Embodiment Construction

[0037] A fast positioning and binding trolley for steel bars in a full-circle inclined shaft will be described in detail in conjunction with the accompanying drawings.

[0038] The present invention mainly realizes from the following aspects:

[0039] A trolley for quickly positioning and binding steel bars in a full-circle inclined shaft includes a frame beam 1, a regular polygonal ring beam 2, an adjusting screw 3, a circumferential steel bar positioning device 4, a longitudinal steel bar positioning plate, an operating platform 6, and a top stacking platform 7, Road wheel system 8, traction system 9.

[0040] The operation platform 6 is arranged around the frame beam 1, two are arranged on each floor. The operation platform is a retractable structure, which meets the requirements for the binding construction of inner and outer layers of steel bars. The platform is designed as an adjustable structure, and the top stacking platform 7 is fixed on the front end of the frame bea...

Abstract

The invention relates to a construction method for rapid positioning and binding of steel bars in a full-circle inclined shaft. It solves the problems of high construction labor intensity, difficulty in ensuring that the circumferential steel bars are perpendicular to the axis, difficult in positioning the steel bars, difficult to ensure the accuracy of construction quality, and low in construction efficiency. The invention adopts a full-circle inclined shaft steel bar binding trolley as the load-bearing tire frame of each layer of steel mesh, and first completes the binding of the outer layer of steel bars, and then completes the binding of the inner layer of steel bars. Each layer of reinforcement is firstly fixed in place by the circumferential reinforcement, and then the longitudinal reinforcement is precisely positioned and bound. After the steel bars are bound into a whole layer, the steel bars of this layer are tied to the bedrock for support and fixation. This construction method realizes precise positioning and binding of steel bars, while reducing labor intensity and improving construction accuracy and efficiency.

Description

technical field [0001] The invention relates to a construction method for quickly positioning and binding steel bars in a full-circle inclined shaft of a diversion tunnel of a hydropower project. Background technique [0002] The second-lined concrete structural reinforcement of the inclined straight section of the water diversion tunnel of the hydropower project is designed as two layers of inner and outer layers. The arc reinforcement is perpendicular to the axis of the tunnel, and the longitudinal reinforcement is parallel to the axis of the tunnel and distributed evenly along the circumference. On site, scaffolding is often erected from bottom to top as a support for binding steel bars. This kind of construction is labor-intensive, and it is difficult to ensure that the circumferential steel bars are perpendicular to the axis, difficult to position steel bars, difficult to ensure construction quality accuracy, and low construction efficiency.
