The utility model has the advantages of: the utility model provides a length and the diameter demand of whole tubular pile not only can be satisfied in the steel reinforced concrete stake, and moreover can be free adjust length also can obtain guaranteeing simultaneously in the aspect of intensity and anti -bending strength etc..
Description
Technical field
The utility model relates to a kind of pile tube, and particularly a kind of post stretching heavy caliber SC shaped steel mixes stake or post.
Background technology
Pile tube is divided into prestressed concrete pipe pile and prestressed high-strength concrete pile by strength grade of concrete or effective compressive pre-stress.Prestressed concrete pipe pile code name is PC, and prestressed high-strength concrete pile code name is PHC, and thin-wall pipe pile code name is PTC.The concrete strength of PC stake must not lower than C60, and thin-wall pipe pile strength grade must not must not lower than C80 lower than the strength grade of concrete of C60, PHC stake.
The PC stake adopting pre-tensioning system to produce and PHC stake at home the engineering such as building, bridge are used widely, but due to the reason of the aspect such as plant equipment, transportation technology, pre-tensioning system technique is only limitted to produce external diameter 300mm-1000mm, the pile tube of joint length 7m-15m, and in the engineerings such as some large and medium-sized port and pier, bridges, mostly need to use diameter 1000mm-1400mm, the major diameter of joint length 40m-60m, overlength degree prestressed concrete pipe pile, and adopt pre-tensioning system technique cannot obtain the pile tube meeting above-mentioned requirements.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of major diameter, the post stretching heavy caliber SC shaped steel of overlength degree mixes stake or post.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of post stretching heavy caliber SC shaped steel mixes stake or post, and its innovative point is: comprise pile body body;
Described pile body body is saved by stake push pipe, middle tube coupling and stake bottom tube save assembled, and between stake push pipe joint with middle tube coupling and middle tube coupling and stake bottom tube save between seam crossing be welded and fixed by reinforcing sleeve.
Further, described stake push pipe joint, assembled between middle tube coupling and stake bottom tube joint is specially: save at stake push pipe, the relevant position of middle tube coupling and stake bottom tube joint all has several push pipe that runs through respectively and saves, the preformed hole of middle tube coupling and stake bottom tube joint, described preformed hole has several, save along stake push pipe, the circumferencial direction of middle tube coupling and stake bottom tube joint is uniformly distributed successively, by steel strand through being positioned at a push pipe joint, the preformed hole that middle tube coupling and stake bottom tube save realizes stake push pipe joint, middle tube coupling and stake bottom tube save the connection between three, and inject concrete in remaining space upon connection in preformed hole.
Further, the length of described stake push pipe joint is 4000mm, and the length of middle tube coupling is 4000mm, and the length of stake bottom tube joint is between 1000mm-4000mm.
The utility model has the advantage of: the steel reinforced concrete stake in the utility model not only can meet length and the diameter demand of overall pile tube, and can adjust length freely, also can be guaranteed in intensity and anti-bending strength etc. simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that post stretching heavy caliber SC shaped steel of the present utility model mixes stake or post.
Detailed description of the invention
Schematic diagram is as shown in Figure 1 known, and post stretching heavy caliber SC shaped steel of the present utility model mixes stake or post comprises pile body body.
Pile body body saves 3 by stake push pipe, middle tube coupling 2 and stake bottom tube save 1 assembled, and between stake push pipe joint 3 and middle tube coupling 2 and the seam crossing that saves between 1 of middle tube coupling 2 and stake bottom tube be welded and fixed by reinforcing sleeve 4.
Stake push pipe joint 3, assembled between middle tube coupling 2 and stake bottom tube joint 1 is specially: at stake push pipe joint 3, the relevant position of middle tube coupling 2 and stake bottom tube joint 1 all has several push pipe that runs through respectively and saves 3, the preformed hole of middle tube coupling 2 and stake bottom tube joint 1, preformed hole has several, along stake push pipe joint 3, the circumferencial direction of middle tube coupling 2 and stake bottom tube joint 1 is uniformly distributed successively, by steel strand through being positioned at a push pipe joint 3, middle tube coupling 2 and the stake bottom tube preformed hole saved on 1 realize stake push pipe joint 3, middle tube coupling 2 and stake bottom tube save the connection between 1 three, and inject concrete in remaining space upon connection in preformed hole, thus defined and be bonded with prestressed pile.
Carry out assembled before cleaning reserving hole channel, ensure duct clean unimpeded, assembled front worn tube coupling section laitance, concordant, greasy dirt, smooth be coated in tube coupling head by full uniformly for cementing agent; Look into adjustment to splicing station car test before splicing, time assembled, obvious mark is made in corresponding preformed hole position.
Grouting cement material should meet GB175, mixing water and additive should meet the regulation of JTS202, slip casting should under upwards hole carry out, cement paste by one end of stake to other end force feed, mud jacking should be slowly even, must not interrupt, treat that gas outlet has underflow to flow out and closes gas outlet valve, keep 2min, 0.4-0.6MPa pressure, after slip casting, cement paste compressive strength does not reach 28MPa or cement slurry adhesion stress when not reaching 0.2KN/mm, Big Pipe Pile must not handling in any form, mobile, loosen ground tackle, fixture can adopt autogenous cutting to carry out, but otch should not to rain 50mm from ground tackle, prevent ground tackle from annealing, cutting is put to open and is answered symmetry, mutual intersection is carried out.
In the utility model, GB/5224 relevant regulations should be met for selecting of steel strand, processing for ground tackle and fixture should meet GB/14370 relevant regulations, should meet the requirement that specifies of design stretch-draw, should meet GB/2567 relevant regulations for selecting of cementing agent for selecting of jack.
Wherein, the length of stake push pipe joint 3 is 4000mm, and the length of middle tube coupling 2 is 4000mm, and the length of stake bottom tube joint 1 is between 1000mm-4000mm, and concrete length can be selected according to actual needs.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
