Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Figure 1 to Figure 4 It schematically shows a special-shaped prestressed combined support pile steel form according to an embodiment of the present invention.
[0021] Such as Figure 1 to Figure 4 As shown, the special-shaped prestressed combined support pile steel mold of the present invention includes an oval first steel mold 1 and an oval second steel mold 2 .
[0022] Such as figure 1 and figure 2 As shown, the first steel mold 1 is provided with first arc-shaped plates 101 along the axial direction of the first steel mold 1 at both ends of its long axis, and the first arc-shaped plates 101 protrude toward the center of the first steel mold 1 .
[0023] A plurality of first support members 301 are welded at intervals on the side of the first arc-shaped plate 101 facing the inner wall of the first steel mold 1 , and...

The invention provides a special-shaped prestress combined support pile steel mold which comprises first elliptic steel molds and second elliptic steel molds. The first steel molds are arranged at the two ends of a long shaft. A first arc-shaped plate is arranged in the axial direction of each first steel mold. The positions, towards the central positions of the first steel molds, of the first arc-shaped plates protrude. The first arc-shaped plates and the first steel molds are detachably connected. The second steel molds are located at the two ends of the long shaft. A second arc-shaped plate which is consistent with the first arc-shaped plates in radian is arranged in the axial direction of each second steel mold. The positions, away from the central positions of the second steel molds, of the second arc-shaped plates protrude. The second arc-shaped plates and the second steel molds are detachably connected. Semi-circular plates are arranged in the axial direction of the middles of the two second arc-shaped plates of the second steel molds. The semi-circular plates are located on the arc-shaped inner sides of the second arc-shaped plates. The concave faces of the semi-circular plates are towards the second arc-shaped plates and are detachably connected with the second arc-shaped plates. The special-shaped prestress combined support pile steel mold is suitable for manufacturing special-shaped prestress combined support piles, and also suitable for manufacturing common tubular piles after disassembly, the use range is expanded, and the cost and materials are saved.
Description
technical field [0001] The invention relates to a mold for manufacturing pipe piles, in particular to a special-shaped prestressed combined support pile steel mold. 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 p...
