Abstract

The invention discloses a combined type structure with a recycling effect for underground engineering. The combined type structure comprises a prefabricated part, wherein the prefabricated part comprises a plurality of steel structural members and concrete structural members; each steel structural member is arranged at the inner side of the corresponding concrete structural member; each steel structural member comprises a standard joint group and a movable joint, each standard joint group comprises an upper standard joint and a lower standard joint which are connected by the corresponding movable joint, and the width of each movable joint is smaller than the width of each of corresponding upper standard joint and lower standard joint. The combined type structure has the advantage that after each steel structural member is detached, the corresponding steel structural member is arranged on the other concrete structural member to form a new prefabricated part, so that the recycling effect is realized, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of underground engineering, and in particular relates to a recyclable combined structure for underground engineering. Background technique [0002] With the continuous development of underground space, the mechanical underground excavation method has been more and more widely used in the field of underground engineering. The construction method of mechanical excavation and prefabricated structure is the future development direction of underground space. This construction method is difficult to form a large-scale underground space project with a rectangular cross-section structure at one time due to the constraints of equipment performance and structural force characteristics. [0003] At present, the prefabricated municipal tunnels excavated by machinery are generally excavated in separate holes. The width of each tunnel is two lanes, and a certain distance is guaranteed between adjacent tunnels. If the tunnel is to...
