Construction method for permanent and temporary combined high-pile wing wall of cast-in-place concrete support pile
The invention provides a permanent and temporary combined high-pile wing wall construction method for a concrete pouring support pile. The construction method comprises the following steps: S1, construction preparation; s2, surveying and setting out; s3, cast-in-place pile foundation treatment; s4, pouring support pile construction; s5, high pile wing wall construction; s6, wing wall rear reinforced soil backfilling is carried out; performing layered backfilling on the interior of the empty box and behind the wall; s7, forebay earthwork construction; filling an inverted filter layer; s8, constructing a bottom plate of the forebay; arranging a PVC drainage pipe; s9, wing wall hanging plate construction; and the wing wall forms an integrally flat surface up and down in the form of pouring the concrete hanging plate. The problem that earth excavation of the deep foundation pit of the water-rich fine sand layer is difficult is solved, earth excavation of the deep foundation pit is reduced, the requirement for the bearing capacity of the foundation is met, waste caused by dismantling of the temporary supporting piles is reduced, the construction period is effectively shortened, the construction cost is saved, and safe flood prevention and control are guaranteed advantageously.
本发明提供了一种混凝土灌注支护桩永临结合高桩翼墙施工方法，包括以下步骤：S1、施工准备；S2、测量放线；S3、灌注桩地基处理；S4、灌注支护桩施工；S5、高桩翼墙施工；S6、翼墙后加筋土回填；对空箱内与墙后分层回填；S7、前池土方施工；填筑反滤层；S8、前池底板施工；布置PVC排水管；S9、翼墙挂板施工；以浇筑混凝土挂板形式将翼墙上下形成整体平整的表面。本发明解决了富水细砂质层深基坑土方开挖难的问题，不仅减少了深基坑的土方开挖，满足了地基承载力的要求，还减少临时支护桩拆除浪费，有效缩短施工工期及节省建设成本，为安全防汛度汛起到有利保证。
