Construction method of detachable pile foundation steel casing in soft foundation area
The invention discloses a detachable soft foundation area pile foundation steel casing construction method, and belongs to the technical field of building engineering construction. According to the method, a limiting block with a first mounting hole is fixedly arranged on the lower section part of the steel casing, the first mounting hole is higher than the top end of the lower section part of the steel casing, a second mounting hole is formed in the corresponding position of the upper section part of the steel casing, and a fastener is matched with the first mounting hole and the second mounting hole to fix the upper section part of the steel casing and the lower section part of the steel casing. When the steel casing sinks into the soft foundation to enable the fasteners to be away from the ground by a set height, the fasteners are detached, and the upper section part of the steel casing and the lower section part of the steel casing abut against each other and are limited by the limiting blocks; and the steel casing continuously sinks into the soft foundation, and after the poured concrete reaches the preset strength, the hoisting equipment pulls out the upper section part of the steel casing. According to the detachable construction method for the pile foundation steel casing in the soft foundation area, the connecting pieces between the steel casing bodies can be detached before concrete pouring, and it is guaranteed that the positions between the steel casing bodies do not deviate.
本发明公开了一种可拆除的软基区桩基钢护筒施工方法，属于建筑工程施工技术领域。该方法通过在钢护筒下节部分固定设有第一安装孔的限位块，并使第一安装孔高于钢护筒下节部分的顶端，在钢护筒上节部分的对应位置开设第二安装孔，紧固件配合第一安装孔和第二安装孔将钢护筒上节部分与钢护筒下节部分固定，钢护筒沉入软弱基础使紧固件距离地面设定高度时，将紧固件拆卸，钢护筒上节部分与钢护筒下节部分相抵接并由限位块限位；钢护筒继续沉入软弱基础，浇筑混凝土达到预定强度后，起重设备将钢护筒上节部分拔除。本发明提供的可拆除的软基区桩基钢护筒施工方法可以在混凝土浇筑之前拆除钢护筒之间的连接件且保证钢护筒之间的位置不发生偏移。
