Abstract
The utility model relates to deep foundation, particularly prefabricated root foundation, which can be used for the foundation treatment of buildings or machines. The prefabricated root foundation comprises an upright main root. The utility model is characterized in that the lateral side of the main root is fixedly connected with a branch which extends laterally. Therefore, the utility model solves the problems of poor stability, weak fracture resistance capability and weak shock resistance capability of the existing deep foundation particularly when the load of the upper structure or the mechanical load of the deep foundation is large. Because the prefabricated root foundation is additionally provided with the branch, compared with the existing deep foundation, the carrying capacity of foundation concrete is increased by over 1.2 times per cubic meter. The utility model can be particularly used for the foundation treatment of large loads of the upper structures or machines or soft groundwork.
Description
The utility model relates to a kind of deep foundation.It can be used for the based process of building, also can be used for the based process of machinery.
Existing deep foundation is upright stake or hollow section, and they are embedded in the basis, are combined into one with concrete.The shortcoming of this deep foundation is: the upright stake or the cross section of hollow section are along the variation of short transverse amorphism or size, that is the side of stake or hollow section does not have abducent horizontal branch fork, therefore with its poor stability of basis of treated with same, resist fracture or the ability of antidetonation a little less than, when constructing or being subjected to load, split easily or fracture in this basis.
The purpose of this utility model is to overcome the existing shortcoming of above-mentioned existing deep foundation, and a kind of prefabricated pile foundation is provided, to improve the stability and the shock resistance on basis.
The pile foundation that the utility model is prefabricated, it contains upright main root, and its feature is: the affixed branch fork extending transversely in the side of main root.
The pile foundation that the utility model is prefabricated, main root can be that the cross section is foursquare column, and the branch fork is fixed on four sides of square column, and is horizontal arrangement.
The pile foundation that the utility model is prefabricated, main root can be the rounded columns in cross section, and the branch fork is fixed on the side of pillar type column, and is horizontal arrangement.
The pile foundation that the utility model is prefabricated, main root can be the columns that inside is hollow.
The utility model has the advantages that: prefabricated pile foundation is on original main root side after the affixed branch fork extending transversely, stability, the shock resistance of deep foundation are improved greatly, can improve more than 1.2 times as every cubic metre of supporting capacity of base concrete, even reach 1.5 times.Therefore, the load that it is particularly useful for upper building or machinery is bigger, perhaps the based process of ground weakness.
To and contrast accompanying drawing by embodiment below, the utility model will be further described below.Have in the accompanying drawing:
Fig. 1-Fig. 3 is the structure chart of the utility model first embodiment, and wherein Fig. 1 is a stereogram; Fig. 2 is a front view, and its same rear elevation, left view are all identical with right view; Fig. 3 is its vertical view;
Fig. 4-Fig. 5 is the structure chart of the utility model second embodiment, and wherein Fig. 4 is a front view, and it is identical with rear elevation, and Fig. 5 is a left view, and it is identical with right view;
Fig. 6 is the vertical view of the utility model the 3rd embodiment;
Prefabricated pile foundation vertical view when Fig. 7 is the main root of the utility model band hollow.
See the structure of the utility model first embodiment from Fig. 1-Fig. 3, this prefabricated pile foundation contains upright main root 1 and branch fork 2.Main root is that a cross section is foursquare column, and its bottom has four staking outs 3; Branch fork 2 is fixed on four sides of square column in horizontal direction, the affixed from bottom to top four row's branch forks in each side, and every row is two.Earlier ground is sunk in staking out 3 during construction, prefabricated pile foundation is firmly stood upright on the ground, irritating upward then, concrete forms the basis.
The utility model second embodiment can see from Fig. 4 and Fig. 5, it with the first embodiment difference be branch fork on the square column front and back sides with the branch fork on the left and right side not on same height, that is they stagger mutually in short transverse.
The utility model the 3rd embodiment can see from Fig. 6, and different is that main root is a cylindrical column with first and second embodiment for it.
The utility model the 4th embodiment can see from Fig. 7, and different is that main root is the column that inside is hollow with first, second and third embodiment for it.This inner space can insert reinforcing bar in construction and then poured concrete forms the basis, also can be at inner space backfill roach.
The prefabricated pile foundation of the utility model can carry out prefabricated with cement; Also available concrete or steel concrete carry out prefabricated; Also can use metal tube, perhaps metal bar weldering system forms.
