Passive reinforcement construction method suitable for underwater cast-in-place pile
The invention provides a passive reinforcement construction method suitable for an underwater cast-in-place pile. The passive reinforcement construction method comprises the following steps that S1, a specific underwater construction position of the cast-in-place pile is determined according to design requirements; and S2, a plurality of high-pressure jet grouting piles are uniformly constructed in the circumferential direction of the center construction position of the cast-in-place pile through a high-pressure jet grouting technology, the high-pressure jet grouting piles penetrate through an underwater sludge layer, a distance is reserved between every two adjacent high-pressure jet grouting piles, the distance L between the centers of the high-pressure jet grouting piles and the center of the cast-in-place pile is equal to R + r. According to the passive reinforcement construction method for the underwater cast-in-place pile, operation is easy, use is convenient and safe, the plurality of high-pressure jet grouting piles reinforce the silt layer, namely the construction position of the cast-in-place pile in advance, meanwhile, construction of the cast-in-place pile in the follow-up drilling and grouting process is reinforced, the overall structure is simple, and stress is definite.
本发明提供了一种适用于水下灌注桩的被动加固施工方法，包括以下步骤：S1:根据设计要求确定灌注桩在水底具体施工位置；S2：采用高压旋喷注浆技术围绕灌注桩中心施工位置圆周方向均匀施工多个高压旋喷桩，高压旋喷桩2穿过水底淤泥层设置，每相邻两个所述高压旋喷桩间留有距离，高压旋喷桩中心至灌注桩中心距离L为：L＝R+r。本发明所述的水下灌注桩被动加固施工方法作业简单，使用比较方便、安全，多个高压旋喷桩对淤泥层也就是灌注桩施工位置提前进行加固，同时对后续钻孔灌注过程中灌注桩的施工进行了加固，整体结构简单受力明确。
