Prefabricated segment assembly system
The segmental assembly template is a special mold with complex structure and high precision designed according to the prefabricated segmental assembly of bridges. It is mainly composed of outer mold, inner mold, bottom mold, end mold, hydraulic and electrical systems.
The system is divided into long-line and short-line methods according to different prefabrication methods, and divided into dry segment assembly and wet segment assembly according to different forms of seams.The formwork has sufficient strength, rigidity and stability. It can ensure the correctness of the design shape, size and mutual position of each part when it bears the gravity, lateral pressure of the newly poured concrete and various loads during the construction process.
Introduction to Trolley
Concrete lining trolley is an indispensable non-standard product for secondary lining during tunnel construction. It mainly includes simple lining trolley, fully hydraulic automatic walking lining trolley and grid-frame lining trolley. According to different functions, it can be divided into two lining trolley, spray maintenance trolley, waterproof board trolley, steel trolley, hydraulic self-propelled trestle, etc.
Hydraulic box girder
Box girder template is a special non-standard equipment for making box girder, which plays a great role in controlling the production speed and surface quality of box girder. Most of the initial formwork was made of loose wood panels. At present, due to the rapid development of the national economy, the construction of railways and highways has developed rapidly. The large-scale bridges have forced the extensive use of steel formwork in the prefabrication of bridges. Steel formwork box girder The template has the characteristics of less seams, high rigidity, and flat surface. Although the traditional assembled steel formwork box beam formwork also has the characteristics of fewer seams, high rigidity, and flat surface, the erection and demolding of the formwork are all manually installed and disassembled, requiring a lot of manpower and low construction efficiency. This makes the liquid template come into being. The hydraulic system is used to control the erecting and closing of the template, and there is a special spreader for lifting, which saves a lot of labor, greatly improves the construction efficiency and shortens the construction period.
Hanging basket
Hanging basket is the main equipment in cantilever construction. According to the structure, it can be divided into truss type (including flat-string unbalanced weight type, rhombus, triangle, bowstring type, etc.), diagonal type (including triangular diagonal type and prestressed diagonal type) Type), steel type and mixed type 4 types. According to the requirements of concrete cantilever construction technology and design drawings for the hanging basket, comprehensively compare the characteristics, weight, steel type and construction technology of various forms to determine the structure of the hanging basket; the hanging basket construction does not occupy the road at all, and there is no need to interrupt the main The auxiliary road traffic relies on the movement of the "hanging basket" to make the concrete box girder poured on site be produced in the "hanging basket". The construction personnel pour 2-4 meters long each time. After the bridge body is hardened and reaches sufficient strength, the hydraulic device will Push the hanging basket forward, and then pour a new section of beam.
The design principles of the hanging basket: light weight, simple structure, strong and stable, easy to move forward and easy to assemble and disassemble, strong reusability, small deformation after stress, etc., and sufficient space under the hanging basket can provide larger construction operations The surface is conducive to the construction operation of steel formwork.
Bridge static load test bench
The static load test bench is the main equipment for the static load bending test of the whole hole prefabricated box girder and T beam. Our company has produced universal rod assembly and half-box test benches for many years, which can meet the static load bending test requirements of double (single) line whole-hole box girder and T-beam with spans of 32m, 24m, and 16m. According to the actual needs of the static load test, a variety of beam-shaped general static load test benches can be designed and manufactured, which greatly saves users' static load test expenses.
