Embodiment 1

[0041] An electrothermally welded modified sulfur concrete pipe, such as Figure 1 ~ Figure 4 As shown, it includes several sections of pipe fittings inserted sequentially. One end of each section of pipe fitting is a tapered socket, and the other end is a tapered socket. There are multiple coils of electric heating wire 4 wound around the outer periphery, the electric heating wire is wound in a spiral manner, and an electrode joint for connecting to a power supply is provided. The electric heating wire heats up after being energized so that the inner and outer walls of the front and rear pipe fittings are thermally fused and fixed together. The outer wall of the tapered socket and the inner wall of the tapered socket are respectively wrapped with a steel plate lining ring to prevent the material from being softened and deformed by overheating.

[0042] The formula materials of the pipe fittings are (by mass parts): 15% of modified sulfur, 14% of cement micropowder, 51% of gr...

Embodiment 2

[0053] The structure of the pipe fittings in this example is the same as in the first embodiment.

[0054] The formula materials of the pipe fittings are (by mass parts): modified sulfur 17%, mineral powder 14%, granite coarse aggregate 50%, machine-made sand 19%;

[0055] Described modified sulfur formula material is (by mass): waste rubber powder 40%, sulfur 60%;

Abstract

The invention discloses an electric heating fusion connection type modified sulfur concrete pipe and a manufacturing method thereof. The electric heating fusion connection type modified sulfur concrete pipe comprises a plurality of pipe fitting segments which are sequentially connected in an inserted manner, wherein one end of each pipe fitting segment is a conical socket, the other end of each pipe fitting segment is a conical spigot, the conical socket of the front pipe fitting is connected with the conical spigot of the corresponding back pipe fitting in a sleeving manner, electric heatingmetal wires are wound around the outer periphery of the conical spigots, and after the electric heating metal wires are electrified, the electric heating metal wires emit heat to enable the front pipefitting and the corresponding back pipe fitting to be fixed together through hot fusion. The pipe fitting is made of the material of the following modified sulfur concrete formula with a heating andpouring formation method. The modified sulfur concrete formula comprises, by mass, 15%-24% of modified sulfur, 12%-21% of filler, 46%-55% of stone and 18%-27% of sand. The modified sulfur concrete pipe material achieves connection in an electric heating fusion manner; and compared with a common concrete pipe material, the modified sulfur concrete pipe material has the advantages that the connection manner is simple and reliable, seal performance is good, and the construction efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a pipe material for municipal engineering. Background technique [0002] In municipal engineering and construction engineering, pipe material is an indispensable material. According to the source of materials, commonly used construction pipe materials can be divided into metal, plastic and concrete pipe materials. The metal pipe body material is easily corroded during long-term use, rust and scale appear, water leakage and blockage occur, and it is easy to affect human health, which seriously restricts its application and development. The plastic pipe body material has the advantages of light weight, smooth pipe wall, high chemical inertness, long life, etc., and has been fully developed and applied at present. However, it also has defects such as poor mechanical properties, insufficient rigidity, flammability, and low temperature resistance. Compared with plastic pipe materials, concrete has the advantages of good quality, ...
