1、地下延续墙适用于地下工程的主体结构、支护结构以及复合式衬砌的初期支护。
1, the underground continuous wall is suitable for the main structure of underground engineering, the supporting structure and the initial support of composite lining.


2、地下延续墙应采用(屋顶)防水混凝土(北京古建材料),胶凝材料用量不应小于400kg/m3,水胶比不得大于0.55,坍落度不得小于180mm。
2, the underground continuous wall should use waterproof concrete, cementitious material consumption should not be less than 400kg/m3, water cement ratio not greater than 0.55, the slump is not less than 180mm.


3、地下延续墙施工时,混凝土应按每一个单元槽段留置一组抗压强度试件,每五个单元槽段留置一组抗渗试件。

3, the construction of underground continuous wall, the concrete should be placed in each unit of a group of compressive strength test pieces, each five units of a group of anti permeability test section.


4、叠合式侧墙的地下延续墙与内衬结构连接处,应凿毛并清洗干净,需要时应作特别(屋顶)防水处理。
4, stacked side wall of the underground continuous wall and lining structure connection, should be cut and clean, if necessary, should be special waterproof treatment.


5、地下延续墙应根据工程要求和施工条件削减槽段数量;地下延续墙槽段接缝应避开拐角部位。
5, the underground continuous wall should reduce the slot number according to the requirements of the project and construction conditions; underground continuous wall joints should avoid the corner.


6、地下延续墙如有裂缝、孔洞、露筋等缺陷,应采用聚合物水泥砂浆修补;地下延续墙槽段接缝如有渗漏,应采用引排或注浆封堵。
6, such as underground continuous wall cracks, holes, reinforcement and other defects, should be used to repair the polymer cement mortar; underground continuous wall joints should be used if there is leakage, drainage or grouting.


7、地下延续墙分项工程检验批的抽样检验数量(关键词优化),应按第延续墙5个槽段抽查1个槽段,且不得少于3、个槽段。
7, the underground continuous wall sub project inspection batch sampling inspection quantity, should be according to the 5 section of the continuous wall of the 1 slot section, and shall not be less than 3, groove section.
