Engineering pipeline excavation construction method
The invention belongs to the field of engineering construction, and particularly relates to an engineering pipeline excavation construction method. According to the method, mechanical damage to the pipeline when the pipeline is excavated through an excavator is avoided, the idea that the overburden layer on the upper portion of the pipeline layer is flushed through water flow is adopted, and the to-be-excavated pipeline can be protected to the maximum extent; meanwhile, by means of the hollow expansion characteristic of water storage bags of the main plugging assembly and the secondary plugging assembly, on one hand, sewage generated in the flushing process is absorbed, and on the other hand, the water storage bags of the main plugging assembly and the secondary plugging assembly achieve the purpose of plugging the rear end of the tunnel through the gravity pressing effect of the sewage and the volume expansion of the water storage bags; the muddy water generated in the flushing process is prevented from overflowing everywhere, and meanwhile collection of the muddy water is facilitated; the outer box component, the inner box component and the plugging component cooperate with one another to jointly complete the processes of overburden layer extinction and muddy water centralized treatment, and finally the purpose of harmless excavation of the pipeline is achieved.
本发明属于工程施工领域，具体涉及一种工程管线开挖施工方法。本发明避免了通过挖机开挖管线时对管线造成机械损坏，采用水流冲洗管线层上部的覆土层的思路，能最大限度的对待开挖的管线起到保护作用，同时利用主封堵组件和次封堵组件的蓄水囊的中空膨胀特性一方面吸纳因冲洗过程产生的污水，另一方面主封堵组件和次封堵组件的蓄水囊利用污水的重力下压作用和自身的体积膨胀达到封堵坑道后端的目的，避免冲洗过程产生的泥浆水四处外溢同时便于泥浆水的收集；本发明外箱部件、内箱部件、封堵部件协同配合共同完成了覆土层消亡和泥浆水集中处理的过程，最终达到对管线无害开挖的目的。
