Description

Technical Field

[0001] The invention relates to the technical field of auxiliary devices for water conservancy box culvert construction, and in particular to a template trolley for water conservancy box culvert construction. Background Art

[0002] In modern water conservancy projects, box culverts, as an important underground passage structure, are widely used in water supply, drainage, traffic tunnels and other projects. The quality and efficiency of box culvert construction are directly related to the safety and progress of the entire water conservancy project. The traditional box culvert construction method usually adopts on-site template and support system for concrete pouring. However, this construction method has the following shortcomings: low construction efficiency: the traditional template erection and dismantling process is cumbersome, requiring a lot of manpower and material resources, and the construction period is long, which is difficult to meet the needs of rapid construction; high safety risk: during the on-site construction process, the template and support system are less stable, and it is easy to have safety accidents such as template shedding and support structure instability; quality control is difficult: due to the limitations of on-site construction conditions, the positioning and fixing of the template are difficult to meet the precise requirements, resulting in box culvert size deviation and uneven surface, affecting the structural quality and appearance; large environmental impact: the noise, dust and waste generated at the construction site pollute the surrounding environment; cost control is difficult: in the traditional construction method, the template and support materials are mostly disposable, and the material waste is serious, resulting in high construction costs. In the existing technology, there is an urgent need for an efficient, safe and environmentally friendly template trolley for water conservancy box culvert construction.

[0003] Based on the above, most of the current formwork trolleys have poor adaptability, and the formwork of the formwork trolley is difficult to be tightly and stably positioned and fitted with the surrounding construction structure. After the construction of the water conservancy box culvert is completed, the formwork trolley is difficult to quickly detach and recover. At the same time, the structure of the formwork trolley is complex, and the operation and maintenance are difficult. The movement and positioning accuracy of the formwork trolley is not high, which affects the accuracy and quality of the box culvert construction. Summary of the invention
