Embodiment 1

[0023] A concrete pipe with steel fibers, its overall structure is composed of a pipe material 2 and a socket 4 and a socket 1 coaxially formed at its two ends respectively. The pipe is mixed with cement, water, sand and stones that meet the concrete strength ratio, and steel fiber 3 is added to continue stirring evenly. The length of the steel fiber is 15mm, the diameter is 0.3mm, and the cross section is circular. The steel fiber concrete that constitutes the pipe The components and their weights are respectively:

[0024] Cement 322Kg;

[0025] Water 140Kg;

[0026] Sand 475Kg;

[0027] Stone 864Kg;

[0028] Steel fiber 20Kg.

Embodiment 2

[0030] A concrete pipe with steel fibers. Steel fibers are added to the pipe concrete. The length of the steel fibers is 60 mm, the diameter is 1.2 mm, and the cross section is circular. The components and weights of the steel fiber concrete constituting the pipe are:

[0031] Cement 540Kg;

[0032] Water 220Kg;

[0033] Sand 828Kg;

[0034] Stone 1306Kg;

[0035] Steel fiber 140Kg.

[0036] Others are the same as in Example 1.

Embodiment 3

[0038] A concrete pipe with steel fibers, adding steel fibers in the concrete, the steel fibers have a length of 43mm, a diameter of 0.7mm, and a circular cross section, wherein the components and weights of the steel fiber concrete constituting the pipe are:

[0039] Cement 431Kg;

[0040] Water 180Kg;

[0041] Sand 650Kg;

[0042] Stone 1100Kg;

[0043] Steel fiber 80Kg.

[0044] Others are the same as in Example 1.

Abstract

The invention relates to a concrete pipe with steel fibers, which comprises the following components according to the parts by weight: 32-540 parts of cement, 140-220 parts of water, 475-828 parts of sand, 864-1,306 parts of pebbles and 20-140 parts of steel fibers. The concrete pipe has low raw material cost, light weight, high tensile strength, flexural strength, shearing strength and torsional strength, better durability and fatigue resistance, stronger capacities of shock resistance, abrasion resistance and cavitation resistance and better crack resistance, conforms to an energy saving and emission reduction policy and is a renewal product of the existing concrete pipes.

Description

technical field [0001] The invention belongs to the field of concrete pipes, in particular to a concrete pipe with steel fibers. Background technique [0002] The concrete pipes used in the field of water supply and drainage mainly include flat mouth, tongue and groove, socket and steel socket according to their interface types. According to the above-mentioned classification of large-diameter concrete drainage pipes, the pipe wall material is concrete, and the pipe wall is relatively thick, resulting in a large weight of the pipe itself, which is very difficult to hoist, transport and install, and the cost is high; Embedded with a steel skeleton composed of circumferential steel bars and longitudinal steel bars, the main function of the steel skeleton is to increase the overall stability of the concrete pipe to a certain extent, and improve the ability of the concrete pipe wall to resist external pressure loads and internal water pressure. Although the steel skeleton can i...
