Description

一种可拆卸及精度高的隧道收敛监测挂钩A detachable and high-precision tunnel convergence monitoring hook

技术领域 technical field

本实用新型涉及隧道施工过程中监测领域,具体涉及一种适用于隧道监测的可拆卸及精度高的隧道收敛监测挂钩。 The utility model relates to the field of monitoring during tunnel construction, in particular to a detachable and high-precision tunnel convergence monitoring hook suitable for tunnel monitoring.

可以避免施工机械对收敛挂钩的碰撞;避免地下水对挂钩的腐蚀;挂钩可重复实用从而提高挂钩的使用寿命降低监测成本。 It can avoid the collision of construction machinery on the convergence hook; avoid the corrosion of groundwater on the hook; the hook can be repeated and used to improve the service life of the hook and reduce the monitoring cost.

背景技术 Background technique

隧道监控量测是新奥法的三大支柱之一,对隧道施工过程中施工工艺的调整,支护结构的选型以及支护结构参数选择都起到重要作用。隧道施工中,为了确保隧道周围围岩的稳定性以及隧道本身的安全,施工中必须要对隧道进行监控量测。 Tunnel monitoring and measurement is one of the three pillars of the new Austrian method, which plays an important role in the adjustment of construction technology, the selection of support structures and the selection of support structure parameters during tunnel construction. During tunnel construction, in order to ensure the stability of the surrounding rock around the tunnel and the safety of the tunnel itself, it is necessary to monitor and measure the tunnel during construction.

随着城市地铁隧道的快速发展,隧道施工中的监测工作越来越引起业主方、施工方的注意。隧道监控量测工作中,隧道收敛监测对于判断围岩稳定性状态及施工方法的合理性与否起着重要的作用。因而隧道收敛属于隧道监控量测中的必测项目。目前隧道收敛主要采用隧道收敛计进行监测,隧道收敛计配合收敛挂钩进行监测。收敛挂钩采用带挂钩膨胀螺栓布设于隧道侧壁,由于隧道围岩挖出之后,需要进行喷射混凝土;这就导致带挂钩膨胀螺栓只得在喷射混凝土施做完成之后布设,否则膨胀螺栓被喷射混凝土覆盖。带挂钩膨胀螺栓在施做喷射混凝土后施做,这就使得隧道开挖后的变形情况监测不到,根据工程经验及相关理论,隧道开挖完成与喷射混凝土施做期间隧道围岩变形量最大,对隧道的稳定性影响也越大。 With the rapid development of urban subway tunnels, the monitoring work in tunnel construction has attracted more and more attention from the owners and construction parties. In tunnel monitoring and measurement work, tunnel convergence monitoring plays an important role in judging the stability of surrounding rock and the rationality of construction methods. Therefore, tunnel convergence is a must-test item in tunnel monitoring and measurement. At present, the tunnel convergence is mainly monitored by the tunnel convergence meter, and the tunnel convergence meter cooperates with the convergence hook to monitor. Convergence hooks are arranged on the side wall of the tunnel with expansion bolts with hooks. After the surrounding rock of the tunnel is excavated, shotcrete needs to be carried out; this results in the expansion bolts with hooks having to be laid after the shotcrete is completed, otherwise the expansion bolts will be covered by shotcrete . Expansion bolts with hooks are applied after sprayed concrete, which prevents the deformation of the tunnel from being monitored. According to engineering experience and related theories, the deformation of the tunnel surrounding rock is the largest between the completion of tunnel excavation and the application of shotcrete , the greater the impact on the stability of the tunnel.

带挂钩膨胀螺栓布设于隧道侧壁,由于隧道中往往有装载机、挖掘机等施工机械施工,膨胀螺栓经常被施工机械碰到;轻则导致挂钩倾斜,重则导致挂钩 直接损坏。根据相关监测规范,监测数据应保证连续性和可靠性,然而挂钩被施工机械破坏就不能保证监测数据的连续性和可靠性。隧道内往往有地下水,带挂钩膨胀螺栓常年处于潮湿环境,导致挂钩表明容易锈蚀,挂钩锈蚀容易导致监测误差。目前在建隧道都比较长,根据监测规范要求隧道内间隔5-10m要布设一个监测断面,这样一条隧道建下来需要布设很多收敛挂钩,目前的收敛挂钩大多是永久性的不可回收的,这就大大增加了监测成本,造成了资源的浪费。 Expansion bolts with hooks are arranged on the side wall of the tunnel. Since there are often construction machinery such as loaders and excavators in the tunnel, the expansion bolts are often touched by construction machinery; the slightest will cause the hook to tilt, and the severest will cause direct damage to the hook. According to the relevant monitoring specifications, the monitoring data should ensure continuity and reliability. However, if the hook is damaged by construction machinery, the continuity and reliability of monitoring data cannot be guaranteed. There is often groundwater in the tunnel, and the expansion bolt with hook is in a humid environment all the year round, which makes the hook display easy to rust, and the rust of the hook will easily lead to monitoring errors. At present, the tunnels under construction are relatively long. According to the monitoring regulations, a monitoring section should be arranged at an interval of 5-10m in the tunnel. After such a tunnel is built, many convergence hooks need to be laid. Most of the current convergence hooks are permanent and cannot be recovered. Greatly increased monitoring costs, resulting in a waste of resources.

以上种种因素表明目前隧道收敛监测工作中收敛挂钩的种种不足,这些因素制约了隧道监测工作的精度,增大监测成本。因此,亟需开发一种监测精度高、使用寿命长、安全可靠且经济节约的隧道收敛挂钩。 The above-mentioned factors indicate that the current tunnel convergence monitoring work has various deficiencies in the convergence hook. These factors restrict the accuracy of the tunnel monitoring work and increase the monitoring cost. Therefore, there is an urgent need to develop a tunnel convergence hook with high monitoring accuracy, long service life, safety, reliability and economy.
