Embodiment Construction

[0042] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0043] see figure 1 , because the entire section width of the vault of the emergency stop zone section is one more lane than the normal driving tunnel (normal lane section), the corresponding formwork section vault arc surface needs to be enlarged. Therefore, for these two working conditions (emergency parking zone section and normal lane section), the neutral plane of the trolley formwork does not overlap, and the trolley needs to move to the right as a whole to ensure that the left vault is basically the same.

[0044] In order to facilitate the efficient construction of the emergency stop belt section and the conventional lane section, based on this, the embodiments of the present application provide a formwork adaptive conversion system for lining a trolley.

[0045] see figure 2...

Abstract

According to the formwork self-adaptive conversion system of the lining trolley and the conversion method of the formwork self-adaptive conversion system, the length of the top frame body is adjusted through stretching and retracting of the top frame telescopic hydraulic cylinders arranged on the left side and the right side of the central stand column, and the sub-formworks connected with the formwork lifting hydraulic cylinders are lifted or lowered through stretching and retracting of the formwork lifting hydraulic cylinders; each stand column jacking hydraulic cylinder stretches out and draws back to increase or decrease the height of the tail end of the corresponding top die stand column, each die plate adjusting hydraulic cylinder controls the extending die connected with the die plate adjusting hydraulic cylinder to retract inwards or extend outwards, and when the extending die extends outwards, the tail end of the extending die is located at the tail end of the central stand column and connected with the other extending die in a matched mode. And when the extension mold retracts inwards, the sub-mold connected with the extension mold is located at the tail end of the central stand column and is connected with the other sub-mold in a matched mode, and template retraction of the lining trolley is achieved. Therefore, by means of the formwork self-adaptive transformation system of the lining trolley, the lining trolley can be applied to construction of a conventional lane section and an emergency parking strip section through self-adaptive transformation.

Description

technical field [0001] The present application relates to the technical field of tunnel construction, and in particular, to a formwork adaptive transformation system for a lining trolley and a transformation method thereof. Background technique [0002] When constructing a tunnel, an emergency parking zone needs to be built every 0.5 to 1 km. The entire section width of the vault of the corresponding section is one more lane than that of a normal driving tunnel, and the arc surface of the corresponding formwork section vault needs to be enlarged. [0003] The current conventional construction method is usually to replace the trolley specially used for the vault lining of the emergency parking belt section; or, when the trolley is lined from the normal lane section to the emergency parking belt section, the formwork is removed and the bracket beam is lengthened separately One section, the vertical beam of the bracket is increased by a section, and due to the increase of the a...
