Abstract
The utility model discloses a bell and spigot hot-dip galvanized lined prestressed steel cylinder concrete pipe, which comprises a cylinder part, and a bell steel ring and a spigot steel ring which are arranged at two ends of the cylinder part, wherein the cylinder part is sequentially provided with a steel cylinder inner wall concrete layer, a steel cylinder and a steel cylinder outer wall cement mortar protective layer from inside to outside; a prestressed steel wire is wound on the outer surface of each of the steel cylinder and the bell steel ring; and a hot-dip galvanized coating is arranged on the surface of each of the spigot steel ring and the bell steel ring. The concrete pipe is simple in structure and anticorrosive, and the service life of the prestressed steel cylinder concrete pipe can be effectively prolonged.
Description
Technical field
The utility model relates to a kind of prestressed concrete member, the bellmouth steel loop at especially a kind of Prestressed concrete cylinder pipe two ends and the lined Prestressed concrete cylinder pipe of socket steel ring heat dip zinc treating.
Background technique
At present, Prestressed concrete cylinder pipe (being called for short PCCP) is a kind of novel rigid pressure tubing.It is that the strong concrete tube core that has steel cylinder twines reinforcement wire; Spray is with cement mortar protective course; Adopt the steel bell and spigot steel loop and be welded into one with steel cylinder; Joint socket has the flexible joint that the groove O-ring seal has formed the sliding type cushion rubber, is the composite structure that steel plate, concrete, High Tensile Steel Wire and slush different materials are formed, and has steel and concrete characteristic separately.Prestressed concrete cylinder pipe have bear in external pressure high, joint tighness is good, shock resistance is strong, it is convenient and swift to execute, antiseptic property good, characteristic such as easy to maintenance; Paid close attention to by engineering circle, be mainly used in long distance water transfer main line, pressure inverted-siphon, town water supply engineering, the waterline of pressure, electric power plant circulating water engineering pipeline, pressure blowdown main etc. are arranged.Compare with tubing in the past, have applied widelyly, the economic life is long, anti-seismic performance good, easy for installation, advantage such as the operation expenditure is low, and is water-tight basically.Prestressed concrete cylinder pipe can be divided into two kinds from structural type: a kind of is lined Prestressed concrete cylinder pipe (PCCPL); Promptly at steel cylinder inwall moulding concrete; The direct winding ring orientation prestress steel wire in steel cylinder outside, gunite protective layer and the pipeline processed then; A kind of is embed-type Prestressed concrete cylinder pipe (PCCPE), is steel cylinder is embedded in tube core concrete the inside, then gunite protective layer after twining the ring orientation prestress steel wire on the tube core outer walls of concrete.
But as the concrete member product that is embedded in the edatope, in edatope, if Prestressed concrete cylinder pipe is not taked effective protective measure; Prolongation along with service time; Mortar cover and concrete layer in the corrosive medium intrusion Prestressed concrete cylinder pipe in the edatope of Prestressed concrete cylinder pipe outer wall and in the interior aqueous medium of pipe arrive steel wire and steel cylinder surface, and electrochemical corrosion will take place for steel wire and steel cylinder so; And then can cause the corrosion failure of steel wire and steel cylinder; Perforation taking place reveal even the booster phenomenon, causes a hidden trouble the operational reliability of direct threats pipe-line system can for the safe operation of pipe-line system; Wherein the etching problem of reinforcement wire and steel cylinder is the principal element that influences the structure durability; If steel wire and steel cylinder because of corrosion breakage take place, will directly cause the corrosion failure of Prestressed concrete cylinder pipe, thereby influence the safe operation of whole tubing.This shows and adopt anti-corrosion measure very necessary Prestressed concrete cylinder pipe; Wherein the joint socket steel loop of prestressed concrete pipe is directly exposed outside; There is not the protection of concrete layer; As the joint of two prestressed concrete pipes, the surface protection of the bellmouth steel loop of prestressed concrete pipe and the socket steel ring of prestressed concrete pipe is particularly important, the operational reliability of this direct threats pipe-line system; Thereby influence the safe operation of whole tubing, so the bellmouth steel loop at Prestressed concrete cylinder pipe two ends and socket steel ring process for treating surface are necessary extremely.
There is following shortcoming in present Prestressed concrete cylinder pipe technology:
The bellmouth steel loop and the socket steel ring surface at present domestic Prestressed concrete cylinder pipe two ends only are at the simple iron oxide red coating of external coating; Antiseptic effect is undesirable; Common iron oxide red coating can not effectively protect the bellmouth steel loop at Prestressed concrete cylinder pipe two ends and socket steel ring surperficial when corrosive medium corrodes bellmouth steel loop and the socket steel ring surface at Prestressed concrete cylinder pipe two ends; And then can cause corrosive medium to corrode the bellmouth steel loop and the socket steel ring surface at Prestressed concrete cylinder pipe two ends, bring hidden danger for the safe operation of pipeline.
Summary of the invention
The purpose of the utility model is for overcoming the bellmouth steel loop and the socket steel ring surface-treated technical deficiency at above-mentioned existing lined Prestressed concrete cylinder pipe two ends; A kind of lined Prestressed concrete cylinder pipe of joint socket heat dip zinc treating is provided; This concrete pipe is simple in structure; Corrosion-resistant, can effectively prolong working life of Prestressed concrete cylinder pipe.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of lined Prestressed concrete cylinder pipe of joint socket heat dip zinc treating; Comprise shell portion; And the bellmouth steel loop and the socket steel ring that are arranged at the shell portion two ends; Shell portion is followed successively by steel cylinder internal-wall concrete layer, steel cylinder and steel cylinder outer wall cement mortar protective course from inside to outside, all is wound with reinforcement wire on the outer surface of steel cylinder and bellmouth steel loop, is respectively equipped with the galvanizing coating on the surface of the surface of said socket steel ring and bellmouth steel loop.
Bellmouth steel loop and socket steel ring integral body are carried out heat dip zinc treating in the utility model, are welded on the steel cylinder two ends then respectively, and reinforcement wire is wrapped on the steel cylinder outer surface.
The utlity model has following beneficial effect:
1, the utility model makes the galvanizing coating through the method to bellmouth steel loop and the whole heat dip zinc treating of socket steel ring on joint socket steel loop inside and outside wall; For improving, the antiseptic property of lined Prestressed concrete cylinder pipe increased important barrier together, convenient in application.
2, the utility model overall structure is simple; Design science is reasonable; Have favorable durability, corrosion resistance; And manufacturing process is simple, and the lined Prestressed concrete cylinder pipe life-span of the whole heat dip zinc treating of process is effectively prolonged, and is the higher lined Prestressed concrete cylinder pipe of a kind of novelty.
