Soft ground bridge pile foundation construction method
The invention discloses a soft ground bridge pile foundation construction method. The method comprises the following steps that S1, the preset position of a bridge pile foundation is determined in a to-be-constructed area; s2, the preset positions of the multiple high-pressure jet grouting piles are determined in the to-be-constructed area, and the preset positions of the multiple high-pressure jet grouting piles are arranged in the circumferential direction of the preset position of the bridge pile foundation; s3, jet grouting pile drill holes are dug in the preset positions of the high-pressure jet grouting piles, and high-pressure jet grouting is conducted on grout in the jet grouting pile drill holes to form the multiple high-pressure jet grouting piles; and S4, a bridge pile foundation hole is rotationally excavated in the preset position of the bridge pile foundation, and concrete is poured into the bridge pile foundation hole to form the bridge pile foundation. Thus, the strength of the soil body around the preset position of the bridge pile foundation is improved, hole collapse is not likely to happen in the rotary digging process of the bridge pile foundation hole, the hole forming efficiency and the hole forming quality of the bridge pile foundation hole are improved, the forming quality of the bridge pile foundation is improved, and then the safety and durability of the overall structure of a bridge are improved.
本发明公开了一种松软地桥梁桩基施工方法，包括以下步骤：S1、在待施工区域确定桥梁桩基的预设位置；S2、在待施工区域内确定多个高压旋喷桩的预设位置，并使多个高压旋喷桩的预设位置沿桥梁桩基的预设位置的周向方向布置；S3、在各个高压旋喷桩的预设位置挖设旋喷桩钻孔，在各个旋喷桩钻孔内高压旋喷浆液以形成多个高压旋喷桩；S4、在桥梁桩基的预设位置旋挖桥梁桩基孔，向桥梁桩基孔内灌注混凝土以形成桥梁桩基。如此，桥梁桩基的预设位置周围土体的强度得以提高，在旋挖桥梁桩基孔的过程中不易塌孔，桥梁桩基孔的成孔效率和成孔品质均得以提升，有利于提高桥梁桩基成型质量，进而有利于提高桥梁整体结构的安全性和耐用性。
