The invention provides positioning equipment and a positioning method of a circumferential bar for tunnel construction. The positioning equipment comprises a ground, a tunnel body, a circumferential bar body and two fixture bodies, wherein the top of the circumferential bar body makes contact with the top wall of the interior of the tunnel body, and the bottoms of the two fixture bodies are fixedly connected with the two ends of the bottom of the circumferential bar body respectively; and fixing grooves are formed in the two side walls of the interior of the tunnel body, thread grooves are formed in the groove bottoms of the fixing grooves, and the interiors of the thread grooves are in threaded connection with positioning screw parts. The positioning equipment of the circumferential bar for tunnel construction is provided with the fixing grooves, the thread grooves, the positioning screw parts, fixing rods, fixing holes and locking blocks, the locking blocks are rotated by a tool andcan also be rotated manually, so the positioning screw parts are in threaded connection with the interiors of the thread grooves, the fixing rods and the fixture bodies are fixed, and the effect of facilitating the fixation of the fixture bodies is reached.
Description
[0001] This application is a divisional application of an invention titled CN201810988397.8 with an application date of August 28, 2018, and a positioning device for hoop ribs for tunnel construction. technical field [0002] The invention relates to the technical field of hoop rib positioning equipment, in particular to a hoop rib positioning device and a positioning method for tunnel construction. Background technique [0003] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing t...
