The purpose of this utility model is to overcome deficiency of the prior art, provides working tunnel seton device in a kind of tunnel.
To achieve these goals, concrete technical scheme of the present utility model is:
A kind of tunnel seton device, comprise the flex holder of a band standard trolley, described flex holder movable set is on graticule bar, can fix with holding out against screw after up-down adjustment, described graticule bar is connected with the first clamping part, described first clamping part and the second clamping part are parallel to each other, and carry out fastening by the long spiro nail be arranged on the second clamping part to gripping object therebetween.
As further improvement of the utility model, described first clamping part, the second clamping part and graticule bar adopt same round steel to bend and make.
As further improvement of the utility model, described long spiro nail at least arranges 2, and different in size.
As further improvement of the utility model, described first clamping part and the second clamping part are respectively 2 pieces of band steels; Described graticule bar is located at the top of the first clamping part.
As further improvement of the utility model, described long spiro nail is installed after running through the first clamping part and the second clamping part.
As further improvement of the utility model, the quantity of described long spiro nail is 2.
As further improvement of the utility model, the head of described long spiro nail is provided with the short handle rotated.
As further improvement of the utility model, the standard trolley of described flex holder is provided with the breach of binding.
As further improvement of the utility model, described graticule bar is provided with red white marker.
Adopt tunnel of the present utility model seton device, after tunnel upper layer hanging wire has been constructed, show according to testing result, flexible pavement upper layer planeness standard deviation sigma reaches 0.76mm, improve 0.1mm relative to the direct spreading evenness of equalizer bar in the past many, achieve good practice of construction effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of specific embodiment of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Specific embodiment 1 (U-shaped):
Mainly for the hanging wire setting tool having slit type drainage ditch side in tunnel.Because avris clearance type ditch, tunnel width is generally at 30cm-50cm, without the need to pitch of constructing, therefore can not affecting road roller and roll, can considering for doing the fixing region of hanging wire.
As shown in Figure 1, the utility model tunnel seton device adopts the round steel of diameter 2cm one to bend and forms, and form the serpentine being similar to traverse, it has 2 parallel clamping parts (first clamping part 1 and the second clamping part 2); In the utility model, the first clamping part 1 and the second clamping part 2 are jointly clipped on the cable furrow bank in gutter, is tightened by two long spiro nails 5 of the second clamping part 2 side; These two long spiro nails 5 can get different length according to the thickness shape of furrow bank, to make screw exposed face substantially identical, seem neat, also save material; The head of screw can not be hex nut shape, but a slightly short steel bar of burn-oning is as turning handle, simple and practical.
At the first clamping part 1 of cable furrow bank opposite side, be bent to form graticule bar 4 being folded to close to road surface place, graticule bar 4 cover is filled with flex holder 3, and flex holder 3 can be enclosed within graticule bar 4, behind height up and down position, is tightened with holding out against screw 31.Conveniently steel wire hanging wire is fixing, can offer the breach 33 of a binding on the standard trolley 32 of flex holder 3; In order to show graticule bar, paint marks red and white can be coated on graticule bar 4.
Specific embodiment 2 (I type):
Mainly for the hanging wire setting tool of tunnel without side, gutter.Sometimes tunnel road surface does not establish gutter, but all can there be cable trench both sides, all road surfaces, therefore can consider to utilize the cable tray in cable trench to fix to arrange hanging wire.
As shown in Figure 2, first clamping part 1 of the utility model tunnel seton device and the second clamping part 2 are respectively the thick band steel of 2 pieces of 0.6cm, after the clamping cables bracket of left and right, the long spiro nail 5 utilizing 2 to run through the first clamping part 1 and the second clamping part 2 carries out screwing tight fixing, and keep the first clamping part 1 and the second clamping part 2 in being parallel to each other and upright state, then raise hanging wire height, stride across cable furrow bank and be arranged at inside cable trench, avoid affecting rolling of road roller.
With specific embodiment 1, graticule bar 4 movable sleeve being welded on the top of the first clamping part 1 is filled with flex holder 3; Flex holder 3 can, on graticule bar 4, behind height up and down position, screw tight fixing by holding out against screw 31; Standard trolley 32 is also provided with the breach 33 of binding; Graticule bar 4 also scribbles paint marks red and white.
Below, to utilizing Specific construction step of the present utility model to be described as follows:
The first step: prepare tunnel hanging wire fixed support, " I " type side paver contact surface level-meter support standing screw is increased 30cm simultaneously.
Second step: " U " type, " I " type support are fixed along both sides, tunnel in scene, by straightway 10m, bend 5m pitch arrangement, and checks whether support is fixing firm.
3rd step: control wire rope along the good absolute altitude of tunnel two layback, lineoutofservice signal pull is not less than 800N.
4th step: according to design elevation adjustment wire rope height, and with thin wire by wire rope fixation.
5th step: repeatedly detect with special aluminium alloys guiding ruler in paving process, ensures that paver is walked according to wire rope height.
Finally, it is also noted that what enumerate above is only a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, all distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, and all should think protection domain of the present utility model.
