Formation and construction set for continuous open-cut tunnel

Abstract

The invention discloses a formation and construction set for a continuous open-cut tunnel. The formation and construction set comprises a frame; the frame comprises two gantries; the gantries are connected together through a vertical beam; the vertical beam is connected with a formwork through a mechanical support; telescopic posts and travelling mechanisms are provided below the gantries. The formwork comprises a plurality of groups of tunnel arc forms vertically spliced; the tunnel arc forms in each group are in integrated large form structures, the tops of which fit the sectional shape of the tunnel; an arc slurry-lifting and leveling unit is arranged at the top of the tunnel arc forms. The formation and construction set is suitable for lining construction by a wall-first and arch-second method; the designed lining is suitable for use in highways, diversion tunnels, railway tunnels and the like, with less than 600mm of thickness. The formation and construction set is simple in structure and attractive in style, allows convenience for construction, and is of good integrity, high automation level, high form removal speed and high in-position speed.

Description

technical field [0001] The invention relates to a tunnel construction technology, in particular to a continuous open hole tunnel forming construction device. Background technique [0002] In the past few years, the open hole construction encountered in my country's high-speed railway construction was carried out using outdated construction equipment and methods. The formwork was supported by simple steel bar lapping and steel structure welding, and the formwork used for construction was all small. Formwork construction, this method brings many problems. First, the use of small formwork construction has poor integrity, cracks, and poor waterproof performance. Second, the formwork removal process is complicated, construction efficiency is low, and labor costs are high. [0003] At the same time, in the previous open-hole construction, the top of the formwork was manually tamped and plastered, which resulted in a low degree of mechanization, low construction efficiency, and high...
