The invention discloses a metro shield construction general segment assembling point location determining method. A shield tunneling machine is used for conducting shield tunneling construction on a construction tunnel along a tunnel central axis from back to front. After the shield tunneling construction is completed for one link, shield segment assembling construction is carried out. Before anylink of shield segment assembling construction is performed, first of all, segment assembling point locations of current shield segments are determined. Processes include the following steps that firstly, selectable assembling point locations are determined; secondly, selection influence indexes and weight coefficients of the selection influence indexes are determined, and the three selection influence indexes and the weight coefficients of the three selection influence indexes influencing segment assembling point location selection are determined separately; thirdly, the selectable assemblingpoint locations are selectively evaluated, wherein according to a weight coefficient method, the selection of all the selectable assembling point locations is evaluated separately, and the segment assembling point locations of the current shield segments are determined. The shield general segment assembling point location determining method is simple in step reasonable in design, convenient to achieve, good in using effect and capable of conveniently, fast and precisely determining the assembling point locations of the general segments.

The invention provides full-automatic profile stacking equipment. The full-automatic profile stacking equipment is characterized in that a support, stacking units and a feeding unit are included; the stacking units on the two sides each comprise a bearing mechanism, a lifting mechanism, a lifting drive module and a turnover module; the positions of the bearing mechanisms on the two sides are opposite, and a distance is reserved between the bearing mechanisms on the two sides so that the bearing mechanisms on the two sides can bear the two ends of each profile correspondingly; the bearing mechanisms on the two sides are connected with the lifting mechanisms on the two sides through the turnover modules on the two sides correspondingly so that the bearing mechanisms on the two sides can be turned over downwards to enable the profiles to slide into a stacking area; and the lifting mechanisms on the two sides are arranged on the support through the lifting drive modules on the two sides, so that the lifting mechanisms on the two sides ascend and descend. According to the stacking equipment, the labor cost can be reduced, the profiles are stacked in order, the storage space is saved, the stacking efficiency is high, and the product quality is improved. The invention further provides a full-automatic profile stacking method. According to the full-automatic profile stacking method, the labor cost is reduced, the profiles can be stacked in order, the storage space is saved, the stacking efficiency is high, and the product quality is improved.
