Problems solved by technology
For the construction method of "arch the wall first and then the inverted arch", nowadays, the conventional inverted arch concrete lining of the tunnel is constructed by the inverted arch trolley. Considering the construction plan, the traditional inverted arch steel formwork trolley is restricted by the demoulding time , the construction speed is not easy to increase, and the production cost of the inverted arch trolley is high, which increases the construction cost

Embodiment Construction
[0026] The present invention will be further described in detail below with reference to the drawings and examples, but the present invention is not limited to the following embodiments.
[0027] exist figure 1 , 2 Among them, the tunnel invert concrete lining sliding form in this embodiment is composed of a left supplementary hopper 2, a guard plate 1, a reinforcing rib 3, a hoist 4, a sliding formwork 5, a right supplementary hopper 6, and a plate vibrator 7. For further understanding, define the forward direction of the sliding model as the front side.
[0028] A guard plate 1 perpendicular to the slide formwork 5 is arranged around the slide formwork 5, the slide formwork 5 and the guard plate 1 are connected as a whole, and criss-cross reinforcement ribs 3 are welded on the slide formwork formwork 5, and the reinforcement ribs 3 prevent sliding The mold template 5 is deformed, and the geometric shape of the sliding formwork 5 is the same as that of the tunnel invert. Th...

The invention provides a tunnel inverted arch concrete lining slip form and a construction method. Guard boards perpendicular to a formwork of the slip form are arranged on the periphery of the formwork of the slip form and connected with the formwork of the slip form into a whole. Reinforcing ribs are arranged on the formwork of the slip form. The geometrical shape of the formwork of the slip form is the same as the shape of a tunnel inverted arch. A left material supplementation hopper is arranged on the left side of the formwork of the slip form in a penetrating mode, and a right material supplementation hopper is arranged on the right side of the formwork of the slip form in a penetrating mode. The formwork of the slip form is provided with a winch and a flat plate vibrator. The construction method of the tunnel inverted arch concrete lining slip form comprises the steps of leveling treatment of a slip form slide rail part, slip form positioning, connection of a slip form slide power device, concrete pouring and manual precise leveling of a concrete surface.
Description
technical field [0001] The invention belongs to the technical field of tunnel lining, and in particular relates to a tunnel inverted arch concrete lining sliding form and a construction method. Background technique [0002] In recent years, with the continuous advancement of my country's scientific and technological strength, the continuous innovation of construction equipment in the construction industry, and the continuous improvement of technological levels, the water diversion tunnels in water conservancy and hydropower projects have gradually developed in the direction of super long and super large diameters. There are two types: "arch the wall first and then arch the wall" and "arch the wall first and then arch the wall". For the construction method of "arch the wall first and then the inverted arch", nowadays, the conventional inverted arch concrete lining of the tunnel is constructed by the inverted arch trolley. Considering the construction plan, the traditional inve...
