By using above-mentioned technical proposal, because being provided with multiple first extensions on water pipe, and disposed over
Water pipe is connected by one through hole with the external world, and the liquid in water pipe outwards after volatilization, is inwardly supplemented by check valve.
Preferably, it is vertically arranged with scale on the fly rod.
By using above-mentioned technical proposal, fly rod is mutually arranged with observation bar, records observation bar on fly rod
It is observed behind scale position and periodically；When observing bar in the scale change on fly rod, under tunnel vault may occur
It is heavy, it is further to arrange monitoring personnel to carry out further careful observation.
Preferably, being provided with elastic protective layer outside the water pipe, the elastic protective layer is dried after being coated by SEBS
Form.
By using above-mentioned technical proposal, most tunnel is for vehicle by order to avoid vehicle is because travelling not
It is careful that water pipe is broken or artificially damaged water pipe, in one layer of SEBS elastic protective layer of water pipe outer wrapping, the elasticity of this material
Well and there is good inoxidizability, alleviate caused active force when vehicle collides with water pipe.
Preferably, the tunnel bodies top is provided with hook, the observation bar is hung on hook.
By using above-mentioned technical proposal, observation bar can by be hung on that hook reaches observation bar and tunnel bodies top
Dismantling connection；If observation bar is damaged and can changed in time.
Preferably, the observation bar top is embedded in tunnel bodies top.
By using above-mentioned technical proposal, observation bar is directly embedded in tunnel bodies top, this connection side during construction
Formula is more firm.
In summary, the utility model has the advantages that：Fly rod is connected with hollow ball, and hollow ball swims in liquid level
On, observation rod set is located on fly rod；Because observation bar is connected to tunnel bodies top, when tunnel vault declines,
Observation bar moves down, and changes with the relative position of fly rod.Observation personnel is changed by observing relative position between observation bar and fly rod
Change learns whether tunnel vault settles.Because being connection inside water pipe, the position of each fly rod is all identical
, observation bar is also connected at the sustained height of tunnel body, Observation personnel need to only write down one of which observation bar with floating
Position relationship between bar.This detection mode is built simply, and observation is direct.
