Ground surface anti-settlement construction method for helicopter apron
The invention discloses an earth surface anti-settlement construction method for a helicopter apron, which comprises the following steps: S1, pouring a concrete layer: firstly, arranging and leveling the surface of a soft soil foundation, then paving concrete on the surface, and then pouring a prefabricated steel bar net rack and a prefabricated steel bar pipe to form a steel bar concrete layer; s2, a compensation layer is laid, specifically, a first quick lime layer and a second quick lime layer are laid on the reinforced concrete layer treated in the S1 stage from bottom to top. According to the ground surface anti-settlement construction method for the helicopter apron, when the phenomenon of uneven settlement occurs, a worker can pointedly inject water into the first quicklime layer at the settlement position through the water injection pipe according to the settlement position, so that the settled helicopter apron can be compensated; and meanwhile, the groove poured in the S1 stage can play a role in limiting the expansion direction of the second layer of quick lime and the first layer of quick lime, it is guaranteed that upward expansion of the groove compensates for the settlement distance, and therefore the service life of the helicopter apron is prolonged.
本发明公开了一种用于直升机机坪的地表防沉降施工方法，包括S1：浇筑混凝层：首先整理平整软土地基表面，然后在上面铺设混凝土，紧接着将预制好的钢筋网架和钢筋管进行浇注，形成钢筋混凝层；S2：铺设补偿层：接着将S1阶段处理后的钢筋混凝层上从下至上分别铺设第一生石灰层和第二生石灰层。该用于直升机机坪的地表防沉降施工方法，当出现不均匀沉降的现象时，工作人员可根据沉降位置有针对性的通过注水管向该处的第一生石灰层内注水，从而即可对发生沉降的直升机机坪进行补偿，同时S1阶段的浇筑的槽可起到限制第二层生石灰和第一生石灰层膨胀方向的作用，保证其向上膨胀对沉降距离进行补偿，并以此延长直升机机坪的使用寿命。
