Abstract

The invention discloses a method for manufacturing a well casing. The method comprises that: a concrete mixture is evenly put into or poured into a rotary well casing mould through openings at two ends of the well casing mould; and an iron roll is put into a port of the rotary well casing mould to roll the concrete mixture in the well casing mould repeatedly, and the concrete mixture is compacted. The method for manufacturing the well casing has the advantages of simple operation, high concrete strength, little damage to a body of the well casing, and high integrated intensity of the manufactured well casing.

Description

technical field

[0001] The invention belongs to the technical field of well pipes, in particular to a method for making well pipes. Background technique

[0002] The forming process of the well pipe is mainly produced by the centrifugal method, and a small amount is produced by the suspension roller method. Centrifugal method is divided into double-opening centrifugal steaming method and whole-mold spraying wax centrifugal molding method. The double-opening centrifugal method is made of two halves. The mold has been in production for a long time, and the wear is serious. The joints are prone to grout leakage. The centrifugation time is long, and the separation of stones, sand, and cement grout is easy to occur. The inner wall has serious laitance and the concrete strength is low. Whole mold wax spraying centrifugal molding method is conducive to mechanization of production, but the outer diameter is not easy to control, and the operation technology requirements are relative...
