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:

Abstract

This invention declares a gelled mortar dissected composite pipe with glass fiber reinforced plastic inner covering and outer protective layer. There is an alkali-stimulated inorganic gelled sand-doped layer between the mentioned glass fiber reinforced plastic inner covering and outer protective layer. This invention has a high tensile strength, compressive strength, bending strength and fracture elongation, also has high resistance to leakage and corruption.

Description

Technical field: [0001] The invention relates to a water supply and drainage pipe, in particular to a high-strength, low-cost alkali-activated inorganic gelled mortar sandwich composite pipe. Background technique: [0002] FRP sand-filled pipe, also known as glass fiber reinforced thermosetting resin sand-filled pipe, is composed of FRP inner lining layer, FRP inner structure layer, resin sand layer, FRP outer structure layer and FRP outer protective layer. In the engineering example, the positive pressure in the area near the center of the pipe wall under external pressure is very small, which is borne by the resin mortar layer with low tensile strength. Since the tensile strength of the resin sand layer is very low, the tensile strength is only 5-10Mpa, so when designing the pipeline, the designer only considers the tensile strength of the pure fiber resin layer, and the hoop tensile strength of the general fiber resin layer is 300Mpa, and the axial tensile strength is 15...
