Description
Technical field
The present invention relates to building engineering fields, specifically, the present invention relates to culvert structure and its construction methods.
Background technique
Culvert structure is widely used in construction fields such as municipal administration, mines, but for a long time there is the construction period it is long,
Formwork is difficult, intensity is lower, cannot bear the disadvantages of heavy vehicle load, restricts the progress of entire levelling of the land and construction.
Culvert mainly has several ways below in previous engineering:
1. reinforced concrete rectangular culvert, structure outer profile is rectangular cross section, and inside is similarly rectangular cross section, and when construction needs
Inner template and exterior sheathing are set simultaneously, need to be completed to concreting, after reaching design strength, removes inner and outer template, is formed
Last culvert finished product.It is required to setting template inside and outside reinforced concrete rectangular culvert, reaches design strength to casting concrete
Form removal afterwards, heavy workload, especially inner template, when culvert is longer or culvert size is smaller, Demolition Construction is difficult.
2. armored concrete prefabricated pipe culvert, using buried, formation culvert after the splicing of armored concrete prefabricated pipe.But it is prefabricated
Water-proofing treatment is difficult at tube seam, and there are risk of leakage.
3. zinc-plated bellows culvert, using the buried rear formation culvert of zinc-plated bellows.Zinc-plated bellows culvert directly with soil
Body contact, antiseptic property is poor, and bearing capacity is lower, is unsuitable for the current heavier vehicle in top.
In conclusion existing culvert and its construction method still have much room for improvement.
