Construction method of full-circle inclined shaft steel bar rapid positioning and binding trolley

Abstract

The invention discloses a construction method of a full-circle inclined shaft steel bar rapid positioning and binding trolley. The invention solves the following problems: construction labor intensityis high, annular steel bars perpendicular to the axis are difficult to ensure, steel bar positioning is difficult, construction quality precision is difficult to ensure and construction efficiency islow. The full-circle inclined shaft steel bar rapid positioning and binding trolley is adopted as a force bearing jig frame of each layer of steel bar net, outer layer steel bar binding is completedfirstly, and then inner layer steel bar binding is completed. Each layer of reinforcing steel bars is accurately fixed in place by adopting circumferential reinforcing steel bars, and then the longitudinal reinforcing steel bars are accurately positioned and bound. After the steel bars are bound into a whole, the steel bars and the bed rock are tied, supported and fixed. According to the construction method, while accurate positioning and binding of the steel bars are achieved, the labor intensity is reduced, and the construction precision and efficiency are improved.

Description

technical field [0001] The invention relates to a construction method for 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. Contents of the invention [0003] The object of t...
