Abstract

The utility model relates to a high-strength plastic reinforced composite engineering band, which mainly solves the defects that the existing reinforced engineering band is easy to crack along a lateral pressure tank and the friction force along the transversal direction is smaller. The high-strength plastic reinforced composite engineering band is composed of a plastic composite band, a longitudinal stiffening rib which is wrapped in the plastic composite band, a friction convex strip which is arranged on the both surfaces of the plastic composite band, the pressure tank, etc. The friction convex strip and the pressure tank are intermittent and dislocated. The high-strength plastic reinforced composite engineering band which is not easy to crack has long service life, and the high-strength plastic reinforced composite engineering band can be suitable for reinforcing the soil body in the dam body, the road bed, and the base of the other building structures.

Description

High strength plastic composite band

The utility model belongs to a kind of employed member when the soil body in dam body, roadbed or other building structure basis is strengthened, the composite reinforced engineering band of a kind of high strength plastics of more specifically saying so.

The soil body in dam body, roadbed or other building structure basis can produce local relatively moving stressed when big, thereby influence the stability of dam body, roadbed or building foundation, so in the construction of these engineerings, need strengthen the stressed bigger soil body usually.The most frequently used strong method that adds is to be provided with to strengthen the engineering band in the soil body, by the rubbing action between the soil body and the reinforcement engineering band locomotivity in the soil body is passed to reinforcement engineering band, have advantages of higher tensile strength because of strengthening the engineering band, so just improved the bulk strength of the soil body.

In the prior art, reinforcement engineering band commonly used mainly contains three kinds: a kind of is the engineering band that is made of plastics fully, its shortcoming is that elongation at break is big, tensile strength is low, just must use a large amount of plastic engineering bands for guaranteeing its reinforcement quality to the soil body, easily increase construction costs, thereby also now made it and strengthened application in engineering at the soil body; Second kind of steel band that is the surface through specially treated, but the cost of steel band is too high, can improve engineering cost greatly, and corrosion easily, therefore use seldom; The third then is the plastics composite band that is surrounded by reinforcing rib, for improving the skin friction of band, usually be equipped with horizontal parallel raised line, but its shortcoming has two: one, because of the surperficial indent between the parallel raised line is straight continuous perforation shape, the i.e. straight another side that extends to from one side of plastics composite band, and the plastic layer that should locate is less, like this when the stressed bending of composite plastic band, be easy to break from indent, and the reinforcing rib that wraps in is wherein exposed, this has not only destroyed the structure of band, and has shortened the application life of band; The 2nd, be straight continuous perforation shape along horizontal parallel raised line and indent therebetween, because of its frictional force transversely less, after using on the engineering, be easy to along the slippage of indent direction the frictional force between the influence band and the soil body when being close to its surperficial earth stress.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides and is difficult for after a kind of bending breaking and the composite reinforced engineering band of high strength plastics that skin friction is bigger.

For finishing above-mentioned purpose, the utility model provides a kind of high strength plastics composite reinforced engineering band, it comprises a plastics composite band, be wrapped in the waling in this plastics composite band, the surface of described plastics composite band is provided with friction raised line and the indent between the friction raised line, its special character is that described friction raised line and indent are crooked or are interrupted the friction raised line and the indent of dislocation.

Friction raised line and the arrangement position of indent on plastics composite band two surfaces crooked or the interruption dislocation can stagger mutually described in the utility model, also can be consistent with each other, but to stagger mutually for better, because can better avoid like this when indent is in the same position on band two sides, and band is broken along the indent position when bending.So-called staggering mutually is meant when the one side of plastics composite band is the friction raised line, then just in time is indent in the another side same position of being with, otherwise when one side was indent, the same position of another side then just in time was the friction raised line.

Reinforcing rib of the present utility model can be the glass fiber reinforcing rib, various wire reinforcing ribs, glass fiber and compound reinforcing rib wiry etc., but to adopt the glass fiber reinforcing rib serves as better, because adopt this reinforcing rib can make the engineering band have higher pliability.

Waling in the utility model to be evenly to be wrapped in the plastics composite band to well, can make like this engineering band to hold force rate more even, whole tensile strength is higher.

Because the friction raised line in the utility model is bending or is interrupted the dislocation shape, therebetween like this indent also is bending accordingly or is interrupted the dislocation shape, can find out thus, first advantage of the present utility model is: not only can avoid the engineering band to break along horizontal indent when stressed bending, prolonged the application life of engineering band; Second advantage is: increased frictional force transversely, after using on the engineering, be difficult for when being close to its surperficial earth stress having improved the skin friction of engineering band on the whole along the slippage of indent direction.

Referring to Fig. 1～3 as can be known, the composite reinforced engineering band of these plastics has a polyolefin plastics composite band 1, be enclosed with seven evenly distributed walings 3 in this plastics composite band 1, described reinforcing rib 3 is made of glass fiber, be provided with the friction raised line 2 of interruption dislocation and therebetween indent 4 on the surface of described plastics composite band 1, this friction raised line 2 and indent 4 just in time stagger mutually at the arrangement position on 1 liang of surface of plastics composite band.

Know referring to Fig. 4, Fig. 5, this embodiment also has a plastics composite band 1, wherein be enclosed with seven evenly distributed glass fiber reinforcing ribs 3, be provided with crooked friction raised line 5 and therebetween indent 6 on two surfaces of described plastics composite band 1, this friction raised line 5 and indent 6 just in time stagger mutually at the arrangement position on 1 liang of surface of plastics composite band.
