Abstract

The invention relates to the technical field of pile hole empty pile segment mud construction, and discloses a construction method for treating mud of an empty pile segment of a pile hole through a curing agent. A dual drilling rod is included. The method comprises the following specific steps that (1) tap water is injected into a stirring pond, the curing agent is added into the stirring pond, stirring is carried out, and slurry with the ratio ranging from 0.5 to 0.8 is obtained; (2) the dual drilling rod is adopted for slurry injection, a first connector and a second connector are formed atthe top of the dual drilling rod, the first connector communicates with compressed air, the second connector communicates with the slurry, the dual drilling rod downwards stretches into the bottom ofmud on the empty pile segment, the compressed air and the slurry are mixed and constantly turned over in the empty pile segment, and meanwhile a great number of bubbles are generated to return mud upwards; (3) the dual drilling rod is pulled out; and (4) standing is carried out for 2-4 days, and sufficient curing is carried out. The compressed air and the slurry are conveyed at the same time, thehydration reaction degree is higher, the mud curing speed is higher, construction is extremely convenient, the construction cost is lower, and the efficiency of carrying out mud treatment constructionon the empty pile segment of the pile hole is greatly improved.

Description

technical field [0001] The patent of the present invention relates to the technical field of slurry construction of empty pile sections in pile holes, and specifically relates to a construction method for curing agent to treat slurry in empty pile sections of pile holes. Background technique [0002] As more and more pile foundation projects are constructed on the surface before the excavation of the foundation pit, once the construction of the engineering piles is completed, the foundation pit needs to be excavated later, and the part within the depth of the excavated foundation pit is an empty pile part. [0003] During pile foundation construction, the empty pile section does not need to place reinforcement cages and pour concrete. Only the reinforcement cage is placed in the lower solid pile section. When pouring pile hole concrete, it can only be poured to the bottom of the foundation pit (the bottom of the empty pile section) , so there are more than ten meters or eve...
