Reinforced concrete drainage pipe and manufacturing mold thereof

Abstract

The invention discloses a reinforced concrete drainage pipe and a manufacturing mold thereof, and belongs to the field of cement pipes. According to the reinforced concrete drainage pipe and the manufacturing mold thereof, the reinforced concrete drainage pipe comprises a drainage pipe body, and the drainage pipe body sequentially comprises a concrete layer, a reinforcing mesh, a concrete layer and an anti-corrosion and anti-permeability film from outside to inside. By adoption of the scheme, the anti-corrosion and anti-permeability film is additionally arranged on the inner surface of a cement pipe. Firstly, cracks with large gaps are prevented; and secondly, internal waterproof oil is used for filling the gaps, corrosive sewage is prevented from permeating into the cement pipe, a part of acid substances can be absorbed, corrosion resistance and impermeability of the cement pipe are effectively improved, the double-layer mold is adopted during manufacturing, the external mold can be immediately demolded, and the production process cannot be affected. The internal mold can play a role in maintenance, the outer surface can be kept wet in the natural maintenance process of the cement pipe, cracks are effectively avoided, the double-layer mold is combined and disassembled quickly and easily, operation is made convenient, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of cement pipes, in particular to a reinforced concrete drainage pipe and a manufacturing mold thereof. 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] The manufacturing process of cement pipe is centrifugal pipe making, hanging roller pipe making and mandrel vibration three kinds, among whic...

AI Technical Summary

Problems solved by technology

[0004] Although the cement pipe has many advantages, due to improper maintenance during production and the influence of various environmental factors, cracks are prone to appear on the inner surface, and the acid-corrosive sewage will penetrate into the interior of the cement pipe along the cracks during use. , causing irreversible damage to cement pipes, and currently only one mold is used for hanging roller pipes, and the mold cannot be demoulded immediately. The mold takes a long time, which is not conducive to mass production of cement pipes of the same specification
