Abstract
The utility model discloses a reinforced concrete and glass reinforced plastic composite pipe, and aims to provide a reinforced concrete and glass reinforced plastic composite pipe with the advantages of corrosion resistance, high intensity, small flow resistance, reasonable manufacture and use costs, and convenient construction. The composite pipe adopts a segment of circular pipe; a glass reinforced plastic layer is arranged on the inner wall of the pipe; a steel mesh is wrapped on the outer circumference of the glass reinforced plastic layer; a resin-impregnated glass fiber layer is wound outside the steel mesh; and a reinforced concrete layer is cast on the outer circumferential surface of the glass fiber layer. After the composite pipes are mutually connected, the utility model allows a certain curvature, can be applied to the curvilinear construction to steer clear of obstacles, and particularly thoroughly solves the problem of pollution of the electromagnetic field generated by the steel pipes connected by applying long lines. The steel amount used by the reinforced concrete and glass reinforced plastic composite steel pipe is far less than the steel amount used by a full steel pipe; the cost is low; the composite pipe can not be rusted; the service life is long; the welding process is not required during connection between the composite pipes; and the composite pipe relates to an underground jacking high internal pressure liquid transport pipe with high intensity, low cost, safety and sanitation, and convenient construction.
Description
Technical field
The utility model relates to the conveyance conduit that is used for high pressure liquid, particularly a kind ofly is embedded in the underground reinforced concrete composite glass steel pipe that is used for supply and drain water system.
Background technique
For at the provided underground water supply and sewerage pipeline, minimizing is to the destruction of ground installation, modern form of construction work is with push-bench one section one section conduit pipe to be formed at underground jacking paving forward, though this form of construction work is not destroyed the face of land, but the requirement of strength to the conduit pipe that is used for jacking is very high, also require to bear high interior the pressure when having, to satisfy the usefulness of high pressure water delivery, normally with the bigger steel pipe of wall thickness, but in order to prevent that steel pipe from getting rusty, it is antirust to carry out multilayer at the inner and outer surface of steel pipe, preservative treatment, this is the user cost height not only, needs welding between each section steel pipe, time-consuming taking a lot of work, technical requirements height to construction, cycle is long, and in case underground sedimentation occurs, dislocation is easy at the seam crossing of pipeline cracking and seepage take place, and this pipeline that connects with steel can cause interference to being embedded in underground electromagnetic signal facility, as the communication of subway, underground communication optical cable etc.In addition, the laying direction of pipeline also must be a straight line, can not carry out the curve construction.Phenomenons such as steel pipe is used of a specified duration anticorrosive coat yet can to occur and come off, and the corrosion polluted water takes place, and working life is short.Though have glass fibre reinforced plastics concrete composite pipe or resin concrete can not get rusty on the market, their high-voltage resistance capability is low, can not be used for the application in high interior pressure pipe road.
The model utility content
The purpose of this utility model provide a kind of have corrosion-resistant, intensity is high, flow resistance is little, manufacturing cost and use cost rationally, the reinforced concrete composite glass steel pipe of easy construction.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it is the pipe of one section circle, it is characterized in that tube inner wall is a frp layer, on the excircle of frp layer, be enclosed with steel wire, be wound with the glass fibre layer of insulating varnish in the outside of steel wire, on the outer peripheral surface of glass fibre layer, be cast with reinforced concrete floor.Be shaped on the connection mouth of mutual grafting at the two ends of reinforced concrete composite glass steel pipe.Described connection mouth is the overhanging steel bushing of an end, and the other end is shaped on the socket that cooperates with steel bushing, is shaped on the annular groove of placing seal ring on the excircle of socket.
According to the reinforced concrete composite glass steel pipe of such scheme manufacturing, because glass fibre reinforced plastics acid resistant alkali anti-corrosive properties are good, smooth surface, with it as liner, make this pipe have good anti-corrosive properties, and smooth surface is not easy to adhere to dirt at tube wall, the flow resistance of liquid in pipe is little; Middle steel wire has increased mutual combination force and has born high interior pressure with the glass fibre layer that is wound with insulating varnish, is cast with the good reinforced concrete floor of compression resistance at cylindrical again, makes when the jacking operation of pipe, can bear huge propelling pressure.The seam crossing of pegging graft mutually at the reinforced concrete composite glass steel pipe can seal with seal ring, allow certain camber after interconnecting, can do the construction of curve, thereby can get around some obstacles, especially thoroughly solve and used the electromagnetic field pollution problem that long line connects steel tube place's generation.The steel that the reinforced concrete composite glass steel pipe uses are more than few with all steel pipe, cost is low, can not produce corrosion, long service life, mutual connection need not be welded, and is pressure infuser pipe in the buried jacking height of a kind of intensity height, cheap, safety and sanitary, easy construction.
Description of drawings
Fig. 1 is the structural representation of reinforced concrete composite glass steel pipe.
Wherein: 1, frp layer; 2, steel wire; 3, glass fibre layer; 4, reinforced concrete floor; 5, steel bushing; 6, socket; 7, annular groove.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of reinforced concrete composite glass steel pipe.As seen from the figure, it is the pipe of one section circle, and tube inner wall is a frp layer 1, is enclosed with steel wire 2 on the excircle of frp layer 1, be wound with the glass fibre layer 3 of insulating varnish in the outside of steel wire 2, on the outer peripheral surface of glass fibre layer 3, be cast with reinforced concrete floor 4.Be shaped on the connection mouth of mutual grafting at the two ends of reinforced concrete composite glass steel pipe.Described connection mouth is the overhanging steel bushing of an end 5, and the other end is shaped on the socket 6 that cooperates with steel bushing 5, is shaped on the annular groove 7 of placing seal ring on the excircle of socket 6.
