文章以宁波轨道交通2号线汽车市场站-甬江北站明挖区间地下连续墙施工为背景,对地下连续墙在微承压水粉砂层采用3种不同方案进行成槽施工方案比选,最终选用在微承压水粉砂层进行降水成槽施工方案,并对地下连续墙在微承压水粉砂层中的降水成槽施工方法做了简要介绍。
文章以寧波軌道交通2號線汽車市場站-甬江北站明挖區間地下連續牆施工為揹景,對地下連續牆在微承壓水粉砂層採用3種不同方案進行成槽施工方案比選,最終選用在微承壓水粉砂層進行降水成槽施工方案,併對地下連續牆在微承壓水粉砂層中的降水成槽施工方法做瞭簡要介紹。

Taking the underground diaphragm wall construction for cut and cover section between Automobile Business station -Yongjiang North station on Ningbo metro line 2 as an example, the paper makes comparison of three different grooving construction schemes for underground diaphragm wall of the micro-pressure bearing water sand layer, having made final decision for selection of construction solution of precipitation grooving in micro-pressure bearing water sand layers. The paper makes a brief introduction of the precipitation grooving construction methods in underground diaphragm wall of micro-pressure of sand and water layer.
