Abstract
The utility model discloses a culvert pipe, which is characterized in that the external pipe wall of a culvert pipe is wavy. The cross section of the culvert pipe is in flat oval shape. Since in the utility model, the external pipe wall of the culvert pipe is designed to be wavy, and the cross section of the culvert pipe is in flat oval shape, the diameter of the culvert pipe can be greater than 4 meters, and the effective water passing area is large, the culvert pipe has beautiful appearance and quick construction, low demand for the height of a road bed. The culvert pipe is suitable for urban roads and flat area highways to use, in particular to soft soil areas where the soft soil foundation does not need to be processed. The culvert pipe has simple structure, low cost, high site operation speed and short time, and is favorable for industrialization production.
Description
Technical field:
The utility model relates to a kind of road bridges and culverts facility, and the foot bridge in the engineerings such as particularly a kind of highway, municipal administration is contained the culvert pipe in the facility.
Background technology:
In highway, urban road engineering, all can run into the problem of crossing over creek.At present, common bridges and culverts structure is reinforced concrete box culvert or Reinforced Concrete Bridge.When on soft foundation, building culvert of reinforced concrete especially, generally to adopt sand-gravel pile or measures such as lime pile or cement mixing pile or concrete pile that ground is reinforced; When on soft foundation, building the steel concrete foot bridge, then need adopt the steel bar concrete pile plinth.Be difficult for compacting owing to contain back filling behind abutment soil, usually can occur the bigger distortion of roadbed behind bridge (culverts) platform after being open to traffic soon, the generation bumping at bridge-head influences traffic safety and comfortable.Simultaneously, the structure of reinforced concrete duration is longer.
Summary of the invention:
The purpose of this utility model is to provide a kind of culvert pipe, and it need not carry out Soft Ground in soft clay area, can accelerate speed of application.
To achieve these goals, the technical solution of the utility model is: a kind of culvert pipe is characterized in that: the outer tube wall of described culvert pipe is a corrugated, and the section of culvert pipe is a flat ellipse.
The utility model is owing to the outer tube wall with culvert pipe is designed to corrugated, the section of culvert pipe is flat ellipse, its diameter can be greater than 4 meters, effective big, handsome in appearance, quick construction of the cross-section of river, low to the roadbed requirement for height, be adapted in urban road and plains region highway to use, particularly soft clay area need not carried out Soft Ground.The utility model is simple in structure, is beneficial to suitability for industrialized production, and cost is low, and site operation speed is fast, and the time is short.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the partial enlarged drawing of Fig. 1
Fig. 3 is the structural representation of backing plate
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model is a kind of culvert pipe, it is characterized in that: the outer tube wall of described culvert pipe is a corrugated, the approximate flat ellipse that is of the section of culvert pipe, the tube wall of culvert pipe adopts the corrugated steel 1 and the double bolt 2 of at least two kinds of different curvature to be formed by connecting, backing plate 3 is equipped with in the junction of corrugated steel and bolt, and the resistance to compression degree of corrugated steel is much higher than general steel plate.Two backing plates 3 are equipped with in the junction of corrugated steel 1 and bolt 2 in the enforcement, and backing plate is provided with concave curvatures or the convex surface that matches with the curvature of corrugated steel.Present embodiment is coupled to the flat ellipse culvert pipe with at least six corrugated steels of different curvature with high-strength bolt, two backing plates up and down are equipped with in the junction of corrugated steel and bolt, upper padding plate is provided with the concave curvatures that matches with the curvature of corrugated steel with the contact surface place of corrugated steel, and lower bolster is provided with the convex surface that matches with the curvature of corrugated steel with the contact surface place of corrugated steel.This culvert pipe both can will be transported to the building site again at factory's batch making, also can after a section culvert pipe is finished assembly unit, adopt backfill to construct then the field fabrication that is connected between the corrugated steel, guaranteed bellows and native acting in conjunction.
