The specific embodiment
As Fig. 1, Fig. 2, the punishment node structure of Fig. 3 and a kind of construction joint of tunnel percolating water shown in Figure 4, comprise the groove 2 that is arranged on constuction joint 1 place, described groove 2 extends to tunnel drainage passage 12 from the position more than the EXIT POINT of percolating water always, in the described groove 2 semicircle pipe 3 is installed, the lower end of described semicircle pipe 3 is connected with tunnel drainage passage 12 by bend pipe 18, the upper end of described groove 2 is provided with a pipe 10, the part of described pipe 10 is positioned at semicircle pipe 3 inside, the upper end of described pipe 10 is provided with elbow 19, the outer wall of described semicircle pipe 3 scribbles silica gel 5, be coated with mortar 7 on the described silica gel 5, position corresponding with elbow 19 on the described mortar 7 is provided with water injection hole 11, and described water injection hole 11 is connected by elbow 19 with pipe 10.When construction joint of tunnel percolating water is punished, determine that by observing lining construction stitches the EXIT POINT of 1 percolating water earlier, and choose described EXIT POINT with the upper part arbitrarily a bit as digging point, measure the length that tunnel drainage passage 12 is put in described cutting, choose a length less than digging the semicircle pipe 3 of point to tunnel drainage passage 12 length, described semicircle pipe 3 is for to be cut into the PVC pipe along its length; From described cutting point, until tunnel drainage passage 12, the diameter of the spacing of joint-cutting and described semicircle pipe 3 about equally at the downward parallel joint-cutting in constuction joint 1 both sides for the usefulness concrete power saw; The concrete that cuts between joint-cutting with clink forms groove 2, with concrete cutting machine groove 2 is repaired, and makes the bottom of groove 2 slightly be wider than the oral area of groove 2; Described semicircle pipe 3 is embedded groove 2 bottoms form semicircle shape draining duct 4, and described draining duct 4 is connected with described tunnel drainage passage 12 with the bend pipe 18 of a diameter greater than semicircle pipe 3 diameters; With the zone between silica gel 5 sealing semicircle pipes 3 and groove 2 cell walls; A pipe 10 is inserted in upper end at described groove 2, and the part of described pipe 10 extend in the described semicircle pipe 3, and the upper end of described pipe 10 has elbow 19, with the zone between silica gel 5 sealing pipes 10 and groove 2 cell walls; By elbow 19 water filling in pipe 10, flushing pipe 10 and semicircle pipe 3, block the end of drainage channel 12 then with water blockoff plug 13, from elbow 19 water filling and continuing for some time once more in pipe 10, check silica gel 5 sealing effects, 5 places have water to ooze out as silica gel, then chisel out the silica gel 5 that water oozes out the place with clink, smear silica gel 5 again; 5 places do not have water to ooze out as silica gel, then use mortar 7 capping semicircle pipe 3 and pipes 10.
As shown in Figure 5, can finish the later maintenance of construction joint of tunnel percolating water punishment by this set, owing to contain a large amount of dirts in the water that leaks out in the constuction joint 1, As time goes on, water flow into the process of drainage channel 12 from draining duct 4, can pile up some mineral stain dirts at the tube wall of semicircle pipe 3, can stop up draining duct 4 along with the continuous richness of mineral stain dirt is long-pending, as chiseling punishment again again, normal operation to the tunnel has brought great inconvenience, but by reserving water injection hole 11 at elbow 19 places, and with shutoff plug 17 with water injection hole 11 shutoff, safeguard in later stage draining regularly duct 4, concrete is to turn on shutoff plug 17, from seizing wire 14 of water injection hole 11 insertions, the lower end of wire rope 14 has a spheroid 15, and the upper end of wire rope 14 links to each other with rotary machine 16.By the rotation of rotary machine 16, drive wire rope 14 and rotate, and then drive spheroid 15 swings, spheroid 15 impacts foulant and causes it and comes off, and maintenance is finished in water flushing again.
On described mortar 7, be coated with one deck fireproof paint 8.Smearing fireproof paint 8 can be to mortar 7 isolation of preventing fires.
Obliquely in the lining cutting of being close to groove 2 both sides in lining cutting, be provided with a plurality of holes, in described hole, be provided with screw 6.Bore a plurality of holes by oblique in the lining cutting of being close to groove 2 both sides in lining cutting, insert screw 6 and tighten in described hole, can make good being fixed on the tunnel-side of lining cutting around the groove 2, the lining cutting when avoiding constructing around the groove 2 is dropped.
Described constuction joint 1 is positioned at the central authorities of groove 2, and the central authorities of described mortar 7 are provided with deformation joint 9.On mortar 7 capping layers, use sheet metal along the standardized road of the bearing of trend of groove 2 deformation joint 9, described deformation joint 9 overlaps with constuction joint 1, owing to be subjected to Temperature Influence, constuction joint 1 has flexible function, so deformation joint 9 and described deformation joint 9 and constuction joint 1 are set to coincide, to satisfy temperature influence, deformation joint 9 on the mortar 7 can have certain dilatability, can not cause when constuction joint 1 stretches mortar 7 drawing cracks are come off, and PVC semicircle pipe 3 and silica gel 5 all have certain elasticity, can not stretching and drawing crack silica gel 5 and PVC semicircle pipe 3 because of mortar 7 when temperature influence.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
