Deep foundation pit waterproof construction and subway expansion joint leakage maintenance method
The invention belongs to the technical field of civil engineering, and particularly relates to a deep foundation pit waterproof construction and subway expansion joint leakage maintenance method. The deep foundation pit waterproof construction and subway expansion joint leakage maintenance method comprises the following steps that 1, a base layer is cleaned, wherein an original expansion joint waterproof adhesive tape is removed, then a notch is cleaned, the notch must be clean, floating dust, sundries, open water and the like cannot exist, and attention is paid to keep the base layer clean and sanitary and keep the base layer in a dry state at any time; 2, slotting or drilling is carried out, wherein an air pick is used for chiseling away an original beam end expansion joint concrete structure, a cutting machine is used for cutting a joint with the depth being 6-8cm at the positions 3cm away from the left and right of a water seepage gap, and preparation is made for slotting; and 3, slotting is carried out, wherein a groove with the depth being 8cm or a lining crack being 6cm is manually chiseled, and generally, an inverted trapezoidal groove with the inner portion being 6cm large and the outer portion being 4cm small is chiseled. According to the method, a good waterproof effect is achieved, the construction process and the special joint method are improved, and the comprehensive effect of the waterproof material is optimized.
本发明公开的属于土木工程技术领域，具体为一种深基坑防水施工、地铁伸缩缝渗漏维修方法，该深基坑防水施工、地铁伸缩缝渗漏维修方法步骤如下：步骤一：清理基层：拆除原有的伸缩缝防水胶带，然后清理槽口，槽口必须干净，不得有浮尘、杂物、明水等，并随时注意保持基层清洁卫生且保持干燥状态；步骤二：割缝或钻孔：用风镐打凿掉原有的梁端伸缩缝混凝土结构，在渗水缝隙左右各3cm处用切割机割深为6‑8cm的缝，为凿槽做准备；步骤三：凿槽：人工凿出深度为8cm的施工缝或6cm的衬砌裂缝的槽，一般凿成内大6cm外小4cm施工缝的倒梯形槽，该发明实现较好的防水效果，提高施工的工艺和特殊节点做法，优化防水材料的综合效果。
