[0002] Tunnel construction is also called tunnel engineering. Tunnel engineering is a building built underground or underwater or in a mountain to lay railways or build roads for motor vehicles to pass. According to its location, it can be divided into three categories: mountain tunnel engineering, underwater tunnel engineering and urban tunnel engineering. Mountain tunnel engineering is to pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnel engineering is to pass under rivers or straits or under the sea; urban tunnel engineering is to pass underground in cities to meet the needs of railways passing through large cities. Among these three types of tunnel engineering, mountain tunnel engineering is the most constructed. However, when constructing tunnel arches, arch support mechanisms are needed to support and fix them in order to improve the safety of construction workers at work.

[0003] The existing arch support mechanism usually supports the tunnel arch with a single set of support components. This design easily reduces the stability of the tunnel arch support when it is fixed, and increases the danger for construction workers when working. Utility Model Content

[0030] The utility model is provided with a first arch support plate 1, a second arch support plate 101, a first support column 102, a third arch support plate 2, a fourth arch support plate 201, a second support column 202, an adjusting rod 203, a connecting seat 3, a fixing seat 6 and a cylinder 7 and other components for use in combination, so as to facilitate the tunnel arch during construction, so as to play a supporting role for the tunnel arch, and also improve the safety of the construction personnel, and at the same time, by providing a double-layer arch support plate, it is convenient to improve the stability effect during support and fixing, and increase the safety of the construction personnel during construction;

[0031] However, the first arched support plate 1, the second arched support plate 101 and the third arched support plate 2, the fourth arched support plate 201 are separated by the adjusting rod 203, so as to increase the range of the tunnel arch support and fixation.

[0032] Furthermore, when the tunnel arch needs to be supported, the handgrip 13 is held by hand to push the support mechanism to the position in the tunnel arch that needs to be supported and fixed and then stop. At the same time, the handgrips 13 at both ends of the back of the support mechanism are held by hand to drive the first arch support plate 1 and the second arch support plate 101 to move outward through the adjustment rod 203, thereby expanding the support range of the tunnel arch;

[0033] Then, by starting the cylinder 7, its output end drives the fixed seat 6 to move upward, so that the fixed seat 6 drives the arched support plate on the connecting seat 3 to fit and support the inner top of the tunnel arch, thereby facilitating the support of the tunnel arch, thereby improving the stability of the tunnel arch support, and also reducing the safety of construction workers at work.
