Conveying pipe sleeve for pumping concrete construction
The invention relates to a conveying pipe sleeve for a pumping concrete construction. The conveying pipe sleeve is in cup joint at the outer side of a conveying pipe (1), and is spliced by multiple sections of pipe sleeve units in a length direction of the conveying pipe; each section of the pipe sleeve unit is spliced by more than two pipe piece units; the pipe piece units are sealed cavities consisting of outer walls (4), inner walls (5), upper bottom surfaces, lower bottom surfaces and two side sealing plates (10); phase change materials (6) are filled in the sealed cavities; electric heating devices (7) are arranged at the inner sides of the inner walls, and temperature sensors connected with temperature control devices of the electric heating devices are embedded at the outer sides; and the inner sides of the outer walls are provided with reflective film layers (8) and heat insulating layers (9) in sequence from top to bottom. The multiple pipe piece units are clamped and fastened on the outer surface of the conveying pipe through connecting parts (11); the multiple sections of the pipe sleeve units are longitudinally spliced; and the upper and lower bottom surfaces of the adjacent pipe piece units are respectively provided with concave parts (12) and convex parts (13) with matched shapes. The pipe sleeve is simple in structure and convenient to be disassembled, prevents the blockage caused by low temperature, and improves the energy utilization rate.
