Embodiment 1
[0034] (1), the preparation of lining mould: on the concrete pipe core that has steel tube, wind the hoop prestressed steel wire, prepare into PCCP pipe semi-finished product, this PCCP pipe semi-finished product is directly used as lining mould, prefabricated in the concrete pipe core There is a reinforced net; the setting of the reinforced net is to improve the mechanical properties of the pipeline such as compression resistance and tensile strength, prevent cracks, and reduce the burden on the steel cylinder in the pipeline;
[0035] (2), external mold pretreatment: coat a layer of release agent on the inner wall of the external mold;
[0036](3) Construction of the pouring structure: from the inside to the outside, the lining mold, the reinforcement net, and the outer mold are sequentially composed of the pouring structure, and polymer concrete is poured into the pouring structure, and the outer mold is removed after molding to obtain polymer reinforced prestressed steel. ...
Embodiment 2
[0052] The difference from Example 1 is:
[0053] The polymer concrete includes 92% of aggregates, 8% of resin binders and auxiliary agents in total by mass percentage, and the aggregates include 1- 3 mesh quartz sand, 5-9 mesh quartz sand, 20-30 mesh quartz sand, 40-60 mesh quartz sand, 80-100 mesh quartz sand, 140-200 mesh quartz sand.
[0054] In terms of mass percentage, the auxiliary agent includes a curing agent accounting for 1.8% of the mass of the resin adhesive, an accelerator accounting for 0.4% of the mass of the resin adhesive, a coupling agent accounting for 2% of the mass of the resin adhesive, and an accounting for 2% of the mass of the resin adhesive. 0.03% of the polymerization inhibitor by mass of the mixture, and 5% of the flame retardant by the mass of the resin binder.
[0055] During the preparation of polymer concrete, the gelation time of step D is 3 minutes. When gelling, the ambient temperature is controlled at 20°C-21°C, and the humidity is 51%-53%...
Embodiment 3
[0057] The difference from Example 1 is:
[0058] The polymer concrete includes 93% of aggregates, 7% of resin binders and auxiliary agents in total by mass percentage, and the aggregates include 2- 3 mesh quartz sand, 6-8 mesh quartz sand, 15-25 mesh quartz sand, 35-55 mesh quartz sand, 90-110 mesh quartz sand, 150-180 mesh quartz sand.
[0059] In terms of mass percentage, the auxiliary agent includes a curing agent accounting for 1.4% of the mass of the resin adhesive, an accelerator accounting for 0.3% of the mass of the resin adhesive, a coupling agent accounting for 1.5% of the mass of the resin adhesive, and accounting for 1.5% of the mass of the resin adhesive. Mixture quality 0.025% polymerization inhibitor, accounting for 6% flame retardant resin binder quality.
[0060] During the preparation of the polymer concrete, the gelation time of step D is 4 minutes. During the gelation, the controlled environment temperature is 20° C.-22° C., and the humidity is 52%-54%. ...
