Problems solved by technology

However, the bulk density of concrete is relatively large, generally 2400kg / m3, resulting in heavy concrete pipe weight, which brings difficulties to transportation and installation
In addition, ordinary concrete is a brittle material with very low tensile strength, generally 5% of the compressive strength, so cracks are a common problem, and ordinary concrete has low impermeability and frost resistance.

Embodiment

[0037] see Figure 1 to Figure 4 As shown, the water delivery pipeline provided in this embodiment includes a pipe body 3 , a filling part 4 , a multi-layer reinforcement layer assembly, a socket piece 6 and a socket piece 7 .

[0038] Hereinafter, the above-mentioned components of the water delivery pipeline will be described in detail.

[0039] In the optional solution of this embodiment, the material of the pipe body 3 includes UHPC, and UHPC is ultra-high performance concrete. Under the premise of not changing the size and specifications of the pipe, the pipe body 3 can meet the basic mechanical performance requirements. There is still a margin of mechanical properties.

[0040] In this embodiment, sockets 6 and sockets 7 are provided at both ends of the pipe body 3 in the axial direction, so as to connect a plurality of water delivery pipes sequentially through the sockets 6 and sockets 7 .

[0041] Along the axial direction of the pipe body 3, the two ends of the filli...

Abstract

The invention relates to the technical field of water conveying concrete pipelines, in particular to a water conveying pipeline. The water conveying pipeline comprises a pipe body and a filling part; the pipe body is made of a material; and a filling part is prefabricated in the pipe body, and the filling part is made of a high-molecular polymer. According to the water conveying pipeline, a UHPC forming pipe body is adopted, the water conveying pipeline has obviously excellent crack resistance, freezing resistance, impermeability and durability, the durability life is prolonged to 100 years or above from 50 years, under the condition that the mechanical property is met, the UHPC material cost is effectively saved through the filling part, the self weight is effectively reduced, and therefore great convenience is brought to pipeline transportation and installation.

Description

technical field [0001] The invention relates to the technical field of water delivery concrete pipelines, in particular to a water delivery pipeline. Background technique [0002] Concrete is the most widely used material in the construction and cement products industries, and it is also the main material for making concrete pipes. However, the bulk density of concrete is relatively large, generally 2400kg / cubic meter, resulting in heavy concrete pipe weight, which brings difficulties to transportation and installation. In addition, ordinary concrete is a brittle material with very low tensile strength, generally 5% of the compressive strength, so cracks are a common problem, and ordinary concrete has low impermeability and frost resistance. [0003] These properties determine that the durability and safety of ordinary concrete pipes and their products are affected, so that the design reference life of concrete transportation and drainage pipes in my country is generally on...
