Description
SUNPT18150WOLU LU101102 Machine Non-Excavation Advancing Apparatus
[0001] Embodiments of the present disclosure generally relate to the field of tunnel construction technologies, and more particularly relate to a shield machine non-excavation advancing apparatus.
[0002] More and more subways have been constructed with city development. Urban subway construction generally adopts shallow-buried bored tunnels. The tunnel lines always pass through downtowns, where crowded buildings are erected above the tunnels, the lines go through many pipelines, the ground surface is densely populated, and the traffic is heavy. To alleviate the impacts of tunnel construction on the ground surface and to control subsidence of the ground surface, subway tunnel construction generally adopts shield tunneling. However, in case of a complex geology, other construction method is needed for tunneling, and when a shield machine advances to an excavated tunnel, the shield machine needs to advance through the excavated segment without excavation.
[0003] The Chinese patent CN106150511B discloses a construction method of shield tunneling-type non-excavation advancing through an earth fissure bored tunnel, comprising steps of: 1. constructing a concrete guide platform in an earth fissure bored tunnel; 2. constructing a guide rail and a reaction frame; 3. pushtowing the whole shield machine forward: pushtowing the shield machine forward and causing the shield body to be propped on two guide rails, and then pushtowing the propulsion oil cylinder of the shield machine and the reaction frame forward as a whole till in place; during the pushtowing process, a plurality of shield duct pieces are mounted on the concrete guide platform from the rear to the front using a shield duct piece erector of the shield machine, wherein the shield duct pieces are bottom duct pieces and disposed at a rear side of the propulsion oil cylinder, the propulsion oil cylinder being propped on the reaction force through the bottom duct pieces; a plurality of bottom duct pieces form a bogie translational passage for a rear ancillary bogie to translate forwardly; this method implements a construction process of shield non-excavation advancing through the earth fissure bored tunnel using an in-tunnel inverted arch backfill structure. However, the shield machine guide platform is generally made of reinforced concrete. The thickness of the guide platform and the reinforcement quantity of steel bars are dependent on 1
SUNPT18150WOLU LU101102 the advancement space height of the shield machine and the required reaction force needed for advancing the shield machine. If the non-excavation segment tunnel space has a limited height while the thickness of the concrete guide platform needs to be reduced in design, such problems easily arise: insufficient guide platform thickness; insufficient depth of the reaction holes on the guide platform; small contact area between the reaction holes and the reaction frame such hat the stress is easily concentrated, which is prone to cause damages to the guide platform concrete surrounding the holes. If the reaction force is insufficient, it is hard to advance the shield machine. If the shield machine has enough space at the non-excavation advancing segment, thickening of the concrete guide platform may guarantee a sufficient reaction force to the shield machine while avoiding or reducing damages to the concrete guide platform, which, however, will inevitably increase the amount of concrete and steel bars in use, thereby increasing economic costs.
