Abstract
The utility model relates to a thin-wall steel tube centrifugal concrete (TSC) and prestress high concrete (PHC) combined pile comprising a PHC pile and a TSC pile. The combined pile is characterized in that the number of the PHC pile and the TSC pile is at least one, the TSC pile is on the upper portion of the combined pile, and the PHC pile is arranged on the lower portion of the combined pile. The piles are concentrically arranged, and the piles are connected and fixed through welding or fast-connected joints. The TSC and PHC combined pile combines the PHC pile with the TSC pile, wherein the PHC pile and the TSC pile are connected and fixed through welding or the fast-connected joints in a mechanical connection mode. The TSC and PHC combined pile has the advantages of a pure steel pile, and is good in hit-resistant property. The pile-forming process of the combined pipe is the same as that of the pure steel pile. Cost is saved about 40% in the same length. The TSC pile is mainly used for horizontal force resistance of the structure after combination, the length of the TSC pile is confirmed according to horizontal force resistance requirements of practical engineering, and the TSC pile can replace the traditional pure steel pile. The combined pile lowers manufacture cost on the basis of meeting engineering requirements, and can effectively save resources.

Summary of the invention
It is low and meet TSC, the PHC compound pile of engineering demand that the technical problems to be solved in the utility model is to provide a kind of cost.
For solving the problems of the technologies described above, the technical solution of the utility model 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 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 end plate.
Further, described fast connecting joint comprises a pair of mounting flange, this is welded on respectively the pile end board place that need to connect to mounting flange, the outer end of mounting flange arranges annular flange flange, and the mounting flange external surface of annular flange flange inboard is distributed with some radial screw bore; Several circular arc anchor ear plates, the inner arc center of described anchor ear plate has the location embeded slot that arranges along the circular arc bearing of trend, and embeded slot both sides, location form arc convex outer arc surface 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 flange flange 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 utility model has the advantage of: 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.Both had advantages of the clean steel pile tube, durable resistance is good, and pile-formation process is consistent with the clean steel pile tube, on equal length, and cost savings 40% left and right; The TSC pile tube is mainly used in the structure horizontal force resistant after combination, its concrete length requires to determine to have advantages of that simultaneously the carrying of PHC pile tube is stable according to the Practical Project horizontal force resistant, can replace traditional clean steel pile tube, reduce cost meeting on the basis of 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, and end plate is established at 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 specifically length needs to require determine according to the Practical Project horizontal force resistant, and PHC pile tube 1 is in the bottom; PHC pile tube 1 and the concentric setting of TSC pile tube 2 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 end plate.
Mechanical connection manner: as shown in Figure 2, fast connecting joint 3 comprises a pair of mounting flange 31, and this replaces to mounting flange 31 the pile end board place that traditional shirt rim is welded on respectively needs connection, and it welded before pile tube is transported to the job site.The outer end of mounting flange 31 arranges annular flange flange 32, and mounting flange 31 external surfaces of annular flange flange 32 inboards are distributed with some radial screw bore 33, and in the present embodiment, radial screw bore 33 quantity of single mounting flange 31 are nine.
