Abstract
The utility model provides an auxiliary device used for embedding a tunnel monitoring cable, which comprises a primary lining and a secondary liningused for supporting a to be excavated surrounding rock, wherein a groove is formed in the surface, facing the secondary lining, of the primary lining; a fixing steel plate used for fixing a hollow bolt is arranged in the groove of the primary lining; the fixing steel plate is clung to the primary lining; a geotechnical cloth and a waterproof board are sequentially paved between the fixing steel plate and the secondary lining; the outer circumference of the hollow bolt is sleeved with a gasket and a winding nut used for fixing and sealing the waterproof board; a detection cable used for detecting tunnel surrounding rock pressure is arranged at the inner part of the hollow bolt; the detection cable is fixed by glass cement filled in the hollow bolt; the two ends of the detection cable penetrate through the outer end surfaces of the primary lining and the secondary lining respectively.According to the auxiliary device used for embedding the tunnel monitoring cable, the structure is simple, theoperation is convenient and the auxiliary deviceis easy to assemble; compared with the traditional supporting structures, the auxiliary device is capable of drawing the detection cable at the inner part of the tunnel surrounding rock out of the ling structure and the waterproof layer of the whole tunnel is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of servicing unit, relates 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, to excavation country rock, also to carry out first and secondary lining supporting 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 integral body, is very necessary so design the servicing unit that a kind of tunnel monitoring cable buries underground.
Utility model content
Technical problem to be solved in the utility model 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 scheme that the utility model adopts 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 for the fixing fixation steel plate of 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.
The beneficial effects of the utility model: the utility model is simple in structure, easy to operate and easily assembling, this servicing unit is compared with traditional supporting and protection structure, the detection streamer of tunnel surrounding inside can be drawn to liner structure, and does not destroy the waterproofing course of tunnel integral body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
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 for the fixing fixation steel plate 4 of 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 fixing 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 utility model when mounted, first hollow bolt 6 is penetrated to fixation steel plate 4 welding, arranging detection streamer 9 passes from hollow bolt 6 endoporus, external surface at fixation steel plate 4 sprays first lining cutting 1, 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 with bonding glue, be connected with hollow bolt 6 junctions at splash guard 3, then successively by pad 7 and rotating nut 8 are installed on hollow bolt 6, external surface at splash guard 3 performs secondary lining 2, 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 utility model is simple in structure, easy to operate and easily assembling, and this servicing unit is compared with traditional supporting and protection structure, the detection streamer of tunnel surrounding inside can be drawn to liner structure, and does not destroy the waterproofing course of tunnel integral body.
