The invention relates to the technical field of shield tunneling construction, in particular to a shield tunneling unearthing control method. The shield tunneling unearthing control method comprises the following steps that S1, data of residual slag quantity are recorded, specifically, before tunneling, the data of the residual slag quantity are recorded; S2, slag hopper numbering and weighing identification are carried out; S3, a weighing record chart of each slag hopper is made; S4, shield tunneling construction is carried out, specifically, the slag amount of each ring is calculated when each ring is tunneled; S5, the amount of the residues is converted, specifically, the weight of the residues obtained by weighing the gantry crane with the mark cleaned is subtracted from the weight of each residue hopper of each tunneling ring after the soil residues are poured, and the amount of the residues is converted; and S6, the unearthed soil volume is accounted and reported, specifically, during tunneling, the slag discharge volume of each ring is converted into standard 1.2 m slag discharge volume, the slag volume converted by weighing of the gantry crane is subtracted, and the data are sorted and sent to a project risk management department. According to the shield tunneling unearthing control method, the unearthed soil volume can be accurately and strictly controlled, the risk of settlement or upheaval of the ground is reduced, and a subway line can be normally constructed and normally and smoothly operated in the future.
本申请涉及盾构掘进施工的技术领域,尤其是涉及一种盾构掘进出土控制方法,其包括以下步骤:S1、记录残存渣量的数据:在掘进前,记录残存渣量的数据;S2、渣斗编号和称重标识;S3、制作每辆渣斗的称重记录表;S4、盾构掘进施工:每掘进一环,计算每环渣量;S5、残渣方量的换算:把每一个掘进环的每个渣斗倒完土渣后的重量减去清理干净标识的龙门吊称重所得的残渣重量并换算成残渣方量;S6、出土量的核算上报:掘进期间,每环的出渣量换算成标准1.2m出渣方量,减去龙门吊称重换算的残渣方量,整理发送至项目风险管理部门,本申请能够实现精确严格地控制出土量,降低地面出现沉降或隆起的风险,使地铁线路能够正常施工、未来正常顺利地运行。
