Abstract
The invention relates to a tensioned spun concrete (TSC) and prestressed high-strength concrete (PHC) combined pile which comprises a PHC tubular pile and a TSC tubular pile; the innovation points are as follows: the combined pile comprises at least one PHC tubular pile and at least one TSC tubular pile, wherein the TSC tubular pile is arranged at an upper part, and the PHC tubular pipe is arranged at a lower part; the tubular piles are arranged concentrically; and all the tubular piles are fixedly connected by welding or by quick connectors. According to the TSC and PHC combined pile, the PHC tubular pile and the TSC tubular pile are integrated and are fixedly connected by welding or by the mechanical connection of quick connectors. The TSC and PHC combined pile not only has the advantages of a pure steel tubular pile but also has good driving resistance, a pile formation process is consistent with that of the pure steel tubular pile, and the cost is saved by about 40 percent when the length is the same; and after being combined, the TSC tubular pile is mainly used for structural horizontal force resistance, the specific length of the TSC tubular pile is determined according to the actual engineering horizontal force resistant requirement, can replace the traditional pure steel tubular pile, so that the price is reduced on the premise that engineering requirements are met, and the resources are effectively saved.
Description
Technical field
The present invention relates to a kind of pile tube, particularly a kind of cost is low and meet TSC, the PHC compound pile of engineering demand.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except being applied to industry, civilian construction, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.Pile tube comprises prestressed concrete pipe pile (PC pile tube), thin tubular piles produced by prestressed concrete (PTC pile tube), prestressed high-strength concrete pile (PHC pile tube), centrifugal tubular pile with concrete of thin-wall steel pipe (TSC pile tube).
The PS steel pipe pile also is a kind of pile foundation material that develops rapidly in recent years, be mainly used on highrise building and large bridge and the large equipment base, along with building up of Construction of Hangzhou Bay Cross-sea Bridge, steel pipe pile is anti-corrosion measure and construction technology maturation in seawater, and increasing application will be arranged from now on.Steel pipe pile anti-bending strength and shear behavior are fine, easy construction, and the durable resistance energy is excellent pile foundation material, and the problem of unique existence is exactly that steel quantity consumption is large, and the financial cost index is high.
Summary of the invention
It is low and meet TSC, the PHC compound pile of engineering demand that the technical problem to be solved in the present invention provides a kind of cost.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of TSC, PHC compound pile, and its innovative point is: comprise PHC pile tube and TSC pile tube, all at least one of described PHC pile tube and TSC pile tube, described PHC pile tube and TSC pile tube arrange with one heart; Be connected and fixed by welding or fast connecting joint between PHC pile tube and the TSC pile tube.
Further, described TSC pile tube is on top, and the PHC pile tube is in the bottom.
Further, described TSC pile tube can be combined by the TSC pile tube segmentation of different thickness of steel pipe.
Further, described PHC pile tube, TSC pile tube are connected and fixed by inside and outside groove built-up welding between the end plate.
Further, described fast connecting joint comprises a pair of mounting flange, this is welded on respectively the pile end board place that needs connection to mounting flange, and the outer end of mounting flange arranges annular lip, and the mounting flange external surface of annular lip inboard is distributed with some radial screw bore; Several circular arc anchor ear plates, the inner arc center of described anchor ear plate have the location embeded slot that arranges along the circular arc bearing of trend, and the arc convex outer arc surface that embeded slot both sides, location form has the through hole corresponding with two mounting flange radial screw bore; The location embeded slot of anchor ear plate just can hold the mounting flange annular lip of being close to docking in two outer faces and embed, and the anchor ear plate is connected and fixed with two mounting flanges respectively by bolt.
The invention has the advantages that: TSC, PHC compound pile adopt PHC pile tube and TSC pile tube to combine, and utilize the mode of welding or fast connecting joint mechanical connection to be connected and fixed.The advantage that had both had the clean steel pile tube, durable resistance is good, and pile-formation process is consistent with the clean steel pile tube, on equal length, cost savings about 40%; The TSC pile tube is mainly used in the structure horizontal force resistant after combination, its concrete length requires to determine to have simultaneously the stable advantage of PHC pile tube carrying according to the Practical Project horizontal force resistant, can replace traditional clean steel pile tube, reduce cost on the basis that meets engineering demand, effectively economize on resources.

The specific embodiment
As shown in Figure 1, TSC, PHC compound pile comprise all at least one of PHC pile tube 1 and 2, two kinds of pile tube quantity of TSC pile tube.
PHC pile tube 1 structure mainly comprises the concrete hollow pile body and is located at the interior reinforcing cage of concrete hollow pile body, the two ends welded end plate of reinforcing cage.TSC pile tube 2 mainly comprises concrete hollow shape body and is coated on the outer steel pipe of concrete that end plate is established at the steel pipe two ends.
TSC pile tube 2 can be combined by the TSC pile tube segmentation of different thickness of steel pipe.Usually, TSC pile tube 2 is as the top pile body of compound pile, and concrete length needs to require to determine that PHC pile tube 1 is in the bottom according to the Practical Project horizontal force resistant; PHC pile tube 1 and the 2 concentric settings of TSC pile tube are fixed by welding or fast connecting joint 3 mechanical connections between the two.
Welding manner: PHC pile tube 1, TSC pile tube 2 are connected and fixed by inside and outside groove built-up welding between the end plate.
Mechanical connection manner: as shown in Figure 2, fast connecting joint 3 comprises a pair of mounting flange 31, and this replaces the pile end board place that traditional shirt rim is welded on respectively needs connection to mounting flange 31, and it welded before pile tube is transported to the job site.The outer end of mounting flange 31 arranges annular lip 32, and mounting flange 31 external surfaces of annular lip 32 inboards are distributed with some radial screw bore 33, and radial screw bore 33 quantity of single mounting flange 31 are nine in the present embodiment.
As shown in Figure 3, also comprise three circular arc anchor ear plates 34, its circular arc number of degrees are 120 °, three's tandem array can consist of an annulus, the inner arc center of anchor ear plate 34 has the location embeded slot 35 that arranges along the circular arc bearing of trend, the protruding outer arc of the upper and lower layer surface that embeded slot both sides, anchor ear plate 34 location form has six through holes 36 corresponding with two mounting flange radial screw bore 33, and two-layer protruding outer arc is opened respectively three.
Location embeded slot 35 width of anchor ear plate 34 are the twice of adpting flange annular lip 32 thickness, make it just can hold the mounting flange annular lip of being close to docking in two outer faces and embed.
During connection, as shown in Figure 4, two pile tubes that need to connect dock, so that two mounting flanges, 31 outer faces at pile end board place are close to, install anchor ear plate 34 at external surface, locate in the embeded slot 35 so that the annular lip 32 of two mounting flanges 31 embeds, and the through hole of anchor ear plate 34 is corresponding with screwed hole 33, by bolt 37 anchor ear plate 34 and two mounting flanges 31 are connected and fixed, by three anchor ear plates 34 that form annular pile tube are connected and fixed.
