Description
Technical field
The present invention relates to be used for the conveyance conduit of liquid, particularly a kind ofly be embedded in underground reinforced bar glass fiber resin concrete pipe and the production method thereof 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 laid in underground jacking 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, normally use steel pipe, but in order to prevent that steel pipe from getting rusty, must carry out antirust processing at the inner and outer surface of steel pipe, as painting etc., and the user cost height of steel pipe, need welding between each section steel pipe, construction trouble, the cycle is long, and laying direction that also must pipeline is a straight line.Steel pipe has been used of a specified duration yet can the corrosion polluted water.Though have glass fibre reinforced plastics concrete composite pipe or resin concrete can not get rusty, their intensity is low, can not be used for the jacking operation of pipeline.
Summary of the invention
The purpose of this invention is to provide a kind of have corrosion-resistant, intensity is high, flow resistance is little, manufacturing cost and use cost is low, manufacturing process is simple, the reinforced bar glass fiber resin concrete pipe of easy construction and production method thereof.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it comprises the pipe that the concrete casting formed with unsaturated resin and silica sand forms, be shaped on the connection mouth of mutual grafting at the two ends of pipe, it is characterized in that in the peripheral wall of pipe, being provided with the reinforcing mesh of pipe shape, contain glass fibre in the concrete.
The production method of above-mentioned reinforced bar glass fiber resin concrete pipe, its feature is successively:
(1), reinforcing mesh makes: according to the size of reinforced bar glass fiber resin concrete pipe, be cast in the reinforcing mesh that becomes the pipe shape in the tube wall of reinforced bar glass fiber resin concrete pipe with reinforcement fabrication, an end of reinforcing mesh is connected with connection mouth;
(2), dress mould: the reinforcing mesh of pipe shape is put into the mould of forming tubulose by internal mold and external mold;
(3), batching: prepare burden by weight percentage: glass fibre 3%～8%, unsaturated resin 10%～25%, promoter 0.5%～1.5%, epoxy curing agent 1%～3% and silica sand 70%～85%;
(4), spice: according to above-mentioned prescription unsaturated resin, epoxy curing agent and promoter are stirred into the mixed with resin body together, adding silica sand and glass fibre continue to stir in the mixed with resin body, become concrete;
(5), cast: concrete is joined in the mould that reinforcing mesh is housed, and on one side and to add concrete closely knit with vibratory concrete with shaking machine, the air in the eliminating concrete makes concrete fully contact with mould inner wall with reinforcing mesh;
(6), solidify: static wait 2-3 hour allows unsaturated resin solidify hardening;
(7), the demoulding: remove internal mold and external mold, deviate from reinforced bar glass fiber resin concrete pipe;
(8), revise, check warehouse-in: repair surface imperfection, removal overlap, the burr of reinforced bar glass fiber resin concrete pipe, check is stamped certificate of conformity to the reinforced bar glass fiber resin concrete pipe that is up to the standards, and puts in storage.
Reinforced bar glass fiber resin concrete pipe according to the such scheme manufacturing, it substitutes common cement with resin and makes concrete pipe, reinforcing mesh and glass fibre in resin concrete, have been added again, play the effect of mutual tractive, its intensity is much higher than resin concrete or portland cement concrete pipe, weight is also light than same specification portland cement concrete pipe, and smooth surface is not easy to adhere to dirt at tube wall, liquid is little in interior flow resistance, seam crossing at each root reinforced bar glass fiber resin concrete pipe can seal with seal ring, certain camber can be allowed after interconnecting, thereby some buildings can be got around.Reinforced bar glass fiber resin concrete pipe has lower than steel pipe cost, can not produce corrosion, working life is longer than steel pipe, and mutual connection need not be welded, and is the buried jacking indusion tube that a kind of intensity height, cheap, safety and sanitary, easy construction can be widely used in water drinking tube or waste pipe etc.
