Underground space bottom plate deformation joint leakage treatment method
The invention relates to the field of building maintenance and repairing, in particular to an underground space bottom plate deformation joint leakage treatment method, which comprises the following steps of: pouring a first joint filling material behind a concrete cushion layer through a grouting hole formed in one side of a deformation joint, retreating a grouting nozzle to a thickness range of a structure bottom plate, and pouring a second joint filling material; a third joint sealing material is injected to the lower portion of the middle-buried water-stop belt through the injection needle tube, the deformation joint above the middle-buried water-stop belt is painted and filled with non-curing rubber waterproof paint, and a drainage pipe extending in the longitudinal direction of the deformation joint is buried in the non-curing rubber waterproof paint through gravel; an external water stop belt and a protection steel plate are arranged at the top of the deformation joint for structural replacement, the treatment mode of external cutting, middle blocking and internal prevention and internal drainage is formed, repeated water seepage is avoided to the maximum extent, long-term effectiveness of deformation joint leakage treatment can be guaranteed, meanwhile, self-repairing can be conducted by refilling waterproof liquid into a drainage pipe under the later complex extreme condition, and the service life of the drainage pipe is prolonged. And the later maintenance cost and maintenance difficulty of deformation joint leakage treatment are reduced.
本发明涉及建筑维护与修缮领域，特别涉及一种地下空间底板变形缝渗漏治理方法，通过变形缝一侧成型的注浆孔，向混凝土垫层后方灌注第一填缝料，再后退注浆嘴至结构底板厚度范围内灌注第二填缝料，再通过注射针管向中埋止水带下方注射第三填缝料，并对中埋止水带上方变形缝涂刷封填非固化橡胶防水涂料，在非固化橡胶防水涂料内通过砂砾埋设沿变形缝纵向延伸的排水管，在变形缝顶部设置外置止水带和防护钢板进行结构置换，形成外截、中堵和内防内排的治理方式，最大程度的避免出现渗水反复，可确保变形缝渗漏治理的长期有效性，同时，在后期复杂极端条件下可通过向排水管回灌防水液进行自我修补，减少变形缝渗漏治理的后期维护成本和维护难度。
