Description
Technical field:
The utility model relates to a kind of building foundation engineering concrete special pile tube, belongs to concrete tubular pile and makes the field.
Background technology:
Notice of authorization CN2611433Y, title " pretensioning prestressed concrete abnormity pile tube ", this abnormity pile tube comprises the stake body that extends vertically, be provided with reinforcing rib in the stake body, be provided with the ring projection that radially becomes big at intervals on the stake body, the stake body between the ring projection is cylindrical.Its weak point: because the end of this abnormity pile tube is less than the diameter between its ring projection, therefore not only its loaded area is little, and bearing capacity is big; The 2nd, because the wall of special-shaped pile tube lacks vertical convex tendon, therefore resistance to compression, the flexural strength of whole pile tube are low, anti-shearing force is poor, make easily to cause pile tube to rupture by the waist in the follow-up construction of pile tube after piling and piling or phenomenon such as fracture; The 3rd, though the part of ring projection has increased the entire area of pile tube, but the increase deficiency of this area remedies the cost of production that ring lug boss branch produces, two difficulties that the carrying specification of pile tube are in whether go up, descend are wherein up leaned on (substituting large-diameter tubular pile), and then bearing capacity is not enough; Up do not lean on, though bearing capacity has surpassed the standard of its setting, waste one's talent on a petty job, make building costs increase considerably, the owner is reluctant to adopt.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, the one, be designed to the waveform pile body in the one or both ends of pile tube and the pile body of pile tube, purpose is the carrying Area of bearing that increases pile tube end face and pile body by wave structure, reaches the purpose that improves the pile tube pressure-bearing; The 2nd, the waveform pile body can make the pile tube internal stress after the shaping can be in the release that obtains between formed buffering fade zone between the waveform pile body progressively, avoid the crack that causes owing to internal stress in the pile tube forming process, guarantee the forming quality of waveform pile tube, and conveniently stripped.
Design scheme: in order to realize the application's above-mentioned purpose.The application is on the basis of existing special-shaped pile tube: 1, the pile body one or both ends are provided with the waveform convex tendon of projection, are one of features of the application.The purpose that the pile body one or both ends are provided with the wave convex tendon of projection is: because the size of the bearing capacity of pile tube depends on two parameters, one is the size of pile tube end face, one is the size of tubular pile body area, the bearing capacity of pile tube end face account for whole pile tube bearing capacity about 35%, the bearing capacity of tubular pile body area accounts for about 65% of whole pile tube.Therefore the application increases the area of pile tube end face, just equals to have increased the bearing capacity of pile tube, and this is an one, also is that background technology institute is unsolved.2, the convex tendon of tubular pile body wave-like design, be the application feature two.The purpose of wave-like convex tendon design is: because the friction that tubular pile body and underground produced is the support force of pile tube, in whole pile tube bearing capacity, tubular pile body accounts for about 65% of whole pile tube bearing capacity, and the application is provided with the wave convex tendon on the pile tube wall, not only can increase the effective area of tubular pile body significantly, and can improve the pile tube carrying significantly, the more important thing is the wave convex tendon on the tubular pile body and the formed prevention ring of waveform convex tendon of pipe pile end portion, can form prevention with soil and cooperate, improve the block support force of soil property significantly stake; Secondly, because when prestressed concrete pipe pile is shaped, the rod iron that is positioned at concrete tubular pile must be haled extension, and the prestressed concrete pipe pile that is positioned at concrete tubular pile shaping steel die cover is after making forming pile, there is huge internal stress in the pile tube inside that is positioned at shaping steel die, this internal stress acts directly on the pile tube, because wave convex tendon and the formed arcuate structure of tubular pile body can satisfy the required intensity of pile tube internal stress disappearance, guarantee in the process of pile tube internal stress disappearance, can not produce counter productive, fundamentally solve the pile tube problem of cracks that the pile tube internal stress is caused pile tube itself.3, on the pile tube wall between the waveform convex tendon vertically the convex tendon cross section go to the bottom and the pile tube face between the design of angle, be the application feature three.Pile tube face and the vertical convex tendon cross section angle purpose of design of going to the bottom is: because prestressed concrete pipe pile is when being shaped, the rod iron that is positioned at concrete tubular pile must be haled extension, and the prestressed concrete pipe pile that is positioned at concrete tubular pile shaping steel die cover is after making forming pile, there is huge internal stress in the pile tube inside that is positioned at shaping steel die, this internal stress acts directly on the pile tube, because vertically convex tendon is distributed on the pile body of pile tube along long, not only can satisfy the required intensity of pile tube internal stress disappearance, guarantee in the process of pile tube internal stress disappearance, can not produce counter productive, fundamentally solve the pile tube problem of cracks that the pile tube internal stress causes pile tube itself.
Technical scheme 1: the waveform pile tube, it comprises pile body (1), the outer wall of pile body (1) is the waveform convex tendon (2) of convex-concave.
Technical scheme 2: the waveform pile tube, it comprises pile body (1), the concave shaped portion that the outer wall of pile body (1) is the waveform muscle of the waveform convex tendon (2) of convex-concave and convex-concave is provided with vertical convex tendon (3).
The utility model is compared with background technology, the one, the design of the design of pile tube outer wall convex-concave waveform muscle and the concave portions of convex-concave waveform muscle vertical or 2 or many convex tendons, not only enlarge effective Area of bearing of whole pile tube effectively, and increased substantially the supporting capacity of pile tube, the bearing capacity of its φ 400mm pile tube is equivalent to the bearing capacity of φ 500mm pile tube, greatly reduces cost of production; The 2nd, be positioned at the convex-concave waveform muscle on the pile tube wall, satisfy the required intensity of pile tube internal stress disappearance, avoided of the damage of pile tube internal stress to pile tube, the pile tube quality after guaranteeing to be shaped, and can be conveniently stripped.
