Variable cross-section template and construction method of variable cross-section immersed tube
The invention relates to the technical field of immersed tube construction, in particular to a variable cross-section formwork and a construction method of a variable cross-section immersed tube, the variable cross-section formwork comprises an inner formwork system and an outer formwork system, and the inner formwork system is located in the outer formwork system; the two outer sides of the inner formwork system are provided with first inclined planes which are relatively inclined inwards, the two inner sides of the outer formwork system are provided with second inclined planes which are relatively inclined inwards, and the second inclined planes correspond to the first inclined planes on the same side; and the area between the inner formwork system and the outer formwork system is poured to form the immersed tube. When an immersed tube is poured, an inclined side wall is arranged between the second inclined face and the first inclined face on the same side to form a horn-shaped section of the immersed tube, then lane convergence is achieved through the horn-shaped section of the immersed tube, immersed tube pouring is conducted through the variable cross-section formwork, the immersed tube is provided with the horn-shaped section, the variable cross-section immersed tube is formed, and then the construction requirement is met.
本发明涉及沉管施工技术领域，特别是一种变截面模板及一种变截面沉管的施工方法，变截面模板包括内模板系统和外模板系统，所述内模板系统位于所述外模板系统内部；所述内模板系统的两外侧具有相对向内倾斜的第一斜面，所述外模板系统的两内侧具有相对向内倾斜的第二斜面，所述第二斜面与同侧所述第一斜面相对应；浇筑所述内模板系统与所述外模板系统之间的区域以形成沉管。在浇筑沉管时，从而使第二斜面与同侧第一斜面之间具有倾斜的侧壁，形成沉管的喇叭段，进而使沉管通过喇叭段来实现车道汇流，通过本申请的变截面模板来进行沉管浇筑，使沉管具有喇叭段，形成变截面沉管，进而满足施工需求。
