Embodiment 1

[0046] Embodiment 1: The following is a detailed description of the combined construction method of the large-span underground space structure of the structure; Figure 3~6 Shown:

[0047] Step 1: Longitudinal tunnel mechanized construction; use shield machine and pipe jacking machine to construct two parallel tunnels; advance tunnel as the longitudinal load-bearing structure of space structural unit, its cross-sectional shape can be rectangular or similar rectangular tunnel, circular tunnel Or horseshoe tunnel.

[0048] Step 2: Transverse tube curtain mechanization construction; use tube curtain machine for tube curtain construction to form a span-direction structure; tube curtain machine starts from one tunnel and receives from the other tunnel. After the tube curtain is formed, it is the tube curtain of the two tunnels. Pouring supports at the ends to fix both ends of the tube curtain; where the structure is located in a layer with a lot of water, a tube curtain structure with a...

Embodiment 2

[0052] Embodiment 2: The following is a detailed description of the construction method of the depth direction combination of the large-span underground space structure set up in the structure; Figure 7~10 Shown:

[0053] Step 1: Longitudinal tunnel mechanized construction; use shield machine and pipe jacking machine to construct two parallel tunnels; advance tunnel as the longitudinal load-bearing structure of space structural unit, its cross-sectional shape can be rectangular or similar rectangular tunnel, circular tunnel Or horseshoe tunnel.

[0054] Step 2: Transverse tube curtain mechanization construction; use tube curtain machine for tube curtain construction to form a span-direction structure; tube curtain machine starts from one tunnel and receives from the other tunnel. After the tube curtain is formed, it is the tube curtain of the two tunnels. Pouring supports at the ends to fix both ends of the tube curtain; where the structure is located in a layer with a lot of wate...

Embodiment 3

[0058] Embodiment 3: The following is a detailed description of the construction method of the arch structure tube-curtain combination of the large-span underground space structure set up in the structure; Figure 11-14 Shown:

[0059] Step 1: Longitudinal tunnel mechanized construction; use shield machine and pipe jacking machine to construct two parallel tunnels; advance tunnel as the longitudinal load-bearing structure of space structural unit, its cross-sectional shape can be rectangular or similar rectangular tunnel, circular tunnel Or horseshoe tunnel.

[0060] Step 2: The mechanized construction of the horizontal curved tube curtain; the curved tube curtain machine is used to construct the tube curtain to form a structure in the span direction; the tube curtain machine starts from one tunnel and receives from the other tunnel. After the tube curtain is formed, it is in the two tunnels. Pouring supports at the ends of the tube screen to fix both ends of the tube screen; wher...

Abstract

The invention belongs to the technical field of underground tunneling engineering, particularly relates to a large-span underground space structure and a construction method thereof, and provides the underground tunneling space structure and the construction method thereof which have a small influence on social environments and effectively, so that the technical problem that construction difficulty of underground space structure engineering is large is effectively solved. The large-span underground space structure is mainly composed of an underground tunnel structure and underground pipe curtain structures, wherein the underground tunnel structure is mainly composed of a plurality of longitudinal going-ahead tunnels excavated by a shield tunneling machine or a tube push bench; the transverse underground pipe curtain structures which are each composed of a plurality of pipe bodies are arranged between the adjacent longitudinal going-ahead tunnels correspondingly, wherein the pipe bodies are arranged by adopting a linear or arched structure; and therefore, excavating and slag tapping efficiency of excavating equipment is greatly improved, the mechanized construction extent of underground engineering is greatly improved, construction efficiency is improved, and safety of underground engineering construction is ensured.

Description

Technical field [0001] The invention belongs to the technical field of underground digging engineering; specifically, it relates to a large-span underground space structure 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 received more and more attention from the country; and in the process of continuing urbanization in China, the rapid concentration of urban population has made land resources particularly scarce. The demand of the entire society for the development and utilization of underground space is becoming more and more prominent; however, the usual method of underground engineering construction is to use a combination of support and open excavation. However, the biggest problem caused by this traditional method is the need to carry out ground The overall excavation not only affects the surrounding environment, but also seriously hind...
