Background technology
Tunnel Mining Method boring construction process often causes the redistribution of surrouding rock stress and the release of initial field stress, and after this will cause tunnel excavation, tunnel radially occurs convergent deformation, and vault occurs sedimentation or protuberance deformation；Vibration wave produced by face explosion also can produce impact in various degree to adjoining rock stability and surface buildings safety；After propping up at the beginning of tunnel spray concrete, these impacts will cause surrouding rock deformation, intuitively show as tunnel surrounding and supporting displacement etc.；These change whether entail dangers to building safety, if can affect order orthobiosis in city, it is necessary to depend on and measure in effective construction monitoring；Reflected and supervise and guide construction by monitoring, thus reach safety, economic purpose.
Existing tunnel vault settlement monitoring point is buried assembly underground and is generally comprised plate body, reflecting piece and be provided with the expansion bolt of hook, the one side of plate body be for the reflecting piece joint face that reflecting piece connects, relative another side be for the hook connecting junction that is connected of hook；Plate body uses metal material to make, and hook is fixed on hook connecting junction by welding manner, and welding process is relatively complicated, improve the labor intensity of staff, and it is easily caused reflecting piece joint face appearance protuberance, and cause reflecting piece to be stably connected with plate body completely, reflecting piece easily comes off；Additionally, due to tunnel seepage in underground is more, a lot of reflecting piece come off after being drenched by subsoil water, cause observing.
Therefore, it is accomplished by a kind of tunnel vault settlement monitoring point and buries assembly underground, hook is without being fixed on hook connecting junction by welding manner, reduce the labor intensity of staff, reflecting piece is made stably to be connected with plate body, prevent from coming off, can also prevent reflecting piece from being drenched by subsoil water simultaneously, it is ensured that being smoothed out of observation work.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of tunnel vault settlement monitoring point to bury assembly underground, hook is without being fixed on hook connecting junction by welding manner, reduce the labor intensity of staff, reflecting piece is made stably to be connected with plate body, prevent from coming off, can also prevent reflecting piece from being drenched by subsoil water simultaneously, it is ensured that being smoothed out of observation work.
Tunnel vault settlement monitoring point of the present utility model buries assembly underground, including plate body, reflecting piece and the expansion bolt being provided with hook, the one side of described plate body be for the reflecting piece joint face that reflecting piece connects, relative another side be for the hook connecting junction that is connected of hook；Described hook connecting junction is provided with the positioning checkpoint for coordinating location with hook, and the edge of described reflecting piece joint face upwardly extends formation for the convex edge surrounding reflecting piece.
Further, at least provided with three positioning checkpoints, described positioning checkpoint is circumferentially distributed.
Further, described positioning checkpoint is uniformly distributed circumferentially.
Further, the highest face of described convex edge is positioned on reflecting piece.
Further, described reflecting piece is connected on plate body with bonding way.
Further, described expansion bolt includes screw rod, it is combined with expansion sleeve on described screw rod, the two ends of described screw rod are respectively arranged with long thread segment and short thread segments, long thread segment and short thread segments mid portion are non-threaded section, it is provided with the nut matched with its screw thread on long thread segment, short thread segments is provided with the concentric reducer nut matched with its screw thread.
Further, described plate body uses elastomeric material to make.
The beneficial effects of the utility model: tunnel vault settlement monitoring point of the present utility model buries assembly underground, hook connecting junction is provided with the positioning checkpoint for coordinating location with hook, make hook without hook connecting junction can be fixed on by welding manner, reduce the labor intensity of staff, make reflecting piece stably be connected with plate body, prevent from coming off；Meanwhile, the convex edge on reflecting piece joint face can also prevent reflecting piece from being drenched by subsoil water, it is ensured that being smoothed out of observation work.
Accompanying drawing explanation
With embodiment, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, Fig. 2 is A-A sectional view in Fig. 1, as shown in the figure: the tunnel vault settlement monitoring point of the present embodiment buries assembly underground, including plate body 1, reflecting piece 2 and the expansion bolt being provided with hook 3, the one side of described plate body 1 be the reflecting piece joint face 11 for connecting with reflecting piece 2, relative another side be for link up with the 3 hook connecting junctions 12 being connected；Described hook connecting junction 12 is provided with the positioning checkpoint 5 for coordinating location with hook 3, and the edge of described reflecting piece joint face 11 upwardly extends formation for the convex edge 13 surrounding reflecting piece 2；Hook connecting junction 12 is provided with the positioning checkpoint 5 for coordinating location with hook 3 so that hook 3, without being fixed on hook connecting junction 12 by welding manner, reduces the labor intensity of staff, makes reflecting piece 2 stablize with plate body 1 and is connected, prevents from coming off；Meanwhile, the convex edge 13 on reflecting piece joint face 11 can also prevent reflecting piece 2 from being drenched by subsoil water, it is ensured that being smoothed out of observation work；The highest face of described convex edge 13 is positioned on reflecting piece 2, effectively to stop subsoil water；The height of convex edge 13 is about 1.0cm；Described reflecting piece 2 is connected on plate body 1 with bonding way, convenient and reliable；Owing to without welding plate body 1, plate body 1 can use the elastomeric material of hard to make.
