A scale on the column allows for quick detection of changes and timely response.
