Description
Technical field
The utility model belongs to plumbing building materials design and fabrication technology field, particularly inner lining glass fiber reinforced plastic concrete composite pipeline.
Background technique
In prior art, concrete reinforced pipe is to take the industrial products that cement makes through deep processing as base material, there is good Physical and mechanical properties, long service life, the characteristics such as maintenance expenses is few, in the liquid conveying engineering construction such as China town and country, industrial and mining enterprise, farmland cement and the energy, traffic, communication, be widely used, but traditional reinforced concrete sewer pipe also exists a lot of shortcomings; For example, impermeability is poor, the body friction factor is large, and flow velocity is slow, the anti-corrosive properties ability is poor, can only be for the draining drainage project.And existing glass fibre reinforced plastics and reinforced concrete composite pipe are mainly used in the liquid transportation art, but in prior art, glass fibre reinforced plastics adopts the increase cohesive forces such as protrusion rib, silica sand with the reinforced concrete interface transition, and interface is poor in conjunction with soundness.Although the glass fibre reinforced plastics supplying drainage possesses stronger antiseptic property, cost is too high, and bearing power is poor; And because simple glass steel and reinforced concrete multiunit tube joint are not to adopt integrated birdsmouth to be tightly connected at present, device for cleaning pipeline is crossed post-processed and is guaranteed sealing, construction is complicated, sealability is very undesirable, effect is also bad, and opposing pipe sedimentation poor performance, also can't carry out connector test.
The model utility content
The purpose of this utility model is to provide a kind of glass fibre reinforced plastics concrete composite pipeline, and this multiple tube is not only realized good interfaces transition in pipeline, and can reliably realize fast that excellent sealing is connected between pipeline and pipeline.This multiple tube also has the advantages such as environmental protection, corrosion-resistant, energy-efficient, with low cost, body good integrity, test be convenient.
The purpose of this utility model is achieved in that the inner lining glass fiber reinforced plastic concrete composite pipeline, comprises Glass Steel Tube, concrete layer and steel bar layer, and the head end of integrated Glass Steel Tube and end arrange respectively interface and bellmouth; Ring packing groove and pressure testing hole are set on interface; The bellmouth of Glass Steel Tube is broadening formation; Interface matches with bellmouth; To the Glass Steel Tube end, sandstone particle composite bed is set at the Glass Steel Tube outer surface from the interface tail end; Outer surface at sandstone particle composite bed arranges concrete layer, and steel bar layer is set in concrete layer.
The creationary technological points that the utility model is concrete: the one, by the composite effect of lining resin and sandstone particle layer composite bed assurance resin layer and reinforced concrete floor.Composite bed is composited by isophthalic unsaturated polyester resin or vinyl ester resin or bisphenol A-type resin and sandstone granular material, mainly in manufacturing the Glass Steel Tube process, in not moulding fully of Glass Steel Tube, add while thering is certain ductility and plasticity in other words sandstone particle composite bed is partially submerged into to the Glass Steel Tube outer surface, rear and Glass Steel Tube is one-body molded.Sandstone particle composite bed is selected silica sand, rubble (basalt or granite or limestone, cobble etc.), and its particle size range is 2.5-8mm.Particle layer adopts and wraps up in the outer surface that sandstone technique covers the frp lining pipe, can significantly strengthen the associativity of liner glass steel pipe and concrete layer by particle layer.The 2nd, between multiple tube, by inner lining glass fiber reinforced plastic birdsmouth form, connect, interface Glass Steel Tube outer wall is provided with two rubber sealing grooves, place rubber seal in groove, effectively strengthen pipe fitting rear whole sealing corrosion performance is installed, and can conveniently carry out the pipe coupling leakage test, should retain the interface pressurizing port in the middle of two cushion rubbers, whether the connection that checks birdsmouth seepage.
The beneficial effects of the utility model: multiple tube of the present utility model adopts wraps up in the combination that sandstone technique guarantees glass fibre reinforced plastics and reinforced concrete, realizes the good interface transition, has guaranteed the overall performance of composite pipe.From practice, this multiple tube one is that overall performance is good.Comprise resin layer, resin and sandstone particle layer composite bed, three kinds of form structure layers of reinforced concrete floor in reinforced concrete and composite glass steel pipe body, resin and reinforced concrete interface transition are good, in conjunction with firmly, the interface soundness that has solved traditional glass fibre reinforced plastics and reinforced concrete composite pipe is poor and shortcoming that integrity that cause is poor; Solved traditional reinforced concrete sewer pipe impervious poor, the body friction factor large and the flow velocity that causes slowly, the shortcoming of corrosion-resistant; Solved the poor shortcoming of simple glass steel supplying drainage bearing power.The 2nd, the pipe joint good seal.Adopt glass fibre reinforced plastics to make joint socket, engage well with the glass fibre reinforced plastics in body.Due to the moulding together with glass fibre reinforced plastics of birdsmouth joint, pipe joint and pipe shaft form one.The birdsmouth of the glass steel material by two rubber sealing forms is connected, easy for installation, the pipeline good integrity, and joint tighness is good.The 3rd, easy construction.Adopt the glass fibre reinforced plastics birdsmouth, having solved common glass fibre reinforced plastics and reinforced concrete composite pipe does not have the problems such as the joint sealing solved and the complexity of constructing, construction install convenience.The 4th, connector test is convenient.The birdsmouth of the glass steel material by two rubber sealing forms is connected, and can conveniently carry out connector test.
