Abstract
This invention declares a fiber reinforced cement pipe with glass fiber reinforced plastic inner covering and outer protective layer. It is feathered by the cement mortar layer between the glass fiber reinforced plastic inner covering and outer protective layer, and the fiber reinforced cement mortar layer between the glass fiber reinforced plastic inner covering and the cement mortar layer, and/or the glass fiber reinforced plastic outer covering and the cement mortar layer. The mentioned fiber reinforced cement mortar layer is composed by the matrix of cement mortar wrapped repeatedly by the reinforced fiber. It alters the traditional design that lacks axial and circular tensile strength. This invention uses cheap fiber reinforced cement inner and outer structures and cement mortar layer instead of glass plastic fibers, which increases the performance of the product while reduces the cost.
Description
Technical field:
The present invention relates to a kind of supplying drainage, especially a kind of strong shock resistance, the fiber reinforcement cement pipe that cost is low.
Background technique:
At present, plumbing tubing mainly contains that steel pipe, ductile iron pipe, prestressed concrete pipe, Prestressed concrete cylinder pipe (PCCP), high density polyethylene (HDPE) are given, waste pipe (HDPE) and glass reinforced plastic sand pipe etc., uses commonplace with prestress steel cylinder concrete supply pipe (PCCP), high density polyethylene drainage pipe and glass reinforced plastic sand pipe especially.
Prestress steel cylinder concrete supply pipe (PCCP) is the composite pipe of steel cylinder and concrete for making; tube core is a concrete; thick 1.5mm steel cylinder is imbedded at outer wall or middle part at tube core, and on tube core, be wound with ring orientation prestress stretch-draw and twine High Tensile Steel Wire, and at its outside spraying cement mortar cover.The caliber of Prestressed concrete cylinder pipe is generally DN 600～3600mm, and working pressure is 0.4～2.0MPa, wherein is generally lined below the DN1200mm, is generally embed-type more than the DN1400mm, often is applied in DN〉in the long distance water diversion engineering of 1200mm.The characteristics of this pipe are that interface adopts steel bell and spigot, and size is more accurate, and is provided with rubber water-stop ring (single cushion rubber or two cushion rubber), thereby stagnant water effect is good; Owing to the effect of steel bushing, impervious ability is very strong again.But this tubing heaviness, is installed all inconveniently at transportation, as the concrete layer of tubing fine cracks is arranged, and underground water can be invaded and be corroded steel bar stress, causes the tubing compression resistance to descend, and finally causes tubing to damage.
The high density polyethylene drainage pipe claims the HDPE waste pipe again, can be divided into double-wall corrugated pipe (two kinds of DN200-DN800 and hollow wall entwining tube (DN200-DN3000), excellent properties such as light weight, corrosion-resistant, non-scaling, inner wall smooth, friction factor are little because it has, easy construction relatively are fit to municipal engineering rainwater, effluent discharge.Though the double-wall corrugated pipe comprehensive cost is lower, its birdsmouth is that single cushion rubber socket joint connects, joint socket place insufficient rigidity, be out of shape bigger, the leakage rate height; And the large diameter coiled pipe cost is higher and pipe fitting is difficult for supporting.
Glass reinforced plastic sand pipe claims glass fibre to strengthen thermosetting resin burning into sand pipe again, by the frp lining layer, glass fibre reinforced plastics inner structure layer, resin clip layer of sand and glass fibre reinforced plastics external protection constitute, in low, press in the case history of high external pressure, the positive pressure of the tube wall center near zone under the external pressure effect is very little, bear by the resin mortar layer, high stressed zone then twines the district by the pure fiber that is positioned at the tube wall both sides to be born, the designability of composite material and the characteristics of most its energy of thing have been demonstrated fully, although glass reinforced plastic sand pipe has good corrosion resistance, inner wall smooth (roughness coefficien is 0.009), hydraulic performance is good; High-strength light, easy for installation; The body good airproof performance, the characteristics that leakage rate is low, but owing to exist the high problem of tubing cost in actual applications, so its application also is restricted.
Summary of the invention:
The present invention is in order to solve the existing in prior technology technical problem, a kind of inner wall smooth to be provided, anti-corrosion leak-proof, good airproof performance, have higher anti-in pressure energy power and critical external compressive resistance ability, fiber reinforcement cement pipe with low cost.
Technical solution of the present invention is: a kind of fiber reinforcement cement pipe; frp lining layer 1, glass fibre reinforced plastics external protection 2 are arranged; described frp lining layer 1 has cement sand bed 4 with glass fibre reinforced plastics external protection 2; between frp lining layer 1 and the cement sand bed 4 or/and fibre reinforced cement slurry construction layer 3 is arranged between glass fibre reinforced plastics external protection 2 and the cement sand bed 4; described fibre reinforced cement slurry construction layer 3 is to be matrix with the compo, and twining yarn with fiber is that the compound winding of reinforcing material constitutes.
The present invention has changed existing glass fiber reinforced plastic sand-inclusion pipeline burning into sand layer does not provide (hoop, axially) the traditional design theory of tensile strength, glass fibre reinforced plastics inner structure layer and resin clip layer of sand have been substituted with cheap fibrous cement paste inner structure layer, glass fiber reinforced cement layer and fibrous cement paste external structure layer, and provide (hoop, axially) tensile strength, reduce the consumption of unsaturated polyester resin, in the index of enhancing product performance, reduced product cost.Rational cement slurry prescription can guarantee to mix with glass fibre winding yarn, associativity is good; and guarantee that cubical contraction and frp layer are approaching; can be combined as a whole securely with frp lining layer and glass fibre reinforced plastics external protection; have advantages of higher tensile strength, compressive strength, resistance to flexure and fracture elongation, barrier properties, anti-corrosive properties are strong.Owing to have impact resistance preferably, can prevent from work progress, body to be injured by a crashing object or press against and hinder the pipeline water flowing leakage phenomenon that occurs because of hard things such as stones, avoid the economic loss of therefore being brought.
Performance index of the present invention contrast as following table with prior art:
| Performance index | Tensile strength Mpa | Compressive strength Mpa | Resistance to flexure Mpa | Fracture elongation |
