Cast-in-place pile head guard plate structure and construction method
The invention relates to the field of civil engineering construction, in particular to a cast-in-place pile head protection plate structure which comprises a protection plate and a positioning frame, longitudinal steel bars can be positioned and inserted in the positioning frame, the distance of the outer edge of the positioning frame extending to the longitudinal steel bars is d, d is larger than or equal to 2 cm and smaller than or equal to 6 cm, and a marking part is formed on the outer edge of the positioning frame. The position of the marking part can be identified from the outer side of the pile body after the cast-in-place pile is formed; a mounting groove is formed in the inner side of the protective plate, an expandable partition part and a driving part for driving the partition part to be expanded are arranged in the mounting groove, and when the partition part is expanded, at least part of the pouring holes can be shielded, so that the partition part can separate concrete at the positions of the pouring holes. The invention further provides a construction method of the cast-in-place pile head, the positions of the longitudinal steel bars can be conveniently judged so as to prevent the longitudinal steel bars from being damaged during pile breaking, the pile head is easy to separate after being formed through the separators, and the existing problems are effectively solved.
本发明涉及土建施工领域，特别涉及一种灌注桩头护板结构，包括护板、定位架，纵钢筋能够定位插装在定位架，定位架的外缘伸出至纵钢筋的距离为d，d大于等于2厘米且小于等于6厘米，定位架的外缘形成标记部，以使得灌注桩成型后能够由桩体外侧识别标记部的位置；护板的内侧形成有安装槽，安装槽内设有可展开的分隔件、带动分隔件展开的驱动件，分隔件展开时能够遮挡至少部分灌注孔，以使得分隔件能够分隔灌注孔位置的混凝土。本发明还提供了一种灌注桩桩头施工方法，本发明能够方便判断纵钢筋的位置，以防止破桩时破坏纵钢筋，通过分隔件使得桩头成型后易于分离，有效的解决了存在的问题。
