Problems solved by technology

[0003] The purpose of the present invention is to provide a new construction method for manual hole-digging piles using water mill drills in view of the shortcomings of the above-mentioned construction methods. It does not need to use blasting technology, but only needs water mill drills to form the free surface, effectively avoiding holes caused by blasting. The wall is damaged and the pore size is not easy to control.

Abstract

The invention provides a water abrasive drilling construction method for a manual hole digging pile, and belongs to the field of pile foundation construction methods. An explosion technology can be prevented from being adopted, a free face is formed through water abrasive drilling, and the defects that hole wall damage is caused by explosion and the hole diameter is not likely to be controlled are effectively avoided. The water abrasive drilling construction method comprises the steps of wellbay construction, pile foundation digging and the like, and water abrasive drilling construction is adopted when pile hole digging is carried out in intensely weathered and intermediary weathered rock strata. The water abrasive drilling construction method can be used in construction of the manual hole digging pile.

Description

technical field [0001] The invention relates to the field of pile foundation construction methods, in particular to a water mill drilling construction method for artificial hole-digging piles. Background technique [0002] Manual hole-digging pile is an important hole-forming method in pile foundation construction, which has the characteristics of convenient construction, high speed, and no need for large-scale mechanical equipment. Manually dug piles are stronger in earthquake resistance than wooden piles and concrete driven piles, and their cost is lower than punching cone punching, impact cone punching, impact drilling rig punching, rotary drilling rig drilling, and caisson foundation. At present, the main construction method of manual excavation piles in China is blasting construction, which has many disadvantages. On the one hand, it will cause some damage to the surrounding residential buildings, and the compensation cost will be high, which will easily lead to civil ...
