Integrated quick moving formwork for tunnel multi-longitudinal cable trough construction

Abstract

The invention relates to an integrated quick moving formwork for tunnel multi-longitudinal cable trough construction. The formwork comprises at least two beams which are horizontally arranged, and an outer support and an inner support which are parallel to each other, wherein the outer support is of a frame structure and comprises a first outer longitudinal beam which is horizontally arranged, a second outer longitudinal beam is arranged below the first outer longitudinal beam and parallel to the first outer longitudinal beam, the first and second outer longitudinal beams are connected with each other through ground jacks which are vertically arranged, and rollers are arranged on the bottoms of the ground jacks; the inner support comprises an inner longitudinal beam which is horizontally arranged, the two ends of the inner longitudinal beam are respectively connected with two stand columns, the upper ends of the stand columns are fixedly connected with the inner longitudinal beam, and the rollers are also arranged on the bottoms of the stand columns; the beams are vertical to the first outer longitudinal beam and the inner longitudinal beam, one ends of the beams are connected with the first outer longitudinal beam through bolts, and the middle parts of the beams are connected with the inner longitudinal beam through the bolts; and a form board is suspended below the beams through a lead ejector rod, the upper part of the lead ejector rod is connected with the beams through nuts, and the lower end of the lead ejector rod is connected with the form board through nuts.

Description

technical field [0001] The invention relates to a tunnel ditch and cable trough construction device, in particular to an overall fast-moving formwork for tunnel multi-longitudinal cable trough construction, which belongs to the field of tunnel construction. Background technique [0002] In railway tunnels, it is usually necessary to set multiple longitudinal grooves along both sides of the tunnel, such as figure 1 As shown, grooves such as a water ditch 102 , a power cable groove 103 , and a telecommunication cable groove 104 are provided on the side of the tunnel close to the wall 101 . The formation of these trenches requires the construction of concrete pours. The traditional construction method is to use small combined steel formwork to construct in sections. The construction process includes formwork assembly and reinforcement, concrete pouring, formwork disassembly, and transition to the next cycle of construction. The process is complicated, the cycle time is long, a...

Problems solved by technology

The traditional construction method is to use small combined steel formwork to construct in sections. The construction process includes formwork assembly and reinforcement, concrete pouring, formwork disassembly, and transition to the next cycle of construction. The process is complicated, the cycle time is long, and many reinforcement supports are required. , the integrity is poor, the appearance quality of pouring is difficult to control, and the input cost is also high
