Abstract
The utility model relates to an anticorrosive abrasion resistant protective layer for external wall of straight-push steel pipe, which belongs to the field of the protective layer of the outer wall of the steel pipe for giving and exhausting water. The anticorrosive abrasion resistant protective layer for external wall of straight-push steel pipe mainly solves the problems that the frictional resistance of the abrasion resistant protective layer in the straight-push construction is high and the crevice and the fragmentation of the abrasion resistant protective layer are easy to happen. An abrasion resistant protective layer (2) which is composed of a resin protective layer (3) and a glass epoxy protective layer (4) are arranged outside an anticorrosive layer (1), and quartz sand (5) can be mixed in the resin protective layer (3); a diabase protective layer (6) is arranged between the anticorrosive layer (1) and the resin protective layer (3). The utility model has the benefit that the abrasion resistant protective layer (2) has light weight, hard material, good abrasion resistance, small frictional resistance, good anticorrosion performance, no conductivity, and better water resistance. The crevice and the fragmentation of the abrasion resistant protective layer (2) of the steel pipe in the straight-push construction under the ground can be completely avoided, and furthermore, the problem of the performance of the anticorrosive layer (1) can be influenced to ensure the permanent buried steel tube of water feed, in particular to the safety and the stability of the water supply steel pipe with big diameter. The normal production and the life of people can be guaranteed, and the utility model also has the advantages of convenient manufacture and convenient construction.
Description
Technical field
The utility model belongs to the protective layer field of plumbing outer wall of steel pipe, relates to a kind of straight top outer wall of steel pipe anticorrosion antiwear protective layer.
Background technique
In the prior art; bury the ground water supply steel tube in underground vertical top type construction; for prevent that outer wall is corroded and in the process of straight top its outer wall by the mill hurt; generally at first at outer wall of steel pipe coating one deck anticorrosive coat; anticorrosive coat is done one deck outward again and is made skeleton with steel ring and steel wire and have the certain thickness slush wear-resistant protective layer that has antisepsis concurrently; its deficiency exists; make caliber and weight increase bigger in thicker slush anticorrosive coat; cement mortar protective course surface friction drag in jack-in process is big; increase lifting; transportation; workload and work difficulty with construction; the slush wear-resistant protective layer crack or chipping occurs easily in the vertical top type construction; the antiseptic property of anticorrosive coat in having a strong impact on; thereby lose protective action, influence the working life of water conveyance steel tube steel pipe.
Summary of the invention
The technical problem that solves: for straight top outer wall of steel pipe provides a kind of new anticorrosion antiwear protective layer; overcome the deficiencies in the prior art; can avoid wear-resistant protective layer in the vertical top type construction, crack or chipping to occur, and antiseptic property is good, surface friction drag is little, wear-resisting property is good, in light weight, easy construction.
The technological scheme that adopts:
Straight top outer wall of steel pipe anticorrosion antiwear protective layer has anticorrosive coat 1 and wear-resistant protective layer 2, and it is characterized in that: wear-resistant protective layer 2 is by inside and outside two-layer the composition, and internal layer is a resin protective layer 3, and skin is the glass fibre reinforced plastics protective layer 4 of resin and glass dimension fibre or glass cloth composition.
Beneficial effect:
Wear-resistant protective layer 2 light weights of forming by resin protective layer 3 and glass fibre reinforced plastics protective layer 4 and hard; wear-resisting property is good; surface friction drag is little; antiseptic property is good; non-conductive; water-fast; especially outer field glass fibre reinforced plastics protective layer 4; its mechanical strength can be compared with steel; therefore can avoid steel pipe wear-resistant protective layer 2 in underground vertical top type construction crack or chipping to occur fully; and further influence the performance issue of anticorrosive coat 1; thereby can guarantee the nonvolatil ground water supply steel tube that buries; the particularly Security of the water supply steel tube that diameter is big; thereby help guaranteeing the Security of whole engineering, and manufacture and construct all more convenient.
Description of drawings
Fig. 1, structure are formed schematic representation;
Fig. 2. the structure that contains the resin protective layer 3 of resin and silica sand mixed construction is formed schematic representation;
Fig. 3, the structure with diabase protective layer 6 are formed schematic representation;
Embodiment
5 are shown silica sand, 7 and are shown steel pipe walls among the figure;
Shown in Fig. 1,2 and 3, glass fibre reinforced plastics protective layer 4 is glass fibre or glass cloth multi-lay winding formula structure.
As shown in Figure 2, resin protective layer 3 is resin and silica sand 5 mixed construction.
As shown in Figure 3, between anticorrosive coat 1 and resin protective layer 3, also has diabase protective layer 6.
Method for production is as follows:
Straight top steel pipe is contained on the fixed support, and to make steel pipe be that rotating shaft is rotated with its central axis;
At first on the outer wall of steel pipe walls 7, be coated with anticorrosive coat 1 in accordance with regulations;
Next is coated with in accordance with regulations in the outside of anticorrosive coat 1 again and contains the resin protective layer 3 of curing agent, if sneak into silica sand 5 in containing the resin of curing agent, can make the resin protective layer 3 with resin and silica sand 5 mixed construction.
At last, under steel pipe average rate rotation, with glass fibre or glass cloth insulating varnish in accordance with regulations multiple layer be wrapped in the outside of resin protective layer 3, promptly make glass fibre reinforced plastics protective layer 4; When also having diabase protective layer 6, need earlier anticorrosive coat 1 outside in accordance with regulations that coating resin and diabase mix the diabase protective layer 6 of composition, and then manufacture resin protective layer 3, manufacture glass fibre reinforced plastics protective layer 4 at last again.
Raw materials used:
Diabase is preferably selected diabase flour for use;
Resin is selected unsaturated polyester resin for use;
Curing agent is selected peroxide firming agent for use.
Claims (3)
1, straight top outer wall of steel pipe anticorrosion antiwear protective layer; have anticorrosive coat (1) and wear-resistant protective layer (2); it is characterized in that: wear-resistant protective layer (2) is by inside and outside two-layer the composition, and internal layer is resin protective layer (3), and skin is the glass fibre reinforced plastics protective layer (4) of resin and glass dimension fibre or glass cloth composition.
