It is forbidden to pile materials around the foundation pit.

According to the information of Bao Zheng Construction Engineering Education Network, the ground around the foundation pit should be provided with drainage ditches, and the foundation pit should also be provided with necessary drainage facilities. 1 ~ 2m It is forbidden to pile up materials, earthwork and other heavy objects and park or drive large construction machinery at the top of foundation pit.

Loading in the range of 1 to 2m at the edge of foundation pit will increase the shear stress of soil, which is prone to landslide and collapse, especially in rainy and snowy weather. Therefore, when dealing with other materials, observation points should be set up around the original buildings and public facilities, and special personnel should be arranged to take charge of them, observe them in time, and take immediate measures if abnormal conditions are found.
