Description

Technical Field

[0001] The invention relates to the technical field of bridge accessory equipment, and in particular to an assembly anti-collision box and an anti-collision facility using the same. Background Art

[0002] At present, some special anti-collision facilities designed for specific working pier forms have good anti-collision effects, but most of them have a single design, poor versatility, long manufacturing and installation cycle, and high manufacturing, transportation and installation costs. Anti-collision facilities are mainly composed of several boxes. A single box includes a panel (the most representative is the ultra-high performance UHPC full-surround panel), an energy dissipation device, a box connection device, and a damping device.

[0003] Considering the different forms and anti-collision levels of bridge piers, the uncertainty of the design of the appearance of anti-collision facilities requires a single design with poor versatility. There are two casting processes when making and casting UHPC full-enclosed panels: the traditional top-down casting process is prone to defects such as hollowing, pitting, and bubbles; and the pumping pressure casting process, although the casting quality is good, has many problems such as large mold side pressure, high mold cost, and complex mold reinforcement process. For the anti-collision box of the passive anti-collision facilities with a pier defense level of more than 10,000 tons, the box size is too large or too large to be manufactured and transported in factories outside the project site. The project site basically has no factory construction conditions. Even if it is barely built, the investment cost is quite large, and it will eventually be abandoned because the gains do not outweigh the losses. Therefore, the existing UHPC full-enclosed panels have problems such as poor versatility, difficult quality assurance, and high production costs during production and manufacturing; in addition, after production, the box is often too wide and too high to be transported to the project site for enclosure and installation.

[0022] See also Figures 1 to 12 As shown, this embodiment provides an assembly crash box. Considering the intelligent manufacturing, production cycle and logistics transportation requirements of the assembly crash box, the assembly crash box is designed with panel modularization; the assembly crash box includes a crash box body, a module connection component, an anti-seepage mechanism and an energy dissipation element; the specific structure is as follows: The anti-collision box is composed of a plurality of plane modules 1 as the box panels, a plurality of two-sided corner modules 2 as the box frames, and a plurality of three-sided corner modules 3 as the top corners of the box. The plane modules 1, the two-sided corner modules 2, and the three-sided corner modules 3 are all made of UHPC materials; among them, the plane modules 1, the two-sided corner modules 2, and the three-sided corner modules 3 can be collectively referred to as panel modules. Figure 1 Take the anti-collision box in as an example, wherein each top corner of the anti-collision box is provided with a three-sided corner module 3, each edge of the anti-collision box is provided with a two-sided corner module 2, and the top panel, bottom panel and side panels of the anti-collision box are composed of the plane module 1, the two-sided corner module 2 and the three-sided corner module 3. A box installation opening 9 is provided on the top panel of the anti-collision box, and a box opening end cover plate 13 for sealing it is provided at the box installation opening 9. The box installation opening 9 is used for assembly of the anti-collision box, etc. In this structural setting, the module connection method between the plane module 1, the two-sided corner module 2 and the three-sided corner module 3 adopts a prestressed dry connection method.

[0023] In a specific embodiment, considering the water service environment of the anti-collision box, the combined connection between the panel modules adopts multiple water-stopping and anti-seepage, the gap between the connection components is sealed by plugging, and the panel boss adopts a multi-level notch and a special-shaped anti-seepage plate shielding design that extends the anti-seepage path, that is, an anti-seepage mechanism is provided at the connection seam of each two adjacent panel modules. Specifically, the inner wall surfaces of the plane module 1, the two-sided corner module 2 and the three-sided corner module 3 are all provided with a boss a for connecting between two adjacent (panel) modules, and the boss a is provided with an anti-seepage groove b, and the circumferential side walls of the plane module 1, the two-sided corner module 2 and the three-sided corner module 3 are all provided with a water-stop groove c. The two adjacent modules are fixedly connected by a module connection assembly, and an anti-seepage mechanism is provided at the connection seam of the two adjacent modules. The anti-seepage mechanism includes an anti-seepage pressing device and an anti-seepage strip 4; the anti-seepage pressing device includes a special-shaped anti-seepage plate 5, which is arranged across two adjacent bosses a of two adjacent modules, and is provided with an anti-seepage protrusion matching the anti-seepage groove b; a pressing plate 7 for pressing the special-shaped anti-seepage plate 5 is provided on both sides thereof, and the pressing plate 7 is fixedly connected to the corresponding boss a by a fastening bolt 8; a supporting balance bar 6 is provided between one end of the pressing plate 7 and the boss a, and a pad 10 is provided between the other end of the pressing plate 7 and the special-shaped anti-seepage plate 5. Figure 4 As shown, the anti-seepage strip 4 is arranged in the accommodation space formed by two oppositely connected water stop grooves c inside the connecting seam of two adjacent modules.

[0024] In a specific implementation, the panel module connection is designed as a flat docking method, which effectively reduces the difficulty of anti-seepage and maintains the rationality of the structure. The connection between planes, top (bottom) surfaces and side surfaces, and top (bottom) surfaces and two adjacent side surfaces can be completed by combining the following three types of panel modules, namely, plane modules, two-sided corner modules, and three-sided corner modules. The size of the panel module is controlled within the allowable range of transportation. The style of the module is determined according to the shape of the anti-collision box panel, which can be either a plane or a corner. Corner modules include two standard modules: two-sided corner modules and three-sided corner modules. See the attached for details. Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10 .

[0025] In a specific embodiment, the panel modules are connected as a whole through suitable pressure-bearing connectors, and the connection seams are anti-seepage through multiple seals designed for installation and extended anti-seepage pathways. The connection seams of the panel modules can be single seams or T-seam seams. Fig.11 , Attachment Fig.12. Each two adjacent panel modules are connected by a module connection assembly, and the module connection assembly includes a connecting rod 11 and two locking nuts 12. Specifically, a plurality of connection holes are spaced apart on the two adjacent bosses a of the two adjacent modules, and a connecting rod 11 is installed through each connection hole. Two locking nuts 12 are arranged at both ends of the connecting rod 11, and are used to fix the two adjacent modules. Two water stop grooves c with a C-shaped cross section are provided on the circumferential side walls of the plane module 1, the two-sided corner module 2 and the three-sided corner module 3; the connection hole is arranged between the two water stop grooves c so that the anti-collision box can be better waterproof. The inner wall surfaces of the plane module 1, the two-sided corner module 2 and the three-sided corner module 3 are all provided with bosses a in the circumferential direction, and the bosses a and the inner wall surfaces of the modules in which they are located form a step structure with high periphery and low middle; the connecting hole is an arc-shaped hole that passes through two adjacent modules and connects the two bosses a, and the connecting rod 11 is an arc-shaped connecting rod that matches the arc-shaped hole; this structural setting can not only ensure the connection strength between the modules, but also facilitate the installation of the module connection assembly.

[0026] In a specific embodiment, taking into account the large honeycomb processing cost and the convenience of modular design, steel gratings, steel cylinders, or a combination of steel cylinders and independent honeycomb blocks are used inside the anti-collision box as energy dissipation elements (not shown in the figure). By adjusting the proportion and distribution of the various components of the energy dissipation elements, the anti-collision needs of different navigation levels can be met.

[0027] In a specific implementation, UHPC has 4 to 8 times higher compressive strength, 10 times higher flexural strength, 200 times higher fracture strain energy, about 30% higher wear coefficient, and more than 4 times higher impermeability than conventional concrete, compared with conventional concrete. It can achieve durability far exceeding that of metal and composite materials in river and ocean wave cyclic loads, high osmotic pressure, and strong ultraviolet environments; at the same time, its high flexural strength can provide the high specific strength characteristics required for the pontoon structure, and its high fracture toughness can achieve the coordinated deformation of the external box body and internal energy dissipation elements of the anti-collision facility to a certain extent, better serving the overall crashworthiness design.
