Summary of the invention
The purpose of this utility model is to solve in overpass engineering; in the less situation of headroom at the bottom of high ferro beam; the problem that between load-bearing I-beam section and catenary, how waterproof is anti-electric; a kind of reasonable in design is provided; be simple and easy to system, there is the anti-electric waterproof board at low clearance grade separation feeding beam catenary position of waterproof, anti-electric duplicate protection.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of anti-electric waterproof board of low clearance grade separation feeding beam catenary position, it is characterized in that comprising some the I-beam sections be arranged in parallel, I-beam section base connects insulcrete by insulated bolt, I-beam section top margin plane is provided with waterproof layer, coordinated by mother-son groove between two pieces of adjacent insulcretes, mother-son groove cooperation place is marked with epoxy resin layer.This programme is using the I-beam section be arranged in parallel as basic framework, to ensure integrally-built rigidity, it is firm that other all parts all adopt insulated connecting piece to carry out, according to the area of guar plate, more than one piece veneer is adopted to carry out abandoning group, by the interfitting structure of mother-son groove, this case ensures that the whole plate after combination is smooth seamless, and use epoxy resin to carry out glue seals.Waterproof layer is positioned at above whole guar plate, and same and I-beam section is tightened to one, makes overall construction intensity reach maximum.
As preferably, described waterproof layer has the weathering of gradient≤1:100, establishes sealing rod in surrounding, and establishes drain pipe at lower curtate catchment.Because setting height(from bottom) is low clearance space, the gradient of weathering is as far as possible little, and is collected overboard in drain pipe draining by sealing rod.
As preferably, described waterproof layer comprises the bamboo slab rubber being positioned at lower floor, is provided with PE membrane waterproofing above bamboo slab rubber.Double-protection, safe and reliable.
As preferably, described adjacent bamboo slab rubber seam and the seam of adjacent PE membrane waterproofing stagger, and at connecting sewing place infusion epoxy resin.Epoxy resin is adopted to carry out adhesive seal, the PE membrane waterproofing of staggered bamboo slab rubber, the defect avoiding seam to concentrate causing.
As preferably, in described some the I-beam sections be arranged in parallel, connected by middle steel plate between inside two adjacent I-beam section top margins.The guar plate of this case uses above Engineering Task point, and himself configuration aspects weight demands is light and requirement of strength is large, and middle steel plate links into an integrated entity one group of I-beam section or all I-beam sections.
As preferably, described I-beam section ground connection, grounding resistance is less than 10 Ω.Ensure the anti-electric requirement of basic framework.
As preferably, the frequency breakdown voltage ≮ 52.5kv of described insulcrete.Be all the requirement of 27.5kv according to the contact system of electrified railway and the voltage of catenary, the frequency breakdown voltage of insulcrete is set, and carry out all-insulated plate disruptive test.
The beneficial effects of the utility model are: this device is easily processed, easy for installation, integrated cost is low; energy repeated usage; insulating power press industry standard design; upper strata water-proof drainage, lower floor insulate anti-electric; duplicate protection; under adapting to low clearance grade separation operating environment, between load-bearing I-beam section and catenary, overall anti-electric waterproof, ensure that the personal safety of workmen.
