Detailed Description
As shown in fig. 1, the utility model provides a can resist steel trestle of strong water impact, steel trestle 1 lower part is supported through inserting many steel-pipe piles 2 of beating in the bottom riverbed, installs a diversion device that divides water on the steel-pipe pile 2 of every upstream side of trestle, the detailed structure of diversion device that divides water is shown in fig. 2, fig. 3, fig. 4, include a set of circular cuff 3 of dress on steel-pipe pile 2 and support on the riverbed, a staple bolt 4 of embracing tightly on steel-pipe pile 1 and being located the surface of water above, and two rectangular guide plates 5; one long edge of each of the two guide plates 5 is welded with the outer wall of the hoop 3 and the outer wall of the hoop 4, and the other long edges of the two guide plates 5 are welded with each other and face the upstream face.
The hoop 4 of the water diversion and flow guide device comprises a circular hoop plate, an opening is formed in one side of the hoop plate, two connecting plates 41 extend out of two sides of the opening, and the two connecting plates are connected through bolts 42; the hoop 3 is a round steel cylinder with a certain height; the two guide plates 5 are two rectangular steel plates.
In order to ensure the welding firmness of the guide plate and the hoop, the two guide plates 5 of the water diversion and guide device are preferably welded with the hoop and the hoop along the circular tangent lines of the hoop 4 and the hoop 3 respectively.
In order to further enhance the strength of the water diversion and flow guide device, two triangular supports 6 can be respectively arranged between the hoop and the hoop of the water diversion and flow guide device and the two flow guide plates, each triangular support 6 can be formed by welding 3 sections, each section forms one side of each triangular support, two ends of one side of each triangular support 6 are respectively welded with the side walls of the two flow guide plates 5, and one ends of the other two sides of each triangular support are respectively welded with the outer walls of the hoop 4 and the hoop 3.
Furthermore, a vertical rod 7 can be arranged between the two guide plates 5 along the longitudinal direction of the guide plates, and the welded edges of each triangular support 6 and the two guide plates are respectively welded with the vertical rod.
To erect the steel trestle in mountain river, in order to resist the impact of flood in rainy season, still can set up an inclined strut steel-pipe pile 8 at the steel trestle dorsal side just to the steel-pipe pile of every trestle dorsal side, the lower extreme slant of every inclined strut steel-pipe pile 8 is inserted into and is beaten into the riverbed, and the upper end inclines to the trestle bridge floor direction, is connected every inclined strut steel-pipe pile 8 rather than just trestle steel-pipe pile 2 through two flat link rods 9.
Further, in order to enhance the supporting capability of the diagonal-bracing steel-pipe piles 8, river sand may be filled in each diagonal-bracing steel-pipe pile.
The utility model discloses a divide water guiding device can make into wholly in the processing field, and the length of guide plate is set for according to the construction district water level during preparation, will make the staple bolt highly exceed the waterline more than, and the diameter of staple bolt and cuff will equal or slightly be greater than the external diameter of steel-pipe pile.
