Abstract
A multi-hole type hollow pile easy to sink comprises a pile body (1) and an inner pile body (2) arranged inside the pile body (1); reinforcement uprights (3) are arranged in the inner pile body (2); a plurality of through holes (6) are formed in the central position of the inner pile body (2); a connecting part (4) is arranged at the lower end of the pile body (1); and a sinking blade (5) is arranged at an end of the connecting part (4). On the basis of an original pile, the problem that a single through hole is insufficient in strength is solved through arrangement of the plurality of through holes; and a pile tip part similar to a tubular pile is formed with the method that the sinking blade is connected to the lower end of the hollow pile body, thereby solving the problem that the hollow pile is not easy to sink.
Description
Technical field
The utility model relates to a kind of hollow pile, is specially a kind ofly can make things convenient for pile sinking in pile driving process, and has the easy pile sinking porous type hollow pile of higher-strength.
Background technology
The use of hollow pile because of its plurality of advantages, will be accepted by market, and is promoted use.Japan, as the inventor of pile tube, large-scale popularization is used from the sixties in 20th century, and in recent years, the use of its pile tube reduces year by year, and the whole nation used pile tube less than 500 myriametres in 2004; And use amount has accounted for 40% of all piles type since developing Novel pile from 2000, the advantage of visible square pile.The U.S. is similar Japan also, and the use of pre-stress hollow stake in 2003 has reached 9000 myriametres, accounts for total with 35% of stake amount.
Developed with reference to external experience and by the hollow pile that meets China's geology and make situation and to have finished, and used in a large number in engineering practice, at present from employed project situation analysis, hollow pile has been obtained good technical performance advantage.
Hollow square pile is divided into by the large I of concrete registration intensity and concrete bearing cross-section: 1. pre-stressed concrete hollow square stake KFZ; 2. prestress high intensity concrete hollow square pile HKFZ; 3. thin-walled pre-stressed concrete hollow square stake TKFZ; Wherein to be mainly used in the pure sassafras stake that rubs be main geology to TKFZ, and HKFZ is mainly used on the highrise building or the geological condition of highly corrosion resistant requirement is arranged, and the strength grade of concrete of KFZ and TKFZ is C60, and the strength grade of concrete of HKFZ is C80.The outer length of side of hollow square pile mainly contains 300 * 300～1000 * 1000, take per 50 as increment.With respect to other type, prestressed concrete pipe pile particularly, its outstanding advantage exists: 1. external surface area is large and become square or many corner types, pile body is more much bigger than round appearance with the angle of repose of soil in soil layer, this just means that hollow square pile can obtain larger bearing capacity than pile tube under equal geological conditions, for engineering is saved a large amount of basic funds; 2. from the contrast situation of following table, the bearing capacity of stake of 350 hollow square pile own will be equivalent to the heavy wall pile tube of 500 external diameters, every KN bearing capacity cost will be lower than prestressed concrete pipe pile, this means designer's preferred square pile under same design bearing capacity, and 350 hollow square pile market price is less than the heavy wall pile tube of 500 external diameters, can save a large number of cost of materials; 3. the theory of square pile calculate shearing resistance be equal pile tube 2-3 doubly, actual test according to Japan construction province, be 4.5 times of pile tube, anti-seismic performance of this explanation hollow square pile is very superior, very worth in many shakes zones and the building foundation of highrise building, In Great Basement in promote the use of; 4. hollow square pile is inherited and has been developed the low characteristics of original concrete square pile driving construction breakage rate, and high-strength concrete is mixed square head, than pile tube better impact resistance is arranged, and much smaller pile crown breakage rate; Square have larger welding girth than circular, fully guarantees the effective weld strength between every joint stake, greatly reduced square pile and joint sealing-off or offset phenomena occur in construction, makes pile quality more excellent; 5. the profile of square pile is more easily developed the fast connector of non-welding, can really accomplish all-weather construction, constructs faster, can avoid occurring in phreatic high welding pile crown cracking phenomena.
For these reasons, the research of the technology of relevant hollow pile also in the mushroom development, such as patent CN201981533U, disclose a kind of hollow pile technology, but there is obvious shortcoming in this technology, and is very inconvenient in actual applications.Namely, behind fill concrete in the interior pile body, in the process of pile sinking, can be because the pile sinking speed, and because the pressure of moment damages pile body, cause useless stake, and its reason is that the center hole that arranges in the interior pile body only has one, although this circular hole has been saved material, the intensity of himself but greatly reduces.And because this hollow pile does not have the pile top part of common pile tube, therefore, be difficult for pile sinking.
The utility model content
The application's technical problem to be solved:
The utility model is for the single through hole insufficient strength of the hollow pile that exists in the prior art, easily useless stake, and lack corresponding pile top, the shortcoming that is difficult for pile sinking proposes a kind of novel hollow pile, on the basis of former stake,, solve a plurality of through holes the problem of single through hole strength deficiency by being set, by connect the method for sinking blade in hollow pile pile body lower end, make it form a pile top part that is similar to pile tube, solve the problem that is difficult for sinking.
The application is that the technical scheme that solves the problems of the technologies described above proposition is:
A kind of easy pile sinking porous type hollow pile, comprise pile body, interior pile body, described interior pile body is arranged on the inside of pile body, be provided with lower reinforcing steel bar upright post in the interior pile body, be provided with a plurality of through-core holes in the center of interior pile body, be provided with connecting portion in the lower end of pile body, be provided with the sinking blade in the end of connecting portion.
Further, the cross section of described pile body is circular.
Further, the cross section of described pile body is square.
Further, described through-core hole is 3.
Further, described lower reinforcing steel bar upright post is 3, space 120 degree.
The obtained beneficial effect of the application is:
The utility model proposes a kind of novel hollow pile, on the basis of former stake,, solve a plurality of through holes the problem of single through hole strength deficiency by being set, by connect the method for sinking blade in hollow pile pile body lower end, make it form a pile top part that is similar to pile tube, solve the problem that is difficult for sinking.Simple in structure, have higher intensity and the performance of sinking preferably.Owing to the utility model obtains through simple the change on former hollow pile, therefore, the using and convenient operation be installed all with original substantially the same of this hollow pile.
