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...

Abstract

The invention belongs to the technical field of underground excavation engineering and particularly relates to a modular construction system of an underground building and a construction method thereof which effectively solve the technical problem of high construction difficulty of underground space structure engineering and improve the safety and the degree of mechanization of underground engineering by utilizing a modular construction technology of fabricated construction. The modular construction system, provided by the invention, of the underground building comprises an original well and a reception well which are arranged in an underground excavation structure, wherein a pushing device is arranged in the original well, a traction device is arranged in the reception well, an antecedent pilot tunnel is also arranged between the original well and the reception well, a steel cable or a section steel pull rod is arranged in the antecedent pilot tunnel, one end of the steel cable or the section steel pull rod is connected with the traction device in the reception well, and the other end of the steel cable or the section steel pull rod is connected with a connecting piece reserved on the outer side of a main body structure of the building. The structural construction and the method thereof are suitable for development of huge underground spaces, therefore, a large area of open excavation engineering can be effectively avoided, the influence on the ground environment is small, and the social benefit is high.

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...
