摘要
结合工程实例,介绍了豆砾石回填材料、回填设备及其回填步骤,为了取得豆砾石回填灌浆的有关参数,在长2 300 m洞段作为灌浆试验段进行了灌浆试验,并分别对两次试验方案进行了分析,最终取得了合适的灌浆参数,可供类似工程参考。
Combined with practical work the backfilling materials of pea gravel, construction equipment and construction steps are introduced as well as some parameters for grouting. At the same time grouting test is carried to in one part of tunnel with 2 300 m long. According to two test schemes respective analysis is made. In the end proper grouting parameters are obtained, which provide references for similar works.
