Abstract

According to the technical scheme, the cement mixing pile wall foundation pit reinforcing construction method is characterized by comprising the following steps that firstly, a line is paid off at thepile top of a cement mixing pile body, and a drilling point is determined; 2, a drilling machine is erected, and drilling is conducted on the cement mixing pile; step 3, inserting profile steel intothe drilled hole; 4, backfilling and grouting; step 5, manufacturing a coping beam steel bar template and pouring concrete; 6, positioning and drilling a pre-stressed anchor cable hole; step 7, inserting an anchor cable and grouting; step 8, tensioning the anchor cable; the post-positioned profile steel is drilled in the original cement mixing pile; the strength of the cement mixing pile is enhanced, then the tensioning anchor cable is used for tensioning anchor reinforcement, the situation that after direct implementation, the tensioning anchor cable is used for tensioning anchor reinforcement, disturbance is likely to be generated on a cement mixing pile body, a pile wall generates large displacement, and cracks or pile body breakage is generated due to the fact that reverse pulling force is forcedly applied is reduced, and the supporting effect of the supporting structure is improved.

Description

technical field [0001] The invention relates to the field of foundation pit reinforcement, more specifically, it relates to a cement mixing pile wall foundation pit reinforcement construction method. Background technique [0002] In the early stage of building construction foundation and foundation engineering construction, foundation pit support is a time-sensitive and risky project. Due to the limitations of geological exploration, the complexity of construction operations and the unpredictability of natural environments such as weather, There are often unstable factors in the foundation pit support construction process, which leads to the loss of the original support capacity of the foundation pit support structure, which greatly reduces the safety of the construction process and delays the construction period. [0003] As the most unpredictable factor among the influencing factors of construction work, the construction environment brings great instability to the quality ...
