Embodiment

[0048] Please refer to the construction method of straddle monorail track beam installation figure 1 , figure 2 , image 3 , Figure 4 , Including the following steps:

[0049] 1) Rail beam hoisting: platform construction → pier column construction → cap beam construction → support erection → track beam transportation in place → installation of stabilizing hoop, hoisting hoop → installation of temporary supports and permanent supports → hoisting → installation of temporary fixing devices → Loosen the sling

[0050] In the construction steps of the cap, the periphery of the cap 1 is backfilled with C15 concrete 11 and the C30 concrete 12 is hardened, and the top of the cap 1 and the embedded support iron plate 42 on the periphery of the cap 1 are used as the support foundation;

[0051] In the bracket erection step, the steel pipe column is used for support. First, the bottom end of the steel pipe 41 is welded to the embedded support iron plate 42, and then the scissors brace 43 is ...

Abstract

The invention provides a construction method of straddle-type monorail track beams, comprising the steps of 1) hoisting track beams, to be specific, constructing a cap, constructing pier posts, constructing cap beams, setting up supports, transporting the track beams in position, mounting stabilizer hoops and hoist hoops, mounting temporary bearings and permanent bearings, hoisting, mounting temporary fixtures, and loosening hoist ropes; 2) mounting the track beams, to be specific, adjusting line shape of the track beams, welding post-cast segment steel plates, constructing a post-cast segment, casting fulcrum crosspieces between the track beams of left and right lines, constructing mid-span cross tie beams, and removing the temporary fixtures, the temporary bearings and the supports. Theconstruction method enables the problem to be solved that fulcrums, temporary supports, temporary fixations and linear adjustments are difficult during track beam hoisting, is adaptive to setup and mounting of track beams of different specifications and track beams at complex terrains, and has low construction safety risk.

Description

Technical field [0001] The invention belongs to the technical field of track beam construction, and specifically relates to a construction method for the installation of straddle-type monorail track beams. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that requires operating vehicles to travel on specific tracks, such as a railway transportation system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has shown more and more types, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. [0003] Straddle monorail transportation is a medium-volume rail transportation system. It has the advantages of low noise, strong climbing ability, small turning radius, fast and convenient, small area, low cost, and environmental protection. It is a modern urban rapid rail three-dimensional transportation I...
