Hebei Kaixiang bridge expansion joint manufacturer explains the construction steps 1

&This process is suitable for on-site pouring and prefabricated concrete structure projects in urban bridge projects, and the construction of arches and brackets in masonry wastewater treatment plants.
Construction preparation
Material requirements
The raw materials required to make the formwork (steel plates, steel sections, steel castings, wood, plywood, plastic boards and other materials) should
comply with current national standards and regulations. Construction organization design requirements.
.The materials, specifications, and
models of steel sections, steel pipes, connectors, welding parts, and embedded parts used in the formwork and arch support systems should comply with the design requirements and relevant standards.
..Construction machinery and equipment
.Formwork, bracket and arch processing and production equipment, and welding equipment.
.Vehicles for transporting formwork, brackets and arches, formwork hoisting machinery (cranes, tower cranes), formwork lifting equipment (hydraulic oil pumps, oil cylinders, jacks, etc.), formwork installation tools (wrenches, crowbars, hand Hammer, etc.).
.Template inspection and testing instruments and tools (total station, theodolite, level, spirit level, line drop, backing ruler, square ruler,
box ruler, etc.)
..
Operating conditions
The roads on site are smooth, the construction site has been cleared and leveled, water and electricity are connected to the site, and night lighting facilities are available.
The required quantities of formwork, brackets and arches have been prepared and ready to go.
Before the support system (racking rack) is installed, the foundation (base, platform) must be solid and reliable, and the surface of the foundation must be cleaned.
Before the formwork is installed (support), the measurement and setting out have been completed.
..
.The investigation of underground structures has been completed and the protection measures for underground structures have been implemented.
Technical preparation
. Design of formwork, brackets and arches
) The design of formwork, brackets and arches should be based on the structural type, design span, load size (including wind load),
The types of foundation soil, construction methods, construction equipment, material supply and related design and construction specifications are carried out.
) The design of formwork, brackets and arches should include the following main contents:
Draw general assembly drawings and detailed construction drawings of formwork, arches and brackets
According to the structural constraints of the formwork, arches and brackets Under the action of construction load, the strength, stiffness and stability of the force system are respectively checked
The installation procedures for formwork, arch and bracket structures are compiled
