Abstract
An auxiliary device for tunnel monitoring cable burying comprises a primary lining and a secondary lining which are used for supporting excavated surrounding rock. The face, facing towards the secondary lining, of the primary lining is provided with a groove, a fixing steel plate used for fixing a hollow bolt is arranged in the groove of the primary lining, the fixing steel plate is tightly attached to the primary lining, geotechnical cloth and a waterproof plate are sequentially laid between the fixing steel plate and the secondary lining, a gasket which is used for fixing and sealing the waterproof plate and a tightening nut are arranged on the outer circumference of the hollow bolt in a sleeved mode, a detection cable which is used for detecting surrounding rock pressure is arranged in the hollow bolt and fixed through glass cement arranged in the hollow bolt in a filling mode, and the two ends of the detection cable penetrate out of the outer end face of the primary lining and the outer end face of the secondary lining respectively. The auxiliary device is convenient to operate and easy to assemble. Compared with a traditional supporting structure, the auxiliary device enables the detection cable in tunnel surrounding rock to be led out of the primary lining structure, and a whole waterproof layer of a tunnel cannot be damaged.
Description
Technical field
The present invention relates to a kind of servicing unit, relate to specifically a kind of servicing unit of burying underground for tunnel monitoring cable.
Background technology
In underground engineering construction, in order to guarantee the safety of constructing tunnel, conventionally need to monitor the force and deformation of country rock, also to carry out first and secondary lining supporting to excavation country rock simultaneously.At present, the supporting and protection structure often adopting is that bolt-spary supports adds secondary lining, and centre arranges splash guard.Therefore, between monitoring measurement and supporting and protection structure, just there is a very sharp-pointed technical problem, being how test cable passes through supporting and protection structure and do not destroy the layer that discharges water of tunnel entirety, is very necessary so design the servicing unit that a kind of tunnel monitoring cable buries underground.
Summary of the invention
Technical problem to be solved by this invention is to overcome the shortcoming that in prior art, test cable passes through supporting and protection structure destructible waterproofing course, a kind of tunnel servicing unit that monitoring cable is buried underground is provided, and this servicing unit has feature simple in structure, easy to use and with low cost simultaneously.
The technical solution adopted in the present invention is: a kind of servicing unit of burying underground for tunnel monitoring cable, comprise first lining cutting and secondary lining that excavation country rock is carried out to supporting, and first lining cutting offers groove on the face of secondary lining, in the groove of described first lining cutting, be provided with the fixation steel plate for fixing hollow bolt, this fixation steel plate is close to first lining cutting, between fixation steel plate and secondary lining, be equipped with successively geotextiles and splash guard, and on the excircle of hollow bolt, be arranged with for the pad of fixing and water-tight plate and screw nut, the inside of hollow bolt is provided with the detection streamer for detection of Tunnel Surrounding Rock Pressure, detection streamer is fixed by the glass cement being filled in hollow bolt, and the two ends of detection streamer pass respectively the outer face of first lining cutting and secondary lining.
Between described pad and splash guard, adopt and carry glue sealing crimping secretly.
Described splash guard adopts glue to be connected with hollow bolt.
Beneficial effect of the present invention: the present invention is simple in structure, easy to operate and easily assembling, this servicing unit, compared with traditional supporting and protection structure, can be drawn liner structure by the detection streamer of tunnel surrounding inside, and not destroy the waterproofing course of tunnel entirety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Mark in figure: 1, first lining cutting, 2, secondary lining, 3, splash guard, 4, fixation steel plate, 5, geotextiles, 6, hollow bolt, 7, pad, 8, screw nut, 9, detection streamer, 10, glass cement.
The specific embodiment
As shown in the figure, a kind of servicing unit of burying underground for tunnel monitoring cable, comprise first lining cutting 1 and secondary lining 2 that excavation country rock is carried out to supporting, and first lining cutting 1 offers groove on the face of secondary lining 2, in the groove of described first lining cutting 1, be provided with the fixation steel plate 4 for fixing hollow bolt 6, this fixation steel plate 4 is close to first lining cutting 1, between fixation steel plate 4 and secondary lining 2, be equipped with successively geotextiles 5 and splash guard 3, and on the excircle of hollow bolt 6, be arranged with for the pad 7 of fixing and water-tight plate 3 and screw nut 8, the inside of hollow bolt 6 is provided with the detection streamer 9 for detection of Tunnel Surrounding Rock Pressure, detection streamer 9 is fixed by the glass cement 10 being filled in hollow bolt 6, and the two ends of detection streamer 9 pass respectively the outer face of first lining cutting 1 and secondary lining 2, between described pad 7 and splash guard 3, adopt and carry glue sealing crimping secretly, described splash guard 3 adopts glue to be connected with hollow bolt 6.
The present invention when mounted, first hollow bolt 6 is penetrated to fixation steel plate 4 welding, arranging detection streamer 9 passes from hollow bolt 6 endoporus, spray first lining cutting 1 at the external surface of fixation steel plate 4, and the inner surface that guarantees fixation steel plate 4 is concordant with first lining cutting 1, and then the inner surface of fixation steel plate 4 is laid geotextiles 4 and splash guard 3 successively, and be connected with bonding glue with hollow bolt 6 junctions at splash guard 3, then successively by pad 7 and rotating nut 8 are installed on hollow bolt 6, perform secondary lining 2 at the external surface of splash guard 3, left backly in hollow bolt 6, set glass cement 10, fill internal void, complete detection streamer and bury the installation of servicing unit underground.
The present invention is simple in structure, easy to operate and easily assembling, and this servicing unit, compared with traditional supporting and protection structure, can be drawn liner structure by the detection streamer of tunnel surrounding inside, and not destroy the waterproofing course of tunnel entirety.
