Abstract
The utility model relates to an anti-deformation pile chuck for pile foundation construction. The anti-deformation pile chuck comprises a pile chuck bracket fixedly connected with a vibrator, and a pipe pile holding device assembled on the lower part of the pile chuck, and is characterized in that: a cylinder which is positioned between the two clamping ends of the holding device and can extend into the pipe cavity of a pipe pile is fixedly assembled on the lower part of the pile chuck bracket. By adopting the anti-deformation pile chuck, the pipe pile can be prevented from being deformed during pile pulling, and a used pipe pile can be used repeatedly after being pulled out.
Description
Technical field
The utility model relates to a kind of used anti-deformation pile chuck of pile foundation construction that is used for.
Background technology
The vibrating extractor that is adopted in pile foundation construction at present folder stake equipment occurs with pile tube crimp through regular meeting in actual use, even the problem that the head of pile tube is pulled off, and old like this pile tube just can't continue to have used, and causes waste.
The utility model content
The purpose of this utility model just is to provide a kind of pile foundation construction anti-deformation pile chuck, and it can guarantee that when pile pulling pile tube is indeformable, can reuse after making old pile tube extract.
The technical solution of the utility model is: the utility model pile foundation construction anti-deformation pile chuck, the pile tube that comprises the pile chuck support of fixedlying connected with vibrator and be assemblied in pile chuck support bottom adds holds device, it is characterized in that: fixedly be equipped with in pile chuck support bottom adding and can stretch into the intraluminal cylinder of pile tube between two bare terminal ends holding device.
The intraluminal cylinder of pile tube that can stretch into described in the utility model generally adopts solid cylinder steel body.Add described in the utility model hold device structure can for: this adds holds the arc backplate, the retractable flexible bare terminal end of being equipped with that device comprises the fixed clamp end that is equipped with the arc backplate that is fixed in pile chuck support bottom one end and is fixed in the pile chuck support bottom other end.This adds holds device and also can be set to be made of two whole retractable bare terminal ends.
The beneficial effects of the utility model are: the utility model is owing to be provided with the solid cylinder steel body that diameter is slightly less than the pile tube internal diameter, in use solid cylinder steel body is stretched in the pile tube, the clamping device of pile chuck clamps pile tube again, extract pile tube then, it has well realized guaranteeing the indeformable purpose of pile tube when pile pulling, can reuse after making old pile tube extract, the saving effect is remarkable.The utility model use has in practice been obtained good effect, has been subjected to the favorable comment of unit in charge of construction.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The present embodiment pile tube that comprises the pile chuck support of fixedlying connected with vibrator 61 and be assemblied in pile chuck support 1 bottom adds and holds device as shown in drawings.Described adding, hold device and comprise the fixed clamp end 3 that is equipped with arc backplate 5 that is fixed in pile chuck support 1 bottom one end, with arc backplate 5, the retractable flexible bare terminal end 4 of being equipped with that is fixed in the pile chuck support 1 bottom other end, this flexible bare terminal end comprises hydraulic means 4-1 and is installed in the arc backplate 5 of hydraulic stem 4-2 end.Be fixed with between two bare terminal ends in pile chuck support 1 bottom 3,4 and can stretch into the intraluminal cylinder 2 of pile tube, this cylinder is a solid cylinder steel body.
