Abstract
The utility model discloses a reinforced concrete and glass reinforced plastic composite steel pipe, and aims to provide a reinforced concrete and glass reinforced plastic composite steel pipe with the advantages of corrosion resistance, high intensity, small flow resistance, reasonable manufacture and use costs, and convenient construction. The composite steel pipe comprises a circular steel pipe, and is characterized in that a glass reinforced plastic layer is arranged on the circumferential surface of the inner wall of the steel pipe; and a reinforced concrete layer is cast on the outer circumferential surface of the steel pipe. Connecting ports, which are mutually spliced, are arranged at two ends of the reinforced concrete and glass reinforced plastic composite steel pipe. After the composite steel pipes are mutually connected, the utility model allows a certain curvature, can be applied to the curvilinear construction, can 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 less than the steel amount used by a full steel pipe; the cost is low; the composite steel pipe can not be rusted; the service life is long; the welding process is not required during connection between the composite steel pipes; and the composite steel 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 glass fibre reinforced plastics composite steel tube 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, curve can not occur.Phenomenons such as that steel pipe is used of a specified duration yet can to occur is antirust, the preservative treatment pull-up falls, 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 glass fibre reinforced plastics composite steel tube of easy construction.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it includes circular steel pipe, it is characterized in that being provided with frp layer on the inwall circumferential surface of steel pipe, is cast with reinforced concrete floor on the outer peripheral surface of steel pipe.Be shaped on the connection mouth of mutual grafting at the two ends of reinforced concrete glass fibre reinforced plastics composite steel tube.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.
Reinforced concrete glass fibre reinforced plastics composite steel tube according to the such scheme manufacturing, because glass fibre reinforced plastics acid resistant alkali anti-corrosive properties are good, smooth surface, with its liner as steel pipe, make this pipe have good anti-corrosive properties, and smooth surface is not easy to adhere to dirt at tube wall, and the flow resistance of liquid in pipe is little; Cylindrical at steel pipe is cast with the good reinforced concrete floor of compression resistance, makes when the jacking operation of pipe, can bear huge propelling pressure.The seam crossing of pegging graft mutually at reinforced concrete glass fibre reinforced plastics composite steel tube 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 reinforced concrete glass fibre reinforced plastics composite steel tube uses are than lacking 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 glass fibre reinforced plastics composite steel tube.
Wherein: 1, steel pipe; 2, frp layer; 3, reinforced concrete floor; 4, steel bushing; 5, socket; 6, 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 glass fibre reinforced plastics composite steel tube.As seen from the figure, reinforced concrete glass fibre reinforced plastics composite steel tube includes circular steel pipe 1, is provided with frp layer 2 on the inwall circumferential surface of steel pipe 1, is cast with reinforced concrete floor 3 on the outer peripheral surface of steel pipe 1.Be shaped on the connection mouth of mutual grafting at the two ends of reinforced concrete glass fibre reinforced plastics composite steel tube.Described connection mouth is the overhanging steel bushing of an end 4, and the other end is shaped on the socket 5 that cooperates with steel bushing, is shaped on the annular groove 6 of placing seal ring on the excircle of socket 5.
