Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 and figure 2 It schematically shows a prestressed combined support pile steel form according to an embodiment of the present invention.

[0015] Such as figure 1 and 2 As shown, the prestressed combined support pile steel form of the present invention includes a cylindrical steel form body 1 .

[0016] The two symmetrical positions of the inner wall of the steel mold body 1 are respectively provided with an arc-shaped plate 2 along the axial direction of the steel mold body 1 and has an arc-shaped cross section. Both sides of the arc-shaped plate 2 are in close contact with the inner wall of the steel mold body 1 .

[0017] The inner arc surface of the arc plate 2 is welded with a plurality of support members 21 at intervals, and the support members 21 are provided with a first screw hole perpendicular to the arc...

Abstract

The invention provides a prestressed composite supporting pile steel mould which comprises a cylindrical steel mould body. The prestressed composite supporting pile steel mould is characterized in that curved plates provided with curved cross sections and arranged along the axial direction of the steel mould body are arranged on symmetrical positions on two sides of the inner wall of the steel mould body, curved surfaces of the curved plates protrude at a position facing to the center of the steel mould body, the two sides of the curved plates are in close contact with the inner wall of the steel mould body, and the curved plates are detachably connected with the steel mould body. The prestressed composite supporting pile steel mould is not only applicable to manufacturing of prestressed composite supporting piles but also applicable to manufacturing of ordinary tubular piles after being demounted, so that application range is enlarged, and materials and cost are saved.

Description

technical field [0001] The invention relates to a mold for manufacturing pipe piles, in particular to a steel mold for prestressed combined support piles. Background technique [0002] With the development of concrete technology, the technology of concrete pipe piles is becoming more and more mature. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. Pipe piles include prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles), prestressed high-strength concrete pipe piles (PH pipe piles), thin-walled steel pipe centrifugal concrete pipe piles (TSC pipe piles) ). [0003] However, in the field of engineering support, concrete pipe piles have not yet been involved. [0004] At present, slab bricks are used for engineering support, such as: river embankment support, wharf front support, coastal slope protection,...
