Percolating water usually occurs in the highway tunnel construction seam, and the main method of punishment percolating water is to bury drainpipe underground at the construction joint of tunnel place.In this process, need on tunnel lining concrete, open the groove of burying drainpipe underground, slot just must be at the concrete surface slot.The method of slot is on tunnel lining concrete at present: artificial hand-held concrete cutting machine is at lining cutting top layer slot, and its weak point is: slot is of poor quality, and the seam cut is deep mixed, the left and right distortion; Labor strength is large, not only wants the Sustainable Control cut direction, also will apply cutting pressure; Operational danger is large, and concrete applies reaction force to the cutting blade turned at a high speed, causes cutting blade to skid off joint-cutting, and cutting machine runs and alters at body structure surface.
The utility model content
The utility model provides a kind of tunnel lining concrete cutter sweep, can make the groove depth cut into shallow consistent, and section is neat, and conveniently moving has been saved a large amount of manpowers, guaranteed workman's work safety, and its low cost of manufacture, can promote the use of simultaneously.
For solving above technical problem, the utility model provides following technical scheme: a kind of tunnel lining concrete cutter sweep, comprise cutter and supporting steel frame, and cutter connects on supporting steel frame, and described supporting steel frame is fixed on the tunnel overhaul Covered face of Smooth Slide; Described cutter comprises concrete cutting machine, left slideway, right slideway, upper connecting rod, lower angle cleat and brace, and the cutter two ends are left and right slideway, is equipped with chute on left slideway and right slideway; The top of two slideways is connected respectively upper connecting rod and lower angle cleat with bottom, and the outside of left and right slideway is respectively arranged with several braces; Described concrete cutting machine chassis be arranged on chute and with chute for being slidably connected; On described lower angle cleat, be provided with locating hole, lower angle cleat is fixed on the tunnel overhaul Covered face of Smooth Slide by locating hole; Described supporting steel frame is left-right symmetry formula structure, by transverse supporting rod, connect, comprise inclined support bar, middle part horizontal support bar, lower horizontal support bar, vertical supporting rod and transverse supporting rod, the head and the tail two ends of vertical supporting rod connect middle part horizontal support bar and lower horizontal support bar, and inclined support bar is connected in the top of middle part horizontal support bar.
Further, the cross section of described inclined support bar, middle part horizontal support bar, lower horizontal support bar, vertical supporting rod and transverse supporting rod is identical.
Further, described brace is arranged on top, middle and lower part and the bottom of left slideway and right slideway, corresponding support bar, middle part horizontal support bar and lower horizontal support bar are provided with connecting hole, on brace, also are provided with connecting hole, and cutter and supporting steel frame are with bolts by connecting hole.
Further, described left slideway and right slideway and upper connecting rod and lower angle cleat are all with bolts.
This tunnel lining concrete cutter sweep that the utility model relates to, it is simple in structure, and easy accessibility can guarantee the quality of cutting groove, also can increase work efficiency.

The specific embodiment
As shown in Figure 1, the cutter of tunnel lining concrete cutter sweep as depicted in figs. 1 and 2 comprises: concrete cutting machine, left slideway 1, right slideway 2, upper connecting rod 6, lower angle cleat 5 and brace 11.
The supporting steel frame of tunnel lining concrete cutter sweep as shown in Figure 3 and Figure 4, comprise: inclined support bar 17, middle part horizontal support bar 18, lower horizontal support bar 19, transverse supporting rod 20 and vertical supporting rod 21, lower horizontal support bar 19 are fixed on tunnel overhaul road 13; During use, cutter is connected with supporting steel frame connecting hole 16 bolts by cutter connecting hole 15 with supporting steel frame, is assembled into the tunnel lining concrete cutter sweep.Preparation completes.Then on the tunnel-liner surface, mark pre-tangent line and cutting blade 8 is placed on pre-tangent line, next in the position that marks the locating hole 4 on lower angle cleat 5 on the tunnel overhaul Covered face of Smooth Slide, as shown in Figure 6, then in locating hole 4 positions on tunnel overhaul Covered face of Smooth Slide 13, hole vertically downward, then pass through fixedly tunnel lining concrete cutter sweep of locating hole 4 use screw rods, next by concrete cutting machine handle 10, concrete cutting machine is pushed into to the peak for the treatment of tangent line and controls along chute 3, start concrete cutting machine, and on inclined support bar 17, apply the pressure on vertical lining cutting surface.Pitch cutting 8 incision concrete certain depths to be cut, and lower floor's steel disc 24 of left slideway 1 and right slideway 2 is closely connected when lining cutting is surperficial, unclamps solidifying native cutting machine handle, and on inclined support bar 17, apply the pressure on vertical lining cutting surface always.Acting under self gravitation under, concrete cutting machine along slideway 3 down slidings, cuts pre-joint-cutting 9.After pre-joint-cutting cutting, remove the power and the interior screw rod of locating hole 4 that apply on inclined support bar 17, can carry out the operation of next joint-cutting.
Use when basis is novel carries out the joint-cutting operation, only need on inclined support bar 17, apply the pressure on a vertical lining cutting surface, along slideway 3 down slidings, cut pre-joint-cutting 9 concrete cutting machine can act under self gravitation under.
It is convenient that outward appearance and the location of tunnel-liner are not damaged in the location of tunnel lining concrete cutter sweep.
As shown in Figure 5, the upper strata steel disc 22 of left slideway and right slideway, middle level steel disc 23, lower floor's steel disc 24 are bending, and radius of curvature is identical with the tunnel side wall design radial.Can adjust according to the depth of joint-cutting the thickness of lower floor's steel disc.
The specific embodiment described in the utility model does not form the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
