Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The immersed tube of the seabed tunnel precast construction that large scale, life requirement are high is generally: be highly about 1200cm, width is about 3800cm, and length is about 2300cm, and it generally should have following condition:
(1) tunnel immersed tube is used for seabed or is embedded in underground, driving passage is positioned at inside tube coupling (instead of traditional case beam form, be positioned at upside), the cross dimension of tube coupling will become larger than the case beam size of routine; (2) length of tube coupling is also unsuitable too short because the length of tube coupling more short circuit head quantity will more, difficulty increase (mainly joint patching) of joint process, the risk of existence is also higher; (3) seabed tunnel life requirement is high, does not allow to occur cold seam and constuction joint etc., must one-time cast-forming.
The present invention possesses above-mentioned condition to make the tunnel immersed tube after pouring into a mould, and provides a kind of immersed tube pouring procedure, immersed tube skeleton A is divided into baseplate zone A1, top panel area A4, two side wall region A2 and two middle wall zone A3 carry out pouring into a mould by different level.
