Problems solved by technology

Due to the large slope of this kind of tunnel, general loading and unloading vehicles cannot enter, and the method of sliding down the trolley can only slip the building materials into the bottom of the tunnel working face, and then hoist the building materials to the corresponding position by the hoist, and there are still large construction problems. the inconvenience

Abstract

The invention discloses a circulation traction anchoring system. The circulation traction anchoring system is arranged between a tunnel anchor and a ground platform of a tunnel portal, and a tunnel has a large slope. The circulation traction anchoring system comprises a supporting frame vertically fixed to the ground platform, a load-bearing system and a traction system. The load-bearing system comprises a first winch, a load-bearing cable and a load-bearing pulley, the first winch is fixed on the ground platform, and the load-bearing cable slides around the supporting frame and anchored at the top end of the anchor surface of the tunnel anchor after being released from a reel of the first winch, the load-bearing pulley is arranged on the load-bearing cable in the tunnel, and building materials are hoisted in the load-bearing pulley. The traction system comprises a second winch and a first traction rope, wherein the second winch is fixed on the ground platform, and the first traction rope slides around the supporting frame after being released from a reel of the second winch and then fixed on the load-bearing pulley. Based on the principle of variable sag cable crane, the circulation traction anchoring system realizes the installation of the building materials at any point in the vertical and horizontal range of the anchor surface, the construction of the tunnel anchor is greatly facilitated, and the construction cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of suspension bridge tunnel anchor construction. More specifically, the present invention relates to a cyclic pull-in anchor system. Background technique [0002] Suspension bridges are one of the main forms of super-long span bridges. Except for the two cable-stayed bridges, Sutong Bridge and Stonecutters Bridge in Hong Kong, all suspension bridges with a span of more than 1000m are all suspension bridges. Due to the structural characteristics of suspension bridges, more and more suspension bridges have begun to be constructed, and the Jinan Jinsha River Bridge is one of the suspension bridges currently under construction. The anchoring of the main cable of Jin'an Jinsha River Bridge adopts the common tunnel anchor form. Due to the large slope of this kind of tunnel, the general loading and unloading vehicles cannot enter. The method of sliding trolley can only slip the building materials under the tunnel work...
