A land rapid transfer method for segmental box girders

Abstract

The invention discloses a method for rapid transfer of segmental box girders on land, which comprises: step 1: setting up a plurality of beam segment portal brackets parallel to each other at a certain distance along the channel direction on the beam transport channel; step 2: placing the completed beam The section is hoisted on the beam section portal bracket by a gantry crane, and each beam section is supported by at least two beam section portal brackets; Step 3: After the beam section portal brackets are all loaded with the beam section , move the lifting beam truck to the bottom of the portal brackets of each beam section, and lift the portal brackets of each beam section off the ground; Step 4: Transport the beam sections to the construction or transfer by lifting the beam truck Destination; Step 5: The self-lifting beam truck places the beam segment gantry bracket at the destination. The invention increases the number of beam sections transported by the beam transport vehicle at one time, effectively reduces the round-trip times of the vehicle and saves time spent on beam section transportation.

Description

Technical field [0001] The present invention relates to a rapid transport method of segment box beam land. Background technique [0002] In recent years, the construction of the bridge will generally use the prefabricated beam section for construction. The construction of the beam section is often far from the distance. It is necessary to transport the preformed beam section transportation to the exemption of the pre-built beam section. There is a channel of transport beam sections outside the prefabricated platform, typically lifting the beam segment into the beam vehicle, transporting it from the land to the frame or water transfer terminal by lifting equipment. In the prior art, the length direction of the beam section is consistent with the length direction of the conveyor platform, so that the beam section is located in the bearing range of the beam platform, so that the temperature of the beam section can be improved, even if the beam segment is transported A little shaking...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for rapid transfer of segmented box girders on land to solve the problems in the prior art that the girder segments are limited at one time, and the girder segments need to be carried by many vehicles and need to spend more time waiting for the vehicles to return.
