Description of drawings
The view in transverse section of the deformation measuring device that Fig. 1 provides for the utility model;
Fig. 2 is the sectional view at A-A place among Fig. 1;
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated, but therefore the utility model does not receive any restriction.
Fig. 1 shows deformation measuring device that the utility model the provides scheme of installation at the concrete well wall surface; Said deformation measuring device comprises strain reinforcing bar string 1, lead 2 and permanent magnet 4; Wherein, said strain reinforcing bar string 1 is tight shape, is fixed on the inside surface of concrete walling through the two ends of strain reinforcing bar string 1; The inside surface of the said borehole wall is the arc of indent, and said strain reinforcing bar string can be fixed or other fixed form for bolt, support in the fixed form of borehole wall inside surface.Preferably, in the present embodiment, said strain reinforcing bar string is fixed on the concrete well wall surface through bolt 5.Said strain reinforcing bar string can be parallel, vertical with the axis direction of the borehole wall or become 45 degree fixing with axis direction at the fixed-direction of borehole wall inside surface.
Said lead 2 is connected an end of strain reinforcing bar string 1, is used for the current signal of strain reinforcing bar string 1 input or the current signal of output strain reinforcing bar string 1 generation.Said permanent magnet 4 is divided into two, is arranged on the two ends of strain reinforcing bar string 1, for magnetic field environment is provided around the strain reinforcing bar string 1.Preferably, said permanent magnet 4 is fixed on the bolt 5 at strain reinforcing bar string 1 two ends symmetrically.
In order when measuring, to reduce extraneous influence to strain reinforcing bar string 1, preferred, also be provided with protective cover 3 in the outside of strain reinforcing bar string 1; As shown in Figure 2; Said protective cover 3 is a groove shape, and its recessed side is to borehole wall surface and be fixed on the borehole wall, and strain reinforcing bar string 1 is covered in the protective cover 3.Its fixed form can have multiple; Such as fixing through bolted mode; Or on protective cover 3, fixing feet is set, when borehole wall surface is constructed, fixing feet is inserted in the concrete fixing, and other fixed form; Those skilled in the art are easy to expect according to top description, no longer enumerate here.Wherein both can leave the space between protective cover 3 and the concrete walling; Also can not leave the space; When leaving the space between protective cover 3 and the concrete walling; Draw in the space that said lead 2 can pass between protective cover 3 and the concrete walling, perhaps is provided with perforate on the concrete walling in protective cover 3, and said lead 2 is drawn through perforate.
When the deformation measuring device that uses the utility model to provide is measured the concrete well wall surface deformation; As shown in Figure 2, can evenly arrange a plurality of deformation measuring devices in borehole wall inboard, preferably; Can evenly arrange 4-6 deformation measuring device in said borehole wall inboard; Can be arranged on the same level height such as said deformation measuring device, other fixed form can also be arranged certainly, such as being arranged on two different horizontal height.When the concrete well wall surface deforms; The level of tightness of strain reinforcing bar string 1 also changes thereupon, during measurement, gives 1 input of strain reinforcing bar string an electric signal through lead 2; Because strain reinforcing bar string 1 is in the magnetic field environment; Thereby strain reinforcing bar string 1 can be shaken, can feedback electric signal of generation on the strain reinforcing bar string 1 that in magnetic field, shakes, the frequency of said feedback electric signal corresponding to the level of tightness of strain reinforcing bar string 1; The feedback electric signal that returns through lead 2 reaches the ground monitoring chamber through gathering optical fiber, and the researchist can analyze the distortion situation of the borehole wall through research feedback electric signal.This measurement mechanism is simple in structure, and is easy to use, can measure the deflection of concrete well wall surface accurately.
