The utility model relates to the field of bridge construction and can be used in the construction of road cable-stayed drawbridges, usually in cities across wide navigable rivers. The technical objective of the utility model is to reduce material and financial costs for the construction of a cable-stayed drawbridge, as well as to use all the hollow pylon struts in the navigable span simultaneously and as lifting supports for the vertical movement of the drawbridge to the design level. The technical problem is solved due to the fact that a cable-stayed vertical lift bridge, consisting of cable-stayed girder spans, has a vertical lift span and two pylons with four hollow racks in the navigable span, differs in that all pylon racks in the navigable span are used as lifting supports, inside of which there are counterweights, traction winches and rope-pulley systems for moving the span upwards. In this case, all the pylon posts at the top are rigidly connected to each other along the facade and across the bridge by horizontal metal beams, which are used as pedestrian bridges. At the same time, people are lifted onto them by special observation elevators located outside all pylon posts.
The utility model relates to the field of bridge construction and can be used in the construction of road cable-stayed drawbridges, usually in cities across wide navigable rivers.
Various designs of large and extra-class cable-stayed fixed bridges across wide and deep navigable rivers and straits are known (Byte bridges. A.A. Petrovsky and others - M.: Transport, 1985. Metal bridges. N.N. Bychkovsky, A.F. Dankovtsev. In 2 parts. Saratov, 2005. In 2 kN. P.M. Salamakhin and others. - Academy, 2008. Journal of bridge construction. ).
To ensure a navigable height clearance (up to 70 m or more), high supports are built, which requires significant material and financial costs for the bridge itself and for the construction of long overpass structures to them in order to provide the design slopes for vehicle access to the bridge. However, such solutions are not always possible due to the lack of necessary territories, especially in the cramped conditions of urban development on the banks of a water barrier.
The design of a metal cable-stayed single-pylon drawbridge is also known (Patent for utility model 118319 dated July 20, 2012 “Metal cable-stayed single-pylon drawbridge”), in which the part of the cable-stayed beam span (VBPS) above the shipway, adjacent directly to the pylon, is opening by rotating it upward around a horizontal axis using counterweights of a rope-pulley system and traction winches. These elements are placed inside both hollow pylon posts (reinforced concrete or metal).
The main disadvantage of a cable-stayed bridge is the following: during the erection of the bridge, the fixed part of the VBPS is kept from horizontal shift by its cables to the pylon with a special rigid metal stop placed in the bridge abutment. In addition, the fixed part of the VBPS in the open position of the bridge may have (like a cantilever) significant transverse vibrations (amplitudes) when exposed to wind, which will complicate the process of disconnecting and connecting the adjustable and fixed parts of the VBPS. The consequence of this may be the impossibility of raising the bridge in strong winds.
There are also known designs of vertical lift bridges (for example, across the Neva, Northern Dvina, Svir and other rivers), in the navigable spans of which there are beam spans and two lift towers with elements of a rope-pulley system and guides for the vertical movement of the span. buildings [Drawbridges. V.I. Kryzhanovsky - M.: Transport, 1967].
The main disadvantage of the vertical lift bridge adopted as a prototype is the limitation of the navigable clearance in height. When the height of the towers is greater than the width of the navigable span, such bridges become unprofitable due to the high cost of installing lifting towers.
The technical objective of the utility model is to reduce material and financial costs for the construction of a cable-stayed drawbridge, as well as to use all the hollow pylon struts in the navigable span simultaneously and as lifting supports for the vertical movement of the drawbridge to the design level.
The technical problem is solved due to the fact that a cable-stayed vertical lift bridge, consisting of cable-stayed girder spans, has a vertical lift span and two pylons with four hollow racks in the navigable span, differs in that all pylon racks in the navigable span are used as lifting supports, inside of which there are counterweights, traction winches and rope-pulley systems for moving the span upwards. In this case, all the pylon posts at the top are rigidly connected to each other along the facade and across the bridge by horizontal metal beams, which are used as pedestrian bridges. At the same time, people are lifted onto them by special observation elevators located outside all pylon posts.
The utility model is illustrated in the drawing, where in FIG. Figure 1 shows a diagram of a fragment of a cable-stayed bridge with a navigable span, where it is indicated:
a - section of the pylon stand with a counterweight placed in it, a traction winch and a rope-pulley system for lifting the span;
b - general view of the bridge façade of the pylon strut with the cables of the fan system and the observation elevator;
c - cross section of the bridge in the navigable span;
d - top view of the pylon support and parts of the lifting and cable-stayed beam spans;

9 - traction winch;
10 - support beam;
11 - pulley rollers;
12 - consoles for lifting (jacking) beams of the lifting span;
13 - supporting parts;
14 - pylon support.
Cable-stayed vertical lift bridge is an extended structure consisting of several cable-stayed-beam spans 1 and at least one vertical-lifting span 2 in the navigable span, as well as several pylon supports 14. The cable-stayed-beam spans 1 are supported by cables 3 of the fan system. The pillars of the pylons 4 at the top are rigidly connected to each other along the façade and across the bridge by metal beams.
A cable-stayed vertical lift bridge works as follows. The lifting span 2 moves upward using counterweights 8, traction winches 9, a rope-pulley system consisting of steel ropes (cables), various rollers 11, some of which are fixed on the support beam 10 and on four consoles 12 of the span 2.
In the lower (unraised) position, spans 1 and 2 rest on supporting parts 13 placed on pylon supports 14 of the navigable span.
During the raising of the bridge, pedestrians, as well as maintenance personnel, can move from one part of the bridge to another along stiffening beams 5, on which decking and railings are installed. Lifting people onto the tops of the pylon posts 4 is carried out by panoramic elevators 6, which are attached to the facade surfaces of the posts 4. Pavilions 7 (or canopies) with fences can be mounted on the tops of the posts 4. These pavilions (or canopies) can also be used as observation platforms.
The mass of counterweights, the power of winches, and pulleys are calculated based on data on the length and mass of the lifting span.
The utility model expands the scope of use of pylon struts and simplifies the design of supports in a navigable span.
1. Cable-stayed vertical lift bridge, consisting of cable-stayed girder spans and having a vertical lift span in the navigable span and two pylons with four hollow racks, characterized in that all pylon racks in the navigable span are used as lifting supports, inside which are placed counterweights, traction winches and rope-pulley systems for moving the span upwards.
2. Cable-stayed vertical lift bridge according to claim 1, characterized in that all the pylon racks at the top are rigidly connected to each other along the facade and across the bridge by horizontal metal beams, which are used as pedestrian bridges, while lifting people onto them is carried out by special observation elevators located outside all pylon posts.
The impressive Lower Hatea Crossing (Te Matau a Pohe) bridge was opened on 27 July 2013 by Whangarei MP Phil Heatley in New Zealand.
Lower Hatea Crossing is a 265 meter long and 17 meter wide highway bridge that crosses the Hatea River and connects Pohe Island and Port Road. It consists of nine middle spans of 25m each and two extreme ones of 20m each.
The bridge is two-lane, the width of each lane is 4.1 m, on one side of the bridge there is a pedestrian sidewalk 2.5 m wide, on the other side a bicycle path 3 m wide.
The bridge was built to ease congestion in the city center and improve access to Whangarei Heads and the airport, making it a key bridge on Whangarei's trunk road network. It is expected that it will handle up to 8,000 cars per day. The bridge project belongs to the English consulting company Knight Architects.
Te Matau a Pohe is movable, its 25m central span is raised when ships pass, but this is not done for all ships. Many boats pass freely under the bridge without raising the span. To allow vessels over 7.5m in height to pass, you must send a request via radiogram to raise the span or call. Vessels awaiting this lifting are moored to pontoons on either side of the bridge.
This swing bridge is a swing bridge, the first of its kind in New Zealand. Such bridges are quite rare outside the United States. This system was chosen because the required span opening clearance is achieved faster than in other drawbridges, due to the fact that the span rolls back and rotates at the same time. And such a quick rise reduces the waiting time for tourists on the bridge.
Since access to the bridge site was not easy, due to shallow water and tidal action that prevented the movement of large floating equipment, as well as limited road access to the site, the developers decided to use prefabricated and prefabricated modular elements that could be shipped and installed appropriate mechanisms.
The bridge is formed from precast concrete units, while the lift span consists of two steel structures: J-shaped beams that are mounted on an orthotropic welded steel slab and two cantilever slabs made of aluminum. The lightweight orthotropic slab is unique to New Zealand and reflects the international state of the art.
Thus, counterweights located at the top of the J-shaped beam maintain balance from the weight of the orthotropic slab and minimize the power required to lower the span.
The lifting span is driven by hydraulic cylinders, which have holes of 320mm, rods with a diameter of 280mm, a working stroke of 8380mm and a weight of 8 tons each.
These 400 ton span raising and lowering cylinders were made in Holland by the Eadon Corporation - one of the few factories in the world that can produce cylinders of this size and quality. Power is supplied to the cylinders by four 30 kW hydraulic units driving pumps.
The hydraulic cylinders are based on a support, which is reinforced with prestressed reinforcement extending down on both sides from monolithic V-shaped racks. The supports, in turn, rest on shell piles.
New Zealand is known for its earthquakes, so the bridge uses fixed connections between the bridge slab and the abutments and monolithic abutments, which have the added benefit of increasing stability on each side of the bridge. This design also has the advantage of helping to protect the bridge from the impact loads of ships. Most of the vessels currently used on the river are light, but in the future it is planned to operate 350t barges.
The lift span is designed to operate in stormy wind conditions, but the bridge is still not opened during stormy winds and during rush hours.
There are very few new swing-open bridges in the world, and even fewer that open using hydraulic cylinders. New Zealand has very few swing bridges at all and so this is a real achievement for their infrastructure. And the curved shape of the J-beams also has a cultural context and is interpreted as a “fish hook”, which is widely used in Maori culture. The shape is designed to be recognizable both day and night, providing a precise entrance to the urban water area.
The bridge was built by McConnell Dowell and Transfield.
The cost of the bridge was 32 million New Zealand dollars.
