The present invention relates to a waterproof sealing device for a deformation joint of a concrete panel of a rockfill dam, which reserves a basic structure of a rubber plate for sealing a joint in the prior art, angle steel for pressing and fixing the rubber plate, and a bolt for fastening the angle steel on a panel. The waterproof sealing device has the following improvement that the rubber plate is converted into multilayer high-strength ageing-resistant rubber. Each component has the installation relationship that a groove for containing the rubber plate and the vertical edge of the angle steel is arranged on the panel, the angle steel is converted from the form that a convex panel of the vertical edge is arranged upwards into the form that the angle steel is buckled, and the vertical edge is embedded into the panel. The angle steel and the panel are pasted by structural glue, the angle steel and the rubber plate are pasted by the structural glue, and the rubber plate and the panel are pasted by the structural glue. A fastening bolt is converted into a female anchor bolt fixedly pasted on the panel and a male anchor bolt matched with the female anchor bolt from an expansion bolt. When used, the sealing device of the present invention has the advantages of good sealing performance, shock resistance, adaptation of large temperature differences and long service life.
Description
Technical field:
The invention belongs to the reservoir construction engineering technical field.
Background technology:
Adopt the big-and-middle-sized reservoir of loose rock dam, upstream slope of dam is used concrete slab more.For adapting to difference variation, all leave deformation joint on the dam facing.For fear of in the dam, seeping water, all be provided with elastic sealing device again at deformation joint from deformation joint.Existing deformation joint sealing device is with common rubber tile joint seal, compresses rubber tile with angle steel, and angle steel then is to be fixed on the concrete slab with expansion bolt.Its concrete structure as shown in Figure 1, wherein 1 is Face Slab of Concrete of Rock-fill Dam; 2 is the deformation joint between the panel; 3 for being filled in the fluid sealant in the deformation joint; 4 is the rubber tile of joint seal; 5 for being pressed on rubber tile in the angle steel on the panel; 6 for being fastened on angle steel the expansion bolt on the panel; 7 are the watertight rubber rod of plug in the deformation joint lower end; 8 is the sealing sheet.The sealing device construction of this structure is fairly simple.Only need on dam facing, get out hole for the expansion bolt in the relevant position, spread rubber tile, use the angle steel flanging, use the fastening angle steel of expansion bolt again, promptly finish installation process at deformation joint.This deformation joint sealing device still can use a period of time in warmer, no iced areas, but in area high and cold, that the four seasons temperature difference is big, then exposes fatal weakness.After using for 1 to 2 year, expansion bolt comes off or is loosening, and rubber tile is torn, the deformation joint water inlet.In China the Northeast, the some places winter temperature can reach again more than 30 ℃ below-40 ℃ summer, and the temperature difference is at 70 ℃-80 ℃.Displacement is big mutually between panel.In addition, in range of stage, ice sheet to the destructive power of sealing device more very.Be subjected to frost-heave force when freeze-up.Ice cube downslide tractive when thawing, north wind in spring is big in addition, and stormy waves is springing up ice raft dam facing is being clashed into repeatedly, because the hard limit of angle steel protrudes in dam facing, is subjected to greater impact power, and directly acts on expansion bolt.The area of adding the hole formation active force on expansion bolt and the dam facing is narrow, and the part gap beyond the compressive plane is bigger again, rocks afterwards very easily earlier to get loose.And the expansion bolt exposed portions serve is higher, and the nut corner angle of upper end are obvious, and the i.e. bigger active force of generation is impacted.Under above-mentioned adverse circumstances, expansion bolt is not loosening, and it is impossible not coming off.Fastening bolt one is loosening.Angle steel must lift, and deformation joint must be intake.Change as untimely repairing, dam facing will be impaired.In addition, winter temperature is low excessively, and difference variation is big in addition, and the rubber tile fracture also is common.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly be hit less, in conjunction with the sealing device of firm Face Slab of Concrete of Rock-fill Dam deformation joint and a kind of ageing-resistant, deformation joint sealed rubber plate that intensity is high.To overcome the above-mentioned deficiency of prior art.
To be that preparation is a kind of be better than commercially available and be used for structure glue of the present invention and be coated in protection glue on the sealing device a further object of the present invention.
Technical scheme of the present invention is to keep joint seal rubber tile in the prior art, presses solidly the angle steel of rubber tile, with bolt angle steel is fastened on basic structure on the panel, the improvement of being done be on the structure of rubber tile is served as reasons down the top layer be the ethylene-propylene-diene monomer glue-line; It is the high-strength carbon fibre layer down; The high-intensity fiber layer is one deck neoprene down; One deck high-intensity fiber again under the neoprene; Orlop is the neoprene layer.The installation of each member relation is: open the groove that holds rubber tile and angle steel vertical edge on panel, angle steel is put the outstanding panel of vertical edge and changed angle steel into and buckle and put by facing upward on panel, vertical edge is imbedded the form of panel.And between angle steel and panel, between angle steel and the rubber tile, utilization structure is gluing between rubber tile and the panel connects.Change fastening bolt into the female crab-bolt that cements on the panel and the public crab-bolt that cooperates with it by expansion bolt.
Below promptly finish basic technical scheme of the present invention.
In order to make bonding firmly durable between the each several part, the present invention prepares the structure glue of two kinds of different purposes:
The prescription of No. 1 structure glue is for by weight, 100 parts of epoxy resin, triethylene tetramine 10-13 part, polysulfide rubber 20-50 part, 650# low molecule pa resin 10-50 part, manganese dioxide 0.8-1.5 part, DMP-30 (0.5-1.0 part), aerosil 0.5-2.0 part, 35 to 75 order quartz sand 50-100 parts, 100 to 120 order quartz powder 50-100 parts.
The prescription of No. 2 structure glue is the chopped carbon fiber 1.0-2.5 part that adds on the basis of structure glue 1 after ultrasonic wave is handled.
Be screwed into locking effect after female crab-bolt in order to strengthen public crab-bolt, leave toply in female crab-bolt endoporus bottom surface, public crab-bolt lower end has vertically cracks, and makes public crab-bolt lower end distending after tightening, and is locked in female crab-bolt.
To use good effect of the present invention be rubber tile and press solidly the part angle steel does not have outstanding position on panel, and public crab-bolt also only has the cap raised face board plane of very thin globular model, significantly reduction be impacted may with the minimizing impact force.Public crab-bolt and panel be not in conjunction with tightly, firmly seep water.Adopt high-strength ageing-resistant rubber plate in addition, prolonged the application life under adverse circumstances.The useful life of a whole set of sealing device prolongs greatly.The protection dam is not impaired because of the deformation joint infiltration.
