Description

Steel reinforcement cage structure of compaction pile

Technical Field

The utility model belongs to the technical field of the compaction stake, concretely relates to steel reinforcement cage structure of compaction stake.

Background

Compaction is an effective method for reinforcing foundations above ground water level, and has been widely used in recent years. The compaction pile is formed by pressing or driving a steel pipe with a pipe plug, a valve or a conical head into soil to form a hole, compacting a soil layer, and then putting fillers such as lime soil, gravel and the like into the hole. The compaction pile is mainly characterized by no need of large digging and filling and less earth volume. The treatment depth depends on the level of the hole-forming machine and the construction technique, and a treatment depth of 5 to 15m is generally suitable.

The top end of the compacted pile is provided with a grout-turning height of 0.5-0.8m after the compacted pile is formed, the grout with few stones and incompact floating grout is removed, and the procedure of removing the 'floating grout' is called pile head breaking. The existing mode is that after concrete is solidified, an air pick is manually used for crushing the outer wall of a pile head, removing steel bars, then a cutting groove is formed at the bottom of a grout turning height, and the pile head is bent under the action of external force of an excavator, a tower crane and the like to be broken.
