Honeycombed cement pipe and manufacturing process thereof

Abstract

The invention discloses a honeycombed cement pipe and a manufacturing process thereof, and belongs to the technical field of the honeycombed cement pipe. The honeycombed cement pipe comprises a honeycombed cement pipe, wherein a plurality of through holes which are uniformly distributed are formed in the honeycombed cement pipe and are penetrated up and down; the interior of the honeycombed cementpipe is fixedly connected to a plurality of steel bars which are evenly distributed; the diameters of the steel bars are 4-8mm; the material of the honeycombed cement pipe is concrete; the strength grade of the concrete is C30; the raw materials of the concrete comprise water, cement, sand, stone and concrete additives; the cement surplus coefficient of the concrete is 1.00; the maximum particlesize of the coarse aggregate is 20mm, collapsbillity is 35-50 mm, and sand rate is 28-30%; and by reasonably adding multiple pores in the production process of the cement pipe, the strength of the cement pipe is greatly enhanced, the usage amount of the cement material is greatly reduced, the solidification time is greatly reduced, the production efficiency is improved, and the weight of the cement pipe is reduced, and the transportation cost can be substantially reduced.

Description

technical field [0001] The invention relates to the technical field of porous cement pipe making, and more specifically relates to a porous cement pipe making process and its manufacturing process. Background technique [0002] Cement pipe is a kind of prefabricated pipe made of cement and steel bar, using the principle of centrifugal force of utility pole. Cement pipes, also known as cement pressure pipes and reinforced concrete pipes, can be used as sewer pipes in urban construction, sewage, flood control and drainage, as well as water pipes and farm wells used in some special factories and mines. Generally divided into: flat mouth reinforced concrete cement pipe, flexible tongue and groove reinforced concrete pipe, socket socket reinforced concrete pipe, F-shaped steel socket cement pipe, flat collar interface cement pipe, tongue and groove cement pipe, etc. [0003] There are three processes for making cement pipes: centrifugal pipe making, suspension roller pipe making...

AI Technical Summary

Problems solved by technology

[0004] The walls of small and medium-sized cement pipes in the prior art are generally solid cores without holes in the middle. Due to the characteristics of cement after solidification, the stress between them is too large, and the stress between these materials cannot be dispersed by the cement pipe itself. Or eliminate it, this structure can not withstand strong external force, and in many cases it will be broken, and a lot of cement materials are wasted, which leads to an increase in cost, but it cannot improve the cement pipe. Intensity, a lot of manpower and material resources are wasted, and it takes a long time to solidify, which affects production efficiency
