Abstract

The invention provides an assembly type hydraulic box culvert template and a construction method of a prefabricated assembly type box culvert of the assembly type hydraulic box culvert template, and belongs to the field of highway engineering construction. The assembly type hydraulic box culvert template comprises a template, a hydraulic power system and an adjusting support. The construction method comprises the steps that the assembly type hydraulic box culvert template is installed; the template is used; steel bars are machined and installed; a steel bar framework is hoisted put into the template; an internal mold is installed; the template is installed while concrete is poured; the concrete is poured; the concrete is cured; and the template is removed, and finally the prefabricated assembly type box culvert is prepared. The box culvert can be prefabricated in a centralized mode, and is installed on site, so that a lot of concrete is saved, the construction progress is accelerated,construction cost is reduced, damage and pollution to underground water and soil are greatly reduced, and the box culvert is especially prominent in green and environment-protecting aspects; and the entity quality of culverts is effectively improved, the yield of the appearance and a protection layer is greatly improved, and good economic and social benefits are obtained.

Description

technical field

[0001] The invention belongs to the field of highway engineering construction, and in particular relates to an assembled hydraulic box culvert template and a construction method for a prefabricated assembled box culvert. Background technique

[0002] Reinforced concrete cover culverts are mostly used in the construction of field expressways and first-class highways, especially in northern regions where the climate is cold and the effective construction period is short. Reinforced concrete cover culvert mainly adopts on-site binding of steel bars, supporting formwork, and pouring concrete. It needs to be cured for a long time before it can be put into use. The construction period is long, and it is greatly affected by weather conditions. Various accidents are likely to occur during excavation construction, causing personal and physical damage. Property security poses a huge hidden danger. Based on this, the prefabricated box culvert technology came into being...
