Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:
[0015] The embodiment of the present invention provides a minimally invasive surface excavation construction technology for underground space, specifically as follows: a construction technology for surface minimally invasive underground space excavation, using caisson technology to construct the mouth of the wound in the proposed underground space section, The area of the mouth of the wound is 1%-2% of the underground space building; the proposed underground space is divided into multiple passages arranged at intervals, so that each passage is arranged along the direction of the mouth of the wound, and the pipe jacking method is used to Pipe joints are arranged in each channel to form horizontal pipe curtains and vertical pipe curtains, and the support design and construction of pipe curtains are carried out by adopting mining method and shield t...

The invention discloses an underground space construction technique adopting underground excavation and causing little ruin to the land surface and belongs to the technical field of underground space development and construction. A ruined opening part is constructed with a well-sinking technology in a planned underground space section, and the area of the ruined opening part is 1%-2% that of an underground space building; the planned underground space is divided into multiple channels arranged at intervals, and all the channels are arranged in a communicating manner in the direction of the ruined opening part; a pipe joint is arranged in each channel with a pipe jacking method, horizontal pipe curtains and longitudinal pipe curtains are formed, steering supports used for supporting the pipe joints are arranged in the channels and comprise hydraulic temporary supports, a cushion plate and support pillars, after the hydraulic temporary supports are mounted below the pipe curtains, the support pillars are mounted on two sides and jacked through the cushion plate, the steering supports transfer upper loads to the foundation, after the strength of a main structure is 90% or higher, the hydraulic temporary supports are removed, and the support pillars are buried in the main structure in advance. The problems that the construction quality is poor in reliability, the construction efficiency is low and the building cost is high in the prior art can be solved.
Description
technical field [0001] The invention relates to a construction technology for surface minimally invasive underground space underground excavation, and belongs to the technical field of underground space development and construction. Background technique [0002] With the rapid development of urban construction in our country, urban land resources are increasingly scarce. In order to improve the utilization rate of urban land resources, realize the multiple use of land, and promote the sustainable development of the city, the three-dimensional development of underground space under existing facilities such as urban green spaces, squares, roads, and pipelines has become a demand for urban construction and development trend. [0003] In order to reduce the impact on the existing facilities on the ground, more and more areas need to use the underground excavation method to transfer the utilization space from the ground to the underground. The underground excavation method refer...
