The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
As shown in Figure 1, a kind of pontoon bridge that can adapt to the river course SEA LEVEL VARIATION and satisfy river course navigation demand is made up of shore facilities such as the slope ladder access of pontoon bridge main body and two sides or ramps.The two ends of pontoon bridge main body connect the two sides, river course by the springboard lifting appliance, and the pontoon bridge main body is made up of left bridge section, right bridge section (left bridge section and right bridge section constitute main bridge section 1) and intermediate active section 2 among the figure.Described left bridge section, right bridge section and active segment 2 interconnect by a plurality of monomer boats 6 and form.Particularly, as shown in Figure 2, described monomer boat 6 is made up of bridgepile boat 7 and the bridge deck of being located on the bridgepile boat 78, connects by the vertical screw rod that connects successively between the bridge deck 8 of all monomer boats 6.
Just can make its structure that becomes a detachable dismounting by the pontoon bridge main body being carried out above design, to adapt to the fluctuation of river water level.Below to how to do to discuss in detail according to the detailed process of river water level fluctuation adjustment pontoon bridge principal length:
When river water level changes by the main bridge section 1(of increase and decrease left side bridge section or right bridge section) each monomer boat 6 quantity realize adjustment to the pontoon bridge principal length, to adapt to the river course SEA LEVEL VARIATION.Detailed process is as follows: when river water level descends, need to reduce the quantity of monomer boat.Can untie connection screw rods all on the bridge deck 8 of the monomer boat 6 that need dismantle this moment, make this monomer boat 6 be in free movement state, the monomer boat 6 that will be in free state then moves to the appointed place, thereby break away from the pontoon bridge main body, and then the two monomer boats 6 that will disconnect because of dismounting get final product by the vertical screw rod bolt that connects, the pontoon bridge principal length just reduces like this, has adapted to the needs of river width constriction after river water level descends.When river water level raises, can adopt similar method (process is opposite) that the monomer boat 6 that shifts out is joined in the pontoon bridge main body, detailed process no longer is described in detail.
The weight of considering each monomer boat is bigger, and only controlling its disengagement or connect by manpower relatively wastes time and energy, so the present invention has additional the power set that increase and decrease monomer boat is used; These power set are arranged on the monomer boat adjacent with the monomer boat of needs dismounting.During dismounting, with two monomer boats (namely itself needing the monomer boat of dismounting and the monomer boat of drive) as under the integral demounting, sail out of the appointed area by the power set driving, and then two monomer boats are taken apart, dynamic monomer boat is sailed go back to the bridge section place after taking apart, the monomer boat two ends that are connected to this drive then at the two ends that pontic is disconnected get final product again.Power set sail out of or drive towards the pontic except driving the monomer boat, and are also helpful when the dismounting screw rod, if there are not power set, pontoon bridge is under the water impact effect, the dismounting of screw rod is very difficult, and the use of power set can overcome flow action, makes the dismounting of screw rod become relatively easy.
In view of the bourn acting force at offshore place less relatively, left bridge canned paragraph or right bridge canned paragraph near the korneforos part by anchorage or with the bank regularly warping appliances such as ox be connected and fixed, the present invention when increase and decrease monomer boat, mobile two ends monomer boat near the bank often.
In order to satisfy the navigation demand, the present invention left side bridge canned paragraph and right bridge canned paragraph are arranged on the river course left and right banks, and left bridge canned paragraph is connected with the anchorage 3 that is fixedly arranged on upstream, river course or downstream by anchor cable 4 with partial monosomy boat in the right bridge canned paragraph also can be selected to be connected with the bank mooring facilities as the case may be.Form the navigation hole in the middle of left side bridge canned paragraph and the right bridge canned paragraph, the two ends of active segment 2 adopt the mode of removably connecting to form the continuous passage that crosses the river with left bridge canned paragraph and right bridge canned paragraph respectively, are provided with power set at active segment 2.Under the daily state, active segment 2 and left bridge canned paragraph and right bridge canned paragraph link together to constitute and can supply current integral body, namely as the pontoon bridge main body under the common pontoon bridge use state.After the connection between active segment 2 and the left bridge section/right bridge section was removed, active segment 2 just was in active state, can open and abdicate the navigation navigation channel, and this moment, the pontoon bridge main body can realize the function of opening the navigation or air flight.Navigation is closed active segment the pontoon bridge main body that namely is returned under the use state after finishing again.
Particularly, active segment has but is not limited to following two kinds of set-up modes (in these two kinds of set-up modes, its detail can be selected according to actual needs and flexibly):
One, downstream overlapping mode.This moment, active segment was positioned at the downstream of left bridge canned paragraph and right bridge canned paragraph, and the active segment two ends are overlapped on left bridge canned paragraph and the right bridge canned paragraph respectively and are connected by isolated plant (embodiment is wirerope 5).Join power set one cover, be located at active segment one end.Following to be located at the active segment left end with power set be how example explanation active segment opens and closes when navigation needs, and is located at the process all fours of the other end.When needing navigation, earlier open special-purpose linkage by the operating personnel on left bridge section and the right bridge section, put auxiliary constraint wirerope, the constraint wirerope of active segment left end need unclamp gradually with the movement of left active segment, after the active segment right-hand member is opened special-purpose linkage, the constraint wirerope suitably unclamp need behind the certain-length (this length enough makes active segment open when rotating not to interfere with right bridge canned paragraph as the rotating shaft end in generation and gets final product) fixed; The active segment left end is that the rotating shaft end is to a side shifting with the active segment right-hand member under power set and drag force effect, this moment, active segment was opened gradually, for prevent boats and ships by the time and active segment come in contact, the active segment left end of opening need move to right bridge canned paragraph place and adopt isolated plant affixed, guarantees the boats and ships safety of passing through.After boats and ships pass through, open the special-purpose linkage of active segment left end and right bridge canned paragraph, the active segment left end is back closed gradually under power set promote, and until the pontoon bridge main body that returns under the use state, whole navigation process is finished.
Two, center docking mode.This moment, active segment was positioned at left bridge canned paragraph and right bridge canned paragraph middle, and the two ends of active segment are docked at respectively on left bridge canned paragraph and the right bridge canned paragraph and by hinged bolt and are connected.Power set are two covers and are divided into the active segment two ends.It is the same to catch up with the situation of stating, in order to prevent unexpected the generation, be provided with the insurance wirerope that prevents that active segment is out of control between end and corresponding left bridge section or the right bridge section about active segment, the places different with the downstream overlapping mode are, open the bolt that active segment and left bridge section are connected with right bridge section, under two power set cooperation and under the drag force effect, the insurance wirerope can bear corresponding pulling force when opening, the active segment that is about to open is retrained.The active segment Parallel to the flow direction moves a certain distance, and active segment is opened when rotating not with interfering as the left side of rotating shaft end or right bridge canned paragraph in generation got final product.And then under the power drive of left side, the left end active segment is that the rotating shaft end carries out axial rotation with the right-hand member active segment, opens ship navigation fully until active segment with above-mentioned overlapping mode is the same.When closing, started the power set of left end by the operator, active segment is reached basic when parallel with canned paragraph, restart the right-hand member power set, under the cooperation of two power set, active segment is slowly started to left bridge canned paragraph and right bridge canned paragraph middle, will connect set bolt then, recover the pontoon bridge main body under the use state, vehicle and pedestrian can normally pass a bridge.
Center docking mode pontoon bridge does not intersect section, and good integrity makes things convenient for vehicles and pedestrians, but cost is higher, and it is longer that mobile active segment opens and closes the time that spends.The downstream overlapping mode, because active segment is overlapped on the downstream, the traffick difficulty crosses the river and does not have problems but be used for the pedestrian, and advantage is that cost is low, and it is shorter relatively that active segment is opened the shut-in time.
Described power set are the ship on-hook, are installed on bridgepile boat 7 stern trimming flags.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
