Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1-3, the infiltration-preventing pressure-reducing lining segment splicing structure for tunnel construction provided in this embodiment includes two lining segments 1 and a connecting steel member 2, where the connecting steel member 2 is fixed between the two lining segments 1; the both sides of connecting steel part 2 are provided with water drainage tank 7, the both sides of connecting steel part 2 near the outer wall are provided with infiltration filter plate 6, it is in to connect steel part 2 infiltration filter plate 6 below is provided with water conservancy diversion inclined plane 21, water conservancy diversion inclined plane 21 extends to in the water drainage tank 7. The water seepage filter plate 6 can be made of a material similar to diatomite and has certain strength and strong water seepage capability. The water that permeates out can permeate infiltration filter plate 6 to water conservancy diversion inclined plane 21 department, then in water drainage tank 7 is arrived in the water conservancy diversion inclined plane 21 water conservancy diversion, can in time discharge the water that permeates.
In order to play better prevention of seepage function, still include triangle plastic sealing strip 4, it is located to connect steel part 2 the position is provided with joint breach 22 below the water drainage tank 7, 4 joints of triangle plastic sealing strip in joint breach 22 with between the lining cutting section of jurisdiction 1, the slope of joint breach 22 is in order to extrude triangle plastic sealing strip 4 warp laminate in 1 lateral wall of lining cutting section of jurisdiction. When 1 outside pressure grow of lining cutting section of jurisdiction, can extrude lining cutting section of jurisdiction 1 and produce certain deformation for lining cutting section of jurisdiction 1 can further extrude triangle plastic sealing strip 4, thereby it is more firm to make the sealed effect of triangle plastic sealing strip 4, and setting up through joint breach 22 makes when connecting steel part 2 and taking place the slope, extrusion triangle plastic sealing strip 4 that joint breach 22 can be better, thereby it increases seal strength to make triangle plastic sealing strip 4 warp.
In order to improve the anti-seepage performance, the inboard junction that is close to of lining cutting section of jurisdiction 1 is provided with the installation boss, the installation boss with be provided with water-swelling sealing rod 5 between the connecting steel piece 2. Preferably, adjusting bolts 3 are alternately arranged on two sides of the mounting boss along the length direction, and the other ends of the adjusting bolts 3 penetrate into the connecting steel part 2 and do not completely penetrate through the connecting steel part 2. Adjusting bolt 3 of screwing up one side can make connecting steel member 2 toward this side offset to joint breach 22 can be better extrusion triangle plastic sealing strip 4, thereby makes triangle plastic sealing strip 4 warp and increase sealing strength. The offset direction of the connecting steel piece 2 can be changed by adjusting the adjusting bolts 3 at different sides, so that the adjustment can be convenient. And meet water inflation sealing rod 5's setting up makes when this side infiltration, meets water inflation sealing rod 5 inflation grow and plugs up the clearance, and the inflation can produce certain pressure extrusion connecting steel 2 simultaneously to can link and adjust extrusion triangle plastic sealing strip 4, make sealed effect better.
Preferably, 4 closed angles of triangle plasticity sealing strip extend to one side of water-swelling sealing strip 5, just 5 one end of water-swelling sealing strip extends to 4 one side intermediate positions of triangle plasticity sealing strip. Thereby make rivers when permeating water inflation sealing rod 5 positions, water inflation sealing rod 5 just begins the inflation to extrude triangle plastic sealing strip 4 and make its deformation, thereby reinforcing triangle plastic sealing strip 4's leakproofness.
