Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0045] A suspended and overturned tunnel inverted arch formwork trolley, which includes an inverted arch formwork 1, and also includes a formwork entry and exit system, a formwork adjustment system, and a walking support frame 3 for supporting the overall weight;

[0046] The entry and exit system of the formwork includes: a chain hoist or an oil cylinder 17, a formwork turning hinge ear beam 8, a formwork connecting beam 5 installed on the inverted arch formwork 1, and the entry and exit system mainly plays a role in the closing state of the present invention. When the mold is retracted, the inverted arch formwork is separated from the filling top surface by a certain height, so that there is room for manual plastering during concrete filling construction;

[0047] The template adjustment system includes: a supporting screw 2, the template connecting beam 5, an adjusting scr...

Abstract

The invention relates to the technical field of tunnel secondary lining, and particularly discloses a suspension overturn type tunnel inverted arch formwork trolley. The suspension overturn type tunnel inverted arch formwork trolley comprises an inverted arch arc-shaped formwork, a formwork folding and supporting system, a formwork adjusting system and a walking support frame. The formwork folding and supporting system has the function of making the inverted arch formwork leave a padding top surface by a certain height under a certain working condition, so that a space for manual plastering is available at the time of concrete padding construction; the formwork adjusting system has the function of adjusting the position and the height of the inverted arch arc-shaped formwork so as to meet different requirements. At the time of tunnel inverted arch construction and the padding construction, the suspension overturn type tunnel inverted arch formwork trolley is convenient and fast to use, capable of improving the construction efficiency, high in reliability, and low in construction cost. The invention further discloses a construction method of the suspension overturn type tunnel inverted arch formwork trolley. The utilization of the construction method enables the suspension overturn type tunnel inverted arch formwork trolley to meet different working conditions and greatly increases the use value of the suspension overturn type tunnel inverted arch formwork trolley.

Description

technical field [0001] The invention relates to the technical field of secondary lining of tunnels, in particular to a suspended and overturned tunnel inverted arch formwork trolley with adjustable position and height of an inverted arch formwork and a construction method thereof. Background technique [0002] There are many construction methods used in tunnel inverted arch concrete construction: simple arc-shaped assembled formwork, self-hanging inverted arch mobile formwork, and a formwork construction system that integrates inverted arch formwork and inverted arch trestle. [0003] The simple arc-shaped assembled formwork is composed of several arc-shaped formworks with a length of 1.5 meters. It needs to be installed on site, which is not only labor-intensive, but also the quality of concrete construction is poor. [0004] The self-hanging inverted arch mobile formwork requires special laying of tracks and requires the cooperation of an excavator for installation. The in...
