Foundation pit excavation drilling device and method for building construction
ActiveCN119308593Aeasy to cleanEasy to reamDrill bitsDrilling with mechanical conveyingHydraulic cylinderArchitectural engineering
The invention relates to the technical field of building construction foundation pit excavation, and discloses a foundation pit excavation drilling device and method for building construction, the device comprises a drilling assembly, the bottom end of the drilling assembly is slidably connected with reaming assemblies in an array mode, a hydraulic driving part is arranged in the drilling assembly, and a rotating driving part is arranged at the top end of the drilling assembly; the top end of the drilling assembly is rotationally connected with a guide assembly, a hydraulic cylinder is fixedly installed on the surface of the guide assembly, and a muck guide part is fixedly installed on the inner side of the bottom end of the guide assembly. When the drill bit drills to a preset depth, an electric control valve is closed, hydraulic oil is conveyed into an oil storage barrel through an oil injection pipe, so that the hydraulic pressure in a hydraulic cavity is increased, a piston plate is driven to move downwards, a sliding column extrudes a sliding block downwards, and a crushing blade extends out of the drill bit to be matched with rotation of the drill bit to enlarge the diameter of a drilled hole; and an assembly body of the drill bit and the crushing blade moves upwards while rotating, so that the purpose of conveniently reaming after drilling is achieved.

A kind of boring and grouting pile construction equipment and construction method for complex geological conditions
ActiveCN118774600BImprove construction efficiencyeasy to operateDrill bitsDrilling without earth removalTool bitArchitectural engineering
The present invention relates to the technical field of bored pile construction, and specifically to a construction equipment and method for bored piles in complex geology. The bored pile construction equipment includes a drilling machine and a multi-stage drill bit installed on the drilling machine. The multi-stage drill bit includes a rotating drill rod and a plurality of hole expansion rings evenly arranged along the axis direction of the rotating drill rod. The hole expansion ring is installed on the outer ring surface of the rotating drill rod through a connecting rod. A tool holder bar is evenly installed on the bottom of the hole expansion ring. The bottom of the tool holder bar is installed on the outer ring surface of the rotating drill rod. A cutting tool head is evenly installed on the side of the tool holder bar away from the rotating drill rod. The present invention drives the rotating drill rod to rotate through the drilling machine, and the tungsten steel drill bit first drills the foundation, and then the cutting tool head on the tool holder bar with an inclined structure regularly expands the hole one level at a time. After each hole expansion is completed, the hole expansion ring completes the stable hole formation. This process can form a hole in one time, increase the construction efficiency of the drilling, and is easy to operate.

Flange hole expanding and forming device
ActiveCN224347485UReduce dust contentavoid scratchesPositioning apparatusMaintainance and safety accessories
This utility model relates to the field of flange reaming, and discloses a flange reaming forming device, including a processing table. The top of the processing table is equipped with an air blowing and chip suction mechanism and a translational clamping mechanism. The air blowing and chip suction mechanism includes a conical cylinder with an air outlet chamber and an air inlet chamber on its inner wall. A bidirectional motor is fixedly connected to the inner wall of the air outlet chamber, and a rotating shaft is fixedly connected to the output end of the bidirectional motor. A reaming drill is fixedly connected to the bottom end of the rotating shaft, and a fan blade is fixedly connected to the top end of the rotating shaft. A filter box is fixedly connected to the outer wall of the conical cylinder, and the filter box is connected to the air inlet chamber. In this utility model, by setting up the air blowing and chip suction mechanism, large pieces of waste material generated during reaming can be blown away from the flange, preventing large pieces of waste material from remaining on the flange and affecting the reaming process, and preventing waste material from scratching the processed surface. The chip suction hood sucks up smaller pieces of waste material, reducing the dust content in the workshop air.
