The invention provides a suspension bridge with a packsaddle paraboloid space mixing cable system. The suspension bridge comprises bridge towers, parallel wire ropes, packsaddle paraboloid cable nets and space stay cable nets, wherein each bridge tower comprises a portal type frame column, a parabola-shaped tower cap and tower cap supporting oblique cylinders; the parallel wire ropes are hung between the bridge towers; the end parts of the parallel wire ropes are fixed through an anchorage; each packsaddle paraboloid cable net is a space cable net formed by the sinking of a packsaddle paraboloid space net, and is coated on the parallel wire ropes; a plurality of steel structure curved beams are also arranged on the packsaddle paraboloid cable nets I, and the parallel wire ropes, the packsaddle paraboloid cable networks and the steel structure curved beams are fixed through a corresponding fixture; the space stay cable nets are respectively arranged on two sides of the parallel wire ropes; and the upper end of each space stay cable net is anchored in the corresponding tower cap supporting oblique cylinders, and the lower end of each space stay cable net is connected with the corresponding reinforced steel girder. The suspension bridge disclosed by the invention has the advantages of being high in spanning capacity, high in structural space rigidity, good in wind resisting stability, convenient to construct and the like, so that the problem of the wind resisting stability of an extra-large span suspension bridge is fundamentally solved.

The invention discloses large-span multifunctional roboticized engineering construction equipment and belongs to the technical field of civil engineering construction mechanical equipment. The large-span multifunctional roboticized engineering construction equipment comprises a plurality of supporting stand columns, steel wire rope driving units, steel wire rope guide devices, steel wire ropes, a controller and an end effector. The steel wire rope driving units, the steel wire rope guide devices and the steel wire ropes are matched with the supporting stand columns. The multiple supporting stand columns are arranged around the construction area, and a hydraulic cylinder is arranged in each supporting stand column to achieve ascending and descending of the supporting stand column in the vertical direction. Each steel wire rope driving unit is fixed to one side of the corresponding supporting stand column. The steel wire rope guide devices are arranged at the top ends of the supporting stand columns. One end of each steel wire rope is connected with the corresponding steel wire rope driving unit, and the other end of each steel wire rope penetrates the corresponding supporting stand column to be connected with the end effector after reaching the corresponding steel wire rope guide device. Remote control over the end effector is achieved through the controller, the large-span multifunctional roboticized engineering construction equipment can do wide-range large-span three-freedom-degree motion, the corresponding end effector is used in cooperation, and the work of punching and piling, wall breakage, pavement reconstruction and material carrying is completed.

The invention provides a thin-walled cylindrical soil core pile with wings. The thin-walled cylindrical soil core pile can serve as a supporting body and a temporary facility such as emergency hydraulic rescue, the thin-walled cylindrical soil core pile is made of metal, the middle of the soil core pile is a thin-walled cylinder, a front wing plate and a rear wing plate are arranged at the front end and the rear end of the thin-walled cylinder respectively, a fastening portion is arranged on the front wing plate and used for splicing with a rear wing plate of a front pressing pile in a guiding manner, and a sharp edge is arranged at the bottom of the pile, so that the pile can be smoothly pressed into soil. Various thin-walled cylindrical soil core piles can be sequentially pressed into the soil in a section divided manner, so that the front of one soil core pile is connected with the tail of other soil core pile to form an entire soil core pile, the soil core pile serves as the supporting body when soil is excavated, space stiffness of the pile cylinder and stability of the supporting body are improved by combined actions of the closed thin-walled cylinder, the two wing plates of the pile and a soil core, soil can not be reconstructed, so that surrounding residents cannot be disturbed, construction cost is reduced, the pile can be drawn out after supporting is finished, the pile can be repeatedly used, labor and materials are saved, and environments are protected.

The invention discloses a long-span space cable-net system suspension bridge, which belongs to the field of civil engineering. The long-span space cable network system suspension bridge mainly includes arched bridge towers, main cables, suspenders, parallel cables, space cable nets, back cables, arched ring beams, stiffened steel beams, anchors, caps and pile foundations. and other structures. The invention uses Bezier curves to optimize the traditional portal bridge tower, making its line shape more smooth and more likely to meet the anchoring requirements of the space cables; the space cable network is arranged in the form of a hyperbolic paraboloid, which effectively improves the cable system. At the same time, the excellent mechanical properties of the single leaf hyperboloid are used to improve the shape of the traditional pile foundation, and the anti-overturning performance is significantly improved under the condition of ensuring its bending and shearing bearing capacity. The long-span space cable-net system suspension bridge proposed by the present invention can greatly improve the wind resistance stability of the suspension bridge, and can be used as a reference for the construction of the long-span space cable-net system suspension bridge.

The invention belongs to the technical field of bridges, and discloses a glass suspension bridge with a ring suspender and a welded hollow ball node stiffened beam glass suspension bridge. The ring suspender and welded hollow ball node stiffened beam glass suspension bridge provided by the embodiment of the invention adopts an audio pattern as the design features. The concept of space-time tunnel is introduced in the architecture and landscape, and the circle with changing diameter is used to reflect the outside of the pedestrian passage, and tourists seem to be walking in the suspended space-time tunnel. Or for the call of the original hometown, the sound waves echoed among the distant mountains. The circular suspenders and welded hollow ball joint stiffened beam glass suspension bridge provided by the embodiment of the present invention adopt various plane and space changes, so that tourists can experience different space changes while traveling, and reduce the visual fatigue of crossing the super-long bridge body. The fun of the glass corridor bridge is increased, and visitors can feel the charm of nature and the stimulation brought by the volley when they are in the high sky framed by transparent glass.
