Tunnel monitoring measurement is one of three large pillars of New Austrian Tunneling Method, and to the adjustment of construction technology in constructing tunnel process, type selecting and the supporting and protection structure Selecting parameter of supporting and protection structure all play an important role.In constructing tunnel, in order to ensure the stability of country rock around tunnel and the safety in tunnel itself, in construction, monitoring measurement must be carried out to tunnel.
Along with the fast development of urban subway tunnel, the monitoring in constructing tunnel more and more causes the attention of proprietor, construction party.In tunnel monitoring measurement work, convergence monitoring is for judging whether the reasonability of adjoining rock stability sexual state and construction method plays an important role.Thus tunnel convergence belongs to and must survey project in tunnel monitoring measurement.Current tunnel convergence mainly adopts tunnel convergence meter to monitor, and tunnel convergence meter coordinates convergence hook to monitor.Convergence hook adopts band hook expansion bolt to be laid in tunnel-side, after tunnel surrounding digs out, needs to carry out sprayed mortar; This just causes band hook expansion bolt to have to lay after sprayed mortar has performed, otherwise the injected concrete of expansion bolt covers.Band hook expansion bolt performs after performing sprayed mortar, this just make the deformation after tunnel excavation monitor less than, according to engineering experience and correlation theory, during tunnel excavation completes and performs with sprayed mortar, tunnel wall rock deformation amount is maximum, also larger to the stability influence in tunnel.
Band hook expansion bolt is laid in tunnel-side, and owing to often there being the construction machinery such as loader, excavator to construct in tunnel, expansion bolt is often encountered by construction machinery; Light then cause hook to tilt, heavy then cause linking up with direct damage.According to relevant monitoring specification, monitored data should ensure continuity and reliability, but hook is destroyed continuity and the reliability that just can not ensure monitored data by construction machinery.Often have underground water in tunnel, band hook expansion bolt is in wet environment throughout the year, causes hook to show easy corrosion, and hook corrosion easily causes monitor and feedback.All long at built tunnel at present, a monitoring section to be laid according to interval 5-10m in monitoring code requirement tunnel, such tunnel is built needs laying and is much restrained hook, current convergence hook is permanent expendable mostly, this just considerably increases monitoring cost, causes the waste of resource.
All factors show all deficiencies restraining hook in current convergence monitoring work above, and these factors constrain the precision of tunnel monitoring, increase monitoring cost.Therefore, high, the long service life of a kind of monitoring accuracy of exploitation, the safe and reliable and tunnel convergence of economy hook is needed badly.
