The utility model discloses beneficial effect is: be fit for the construction of vacuum mud jacking post stretching prestressed concrete, guarantee prestressed duct filling compactness and plumpness, the anti -destructive is strong, increase with concrete area of contact, be favorable to the reliability of prestress wire grout back and the transmission of concrete member power, be used for pre -buriedly at the less component of thickness.
Description
Technical field
The utility model relates to plastic pipe, particularly be a kind of Bamboo-shaped prestressed flat mouth plastic pipe.
Background technology
In recent years along with the development of building trade, prestressed concrete is promoted gradually, and compared with conventional steel bar concrete, it is high that prestressed concrete has intensity, save the advantages such as material, now advanced technology is vacuum grouting post stressed concrete technology.Its feature is first concreting, pre-plugged helical metal pipe or plastic pipe in concrete, after concrete reaches some strength, tractive prestress wire in pre-buried helical metal pipe or plastic pipe again, then with ground tackle, prestress wire is fixed on component, finally vacuumizes at pipeline one end vacuum pump, make it produce the vacuum of-0.1Mpa, with grout pump, special cement is poured into from the pipeline other end again, until be full of pipeline.These spiral metal tubes or plastic pipe not only need for prestress wire provides protective barrier, also need higher sealing to ensure the quality of vacuum grouting.
Built-in pipe now for prestressed reinforced concrete construction is commonly helical form flat mouth metal tube or flat mouth plastic pipe, the flat mouth metal tube of this helical form or plastic pipe limit due to processing technology, can not the higher material of working strength or larger wall thickness, so in construction, be easy to be smashed to pieces by vibrating head or step on split.And due to helical form flat mouth metal tube outer rim having continuous print helical form muscle always, so more loaded down with trivial details in the encapsulation process of flat mouth pipeline junction, be easy to the phenomenon leaked air, reduce compactness and the plumpness of prestressed pore passage grouting.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of intensity is high, a kind of Bamboo-shaped prestressed flat mouth plastic pipe of good airproof performance.
The technical scheme solved the problems of the technologies described above is: a kind of Bamboo-shaped prestressed flat mouth plastic pipe, described Bamboo-shaped prestressed flat mouth plastic pipe is connected and composed successively by multiple tube couplings that structure is identical, and described each tube coupling includes: one that connects successively large flat mouth pipe, little flat mouth pipe, flat mouth pipe and a little flat mouth pipe in one; Described large flat mouth pipe cross section, in the shape of flat mouth pipe cross section and little flat mouth pipe cross section be: the left and right sides is the straight pipe wall be parallel to each other, and connects semicircle tube wall respectively at the two ends of two straight pipe walls, and straight pipe wall is identical with semi-circular tube wall thickness; Described large flat mouth pipe cross section, in the overall size of flat mouth pipe cross section and little flat mouth pipe cross section successively decrease successively.
Preferred version is: a described large flat mouth pipe, little flat mouth pipe, excessively connect with circular arc between flat mouth pipe and a little flat mouth pipe in one.
Preferred version is: the axial width of described large flat mouth pipe, in the axial width of flat mouth pipe and the axial width of little flat mouth pipe successively decrease successively.
Preferred version is: the two ends of described Bamboo-shaped prestressed flat mouth plastic pipe is little flat mouth pipe, and the width of the little flat mouth pipe of two ends is slightly longer than the width of the little flat mouth pipe in described tube coupling.
The beneficial effects of the utility model are:
1, the utility model adopts Bamboo-shaped flat mouth plastic pipe to replace the flat mouth pipeline of traditional helical form, seals easier, reliable.Be applicable to advanced vacuum grouting post stressed concrete construction, ensure compactness and the plumpness of prestressed pore passage grouting.
2, the utility model can the high material of selection intensity, and can make the prestressed plastic pipe of different wall specification, and use safer, anti-destructive is stronger.
3, the utility model adopt large flat mouth pipe and in the structure that replaces successively of flat mouth pipe, add the contact area of prestressed flat mouth plastic pipe and concrete component, laminating is stronger, is conducive to the reliability that prestress wire in prestressed flat mouth plastic pipe is in the milk afterwards and concrete component power is transmitted.
4, the utility model is flat mouth-shaped pipeline, can be used for being embedded in the less component of required thickness, and the scope of application is wider.

Detailed description of the invention
The utility model discloses a kind of Bamboo-shaped prestressed flat mouth plastic pipe, described Bamboo-shaped prestressed flat mouth plastic pipe 4 is connected and composed successively by multiple tube couplings 5 that structure is identical, and described each tube coupling 5 includes: flat mouth pipe 1 and a little flat mouth pipe 3 in one that connects the successively little flat mouth pipe 3, of large flat mouth pipe 2; Described large flat mouth pipe 2 cross section, in the shape of flat mouth pipe 1 cross section and little flat mouth pipe 3 cross section be: the left and right sides is the straight pipe wall be parallel to each other, and connects semicircle tube wall respectively at the two ends of two straight pipe walls, and straight pipe wall is identical with semi-circular tube wall thickness; Described large flat mouth pipe 2 cross section, in the overall size of flat mouth pipe 1 cross section and little flat mouth pipe 3 cross section successively decrease successively.
Excessively connect with circular arc between flat mouth pipe 1 and a little flat mouth pipe 3 in a described little flat mouth pipe 3, of large flat mouth pipe 2.
The axial width of described large flat mouth pipe 2, in the axial width of flat mouth pipe 1 and the axial width of little flat mouth pipe 3 successively decrease successively.
The two ends of described Bamboo-shaped prestressed flat mouth plastic pipe 4 is little flat mouth pipe 3, and the width of the little flat mouth pipe 3 of two ends is slightly longer than the width of the little flat mouth pipe 3 in described tube coupling 5.
In particular, Bamboo-shaped prestressed flat mouth plastic pipe 4 is integrated by mould compression molding, and wall thickness is everywhere equal, and can make the Bamboo-shaped prestressed flat mouth plastic pipe of different-thickness according to requirement of strength.Its material can be high-strength polyvinyl chloride, or other highstrenghtpiston.
Because the large flat mouth pipe 2 of Bamboo-shaped prestressed flat mouth plastic pipe 4 is separate, when doing encapsulation process, only need to utilize an other flat mouth pipe joint member, large flat mouth pipe 2 on adjacent Bamboo-shaped prestressed flat mouth plastic pipe 4 is sealed respectively, two Bamboo-shaped prestressed flat mouth plastic pipes 4 can be linked into an integrated entity.
In use, first concreting, in concrete, pre-plugged Bamboo-shaped prestressed flat mouth plastic pipe 4, utilizes flat mouth union or sweat soldering, adjacent two Bamboo-shaped prestressed flat mouth plastic pipes 4 is fixedly connected to form one.And then carry out follow-up implementing dragline operation to the prestress wire in Bamboo-shaped prestressed flat mouth plastic pipe 4.
