Construction method for reinforcing tower crane foundation through foundation expansion method
The invention relates to a construction method for reinforcing a tower crane foundation through a foundation expansion method. The construction method comprises the following steps that S1, four materials including steel bars, concrete, anchoring steel bars and cement mortar are prepared; s2, the outer surface of the original tower crane foundation is coated with a layer of cement mortar; s3, holes are formed in the outer surface of the original tower crane foundation through an anchor rod drilling machine technology, and anchoring steel bars are placed in all the holes; s4, cement mortar is injected into the holes through a grouting machine; s5, reinforcing steel bars are used for binding and building a reinforcing steel bar frame on the periphery of the original tower crane foundation; s6, a cushion layer is laid on the foundation at the bottom of the steel bar frame; s7, a formwork is supported on the periphery of the steel bar frame, and concrete pouring is conducted to form a reinforced and enlarged foundation; and S8, after the concrete is solidified, the tower crane foundation reinforcement work is completed. The original tower crane foundation is reinforced by utilizing a foundation expansion method, so that the cost of dismantling, moving and the like is reduced, the engineering cost is saved, and the engineering period is shortened.
本发明涉及一种通过基础扩大法加固塔吊基础的施工方法，包括以下步骤：S1:准备钢筋、混凝土、锚固钢筋、水泥砂浆4种材料；S2:在原塔吊基础的外表面涂上一层水泥砂浆；S3:在原塔吊基础的外表面利用锚杆钻机技术进行成孔，并在各孔内放入锚固钢筋；S4:通过注浆机向孔内注入水泥砂浆；S5:利用钢筋在原塔吊基础的外围绑扎搭建钢筋框架；S6:在钢筋框架底部的地基上铺设垫层；S7:在钢筋框架的外围支护模板并进行混凝土浇筑形成加固扩大基础；S8:待混凝土凝固后塔吊基础加固工作完成。本发明利用基础扩大法对原塔吊基础进行加固，减少了拆除和动迁等费用，节约了工程成本，缩短了工程工期。
