Embodiment 1
[0058] Embodiment 1: In this embodiment, the detailed construction process will be described in detail for the underground excavation structure project in combination with the structure and construction method.
[0059] For example: a five-storey underground parking lot is proposed, with a column grid size of 4mx6m, a floor height of 3.6m, a total building length of 92m, a width of 30m, a main structure jacking of 80m, and a building area of 14,000 square meters. The main process is as follows:
[0060] Process one: if image 3 As shown; the originating shaft 1 and the receiving shaft 2 are completed by the open cut method; the dimension of the originating shaft is 8mX34m, and the size of the receiving shaft is 4mX31m. machine.
[0061] Process two: if Figure 4 As shown in the figure; set the leading guide hole 8 with a diameter of 20cm, which is completed by using a pipe curtain machine or a small pipe jacking machine or a horizontal drilling rig; the small guide hole i...

The invention belongs to the technical field of underground excavation engineering, and in particular relates to an underground building modular construction system and its construction method, which effectively solves the technical problem that the construction of underground space structure engineering is difficult, and utilizes the modular construction of prefabricated construction technology, improve the safety and mechanization of underground engineering, and provide a modular construction system for underground buildings, including an originating shaft and a receiving shaft set in the underground excavation structure, and a jacking device is arranged in the originating shaft, and the There is a traction device in the receiving shaft, and a leading guide tunnel is set between the originating shaft and the receiving shaft, and a steel cable or a steel rod is arranged in the leading tunnel, and one end of the steel cable or steel rod is connected to the traction device in the receiving shaft. connection; the other end is connected to the connector reserved on the outside of the main structure of the building. The construction and method of this structure are suitable for the development of large-scale underground space, effectively avoiding large-scale open-cut projects, with little impact on the ground environment and high social benefits .
Description
technical field [0001] The invention belongs to the technical field of underground excavation engineering; in particular, it relates to an underground building modular construction system and a construction method thereof. Background technique [0002] With China's reform and opening up and modern urban construction, the construction and utilization of underground space has been paid more and more attention by the country; and in the process of urbanization in China, the rapid concentration of urban population makes land resources become particularly scarce. The demand for the development and utilization of underground space in the whole society is becoming more and more prominent; however, the usual underground construction method is to adopt the construction method of combining support and open excavation, but the biggest problem brought by this traditional method is that it needs to be ground. The overall excavation not only affects the surrounding environment, but also s...
