Construction method for cleaning mud blocks on blades of spiral drilling machine

Abstract

The invention discloses a construction method for cleaning mud blocks on blades of a spiral drilling machine. The method comprises the steps that firstly, mud block cleaning equipment for the blades of the spiral drilling machine is installed; 2, mud blocks on blades of the spiral drilling machine are cleaned; 3, repeated cleaning; and fourthly, the pile body mud cleaning equipment is dismantled. The method is simple in step and low in operation requirement, all the blades of the spiral drilling machine drilling are cleaned by arranging the mud block cleaning equipment for the blades of the spiral drilling machine, the equipment composition cost is low, durability is good, dismounting and mounting are convenient, and the situation that mud blocks fall off in the construction process, and consequently safety accidents are caused is avoided; and meanwhile, the mud block detection mechanism is used for detecting the mud block condition on the blade, the mud block cleaning efficiency is improved, and the extension time and frequency of a desilting oil cylinder can be conveniently adjusted under different working conditions.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for cleaning mud on blades of an auger drilling machine. Background technique [0002] At present, in the field of CFG pile construction in my country, it is not uncommon for people to be injured by falling objects from high altitudes when long auger drilling rigs are used for construction. The falling objects are mainly pile mud sticking to the blades of the drill pipe. Two methods are routinely used for on-site desilting: One is manual cleaning with tools; the other is mechanical cleaning with 60 small excavators. When a long auger is used for construction, the auger pipe often rises above the ground from the underground soil layer, and the silt or clay between the helical blades cannot fall from the blades by itself like sandy soil, but will rise with the auger pipe , rise to a high place, be shaken, and will fall from a high pla...

Problems solved by technology

When a long auger is used for construction, the auger pipe often rises above the ground from the underground soil layer, and the silt or clay between the helical blades cannot fall from the blades by itself like sandy soil, but will rise with the auger pipe , rise to a high place, be shaken, and will fall from a high place, which will bring safety hazards to the construction. Using iron scrapers to unload the mud will not only increase the labor intensity of the workers, but also increase the construction cost; at the same time, if the cleaning speed cannot keep up, When the soil is lifted together with the drill pipe, it may fall and cause damage to the object, which brings great safety hazards to the workers on site. In addition, when cleaning the drill pipe, it is also necessary to climb up and remove it, which also brings safety and civilization to the construction site. Great hidden danger
