Reverse construction method for pipe-jacking bricked working well
The invention discloses a reverse construction method for a pipe-jacking bricked working well. The method comprises the following steps of 1) determining the wall thickness of the well; 2) carrying out measuring, paying off and positioning; 3) carrying out earth excavation; 4) building a well chamber; 5) carrying out well bottom construction; 6) pouring a well chamber inner side protection wall; and 7) backfilling the well chamber, wherein in the step 3) and the step 4), earth excavation, well wall building and reinforced concrete ring beam pouring are conducted layer by layer from top to bottom, after construction of the upper layer is completed, construction of the next layer is conducted till all building work of the well chamber is completed, and steel bars of a lower-layer ring beam need to be pre-buried when the upper-layer well wall is built. When the well wall is built, the method for controlling the diameter of the well chamber comprises the steps that after the first layer ofwell chamber is excavated, part of the wall body is built firstly, then two steel pipes are crossed to form a cross shape, and the steel pipes are hung down from the center of the well chamber and fixed to the built wall body; and plumb bobs are tied to the two ends of each steel pipe, the distance between the paired plumb bobs corresponds to the inner diameter of the well chamber, and the plumbbobs and plumb bob lines are used as references for a bricklayer during bricklaying.
一种顶管砖砌工作井逆作法施工方法，步骤包括：1)确定井壁厚度；2)测量、放线、定位；3)土方开挖；4)井室砌筑；5)井底施工；6)井室内侧护壁浇筑和7)井室回填；步骤3)和步骤4)中：自上而下逐层进行土方开挖、井壁砌筑和浇筑钢筋混凝土的圈梁，当上面一层施工结束后，再进行下一层施工，直到完成全部井室砌筑；在上层井壁砌筑时候要预埋下层圈梁的钢筋。在井壁砌筑时，控制井室直径的方法为：在第一层井室开挖后，先砌筑部分墙体，再用两根钢管交叉形成十字状，由井室中心位置吊下，并固定于已经砌筑好的墙体；再在每根钢管的两端系上铅锤，成对铅锤之间的距离与井室内径对应，铅锤以及铅锤线用于瓦工在砌筑时作为参考。
