Bridge formwork construction is an important link in bridge construction. In order to ensure the quality of the whole bridge to meet the rigid requirements, there must be clear standards for formwork materials and bridge components. Materials and bridge components shall be tested for hardness and strength to ensure that the materials selected meet the design standards, so that the bridge can be used safely in real life.
Bridge template production due to the bridge type is different, in the production of templates will also be different. For the special-shaped steel formwork of large infrastructure such as railway, highway, road and bridge, such as column, beam, wall, etc., its production process is different from that of general combined steel formwork. This type of steel formwork is generally provided by the construction unit, produced according to the design drawings and provided by the manufacturer.
In order to make a good bridge formwork, in addition to the strict and meticulous requirements of the material selection process, the process should also be optimized as much as possible to ensure that the quality of the template is as qualified as possible. In the production process, the scientific production process can try to avoid defects in each link of the bridge template, so as to ensure the quality of the template as much as possible.
Affected by the current technical conditions, there are still the following problems in the construction technology of bridge formwork in China:
1. The utilization rate of formwork does not meet the relevant requirements and standards, resulting in a substantial increase in construction costs and serious cost waste.
2. At present, the template is mainly leased, which cannot guarantee that the quality of the template meets the relevant specifications and construction technical requirements.
3, for different bridge structure types and different structural parts of the bridge, has not yet formed a set of template construction technology system from the early template construction calculation to the late template construction management is more perfect.
4. In the bridge project that has been completed and under construction, the traditional formwork type will still be used, resulting in serious deformation and pitting of the formwork.
5, serious environmental pollution, in the construction process, due to the unreasonable use of the template, resulting in a serious waste of resources, causing serious pollution to the surrounding environment.
