Method for predicting temporary occupied area of mechanical construction tower footing area in hilly region
The invention relates to a method for predicting the temporary occupied area of a tower footing area in mechanical construction in a hilly area, and belongs to the technical field of power construction methods. According to the technical scheme, a high-low leg tower footing of a single-side slope is used as a research object, residual soil generated by field leveling of each tower leg before foundation excavation and earthwork excavated by a mechanical construction rotary drilling rig and the like are used as main measurement and calculation objects, a half-excavation and half-filling mode is adopted for construction channels, earthwork self-balancing is not calculated, and the construction efficiency is improved. Other excavation residual soil is stacked along the boundary of the construction channel, area prediction is conducted according to the situation that residual soil stacking measures are strictly executed, the residual soil with the small terrain gradient is stacked along the slope, and blocking measures are taken on the outer slope surfaces of the tower legs with the large terrain gradient. The method has the beneficial effects that the method for accurately predicting the disturbance area of the single tower footing is realized aiming at the tower footing of the typical single-side slope surface in the hilly area by combining the characteristics of a power transmission and transformation project.
本发明涉及一种山丘区机械化施工塔基区临时占地面积预测的方法，属于电力施工方法技术领域。本发明的技术方案是：以单侧坡面的高低腿塔基为研究对象，以基础开挖前每个塔腿的场地平整产生的余土和机械化施工旋挖钻机等挖出的土方作为主要测算对象，施工通道均采用半挖半填的方式，土方自平衡不作计算，其他的开挖余土均沿着施工通道边际堆放，按照较为严格执行余土堆放措施的情形进行面积预测，其中地形坡度小的顺坡堆放，坡度较大的塔腿外坡面采取拦挡措施。本发明的有益效果是：结合输变电工程特点，针对山丘区典型单侧坡面的塔基，实现单塔基扰动面积较为准确的预测方法。
