The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
Referring to Fig. 1, the anti-wind and snow corridor of a kind of railway that the utility model is related is made up of basic system and Roof system.
Referring to Fig. 2, basic system is the board-like cutting retaining wall of stake, includes stake 1 and breast boards 2; Stake 1 file is arranged on curb 4 both sides, and the stake top is provided with the connection steel plate, and 1 of stake is provided with breast boards 2.Stake 1 adopts C30 steel concrete to build; The stake sectional dimension requires to adopt two kinds of 1.8 * 2.0m and 1.25 * 1.8m according to soil pressure size and stake Deformation control; Stake 1 spacing is 6.0m, and curb 4 top stakes are long to require to adopt 8.0m according to railway clearance, and the pile body buried depth adopts 5 to 8m according to strata condition and stressing conditions; Long φ 16 connecting reinforcements of the pre-buried 1.1m in pile body top are connected with 50 * 50 * 2.5cm steel plate perforation plug welding at pile body end face connecting reinforcement.Breast boards 2 adopts C30 reinforced concrete prefabricated, and breast boards 2 plate rear screeds are filled out the thick sand folder of 0.3m cobble loaded filter, the soil body water after the eliminating stake 1, and cutting pushes up above breast boards 2, and every block of plate is reserved 2 φ 20 connecting holes, is fastened in the stake 1 with bolt with stake.
The Roof system facade shape is an arch, and the arc radius that winds up is 10m, includes roof panel 6, rod member 7, nut ball 8, bearing 9, rest 10 and connector 11.The new construction that roof panel 6 adopts multi-shaft warp knitting glass fabric, resin and relevant auxiliary material to form; Hot strength>=200 MPa, bending strength>=400 MPa, bending modulus>=20GPa; Extension property≤3%, resistance to elevated temperatures index>=70 ℃; Its major advantage is that intensity is high, in light weight, corrosion-resistant, and bearing load for a long time, and glass fiber compound material coefficient of thermal expansion and common metal are suitable; So still have harmony along with its linear expansion coeffcient of increase of content of glass fiber reduces the ceiling structure thermal expansion that comprises glass fiber compound material and steel gradually; The glass fiber compound material durability is good simultaneously, and intensity descends when beginning to receive load, but longterm strength is stable.Be spliced to form arch corridor end face.Rod member 7 two ends are cylindricality termination or cone-shaped end, and material is a seamless steel pipe, and rod member 7 is connected to the space truss structure that forms arch on the nut ball 8 through connector 11, and connected mode adopts bolt sphere 8 to be connected with the leverage high-strength bolt, and form of structure is positive cubic taper.Nut ball 8 adopts No. 45 steel to forge and makes, and high-strength bolt adopts 40Cr or 35VB or 20MnTiB or 35CrMn,, supporting condition is the multi-point support of winding up, strong point fore-and-aft distance 6.0m, lateral separation 12.0m.The space truss structure height is 2m, surface anticorrosion technology, i.e. rust cleaning back brushing alcohol acid rust-inhibiting primer two roads.Nut ball 8 on the space truss structure end face is through being bolted on the roof panel 6, and the nut ball 8 at space truss structure two ends is fixed on the top of stake 1 through bearing; Connector 11 is a screw.
Construction sequence is following:
1) carries out permanent and temporary drainage before the construction, prevent that surface water from flowing into boundary of works area.
