JCT型灌缝胶在圆管涵加固中的应用

Application of JCT sealing glue to strengthening the pipe culverts

JCT型灌缝胶强度高、收缩小,有着良好的力学性能。用于维修补强混凝土结构,施工简单方便,在桥板(梁)和涵洞加固补强中日益得到了广泛的应用。文章主要介绍了圆管涵裂缝的原因及采用高渗透性、高粘结强度的灌缝胶修复混凝土裂缝和加固补强圆管涵的施工技术。

The JCT sealing glue is high in strength, small in shrinkage, low in viscosity with good mechanical properties, and easy to construct. It can be used for reinforcing the concrete structures, especially in extensive application to strengthening the deck slabs （ or beam ） and culverts. This article analyzes the factors causing cracks of pipe culverts, with presentation of construction technology for repairing cracks and strengthening the pipe culverts with sealing glue in high permeability and high strength.
