Pressure sewage pipe diversion method
The invention relates to a pressure sewage pipe diversion method, and belongs to the technical field of municipal engineering. The method comprises the following steps of S1, positioning an inspectionwell; S2, enclosing and protecting; S3, arranging cast-in-situ bored piles at the bottom of the inspection well; S4, carrying out double-liquid layered grouting reinforcement on the bottom of the inspection well; S5, excavating an inspection well foundation pit, and binding main reinforcements at the tops of the cast-in-situ bored piles and inspection well bottom plate reinforcements together; S6, carrying out binding, formwork erecting and pouring on the whole inspection well; S7, laying a new pressure sewage pipe; and S8, cutting off the original pressure sewage pipe, blocking the originalpressure sewage pipe, carrying out water pumping and air exhaust treatment on the inspection well, after completing treatment, detaching the blocking, installing a connector pipe and an elbow pipe, and finally sealing a cover. The method has the effects of high construction stability and low danger coefficient.
本发明涉及一种压力污水管改道方法，属于市政工程技术领域，包括如下步骤：S1：窨井定位；S2：围护；S3：窨井底部设置钻孔灌注桩；S4：对窨井底部进行双液分层注浆加固；S5：开挖窨井基坑，并将钻孔灌注桩顶部的主筋与窨井底板钢筋绑扎在一起；S6：对窨井整体进行绑扎、支模和浇筑；S7：铺设新压力污水管；S8：切除原压力污水管，对原压力污水管进行封堵并对窨井进行抽水抽气处理，处理结束后拆卸封堵并安装接头管和弯头管，最后进行封盖。本发明具有施工稳定性高，危险系数低的效果。
