砂井排水法是软基加固的一种常用方法,但存在的问题是:在土质条件差而且不均匀的地方,不仅难以按连续布置形式安装排水砂井,而且也难以使砂井充分发挥排水效能。日本“千代田”化学工程建设有限公司创造出一种将砂子灌在合成纤维网形管内,并由专门设备进 Sand well drainage is a common method for soft ground reinforcement. However, the problem is that in poor and uneven soil conditions, it is not only difficult to install drainage wells in a continuous arrangement, but also it is difficult to fully drain the sand wells. efficacy. Japan’s Chiyoda Chemical Engineering Construction Co., Ltd. has created a way to fill sand in a synthetic fiber mesh pipe, and it is advanced by special equipment.
