Problems solved by technology

However, as the construction quality standard is getting higher and higher, the tunnel lining uses a hydraulic formwork trolley for concrete pouring construction, but due to the limitation of the section shape of the tunnel design lining, it is necessary to design a lining trolley for each section, so the project cost is too high , the construction cost is too high

Abstract

The invention relates to the technical field of tunnel construction, in particular to a small-section chamber lining hydraulic formwork trolley and a construction method. The small-section chamber lining hydraulic formwork trolley comprises formworks, a supporting frame and a translation component, the formworks comprise the first formwork and the second formwork, and the first formwork is used for making contact with the top of a tunnel. The second formworks are used for making contact with the side wall of the tunnel, the second formworks are connected to the two sides of the first formwork and hinged to the first formwork, the connecting angle of the second formworks and the first formwork can be adjusted conveniently, and the tunnel formwork is suitable for tunnels with different sections. The supporting frame is connected with the first formwork and used for supporting the first formwork. The translation component is located at the bottom of the supporting frame, the lifting component is arranged between the translation component and the supporting frame, longitudinal positioning of the trolley can be adjusted through lifting of the lifting component, after concrete on the inner wall of a tunnel is solidified, demolding can be facilitated by lowering the lifting component, and one set of trolley can be suitable for various tunnels with different sections and different gradients. The construction cost is reduced.

Description

technical field [0001] The disclosure relates to the technical field of tunnel construction, in particular to a small-section chamber lining hydraulic formwork trolley and a construction method. Background technique [0002] Most of the pedestrian tunnel linings in long tunnels are constructed using combined wooden formwork and I-steel platform support structures for pouring construction. The construction process is cumbersome and the quality control is poor. Furthermore, a self-made lining trolley was developed, and the use of the lining trolley speeds up the construction progress, greatly improves the construction quality, and has the characteristics of significant economic benefits. However, as the construction quality standard is getting higher and higher, the tunnel lining uses a hydraulic formwork trolley for concrete pouring construction, but due to the limitation of the section shape of the tunnel design lining, it is necessary to design a lining trolley for each sec...
