Description
The present invention relates to a kind of not with the marine pontoon bridge and the erection method thereof of sea sloshing.
Common pontoon bridge only suits to use on the water surface in right up and down river or lake, of the present invention a kind ofly also do not find as yet in the prior art with the marine pontoon bridge of sea sloshing.
Common pontoon bridge be with some ducted bodies arranged side by side, ship or raft as buoyancy aid, and then and bridge that cause some dull and stereotyped toward top shop.This bridge construction is simple, is easy to build, and cost is low, and can build apace, and therefore, it has just become military with one of bridge and interim best bridge kind of using bridge.But this bridge also has tangible deficiency, that is exactly, this bridge is the bridge that supports by buoyancy aids such as the ducted body that swims in the water surface, ship or rafts, its bridge floor stable bad, shaken by the wave impact meeting, and the load of bridge floor also can cause significantly when changing and rock, so this bridge is not suitable for using on the wavy water surface, especially is not suitable for wavy big marine the use.
The object of the present invention is to provide a kind of bridge floor good stability, not only when the loads change of bridge floor, bridge floor does not take place significantly to rock, and under the situation that impacted by wind and waves, the suitable pontoon bridge that at sea uses that bridge floor does not take place obviously to rock yet and the erection method of this kind pontoon bridge.
After the objective of the invention is common pontoon bridge carried out following transformation, and set up according to following method that the back realizes.
This pontoon bridge is the same with common pontoon bridge, and it is also swum in the ducted body in the water and be layered on top bridge deck and form by a plurality of, and the top that it is characterized in that ducted body 1 is welded with the bridge pier 3 with shape steel formation, the top bridge deck 2 of spreading of bridge pier 3; The top of ducted body 1 also has the manhole 4 of with closure 5, and lower part series has many ropes 6, and the other end of rope 6 ties up to respectively on the mass 7 that is placed on different directions or the water-bed rock 8.
When setting up, prefabricated ducted body 1 is transported on the water surface that will build pontoon bridge, before ducted body 1 is in place, pour water in ducted body 1 by manhole 4 earlier, the weight of ducted body 1 is increased, buoyancy reduces, produce corresponding sinking, when the seawater identity distance stops to pour water during from 0.5 meter, ducted body 1 top, and take advantage of the seawater time of low water with 6 tensions of ducted body 1 bottom direct bearing rope, make ducted body 1 in place, simultaneously with the other end of rope 6, tie up to firmly separately on the mass 7 that is put in different directions or the water-bed rock 8, afterwards again with the water of extracting 1.5 to 2 times of design bearing capacities that weight is equivalent to this ducted body 1 in the therefrom empty body of water pump 1 out, make the weight saving of this ducted body 1, buoyancy increases, and ducted body 1 at this moment ought to produce corresponding come-up, but because ducted body 1 has been tied up to by rope 6 when sinking on the rock 8 at the mass 7 or the bottom firmly, limit by the pulling force of mass 7 or rock 8 and rope 6, make ducted body 1 not float, and be in as before on original position; This that is to say that ducted body 1 has been reserved deflection when setting up.Again bridge deck 2 are installed at last, just can be unified into a complete pontoon bridge to a plurality of such ducted bodies 1.
Because ducted body 1 of the present invention is when setting up, enough deflections have been reserved, and tied up to respectively on the mass 7 that is placed on different directions or the water-bed rock 8 by many tightropes 6, this just makes ducted body 1 be subjected to pulling force restriction from the rope 6 of all directions, and has been fixed firmly; Because this restraint is greater than the impact side of wave, so ducted body 1 can not moved by wave; Because the deflection that ducted body 1 is reserved is greater than the design bearing capacity of this bridge, thus the just inevitable deflection of reserving less than ducted body 1 of the load that produces during vehicular movement, so bridge floor can not take place obviously to rock yet during vehicular movement.
Method of the present invention not only is used in river and the lake and sets up pontoon bridge, and can be used for having boisterous big nautical mile to set up pontoon bridge, moreover, ducted body among the present invention 1 and erection method thereof also can be used as in the construction of sea port dock, marine factory, marine residential district, open sea aeroplane field and offshore work platform.
Fig. 1 is the elevation of pontoon bridge;
Fig. 2 is the plan view of pontoon bridge;
Fig. 3 is the A-A section.
Describe optimum implementation of the present invention in detail below in conjunction with each accompanying drawing.
The represented ducted body 1 of Fig. 3 is 5 meters of diameters, and high 6 meters cylinder, its shell are that the inwall 11 that the outer wall 10 that is welded into by steel plate and steel concrete are built constitutes jointly.Outer wall 10 is that the carbon steel sheet with 8 millimeters thick is welded, and it can also play the effect that prevents penetration of sea water except the effect of opposing external force is arranged.The inboard of outer wall 10 is an inwall 11, and inwall 11 is to be made of steel concrete, and wherein reinforcement placement is inside and outside two-layer, and the welding of the steel plate of part outer reinforcement and outer wall 10, and inside and outside wall is become one.The thickness of inwall 11 is decided by the stressed of it, thus thickness difference up and down, thick 300 millimeters of bottom, only thick 100 millimeters of top.
Also be welded with the bridge pier 3 that constitutes with the shape steel at the top of ducted body 1, spreading bridge deck 2 above it, it is the extension body of ducted body 1, makes ducted body 1 extend 4 meters; The effect of bridge pier 3 is when high tide, and bridge deck 2 are not flooded by seawater.
Centre at the top of ducted body 1 also has manhole 4, is stamped seal cover 5 above it, and during sealing, seal cover 5 is to be fixed on the flange of manhole 4 by 8 bolts; In order to strengthen seal, between the flange of seal cover 5 and manhole 4, also be placed with rubber gasket 12.
It is calculated that, about 118 cubic metres of the volume of each ducted body 1, about 90 cubic metres of inner space is conducted oneself with dignity about 70 tons.Prefabricated ducted body 1 is transported on the water surface that will build pontoon bridge, made it aim at the position that to fix substantially.It is calculated that as can be known if ducted body at this moment 1 can be erected to swim in the sea, its will have an appointment length of 3.5 meters is submerged in the seawater.Next, pour water in ducted body 1 by manhole 4, make it increase deflection, sink again 2 meters the time up to ducted body 1, stop to pour water, and take advantage of the seawater time of low water, make ducted body in place 6 tensions of ducted body 1 bottom direct bearing rope, simultaneously with the other end of rope 6, tie up to firmly separately on the mass 7 that is put in different directions or the water-bed rock 8.The diameter of known ducted body 1 is 5 meters, and sea water specific gravity is 1.025 tons/cubic metre, so want to make ducted body 1 to sink 2 meters, just should irritate 40.23 tons water in ducted body 1.Afterwards with extracting 1.5 to 2 times the water that weight is equivalent to the design bearing capacity of this ducted body 1 out in the therefrom empty body 1 of water pump, because the design bearing capacity of ducted body 1 is 20 tons, so just should extract 40 tons water out; That is to say, can all extract the water that pours into ducted body 1 out basically.
Mass 7 under the represented ducted body 1 of Fig. 1, Fig. 2, Fig. 3 is that a length is 3 meters square, and as calculated as can be known, the volume of this mass 7 is about 27 cubic metres, heavily about 70 tons.The volume of having known mass 7 is 27 cubic metres, is about 27.68 tons with regard to having known it at buoyancy in the sea; Because of heavily about 70 tons of mass 7, just known that also its counterweight forces is about 42.32 tons.This shows, only just can be to offset this ducted body 1 because of the buoyancy of discharging seawater and producing by the counterweight of this mass 7.
We know, the deflection of the actual reservation of this ducted body 1 is out and away greater than the design bearing capacity of this bridge, so pontoon bridge of erecting by such ducted body, can guarantee the stable of bridge floor fully, not only the vehicle flowrate that allows in design by the time bridge floor can not take place obviously to rock, and bridge floor can not take place obviously to rock yet under boisterous impact.
What Fig. 1, Fig. 2 were represented is the facade and the plan view of pontoon bridge, and we can be in place other ducted body 1 according to this figure, and is tied up on the mass 7 that is put in different directions or the water-bed rock 8 by rope 6; Afterwards, according to this figure all bridge deck 2 are all installed again, make it to become a complete pontoon bridge; When being necessary, we can also install ancillary facilities such as bridge railings and nightscape lighting lamp for it, make it to become one not only easy to use, and pontoon bridge as safe as a house.
