AI Technical Summary

Problems solved by technology

[0004] The current existing construction methods are limited by their own technology and can only be applied in foundation pits without internal support, and cannot be applied to assembly construction under internal support systems
In addition, when assembling components, it is necessary to closely cooperate with the lifting equipment and the assembly equipment, so it cannot be separated from the command and assistance of personnel, making it difficult to further realize automated assembly

Abstract

The invention provides a mechanized layered assembly construction structure and construction method of a fabricated underground structure, and belongs to the technical field of underground engineering. The appearance geometrical shape of a bottom foundation layer is rectangular and in a shape like a Chinese character 'Tu'; a backfill layer is the part among prefabricated parts, a foundation pit supporting structure and the bottom foundation layer; the prefabricated parts are prefabricated solid blocks with the top open, the bottom open and the top and bottom double-open form; the wall end structure of a side wall is a plane, convex face and concave face structure, and the prefabricated parts are space structure bodies assembled layer by layer from bottom to top; and the section form of the space structure bodies is rectangular, arched or other structural forms, the side walls of the prefabricated parts on the same layer are the same in size, position and wall end structure, and after the prefabricated parts are longitudinally connected, the wall ends of the side walls form flat and straight surfaces. When the upper-layer parts are assembled, an assembly device is arranged on the side walls of the lower-layer parts, the equipment cost is effectively reduced, a working face is provided for subsequent procedures, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a mechanized layered and assembled construction structure and a construction method of an assembled underground structure, belonging to the technical field of underground engineering. Background technique [0002] Urban underground projects generally adopt traditional cast-in-place construction techniques, and the production methods are still relatively extensive, and there is still a big gap compared with the requirements of high-quality development. With the continuous improvement of my country's economic level and the rapid development of society, the requirements for the transformation and upgrading of the construction industry have become very urgent. The development of prefabricated buildings is a major change in the way of construction. It is an important measure to promote the supply-side structural reform and the development of new urbanization. It is conducive to saving resources and energy, reducing construction poll...
