Embodiment Construction
[0021] In order to further illustrate the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but they should not be construed as limiting the protection scope of the present invention.
[0022] The confluence regulation and storage type deep tunnel constructed by the double-circle overlapping shield machine, such as figure 1 Shown:
[0023] The confluence regulation and storage deep tunnel constructed by the double-circle lap-shaped shield machine is excavated and lined by the double-circle lap-shaped shield machine. The overall layout and spatial layout of the cross section are axisymmetric with the intersection line; Shaped deep tunnel bulkhead 1 is a double-circle lap-shaped section, that is, two circles with equal diameters intersect, and the height of the intersecting line is 0.6 to 0.8 of the circle diameter, forming a double-circle lap-shaped deep tunnel cabin 15 inside; The left and...

A confluence regulation and storage type deep tunnel constructed through a double-circle lap-joint type shield machine is excavated through the double-circle lap-joint type shield machine and formed in a lining mode. The bin wall of the double-circle type deep tunnel has a double-circle lap-joint type section. The overall arrangement of the cross section and spatial layout are in axial symmetry with the intersecting secant line as the axis. A rainwater sub-bin and a sewage sub-bin are arranged on two sides correspondingly and each internally provided with a water bin abutment, and a bottom pedestrian overhaul platform is arranged between the two adjacent water bin abutments. A square-like rainwater pipeline and a square-like sewage pipeline are both in a square-like shape. The confluence regulation and storage type deep tunnel constructed through the double-circle lap-joint type shield machine has the beneficial effects that rainwater and sewage are effectively separated, water pollution is prevented to the maximum extent, an efficient, reliable and safe repair system and repair space are guaranteed, and the space utilization rate is improved.
Description
technical field [0001] The invention belongs to the technical field of deep tunnels, and in particular relates to a confluence regulation and storage type deep tunnel constructed by a double-circle overlapping shield machine. Background technique [0002] Deep storage tunnels refer to large and extra-large drainage tunnels buried in deep underground spaces (generally referring to spaces with a depth greater than 20m below the ground). Generally, in areas prone to waterlogging, densely populated, complex underground pipelines, and difficult to transform existing drainage systems, deep storage tunnels can be set up. The use of large-scale deep storage tunnels supplemented by source runoff control is to implement the construction requirements of the "sponge city" and reflect the water control strategy that is tailored to water conditions and local conditions. It is also a common practice in foreign countries to improve drainage and waterlogging prevention standards in establish...
