Abstract
The invention discloses a power transmission project prefabricated foundation installation and iron tower assembly coherent construction method which includes the following steps of re-measurement andpit dividing, construction plane design, ground tower assembly, foundation pit excavation, foundation backfill, process changing acceptance and overall tower erection. Through the technical scheme, aconstruction process of "foundation construction first, then tower assembly on the ground" in the prior art is adjusted to " tower assembly first, then foundation construction", the on-site development of a flow process mode of "personnel flow with machinery, continuous machinery operation and process close connection" is facilitated, the close connection of ten processes of "on-site re-measurement, pit dividing positioning, construction plane design, ground tower assembly, foundation pit excavation, prefabricated foundation transportation and installation, grounding installation, foundationbackfilling and compaction, process changing acceptance and overall tower erection" can be realized, the overall construction efficiency of the line foundation and the iron group assembly is improved,the construction period is shortened and controllable, the fully mechanized construction of the line engineering is realized, the economic benefits are significant, and the safety risks are reduced.
Description
Technical field [0001] The invention relates to the technical field of power transmission, in particular to a continuous construction method for prefabricated foundation installation and iron tower assembly of power transmission projects. Background technique [0002] The traditional construction process of power transmission project foundation and pole tower is: ①Re-measurement of sub-pit→②Excavation of foundation pit→③Tie bar of foundation→④Foundation support form→⑤Concrete pouring→⑥Foundation demoulding→⑦Backfill of foundation pit→⑧Foundation Maintenance→⑨Tower material transportation→⑩Ground tower assembly→ Crane tower. Among them, the foundation construction period (①→⑧), especially the foundation maintenance time is too long (the winter construction maintenance cycle is longer), which leads to the increase of the overall construction period and higher construction costs. [0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned sh...
