Underground pile connecting wall for shallow foundation pit support structure and construction method of underground pile connecting wall
The invention discloses an underground connecting pile wall for a shallow foundation pit support structure and a construction method of the underground connecting pile wall. The construction method comprises the following steps that S1, a guide wall is constructed along the periphery of a foundation pit; according to the construction method, continuous grooving is conducted on the outer side of the foundation pit of the accessory structure of the subway station, in the grooving process, the perpendicularity of a groove section can be observed in real time through an instrument panel of the grooving machine, correction is conducted in time, and the grooving perpendicularity is high; after grooving is finished, perpendicularity detection is conducted through ultrasonic waves, and guarantee is provided for installation of the reinforcement cage; the groove sections are engaged through the lock catch pipe joints, the wall of the joints is brushed before the reinforcement cage is installed on the subsequent groove sections, and the anti-seepage effect of the joints is good; the reinforcement cages are square or round, the weight is light, hoisting is convenient, a plurality of reinforcement cages are placed in each groove section, the rigidity is large, and the supporting effect is good; the groove sections are continuously poured, the wall body quality is good, and the anti-seepage effect is good.
本发明公开了一种用于浅基坑围护结构的地下连桩墙及其施工方法，其中包括以下步骤：S1：沿基坑周圈施工导墙；S2：在导墙内利用成槽机成槽，该施工方法在地铁车站附属结构基坑外侧连续成槽，成槽过程中，可通过成槽机仪表盘实时观察槽段垂直度并及时进行纠偏，成槽垂直度高；成槽结束后，利用超声波进行垂直度检测，为安装钢筋笼提供保障；槽段之间通过锁扣管接头进行咬合，后续槽段安装钢筋笼前，对接头进行刷壁，接头防渗漏效果好；钢筋笼制作成方形或圆形，重量轻，吊装方便，每个槽段内放置多个钢筋笼，刚度大，支护效果好；槽段连续浇筑，墙身质量良好，防渗漏效果好。
