In the present solution, by by stake bottom squeeze into rock stratum not less than changed below 3~5 times of stake diameters and place stake top be filled to it is few The rubble of 1000mm thickness, and tamp, compacting factor is not less than 0.93, and stake can be made to be formed up and down and stablize build-in, prevent stake from drifting about.
Optionally, rubble change packing course with a thickness of 1500-2500mm.
Optionally, the compacting factor for changing the rubble after filling out is 0.95-0.90.
Optionally, this method the following steps are included:
Stake position measuring;
Rotary drilling rig is crept into deep high flow plastic peat swamps evolution, and wherein aperture is greater than stake diameter, and embedded steel pile casting is in depth Thick high flow plastic peat swamps evolution;
Rotary digging to designed elevation enters the depth of 3-5 times of stake diameter of lithosphere or less;
Steel reinforcement cage is installed;
Casting concrete;
After concrete strength reaches requirement, changing and filling out stake top or less at least cumulosol of 1000mm is rubble, and is tamped.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below will be to needed in the embodiment attached Figure is briefly described, it should be understood that the following drawings illustrates only certain embodiments of the present invention, therefore is not construed as pair The restriction of range for those of ordinary skill in the art without creative efforts, can also be according to this A little attached drawings obtain other relevant attached drawings.
Fig. 1 shows the set-up mode of the stake of the embodiment of the present invention.
Icon: 1- lithosphere, 2- peat swamps evolution, 3-, which is changed, fills out rubble body, 4- pile body.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented The component of example can be arranged and be designed with a variety of different configurations.
Therefore, the detailed description of the embodiment of the present invention provided in the accompanying drawings is not intended to limit below claimed The scope of the present invention, but be merely representative of selected embodiment of the invention.Based on the embodiments of the present invention, this field is common Technical staff's every other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
In the description of the present invention, it should be noted that if occur term " center ", "upper", "lower", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, Either the invention product using when the orientation or positional relationship usually put, be merely for convenience of the description present invention and simplification retouched It states, rather than the device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, Therefore it is not considered as limiting the invention.If only being used in addition, occurring term " first ", " second " etc. in description of the invention It is described in distinguishing, is not understood to indicate or imply relative importance.
If being not offered as requiring component absolute in addition, occurring the terms such as term "horizontal", "vertical" in description of the invention Horizontal or pendency, but can be slightly tilted.If "horizontal" only refers to that its direction is more horizontal with respect to for "vertical", not It is to indicate that the structure is had to fully horizontally, but can be slightly tilted.
