Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0037] In addition, in t...

The invention discloses pile head breaking equipment and method. The pile head breaking equipment comprises a punching mechanism and a grouting mechanism. The punching mechanism comprises a first hoop ring and a drilling machine. The grouting mechanism is used for injecting expansion slurry into expansion holes. The first hoop ring is arranged, the drilling machine is mounted on the first hoop ring, and therefore the expansion holes formed by the drilling machine are limited to be formed in the plane defined by the first hoop ring; and during static force expansion, the same plane is synchronously stressed, and a pile head can be broken more easily. Meanwhile, the grouting mechanism is arranged and used for injecting the expansion slurry into the expansion holes, and under the expansion force effect of the expansion slurry, the plane where the expansion holes are formed serves as a boundary, and the upper pile head is broken due to upward thrust applied by the expansion slurry. Compared with the manner that an impact mechanism is used for synchronous impacting in the prior art, due to the fact that the expansion force of the expansion slurry is gradually developed, the process is milder, obvious noise cannot be formed, and no negative effect is caused to surrounding personnel and nearby residents.
Description
technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a pile head breaking device and method. Background technique [0002] In order to ensure that the quality of the pile foundation meets the quality requirements, when pouring cast-in-place piles, the top elevation of the piles is usually 0.8-1.0m higher than the design pile top elevation. After the concrete is solidified and formed, it is necessary to remove the pile heads higher than the designed pile top elevation, and the work of chiseling out the concrete at this part of the pile head is called "breaking the pile head". [0003] The method of removing the pile head is divided into manual removal and mechanical removal. Manual removal of the pile head takes a long time and has been gradually replaced by mechanical construction. Existing machines for breaking the pile head use multiple impact devices to surround the pile head and strike at the same time to ...
