Embodiment 1
[0020] The structure of Example 1 is shown in Figure 1, an alkali-activated inorganic gelled mortar interlayer composite pipe has a glass fiber reinforced plastic inner liner 1, a glass fiber reinforced plastic outer protective layer 2, the glass fiber reinforced plastic inner liner 1 and the glass fiber reinforced plastic outer protective layer 2 There is an alkali-activated inorganic gelled sand layer 3 between them, and the production process is basically the same as that of the prior art, that is, it is produced according to the following procedures:
[0021] Making FRP inner lining layer 1——Curing FRP inner lining layer 1——Making alkali-activated inorganic gelled sand layer 3——Alkali-activated inorganic gelled sand layer 3 Curing——Making FRP outer protective layer 2——FRP outer layer The protective layer 2 is cured——making the socket——pipeline demoulding——inspection and storage.
[0022] Concrete method of operation is completely the same as prior art:
[0023] 1. Make th...
Embodiment 2
[0044] The structure of embodiment 2 is as shown in Figure 2, has glass fiber reinforced plastic lining layer 1, has fiberglass steel structure layer 4 outside the glass fiber reinforced plastic lining layer 1, and the outside of glass fiber reinforced plastic structure layer 4 has alkali-activated inorganic gelled sand layer 3, and alkali excitation The outside of the inorganic gelled sand layer 3 has a glass fiber reinforced plastic outer protective layer 2 .
[0045] Technology is substantially the same as embodiment 1, and production procedure is completely identical with prior art, promptly makes by following procedure:
[0046] Making FRP lining layer 1——Curing FRP lining layer 1——Making FRP structural layer 4——FRP structural layer 4 Curing——Making alkali-activated inorganic gelled sand layer 3——Alkali-activated inorganic gelled sand layer 3 Curing - making the outer protective layer of FRP 2 - outer protective layer of FRP 2 Curing - making the socket - demoulding the p...
Embodiment 3
[0049] The structure of Example 3 is shown in Figure 3: the others are the same as in Example 2, except that a glass fiber reinforced plastic structure layer 4 is made between the alkali-activated inorganic gelled sand layer 3 and the glass fiber reinforced plastic outer protective layer 2.
