Embodiment

[0031] A method for assembling a bridge building machine at the exit of a tunnel connected by bridges and tunnels, comprising the following steps:

[0032] (1) Reserve the work site on the left and right sides of the 0# platform and the 1# pier and roll it flat. The range is about 10 meters wide on the left and right sides of the center line of the 0# platform and the 1# pier. Use mortar to level the bearing action point on the top of 1# pier;

[0033] (2) Install the slipping traveling wheel set at the bottom of the main beam of the second section and the main beam of the third section;

[0034] (3) Install the electric running motor mechanism of the rear outrigger of the first section of the main beam of the bridge building machine at the bottom of the inverted arch of the tunnel, install the front outrigger on the 0# platform, and use the car to lift the first section of the main beam and place it on the rear outrigger electric motor mechanism On the front outriggers of...

Abstract

The invention discloses the field of bridge construction, and particularly relates to an assembly method of a bridge-building machine at an exit of a tunnel connected with a bridge. The assembly method of the bridge-building machine mainly comprises the following steps of: setting aside a working site; installing sliding devices at the bottoms of a second main beam and a third main beam; installing an electric running mechanism for a rear support leg of a first main beam of the bridge-building machine at the bottoms of an inverted arch of the tunnel, and installing a front support leg on a No. 0 platform; assembling the main beams and guide beams through a running motor in the electric running mechanism for the rear support leg, and returning into the tunnel; and moving the whole assembled structure of the main beams and the guide beams out of the tunnel through the running motor in the electric running mechanism for the rear support leg. By adopting the assembly method, large-scale backfilling, flattening and hardening are not needed for an assembly site, large quantities of earthwork and stonework engineering and shifts for operation of large-tonnage lifting devices can be saved, and the installation period can be greatly shortened.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a method for assembling a bridge-building machine at the exit of a tunnel connected by bridges and tunnels. Background technique [0002] The MZ32 bridge building machine is generally installed at the initial span of construction. The manufacturer provides two options for on-site installation: 1. The traditional frame installation method, when the pier is not high (generally less than 20m in height), it can be directly on site according to the order of formwork support force, from bottom to top Step by step installation, only need to level the site, use 50T crane for installation. 2. The overall installation method, when the pier is high (greater than 20m), the whole machine lifting method is adopted. Assembled site requirements, within the initial pier span, the site area often needs to be 60m long and 30m wide and wide and flat without debris, and necessary temporary frames...
