Abstract
The utility model belongs to a precast concrete culvert with an arc-shaped bottom and an arch-shaped top cover. The precast concrete culvert comprises an arc-shaped bottom plate (7), a left wall (1) and a right wall (6), and is characterized in that a top cover (3) is made into arch-shaped. Because the top cover (3) is made into arch-shaped, the precast concrete culvert with the arc-shaped bottom and the arch-shaped top cover is high in stress and long in service life, and bears high pressure.
Description
Technical field
The utility model belongs to building unit, arcuate bottom, the concrete prefabricated culvert of arch top cover that urban operating mechanisms such as particularly a kind of city underground pipe gallery, electric power tunnel use.
Background technology
Along with the continuous development of urban construction,, have higher requirement to fixation means such as the underground pipe gallery in city, electric power tunnels; A large amount of in the last few years popularizations concrete prefabricated Fang Han, the square-folded Fang Han that these are common structurally exists weak point; Particularly some local underground pipe gallery or electric power tunnel, it is very dark to require to be embedded in the underground degree of depth, certainly will will bear very big pressure to prefabricated culvert like this; The special easy fracture of the top cover of prefabricated culvert damages, and influences application life.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide that a kind of to bear pressure big, the arcuate bottom of long service life, the concrete prefabricated culvert of arch top cover.
The technical scheme that the utility model technical solution problem is adopted is: a kind of arcuate bottom, the concrete prefabricated culvert of arch top cover, comprise curved plate, Zuo Bi and You Bi, and it is characterized in that top cover processes arch.
The beneficial effect of the utility model is: arcuate bottom, the concrete prefabricated culvert top cover of arch top cover are designed to arch, and stressed good, it is big to bear pressure, long service life.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the front view of arcuate bottom, the concrete prefabricated culvert of arch top cover.
Fig. 2 is the left side view of Fig. 1.
Among the figure: the wall of a 1-left side; 2-steel strand tension hole; The 3-top cover; The 4-suspension ring; The 5-taper receives mouth; The right wall of 6-; The 7-conical bottom board; The 8-cone-shaped plug.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of arcuate bottom, the concrete prefabricated culvert of arch top cover comprise curved plate 7, left wall 1 and right wall 6, it is characterized in that top cover 3 processes arch.An end of containing is processed taper and is received mouth 5, and the other end is processed cone-shaped plug 8; During installation; The taper that cone-shaped plug 8 is inserted into another culvert receives in the mouth 5, and culvert is provided with five steel strand tension holes 2, is through in the steel strand tension hole 2 with steel strand and vertically strains adjacent culvert; Be fixed with suspension ring 4 above the top cover of containing 3, supply to install, carry and hang use.
Arcuate bottom, the concrete prefabricated culvert top cover 3 of arch top cover are processed arch; Curved plate 7 is again that arc is stressed good; Be provided with the phenomenon that stress is concentrated, long service life is the culvert that a kind of welcome a kind of city underground pipe gallery, electric power tunnel etc. are selected for use; Be specially adapted to the city of north cold area, need buried underground pipe gallery or tunnel requirement.
