Embodiment Construction
[0031]A method for vertical framing prefabrication of an open-cut underground passage proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. For the convenience of description, the "up" and "down" described below are consistent with the directions of up and down in the drawings, but this should not be a limitation of the technical solution of the present invention.

The invention discloses an open-cutting vertical amplitude selection prefabricating construction method for an underground passage and aims at solving the problems that the weight of a component prefabricated in a segmentation manner is large, and the on-site hoisting difficulty is large. An underground passage structure is subjected to vertical amplitude selection in advance, and is transversely divided into a plurality of upper segments and lower segments of the underground passage, and the upper segments and the lower segments are subjected to factory-like prefabricating; the lower segments of the underground passage are sequentially ejected in place to be spliced into a lower structure of the underground passage through an ejecting system, and a moving and transporting splicing system is installed in the completed lower structure of the underground passage to perform splicing construction of the upper segments of the underground passage; a vertical adjusting mechanism and a horizontal adjusting mechanism are installed between a supporting body and the upper segments of the underground passage, and the upper segments of the underground passage are stably fixed to the supporting body; and the upper segments of the underground passage are transported to preset positions sequentially by means of a self-walking type slide rail installed at the bottom of the supporting body, the upper segments of the underground passage are sequentially transported to preset positions and spliced with the corresponding lower segments of the underground passage in place, and the upper segments of the underground passage and the lower segments of the underground passage are connected into the overall underground passage structure.
Description
technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to an open-cut vertical framing prefabrication construction method for an underground passage. Background technique [0002] With the continuous advancement of the urbanization process, the traffic congestion in large and medium-sized cities is becoming more and more serious, and the construction of underground passages will surely occupy an important position in the future construction of cities. At present, the construction of long-distance underground passages in cities mainly adopts the open-cut and sequential method, which mainly includes two stages: excavation of earthwork layer by layer and sequential construction of structures. Since the traditional underground passage structure is mainly poured from bottom to top on site, it has the following disadvantages: 1. Poor construction conditions for concrete pouring on site, low construction accuracy, ...
